ABSTRACT
Objective:To study the influence of different dietary patterns in hypertension, and to provide references for establishing a healthy dietary pattern, improving the abnormal blood pressure, preventing the early hypertension and controlling the high blood pressure.Methods:Random cluster sampling was adopted to analyze the dietary,examine the physical situations,and measure the blood pressures among 1 394 residents of Han nationality and Korean nationality aged from 40 to 80 years old from 8 villages in Jinlin Province from 2010 to 2011.Factor analysis was used to establish the dietary patterns and to analyze the effects of different dietary patterns on the prevalence of hypertension.Results:The prevalence of hypertension of middle aged and elderly people in the rural areas of Jilin Province was 35.3%.4 dietary patterns were obtained through factor analysis,including salted product dietary pattern,alcohol dietary pattern,condiments dietary pattern and high protein dietary pattern.By multivariate Logistic regression analysis and adjustment of the age,the gender,the nationality,the education and the career background, alcohol dietary pattern was positively correlated with the occurrence of the hypertension (OR=1.43,95%CI 1.07-1.90).Conclusion:Alcohol dietary pattern is closely related to the hypertension. Long-time large amount of alcohol is a risk cause for high blood pressure. Reducing alcohol consumption and developing healthy diet habits can help to prevent hypertension.
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 of hypertension in the study area was 37.4%.The average for selenium intake was 35.908μg·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.
