Means and SDs are provided for the first seven measures in the table, percentages for the remaining five measures.
High triglycerides: triglycerides ≥ 150 mg/dl.
High BP: SBP ≥ 130 mmHg or DBP ≥ 85 mmHg, or current blood pressure medication use.
Impaired glucose: fasting blood glucose ≥ 110 mg/dl or classification as diabetic.
Low HDL: HDL cholesterol level < 50 mg/dl.
Abdominal obesity: waist circumference ≥ 80 cm for Chinese and Japanese women, ≥ 88 cm for Caucasian, Hispanic and African-American women.
Varying amount of missing data on each variable; complete data on age.
BP, blood pressure; DBP, diastolic blood pressure; HDL, high-density lipoprotein; SBP, systolic blood pressure; SD, standard deviation.
