Differential Effects of Social Support by Sexual Orientation: A Study of Depression Symptoms Among Older Canadians in the CLSA

Abstract

This study examined differences in symptoms of mental illness, specifically depression, by sexual orientation and examined the protective role of social support among lesbian, gay, and bisexual (LGB) older Canadians. Data were drawn from the Canadian Longitudinal Study on Aging, a national study of adults aged 45–85 years at baseline (n = 46,157). We examined whether the effect of sexual orientation on depression symptoms was moderated by four types of social support: emotional/informational support, affectionate support, tangible support, and positive social interaction. LGB identification was associated with increased depression symptoms relative to heterosexual participants. After adjustment for covariates, bisexual identity remained a significant predictor of depression symptoms. Low emotional/informational social support was associated with increased depression symptoms, an effect that was most pronounced for lesbian and gay participants. The findings contribute to the growing body of research on the mental health of older LGB people.
