【摘要】：研究目的:肥胖的流行,已成为一个公共的健康问题。腰围已经被许多研究证实是反映人体腹部脂肪和健康风险因子的有效指标。但目前利用腰围来诊断肥胖尚无统一的测量方法及诊断标准。本研究选取五处常用的腰围测量点分别测量我国成年人的腰围,比较不同测量部位的腰围之间是否存在差异,分析不同部位的腰围与腹部脂肪含量及全身脂肪含量的相关性,探讨腰围对心血管疾病风险因子的影响,从而找出最适合中国人的腰围测量方法,为界定中国人肥胖的标准提供科学支持,使研究者和健康从业者能更有效的诊断肥胖,进而对其进行预防及治疗。研究方法:本研究共招募213名18—35岁的中国成年人作为受试者,其中男性107名,女性106名。本研究选取了五个常用的腰围测量点:(1)髂嵴的上缘(WC1);(2)第十二肋下缘(WC2);(3)髂嵴上缘与第十二肋下缘连线的中点(WC3);(4)肚脐上缘1 cm;(5)腰最细的部位。双能X线骨密度仪用于测量受试者的全身脂肪质量,全身体脂率,腹部脂肪质量和腹部体脂率。心血管疾病风险因子包括空腹血糖(FBP)、甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)。所有数据均以平均数和标准差的方式表示,应用SPSS 20.0统计软件进行统计学分析。重复性方差测量用于比较不同性别不同测量部位的腰围之间是否存在差异;Pearson相关性分析用于确定腰围与全身脂肪含量或腹部脂肪之间的相关性;二元逻辑回归用于探讨腰围对心血管疾病风险因子的影响。统计学差异定为P0.05。研究结果:女性五个部位的腰围均存在显著性差异,表现为:WC5WC2WC3WC4WC1(P0.001)。男性除了WC5和WC2之间不存在显著性差异外,其余部位的腰围之间均存在显著性的差异,表现为:WC5、WC2WC4WC3WC1(P0.001);男性五个部位的腰围与全身脂肪质量(r=0.867~0.914,P0.001)和腹部脂肪质量(r=0.880~0.923,P0.001)之间呈极强相关,与全身体脂率(r=0.720~0.781,P0.001)和腹部体脂率(r=0.635~0.698,P0.001)之间呈强相关;女性五个部位的腰围与全身脂肪质量(r=0.782~0.844,P0.001),腹部脂肪质量(r=0.678~0.740,P0.001)和腹部体脂率(r=0.627~0.671,P0.001)之间呈较强的相关性,和全身体脂率(r=0.570~0.633,P0.001)之间中等程度相关;男性WC3对心血管疾病危险因子的影响具有统计学意义,为危险因素。研究结论:中国成年人不同腰围测量方法测量出的腰围值不同,五个部位的腰围是不可替换的。五个部位的腰围与全身脂肪质量,全身体脂率,腹部脂肪质量和腹部体脂率都具有显著的相关性。男性WC3为心血管疾病危险因子的危险因素。
[Abstract]:Objective: to investigate the prevalence of obesity. Waist circumference has been proved to be an effective indicator of abdominal fat and health risk factors. However, there is no uniform measurement method and diagnosis of obesity using waist circumference. Standard. This study selected five commonly used waist measurement points to measure the waist circumference of Chinese adults. To compare the differences of waist circumference between different measuring sites, to analyze the correlation between waist circumference and abdominal fat content and body fat content, and to explore the influence of waist circumference on cardiovascular disease risk factors. In order to find out the most suitable for the Chinese waistline measurement for the definition of Chinese obesity standards to provide scientific support so that researchers and health practitioners can more effectively diagnose obesity. Methods: a total of 213 Chinese adults aged 18-35 years were recruited as subjects, including 107 males. 106 women. In this study, we selected five commonly used waist circumference measurement points: 1) the upper margin of iliac crest, WC1; (2) WC2 (12th); (3) the midpoint of the line between the superior margin of iliac crest and the inferior margin of 12th ribs. The upper margin of navel was 1 cm; Double energy X-ray absorptiometry was used to measure the body fat mass and body fat rate of the subjects. Abdominal fat mass and abdominal body fat rate. Risk factors for cardiovascular disease included fasting blood glucose (FBPN), triglyceride (TGG), total cholesterol (TC). High density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C). All data were expressed as average and standard deviation. Statistical software SPSS 20.0 was used to analyze the difference of waist circumference between different sex and different parts of the body, and repeated variance measurement was used to compare whether there were differences in waist circumference. Pearson correlation analysis was used to determine the correlation between waist circumference and body fat content or abdominal fat. Binary logistic regression was used to study the influence of waist circumference on risk factors of cardiovascular disease. The statistical difference was P0.05.Results: there were significant differences in waist circumference of five parts of women. The results were as follows: WC5WC2WC3WC4WC1P 0.001. except for WC5 and WC2, there was no significant difference in waist circumference between male and male. WC5, WC2WC4WC3WC1, P0.001; The waist circumference and body fat weight of the five parts of the male were 0.914 P0.001) and the abdominal fat weight was 0.880 ~ 0.923. There was a strong correlation between P0.001 and total body fat rate (r = 0.720 / 0.781g / P 0.001) and abdominal body fat rate (r = 0.635 / 0. 698). P0.001); The waist circumference and body fat weight of the five parts of the female were 0.782U 0.844m P 0.001g, and the abdominal fat weight was 0.6780.7040. There was a strong correlation between P0.001) and abdominal body fat rate (0.671P 0.001), and there was a strong correlation with the whole body fat rate (r = 0.570 ~ 0.633). P0.001); The influence of male WC3 on cardiovascular disease risk factors is statistically significant. Conclusion: the waist circumference values measured by different waist circumference measurement methods in Chinese adults are different. The waist circumference of five parts is irreplaceable. The waist circumference of five parts is related to the mass of whole body fat and the ratio of body fat to body fat. There was a significant correlation between abdominal fat mass and abdominal body fat rate. Male WC3 was a risk factor for cardiovascular disease.
