Sexual orientation disparities in food insecurity and food assistance use in U.S. adult women: National Health and Nutrition Examination Survey, 2005-2014.
BACKGROUND
Nearly 40 million American adults report past year food insecurity. This is concerning, as food insecurity is associated with chronic disease morbidity and premature mortality. Women disproportionately experience food insecurity, and sexual minority women (i.e., lesbian, bisexual, and heterosexual women reporting same-sex behavior; SMW) may be at greater risk for experiencing food insecurity disparities. The purpose of this study was to investigate patterns and prevalence of food insecurity and food assistance use in sexual minority and exclusively heterosexual women using population-level health surveillance data.


METHODS
Using pooled 2004-2014 National Health and Nutrition Examination Survey data (N = 7379), we estimated weighted point prevalence of past 12-month food insecurity, severe food insecurity, Supplemental Nutrition Assistance Program (SNAP) use, and emergency food assistance use. We then used Poisson regression with robust variance to estimate prevalence ratios comparing SMW to exclusively heterosexual women on all outcomes. Women were classified by sexual identity and lifetime same-sex behavior as lesbian (n = 88), bisexual (n = 251), heterosexual and reporting same-sex behavior (heterosexual WSW; n = 366), or exclusively heterosexual women (referent; n = 6674).


RESULTS
Between 20.6-27.3% of lesbian, bisexual, and heterosexual WSW reported past 12-month food insecurity (versus 13.1% of exclusively heterosexual women). All SMW reported greater prevalence of past 12-month food insecurity and severe food insecurity than exclusively heterosexual women: prevalence ratios (PR) ranged from 1.34 (95% confidence interval [CI], 1.05-1.70) to 1.84 (95% CI, 1.13-3.01). No differences were found in SNAP participation by sexual orientation, but more lesbians and heterosexual WSW reported using emergency food assistance in the past 12-months (PR = 1.89; 95% CI, 1.29-2.79 and PR = 1.43; 95% CI, 1.03-2.00 respectively).


CONCLUSIONS
All SMW reported higher prevalence of food insecurity than exclusively heterosexual women. Lesbians and heterosexual WSW were also more likely to rely on emergency food assistance. This is problematic as SNAP use may reduce food insecurity over time, but emergency food resources (e.g., food pantries) do not. More evidence is needed to understand the multilevel factors driving food insecurity in this population to develop policy and community-based efforts to increase SNAP participation and decrease food insecurity.
