However, their underlying mechanisms remain unclear. This study investigated mediating effects of cognitive and structural social capital (SC) in relationships between neighborhood environments and mental well-being among older adults.<h4>Research design and methods</h4>We conducted a cross-sectional analysis of 1,277 community-dwellers aged 60 years and older in Hong Kong in 2021. The Warwick-Edinburgh Mental Well-being Scale assessed mental well-being. Perceived age-friendly environment was assessed. Objective neighborhood environment was measured by the number of neighborhood facilities (e.g., transportation, community centers, leisure facilities) within 200-m and 500-m buffer areas from respondents' residences. Structural equational modeling was used.<h4>Results</h4>Perceived age-friendly environment regarding community and health support had a protective role on mental well-being. More community centers were directly associated with better affective-emotional well-being, while more passive leisure facilities directly lowered psychological-functioning well-being. Cognitive SC outweighed structural SC in mediating relationships of neighborhood environment on mental well-being.<h4>Discussion and implications</h4>Our findings advance the ecological model of aging by providing evidence for cognitive and structural SC as mediators to explain the relationship between neighborhood environment and mental well-being. Policy implications for optimizing mental well-being in aging societies are discussed.Innovation in agingigac070https://www.ebi.ac.uk/biostudies/studies/S-EPMC9799048biostudies-literatureNeighborhood Environment and Mental Well-Being Among Chinese Older Adults: The Mediating Role of Social Capital.PMC9799048Chan SWLiu YLum TYSGuo YChan OFLu SChui CfalseNeighborhood Environment and Mental Well-Being Among Chinese Older Adults: The Mediating Role of Social Capital.<h4>Background and objectives</h4>Neighborhood environments are increasingly recognized as associated with mental well-being among older adults.
