肥胖人群体脂分布特点及与心血管疾病危险因素相关性分析

Analyzing Body Fat Distribution Characteristics and Correlation with Cardiovascular Risk Factors of Obese People

目的探究肥胖人群的体脂分布特点并分析其体脂分布特点与心血管疾病危险因素之间的关系。方法选取2017年7月至2018年7月接受调查的618例肥胖人群志愿者,于其腰椎L4-L5间隙平面进行计算机扫描,采取横断面研究,测量其腹壁皮下脂肪面积(SA)与腹腔内脏器脂肪面积(VA)并计算二者的比值(VSR)。同时,给予志愿者血脂、血压、身高、体重以及BMI指数的检测,分析志愿者的体脂分布特点以及其与心血管疾病危险因素之间的相关性。结果内脏型肥胖者的甘油三酯、低密度脂蛋白高于腹壁皮下型肥胖者。给予偏相关分析,对年龄与BMI进行校正,可知所有志愿者的(VSR)均和甘油三酯、低密度脂蛋白呈正相关联系,(SA)与甘油三酯、低密度脂蛋白呈负相关联系。结论心血管危险因素不仅和总体脂增加有密切联系,与局部体脂的增加也有一定联系。

Objective To explore body fat distribution characteristics of obese people and analyze relationship with cardiovascular risk factors.Methods Choose 618 cases obese volunteers from July 2017 to July 2018 with L4-L5 interval plane scan of lumbar spine.Measure abdominal subcutaneous fat area and abdominal viscera fat area,calculate ratio of them based on cross-sectional study.At the same time,detect blood lipid,blood pressure,height,weight and BMI index of volunteers,and analyze distribution characteristics of body fat and correlation with cardiovascular disease risk factors.Results Levels of triglyceride and low density lipoprotein in visceral obesity were higher than abdominal subcutaneous obesity.Based on partial correlation analysis and BMI correction,VSR of volunteers was positively correlated with triglyceride and LDL,and SA was negatively correlated with triglyceride and LDL.Conclusion Cardiovascular risk factors are not only closely related to increase of total body fat,but to increase of local body fat.
