Randomized Controlled Trial Multicenter Study
Cluster Randomized Trial for Hypertension Control: Effect on Lifestyles and Body Weight.
Lifestyle modification, such as healthy diet habits, regular physical activity, and maintaining a normal body weight, must be prescribed to all hypertensive individuals. This study aims to test whether a multicomponent intervention is effective in improving lifestyle and body weight among low-income families. ⋯ The multicomponent intervention was effective for increasing fruit and vegetable intake and physical activity with no effect on alcohol consumption, smoking, addition of salt, or body weight among low-income families in Argentina.

Randomized Controlled Trial
Randomized Trial of Low-Nicotine Cigarettes and Transdermal Nicotine.
A mandated reduction in the nicotine content of cigarettes may decrease smoking, but also increase demand for other nicotine products. The present study tested the impact of smoking cigarettes with very low nicotine content and concurrent use of a transdermal nicotine patch. ⋯ A mandated reduction in the nicotine content of cigarettes is likely to reduce the number of cigarettes smoked per day, but the added benefit of concurrent transdermal nicotine is unclear. Future studies should investigate whether alternative sources of noncombusted tobacco, such as e-cigarettes, enhance the effects of very low nicotine content cigarettes on smoking.

Randomized Controlled Trial
Impact of Brief Nicotine Messaging on Nicotine-Related Beliefs in a U.S. Sample.
The current study pilot tested the effect of a single, brief exposure to nicotine education messages on beliefs about nicotine, nicotine-replacement therapy (NRT), E-cigarettes, and cigarettes with reduced nicotine content (RNC). ⋯ Findings from the current study support the hypothesis that a brief nicotine messaging intervention-similar to the messages likely to be seen on warning labels or in media campaigns-is likely to correct misperceptions of nicotine, NRT, E-cigarettes, and RNC cigarettes.

Randomized Controlled Trial
Efficacy of an m-Health Physical Activity and Sleep Health Intervention for Adults: A Randomized Waitlist-Controlled Trial.
Interventions that improve both physical activity and sleep quality may be more effective in improving overall health. The purpose of the Synergy Study is to test the efficacy of a mobile health combined behavior intervention targeting physical activity and sleep quality. ⋯ This remotely delivered intervention did not produce statistically significant between-group differences in minutes of moderate-to-vigorous intensity physical activity. Significant short-term differences in resistance training and short- and medium-term differences in sleep health in favor of the intervention were observed.

Randomized Controlled Trial
Efficacy of a Web-Based Intervention to Increase Uptake of Maternal Vaccines: An RCT.
Tetanus, diphtheria, and acellular pertussis (Tdap) and influenza vaccines are recommended for pregnant women in each pregnancy, yet uptake is suboptimal. This study tested the efficacy of an online vaccine resource in increasing uptake of Tdap and influenza vaccines among pregnant women. ⋯ Web-based vaccination information sent to pregnant women can positively influence maternal influenza vaccine uptake. Because of potential scalability, the impact of robust vaccination information websites should be studied in other settings.
