Abstract:
Objective To assess the prevalence, awareness, treatment, and control of hypertension among residents older than 15 years in Shanghai.
Methods A cross-sectional survey was conducted in 2010 in Shanghai by using structured questionnaires and blood pressure measurement. A total of 15 808 residents ( ≥ 15 years) were selected by a hybrid sampling strategy combining multi-stage sampling, stratified sampling and simple random sampling. And 15732 questionnaires were validated for study.
Results The average systolic blood pressure was 129.05 mmHg (95%CI:128.47-129.63mmHg), and the average diastolic blood pressure was 79.71 mmHg (95%CI:79.44-79.99 mmHg). The prevalence of hypertension was 31.15% (95%CI:29.79%-32.54%), the awareness rate was 74.19% (95%CI:71.93%-76.33%), the rate of receiving treatment was 59.95% (95%CI:57.58%-62.28%) and the blood pressure control rate was 30.59% (95%CI:28.32%-32.96%). The rates of awareness, treatment and control of hypertension were significantly higher in urban area than in rural area; and those rates were also significantly higher in female than in male (P < 0.01).
Conclusion The average values of blood pressure are high in Shanghai, and the prevalence of hypertension is attracting medical attention. Although a high rate of awareness is presented, the rates of treatment and blood pressure control are still low and need to be improved.
