Associations between neighbourhood safety, social cohesion, sleep quality and sleep duration among older adults in India: Findings from the Study on Global Aging and Adult Health (WHO-SAGE), 2015.

BACKGROUND: Most studies on later-life health in India focus on families, with far less attention given to the health repercussions of neighbourhood conditions among older Indians. We address this limitation in existing research by examining the associations between perceptions of neighbourhood safety and social cohesion and sleep duration and sleep quality among older adults in India. METHODS: Data come from the Study on Global Aging and Adult Health (WHO-SAGE), India 2015 wave 2, with a sample of 7118 adults aged 50 years and above. Sleep quality and duration were assessed using subjective responses. Multivariable logistic and linear regression analyses were employed to test the research hypotheses. RESULTS: Prevalence of poor sleep quality was higher among older adults living in unsafe neighbourhoods (4.46%) than peers residing in safe neighbourhoods (3.52%), and it was also higher among those living in neighbourhoods with poor social cohesion (5.31%) than counterparts who lived in socially cohesive communities (3.10%). Older adults in neighbourhoods with poor social cohesion had higher odds of reporting compromised sleep quality (adjusted odds ratio 1.75, CI: 1.22-2.51) than those living in socially cohesive neighbourhoods. Moreover, compared to those who perceived they were living in safe neighbourhoods, their peers who perceived their neighbourhoods as unsafe reported shorter sleep duration, with a negative beta coefficient of -0.27 (CI: -0.45 to -0.085). CONCLUSION: That perceived unsafety and poor social cohesion within one's neighbourhood are associated with compromised sleep reflects the significance of making neighbourhoods safer and more integrated for later-life sleep health. In addition to micro-level strategies (e.g., balanced nutrition and physical activity), efforts to improve sleep health should optimise macro-level opportunities, such as rehabilitating and revitalising neighbourhoods, which may alleviate sleep disturbances and improve sleep outcomes among older adults.

Population Aging in India: A Micro-Level Estimate Using Gridded Population Data.

As population aging continues to become a major demographic trend globally, it is essential to examine the demographic shifts at the micro-level to understand the changing scenario of older populations. A lack of adequate data in India on older populations is a hindrance to the government's efforts to provide social security for them. This study uses gridded population data to analyze the spatial patterns, micro-level trends, and the share of older populations in India for 2030 and 2040. The study's findings demonstrate that India has seen a dramatic shift in population aging trends, with large intra-state variability. The micro-level analysis shows that certain districts have a higher percentage of older people. Further, the share of older populations is predicted to rise considerably over the next two decades. The results highlight the need to shift from national and state-level policies to a more localized approach. The findings provide a comprehensive analysis of population aging at the micro-level in India and highlight the need for targeted policies and programs to ensure the well-being of older populations. The results of this study can inform policymakers in their efforts to provide social security for older people and improve their quality of life.
