Abstract:

Objective To investigate the prevalence and associated risk factors of hypertension in Songnan community so as to provide evidence for the early prevention of hypertension. Methods Cluster sampling was employed, and questionnaire survey was performed in 10 185 residents aged above 40 years in Songnan community of Baoshan District. The questionnaires involved with hypertension and associated risk factors. Results The prevalence of hypertension was 49.9% in Songnan community of Baoshan District, and that of men was significantly higher than that of women (53.7% vs 47.3%）（P<0.0001）. The rates of hypertension awareness and control of this community were 70.2% and 23.7%, respectively. The prevalences of hypertension of men and women increased with age（P<0.0001）. Compared with those with normal body mass index (BMI), the prevalences of hypertension in patients with overweight and obesity were significantly increased (53.7% vs 36.3%, P<0.0001; 70.7% vs 36.3%, P<0.0001）. The prevalences of hypertension in patients with impaired fasting glucose and diabetes mellitus were significantly higher than those with normal glucose tolerance（64.5% vs 43.7%, P<0.0001; 71.2% vs 43.7%, P<0.0001）. Stepwise Logistic regression revealed that age, male, drinking, overweight/obesity, glycometabolism abnormality and high triglyceride level were independent risk factors of hypertension (P<0.05). Conclusion It is of utmost importance to take measures to prevent and treat hypertension in communities, especially in the elderly and those with overweight and obesity.
