## Abstract

PA-19-195 Ruth L. Kirschstein National Research Service Award Individual Predoctoral Fellowship, NOT-MD-
19-001, Notice of Special Interest in Research on the Health of Sexual and Gender Minority Populations: A
glaring sexual orientation-related disparity is in the prevalence of disordered eating behaviors (DEBs),
including severe calorie restriction, self-induced vomiting, laxative and diet pill use, and binge-eating. One in
three sexual minority young people (lesbian, gay, bisexual, and other non-heterosexual individuals) engage in
DEBs, a seven-fold higher odds than their heterosexual peers. There are considerable health consequences
associated with these behaviors, such as metabolic and reproductive health issues, substance use,
depression, and suicidality. However, research on DEBs lags behind that on other sexual orientation-related
health disparities, with critical gaps including failing to consider both within-group diversity in risk and the
upstream social determinants of the observed disparities. Importantly, experiencing multiple forms of social
disadvantage has been shown to increase risk of eating-related pathologies, including DEBs. Gender
nonconforming and higher-weight (i.e., overweight/obese) statuses are especially relevant dimensions of
disadvantage to consider, as these groups experience high levels of appearance-based discrimination and
may use DEBs as dangerous body-modification practices to cope. Sexual minorities who experience further
marginalization through membership in these groups may encounter unique and/or compounding social
stressors that exacerbate risk. Examining the intersectionality of sexual orientation, gender expression, and
weight status is thus critical to addressing these research gaps. Using the Growing Up Today Study (GUTS), a
national longitudinal cohort study of over 27,000 participants (~20% of whom are sexual minorities), the aims of
this proposal are to: 1) Quantify the intersectional effects of sexual orientation, gender expression, and weight
status on risk of DEBs among young adults; 2) Quantify the effects of interpersonal-level determinants (bullying
victimization, weight-based harassment) on risk of DEBs by sexual orientation, and evaluate differences by
gender expression and/or weight-status; and 3) Quantify the effects of structural-level determinants
(discriminatory social conditions, state policies) on risk of DEBs by sexual orientation, and evaluate differences
by gender expression and/or weight-status. The National Academy of Medicine’s 2011 landmark report on
sexual minority health stressed the importance of adopting an intersectional framework for disparities research
to inform the development of inclusive health equity efforts. Applying this lens through leveraging novel
statistical methods will further understanding of a critically understudied sexual minority health issue and help
identify high-risk subgroups and modifiable contextual risk factors. A tailored training plan accompan...
