Randomized Controlled Trial
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.

Sugar-sweetened beverages are a key driver of obesity. Portion-size regulations typically limit the volume of unsealed sugar-sweetened beverage containers to 16 fluid ounces. These regulations could reduce sugar-sweetened beverage consumption, but whom these policies would affect remains unknown. This study evaluates demographic groups likely affected by hypothetical national portion-size regulations modeled on policy language and scopes from New York City and California. ⋯ Portion-size regulations would likely have a greater effect on younger, male, and less-educated adults. Policy effects would likely be larger if these regulations are written to encompass more food sources.

Local governments are often innovators of public health policy-making, yet states are increasingly preempting or prohibiting local control over public health issues. Previous research identified examples of strategies used by state legislatures to pass preemption in ways that may obscure public discussion about preemption or the topics preempted or enhance the strength of a previously passed preemptive law. ⋯ Strategies employed to pass preemption obscure public debate about preemption and the underlying public health and social justice issues at stake while minimizing the ability of local governments to protect their populations and the nation to learn from local policy successes.

The relationship between e-cigarette use and cigarette smoking is the subject of ongoing debate. There is limited research on e-cigarette use and changes in the frequency of cigarette smoking. This study examines whether the frequency of e-cigarette use is associated with changes in cigarette smoking behavior among U.S. adults. ⋯ Although e-cigarette use may reduce cigarette smoking frequency among continuing smokers, findings suggest that e-cigarette use may be associated with cigarette smoking relapse among former smokers.

Sexual orientation‒related disparities in alcohol use disorder are well-established. Yet, the degree to which sexual orientation differences in alcohol use disorder vary across the life course is poorly understood. There is also a limited understanding of how exposure to minority stressors and their relationship with alcohol use disorder vary as a function of age. ⋯ Sexual orientation-related disparities in alcohol use disorder are dynamic across the life course and point to critical times for screening and intervention. Developmental perspectives of sexual minority health inequities demand focused research attention as findings will help to identify strategies for promoting sexual minority health at distinct points in the life course.
