Abstract

We aimed to examine the trend in the prevalence of hospitalization attributable to hypertensive disease and its subtypes among United States adults aged ≥35 years from 1980 to 2007. Data (n = 4,598,488,000 hospitalized cases) from the National Hospital Discharge Surveys were used to examine the trends of hospitalized patients with first (the reason for admission) and patients with any second to seventh (a co-morbid condition when admission) diagnosis of hypertensive disease (International Classification of Disease, 9th Revision, Clinical Modification: 401 to 405) by gender and geographic region. Age-adjusted rates of disease were calculated using the United States 2000 standard population. The results show that age-adjusted hospitalization rates due to first diagnosis of hypertensive disease increased from 1.74% to 2.06% in men (p <0.01), and from 2.0% to 2.09% in women (p = 0.06) from 1980 to 1981 to 2006 to 2007. Age-adjusted rates due to any second to seventh diagnosis of hypertensive disease significantly increased from 7.06% to 35.09% in men (p <0.001), and from 7.88% to 31.98% (p <0.001) in women from 1980 to 1981 to 2006 to 2007. Patients with second to seventh diagnosis of essential hypertension and hypertensive chronic kidney disease had the highest and the second highest annual percent increases. Subjects living in the Southern region of the United States had the highest prevalence of hospitalization due to any second to seventh diagnosis of hypertensive disease compared with all other regions in 2006 to 2007. In conclusion, the prevalence of hospitalization due to hypertensive disease significantly increased in the United States from 1980 to 2007.
