Age, sex, education ref 1.01 (0.84, 1.22) 1.43 (1.27, 1.61) 1.93 (1.44, 2.61)
Age, sex, education, midlife vascular risk factors ref 1.02 (0.85, 1.24) 1.34 (1.19, 1.51) 1.84 (1.37, 2.49)
Age, sex, education, midlife and late-life vascular risk factors ref 1.03 (0.85, 1.25) 1.36 (1.20, 1.53) 1.92 (1.42, 2.59)

Notes: High IMR state defined as 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.
