title: Life-course exposure to early socioeconomic environment, education in relation to late-life cognitive function among older Mexicans and Mexican Americans.
abstract: To examine the associations between life-course education and late-life cognitive function along with the modifying role of migration history.
  
  
  
  The combined sample includes 1,789 participants from the Sacramento Area Latino Study on Aging and 5,253 participants from the Mexican Health and Aging Study. Aged 60+ at baseline, participants were classified as Mexican residents, Mexicans-return migrants, Mexicans-immigrants to the United States, and Mexicans-U.S. born. Cognitive function was measured using standardized z scores of a short-term verbal recall test. Multivariate linear regression analysis was conducted.
  
  
  
  Participants' z scores were higher among those whose mother had more than elementary education (β = 0.28, p < .05). Participant's education mediated this association. For 5-year difference in education, the cognitive z score increased by 0.3 points for a U.S. born. Results were similar with father's education.
  
  
  
  Adult educational attainment mediates the effect of childhood socioeconomic status on late-life cognition. Migration plays a role in shaping cognitive aging.
