[Epidemiological study of hypertension in Dongxiang population of Dongxiang county in Gansu province].
Objective:To investigate the prevalence, awareness, treatment and control rate of hypertension among Dongxiang population of Dongxiang county in Gansu province, and analyze risk factors of hypertension in this population.Methods:A total of 1 879 Dongxiang residents of Dongxiang county in Gansu province aged 18 years and over were selected in one town and eight villages by random cluster method from April to June in 2014. All subjects were interviewed and physical examination including blood pressure measurement was performed. Multivariate logistic regression analysis was used to analyze the risk factors of hypertension.Results:Prevalence of hypertension in this population was 21.4%(402/1 879). Prevalence of hypertension increased with aging and was 7.9%(35/441) in 18-39 years old people, and 20.2%(151/749)in 40-59 years old people, and 31.3%(216/689)in ≥60 years old people (P<0.01). There were no gender (male vs. female) difference in prevalence of hypertension in 18-39 years old group (8.0%(20/249)vs. 7.8%(15/192),P>0.05) and 40-59 years old group (19.8%(78/393) vs. 20.5%(73/356),P>0.05), while the prevalence of hypertension was significantly higher in male than in female(34.2%(123/360) vs. 28.3%(93/329),P<0.01)in ≥60 years old group. Prevalence of hypertension was also significantly higher in rural area residents than in county town residents (23.4%(255/1 090) vs.18.6%(147/789),P<0.01). The rates of awareness, treatment and control of hypertension in this population were 24.4%(98/402), 14.7%(59/402) and 5.0%(20/402), respectively. Rates of awareness (22.7%(58/255)vs. 27.2%(40/147),P<0.01), treatment(13.3%(34/255)vs. 17.0%(25/147),P<0.05) and control(3.9%(10/255)vs. 6.8%(10/147),P<0.05) were significantly lower in rural area residents than in county residents. Multivariate logistic regression analysis showed that age, family history of hypertension, high body mass index, less physical activity and more static state were risk factors of hypertension in this population(P<0.05 or 0.01).Conclusions:Prevalence of hypertension is high and awareness, treatment and control rates of hypertension are low in adult residents of Dongxiang county in Gansu province. Hypertension prevention focusing on risk factors control and treatment strategies should be enhanced in this population.
