【摘要】：研究目的:肥胖的流行,已成為一個公共的健康問題。腰圍已經被許多研究證實是反映人體腹部脂肪和健康風險因子的有效指標。但目前利用腰圍來診斷肥胖尚無統(tǒng)一的測量方法及診斷標準。本研究選取五處常用的腰圍測量點分別測量我國成年人的腰圍,比較不同測量部位的腰圍之間是否存在差異,分析不同部位的腰圍與腹部脂肪含量及全身脂肪含量的相關性,探討腰圍對心血管疾病風險因子的影響,從而找出最適合中國人的腰圍測量方法,為界定中國人肥胖的標準提供科學支持,使研究者和健康從業(yè)者能更有效的診斷肥胖,進而對其進行預防及治療。研究方法:本研究共招募213名18—35歲的中國成年人作為受試者,其中男性107名,女性106名。本研究選取了五個常用的腰圍測量點:(1)髂嵴的上緣(WC1);(2)第十二肋下緣(WC2);(3)髂嵴上緣與第十二肋下緣連線的中點(WC3);(4)肚臍上緣1 cm;(5)腰最細的部位。雙能X線骨密度儀用于測量受試者的全身脂肪質量,全身體脂率,腹部脂肪質量和腹部體脂率。心血管疾病風險因子包括空腹血糖(FBP)、甘油三酯(TG)、總膽固醇(TC)、高密度脂蛋白膽固醇(HDL-C)和低密度脂蛋白膽固醇(LDL-C)。所有數(shù)據均以平均數(shù)和標準差的方式表示,應用SPSS 20.0統(tǒng)計軟件進行統(tǒng)計學分析。重復性方差測量用于比較不同性別不同測量部位的腰圍之間是否存在差異;Pearson相關性分析用于確定腰圍與全身脂肪含量或腹部脂肪之間的相關性;二元邏輯回歸用于探討腰圍對心血管疾病風險因子的影響。統(tǒng)計學差異定為P0.05。研究結果:女性五個部位的腰圍均存在顯著性差異,表現(xiàn)為:WC5WC2WC3WC4WC1(P0.001)。男性除了WC5和WC2之間不存在顯著性差異外,其余部位的腰圍之間均存在顯著性的差異,表現(xiàn)為:WC5、WC2WC4WC3WC1(P0.001);男性五個部位的腰圍與全身脂肪質量(r=0.867~0.914,P0.001)和腹部脂肪質量(r=0.880~0.923,P0.001)之間呈極強相關,與全身體脂率(r=0.720~0.781,P0.001)和腹部體脂率(r=0.635~0.698,P0.001)之間呈強相關;女性五個部位的腰圍與全身脂肪質量(r=0.782~0.844,P0.001),腹部脂肪質量(r=0.678~0.740,P0.001)和腹部體脂率(r=0.627~0.671,P0.001)之間呈較強的相關性,和全身體脂率(r=0.570~0.633,P0.001)之間中等程度相關;男性WC3對心血管疾病危險因子的影響具有統(tǒng)計學意義,為危險因素。研究結論:中國成年人不同腰圍測量方法測量出的腰圍值不同,五個部位的腰圍是不可替換的。五個部位的腰圍與全身脂肪質量,全身體脂率,腹部脂肪質量和腹部體脂率都具有顯著的相關性。男性WC3為心血管疾病危險因子的危險因素。
[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.
