To examine gender disparities in cognitive functioning in India and the extent to which education explains this disparity in later life.
This study uses baseline interviews of a prospective cohort study of 1,451 community-residing adults 45 years of age or older in four geographically diverse states of India (Karnataka, Kerala, Punjab, Rajasthan). Data collected during home visits includes cognitive performance tests, and rich sociodemographic, health, and psychosocial variables. The cognitive performance tests include episodic memory, numeracy, and a modified version of the Mini-Mental State Examination.
We find gender disparity in cognitive function in India, and this disparity is greater in the north than the south. We also find that gender disparities in educational attainment, health, and social and economic activity explain the female cognitive disadvantage in later life.
We report significant gender disparities in cognitive functioning among older Indian adults, which differ from gender disparities in cognition encountered in developed countries. Our models controlling for education, health status, and social and economic activity explain the disparity in southern India but not the region-specific disparity in the northern India. North Indian women may face additional sources of stress associated with discrimination against women that contribute to persistent disadvantages in cognitive functioning at older ages.
研究印度认知功能方面的性别差异,以及教育在多大程度上解释了晚年的这种差异。
本研究采用了一项前瞻性队列研究的基线访谈,该研究涉及印度四个地理区域不同的邦(卡纳塔克邦、喀拉拉邦、旁遮普邦、拉贾斯坦邦)的1451名45岁及以上的社区居住成年人。家访期间收集的数据包括认知能力测试,以及丰富的社会人口统计学、健康和心理社会变量。认知能力测试包括情景记忆、算术能力,以及简易精神状态检查表的一个修订版本。
我们发现印度在认知功能方面存在性别差异,且这种差异在北方比南方更大。我们还发现,在教育程度、健康状况以及社会和经济活动方面的性别差异解释了女性在晚年的认知劣势。
我们报告了印度老年成年人在认知功能方面存在显著的性别差异,这与发达国家所遇到的认知方面的性别差异不同。我们控制教育、健康状况以及社会和经济活动的模型解释了印度南部的差异,但没有解释印度北部特定地区的差异。印度北部的女性可能面临与对女性的歧视相关的额外压力源,这些压力源导致她们在老年时认知功能持续处于劣势。
