Objective To evaluate the prevalence, awareness, treatment and control of hypertension and risk factors in communities of Changchun in Jilin province of China.

Methods A multistage cluster sampling method was used to investigate the prevalence of hypertensionin. The survey contained a standard questionare, biochemical tests and physical examinations. Logistic regression analysis was used to identify risk factors of hypertension.

Results Of 2175 (male = 1129) subjects, the overall prevalence of hypertension is 44.46% in communities of Changchun in China, the awareness, treatment and the control is 22.34%, 16.65%, 0.83%, respectively. For male, the prevalence, awareness, treatment and control is, respectively, 24.05%, 9.93%, 7.34% and 0.10%; And for female is 20.41%, 12.41%, 9.30% and 0.72%. The overweight and obese people has a higher prevalence (P < 0.001), awareness (P = 0.003), and treatment (P < 0.001) of hypertension, but no significance in control. People with high-salt diet has a higher prevalence (P < 0.001) than people with low-salt diet; And there are no significance for people with more meat, vegetables, sweet diet or between white-collar and blue-collar. In a binary logistic regression, old age, drink, high-salt diet, central obesity, family history of hypertension, DM and dyslipidemia were associated with increased odds of the hypertension, and the odd ratio is 1.06, 1.51, 1.39, 2.47, 1.78, 1.50 and 1.63, respectively but no significance differernce with physical activity, monthly income, high carbohydrate intake and education.

Conclusions The prevalence of hypertension is high in in communities of Changchun in Jilin province than the southern China but the awareness, treatment especially control is lower than the other areas.
