Routine adolescent physical activity is a well-established predictor of positive health across the lifespan, although wide disparities in youth physical activity engagement persist across sex and race/ethnicity. Transportation barriers may be related to adolescents' ability to access physical activity opportunities. This study examines the association between neighborhood public transportation usage and adolescent physical activity using a national sample. ⋯ This study found an association between neighborhood public transportation usage and adolescent moderate-to-vigorous physical activity, particularly among non-Hispanic Black and Hispanic adolescent girls. Findings from this research have the potential to inform targeted interventions for promoting adolescent physical activity to ultimately reduce chronic health disparities across the lifespan.

Among U.S. adolescents, the knowledge that air pollution can impact health is relatively high and varies by the demographics of the respondents and the places they live, but the influence of asthma status is unknown. This study assesses the role of asthma in U.S. adolescents' awareness, perceptions, and behaviors related to air pollution. ⋯ Despite the well-known risk of asthma exacerbations from air pollution exposure, air quality awareness was similar among adolescents with and without asthma. These findings reveal the areas in which air quality awareness and behaviors to reduce exposure can be improved among adolescents with and without asthma.

Long-Acting Reversible Contraception, Condom Use, and Sexually Transmitted Infections: A Systematic Review and Meta-analysis.
Given mixed findings regarding the relationship between long-acting reversible contraception and condom use, this systematic review and meta-analysis synthesizes studies comparing sexually transmitted infection‒related outcomes between users of long-acting reversible contraception (intrauterine devices, implants) and users of moderately effective contraceptive methods (oral contraceptives, injectables, patches, rings). ⋯ Promoting condom use specifically for sexually transmitted infection prevention may be particularly important among long-acting reversible contraception users at risk for sexually transmitted infections, including adolescents and young adults.

Since 2012, HIV pre-exposure prophylaxis (PrEP) has been available to prevent HIV transmission; yet, uptake, adherence, and persistence to PrEP have been suboptimal. This narrative review examines the latest interventions and programs to improve all 3 stages of PrEP adherence and reviews ongoing studies to promote effective PrEP use. From 2017 to 2020, a total of 20 studies analyzed different individual- and structural-level approaches to increase PrEP adherence, including behavior change interventions, technology-based interventions (e.g., short message service messages and mobile applications), and alternate delivery strategies (e.g., pharmacy-based PrEP, integration with other services, and home delivery). ⋯ Proven and promising approaches may work well in combination and may also need to be adapted with the introduction of long-acting pre-exposure prophylaxis formulations. Collectively, this body of work indicates considerable progress toward understanding the role PrEP adherence will play in Ending the HIV Epidemic in the U. S. that will be bolstered by the outcomes of ongoing trials.
