Examining the Associations between Walk Score, Perceived Built Environment, and Physical Activity Behaviors among Women Participating in a Community-Randomized Lifestyle Change Intervention Trial: Strong Hearts, Healthy Communities.

ABSTRACT: Little is known about the relationship between perceived and objective measures of the built environment and physical activity behavior among rural populations. Within the context of a lifestyle-change intervention trial for rural women, Strong Hearts, Healthy Communities (SHHC), we examined: (1) if Walk Score (WS), an objective built environment measure, was associated with perceived built environment (PBE); (2) if WS and PBE were associated with moderate-to-vigorous physical activity (MVPA); and (3) if MVPA changes were modified by WS and/or PBE. Accelerometers and questionnaires were used to collect MVPA and PBE. Bivariate analyses and linear mixed models were used for statistical analyses. We found that WS was positively associated with perceived proximity to destinations (p < 0.001) and street shoulder availability (p = 0.001). MVPA was generally not associated with WS or PBE. Compared to controls, intervention group participants increased MVPA if they lived in communities with the lowest WS (WS = 0), fewer perceived walkable destinations, or extremely safe perceived traffic (all p < 0.05). Findings suggest that WS appears to be a relevant indicator of walkable amenities in rural towns; results also suggest that the SHHC intervention likely helped rural women with the greatest dearth of built environment assets to improve MVPA.

Project description:IntroductionRural women have higher rates of cardiovascular disease than their nonrural counterparts, partially because of their social and environmental contexts. The study objective is to test a refined version of the multilevel Strong Hearts, Healthy Communities intervention, which used extensive process and outcome evaluation data from the original randomized trial to optimize effectiveness as measured by improved Simple 7 score, a composite measure of cardiovascular disease risk.Study designThe intervention was implemented in a 6-month, delayed intervention, community-randomized trial; control participants received the program following 24-week outcome assessment. The study was conducted in 2017-2018; data analysis occurred in 2018-2019.Setting/participantsThe study was conducted in 11 rural, medically underserved towns in New York. Participants were women aged ≥40 years who were either (1) obese or (2) overweight and sedentary.InterventionThe intervention group received 24 weeks of hour-long, twice-weekly classes including strength training, aerobic exercise, and skill-based nutrition- and health-related education, as well as civic engagement activities focused on healthy food and physical activity environments.Main outcome measuresMeasures included weight and height; blood pressure; blood cholesterol; blood glucose; and self-reported smoking, diet, and physical activity behaviors. Individual Simple 7 components were examined, and mixed linear regression analyses were used to examine change in Simple 7 score.ResultsA total of 182 participants were randomized. Compared with control participants, the intervention group had greater improvements in Simple 7 score (difference=1.03, 95% CI=0.44, 1.61, p<0.001) and 3 of the Simple 7 components (physical activity, healthy diet score, and BMI).ConclusionsThese findings highlight the importance of rigorously evaluating programs in real-world community settings and, when appropriate, revising and retesting interventions to optimize dissemination potential.Trial registrationThis study is registered at www.clinicaltrials.gov NCT03059472.
