ABSTRACT

Objective To understand the prevalence and distribution of hypertension in population aged 15 years and over in Guizhou province and provide evidence for the prevention and management of hypertension.Methods Face to face interviews using national standard questionnaire were conducted among the study subjects selected in Guizhou through multi-stage random sampling.Blood pressure measurement for them was done with Omron HEM-1300 professional portable blood pressure monitor.SPSS 19.0 software was used for statistical analysis.The ratio was compared by the x2 test.The influencing factors of hypertension was analyzed by multivariate logistic regression analysis.Results A total of 13 480 participants were investigated,including 5 509 (40.8％) men and 7 971 (59.2％) women;6 558 (48.6％) urban residents and 6 922 (51.4％) rural residents.Among the subjects surveyed,3 232 (23.9％) were smokers,2 412 (17.9％) were alcoholic and 4 859 (36.0％) were obese or overweight.A total of 3 937 (29.2％) hypertension patients were found.The prevalence of hypertension was 29.2％.The standardized prevalence of hypertension were 18.97％ (compared with national population composition) and 21.16％ (compared with Guizhou province population composition),respectively.The hypertension prevalence in men and women were 29.8％ and 28.8％,respectively.The hypertension prevalence in rural population (35.8％) was higher than that in urban population (22.2％).The difference was statistically significant (P＜0.001).The hypertension prevalence in people aged 65 years and over was 56.2％.The prevalence of hypertension were 34.3％ and 27.6％ in smokers and non-smokers,39.2％ and 27.0％ in alcoholic and non-alcoholic and 40.7％ and 22.7％ in obese or overweight group and normal or less weight group,respectively.There were significant statistical differences in prevalence of hypertension among the population in urban area and rural area,with different age,education levels,smoking status,drinking status and BMI (P＜0.001).Conclusions The prevalence of hypertension in Guizhou was at a high level.The hypertension prevalence in rural area was higher than that in urban area.Hypertension prevalence increased significantly with age.The prevalence of hypertension was negatively associated with the education level of the people.Older age,living in rural area,smoking,drinking,obesity were the risk factors for hypertension.
