Does Social Support Predict Depressive Symptoms? A Longitudinal Study of Midlife and Older Men Who Have Sex with Men from the Multicenter AIDS Cohort Study.

The present study was designed to identify social support classes across time among midlife (40-64 years) and older (65+ years) gay, bisexual, and other men who have sex with men (MSM), and whether social support protects against depressive symptoms in this population. This study applied longitudinal latent class analysis across five visits on 1,329 individuals age 40 or older at baseline using data from the Multicenter AIDS Cohort Study (MACS) Healthy Aging substudy collected from April 2016 to October 2018. We identified four classes of social support across time: Partner-centered, that is, high levels of support from one's primary partner(s) and moderate support from friends and family; Friend-centered, that is, high levels of support from friends and chosen family; Low, that is, low levels of support from all sources; and Robust, that is, high levels of support from all sources. We found differences in class membership by age, race/ethnicity, employment status, sexual identity, education, relationship status, and HIV status. Finally, compared to MSM in the low support class, men in the other classes had lower odds of depressive symptoms at the final visit. The most common type of social support was partner-centered, while the least common type was robust. These findings suggest that the presence of any social support, regardless of the source, protects against depressive symptoms.
