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.

Objective To explore the prevalence,awareness,treatment and control rates of hypertension among Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province,and to analyze risk factors of hypertension in this population.Methods A total of 984 (aged 18 and over) Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province were included with cluster sampling method from March to June,2014.General information was obtained by questionnaire and blood pressure was measured.Multivariate logistic regression analysis was applied to analyze the risk factors of blood pressure.Results Prevalence of hypertension in this population was 19.3％ (190/984),and standardized prevalence rate was 21.7％.The prevalence of hypertension were 16.3％ (82/502),21.0％ (60/286) and 24.5％ (48/196),and standardized prevalence rate was 17.8％,22.1％ and 26.6％ among Tibetan monks aged 18-39,40-59 and ≥60 years,respectively.Rates of awareness,treatment and control of hypertension in Tibetan monks were 9.5％ (18/984),4.2％ (8/984)and 1.6％ (3/984),respectively.Multivariate logistic regression analysis showed that age,body mass index and family history of hypertension were independent risk factors of hypertension in this population (P ＜ 0.01 or 0.05).Conclusions Prevalence,awareness,treatment and control rates of hypertension among Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province are relatively low.Age,body mass index and family history of hypertension are risk factors of hypertension in this population.
