Loneliness has emerged as a significant public health concern among vulnerable populations, particularly gay, bisexual, and other men who have sex with men (MSM), and is shaped by sociodemographic and sociocultural factors. This observational, cross-sectional study aimed to estimate the prevalence of loneliness and examine its associations with sociodemographic and sociocultural factors among Brazilian MSM. A total of 1196 participants (mean age = 39.96 years, SD = 12.41) completed measures of loneliness (UCLA Loneliness Scale), sociodemographic characteristics, economic vulnerability, social and community capital, religiosity, and clinical–behavioral factors. More than half of the participants (52.7%) reported moderate or high levels of loneliness. A hierarchical multiple linear regression model was estimated and explained 23% of the variance in loneliness. Greater economic vulnerability and problematic substance use were linked to higher loneliness, whereas being in a romantic relationship, reporting a stronger sense of community belonging, and having social networks composed predominantly of LGBTQIA+ peers were linked to lower loneliness. The absence of formal religion was independently linked to higher loneliness, and HIV serostatus was not significantly related to loneliness after adjustment. These findings highlight the relevance of loneliness in this population and inform interventions targeting material vulnerability and community-based social support.
