Objective: To investigate the gender-specific longitudinal association between ethnic identification and obesity in young people.
Methods: Prospective study using population-based cohort data on self-reported ethnic identification (Multi-Ethnic Identification Measure), obesity and covariables. Multivariable logistic regression using interaction terms for sex and predictors estimated odds ratios and post-estimation calculated adjusted mean prevalence.
Results: Young men reporting stronger overall ethnic identification had about a 50% greater likelihood of being obese at wave 6 (OR 1.52, 95% CI 1.02-2.25]), compared to those with weaker identification. The monotonic association between ethnic identification and adjusted mean obesity prevalence was only seen in young men (Fig 1). Gender-specific findings further differed by ethnic group (Figs 2 & 3) and patterns also depended on the component of ethnic identification examined.
Conclusion: Although ethnic identification may offer protective health-related quality of life effects, there may be more insalubrious effects on other health outcomes such as obesity, and particularly for young men from certain ethnic groups. A greater understanding of the gender-specific role of ethnic identification in the development of obesity would benefit public health efforts to use culture as an obesity intervention among diverse young people
