Factors Associated with Sexual Orientation and Gender Disparities in Chronic Pain Among U.S. Adolescents and Young Adults.

Abstract

This research investigated factors associated with sexual orientation disparities in chronic pain frequency among youth. Data were analyzed from 4534 female and 3785 male youth from Waves I–IV (1995–2009) of the U.S. National Longitudinal Study of Adolescent to Adult Health. Gender-stratified weighted logistic regression models controlled for sociodemographic characteristics and included sexual orientation (primary predictor) and frequency of three types of chronic pain (outcomes). Models with sexual orientation only were compared to models with factors hypothesized to increase or decrease risk of pain. Significant odds ratios (OR) for chronic pain frequency (daily/weekly vs. rarely) with confidence intervals (CI) and associated factors are reported. Compared to same-gender heterosexual females, mostly heterosexuals were more likely to report headaches (OR = 1.40, CI = 1.09, 1.79) and mostly heterosexuals and bisexuals were more likely to report muscle/joint pain (mostly heterosexual OR = 1.69, CI = 1.29, 2.20; bisexual OR = 1.87, CI = 1.03, 3.38). Compared to same-gender heterosexual males, gay males were more likely to report headaches (OR = 2.00, CI = 1.06, 3.82), but less likely to report muscle/joint pain (OR = 0.28, CI = 0.11, 0.74). Significant disparities were attenuated by up to 16% when associated factors were added to the model. Sexual orientation disparities in chronic pain were partially explained by associated factors, but more research is needed to develop intervention and prevention strategies.
