We studied the relationship between different anthropometric indexes and plasma lipids. Data were collected from 2014 to 2016 in 854 schoolchildren (6-18 years). Waist circumference (WC), body fat percentage (BFP) by bioimpedance, body mass index (BMI), and waist-to-height ratio (WHtR) were measured. Total cholesterol (TC), HDLc, and triglycerides were measured in fasting blood samples and Non-HDL cholesterol (Non-HDLc) was calculated. Data are presented as mean ± standard deviation, with percentages. Means were compared using the t test or ANOVA followed by Tukey's test. The association between variables was tested by linear regression. The study was approved by the Research Ethics Committee of the Universidade Federal do Espírito Santo. Obese boys had higher TC, non-HDLc, and LDLc than eutrophic boys (p < 0.05). In girls this difference was found only for non-HDLc (p < 0.05). Children with inappropriate BFP and WHtR presented higher LDLc and non-HDLc concentrations (p < 0.001), which showed positive association (p<0.001) with lipid fractions (TC and non-HDLc). Excess body fat increased the probability of cholesterol above the reference value (170 mg/dL) by 21%. Excess body fat was associated with an atherogenic lipid profile (higher non-HDLc), especially in boys.
我们研究了不同人体测量指标与血脂之间的关系。2014年至2016年期间收集了854名6至18岁学童的数据。测量了腰围（WC）、通过生物电阻抗法测得的体脂百分比（BFP）、体重指数（BMI）和腰高比（WHtR）。在空腹血样中测量了总胆固醇（TC）、高密度脂蛋白胆固醇（HDLc）和甘油三酯，并计算了非高密度脂蛋白胆固醇（Non-HDLc）。数据以平均值±标准差及百分比形式呈现。采用t检验或方差分析（ANOVA）及后续的Tukey检验比较均值。通过线性回归检验变量之间的关联。本研究获得了圣埃斯皮里图联邦大学研究伦理委员会的批准。肥胖男孩的TC、非HDLc和低密度脂蛋白胆固醇（LDLc）高于营养正常的男孩（p<0.05）。在女孩中，仅在非HDLc方面发现了这种差异（p<0.05）。体脂百分比和腰高比不合适的儿童呈现出更高的LDLc和非HDLc浓度（p<0.001），这与血脂成分（TC和非HDLc）呈正相关（p<0.001）。体脂过多使胆固醇高于参考值（170mg/dL）的概率增加了21%。体脂过多与致动脉粥样硬化血脂谱（较高的非HDLc）相关，尤其是在男孩中。
