Muscle strength, measured as grip strength is a potential marker of bodily function and sarcopaenia. Yet, not much is known about its patterns and correlates among older population in India. This study assesses the age and socioeconomic patterns and state variations in grip strength among older adults (50+) in India.
A cross-sectional and nationally representative data from the first wave of WHO's Study on global Ageing and Adult Health (SAGE) -2007 (n = 6262) was used. Multivariable linear regression analyses were used to understand the regional variations and association of socioeconomic status and general health with grip strength, adjusting for anthropometric and demographic confounders.
Socioeconomic status has a significant association with grip strength. Moreover, the association between wealth quintile and grip strength was highly significant. Further, the socioeconomic differences in grip strength narrowed in older ages, especially among men, supporting the convergence of health inequality hypothesis. Notable differences were observed in grip strength across selected states of India. Poor self-rated health was negatively associated with grip strength. Edentulism in men was associated with reduced grip strength.
This study has contributed to a better understanding of significant social and regional inequalities in grip strength among older population in India. State-specific and subgroup level interventions are important to improve the physical functioning of the growing older population in India.
肌肉力量，以握力衡量，是身体功能和肌肉减少症的潜在标志物。然而，对于印度老年人群中握力的模式及其相关性，我们知之甚少。本研究评估了印度老年人（50 岁以上）的握力在年龄和社会经济方面的模式和地区差异。
使用了世界卫生组织全球老龄化和成人健康研究（SAGE）第一波的横断面和全国代表性数据（n=6262）。使用多变量线性回归分析来理解社会经济地位和一般健康状况与握力之间的区域差异和关联，同时调整了人体测量和人口统计学混杂因素。
社会经济地位与握力有显著关联。此外，财富五分位数与握力之间的关联具有高度显著性。进一步，握力的社会经济差异在老年时缩小，尤其是在男性中，支持健康不平等趋同假说。在印度的一些选定邦中，观察到了握力方面的显著差异。自我报告的健康状况不佳与握力呈负相关。男性的失牙与握力下降有关。
本研究有助于更好地理解印度老年人群中握力方面的显著社会和地区不平等现象。针对特定邦和亚组的干预措施对于改善印度不断增长的老年人口的身体功能非常重要。
