Neighborhood-based social capital and cognitive function among older adults in five low- and middle-income countries: Evidence from the World Health Organization Study on global AGEing and adult health.

Different indicators of neighborhood-based social capital, which are well-established protective resources for cognitive function, may have varied relationships with cognitive function cross-nationally. This finding provides a better understanding of the mechanisms by which neighborhood social capital may contribute to better cognitive function in LMICs than high-income countries, potentially due to differences in neighborhood environments, health systems, and availability of public resources.
