Prevalence, awareness, treatment, and control of hypertension among residents in the severe historical endemic areas of Keshan disease in Heilongjiang Province / 中华地方病学杂志

ABSTRACT

Objective To describe the status of prevalence,awareness,treatment,and control of hypertension among the residents in severe historical endemic areas of Keshan Disease in Heilongjiang Province,and to provide scientific evidence for prevention and control of hypertension.Methods In December 2015,Yongjin,Yongli groups of Yongjin Village,and Fengnian,Fengtian,Fengfu groups of Fengnian Village in Fanrong Township,Fuyu County,Qiqihaer City,Heilongjiang Province were selected via the cross-sectional method.The residents aged 18 years or older were surveyed as respondents by cluster sampling.Demography,risk factors,hypertension related information were collected through questionnaire survey.Blood pressure,height and weight were measured through physical examination.Blood pressure measurement was conducted with Omron HEM-1020 electronic sphygmomanometer,the diagnostic criteria was Chinese Guidelines for Prevention and Treatment of Hypertension (revised in 2010).Results Totally 683 residents were surveyed,the valid participants were 669,the prevalence of hypertension was 49.2％ (329/669),the standardized prevalence was 37.9％,the prevalence of men [58.0％ (164/283)] was higher than that of women [42.7％ (165/386),x2 =15.103,P ＜ 0.01],the prevalence increased with increasing age (total,men,womenx2tendency =9.044,4.560,7.789,all P ＜ 0.01).The awareness of hypertensive patients was 60.8％ (200/329),the standardized awareness was 41.2％,the awareness of men [54.3％ (89/164)] was lower than that of women [67.3％ (111/165),x2 =5.836,P ＜ 0.05],the awareness of hypertensive patients increased with increasing age (total,men,womenx2tendency =3.638,2.686,2.419,all P ＜ 0.05).The treatment of hypertensive patients was 51.1％ (168/329),the treatment of men [43.9％ (72/164)] was lower than that of women [58.2％ (96/165),x2=6.711,P ＜ 0.05],the treatment of hypertensive patients increased with increasing age (total,men,womenx2tendency =4.422,2.704,3.633,all P ＜ 0.01).The control rate of hypertensive patients was 5.5％ (18/329),the control rate among the treatment was 10.7％ (18/168).Conclusions The standardized prevalence of hypertension among the residents of the severe historical endemic areas of Keshan disease in Heilongjiang Province is higher than the national average (25.2％),the standardized awareness is lower than the national average (46.5％),the treatment and the control are low.We should pay more attention to the hypertension in the severe historical endemic areas of Keshan disease.
