The Association of Cultural Identification with Obesity among African Americans.

Introduction: The influence of culture on body mass index (BMI) and obesity within the African American population is an underexplored area in the literature. Therefore, this study explored the extent to which cultural identity was associated with BMI and obesity among African Americans and whether the association of cultural identity with obesity differed between males and females.

Methods: Participants were African Americans (n = 304) who responded to an online survey. BMI was calculated using self-reported weight and height; a BMI ≥ 30 indicated obesity. Sex assigned at birth was measured by self-report, and identification with African American culture was assessed using scores from six Black Identity Classification Scale (BICS) subscales. Primary analyses were conducted using a series of linear and logistic regression analyses.

Results: In almost all cases, BICS was not associated with BMI and obesity among all African Americans, but moderation analyses revealed that stronger identification with certain subscales of BICS, such as Afrocentrism, Black Americanism, and Racial Salience, was associated with an increase in the odds of obesity for males and not for females.

Conclusions: Study findings suggest that culture may influence obesity differently among males and females. Uncovering mechanisms linking cultural identification to obesity will provide novel contributions to behavioral interventions designed to reduce obesity within the African American population.
