Study design Data are from the Health and Retirement Study, a nationally representative, longitudinal survey of Americans age 51 and over. We used generalized estimating equations to examine trajectories and determinants of healthy ageing by level of education among 17,591 adults followed over a 14-year period. Educational level was categorized as less than a high school diploma, high school diploma, some college education, and a college or higher degree. Potential determinants included demographic factors, early-life characteristics (childhood health and childhood poverty), health-related factors (health behaviours, physical and mental health conditions), and psychosocial characteristics (perceived neighbourhood safety, volunteerism, and work status). Main outcome measures Informed by earlier work, we defined healthy ageing as freedom from cognitive impairment, freedom from disability, and high physical functioning. Results The log odds of healthy ageing declined over time in all educational groups. Importantly, the decline was smaller in adults with a college or higher degree than in those without a high school diploma. Age, gender, wealth, health behaviours, productive engagement, depressive symptoms, and the presence of chronic conditions predicted healthy ageing across the educational spectrum; however, the impact of several factors (age, gender, race/ethnicity, childhood poverty, and volunteerism) varied by educational level. Conclusions Education shapes trajectories of healthy ageing in the United States. Similarities and differences in determinants of healthy ageing are evident across levels of education. Findings highlight broad-based and education-specific targets for intervention. VL - 134 UR - http://www.sciencedirect.com/science/article/pii/S0378512219304414 ER -
