Prevalence And Risk Factors For Prehypertension And Hypertension Among Adults In Central China From 2000-2011

Background:Hypertension is frequently studied by surveys,however,prehypertension,a new blood pressure status between normotension and hypertension,is rarely reported.Methods:All the data were derived from the China Health and Nutrition Survey(CHNS),and analyzed by logistic regression for correlation.Results:The prehypertension prevalence was 27.4%,with hypertension rate of 36.9%.The awareness,treatment,and uncontrolled rates among all hypertension were 19.8%,83.6%,and 55.0%respectively.The epidemic rate of hypertension increased with the increasing of ages(p<0.001),and the prehypertension appeared an epidemic peak in the age group of 38-57(p<0.001).In general,the incidence of hypertension in urban participants was higher than rural ones(p<0.001),and prehypertension in urban subjects was lower than rural ones(p<0.001).According to the results of logistic regression,the hypertension and prehypertension were associated with age,gender,location,Body Mass Index(BMI),Body Fat Rate(BFR),waist circumference(WC),education,and the intake of energy-yielding nutrient(p<0.05).Conclusion:The current work reveals a high epidemic rate of hypertension and prehypertension in central China,these results indicated the urgent need to develop strategies to improve prevention of hypertension and prehypertension in central China.
