Note: Model 1: age, education, and husband’s education. Model 2: age, education, husband’s education, as well as prevalent/history of high cholesterol, high blood pressure, diabetes, cancer, stroke, and myocardial infarction. Model 3: age, education, husband’s education, smoking status, physical activity, alcohol, body mass index, and the Alternative Health Eating Index (AHEI) diet index. Model 4: age, education, husband’s education, as well as prevalent/history of high cholesterol, high blood pressure, diabetes, cancer, stroke, and myocardial infarction, smoking status, physical activity, alcohol, body mass index, and the AHEI. CI = confidence interval; OR = odds ratio.
