OBJECTIVE
To explore the epidemiological features of prehypertension in community of Changsha and its relevant risk factors.


METHODS
A total of 15 000 participants from 5 communities in Changsha were surveyed by randomly stratified cluster sampling. The questionnaire interviews and physical examination were conducted for these people, and their serum biochemical indexes were also collected and analyzed.


RESULTS
The prevalence of prehypertension was 34.6%. The prevalence for males was higher than that in females (44.7% vs 21.7%, P<0.01). The prevalence for males was declined in older age, but for females was increased. Central obesity, age, overweight, male, drinking, smoking, high-level total cholesterol, high-level triglyceride, high-level density-lipoprotein cholesterol, low-level density-lipoprotein cholesterol, high-level fasting blood glucose, high-level creatinine, high-level uric acid were the risk factors for prehypertension, while high level of education was a protective factor.
