ObjectiveTo examine social network member characteristics associated with weight loss.MethodsCross-sectional examination of egocentric network data from 245 Black and Hispanic adults with BMI ≥ 25 kg/m2 enrolled in a small change weight loss study. The relationship between weight loss at 12 months and characteristics of helpful and harmful network members (relationship, contact frequency, living proximity and body size) were examined.ResultsThere were 2,571 network members identified. Mean weight loss was -4.8 (±11.3) lbs. among participants with network help and no harm with eating goals vs. +3.4 (±7.8) lbs. among participants with network harm alone. In a multivariable regression model, greater weight loss was associated with help from a child with eating goals (p=.0002) and coworker help with physical activity (p=.01). Weight gain was associated with having network members with obesity living in the home (p=.048) and increased network size (p=.002).ConclusionsThere was greater weight loss among participants with support from children and coworkers. Weight gain was associated with harmful network behaviors and having network members with obesity in the home. Incorporating child and co-worker support, and evaluating network harm and the body size of network members should be considered in future weight loss interventions.

This cost-effectiveness study comparing early versus standard antiretroviral treatment (ART) for HIV, based on randomized clinical trial data from Haiti, reveals that the new WHO guidelines for early ART initiation can be cost-effective in resource-poor settings.

BackgroundFaith-based organizations are recognized as an influential venue for behavioral health interventions. However, less is known about efficient approaches for identifying and recruiting these organizations and about the processes that enable successful partnership.Community ContextIn 2007, 66% of Latinos and 70% of blacks in New York City reported being overweight or obese. Project SCALE (Small Changes and Lasting Effects) is a 5-year randomized behavioral weight loss intervention trial aimed to help black and Latino adults lose weight by making small changes in eating behaviors and daily leisure physical activity. The study partnered with faith-based organizations.MethodsFaith-based organizations were identified primarily through direct referrals. Recruitment consisted of screening faith-based organizations, establishing a memorandum of understanding, and intervention modification. Partnership maintenance occurred primarily via progress meetings.OutcomesWe identified processes that supported and impeded study recruitment and retention. Obtaining leadership support and using group orientation sessions were successful recruitment and retention processes. A balance must be found between leadership, advocacy, and causing members to feel pressured to participate in the study.InterpretationBehavioral health interventions implemented in faith-based organizations can reduce health disparities. However, researchers must determine whether faith-based organizations have the capacity to partner in intensive interventions. Focusing on the establishment of strong partnerships at the onset will help ensure that mutual objectives are achieved and sustained long-term.
