Self-efficacy is a commonly examined cognitive determinant of behavior change in weight-loss trials, but there has been little uniformity in its measurement. To address this, a recently developed survey captures self-efficacy as it relates to three behavioral domains of interest to weight-loss interventionists: physical activity (PA), healthful eating, and weight loss. The purpose of this study was to test the psychometric properties of the Brief Weight-Loss-Related Behavior Self-Efficacy Scales in a large sample ( = 599) of adults with prediabetes.

Population health management (PHM) strategies to address diabetes prevention have the potential to engage large numbers of at-risk individuals in a short duration. We examined a PHM approach to recruit participants to a diabetes prevention clinical trial in a metropolitan health system. We examined reach and representativeness and assessed differences from active and passive respondents to recruitment outreach, and participants enrolled through two clinical screening protocols.

The implementation of evidence-based physical activity interventions is improved when integrated research-practice partnerships are used. These partnerships consider both research- and practice-based evidence that moves beyond only assessing program efficacy. Our novel hypothesis is that integrated research-practice partnerships may lead to interventions that are practical and effective, reach more participants, and are more likely to be sustained in practice.

This study aimed to evaluate the effectiveness of the VAMOS strategy (Health-Improving Active Life) in improving physical activity (PA), dietary habits, and anthropometric variables of primary health care (PHC) users in Brazil. A randomized controlled community trial was conducted at two units of the Health Academy Program (HAP; a service provided by PHC), which were randomly assigned either to control group (CG) or intervention group (IG). Participants in both groups (CG = 156 and IG = 135) took part in physical activity classes provided by HAP facilities with those in IG also participating in the VAMOS strategy for 12 weeks.

Excessive adiposity (particularly visceral fat mass) increases the risks of developing metabolic syndrome. Women have lower deposit of visceral fat than men, and this pattern becomes diminished postmenopausally, but the underlying mechanism remains largely unknown. Here, we show that the gender difference in visceral fat distribution is controlled by an estradiol-autophagy axis.

This study assessed the lifetime health and economic consequences of an efficacious scalable community weight loss program for overweight and obese adults. We applied a state-transition Markov model to project lifetime economic outcome (US dollar) and the degree of disease averted as a result of a weight loss intervention, compared with no intervention, from a payer perspective. Effect sizes of the intervention on weight loss, by sex, race and ethnicity, and body mass index (BMI) of participants, were derived from a 12-month community program.

Self-efficacy is a commonly included cognitive variable in weight-loss trials, but there is little uniformity in its measurement. Weight-loss trials frequently focus on physical activity (PA) and eating behavior, as well as weight loss, but no survey is available that offers reliable measurement of self-efficacy as it relates to each of these targeted outcomes. The purpose of this study was to test the psychometric properties of brief, pragmatic self-efficacy scales specific to PA, healthful eating and weight-loss (4 items each).
