Individual and Neighborhood Influences on the Relationship Between Waist Circumference and Coronary Heart Disease in the REasons for Geographic and Racial Differences in Stroke Study
ORIGINAL RESEARCH — Volume 19 — April 21, 2022
PEER REVIEWED
The REGARDS study sample had 30,239 participants. We excluded those with consent errors (n = 56), a baseline history of stroke or CHD (n = 6,624), missing or invalid zip code (n = 8), missing values for waist circumference (n = 137), or erroneous values for waist circumference (n = 18), and participants lost to follow up (n = 354).

These line graphs show Kaplan-Meier incident coronary heart disease event estimates for the 4 quartiles of waist circumference among the total study sample, White men, White women, African American men, and African American women. In the total sample, White men, White women, and African American women in the highest quartile for waist circumference had higher rates of incident coronary heart disease. Among African American men, there were no differences in waist circumference quartiles with respect to incident coronary heart disease.
