The impact of demographic and self-management factors on physical activity in women.

Aim: Guided by the Individual and Family Self-Management Theory, this study examines demographic and self-management variables that impact the outcome of physical activity.

Background: Multiple sources indicate relationships between physical activity and reduced incidence of cardiovascular disease. Women engage in significantly less physical activity than guidelines recommend.

Methods: Data collected in women included demographic/situational factors and external influencing level factors including knowledge and beliefs, social facilitation, and outcome expectancy. The outcome behavior physical activity was also assessed. Correlation and hierarchical multiple regression were used to examine the relationship of demographic/situational and external influencing factors to physical activity.

Results: The sample included 119 women (mean age 40.96, 89.1% Caucasian, 51.3% Married, 95% high school graduates). Education was positively correlated with exercise benefits (r = 0.235,p = .010). Gross family income (r = 0.191,p = .043), work status (r = 0.238,p = .009), and health insurance(r = 0.228,p = .013) were positively correlated to family participation, and work status was positively correlated to friend participation (r = 0.263.p = .004). In the final model, demographic/situational factors (step 1) explained 12.9% of the variance in physical activity (p < .05). Knowledge and beliefs, social support, and outcome expectancy (step added an additional 0.9% of variance physical activity levels).

Conclusions: Findings suggest that demographic/situational factors contribute more to explaining variability in physical activity levels than external influencing factors. This suggests that in addition to considering demographic variables, further research to explore other demographic/situational and external influencing factors that affect physical activity specifically in women is necessary.
