Abstract:

Objective To investigate the  blood pressure level and  the prevalence and distributional characteristics of hypertension among the adults in Jilin province and to provide evidence for making  preventive and controlling strategies against hypertension.Methods A total of 20 473 adults aged 18-79 years old from Jilin province were selected by multistage cluster randomly sampling.Medicial examination and face-to-face questioning survey were conducted to collect the information about hypertensive distribution.Blood pressure was examined by electronic blood pressure monitor.According to complex sampling plan and post-stratification,the resultant data were weighted to estimate the level of blood presure and the prevalence rate.Results  The weighted average systolic blood pressure and diastolic blood pressure were (128.1±20.2) mmHg and (78.4±11.6) mmHg,respectively. The weighted prevalence rate of hypertension was 30.5%(95%CI：29.7%-31.2%). The prevalence rate was increased with age. The prevalence rate of the males (34.4%，95%CI：33.3%-35.6%) was statistically higher than that of the females(26.3%，95%CI：25.3%-27.2%) (P<0.01).The prevalence rates  of hypertension in easten region (33.2%，95%CI：31.4%-35.1%) and western region (32.4%，95%CI：30.5%-34.3%) were higher than that in central region (29.0%，95%CI：28.1%-29.9%) (P<0.01).There was nosignificant difference between the prevalence of hypertension in urban area (30.4%，95%CI：29.3%-31.4%) and rural area (30.6%，95%CI：29.6%-31.7%) (P>0.05).Conclusion In 2012,the prevalence rate of hypertension among the  adult residents in Jilin province is higher than before.There are differences in the distributional characteristics of hypertension among variations by age,gender and geographic regions.Health system should prevent and control hypertension according to the epidemiological characteristics.
