  • NOTE: Of 2,301 men in the BACH study, 42 men were excluded from the analysis for taking medications likely to affect androgen levels or because they were under current treatment for cancer (29 men). Three hundred ninety-six men had missing values for hormones, and 22 men had hormone values more than 4 SDs from the mean of the natural log distribution and were excluded as outliers.

    Abbreviations: PASE, Physical Activity Scale for the Elderly; SES, socioeconomic status.

  • * Data were missing on covariates as follows: BMI (5), insurance status (6), socioeconomic status (97), marital status (10), alcohol use (2), activity (15), dyslipidemia (13), high blood pressure (6), diabetes (1), chronic lung disease (2), kidney disease (7), and arthritis (7). Bold indicates that the P value for a χ2 test of independence was <0.05. Comorbidities are any history of the condition, self-reported by the participant as diagnosed by a health care provider.

  • Overall weighted prevalence of statin use is 12.4% (95% CI, 10.3-14.9). All analyses were weighted by the inverse of the probability of being sampled. Thirteen statin users were on other cholesterol medications: bile acid sequestrants (1), fibric acid derivatives (4), and “miscellaneous” cholesterol medications (8).

  • Thirty nonstatin users were on other cholesterol medications: fibric acid derivatives (17) and miscellaneous cholesterol medications (13).

  • § As defined by any history of coronary artery bypass surgery or angioplasty, heart attack, angina, having a pacemaker, congestive heart failure, transient ischemic attack, stroke, carotid artery surgery, intermittent claudication, surgery or angioplasty for arterial disease of the leg, pulmonary embolism, aortic aneurysm, heart-rhythm disturbance, deep vein thrombosis, Raynaud's disease, or peripheral vascular disease.
