Individual capital and cognitive ageing in Guatemala

Using data from adults 50 years and older in Guatemala (N = 643), we assessed to what extent measures of individual capital-economic, social, intellectual, and biological-were associated with and account for variation in cognitive functioning, as measured by the Modified Mini-Mental Status Exam (M-MMSE). Measures of these components of individual capital are positively associated with cognitive functioning, and together with other attributes, account for 29.6 per cent of its variance. Schooling accounts for the largest unique share (5.3 per cent) of the variance, followed by household standard of living (2.0 per cent), church attendance (1.3 per cent), and z-score for height (0.9 per cent). In a setting like Guatemala-with low schooling, widespread poverty, malnutrition, and infectious disease-early life investments that increase schooling and improve nutrition may be valuable as investments to mitigate cognitive impairment in older adults and its contribution to the disease burden.
