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.

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.

Existing socioeconomic and racial disparities in healthcare access in New York City have likely impacted the public health response to COVID-19. An ecological study was performed to determine the spatial distribution of COVID-19 testing by ZIP code Tabulation Area and investigate if testing was associated with race or SES. ⋯ In New York City, COVID-19 testing has not been proportional to need; existing socioeconomic and racial disparities in healthcare access have likely impacted public health response. There is urgent need for widespread testing and public health outreach for the most vulnerable communities in New York City.

Associations between time spent on physical activity, sedentary behavior, and sleep and quality of life are usually studied without considering that their combined time is fixed. This study investigates the reallocation of time spent on physical activity, sedentary behavior, and sleep during the 24-hour day and their associations with quality of life. ⋯ Moderate-to-vigorous physical activity is important with regard to the quality of life of middle-aged and elderly individuals. The benefits of preventing less time spent in moderate-to-vigorous physical activity were greater than the benefits of more time spent in moderate-to-vigorous physical activity. These results could shift the attention to interventions focused on preventing reductions in moderate-to-vigorous physical activity levels. Further longitudinal studies are needed to confirm these findings and explore causality.

Rates of adolescent substance use have decreased in recent years. Knowing whether nonmedical marijuana legalization for adults is linked to increases or slows desirable decreases in marijuana and other drug use or pro-marijuana attitudes among teens is of critical interest to inform policy and promote public health. This study tests whether nonmedical marijuana legalization predicts a higher likelihood of teen marijuana, alcohol, or cigarette use or lower perceived harm from marijuana use in a longitudinal sample of youth aged 10-20 years. ⋯ It is important to consider recent broad declines in youth substance use when evaluating the impact of nonmedical marijuana legalization. States that legalize nonmedical marijuana for adults should increase resources for the prevention of underage marijuana and alcohol use.
