Values are reported as number (%) unless otherwise indicated. The relative economic levels categorized into 10 levels according to their health insurance premiums. CVH indicates cardiovascular health; and IQR, interquartile range.
*
The CVH metrics included nonsmoking, body weight, physical activity, blood pressure, fasting blood glucose, and total cholesterol.
†
The continuous 12‐point CVH score (range, higher score indicating higher CVH) was calculated by assigning 0 (poor), 1 (intermediate), and 2 (ideal) points to each of the 6 metrics and summing them.
