Associations Between Physical Activity and Nutrition Self-efficacy and Self-reported Physical Activity in Residents of Resource-limited Neighborhoods

<h2>Abstract</h2><h3>Objective</h3> We explored the relationship between lifestyle behavior, self-efficacy, and self-reported physical activity (PA) among individuals with overweight/obesity residing in resource-limited neighborhoods. <h3>Methods</h3> Using data from the Washington DC Cardiovascular Health and Needs Assessment and the Step It Up digital health intervention study, we examined relationships between self-efficacy and self-reported PA participation. Individuals completed the physical activity and nutrition self-efficacy (PANSE) scale and the Global Physical Activity Questionnaire, which assesses self-reported PA participation. Logistic and gamma regression models were performed to assess associations between PANSE quintiles and: (1) odds of any PA participation and (2) duration of PA participation. <h3>Results</h3> The sample (N=227) had mean age 57.71 (±12.60), body mass index 34.55 (±7.19) and were predominantly female (90.75%). The majority had college education (57.55%) and less than $60,000 annual income (44.15%). Individuals who scored in the third quintile, compared to the first quintile, were 3.26 (95% CI: 1.18, 9.02) and 3.97 (95% CI: 1.46, 10.82) times more likely to report MPA and MSA participation respectively, after adjusting for sociodemographic factors. Those who scored in the third and fifth quintiles were 3.91(95% CI: 1.28, 11.97) and 5.92 (95% CI: 1.90,18.47) times more likely to meet the guideline recommended 150 minutes weekly moderate-to-vigorous PA. <h3>Conclusion</h3> Higher PA self-efficacy is associated with higher odds of participation, PA duration, and the odds of meeting the guideline recommended weekly MVPA. Interventions that augment self-efficacy may be particularly important in improving cardiovascular health by enhancing PA in individuals with obesity.
