Reference category = heterosexual by 2015. Data were weighted. Models included sexual identity, age, race/ethnicity, state, survey year, and identity-by-year interaction; odds ratios above 1.00 indicate a wider disparity between heterosexual youth and the specified sexual minority subgroup in 2015 compared with 2007, whereas odds ratios below 1.00 indicate a narrower disparity between heterosexual youth and sexual minority youth in 2015 compared with 2007. aOR in bold indicate p < 0.05.
