成人肥胖测量指标与高血压患病关系

目的探讨成人肥胖测量指标与高血压患病的关系。方法利用江苏省2010年成人慢性病及其危险因素监测数据,描述新发现高血压患者在不同人群中的分布差异;运用双变量相关和非条件Logistic回归方法,分析体质量指数(BMI)、腰围、腰身比和体脂百分比等肥胖测量指标与血压及高血压患病的关系。结果江苏省成人新发现高血压患病率为35.3%,男性高于女性,患病率随年龄增长呈上升趋势(P0.05)。双变量相关分析结果表明,BMI、腰围、腰身比和体脂百分比等肥胖测量指标与收缩压和舒张压均成正相关。多因素非条件Logistic回归分析结果显示,肥胖(χ2=129.67,P0.05)、中心型肥胖(χ2=157.05,P0.05)、BMI(χ2=176.21,P0.05)、腰围(χ2=187.73,P0.05)、腰身比(χ2=221.49,P0.05)和体脂百分比(χ2=155.22,P0.05)均与高血压患病显著相关;BMI、腰围、腰身比和体脂百分比每增加1个标准差(SD),高血压患病风险分别增加59%(OR=1.59,95%CI:1.50~1.70)、60%(OR=1.61,95%CI:1.50~1.71)、68%(OR=1.68,95%CI:1.57~1.79)和149%(OR=2.49,95%CI:2.21~2.80)。BMI、腰围、腰身比和体脂百分比等肥胖测量指标对高血压患病风险的影响依次升高。结论 BMI、腰围、腰身比和体脂百分比与高血压患病相关,高血压患病风险随肥胖程度的增加而升高。

Relationship between adiposity and the prevalence of hypertension in adults

Objective To explore the relationship between the parameters of adiposity and the prevalence of hypertension in adults. Methods The data of ＂Jiangsu Provincial Surveillance on Chronic Diseases and Risk Factors＂ of 2010 was used to describe the distributional difference of the prevalence of new hypertension in different population. The relationship between the parameters of adiposity and the blood pressure, the prevalence of hypertension was analyzed by bivariate correlation analysis and unconditional logistic regression analysis. Results The prevalence of new hypertension was 35.3%, which was higher in male than that in female. The prevalence showed an obvious rising trend with the increase of age. The results of bivariate correlation analysis showed that BMI, waist circumference, waist-height ratio and percentage of body fat had positive correlation with both systolic and diastolic blood pressure. The results of unconditional logistic regression anal- ysis showed that obesity （χ^2 = 129. 67, P〈0. 05 ）, central obesity （χ^2 = 157. 05, P〈0. 05 ）, BMI （χ^2 = 176. 21, P〈0. 05）, waist circumference （χ^2 = 187.73, P〈0. 05 ）, waist-height ratio （χ^2 = 221.49, P〈0. 05 ） and percentage of body fat （χ^2 = 155.22,P〈0. 05）, were significantly associated with hypertension. 1-SD increase of BMI, waist circumference, waist-height ratio and percentage body fat increased the risk of hypertension by 59% （ OR= 1.59, 95%CI：1.50-1.70）, 60% （ OR= 1.61, 95%CI： 1.50-1.71）, 68% （OR= 1.68, 95%CI： 1.57-1.79） and 149% （ OR= 2. 49, 95% CI： 2. 21-2. 80）. The influencing degree to hypertension increased in turn with the influence of BMI, waist circumference, waist-height ratio and percentage body fat. Conclusions BMI, waist circumference, waist-height ratio and percentage of body fat show great influences on the prevalence of hypertension. The risk of hypertension will increase with the increase of obesity degree.
