Background: Hypertension is a well-known risk factor for cardiovascular disease. The purpose of this study is to explore the distribution of blood pressure and the prevalence of hypertension in Taiwan from 2000 to 2002, and establish the data base for the evidence-based medicine. Method: This was a hospital-based, descriptive study. We retrospectively analyzed the patients receiving periodic health checkups at China Medical University Hospital from January 2000 to December 2002. Totally 3,392 patients were enrolled in this study, divided into three age groups, 20-39, 40-64 and ≥65. Subjects were considered to have hypertension if the average of both hand readings exceeded 140 mmHg systolically and/or 90 mmHg diastolically, or subjects with hypertensive history. The One-way ANOVA test and the chi-square test were used. Result: There were 1,450 women (42.7%) and 1,942 men (57.3%). The mean age was 49.3±12.3 years (age range 20-87 years). Overall, the prevalence of hypertension was 28.8% (25.0% women and 31.6% men, p<0.001). Corresponding to age groups 20-39, 40-64 and ≥65, the prevalence of hypertension was 2.3%, 25.1% and 57.1% in women (p<0.001), and 15.0%, 34.1% and 50.8% in men (p<0.001), respectively. Among diabetic people, 44.5% of women and 54.2% of men were not aware of hypertension diagnosis. Conclusions: The prevalence of hypertension remains relatively high among the Taiwanese adults in 2000-2002. Policy and programs to intervene hypertension must be substantially intensified. We hope this study could provide basic information for further studies on the evidence-based medicine of hypertension in Taiwan.
