Hypertension was defined as reported history of high blood pressure, systolic blood pressure greater than 140 mmHg, diastolic blood pressure or 90 mmHg, or use of antihypertensive medication. Dyslipidemia was defined as a history of hyperlipidemia or total cholesterol greater than 240 mg/dL. Diabetes was defined as a history of diabetes or fasting blood sugar greater than 126 mg/dL. Coronary artery disease was defined as having a history of bypass surgery, angioplasty, or myocardial infarction.
For the discrete traits, significant differences between men and women were tested using a Chi-Square statistic. For the continuous traits, significant differences between men and women were tested using the Wilcoxon Rank Sum test.
