College Community-Based Physical Activity Support at a Public University During the COVID-19 Pandemic: Retrospective Longitudinal Analysis of Intra- Versus Interpersonal Components for Uptake and Outcome Association.

Background: College students are vulnerable to setting long-term trajectories of low physical activity (PA) but are reachable via mobile health fitness tracking (eg, mobile health step counting) and interpersonal support tailored to the college community. However, no studies have statistically isolated the appeal and influence of these intra- and interpersonal components in college-based PA interventions.

Objective: This study retrospectively examined a college-based PA promotion program at a northeast US public university during the COVID-19 pandemic to (1) test the impact of student status on the use of intervention components and (2) determine whether such use was associated with successful retention and goal achievement in the program.

Facilitating the Virtual Exercise Games for Youth with Type 1 Diabetes (ExerT1D) Peer Intervention: Protocol Development and Feasibility.

Aims: Adolescents with type 1 diabetes (T1D) face several unique challenges to engaging in moderate-to-vigorous physical activity (MVPA), including uncertainty with diabetes self-management, risk of hypoglycemia, limited access to safe or supportive environments, and diabetes-specific stigma. Opportunities for T1D peer activities with T1D role model support are limited. To address this need, we tested iterative refinements of pilot Virtual Exercise Games for Youth with T1D (ExerT1D) for feasibility and acceptability.
