Sexual Orientation and Gender Identity-Related State-Level Policies and Perceived Health Among Lesbian, Gay, Bisexual, and Transgender (LGBT) Older Adults in the United States

Associations Between Structural Stigma and Allostatic Load Among Sexual Minorities: Results From a Population-Based Study

OBJECTIVE

Structural forms of stigma and discrimination are associated with adverse health outcomes across numerous stigmatized groups, including lesbian, gay, and bisexual (LGB) individuals. However, the biological consequences of structural stigma among LGB populations are understudied. To begin to address this gap, we assessed associations between indicators of structural stigma (i.e., state-level policies) targeting LGB individuals and allostatic load (AL) indices representing physiological dysregulations.

METHODS

Pooled data from the continuous 2001-2014 National Health and Nutritional Examination Survey were analyzed (LGB: n = 864; heterosexual: n = 20,310). Ten state-level LGB-related policies (e.g., employment nondiscrimination protections, same-sex marriage) were used to operationalize structural stigma. A sex-specific AL index representing 11 immune, metabolic, and cardiovascular biomarkers was estimated. Multilevel models were used to examine associations between structural stigma and AL, net of nine individual-level characteristics (e.g., education, race/ethnicity, age, and health behaviors).

RESULTS

Sexual minority men living in states with low levels of structural stigma experienced significantly lower AL ( β = -0.45, p = .02) compared with sexual minority men living in states with high structural stigma (i.e., fewer protective policies). There was no significant association between structural stigma and AL among sexual minority women.

CONCLUSIONS

By demonstrating direct associations between structural stigma and indices of physiological dysregulation, our findings provide a mechanistic understanding of how the social environment can "get under the skin and skull" for sexual minority men in the United States. Future research should explore whether these mechanisms generalize to other marginalized groups exposed to structural stigma.

Structural stigma and LGBTQ+ health: a narrative review of quantitative studies

Health disparities related to sexual orientation and gender identity exist across multiple outcomes. Scholarship has begun to evaluate whether structural stigma-ie, societal-level conditions, cultural norms, and institutional policies that constrain opportunities, resources, and wellbeing-contributes to health burdens among LGBTQ+ individuals. We conducted a comprehensive review of quantitative studies examining this hypothesis. We found 98 articles that linked objective (ie, non-self-reported) measures of structural stigma to mental (n=57), behavioural (ie, substance use; n=27; HIV/AIDS or sexually transmitted infection; n=20), and physical (n=20) health outcomes. There was generally consistent evidence that structural stigma increases risk of poor health among LGBTQ+ individuals. Several methodological strengths were identified, including the use of multiple measures (eg, laws or policies [59%, 58 of 98]), designs (eg, quasi-experiments [21%, 21 of 98]), and samples (eg, probability-based [56%, 55 of 98]). However, important gaps exist. Just over half of studies included area-level covariates or non-LGBTQ+ comparison groups, which are necessary to address alternative explanations for the observed associations. Additionally, while studies (n=90) have begun to identify candidate mechanisms, only nine (10%) formally tested mediation. We offer suggestions for future research to advance this literature, which has implications not only for the identification of structural determinants of LGBTQ+ health but also for the development of public health interventions that reduce LGBTQ+ health disparities.
