Sexual orientation–based disparities in food security among adults in the United States: results from the 2003–2016 NHANES

Abstract

Access to sufficient, safe, culturally appropriate, and nutritious food is essential for maintaining both physical and mental health. Despite a growing body of evidence suggesting that sexual minority (SM) people experience significant disparities in socioeconomic and material resource security, there remains a paucity of empirical studies examining the prevalence of food insecurity among SM people relative to their heterosexual peers. To determine the prevalence of adult and household food insecurity across sexual orientation groups in the United States after adjusting for multiple covariates. We combined 7 cycles of US NHANES, 2003-2016 (N=21,300) to examine sexual orientation-based disparities in adult food security among lesbian/gay (n=373), bisexual (n=606), same-sex experienced (SSE, n=693), other sexual minorities (OSMs, n=88), and heterosexual (n=19,540) people. Food (in)security was measured using the US Food Security Survey Module and categorized as secure, marginally insecure, moderately insecure, and severely insecure. Severe adult food insecurity was higher among bisexuals (17.16%; 95% CI: 14.36, 20.38), SSE (13.71%; 95% CI: 11.34, 16.48), OSMs (12.50%; 95% CI: 7.04, 21.24), and lesbians/gays (13.14%; 95% CI: 10.07, 16.97) compared with heterosexuals (8.23%; 95% CI: 7.85, 8.62). Multivariable multinomial logistic regression analysis adjusting for gender, race/ethnicity, age, citizenship, education, household size, income, cycle year, emergency food use, and Supplemental Nutrition Assistance Program participation showed that bisexuals, OSMs, SSE, and lesbians/gays were more likely to experience moderate to severe food insecurity compared with heterosexuals. SM people are significantly more likely to experience increased likelihood of food insecurity relative to their heterosexual peers.
