Abstract
INTRODUCTION
We compared gender disparities in later-life memory, overall and by education, in India and the United States (US).
METHODS
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.
RESULTS
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.
CONCLUSION
We observed gender disparities in memory in India that were not present in the United States, and which dissipated with education and literacy.
