Summary
This summary is machine-generated.

Women face higher lifetime dementia risk than men, with significant variations across racial and ethnic groups, particularly South Asian and Chinese populations. These disparities highlight the need to consider both sex/gender and race/ethnicity in dementia risk research.

Area of Science:

  • Gerontology
  • Epidemiology
  • Public Health

Background:

  • Dementia risk studies often neglect racial/ethnic disparities, especially in Asian American communities.
  • This study addresses sex/gender and racial/ethnic differences in dementia risk.

Purpose of the Study:

  • To compare sex/gender-specific lifetime dementia risk conditional on dementia-free survival to age 60.
  • Focuses on Chinese, Filipino, Japanese, South Asian, and non-Latino White older adults in California.

Main Methods:

  • Utilized a cohort study linking mailed surveys with electronic health records (EHR) from 2002-2020.
  • Included participants aged ≥60 years from specified racial/ethnic groups with no prior dementia diagnosis.
  • Employed the Aalen-Johansen estimator to calculate cause-specific cumulative incidence of dementia, accounting for death as a competing event.

Main Results:

  • Analyzed 159,477 participants across diverse racial/ethnic groups.
  • Lifetime dementia risk was higher in women (38%-49%) than men (28%-35%), varying by ethnicity.
  • Largest sex/gender differences observed in South Asian and Chinese participants; dementia-free mortality was higher in men.

Conclusions:

  • Lifetime dementia risk to age 60 is higher for women than men and differs significantly across racial/ethnic groups.
  • Disparities may be influenced by mortality rates and social/structural factors.
  • Emphasizes the intersectionality of sex/gender, race, and ethnicity in dementia risk.
