Incidence And Predictors Of Hypertension Among Rural Chinese Adults: Results From Liaoning Province

PrefaceHypertension is a common and frequently encountered disease.Hypertension is also an important risk factor for death,stroke and cardiovascular disease.Hypertension is an important modifiable risk factor for cardiovascular disease and total mortality.At present,Intervention of the incidence of hypertension is a major strategy to prevent and control cardiovascular disease.Because over one half of the Chinese populations live in rural regions,the prevalence of the hypertension in rural regions is direct to influence all nation's epidemic of stroke and cardiovascular disease.Studies published in the 1980s and 1990s suggested that the prevalence and incidence of hypertension in rural China was very low.However,China,in general,and rural China,in particular,has been undergoing rapid social changes during the past two decades.These changes are occurring a rapid acceleration in the number of cases of hypertension in rural China.Because of the status of a rapid acceleration in the number of cases of hypertension in rural China.this study make a prospective study to assess incidence and predictors of hypertension among rural Chinese adults.ObjectiveThe objective of this study was to assess the incidence of hypertension and its risk factors among rural of liaoning province adults.and to provide scientific basis for preventing and intervene measurement of hypertension in the rural area for government.MethodsA population-based sample of 24 360 rural Chinese adults aged≥35 years and free from hypertension at baseline were followed from 2004～2006 to 2008.mean of 28 months of follow-up.Assess incidence and predictors of hypertension among rural Chinese adults. ResultsOver a mean of 28 months of follow-up,29.6%of men and 23.4%of women developed hypertension.The age-adjusted incidence rate was higher in men(12.75 per 100 person-years) than in women(10.04 per 100 person-years).Among men, independent predictors of incident hypertension were baseline age[relative risk(RR) per 5 years:1.124;95%confidence interval(CI):1.108,1.141,p＜0.001],Mongolian ethnicity(RR:1.093;95%CI:1.011,1.181,p=0.025),use of alcohol,(RR:1.147;95% CI:1.066,1.234,p＜0.001),overweight and obesity(RR:1.257;95%CI:1.166,1.394, p＜0.001),family history of hypertension(RR:1.132;95%CI:1.020,1.256,p=0.019), baseline salt intake(RR per one g/day:1.003;95%CI:1.000,1.005,p=0.024) and prehypertension versus normotension(RR:1.174;95%CI:1.082,1.274,p＜0.001). Among women,With the exception of use of alcoho as risk factors in women;the results were similar to men.The awareness,treatment and control rates for newly developed hypertension were 29.9%,19.5%and 1.5%respectively.ConclusionsThese data indicate that the incidence of hypertension is high among these rural Chinese adults and The awareness,treatment and control rates for newly developed hypertension is low.among men the incidence of hypertension was higher than women. The incidence of hypertension was also higher in those of Mongolian ethnicity than that in those of Han ethnicity。The incidence of hypertension was higher with higher baseline age group or higher baseline BP group for both men and women.
