Abstract

Purpose: Since the publication of the 2017 ACC/AHA hypertension guideline, few studies have analyzed the epidemiology and management of hypertension across many heterogeneous subgroups in the US.

Materials and methods: We analyzed the data collected by the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2016. Participants greater than 20 years of age, who had valid blood pressure measurements, were included in the study. A comprehensive analysis of 14 population subgroups was done to systematically examine how hypertension awareness, treatment, and control varied by subpopulations.

Results: Our study included 45,557 participants with a mean age of 47.1 years, 48.3% were male and 51.7% were female. 47.8% participants had hypertension, of which 59.9% were aware of their diagnosis. Among the participants who were aware of their hypertension, 90.3% were prescribed medication(s) to lower blood pressure, of which 39.2% had achieved control. Multivariate analysis showed age, gender, Race/ethnicity, annual family income, education level, BMI, waist to height ratio, diabetes, and previous cardiovascular events to be independent risk factors for hypertension. Lower likelihoods of awareness and treatment were associated with male sex, younger age, Mexican ethnicity, participants without health insurance, absence of previous cardiovascular events, diabetes, obesity, or smoking. Overall, hypertension control rate was suboptimal across most of subgroups (<40%).

Conclusion: Based on the 2017 ACC/AHA guideline, almost half of the US adult population has hypertension. The suboptimal number of people with controlled blood pressure is pervasive in all subgroups and warrants greater efforts in prevention, as well as more effective treatment.
