Results of a Family-Based Intervention Promoting Healthy Weight Strategies in Overweight Hispanic Adolescents and Parents: An RCT.
Hispanic adolescents in the U.S. are disproportionately affected by overweight and obesity compared with their White, non-Hispanic counterparts. This study examines the efficacy of an evidence-based family intervention adapted to target obesity-related outcomes among Hispanic adolescents who were overweight/obese compared with prevention as usual. ⋯ This intervention was not effective in improving overweight/obesity-related outcomes in adolescents. The intervention was effective in improving parents' dietary intake and BMI; however, the effects were not sustained in the long term. Other intervention strategies (e.g., booster sessions, increased nutritional information) may be necessary to sustain beneficial effects and extend effects to adolescent participants.

Improving Colorectal Cancer Screening in a Rural Setting: A Randomized Study.
Colorectal cancer screening has been shown to prevent or detect early colorectal cancer and reduce mortality; yet, adherence to screening recommendations remains low, particularly in rural settings. ⋯ A mailed motivational messaging letter with a low-cost screening alternative increased colorectal cancer screening in this largely rural community with generally poor adherence to screening recommendations. Mailed colorectal cancer screening reminders using motivational messaging may be an effective method for increasing screening and reducing rural colorectal cancer disparities.

Assessing an App-Based Child Restraint System Use Intervention in China: An RCT.
While child restraint systems are effective in protecting children from crash-related injuries and deaths, their use in China is extremely low. This study assessed the effectiveness of child restraint system education with and without behavioral skills training on improved use and explored participants' views regarding content and delivery of an onsite intervention and online (WeChat) boosters. ⋯ An education intervention was effective in improving parents' knowledge, attitude, and practice of child restraint system use. A social media intervention booster (WeChat) may provide a new channel to help promote child passenger safety in China.

Adding Financial Incentives to Online Group-Based Behavioral Weight Control: An RCT.
Internet-delivered behavioral weight control is promising for expanding the reach and availability of weight management, but online programs produce lower weight losses than typically achieved in person. Financial incentives have been shown to increase weight losses. This study examined whether adding financial incentives for self-monitoring and achieving target weight losses increases weight losses attained in a fully online, group-based behavioral weight management program compared with the same program alone. ⋯ Adding financial incentives to a program delivered fully online increases weight losses compared with the program alone and can achieve weight losses comparable to in-person programs, offering potential for substantial geographic reach.

Randomized Trial of a Physical Activity Intervention for Latino Men: Activo.
Latino men experience disproportionately high rates of diseases related to low physical activity, yet they are poorly represented in physical activity intervention trials. Efforts to promote physical activity in Latina women show promising results, yet such interventions are yet to be extended to Latino men. This study tested a computer expert system‒tailored, text messaging-supported physical activity intervention for underactive Spanish-speaking Latino men compared with a control group matched for contact time. Potential predictors of intervention success were also explored. ⋯ Findings suggest that an individually tailored intervention can successfully increase moderate to vigorous physical activity in underactive Latino men. Such technology-supported interventions have the potential for broad dissemination.
