    Community-Based Exercise Program Attendance and Exercise Self-Efficacy in African American Women

    Rates of chronic disease and physical inactivity are disproportionately high among African American women. Despite the known benefits of physical activity and an increasing number of programs designed to increase activity, attendance rates to many exercise programs remain low. There is much to learn about program types, such as healthy lifestyle programs (HLP); individual factors, such as self-efficacy; and mediating variables that may influence exercise program attendance. An observational study design was used to compare exercise self-efficacy and attendance in a community-based exercise program in African American women who were enrolled in a HLP (N = 53) to women who were not (N = 27). Exercise program attendance was gathered across six months; demographics, self-efficacy and physical activity behaviors were assessed through surveys; and physiological variables (resting heart rate and blood pressure, height, and weight) and physical fitness (muscular strength and endurance and cardiovascular endurance) were measured at baseline. Descriptive statistics were used to describe participants and groups were compared using T-tests, chi-square and non-parametric statistics. Finally, mediation analyses were conducted using multiple regression models to assess self-efficacy as a potential mediator to exercise program attendance. Women who enrolled in this study were of low income (61% having an annual income less than $20,000), obese with a mean (standard deviation) body mass index (BMI) of 37.7 (7.6), pre-hypertensive with a mean (standard deviation) systolic blood pressure of 125.9 (14.4), and scored poorly and marginally on two fitness tests. On average, women reported being Moderately Confident in their ability to exercise regularly, yet had low attendance in the exercise program with a median number .5 days over six months and there were no significant differences in exercise self-efficacy (p = .23) or attendance in the exercise program between groups (p = .79). Additionally, exercise self-efficacy was not a mediating variable to program attendance. Women in this study had little discretionary income and several chronic disease risk factors, yet exercise program attendance was low even in those enrolled in a HLP. Identifying factors that increase exercise self-efficacy and factors that influence attendance beyond self-efficacy may help future program design and attendance.
