BACKGROUND/OBJECTIVES: Existing evidence on lifestyle modification programs for weight loss is limited by the high attrition rate of such programs. Identifying predictors of adherence to a lifestyle modification program could result in program improvement. However, little is known about behavior-specific adherence and its psychological predictors. This study aimed to examine the psychological predictors of adherence after one-month participation in a community-based lifestyle modification program among Chinese overweight and obese adults in Hong Kong. SUBJECTS/METHODS: A total of 205 Chinese overweight and obese adults aged $38.9{\pm}10.5years$ completed the study. Data were collected at baseline and after one month using self-reported questionnaires, which assessed knowledge (self-developed scale), motivation (Treatment Self-Regulation Questionnaire), stage of change (Stage of Exercise Scale) and self-efficacy (Self-Rated Abilities for Health Practices Scale). At one month, a 4-day dietary recall and the International Physical Activity Questionnaire-Short Form were used to assess dietary and physical activity (PA) adherence. Food and PA diaries were examined to indicate self-monitoring. Program attendance was tracked between baseline and one-month follow-up. RESULTS: After one month, participants reported high dietary adherence, attendance, and adherence to self-monitoring but low PA adherence. Multiple regression analyses suggested that diet self-efficacy (baseline) and nutrition knowledge (one-month change) were independent predictors of dietary adherence score at one month, whereas autonomous PA motivation (baseline) and PA self-efficacy (both baseline and one-month change) were independent predictors of PA adherence score at one month. No significant psychological predictor was identified for attendance or self-monitoring. CONCLUSIONS: The results suggest that the effect of psychological factors on adherence differs between diet and PA adherence outcomes. To promote adherence, practitioners should assess self-efficacy, knowledge, and motivation at the beginning of a weight-loss program and explore behavior-specific strategies to improve knowledge and self-efficacy. The results of this study have direct implications for program improvements.

운동과 식이요법을 병행한 체중감량 프로그램에 참여한 여성 비만인의 체지방량, 안정시대사량, 그리고 갑상선 호르몬 차이를 비교할 목적으로 실험한 결과, 체지방량, 체지방율, 체표면적이 유의하게 감소되었고, 안정시대사량 예측치와 실측치 모두 유의하게 감소되었지만, 갑상선 호르몬의 변화는 나타나지 않았다. 안정시대사량과 신체요인들과의 상관분석 결과, 제지방 체충이 가장 밀접한 관계를 보였으며, 안정시대사량과 갑상선 호르몬들과의 관계에서는 TSH와 가장 밀접한 관계를 나타내었다. 결론적으로 8주간 체중감량 프로그램 참여로 체지방은 효과적으로 감소되었으나, 갑상선 호르몬 차이는 없었고 체중감소에 비해 제지방이 유지됨으로써 안정시대사량의 감소는 최소화되어, 에너지 대사작용에 긍정적인 영향을 준 것으로 사료된다.

BACKGROUND/OBJECTIVES: The objectives were to investigate the effect of a 12-wk intervention with behavioral modification on clinical characteristics and dietary intakes of young and otherwise healthy obese and to identify factors for successful weight loss. The goal was to lose 0.5 kg per week by reducing 300-500 kcal/day and by increasing physical activities. SUBJECTS AND METHODS: Forty four obese subjects (BMI > 25) and 19 normal weight subjects (BMI 18.5-23) finished the 12-week intervention. Obese subjects participated in 5 group educations and 6 individual counseling sessions. Normal weight subjects attended 6 individual counseling sessions for evaluations of dietary intake and exercise pattern. Anthropometric and clinical characteristics and 3-day dietary records were evaluated at baseline and week12. RESULTS: Weight and serum triglyceride and free fatty acid concentrations in obese group decreased significantly with intervention. Intakes of energy, fat, and cholesterol decreased significantly in the obese. Active participation, realistic weight loss goal setting, and weight gain after high school graduation not during childhood were identified as key factors for successful weight loss. CONCLUSIONS: The 12-week intervention with behavioral modification resulted in reduced energy and fat intakes and led to significant weight loss and improvements of clinical characteristics in the obese. The finding that those who became obese during childhood lost less weight indicates the importance of 'early' intervention.

Purpose: Obesity is the major risk factor of the heart disease and the metabolic disease. And many obese women have dysfunction of the endocrine system. There are many reports about oriental obesity treatment program. In clinics, the electroacupuncture with exercise is believed more effective. But the difference of weight loss as exercise and women was not studied. Methods: The subjects were 75 young women who visited Kangnam Kyunghee hospital for obesity management from March 2006 to July 2008. Six treatments had performed, the weight loss checked at every treatment. 52 women treated by oriental obesity treatment with exercise, 23 women treated therapy without exercise. As the exercise and the age, the weight loss was compared. Results: The weight loss of electroacupuncture with exercise was higher than that of electroacupuncture without exercise, but was not significant. The weight loss of perimenopausal women was significantly low. Conclusion: The comparison of electroacupuncture with exercise and electroacupuncture without exercise was not significantly different. The weight loss of the older women would be less than the weight loss of the younger.

The purpose of the study was to develop an internet nutritional counseling program using an expert system to assist obese people to lose weight through behavior modification. The internet counseling program for weight loss was developed by the accumulation of knowledge dealing with eating habits and exercising behaviors in expert system tool, Knowledge Engineering Agent (KEA) by a dietitian without any help of computer expert. To accumulate knowledge into KEA, survey was performed in 150 obese people, dietitians reviewed and consulted each survey case, and the consulted contents were learned and accumulated into KEA. Survey questionnaire was the same as that of the internet consulting program, and it included general characteristics, dietary habits, lifestyle, and exercise patterns related to obesity. Also, the dietitian selected proper factors inferred from the survey questionnaire of each case, and added the conclusions for them. Conclusions were made for helping clients to correct bad eating behaviors and accumulate good behaviors to lose weight. Counseling was divided into two parts; a two-week part and a daily part. Two-week counseling was performed based on 4 step questionnaires, and daily counseling was done for daily food consumption and physical activity. When clients answered survey questionnaires in a counseling internet program, the recommendations on how to eat, to exercise and to deal with stress in a real time for each case, was given. In conclusion, a counseling internet program for weight reduction can be used to give advices how to deal with obesity in a man-to-man way in a real time using KEA where nutritional knowledge based on behavior modification for weight loss was accumulated.

Background: In a cluster-randomized trial, the Safety and Health Involvement For Truck drivers intervention produced statistically significant and medically meaningful weight loss at 6 months (-3.31 kg between-group difference). The current manuscript evaluates the relative impact of intervention components on study outcomes among participants in the intervention condition who reported for a post-intervention health assessment (n = 134) to encourage the adoption of effective tactics and inform future replications, tailoring, and enhancements. Methods: The Safety and Health Involvement For Truck drivers intervention was implemented in a Web-based computer and smartphone-accessible format and included a group weight loss competition and body weight and behavioral self-monitoring with feedback, computer-based training, and motivational interviewing. Indices were calculated to reflect engagement patterns for these components, and generalized linear models quantified predictive relationships between participation in intervention components and outcomes. Results: Participants who completed the full program-defined dose of the intervention had significantly greater weight loss than those who did not. Behavioral self-monitoring, computer-based training, and health coaching were significant predictors of dietary changes, whereas behavioral and body weight self-monitoring was the only significant predictor of changes in physical activity. Behavioral and body weight self-monitoring was the strongest predictor of weight loss. Conclusion: Web-based self-monitoring of body weight and health behaviors was a particularly impactful tactic in our mobile health intervention. Findings advance the science of behavior change in mobile health intervention delivery and inform the development of health programs for dispersed populations.

The purpose of this study was to evaluate the multilateral weight control program provided by the university health care center for female college students. The program was 8weeks long and composed of nutrition consultation, exercise, and behavior modification. Nutrition education focused on a low calorie and balanced diet, increasing the intake of protein and micronutrients and reducing carbohydrate and fat consumption. Evaluations were made upon completion of an 8-week program and upon follow-up at 6 months after the end of program. A total of 92 women completed the 8-week program, while 20 completed the follow-up survey. Upon completion of the 8-week program, significant decreases in body weight, BMI, body fat (kg), and %body fat were observed, and muscle mass was also reduced. The total energy and carbohydrates intake were also significantly decreased in subjects with weight loss, while the percentage of subjects whose consumption of protein, calcium, iron, vitamin $B_1$, $B_6$, and niacin did not meet the EAR, were decreased. The blood values of glucose, total cholesterol and HDL-cholesterol were decreased. The follow-up survey revealed that the subjects continued to lose weight after completion of the program. In addition, a Mini nutrition assessment revealed that diet quality improved, especially with respect to reductions in the consumption frequency of fried, greasy and salty food. In conclusion, the multilateral weight control program with diet education for female college students was effective for long lasting weight control and improved dietary behavior. Nutrition education for weight reduction should focus on balanced nutrition as well as lowering the total caloric intake.

Purpose: This study was to verify the effects of infant massage on weight recovery from physiologic weight loss, physical development of infants, and identity of their mothers. Method: A study with quasi-experimental design with time delay method was conducted from October 20, 2004 through February 20, 2005 with mothers and infants recruited from postpartum care center. 20 infants in the experimental group (once a day massage group) and 22 control group remained for the final analysis. Data were analyzed using SPSS win 11.0 program by frequency, percentage, mean, standard deviation, t-test and $X^2-test$. Results: There was no significant group difference in weight recovery from physiologic weight loss. However, experiment group showed significant increase in weight and chest circumference in 4 weeks after birth compare to the control group. For changes in behavior, experimental group showed more positive behavioral changes. The mothers who conducted massage for their infants showed higher score of identity as mothers. Conclusion: Since massage applied once a day can be still effective on physical growth of the infants, massage training program for mothers should be developed to apply easily for their infants at home. Further study is suggested to identify influencing factors on performed by mothers and identity as mothers.
