In Indonesia, rapid urbanization and shifting family structures may exacerbate this issue, yet data on its prevalence at the primary healthcare level remain limited. Objective: This study aimed to assess the prevalence of loneliness and identify key demographic correlates among community-dwelling elderly in the working area.

Significant demographic correlates included female gender (72.5%), age 60-69 years (78.9%), elementary education level (47.7%), unemployment status (69.7%), widowhood (51.4%), and low income (
