Prevalence and Trend of Undiagnosed Hypertension (HTN) in the US from 1999 to 2010: An NHANES Study
Background: Hypertension remains one of the leading causes of coronary heart disease in the US. Early diagnosis and treatment are important for establishing preventive measures that can decrease the financial burden on our healthcare system.
Objectives: Describe the prevalence and trend of undiagnosed HTN cases from 1999 through 2010 and associated risk factors.
Methods: 18,264 participants aged 20 and older who completed continuous NHANES survey from 1999 – 2010, were never told they had HTN and non-pregnant women were included in this analysis. Constructing weights were used for nationwide estimates. Undiagnosed HTN was defined by systolic (≥ 140 mm) or diastolic (≥ 90mm) blood pressure measurements.
Results:The overall prevalence of undiagnosed HTN was 10.13%. There was a 4.23% decrease from 2000 (12.42%) to 2010 (8.19%). By gender: the males were 13.73% and the females 11.99%; by age: 32.27% in age 60+, 10.82% in age 40-59, and 4.23% in age 20-39; by race: the highest (14.57%) in Non-Hispanic Blacks, follow by Non-Hispanic White (13.39%), Mexican American (12.07%), other race (9.69%); by BMI: 14.94% for ≥ 30, 13.53% for 25-30, and 10.20% for < 25; by the ratio of family income to poverty: 13.25% for the lowest (< 1.3), 13.89% for the middle (1.3-3.5), 11.22% for the highest socioeconomic status.
Conclusion: Ten-year prevalence of undiagnosed HTN decreased by 34% remaining as high as 8.19%. One third of those over sixty years old were found to be hypertensive, yet were never diagnosed.
