Sexual orientation disparities in preventable disease: A fundamental cause perspective

Abstract

Objectives. To determine whether fundamental cause theory (which posits that, in societal conditions of unequal power and resources, members of higher-status groups experience better health than members of lower-status groups because of their disproportionate access to health-protective factors) might be relevant in explaining health disparities related to sexual orientation.Methods. We used 2001 to 2011 morbidity data from the Stockholm Public Health Cohort, a representative general population–based study in Sweden. A total of 66 604 (92.0%) individuals identified as heterosexual, 848 (1.2%) as homosexual, and 806 (1.1%) as bisexual. To test fundamental cause theory, we classified diseases in terms of preventability potential (low vs high).Results. There were no sexual orientation differences in morbidity from low-preventable diseases. By contrast, gay or bisexual men (adjusted odds ratio [OR] = 1.48; 95% confidence interval [CI] = 1.13, 1.93) and lesbian or bisexual women (adjusted OR = 1.64; 95% CI = 1...
