Background: Few youth engage in sufficient daily moderate-to-vigorous physical activity (MVPA), and the likelihood of meeting guidelines declines through secondary school. Physical education (PE) can afford youth with opportunities for MVPA. Therefore, the purpose of this study was to investigate the impact of changes in PE enrollment on MVPA and…

Background: Early sexual reproductive health (SRH) education is linked to a reduction in risky sexual behaviors. Sexually transmitted infections (STIs) are rising at alarming rates. Risky sexual behaviors, including initiation of sex before age 13, having more than four sexual partners, and lack of use of condoms, increase the chance of infection…

Background: Internationally 18% of youth are obese. Fitness testing can be used to establish fitness surveillance, which can inform policy and targeted interventions aimed at addressing obesity. The purpose of this study was to estimate the prevalence of overweight, obesity, and low fitness in Idaho school-aged youth through a pilot study.…

Background: The experiences of youth with intersecting LGBTQ+ and Asian American (AA) identities have been largely unexplored.
