Abstract: Objective To assess the relationship between hypertension and BMI,waist circumference and waist-hip ratio in middle-aged and elderly residents in Luzhou,Sichuan province.Methods A total of 2 033 middle-aged and elderly local residents aged 35-69 years were enrolled from Luzhou through stratified cluster sampling from March 27 to April 20,2015.A face-to-face questionnaire survey and physical examination were conducted by trained investigators.Results The overall prevalence rate of hypertension was 43.48％.The overweight rate,obesity rate,centrality obesity (calculated according to waist circumference) and centrality obesity (calculated according to waist-hip ratio) were 42.5％,14.6％,48.4％ and 74.0％,respectively.The multivariate logistic analysis showed that gender and age were related to the prevalence of hypertension.Compared with age group ＜40 years,the OR values were 2.066 and 4.756 respectively in age groups 45-60 and ≥60 years.After control the confounding effect of gender and age,overweight,obesity and centrality obesity (calculated according to waist circumference) were risk factors for hypertension,waist-hip ratio was not used in the regression equation.BMI and waist circumference or waist-hip ratio had combined effect on the prevalence of hypertension.Compared with the normal adults,the risk for hypertension increased as the increase of the level of overweight and obesity [OR from 1.524 (95％CI:1.044-2.226) to 4.461 (95％CI:3.405-6.326) and OR from 1.569 (95％CI:1.134-2.171) to 5.468 (95％CI:3.797-7.876)].Conclusions The influences of BMI,waist circumference and waist-hip ratio on the prevalence of hypertension were significant,but the influence of waist circumference on hypertension was greater than waist-hip ratio.Keeping normal bodyweight might be one of the effective hypertension prevention measures.
