摘要
目的探讨广州市城市成年居民体质指数(BMI)、腰围(WC)对于预测和诊断高血压的实用价值和建议值,为确定肥胖和腹部肥胖的诊断指标及其界值提供科学依据。方法多阶段随机抽取广州市越秀区1 265名居民,进行问卷调查及身高、体质量、腰围和血压的测量。进行多元线性回归分析及logistic多因素分析。结果成年人体质指数、腰围分布存在明显的性别、年龄差异;平均收缩压和舒张压随着体质指数和腰围的增加而呈逐渐上升趋势,多元线形回归分析表明体质指数、腰围和血压值有明显的线形相关关系;控制年龄、性别、教育程度等混杂因素后,logistic回归分析显示发生高血压的危险性随着体质指数和腰围的增加而升高。结论建议以BMI为肥胖指标,BMI≥23诊断为超重、BMI≥29诊断为肥胖;以腰围为腹部肥胖指标,WC≥80为诊断界值。
Objective To assess the significance of body mass index (BMI) and waist circumference (WC) measurement in hypertension prediction and diagnosis and formulate the recommended values for these two indexes, aiming to provide scientific basis for determining the indicators and their cut-off points for obesity diagnosis in Chinese subjects. Methods A total of 1 265 residents over 20 years old were randomly selected from Yuexiu District of Guangzhou City in our multiphase study. Questionnaire-based survey was conducted in conjunction of the measurement of the height, body weight, WC and blood pressure, the results subjected to multivariate linear regression and logistic regression. Results The distribution of BMI varied significantly with gender and age with the subjects. The mean systolic and diastolic blood pressures both gradually increased with BMI, showing obvious linear relationship between BMI and blood pressure. After such factors as age, gender and education background etc were controlled, logistic regression analysis revealed that the risk for hypertension increased with BMI elevation. WC was related to the blood pressure in similar manner as BMI. Conclusions We suggest that BMI be used as the indexes for overweight and obesity, the diagnoses of which are established in cases with BMI≥23 and BMI≥29 respectively. As the diagnostic index for abdominal obesity, the cut-off point of WC≥80 cm should be instituted.
