Race-specific associations between psychological distress and obesity: the role of social cohesion

Nearly two-thirds of Black women in the US are obese. Studies have focused more on lifestyle and behavioral factors to explain racial disparities; less research has examined psychosocial factors such as psychological distress and social cohesion. While research suggests that social cohesion may confer benefits for health, no studies have assessed how social cohesion is related to both mental health and obesity, and potential racial differences. Our study examined associations between psychological distress, social cohesion, and obesity among Black and White adult women.Data are from the 2014-2018 National Health Interview Survey (Psychological distress was associated with a 1.19 and 1.31 higher odds of obesity for Black (95% confidence interval: 1.05, 1.36) and White women (1.24, 1.39), respectively. Social cohesion was associated with a 0.75 lower odds of obesity among White (0.69, 0.81) but not Black women (odds ratio 0.94; 0.80, 1.10). Tests of interaction indicated no differences by social cohesion or race in the association between psychological distress and obesity.Findings highlight complex relationships between psychological distress, obesity, and social cohesion in Black and White women. Public health efforts should focus on understanding mechanisms relating social factors to health.
