Consequently erectile dysfunction and stress buy cialis super active 20mg visa, Board members can ensure that the project has all the necessary resources erectile dysfunction systems cialis super active 20 mg with visa, including people erectile dysfunction drugs used purchase cialis super active 20mg amex, funding erectile dysfunction is often associated with quizlet purchase cialis super active 20 mg otc, and time impotence merriam webster purchase line cialis super active. Their allocation of resources can show strong political support for change erectile dysfunction doctors orange county buy cialis super active with a mastercard, which can sustain ongoing motivation and momentum for that change. Board members often have a wide range of useful skills that can aid in governing the organization, such as planning, leadership, management, supervision, and problem-solving. Giving them yet more work to do (during the change process) can completely overload them resulting in a failure to achieve desired results. The Board can provide a more objective assessment on specific project issues and results than staff. Board members usually are not involved a great deal in the day-to-day activities of the organization. Consequently, they often retain an objective perspective on its activities and resulting changes. Their perspective can be useful when addressing issues in various projects and evaluating the quality of change in the organization and the results achieved. One of the best ways to get good Board members is to give them something meaningful to do. Bill Berger, the past chairman of the president of the American College of Allergy, Asthma, and Immunology, stated: I believe that the functions of leadership involve creating a purpose and sense of community, fostering commitment rather than compliance. Successful leadership inspires trust by integrating diverse views, supporting skillful conversations through dialogue, and helping others exert their influence. This sharing of leadership is accomplished by constantly facilitating, energizing, and sustaining others while encouraging achievable tasks, creating a proper perspective of history and hope, and leading to a collective vision for the future. Large-scale organizational change usually triggers emotional reactions, including denial, negativity, reluctant choice, tentative acceptance, or resistance to commitment. Exercise 29: With your staff, choose one major socioeconomic change occurring in your community or region. Have a dialogue about that change to ensure that everyone is in agreement about the nature and significance of that change. Then have a dialogue about the implications of that particular change on the functioning and direction of your organization, and how the organization itself might have to change to deal more effectively with that external change. A leader is one who sees more than others see, who sees farther than others see, and who sees before others do. Some of the previous chapters described the character, behavior, competencies, and skills needed to be an effective leader. Regardless of the particular leadership traits or styles that a leader adopts or skills that are acquired, he/she must have vision. No one can be a leader without followers, and no one will follow someone unless it is clear where he or she is headed. That direction comes from a vision, which is an ideal and unique image of the future. It articulates a view of the future as the leader sees it, a future condition that would be better in some important ways than what now exists. David Kolzow 241 If your actions inspire others to dream more, learn more, do more, and become more, you are a leader. Visions come to those who have a well-informed and open mind, one which is prepared by a lifetime of learning and experience. However, the more that someone is strongly aware of emerging trends and developments that impact a community and its organizations, the more likely that individual will have a reasonable understanding of the range and nature of possible future scenarios. Core values go a long way in determining what really matters to an individual or to an organization. They guide the choice of information being sought to answer these questions and how the information is evaluated. All of this guides the decision as to what vision to pursue among the various possibilities. Truly inspirational leadership is showing people how the vision can directly benefit them, how their specific needs can be satisfied. If people relate to the company they work for, if they form an emotional tie to it and buy into its dreams, they will pour their heart into making it better. To choose a direction for an organization, its leaders must first have developed a mental image of what they believe the future of the organization can and should be. Good leaders constantly communicate a clearly articulated destination toward which the organization should aim. There is no more powerful engine driving an organization toward excellence and long-range success than an attractive, worthwhile, and achievable vision of the future, widely shared. As organizational learning expert Peter Senge has observed, vision translates 242. In my experience, it is only through a compelling vision that a deep sense of purpose comes alive. When members of the organization see positive results and see goals being met, they get a clearer picture of what it means to fulfill the vision. Values and cultures can become so deeply rooted and persistent that they can actually constrain the transforming of the organization. As was quoted in Chapter 8 on Change, Tom Peters, in his book, Thriving on Chaos, states that the most obvious benefit of unsettled times is the unique opportunity they afford to create rapid change. In a community, new or expanded visionary leadership often emerges from unsettled and chaotic conditions. Individuals with a positive attitude who are willing to embrace change and take some risks can help move the community in a desired direction. All of this is also true of the development organizations that serve the community. Additionally, the leadership must also live the vision, demonstrating in their behavior the importance of this future state. Although leaders drive the vision, individuals within the organization also need to believe that they can make a difference in achieving organizational excellence. It is important that they believe that they can play a part in improving the organization in which they are working through their participation in its various activities. People need to find meaning in their work, and a clear vision defines that meaning. Research indicates that leaders who demonstrate strong visionary leadership have the highest performing organizations. With increased confidence and skill, the people doing the work recognize that they can actually accomplish more than they may have believed was possible. Because economic development planning in most organizations needs to have a relatively long-term focus and direction, a widely accepted vision also facilitates continuity of effort regardless of changing leadership and changing conditions. It is becoming widely accepted that leadership is vitally needed throughout all levels of modern organizations. However, within the context of these overriding organizational visions, a need exists for visioning at the staff and mid management level as well. David Kolzow 245 empowerment of employees requires a common understanding of what is needed at their level in order for the organization to achieve the quality it seeks. Furthermore, one way to ensure that vision formation is a continuous process is by spreading the leadership role throughout the organization at every level, so that every operating unit is encouraged to develop its own vision. One of the more important criteria for selecting leaders below the level of top management should be their ability to create and implement visions for their particular area of responsibility. Once an individual has been selected for a leadership position, his or her visioning skills can be enhanced with well-designed training and development programs. People can be put in positions where they observe other visionary leaders in action or where they are mentored by such individuals. These emerging leaders should be encouraged to develop and articulate visions appropriate to their level of operation. The experience gained from the ongoing efforts to envision will facilitate the development of these leaders and help them move into more responsible and higher-level positions. When people share a vision, they are connected and bound together by a common aspiration. Common values and beliefs are the fundamental principles that guide an organization. This process has to engage them in a way that gets them thinking about the desired future for the organization on which they can all come to some level of agreement. A successful vision for an organization should never be the product of one individual, even if that individual is the executive director of the organization. The following exercise is one example of such a group visioning process that can be readily used within the organization. The organization is successfully serving the needs of its customers, clients, and constituents. Please describe in writing your opinion of what are the five most important characteristics of this organization five years from now. The participants will then be dismissed to their small groups or will begin working with their facilitator. Ask each member of the small group to share, in turn, one of his/her characteristics of the organization ten years from now. If the component or characteristic is similar to one already stated, try to combine them. If it is identical to something already stated, ask for another component from the individual. Go through the list with the group and consolidate those characteristics that are similar. Start with the first characteristic and determine if there is group consensus on the inclusion of it within a vision statement for the organization. After you have determined those characteristics for which there is consensus, go back through the remaining to determine if consensus could be developed on any of those if minor changes or modifications could be made concerning the characteristic. Add those characteristics for which there is consensus to the list and eliminate those without consensus. Working with the group, try to determine the priorities of the vision David Kolzow 249 components. Give each component either an "H" for high priority or very important, "M" for moderate priority, or "L" for low priority or not very important. If complete consensus does not exist in rating a particular component, give the appropriate rating that the majority of the group believes is correct. Rewrite the high priority components on a flipsheet to bring it back to the group as a whole for discussion. The Executive Director of the organization should will take the results of the visioning exercise. This should then be submitted to the Board or the Executive Committee of the Board for review, comment, and eventual adoption. The vision must be communicated in a compelling way, by translating it into operational steps that everyone can understand, especially those who have the responsibility of following it up with action. Responsible leaders know that not only must they change the culture of business-as-usual, they also must help people through the uncertainties of the change. It is likely that key stakeholders and others will need to be persuaded to change their perceptions about what is important for the future of the organization. David Kolzow 250 Additionally, leadership must consistently demonstrate how the vision applies to daily organizational life. The job of the leader or leaders is also to support people in accomplishing the vision by removing barriers in the organizational system, including any that top management might be responsible for in its policies and practices.

Carrying out a proctocolectomy with a final erectile dysfunction drugs at walgreens discount cialis super active 20mg on line, permanent ileostoma can in most cases nowadays be avoided erectile dysfunction treatment in pune purchase 20 mg cialis super active visa. Because several patients develop polyps in the area of the pouch next to the ileoanal anastamosis that can progress to cancer impotence lisinopril cialis super active 20mg amex, an annual postoperative pouchoscopy is recommended erectile dysfunction acupuncture cheap 20 mg cialis super active mastercard. If no proctocolectomy was performed best erectile dysfunction pills 2012 purchase cialis super active mastercard, surveillance of the rectal stump with short intervals of no more than 12 months are necessary erectile dysfunction statistics race purchase cialis super active in india. The interval should be shortened up to one year depending on the degree of severity of the adenoma burden (Spigelman classification). If duodenal-/papillary adenomas are identified, an indication for endoscopic polypectomy should be considered. Fewer than 10% of the patients develop gastric adenomas, more than 50% have fundic gland polyps of the stomach. Gastric cancer, however, do not seem to occur more often than in the general population [308]. With regard to the extent of duodenal polyposis, the Spigelman classification (see Table 7) should be used [309]. The average age of patients with serious adenomatosis of the duodenum is about 43 (range 24-65) [235]. Altogether, it appears that the growth behavior of duodenal adenomas is slower than that of colorectal adenomas [310, 311] and depends more on increasing age (increases at age >40) than on the initial stage [312]. The mutation location (Codon 279 1390) correlates with the severity of the polyposis in the duodenum, but not with the possibility that a high-grade dysplasia will develop [313, 314]. The risk that an invasive cancer is present depends on the severity of the duodenal polyposis. The aim of an endoscopic surveillance is not the removal of all polyps, but the detection of relevant neoplasias (high-grade intraepithelial neoplasia, villous or tubolovillous adenomas). In case of smaller polyps, the larger ones should be removed and sent to pathology to determine the Spigelman score. The pancreas-maintaining duodenectomy is the preferred procedure partly due to a lower morbidity rate than with a pancreatic duodenectomy [319, 320]. An operative duodenotomy with polypectomy cannot be recommended due to a high rate of recurrence [321, 322]. In principal, even after extensive surgical treatment the appearance of new adenomas cannot be prevented [321]. Currently, it is not clear whether regular duodenal screening prolongs life [315]. In case of progressive desmoids under this drug therapy an interdisciplinarily approach should be undertaken. About 50% of the desmoids appear intra-abdominally especially mesenterially and due to their local infiltrative growth often cause significant problems. Desmoid tumors that are asymptomatic and not progressing in size often do not have to be treated. A systematic review of published clinical trials on medicinal non-cytotoxic chemotherapies demonstrates the best confirmed efficacy for treatments with sulindac (300 mg), tamoxifen (40-120 mg), or a combination therapy [328]. Progressive tumors under sulindac or antihormonal therapy should be treated with chemotherapy (doxorubicin and dacarbazine or methotrexat and vinblastin) or radiotherapy [330-332]. Especially for intra-abdominal desmoids, incomplete resections and high relapse rates are often reported [334-337]. For abdominal wall desmoids surgical procedures often lead to R0-resection and no recurrence [335]. About 95% of all reported thyroid cancer affect women; therefore, the risk is mainly increased in female carriers. Histologically a cribiform variant of a papillary thyroid cancer is usually present. Two prospective [339, 340] and one retrospective study [341] examined the value of a one time ultrasound screening. In the largest study cancer were only detected through ultrasound and not using patient history or palpation [339]. The frequency of necessary adjuvant radiotherapy can possibly be reduced if more microcarcinomas are detected. Due to the rarity and the unclear data on whether the prognosis for hepatoblastoma patients can be improved, screening is not generally recommended [346, 347]. Evidence-based Recommendation 2013 Grade of Drug treatment of adenomas in the lower and upper gastrointestinal tract should Recommendation not be generally recommended. B Level of Evidence Evidence from update literature search: [348-356] 2b Strong consensus Background Sulindac reduces the number of colorectal adenomas by more than 50% [348-352]. Celecoxib at high doses of 400-800mg reduces the colorectal polyp number by 28% [354] and also affects duodenal polyposis [355]. However, it is not known whether its use also reduces the risk of developing cancer in these patients. Presently, they should only be used in selected cases with strict indications (risk-benefit assessment). Patients who do not undergo a colectomy should have a B colonoscopy once a year for the rest of their lives. If no polyps are found at this point, these persons should have an annual colonoscopy starting at age 20. Hence, a complete colonoscopy must be performed for surveillance [256, 257, 259, 260]. Because of significant variations of clinical characteristics, the decision concerning therapy must be made on an individual basis. For patients with an indication for an operation, but fewer than five rectal polyps, an ileorectal anastamosis with a remaining rectal stump is reasonable. It is unclear with the current amount of data available to determine up to which age surveillance of persons at risk with negative findings should be performed. Predictive genetic diagnostics after human genetic counseling should be recommended to these persons from age 18 20. However, the benefit of conclusive genetic results is opposed to the (rare) identification of functionally unclear genetic variants. Conclusions in individual cases on their pathogenic relevance and, thus, clinical consequences (currently) are not possible. A complete colonoscopy should, thus, be considered at the age of about 30 to 40 years. Patients who have not been colectomized should have lifelong annual colonoscopies. A recommendation for drug treatment of adenomas in the upper and lower gastrointestinal tract cannot be given, because of missing data. Therefore, as a screening method a complete colonoscopy must be performed [256, 257, 259, 260]. Since the clinical manifestation varies greatly, therapy decisions should be made individually. For patients who have an indication for surgery and who have few rectal polyps, an ileorectal anastomosis leaving a rectal stump may be justifiable [364]. The only systematic study in 276 patients that investigated this issue demonstrated a small to moderate, but significant increase in ovarian, bladder, and skin cancer incidence as well as a trend toward increased risk of breast cancer [271]. However, there was no dominating extra-intestinal tumor and no shift towards an earlier manifestation (median age at diagnosis of the 4 malignomas was between 51 and 61 years of age). Evidence-based Statement 2013 Level of Evidence these include especially hamartomatous polyposis-syndromes (Peutz-Jeghers syndrome, familial juvenile polyposis, Cowden-syndrome), hyperplastic polyposis 2a syndrome, and hereditary mixed polyposis. Evidence from update literature search: [263, 366-396] Background In individual cases the differential diagnosis of non-adenomatous polyposis-syndromes can be very difficult and demands interdisciplinary collaboration of gastroenterologists, surgeons, pathologists, human geneticists, radiologists, and other clinical experts (especially gynecologists, urologists). Thus, children (and if present siblings) of an affected person have a 50% risk of inheriting the underlying genetic mutation and to develop the disease in the course of their lifetime. It is characterized by the occurrence of hamartomatous gastrointestinal polyps and mucocutaneous melanin pigmentation which is especially visible peri-oral. Peutz-Jeghers-polyps occur especially in the small intestines and demonstrate characteristic histology. A mutation can be identified in more than 90% of patients who fulfill the clinical-diagnostic criteria [367]. Complications in children include an acute abdomen caused by invaginations or an obstructive ileus as well as chronic bleeding with secondary anemia. Overall, for tumors in the gastrointestinal tract there is a cumulative lifetime risk of 57%. Cervical cancer occur with a lifetime risk of 9% and are histologically similar to adenoma malignum in more than 75 % of the cases [377]. The correct diagnosis of juvenile polyps can be difficult due to morphologic similarities with hyperplastic polyps as well as lymphocytic infiltrates and displastic portions: a considerable percentage of genetically confirmed cases of juvenile polyposis are initially misdiagnosed as ulcerative colitis or hyperplastic polyposis [379, 380]. Therefore, in case of doubt, a second review of the histologic sample by a gastroenterologically experienced pathologist should be sought. The disease can already become noticable in early childhood due to chronic gastrointestinal bleeding or exsudative enteropathy with concomitant delayed development. In case of very severe early manifesting courses juvenile polyposis of toddlers should be considered [387]. It is usually done using primarily the extra-intestinal tumor spectrum and molecular genetics. Cowden-syndrome [388] is especially associated with a higher risk of breast and thyroid cancer. Furthermore, increased risks for endometrial and renal cancer as well as melanomas were reported. The Bannayan-Riley-Ruvalcaba-syndrome is viewed as a variant of the Cowden-syndrome. However, they are rare and, so far, both clinically and genetically poorly characterized. Consensus-based Recommendation 2013 Due to the scarce data, general screening recommendations cannot be given. Consensus Background Valid screening recommendations cannot be given, because of the scarce data available. Specific screening programs were suggested by individual experts for the more frequent syndromes. The published guideline for Peutz-Jeghers-syndrome has methological deficits and gives only little evidence for most of the recommendations [397]. For some of the syndromes, experts suggested specific age dependent screening programs (review in [263]). However, the recommendations are contradictory and, due to the few case numbers, the efficacy of the very rare syndromes is difficult to validate. Specific recommendations are given in the S3-Guideline on Diagnostics and Therapy of Ulcerative Colitis. Evidence-based Recommendation 2013 Grade of Since the colitis-associated colon cancer mortality can be decreased by using Recommendation endoscopic screening, regular monitoring colonoscopies should be performed. This should be done regardless of the disease activity to assess the disease extent. A Level of Evidence [401] 4 Consensus 5 In the guideline ulcerative colitis a different level of evidence is used Evidenzgrad (398. A Level of Evidence [405] 4 Strong consensus Comment A meta-analysis by Collins from the year 2006 summarizes the direct and indirect evidence on monitoring colonoscopies for ulcerative colitis. The three identified case control studies did not show a statistically significant colon cancer risk reduction. It should be noted that, from a present day perspective, these were small studies with partially inadequate colonoscopy standards. In contrast, the meta-analysis gave clear from indirect evidence that monitoring colonoscopies very likely reduce the risk of dying of a colitis-associated colon cancer [399]. This is the reason that patients with pancolitis should begin regular monitoring earlier than patients with distal colitis. An initially distal colitis inflammation can develop into a pancolotis without clinical evidence. Therefore, a screening colonoscopy should be done within 8 years after the first disease symptoms appeared to check the extent and then to decide on a monitoring strategy. A Dutch study indicates that already up to 22% of patients have developed colitis-associated colon cancer before starting the monitoring colonoscopies recommended so far [406]. The screening interval should not exceed 2 years, because interval cancer can already arise in this period [401, 402]. Since for proctitis the risk is only minimally increased at most if other risk factors are not present regular surveillance is not necessary. After subtotal colectomy, cancer can occur in the remaining colon, as well as after restorative proctocolectomy in the pouch or depending on the operation technique in the area of the remaining colon mucosa distal to the anastomosis [405]. The benefit of screening programs with ileocolonscopies to screen for cancer in Crohn colitis is unknown. Evidence-based Statement 2017 Level of Evidence the complete colonoscopy is the standard procedure for the detection of colorectal polyps and cancer. Evidence-based Recommendation 2017 Grade of If a colonoscopy was incomplete due to other causes. Important quality characteristics include an endoscopic examination all the way to the caecum, optimal preparation of the colon with few or no remaining stool residues and a thorough inspection of the intestinal mucosa when withdrawing the endoscope.

Young people appear to have saturation of the graduate job market and underemployment internalized irrational social ideals of the perfectible self that, among graduates in developed countries. Although their poor achievement reflects their inadequate personal abilities written some time ago, Hamachek (1978) stated on the link between. In turn, because individuals cannot expanded upon in the recent writing of Hewitt et al. Whereas education culture in that striving for high achievement standards and the attain has historically sought to provide young people with a broader ment of perfection are actively encouraged and rewarded. Young repertoire of skills and knowledge, neoliberal meritocracy stresses people are taught that the principles of meritocracy are good, fair, and that skills and knowledge are worthless unless they confer eco just. In response, they are compelled to demonstrate their merit, set nomic value (Verhaeghe, 2014). This places considerable pressure increasingly higher and unrealistic goals, and come to define them on young people to strive, compete, and meet increasingly higher selves in the strict and narrow terms of personal achievement. The effects of merging academic and eco Altered Parental Practices and Perfectionism nomic meritocracies are reflected in the escalating educational expectations of young people. In the United States, where cohort As we have described, neoliberalism and its doctrine of meri data is available, approximately half of high school seniors in 1976 tocracy have combined to shape a culture in which everybody is expected to attain at least some college degree, by 2008 that figure expected to perfect themselves and their lifestyles by striving to had risen to over 80% (Jacob & Wilder, 2011). For parents, this new attainment has failed to keep pace with rising expectations. On top of their own duty to gap between the percentage of high school seniors expecting to succeed, they are also responsible for the successes and failures of obtain a college degree and the percent of young people with a their children (Verhaeghe, 2014). Intense competition for elite world, are at extremes that psychologists have noted are cause for college admission has meant that, relative to previous generations, concern (Sevilla & Borra, 2015). Foremost, there is evidence that recent scribed perfectionism, and other-oriented perfectionism with the generations of parents are responding to pressure by spending far year of data collection. As college students are approximately the more time with their children on academic activities. This trend same age, data collected from the Multidimensional Perfectionism sits alongside a reduction in the amount of time parents report Scale at different time points provide a test of birth cohort differ spending with their children doing other activities such as leisure ences for generational variability. Since the early 1990s, mothers in the United States how levels of perfectionism have changed, at the cohort level, have reallocated over 9 hr per week from leisure time to childcare, since the late 1980s. In line with the theoretical and empirical including 2 additional hours per week afforded specifically to evidence provided earlier, we expect that year of data collection education (Ramey & Ramey, 2010). Beyond increasing time dedicated to childcare, pressure on Method parents to secure a successful future for their children has more substantive effects on parenting itself. This is because parents act as social sertations & Theses (American & International and the United conduits, passing their own achievement anxieties onto their chil Kingdom & Ireland).

In students are demanding higher expectations of themselves and the case of self-oriented perfectionism, if the average college attaching more importance to perfection than previous generations. This earlier on several cultural shifts that include competitiveness, means that 55% of college students in 2017 were above the 1989 individualism, meritocracy, and anxious and controlling parental mean self-oriented perfectionism score, which amounts to a 10% practices that may be promoting perfectionism generally. For socially prescribed perfectionism, if the average two appear especially likely to instill an inner personal desire to college student in 1989 scored at the 50th percentile of the distri strive for perfection (Sherry, Mackinnon, & Gautreau, 2016). Accordingly, nearly two thirds of college students in observed for self-oriented perfectionism in comparison to the other 2017 were above the 1989 mean socially prescribed perfectionism dimensions of perfectionism. In the case of other ism akin to self-oriented perfectionism have been found to have oriented perfectionism, if the average college student in 1989 higher heritability than other dimensions, perhaps this is not sur scored at the 50th percentile of the distribution, the average college prising (see Tozzi et al. Hence, nearly three perfectionism is the least amenable to change and therefore less fifths of college students in 2017 were above the 1989 other affected by broader cultural shifts (Hewitt et al. Alongside the effect of time, American college students ap Discussion peared to report higher self-oriented perfectionism than Canadian and British college students. Regarding why this might be the case, In the current study, multidimensional perfectionism measure some researchers have suggested that the United States has be ments from 164 samples and 41,641 American, Canadian, and come hyper-individualistic in recent decades (Klein, 2012).

Therefore, When holding between country differences in mean scores the especially strong individualistic and meritocratic culture in the constant, we found that self-oriented perfectionism increased over United States may explain why self-oriented perfectionism is time.

For weight-bearing physical activities erectile dysfunction forums buy 20mg cialis super active amex, the cost is roughly proportional to body weight erectile dysfunction drugs from canada generic 20 mg cialis super active with amex. In the life of most persons impotence from prostate removal purchase cialis super active toronto, walking represents the most significant form of physical activity erectile dysfunction after testosterone treatment purchase 20mg cialis super active with mastercard, and many studies have been performed to deter mine the energy expenditures induced by walking or running at various speeds (Margaria et al erectile dysfunction causes purchase generic cialis super active on-line. Walking at a speed of 2 mph is considered to correspond to a mild degree of exertion erectile dysfunction treatment abu dhabi generic 20 mg cialis super active with mastercard, walking speeds of 3 to 4 mph correspond to moderate degrees of exertion, and a walking speed of 5 mph to vigorous exertion (Table 12-1, Fletcher et al. Over this range of speeds, the increment in energy expenditure amounts to some 60 kcal/mi walked for a 70-kg individual, or 50 kcal/mi walked for a 57-kg individual (see Chapter 12, Figure 12-4). The increase in daily energy expenditure is somewhat greater, how ever, because exercise induces an additional small increase in expenditure for some time after the exertion itself has been completed. Taking into account the dissipation of 10 percent of the energy consumed on account of the thermic effect of food to cover the expenditure associated with walking, then walking 1 mile raises daily energy expenditure to 76 kcal/mi (69 kcal/mi 1. Since the cost of walking is proportional to body weight, it is convenient to consider that the overall cost of walking at moderate speeds is approximately 1. Energy expenditure depends on age and varies primarily as a function of body size and physical activity, both of which vary greatly among individuals. However, it is now widely recognized that reported energy intakes in dietary surveys underestimate usual energy intake (Black et al. A large body of literature documents the underreporting of food intake, which can range from 10 to 45 percent depending on the age, gender, and body composition of individuals in the sample population (Johnson, 2000). Low socioeconomic status, characterized by low income, low educational attainment, and low literacy levels increase the tendency to underreport energy intakes (Briefel et al. Ethnic differences affecting sensitivities and psychological perceptions relating to eating and body weight can also affect the accuracy of reported food intakes (Tomoyasu et al. Finally, individuals with infrequent symptoms of hunger under report to a greater degree than those who experience frequent hunger (Bathalon et al. Reported intakes of added sugars are also significantly lower than that consumed, due in part to the frequent omis sion of snack foods from 24-hour food recording (Poppitt et al. Clearly, it is no longer tenable to base energy requirements on self-reported food consumption data. Thus, mean expected energy require ments for different levels of physical activity were defined. However, there are recognized problems with the factorial method and doubts about the validity of energy requirement predictions based on it (Roberts et al. The first problem is that there are a wide range of activities and physical efforts performed during normal life, and it is not feasible to measure the energy cost of each. Another concern with the factorial method is that the measurement of the energy costs of specific activities imposes constraints (due to mechanical impediments associated with performing an activity while wearing unfamiliar equipment) that may alter the measured energy costs of different activities. Although generali zations are essential in trying to account for the energy costs of daily activi ties, substantial errors may be introduced. Also, and perhaps most importantly, the factorial method only takes into account activities that can be specifically accounted for. However, 24-hour room calorimeter studies have shown that a significant amount of energy is expended in spontaneous physical activities, some of which are part of a sedentary lifestyle (Ravussin et al. Thus, the factorial method is bound to underestimate usual energy needs (Durnin, 1990; Roberts et al. It was originally proposed and developed by Lifson for use in small animals (Lifson and McClintock, 1966; Lifson et al. Two stable isotopic forms of water (H 18O and 2H O) are 2 2 administered, and their disappearance rates from a body fluid. However, the measurements were obtained in men, women, and children whose ages, body weights, heights, and physi cal activities varied over wide ranges. At the present time, a few age groups are underrepresented and interpolations had to be performed in these cases. Indeed, overfeeding studies show that over eating is inevitably accompanied by substantial weight gain, and that reduced energy intake induces weight loss (Saltzman and Roberts, 1995). Bioimpedance data were used to calculate percent body fat using equa tions developed by Sun and coworkers (2003). Yet no correlation can be detected between height and percent body fat in men, whereas in women a negative correlation exists, but with a very small R2 value (0. Therefore, cutoff points to define underweight and overweight must be age and gender-specific. The revised growth charts for the United States were derived from five national health examination surveys collected from 1963 to 1994 (Kuczmarski et al. Childhood over weight is associated with several risk factors for later heart disease and other chronic diseases including hyperlipidemia, hyperinsulinemia, hyper tension, and early arteriosclerosis (Must and Strauss, 1999). Similarly, overweight has been defined as above the 97th percentile for weight-for length. For lengths between the 3rd and 97th percentiles, the median and range of weights defined by the 3rd and 97th weight-for-length percentiles for children 0 to 3 years of age are presented in Tables 5-6 (boys) and 5-7 (girls) (Kuczmarski et al. It is unlikely that body composition to any important extent affects energy expenditure at rest or the energy costs of physical activities among adults with body mass indexes from 18. In adults with higher percentages of body fat composition, mechanical hindrances can increase the energy expenditure associated with certain types of activity. Cross-sectionally, Goran and coworkers (1995a) and Griffiths and Payne (1976) reported significantly lower resting energy expenditure in children born to one or both overweight parents when the children were not themselves overweight. As such, these data are consis tent with the general view that obesity is a multifactor problem. The question of whether obese individuals may have decreased energy requirements after weight loss, a factor that would help explain the com mon phenomenon of weight regain following weight loss, has also been investigated. Notable exceptions to the latter conclusion are from studies of Amatruda and colleagues (1993) and Weinsier and colleagues (2000), which compared individuals longitudinally over the course of weight loss with a cross sectional, never-obese control group. The combination of these data from different types of studies does not permit any general conclusion at the current time, and further studies in this area are needed. Physical Activity the impact of physical activity on energy expenditure is discussed briefly here and in more detail in Chapter 12. Given that the basal oxygen (O2) consumption rate of adults is approximately 250 mL/min, and that athletes such as elite marathon runners can sustain O2 consumption rates of 5,000 mL/min, the scale of metabolic responses to exercise varies over a 20-fold range. The increase in energy expenditure elicited while physical activities take place accounts for the largest part of the effect of physical activity on overall energy expenditure, which is the product of the cost of particular activities and their duration (see Table 12-1 for examples of the energy cost of typical activities). Effect of Exercise on Postexercise Energy Expenditure In addition to the immediate energy cost of individual activities, physi cal activity also affects energy expenditure in the post-exercise period. Excess postexercise O2 consumption depends on exercise intensity and duration as well as other factors, such as environmental temperatures, state of hydration, and degree of trauma, demonstrable sometimes up to 24 hours after exercise (Bahr et al. In one study, residual effects of exercise could be seen following 15 hours of exercise, but not after 30 hours (Herring et al. There may also be chronic changes in energy expenditure associated with regular physical activity as a result of changes in body composition and alterations in the metabolic rate of muscle tissue, neuroendocrine status, and changes in spontaneous physical activity associated with altered levels of fitness (van Baak, 1999; Webber and Macdonald, 2000). However, the magnitude and direction of change in energy expenditure associated with these factors remain controversial due to the variable effects of exer cise on the coupling of oxidative phosphorylation in mitochondria, on ion shifts, on substrates, and on other factors (Gaesser and Brooks, 1984). Spontaneous Nonexercise Activity Spontaneous nonexercise activity has been reported to be quantita tively important, accounting for 100 to 700 kcal/d, even in subjects resid ing in a whole-body calorimeter chamber (Ravussin et al. Sitting without or with fidgeting raises energy expenditure by 4 or 54 percent respectively, compared to lying supine (Levine et al. This suggests that the subjects had lower levels of spontaneous movement after strenuous exercise because they were more tired. Similarly, Blaak and coworkers (1992) reported no measurable change in spontaneous physical activity in obese boys enrolled in an exercise-training program. The combination of these different results indicates that the effects of planned physical activity on activity at other times are highly variable (ranging from overall positive to negative effects on overall energy expen diture). This most likely depends on a number of factors, including the nature of the exercise (strenuous versus moderate), the initial fitness of the subjects, body composition, and gender. Gender There are substantial data on the effects of gender on energy expendi ture throughout the lifespan. Although the energy requirement for growth relative to mainte nance is low, except for the first months of life, satisfactory growth is a sensitive indicator of whether energy needs are being met. The energy cost of growth as a percentage of total energy requirements decreases from around 35 percent at 1 month to 3 percent at 12 months of age, and remains low until the pubertal growth spurt, at which time it increases to about 4 percent (Butte, 2000). Infants double their birth weight by 6 months of age, and triple it by 12 months (Butte et al. Progressive fat deposi tion in the early months results in a peak in the percentage body weight that is fat at 3 to 6 months (about 31 percent) and body fatness sub sequently declines to an average of 27 percent at 12 months (Butte et al. During infancy and childhood, girls grow slightly slower than boys, and girls have slightly more body fat (Butte et al. During adoles cence the gender differences in body composition are accentuated (Ellis, 1997; Ellis et al. Growth velocity is a sensitive indicator of energy status and use of growth velocity charts will detect growth faltering earlier than detected using attained growth charts. Problems with measurement precision and high variabil ity in individual growth rates over short time periods complicate the inter pretation of growth velocity data. The timing of the adolescent growth spurt, which typically lasts 2 to 3 years, is also very variable, with the onset typically between 10 and 13 years of age in the majority of children (Forbes, 1987; Tanner, 1955). In general, weight velocity reflects acute episodes of dietary intake, whereas length velocity is affected by chronic factors. The suggested breakpoint for a more rapid decline apparently occurs around 40 years of age in men and 50 years of age in women (Poehlman, 1992, 1993). All of these determinants of energy requirements are potentially influenced by genetic inheritance, with trans missible and nontransmissible cultural factors contributing to variability as well. Currently there is insufficient research data to predict differences in energy requirements among specific genetic groups, but as data accumu late this may become possible. The effects of genetic inheritance on body composition are well known, with most studies reporting that 25 to 50 percent of interindividual vari ability in body composition can be attributed to genetic factors (Bouchard and Perusse, 1993). The same group also reported that there is a genetic component to the weight gain response to 1,000 kcal/d of overfeeding (Bouchard et al. These studies are consistent with the reports of lower levels of reported physical activity in African-American versus Caucasian adults (Washburn et al. Other Ethnic Groups In addition to African Americans and Caucasians, other ethnic groups have been investigated for potential differences in energy requirements. Similarly, physical activity levels were not different between Pima Indian and Caucasian children (Salbe et al. Thus, there are currently insufficient data to define specific differences in energy requirements between different racial groups and more research is needed in this area. The question of whether normal variations in ambient temperature influence energy requirements is therefore complex. Ambient temperature effects are probably only significant when there is prolonged exposure to substantial cold or heat. The energy cost of work was judged to be 5 percent greater in a cold environment as com pared to a warm environment (Consolazio et al. There can also be an additional energy cost (2 to 5 percent) of both the increased weight of clothing worn and the hobbling effect of that clothing in cold weather compared with clothing worn in warm weather (Consolazio et al. In addition, temperatures low enough to induce shivering or increased muscular activity will increase energy needs because of the increase in mechanical work (Timmons et al. More recent work also suggests that the recognized increase in energy expenditure in markedly cold cli mates may be greater in physically active individuals than in sedentary ones (Armstrong, 1998). There is an increase in the energy expenditure of standard tasks when ambient temperatures are very high (Consolazio et al. However, this increase in energy expenditure may be attenuated by continued expo sure. More recent studies have reported a significant effect of variations in ambient temperature within the usual range on energy requirements. Instead, the effect of ambient temperature appears to be confined to the period of time during which the ambient temperature is altered. Nevertheless, the energy expenditure response to cold temperatures may be enhanced with previous acclimatization by pro longed exposure to a cool environment (Kashiwazaki et al. Since most of the recent data has been collected in women, further research in this area is needed. There was also no significant differ ence in season-related values for physical activity in free-living adult Dutch women, but in contrast to the values reported above for soldiers, the values tended to be higher in summer than in winter (van Staveren et al. For this reason, no specific allowance is made for ambient temperature in the requirements for energy. Altitude Hypoxia increases glucose utilization whether measurements are made on isolated muscle tissue (Cartee et al. Adaptation and Accommodation There are two key differences between nutritional adaptation and accommodation (Waterlow, 1999). First, while adaptation implies mainte nance of essentially unchanged functional capacity in spite of some alter ation in steady-state conditions, accommodation allows maintenance of adequate functional capacity under altered steady-state conditions. Second, whereas accommodation involves relatively short-term adjustments, such as the responses needed to maintain homeostasis, adaptation involves changes in body composition that occur over a more extended period of time. Adaptation the term adaptation describes the normal physiological responses of humans to different environmental conditions. A good example of adapta tion is the increase in hemoglobin concentration that occurs when indi viduals live at high altitudes (Leon-Velarde et al. Changes in energy intake or in energy expenditure trigger metabolic and behavioral responses aimed at restoring energy balance in adults.
