BMI与人体相关指标的关系研究

目的 研究体重指数BMI与人体相关指标（血液粘度、血糖、血脂及血压）的关系。方法对1950例体检者的资料进行统计分析，按BMI不同分为4组：低体重组（BMI：〈18．5），正常体重组（BMI：18．5～23．9），超重组（BMI：24．0～27．9），肥胖组（BMI：≥28）。结果随BMI逐渐升高，血压、血液粘度、TC、TG、LDL—C均呈上升趋势，而HDL—C呈下降趋势。同一研究指标，组间有显著性差异。结论体重指数BMI升高引起明显的脂质代谢紊乱，造成发生心血管疾病的危险性增加，定期体检有利于疾病的早期发现。

The study of the relationship between BMI and human-related indicatars

Objective To investigate the relationship between BMI and human-related in-dicators (blood glucose, the blood lipid, the blood viscosity and the blood pressure). Methods The study was carried out in 1950 cases, who participated in health examination in Dongshan Division, the First Affiliated Hospital, Sun Yat-sen University. According to Body Mass Index, the cases were divided into 4 group: the underweight group (BMI: <18.5), the normal group (BMI: 18.5 ～ 23.9); overweight group (BMI: 24 ～ 27.9), the obesity group (BMI: ≥ 28).Results With the increasing of BMI, the level of the viscosity of blood, blood pressure, total cholesterol(TC), triglycerides(TG) and low-density lipoprotein (LDL), blood glucose, showed a trend of linear increase, but High-density lipoprotein (H DL) showed a trend of linear decrease. According to the same indicators in the study, there were significant differences in the groups.Conclusions Following the body mass index increasing, abnormal metabolism of lipids existed in obese adult, the risks of cardiovascular diseases are increased, it is very important to participate in regular health examination.
