Values are frequencies (percentages). Framingham 10‐year CVD risk scores were stratified into 3 mutually exclusive categories: low risk (<6%), intermediate risk (6–9.9%), and high risk (≥10%). CVD indicates cardiovascular disease; SCCS, Southern Community Cohort Study.

Crude frequency distributions of categorical variables among categories of CVD risk scores were compared using chi‐square tests.
