The Dose-Response Relationship Between Physical Activity and Cardiometabolic Health in Young Adults.
Guidelines recommend 150 minutes of weekly moderate-to-vigorous physical activity (MVPA) for all adults, although physical activity level correlation with cardiometabolic health is not well characterized for young adults. We determined the dose-response relationship of MVPA on measures of cardiometabolic health in young adults. ⋯ The dose-response relationships between physical activity and cardiometabolic markers in young adults were predominantly linear, supporting public health calls for any increase in physical activity in this population.

Reducing the spread of infection during the COVID-19 pandemic prompted recommendations for individuals to socially distance. Little is known about the extent to which youth are socially distancing, what motivations underlie their social distancing, and how these motivations are connected with amount of social distancing, mental health, and social health. Using a large sample of adolescents from across the United States, this study examined adolescents' motivations for social distancing, their engagement in social distancing, and their mental and social health. ⋯ Understanding adolescents' motivations to engage in social distancing may inform strategies to increase social distancing engagement, reduce pathogen transmission, and identify individual differences in mental and social health during the COVID-19 pandemic.

Randomized Controlled Trial
Mechanisms of Action for Empirically Supported Interventions to Reduce Adolescent Sexual Risk Behavior: A Randomized Controlled Trial.
Adolescents are at high risk for sexually transmitted infections, including HIV. Interventions to reduce adolescent sexual risk often have modest outcomes. Understanding of the mechanisms of program effectiveness is needed to develop stronger interventions. We used a randomized controlled trial to examine mechanisms of response to two empirically supported interventions: motivational interviewing versus behavioral skills training. ⋯ The results indicate common mechanisms of action for these two interventions and support the use of transdiagnostic mechanisms of treatment impact for sexual risk reduction.
