Because of the need to measure anthropometric, biochemical and hemodynamic variables for the diagnosis of metabolic syndrome, we realize how difficult it is to analyze large populations, especially children, due to the poor accessibility and the invasive character. There is an urgent need to develop easy-to-use, accurate and low-cost diagnostic tools in order to predict metabolic syndrome at early ages.
To verify the prevalence of metabolic syndrome in children and to test predictive anthropometric indicators.
Cross-sectional study conducted among 109 children aged 7 to 11 years. The age-adjusted National Cholesterol Education Program definition was used for the diagnosis of metabolic syndrome. The following parameters were tested as possible predictors: body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), conicity index (C index), and body fat percentage.
The prevalence of metabolic syndrome was 13.3% and 36% for boys and girls, respectively. The main anthropometric indicators were: BMI = 0.81 (0.69 - 0.94), WC = 0.79 (0.64 - 0.94), body fat = 0.79 (0.66 - 0.92) and WHR = 0.37 (0.21 - 0.54).
WC higher than 78 cm, body fat higher than 41%, and BMI higher than 24.5 kg/m² were considered predictors of metabolic syndrome. The C index and WHR were not considered predictors.
由于需要测量人体测量学、生化和血液动力学变量来诊断代谢综合征，我们意识到分析大量人群，尤其是儿童，是多么困难，因为这些人群的可及性较差且具有侵入性。因此，迫切需要开发易于使用、准确且低成本的诊断工具，以便在早期预测代谢综合征。
验证儿童代谢综合征的患病率，并检验预测性人体测量学指标。
在 109 名 7 至 11 岁的儿童中进行了横断面研究。采用经年龄校正的国家胆固醇教育计划定义来诊断代谢综合征。测试了以下可能的预测指标：体重指数（BMI）、腰围（WC）、腰臀比（WHR）、锥形指数（C 指数）和体脂百分比。
男孩和女孩的代谢综合征患病率分别为 13.3%和 36%。主要的人体测量学指标是：BMI = 0.81（0.69-0.94），WC = 0.79（0.64-0.94），体脂 = 0.79（0.66-0.92）和 WHR = 0.37（0.21-0.54）。
WC 高于 78cm、体脂高于 41%和 BMI 高于 24.5kg/m²被认为是代谢综合征的预测指标。C 指数和 WHR 不被认为是预测指标。
