Association of Cognitive Impairment With Migrant Status Among Older Adults in India: A Cross-Sectional Study


 Introduction Among various health implications for older adult, cognitive impairment and related dementias are significant public health concern in many low and middle income countries, including India and lack due attention in policy arena. Socio-economic and health vulnerability are associated with cognitive impairment among older adults. Therefore the present study explores the prevalence and determinants of cognitive impairment among older adults in India with special reference to migrant status of older adults. MethodsData for this study was utilized from recent release of Longitudinal Ageing Study in India (LASI) wave 1 2017-19. The LASI is a nationally representative survey over 72000 older adults age 45 and above across all states and union territories of India. The present study is conducted on the eligible respondent’s age 60 years and above. The total sample size for the present study is 31,464 older adults aged 60 years and above (Male-15,068; Female-16,366). Descriptive and logistic regression analysis carried to fulfil the objective of the study. ResultsOverall, the prevalence of cognitive impairment among male older adults was 6.4% and female older adults 19.8%. Non-migrant status (6.8%) was more likely to face cognitive impairment than migrant status (5.7%) among older adults. The high prevalence of cognitive impairment were found with increasing socio-economic, demographic and multi-morbidities among older adults. Older adults (male 6.7% vs. female 20.2%) with no social participation were more likely to be face cognitive impairment. The result of logistic regression of our study is supported the bivariate analysis. Older adults with migrant status were more likely to be suffered from the cognitive impairment with unadjusted [UOR; 1.57, CI: 1.45-1.70] & after adjusting with covariates [AOR; 1.14, CI: 1.03-1.26] as compared to non-migrant status. Among the individual factors, odds of impairment was very high for the oldest-older adults age group [AOR: 2.95, CI: 2.59-3.36] as compared to young-older adults and further, female older adults were more likelihood to be cognitive impairment [AOR: 1.99, CI: 1.77-2.24] than their counterparts. Similar findings were also found with socio-economic and health vulnerability among older adults.Conclusion The study demonstrates that female older adults need more care and support from community and government as they face higher cognitive impairment. Further, the results significantly varied across different socio-economically, demographically, regionally in cognitive impairment and those who were suffering with co-morbidities. Comprehensive primary health care with community health approach may improve the health status of older adults in later period of life.
