Abstract:Objective
To understand  the prevalence of hypertension and selenium intake of the residents in rural areas of Jilin province,and to discuss the relationship between selenium intake and the prevalence of hypertension, and to provide reference for prevention and therapy of  hypertension.Methods A total of 1 380 inhabitants in rural areas of Jilin province were selected by way of cluster sampling to conduct dietary investigation,physical and blood examination.The selenium intake was categorized into three groups according to tritiles after adjusted by energy,and the relative risk for incidence of hypertension in each group was estimate by using the Logistic regression model with the first group as the reference.Results The prevalence ofhypertension in the study area was 37.4%. The average for selenium intake was 35.908 μg?d-1 and was lower than the standard level of selenium recommended by  RNI.After adjustment for other risk factors,the relative risk for incidence of hypertension for different selenium intakes in the  men was 1.00,0.471（95%CI 0.290－0.765）,and 0.596（95%CI 0.373－0.951）,the P values were 0.002 and 0.030.There was no significant relationship between selenium intake and the incidence of hypertension in the  women,and there was also no significant relationship between Han people and Korean people in China.Conclusion The selenium intake is the influencing factor affecting the incidence of hypertension of the male rural residents in Jilin province,which reminds that the increasing selenium intake is helpful for the prevention of male hypertension.
