Compared to straight adults, lesbian females had significantly higher odds of being overweight (OR (odds ratio) 1.33 95% CI (confidence interval) 1.17–1.53), whereas gay males had significantly lower odds (OR 0.66 95% CI 0.59–0.73). In addition, subgroup analyses were performed for both males and females. The propensity score matching technique was used to address covariate imbalance among sexual identity groups. We grouped participants according to sexual identity (straight, lesbian or gay, bisexual, and other/don’t know/not sure). Data were drawn from 2014–2017 Behavioral Risk Factor Surveillance System (BRFSS) surveys ( n = 716,609). In the present study, we examined whether overweightness and obesity vary by sexual minority subgroup using a large, nationally representative sample. There is evidence that sexual minority populations have a potentially heightened risk of poor health outcomes due in part to the discrimination they may face.
