County-Level Hypertension Prevalence and Control in the United States: A ZIP3-County Crosswalk Using Electronic Health Record Data

PEER REVIEWED

Two map panels correspond to county-level hypertension prevalence and control in quartiles. The hypertension prevalence map (Map A) shows the following percentage ranges: 4.3%–48.6%, 48.7%–55.9%, 56.0%–63.2%, and 63.3%–91.2%. The hypertension control map (Map B) shows the following percentage ranges: 7.5%–25.1%, 25.2%–28.0%, 28.1%–31.7%, and 31.8%–56.0%. Hypertension is most prevalent and hypertension control least prevalent in counties in the southern states.

Prevalence of hypertension and hypertension control among US adult patients aged 18 years or older in 2022. Maps display county-level prevalence in quartiles of hypertension (Map A) and hypertension control (Map B) among adult patients in the IQVIA Ambulatory Electronic Medical Record-US database (1) in 2022. On Map A, the darker the color, the higher the hypertension prevalence, and on Map B, the darker the color, the lower the hypertension control prevalence among adults with hypertension. Suppressed counties (those with estimates that did not meet the National Center for Health Statistics rules) (2) were colored in dark gray on both maps.

This bivariate map displays hypertension prevalence and hypertension control in the 4 by 4 combinations based on the quartiles. Counties located in the Mississippi Delta, southern Texas, western Oklahoma, southwestern Arizona, northeastern Georgia, and southern Illinois had the highest hypertension prevalence but the lowest hypertension control.
