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.
