Objectives:
To explore among older adults whether multivariate neighborhood profiles were associated with physical activity (PA) and BMI.
Methods:
Adults (66-97 years) were recruited from Baltimore-Washington, DC (n=360), and Seattle-King County, Washington (n=368), regions. Latent profile analyses were conducted using the Neighborhood Environment Walkability Scale. ANCOVA models tested for criterion validity of profiles by examining relationships to PA and BMI.
Results:
Neighborhood profiles differed significantly by as much as 10 minutes/day for moderate-to-vigorous PA, 1.1 hours/week for walking for errands, and almost 50 minutes/week for leisure PA.
Conclusions:
Environmental variables resulted in meaningful neighborhood patterns that explained large differences in seniors' health outcomes.
