Randomized Controlled Trial
Social media-delivered sexual health intervention: a cluster randomized controlled trial.
Youth are using social media regularly and represent a group facing substantial risk for sexually transmitted infection (STI). Although there is evidence that the Internet can be used effectively in supporting healthy sexual behavior, this has not yet extended to social networking sites. ⋯ Social networking sites may be venues for efficacious health education interventions. More work is needed to understand what elements of social media are compelling, how network membership influences effects, and whether linking social media to clinical and social services can be beneficial.

Randomized Controlled Trial Multicenter Study
Family history assessment: impact on disease risk perceptions.
Family Healthware™, a tool developed by the CDC, is a self-administered web-based family history tool that assesses familial risk for six diseases (coronary heart disease; stroke; diabetes; and colon, breast, and ovarian cancers) and provides personalized prevention messages based on risk. The Family Healthware Impact Trial (FHITr) set out to examine the clinical utility of presenting personalized preventive messages tailored to family history risk for improving health behaviors. ⋯ Family Healthware was effective at increasing disease risk perceptions, particularly for metabolic conditions, among those who underestimated their risk. Results from this study also demonstrate the relatively resistant nature of risk perceptions.

Mailed intervention to promote sun protection of children: a randomized controlled trial.
Sun exposure, especially during childhood, is the most important preventable risk factor for skin cancer, yet few effective interventions to reduce exposure exist. ⋯ The level of behavior change associated with this single-modality intervention is not likely sufficient to reduce skin cancer risk. However, the intervention shows promise for inclusion in longer-term, multicomponent interventions that have sufficient intensity to affect skin cancer incidence.

Randomized Controlled Trial Comparative Study
Facts up front versus traffic light food labels: a randomized controlled trial.
The U.S. food and beverage industry recently released a new front-of-package nutrition labeling system called Facts Up Front that will be used on thousands of food products. ⋯ Overall, those in the Traffic Light+ condition performed better than those in the Facts Up Front conditions on measures of nutrition knowledge and label perceptions.

Randomized Controlled Trial
Using mHealth technology to enhance self-monitoring for weight loss: a randomized trial.
Self-monitoring for weight loss has traditionally been performed with paper diaries. Technologic advances could reduce the burden of self-monitoring and provide feedback to enhance adherence. ⋯ PDA+FB use resulted in a small weight loss at 24 months; PDA use resulted in greater adherence to dietary self-monitoring over time. However, for sustained weight loss, adherence to self-monitoring is more important than the method used to self-monitor. A daily feedback message delivered remotely enhanced adherence and improved weight loss, which suggests that technology can play a role in improving weight loss.
