ABSTRACT

BACKGROUND: Personalizing approaches to prevention and treatment of obesity will be a crucial aspect of precision health initiatives. However, in considering individual susceptibility to obesity, much remains to be learned about how to support healthy weight management in different population subgroups, environments and geographical locations.

SUBJECTS/METHODS: The International Weight Control Registry (IWCR) has been launched to facilitate a deeper and broader understanding of the spectrum of factors contributing to success and challenges in weight loss and weight loss maintenance in individuals and across population groups. The IWCR registry aims to recruit, enroll and follow a diverse cohort of adults with varying rates of success in weight management. Data collection methods include questionnaires of demographic variables, weight history, and behavioral, cultural, economic, psychological, and environmental domains. A subset of participants will provide objective measures of physical activity, weight, and body composition along with detailed reports of dietary intake. Lastly, participants will be able to provide qualitative information in an unstructured format on additional topics they feel are relevant, and environmental data will be obtained from public sources based on participant zip code.

CONCLUSIONS: The IWCR will be a resource for researchers to inform improvements in interventions for weight loss and weight loss maintenance in different countries, and to examine environmental and policy-level factors that affect weight management in different population groups. This large scale, multi-level approach aims to inform efforts to reduce the prevalence of obesity worldwide and its associated comorbidities and economic impacts.

ABSTRACT

BACKGROUND: The purpose of this study is to examine three-factor eating questionnaire (TFEQ) scores at baseline and post-intervention (6 months) on successful weight loss and weight maintenance in an 18-month behavioral weight management intervention for adults with overweight and obesity.

METHODS: TFEQ and weight were assessed at baseline, 6, and 18 months. Logistic regression models were used to examine scores at baseline on disinhibition, restraint, and perceived hunger factors in the TFEQ on 5% body weight loss at 6 months and 6-month scores to predict 5% weight maintenance at 18 months while controlling for age, sex, and baseline weight.

RESULTS: Participants (n = 287; age = 43.8 ± 10.36 years; female = 64.1%; weight = 222.5 ± 39.02 pounds; BMI = 34.73 ± 4.56) were included for analysis. Dietary restraint at baseline was the only significant predictor of 5% weight loss at 6 months. None of the TFEQ subscale scores at 6 months predicted 5% weight maintenance at 18 months. The model examining weight loss at 6 months accounted for 7% of the variance of the outcome and 11% of the variance of weight maintenance at 18 months.

CONCLUSION: Dietary restraint is a unique eating behavior associated with weight loss at 6 months beyond other eating behaviors measured by the TFEQ in an adult sample enrolled in a weight loss intervention. No other subscale scores were significant at 6 months or at 18 months. Future research should consider how to promote flexible control and discourage adoption of rigid restraint behaviors since the latter is associated with disordered eating patterns.

ABSTRACT

The purpose of this study was to assess impact of different volumes of exercise as well as cumulative moderate to vigorous PA (MVPA), on energy intake and diet quality, as assessed by the Healthy Eating Index 2010 (HEI-2010), across a 12-month weight maintenance intervention. Participants were asked to attend group behavioral sessions, eat a diet designed for weight maintenance, and exercise either 150, 225, or 300 mins/week. Dietary intake was assessed by 3-day food records, and MVPA was assessed by accelerometry. Two hundred and twenty-four participants (42.5 years of age, 82% female) provided valid dietary data for at least one time point. There was no evidence of group differences in energy intake, total HEI-2010 score, or any of the HEI-2010 component scores (all p > 0.05). After adjusting for age, sex, time, group, and group-by-time interactions there was an effect of cumulative MVPA on energy intake (1.08, p = 0.04), total HEI-2010 scores (-0.02, p = 0.003), sodium (-0.006, p = 0.002) and empty calorie scores (-0.007, p = 0.004. There was evidence of a small relationship between cumulative daily EI and weight (β: 0.00187 95% CI 0.001, p= 0.003). However, there was no evidence for a relationship between HEI total score (β: -0.006, 95% CI -0.07-0.06) or component scores (all p > 0.05) and change in weight across time. The results of this study suggests that increased cumulative MVPA is associated with small, clinically insignificant, increases in energy intake and decreases in HEI scores.
