We compared gender disparities in later-life memory, overall and by education, in India and the United States (US).
Data (N = 7443) were from harmonized cognitive assessment protocols (HCAPs) in the Longitudinal Aging Study of India-Diagnostic Assessment of Dementia (LASI-DAD; N = 4096; 2017-19) and US Health and Retirement Study HCAP (HRS-HCAP; N = 3347; 2016-17). We derived harmonized memory factors from each study using confirmatory factor analysis. We used multivariable-adjusted linear regression to compare gender disparities in memory function between countries, overall and by education.
In the United States, older women had better memory than older men (0.28 SD-unit difference; 95% CI: 0.22, 0.35). In India, older women had worse memory than older men (−0.15 SD-unit difference; 95% CI: −0.20, −0.10), which attenuated with increasing education and literacy.
We observed gender disparities in memory in India that were not present in the United States, and which dissipated with education and literacy.
