title: [Relationship between hypertension and body mass index, waist circumference and waist-hip ratio in middle-aged and elderly residents].
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, theORvalues 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 [ORfrom 1.524 (95%CI: 1.044-2.226) to 4.461 (95%CI: 3.405-6.326) andORfrom 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.
