Abbreviations: ARIC, Atherosclerosis Risk in Communities; BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); BPRHS, Boston Puerto Rican Health Study; CM, cardiometabolic; NA, not applicable.
SI conversion factors: To convert triglycerides to millimoles per liter, multiply by 0.0113; high-density lipoprotein cholesterol and total cholesterol to millimoles per liter, multiply by 0.0259; glucose to millimoles per liter, multiply by 0.0555; and hemoglobin A1c to proportion of total hemoglobin, multiply by 0.01.
Hypertension and dyslipidemia were defined as prescribed by cutoffs used to generate the cardiometabolic stress index. Prevalent cardiovascular disease was self-reported in the BPRHS and was defined as prior evidence of coronary heart disease, heart failure, and stroke in ARIC. Type 2 diabetes is defined in the text.
