Impact of Changes in Shared Public Activity Spaces on Hypertension Risk: Evidence from Longitudinal, Nationally Representative Study - Shared public activity spaces, such as walking trails, parks, and sidewalks, promote active living among aging adults by offering safe, accessible opportunities for movement without financial cost. Over recent decades, these spaces have undergone substantial change, ranging from modest, small-scale upgrades to changes embedded in large-scale community redevelopment. However, prior studies provide limited evidence on which types of change matter most for health, for whom, and through what mechanisms. Most studies have treated public activity spaces as static features rather than measuring temporal changes. When changes were examined, few quantified the magnitude or type of change, accounted for residential mobility, or investigated potential mediating pathways. In studies of largescale redevelopment, changes to public activity spaces have been combined with commercial and residential development, making it difficult to identify their independent health effects. Using longitudinal data from the nationally representative Health and Retirement Study, this study investigates how changes in shared public activity spaces affect long-term trajectories of hypertension risk, accounting for residential mobility. We first identify the physical activity-related pathways linking small-scale changes in public activity spaces within residential neighborhoods to long-term hypertension risk. Additionally, we determine how changes to public activity spaces embedded in largescale redevelopment projects are related to these trajectories. Findings will clarify which types of changes in shared public activity spaces are most strongly associated with cardiovascular health in later life and the physical activity pathways that mediate these associations. This evidence can inform community organizations that offer physical activity programming for older adults, and can help providers in clinical settings tailor counseling about physical activity to the everyday environments their older patients actually encounter. The measures and analytic approach developed here will establish a foundation for future research on how everyday environments shape cardiovascular aging.
