【摘要】：研究目的：本研究采用BIA法,通过采集不同人群的体脂率探索其性别年龄特征。以超重、肥胖与代谢危险因素的密切关系为依据探索制定体脂率评价超重、肥胖的方法,希望为制定标准提供参考。研究方法：选取20-59岁成年人作为研究对象。研究一1728人(男性830人,女性898人)测试体脂率,探索体脂率的性别年龄特征；研究二选取参加健康风险测试的793人(男性452人,女性341人)作为研究对象。以危险因素聚集为标准,探索ROC曲线法建立体脂率评价超重、肥胖标准的可行性。研究结果：(1)随着年龄的增加,男性和女性的体脂率不断增加,但具有一定的年龄特征。男性可分为20-29岁和30-59岁两组：女性可分为20-49岁和50-59岁两组；(2)体脂率与SBP、DBP、FBG、TG、TC呈正相关关系,与HDL-C呈负相关关系；随着危险因素个数的增加,体脂率也呈不断增加的趋势,超过两个危险因素组(含两个)的体脂率与无危险因素组和1项危险因素组的体脂率具有统计学差异,因此危险因素聚集定义为两个及两个以上的危险因素存在；(3)对于20-29岁和30-59岁年龄组男性,当体脂率分别达到26.3%和21.2%时,灵敏度和特异度较好,且ROC曲线距离最小；当体脂率分别超过29.5%和30.1%时,特异度达到了90%；对于20-49岁和50-59岁年龄组女性,当体脂率分别达到28.7%、30.7%时,此时ROC曲线距离最小,而且灵敏度和特异度相对较好,当体脂率增加到33.5%和36.1%时,特异度超过90%。研究结论：(1)结合肥胖相关危险因素聚集特征,借助ROC曲线法制定体脂率评价成年人超重、肥胖标准是可行的；(2)体脂率筛查成年人超重、肥胖的适宜切点为：男性20-29岁和30-59岁超重切点为26.3%和21.2%,肥胖切点为29.5%和30.1%；女性20-49岁和50-59岁超重切点为28.7%和30.7%,肥胖切点为33.5%和36.1%;(3)对于30-59岁男性和女性,如果将体脂率分别控制在21.2%、28.7%和30.7%以下,可能防止61.5%、50%和61.1%的危险因素聚集；对体脂率在30.1%、33.5%和36.1%及以上者使用药物控制到切点以下,可能防止14.6%、18.2%和30.6%的危险因素聚集。
[Abstract]:Objective: to study the sex and age characteristics of body fat rate of different population by BIA method, and to establish a method to evaluate overweight and obesity based on the close relationship between overweight, obesity and metabolic risk factors. The aim of this study was to provide a reference for the establishment of standards. Methods: adults aged 20-59 were selected as subjects. Study 1 728 (830 males and 898 females) tested body fat rate to explore gender and age characteristics of body fat rate; In the second study, 793 people (452 males and 341 females) who participated in the health risk test were selected as the study subjects. Based on the risk factor aggregation criteria, the ROC curve was used to establish the body fat rate to evaluate overweight. The Feasibility of the Obesity Standard. The study found that the body fat rate of both men and women increases with age. But it has certain age characteristics. Men can be divided into two groups: 20-29 years old and 30-59 years old. Women can be divided into 20-49 years and 50-59 years old groups.) the body fat rate is positively correlated with SBP DBP, and negatively correlated with HDL-C, and with the increase of the number of risk factors, there is a positive correlation between body fat rate and HDL-C. The body fat rate of more than two risk factors (including two) was significantly different from that of non-risk factor group and one risk factor group. Therefore, risk factor aggregation is defined as the existence of two or more risk factors. For males aged 20-29 and 30-59, the sensitivity and specificity are better when body fat rates reach 26.3% and 21.2, respectively, and the ROC curve distance is the smallest. For women aged 20-49 and 50-59, when the body fat rates were 28.7 and 30.7, respectively, the distance of the ROC curve was the smallest, and the sensitivity and specificity were relatively good. When the body fat rate increased to 33.5% and 36.1, the specificity exceeded 90. Conclusion: 1) combined with the aggregation characteristics of obesity related risk factors, the body fat rate was determined by ROC curve to evaluate overweight in adults, and the obesity standard was feasible to screen overweight in adults. The suitable cutting points for obesity were 26.3% and 21.2 for men aged 20-29 and 30-59, 29.5% and 30.1for obesity, 28.7% and 30.7for women aged 20-49 and 50-59, 33.5% and 36.1for men and women aged 30-59, respectively. If the body fat rate was controlled below 21.2g% and below 30.7%, the aggregation of risk factors of 61.5% and 61.1% might be prevented, and those with body fat rate of 30.1% or 33.5% and 36.1% and above could be controlled below the cutting point, which might prevent the aggregation of risk factors of 14.6U 18.2% and 30.6%.
