Abstract 3672: Continuous Increase In Hypertension Prevalence In The United States: A 9-year Population-based Study
Background Hypertension is a major risk factor for cardiovascular disease, a leading cause of morbidities in the United States, and the number one cause of mortality. It has been estimated that nearly a third of all adult Americans suffer from hypertension signaling an overall increasing prevalence of the disease. The goal of this project was to analyze data collected by the National Health Interview Survey from 1997–2005 to assess the trend in hypertension prevalence over the 9-year period.
Methods A random stratified-cluster sampling design was used to draw data for the National Health Interview Survey (NHIS). We analyzed the 1997–2005 NHIS datasets with statistical software that incorporates sample weights, and stratification and clustering variables, permitting direct comparison of our calculated annual hypertension prevalence rates.
Results We the observed the following upward trend in the hypertension prevalence rate of the U.S. adult population during the studied 9-year period: 19.1; 19.0; 19.2; 19.4; 20.4; 21.1; 21.6; 22.1; and 22.4, consecutively. Across the 9-year span the population-adjusted prevalence rate rose more than 17%. The largest increase occurred between 2000 and 2001 when the rate increased 1% (19.4 to 20.4%).
Conclusion The results of this study corroborate earlier results from the National Health and Nutrition Examination Survey and the Behavioral Risk Factor Surveillance System, and provide a strong platform for launching public health measures to halt the propensity for high blood pressure among U.S. adults.
