目的探讨腰高比与青少年代谢综合征的相关性,为代谢综合征的预防提供理论依据。方法以全国9个城市城乡中学初一、初二、高一、高二学生和省属大学大一、大二学生作为目标人群,对其进行体格检查,并按照知情同意的原则,检测部分目标人群的空腹血糖和血脂。共获得有效人体测量和血压样本12 106份,获得有效空腹血样7 738份。以腰高比≥0.05作为高腰高比的划界标准,按照国际糖尿病联盟提出的儿童青少年代谢综合征诊断标准筛选代谢综合征;运用χ2检验和单因素Logistic回归分析方法分析腰高比与代谢综合征的相关性。结果青少年代谢综合征检出率为2.0%,高腰高比检出率为7.4%,性别差异均无统计学意义。高腰高比组代谢综合征检出率(14.7%)显著高于对照组(0.8%)(χ2=592.63,P<0.01),对照组和高腰高比组具有1个代谢综合征症状的比例分别为31.8%和43.8%,有2个代谢综合征症状的比例分别为7.4%和39.9%。高腰高比与代谢综合征之间关联的OR值为6.84(95%C I=4.366～11.889),与中心性肥胖、血压偏高、高三酰甘油和低高密度脂蛋白检出率的正相关均有统计学意义(P<0.05)。结论高腰高比与代谢综合征及其症状均有较好的相关性,并且能较好的反映体脂的中心性分布情况。
Objective To investigate the correlation between waist-height ratio and adolescent metabolic syndrome and to provide a theoretical basis for the prevention of metabolic syndrome. Methods Taking the freshmen, sophomores, sophomores and sophomores in 9 urban and rural secondary schools in China and the freshmen and sophomores of provincial universities as the target population, physical examination was carried out and the target groups were tested according to the principle of informed consent Fasting blood glucose and blood lipids. A total of 12 106 valid human body measurements and blood pressure samples were obtained, and 7 738 valid fasting blood samples were obtained. The waist-height ratio≥0.05 was used as the demarcation criterion of high waist-height ratio, and the metabolic syndrome was screened according to the diagnostic criteria of metabolic syndrome in children and adolescents proposed by the International Diabetes Federation. Chi-square test and single-factor Logistic regression analysis were used to analyze the relationship between waist height and metabolic syndrome Relevance. Results The detection rate of metabolic syndrome in adolescents was 2.0%, and the detection rate of high waist ratio was 7.4%. There was no significant difference in gender. The detection rate of metabolic syndrome in high waist ratio group (14.7%) was significantly higher than that in control group (0.8%) (χ2 = 592.63, P <0.01), and the control group and high waist ratio group had one metabolic syndrome The proportions were 31.8% and 43.8% respectively, with the proportion of 2 metabolic syndromes being 7.4% and 39.9% respectively. The correlation between high waist-height ratio and metabolic syndrome was 6.84 (95% CI = 4.366 ~ 11.889), which was positively correlated with the prevalence of central obesity, high blood pressure, high triglyceride and low-density lipoprotein There was statistical significance (P <0.05). Conclusion The high waist-to-waist ratio has a good correlation with metabolic syndrome and its symptoms, and can better reflect the central distribution of body fat.
