ABSTRACT TEXT: Obesity has reached epidemic proportions at all age levels in the US population. It is well known that excess adiposity is a many faceted illness that requires an individualized multidisciplinary approach. The new, safer anorectic pharmaceuticals for weight loss allow additional treatment options for the clinician, This study examined the impact of nutritional counseling by a registered dietitian (RD) in physiciansponsored weight loss programs that used anorectic aids. Fifty obese females (mean BMI = 34.1) between the ages of 18 and 65 were selfselected to receive medication nutrition, behavioral, and exercise counseling by a RD (n = 23) or pharmacotherapy alone (n = 27) over a period of nine months. Medication was monotherapeutic, however the physician prescribed a variety of anorectie aids that were evenly distributed between groups. Both groups attained a weight loss of greater than 10% from baseline, a change that is considered suecessful. However the mean decrease in BMI for the medication plus RD group (4.7 kg/m2) was not statistically different fi'om that in the medieation only group (5.2 kg/m2). Since the groups were self-selecting, clients may have chosen the treatment plan that best met their needs. RDs should continue to advocate for inclusion on weight management mnlfidisciplinary teams. TITLE: SELF-EFFICACY AND QUALITY-OF-LIFE IN OBESITY: ROLES OF DIET COUNSELING AND DEGREE OF WEIGHT LOSS. AUTHORS: KJ Melanson, J DeU'Olio, MR Carpenter, DP Berlin, SJ Knipe, KJ McInnis, J/vl Rippe. RippeLifestylelnstitute, 21 N. QuinsigamondAve, ShrewsburyMA 01545 USA. LEARNING OUTCOME: Identify relationships among changes in body composition, quality-of-lifeand weight loss self-efficacyin obese adults over a 12-week exercise intervention with and without dietary counseling. ABSTRACT TEXT: Increased physical activity and dietary modification improve body composition, but their inter-relationships wkh quallty-of-life and weight loss self-efficacyin obese adults remain uncertain. We enrolled 53 obese (body mass index (BMi)=31.4+2.9 kg/m2; x+sd) aduks (43.1+5.6 years) who completed a 12-weekwalking program with (D+EX; n=28) or without 0SX; n-25) diet modification. Subjects were counseled weekly by an exercise physiologist, and the D + EX group also met weekly with a dietitian. Diets were tailored to induce a 500 kcal/day deficit, averaging 50% carbohydrate, 25% fat and 25% pr9tein. At weeks 0 and 12, dietary data, fitness tests, and questionnaires (Profile of Mood States (POMS), Medical Outcome Study Short Form (SF-36) and the Weight Efficacy Lifestyle questionnaire (WEL)) were obtained. Body composition was analyzed by air displacement plethysmography. Body weight, BMI, waist circumference, fat mass and % body fat decreased more in the D + EX group than the EX group (p < 0.0001). POMS scores revealed decreases in tension and depression (both, p = 0.03), and increases in vigor (p =0.001) in the D+EX group but not the EX group. SF36 vkality scores (p=0.044) and total WEL scores (p=0.0158) showed greater improvements in the D+EX group than the EX group. For all subjects combined, changes in body fat, body weight and BMI were inversely related to every situational variable on the WEL (p ~0.0001-0.03), indicating significant increases in self-efficacywith weight reduction. However, baseline self-efficacywas not predictive of subsequent weight loss. In conclusion, dietary counseling and degree of weight loss may contribute to improvements in self-efficacy. Therefore, enhancing self-efficacyshould be considered important in weight loss counseling. (FundingSource:Pharmanex, Inc.)
LEARNING OUTCOME: To recognize discrepancies among individuals in reporting intake by the 24-hour recall method ABSTRACT TEXT: Two-hundred eight low-income females were assessed for food intake patterns and anthropometric measures to compare reported energy intakes with recommended energy intakes and to determine the relationship between energy intake and body mass index (BMI) and percent body fat. Food intake data were obtained using a 24hour recall administered by a registered dietitian. Mean age of the participants was 34 + 12 years and ranged from 18 to 81. Mean height was 161.5 _+6.9 cm and mean weight was 83.6 + 30.7 kg. BMI was calculated from height and weight data; mean BMI was 31.5 + 9.7. Percent body fat was determined using the Brozek formula from thigh, triceps, and iliac crest skinfold measurements. Mean percent body fat was 32.7 _+8.5. Individuals' reported intakes were categorized into one of three categories depending on whether they consumed the recommended amount of energy +_100 kcal or consumed fewer than 100 kcal below or greater than 100 kcal above their energy recommendations. An ANOVA was used to determine differences among groups and an alpha level of 0.05 was used to establish significance. Significant differences between reported intake and recommendations were found for the groups lhat either under or over reported energy intake (1282 + 418 vs 2102 + 401 and 2766 + 581 vs 1953 + 319, respectively). In addition, BMI and percent body fat were sorted based on energy intake categories. Individuals in the category reporting 100 or more fewer Kcals than recommended had significantly higher BMI (33.5 + 0.8) and percent body fat (34.1 + 0.7) than individuals in the other two groups. Based on these data it appears that overweight females tend to underreport their intake or have an unrealistic perception of the amount and type of food consumed. To assess intake in overweight females, a detailed food diary may be preferable to the 24-hour recall.

LEARNING OUTCOME: To increase the awareness of efficacy of Internet Hased weight reduction programs. ABSTRACT TEXT: The Intemet is widely becoming recognized as an important weight reduction tool. iVillage.com, a large site devoted to women's issues, conducted a six-week free weight loss "Lose it for Good" challenge. The program included three meal plans developed by a Registered Dietitian, three fitness plans developed by an exercise physiologist fitness expert, and daily motivational pep talks from a diet and body image psychologist. The Lose it for Good challenge included quizzes to help participants choose a meal and exercise plan, message boards for support and information, three on-line live chats with each expert, daily motivational pep talks, three participants who acted as Diary Keepers who shared their personal weight history and weekly updates on their experiences during the challenge, and a goal tracker that allows participants to keep track of the pounds and inches they lose as well as energy levels. 32,548 people participated in the challenge, losing a total of 6,977 pounds and 3,294 inches during the six-week program. Due to the popularity and success of this challenge, the meal planning, fitness, motivational information, transcripts of live chats, and message boards remain active elements on the website. As of March 31,2001, participants lost a total of 8,542 pounds and 4,001 inches. This project helps meet the information and support needs of large numbers of people who might not have access to reliable sources of weight loss information, and highlights areas where nutrition professionals can become involved as integral components of Intemet-based weight loss programs.
