Objective:
To assess the epidemiology features of hypertension in Heilongjiang Province, China.
Methods:
From 1959 to 1999, 289,157 people in total, ages > or = 15-year old (male 154,091, female 135,066) were investigated four times by a stratified chunk method in rural and urban areas in Heilongjiang Province. After a staff training program, this survey on blood pressure and risk factors was carried out under a worldwide uniform protocol with standardized method and interrelated quality control regulation. Among these samples, 1615 people (male 824, female 791) received blood-lipid analysis.
Results:
The hypertensive incidence of Heilongjiang was much higher than the average level in China (P < 0.01) and it has gotten higher from 1959 to 1999, especially in the last ten years. It increased more in males than in females (P < 0.01). It was also higher with age. The mean age of hypertensive onset became ten years younger recently. It is different in different areas and professions. Age, BMI (body mass index), drinking alcohol, gender, history of maternal hypertension, high salt diet and professional status were the main risk factors for hypertension in Heilongjiang Province in China.
Conclusion:
The prophylaxis and treatment of hypertension should be enhanced in this area.
