Age, sex, education, midlife vascular risk factors ref 1.02 (0.85, 1.24) ref 1.37 (1.01, 1.87)
Age, sex, education, midlife and late-life vascular risk factors ref 1.03 (0.85, 1.24) ref 1.40 (1.02, 1.91)

Notes: High IMR state defined as states with the highest quartile of state-level infant mortality rate in 1928. Midlife vascular risk factors are body mass index and high blood pressure. Late-life vascular risk factors are stroke and diabetes.
