目的了解天津市城乡居民超重、肥胖流行现状及其与血压的关系,为超重和肥胖的防控提供科学依据。方法采用多阶段分层随机抽样方法,抽取天津3个城区、3个郊区共12 600名≥15岁的常住人口为调查对象,进行现场问卷调查和体格检查,内容包括人口学特征、生活方式及疾病史等信息,并测量身高、腰围、体重和血压,计算体质指数(BMI)和腰围身高比(WHtR)。用SPSS 20.0统计软件进行t检验、方差分析、χ~2检验、相关分析及logistic回归分析。结果最终共调查12 474人(占调查总人数的99%),超重3 980例(31.9%),肥胖1 770例(14.2%),WHt R≥0.5者6 899例(55.3%);超重或肥胖、中心性肥胖指标在性别、年龄、城乡之间差异均有统计学意义(P<0.01);超重或肥胖、中心性肥胖患者的血压均值及高血压患病率均超过体重正常者,差异均有统计学意义(P<0.01);相关性分析结果显示,BMI和WHt R与收缩压(SBP)、舒张压(DBP)均呈正相关(r值分别为0.300、0.409、0.259和0.264,P<0.01),偏相关分析控制年龄、性别等混杂因素后,BMI和WHt R仍然与SBP、DBP相关(r值分别为0.251、0.271、0.217和0.180,P<0.01)。多因素logistic分析显示,高血压的危险因素为年龄(OR=1.068,95%CI:1.064~1.071)、吸烟(OR=1.163,95%CI:1.010~1.339)、饮酒(OR=1.343,95%CI:1.151~1.567)、农村居住(OR=1.178,95%CI:1.069~1.298)、高血压家族史(OR=1.371,95%CI:1.190~1.581)、超重(OR=1.847,95%CI:1.650~2.067)、肥胖(OR=3.379,95%CI:2.927~3.901)和WHt R≥0.5(OR=1.853,95%CI:1.648~2.084)。结论天津市城乡居民超重或肥胖率处于较高水平,并且在肥胖人群中有着较高的高血压患病率,控制体重对高血压等慢性病的防治具有重要意义。 Objective To understand the prevalence of overweight and obesity in urban and rural residents and their relationship with blood pressure in Tianjin and to provide a scientific basis for the prevention and control of overweight and obesity. Methods A multi-stage stratified random sampling method was used to select 12 600 permanent residents aged 15 years or older in 3 urban areas and 3 suburbs of Tianjin as survey subjects. The questionnaire and physical examination were conducted on the site, including demographic characteristics, life style and Disease history and other information, and measured height, waist circumference, weight and blood pressure, body mass index (BMI) and waist circumference ratio (WHtR). SPSS 20.0 statistical software t test, analysis of variance, χ ~ 2 test, correlation analysis and logistic regression analysis. Results A total of 12 474 participants (99.9% of the survey population), 3 980 (31.9%) were overweight, 1 770 (14.2%) were obese, 6 899 (55.3%) were WHt R ≥ 0.5, Obesity, central obesity indicators in gender, age, urban and rural differences were statistically significant (P <0.01); overweight or obesity, central obesity patients mean blood pressure and hypertension prevalence were higher than normal weight, the difference (P <0.01). Correlation analysis showed that BMI and WHt R were positively correlated with SBP and DBP (r = 0.300,0.409,0.259 and 0.264, P <0.01). BMI and WHt R were still related to SBP and DBP (r = 0.251,0.271,0.217 and 0.180, respectively, P <0.01) after partial correlation analysis controlled the confounding factors such as age and gender. Multivariate logistic analysis showed that the risk factors of hypertension were age (OR = 1.068, 95% CI: 1.064-1.071), smoking (OR = 1.163, 95% CI: 1.010-1.393) (OR = 1.178, 95% CI: 1.069-1.298), family history of hypertension (OR = 1.371, 95% CI: 1.190-1.581), and overweight : 1.650 ~ 2.067), obesity (OR = 3.379,95% CI: 2.927 ~ 3.901) and WHt R≥0.5 (OR = 1.853, 95% CI: 1.648 ~ 2.084). Conclusion The prevalence of overweight or obesity in urban and rural residents in Tianjin is at a high level and there is a high prevalence of hypertension among obese people. Weight control is of great importance for the prevention and treatment of chronic diseases such as hypertension.
