Does education moderate gender disparities in later‐life memory function? A cross‐national comparison of harmonized cognitive assessment protocols in the United States and India.

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. [ABSTRACT FROM AUTHOR]
