Individualizing recommendations for weight management in the elderly.

PURPOSE OF REVIEW: This review provides current strategies for weight management in the elderly population as it can be different from young adults due to multiple factors: co-morbidities, polypharmacy, limitation of functional activities, social issues. RECENT FINDINGS: The recommendations for weight management for all age groups include exercise, diet, pharmacotherapy and surgery. In the elderly population, because of changes in age-related body composition, reduced energy requirement and expenditure, the standard young adult recommendations cannot be applied directly. The goal of weight management in the elderly differs from the young adult. The preferred method is maintenance of weight rather than aggressive weight loss with achieving a healthy, functional, and good quality of life. SUMMARY: The growing prevalence of obesity in the elderly population is becoming a major health problem and can affect functional status, can contribute to frailty and decline in activity, as well as worsening co-morbid medical problems. Practical recommendations for weight management in the elderly are challenging because of the obesity paradox in the elderly, and the lack of substantial research in this population. Individualized recommendations should be considered for elderly patients with a focus on the underlying medical problems, functional status and living environments.

Medical nutrition: a comprehensive, school-wide curriculum review.

BACKGROUND: A school-wide nutrition program was established in 1982 and a required medical nutrition course (MNC) was established in 1985 at the University of Nevada School of Medicine. Emphasis was placed on developing an integrated curriculum and on using innovative methods to incorporate nutrition into the existing curriculum. OBJECTIVE: The objective of this review was to establish a baseline and make positive curricular changes to comply with the recommendations of the Liaison Committee on Medical Education for accreditation. The MNC and the nutrition curriculum were evaluated as part of this 3-y comprehensive, school-wide evaluation process. DESIGN: The MNC was invited for review (December 2004) because of its position in the curriculum (first year), special content and methods, and relation to other courses. A review team, which consisted of the Assistant Dean for Medical Education (who chaired the team), a curriculum coordinator, faculty representatives, and a medical student, was appointed. The MNC coordinator prepared a review book that included the requested documentation. The initial 3-h review meeting culminated in a formal evaluation and recommendations. Follow-up meetings at 1 mo and 1 y were scheduled. RESULTS: The review was a positive process that reaffirmed the uniqueness of the nutrition program at the University. It supported the MNC as an important part of the required curriculum. Recommendations included use of the Web, encouragement to identify new opportunities with interested faculty, and a structure to further integrate and align nutrition into existing courses. CONCLUSIONS: A positive, proactive review process supports the importance of nutrition in the medical school curriculum and encourages further integration.

Do somatic complaints predict subsequent symptoms of depression?

BACKGROUND: Evidence suggests substantial comorbidity between symptoms of somatization and depression in clinical as well as nonclinical populations. However, as most existing research has been retrospective or cross-sectional in design, very little is known about the specific nature of this relationship. In particular, it is unclear whether somatic complaints may heighten the risk for the subsequent development of depressive symptoms. METHODS: We report findings on the link between symptoms of somatization (assessed using the SCL-90-R) and depression 5 years later (assessed using the CES-D) in an initially healthy cohort of community adults, based on prospective data from the RENO Diet-Heart Study. RESULTS: Gender-stratified multiple regression analyses revealed that baseline CES-D scores were the best predictors of subsequent depressive symptoms for men and women. Baseline scores on the SCL-90-R somatization subscale significantly predicted subsequent self-reported symptoms of depressed mood 5 years later, but only in women. However, somatic complaints were a somewhat less powerful predictor than income and age. CONCLUSIONS: Our findings suggest that somatic complaints may represent one, but not necessarily the most important, risk factor for the subsequent development of depressive symptoms in women in nonclinical populations. The results also highlight the importance of including social variables in studies on women's depression as well as conducting additional research to further examine predictors of depressive symptoms in men.

Differences between estimated caloric requirements and self-reported caloric intake in the women's health initiative.

PURPOSE: To compare energy intake derived from a food frequency questionnaire (FFQ) with estimated energy expenditure in postmenopausal women participating in a large clinical study. METHODS: A total of 161,856 women aged 50 to 79 years enrolled in the Women's Health Initiative (WHI) Observational Study (OS) or Clinical Trial (CT) [including the Diet Modification (DM) component] completed the WHI FFQ, from which energy intake (FFQEI) was derived. Population-adjusted total energy expenditure (PATEE) was calculated according to the Harris-Benedict equation weighted by caloric intakes derived from the National Health and Nutrition Examination Survey. Stepwise regression was used to examine the influence of independent variables (e.g., demographic, anthropometric) on FFQEI-PATEE. Race, region, and education were forced into the model; other variables were retained if they increased model explanatory ability by more than 1%. RESULTS: On average, FFQEI was approximately 25% lower than PATEE. Regression results (intercept=-799 kcal/d) indicated that body mass index (b=-23 kcal/day/kg.m(-2)); age (b=15 kcal/day/year of age); and study arm (relative to women in the OS, for DM women b=169 kcal/d, indicating better agreement with PATEE) increased model partial R(2)>.01. Results for CT women not eligible for DM were similar to those of women in the OS (b=14 kcal/d). There also were apparent differences by race (b=-152 kcal/d in Blacks) and education (b=-67 kcal/d in women with

Medical nutrition therapy for the treatment of obesity.

Most physicians do not have the benefit of in-house registered dietitians to facilitate patient evaluation and create treatment plans. Fortunately, with the new tools that are available to physicians and patients, energy balance can be evaluated. Then, a balanced deficit diet can be encouraged to achieve a weight management goal while maintaining healthy food intake patterns. Patients should also be counseled regarding weight maintenance diets to prevent weight gain. A low-fat diet is preferred because the patient will benefit from improved cardiac risk as a result of weight loss and a restricted saturated fat content is healthier. Other diets and approaches are acceptable if they are hypocaloric and do not negatively impact the patient's health (eg, some high-protein, high-fat diets can increase lipid levels; high-carbohydrate diets can increase triglycerides in patients who have type 2 diabetes). As patients lose weight, further increases in physical activity and exercise should be emphasized to help maintain lost weight. It is also helpful from a behavioral perspective to encourage patients to monitor their weight, food intake, and physical activity. Medical offices can support patients by providing weekly or biweekly weigh-ins to track progress and provide ongoing feedback. Patients should be reminded that the ultimate goal of any weight management program is gradual, incremental weight losses that are maintained over time. Sustainable and enjoyable changes in eating practices and physical activity patterns must be made along with a lifelong commitment to health.
