The long-term mental health risk associated with non-heterosexual orientation

Abstract

Aims. Findings that describe the mental health risk associated with non-heterosexual orientation in young and middle-aged adults are from cross-sectional designs or fail to discriminate homosexual and bisexual orientations. This study examines the mental health risk of homosexual and bisexual orientation over an 8-year period.

Methods. Participants were from the age-cohort study, the Personality and Total Health Through Life Project, were observed twice every 4 years, and aged 20-24 (n = 2353) and 40-44 (n = 2499) at baseline.

Results. Homosexual orientation was unrelated to long-term depression risk. Risk for anxiety and depression associated with homosexual and bisexual orientations, respectively, were attenuated in fully-adjusted models. Bisexual orientation risk associated with anxiety was partially attenuated in fully-adjusted models.

Conclusions. Non-heterosexual orientation was not a major risk factor for long-term mental health outcomes. Instead, those with a non-heterosexual orientation were more likely to experience other mental health risk factors, which explain most of the risk observed amongst those with a non-heterosexual orientation.
