Abstract P361: Body Image Dissatisfaction Influences Cardiovascular Health in Overweight and Obese African American Women

Abstract

Introduction: African American women are 5 times less likely than white women to meet at least 5 or more ideal cardiovascular health metrics as defined by the American Heart Association Life’s Simple 7 (LS7) components (smoking, diet, physical activity, BMI, blood pressure, total cholesterol, and glucose). There are few studies probing the influence of sociocultural factors, such as body image dissatisfaction (BID), on these disparities. A better understanding of the impact of BID on cardiovascular health could assist in the design of more effective behavior change interventions for African American women. Hypothesis: We hypothesized that BID would have a negative association with cardiovascular health in overweight and obese African American women. Methods: We enrolled 32 women (mean age 49 years [SD 12.9]), from 5 predominantly African American churches participating in a larger community-based participatory study (FAITH! App Pilot Study) of a mobile health lifestyle intervention among African American women and men. We conducted a cross-sectional analysis of baseline data to evaluate the association between BID and both cardiovascular health and select psychosocial factors (e.g. motivation for healthy eating, diet self-regulation). A LS7 composite score was calculated as a measure of overall cardiovascular health (range 0-14). The Pulvers scale, consisting of images of women across the BMI spectrum, was used to measure perceived current and goal body size (rating of figures, 1-9; underweight to very obese). A BID score was calculated as the difference between perceived current and desired body image (range -8-8; BID < 0 [desire to be heavier], BID > 0 [desire to be thinner], BID = 0 [no dissatisfaction]). The BID score range for our cohort was 0-4. Thus, we categorized BID as no/low BID (BID score 0-1) or high BID (BID score 2-4). Results: Twenty-two percent (7/32) of women were overweight (BMI 25-29.9) and 78% (25/32) were obese (BMI (≥ 30). Forty-four percent (14/32) had no/low BID and 56% (18/32) had high BID. Those with high BID were more likely to be obese as compared to no/low BID (94% (17/18) versus 57% (8/14), p=0.03). Although not statistically significant, the mean LS7 composite score was 1 point higher among those with no/low BID, versus high BID (8.83 versus 7.76, p=0.25). Compared to women with high BID, those with no/low BID were more likely to have greater: intrinsic motivation (P=0.01) and integrated regulation for healthy eating (P=0.007), and self-regulation to reduce fat and caloric intake (P=0.01). Conclusion: Ultimately, although small, our study suggests that African-American women with obesity are more likely to have high BID. High BID was associated with lower motivation and self-regulation, which predict cardiovascular health. BID and other psychosocial factors for behavior change are potential targets for culturally-tailored lifestyle interventions in this group.
