Determinants of acquired disability and recovery from disability in Indian older adults: longitudinal influence of socio-economic and health-related factors

Abstract Background There is a higher burden of functional disability for Indian older adults with substantial variations across different geographic regions and socioeconomic groups as compared to other ageing Asian countries. Thus, using a national sample of older adults aged 60+ years, we aim to explore how common is acquiring of disability and recovery from disability among the older population of a developing country like India, and how do the various socioeconomic and health-related conditions impact this transition in disability status. Method The current study uses two waves of the India Human Development Survey (IHDS) and is based on panel data of 10,527 older adults. Both bivariate and multiple variable regression analysis were performed using two binary outcome variables in this study – whether older adults acquired disability and recovered from disability between round-I and round-II, respectively. Results Nearly 31.5% and 4.4 % of older adults have acquired and recovered disability across the two rounds respectively. About 38.5% and 45.8 % of female older adults’ disability status changes to disable and recovered in round-II respectively. A lesser proportion of older adults have recovered from a disability who have a chronic disease in round-I. Cataract chronic conditions among older adults in round-I had shown 1.45 times (CI: 1.07–1.97) a significantly higher likelihood of acquiring disability in round-I. Older adults who were unmarried and were not working in round-I have 1.12 times (CI: 1.01–1.25) and 1.21 times (CI: 1.06–1.39) higher likelihood of acquiring disability in round-II respectively. Recovering from disability was mostly seen among older adults who belong to the richest (OR: 2.38, CI: 1.31–4.33) and medium (OR: 2.16, CI: 1.27–3.69) wealth quintile households. Older adults residing in the central region of India have 2.72 times (CI: 2.31–3.19) significantly higher chance of acquiring disability than those who were residing in northern regions. Conclusion Appropriate measures are required to highlight the importance of chronic physical diseases and several socio-demographic factors that may negatively affect the trajectory of disability in older ages
