Abstract: Objective To study the correlation of serum chemerin, leptin and adiponectin levels with simple obesity and metabolism in preschool children aged 3 to 6 years, so as to provide basis for clinical monitoring and treatment efficacy evaluation of preschool simple obese children. Methods Children aged 3 to 6 years who underwent physical examination in Child Health Clinic of Dalian Maternal and Child Health Hospital from January 2019 to May 2020 were selected as study subjects. Forty one simple obese children were enrolled in the study group, and meanwhile another 43 children with the same age were selected as the control group. Their height and weight were measured, and calculate the height for weight was calculated. Serum levels of chemerin, leptin, adiponectin, fasting plasma glucose (FPG), fasting insulin (FINS), total triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c) were tested, and insulin resistance index was calculated. Results The levels of FINS, HOMA-IR, LDL-c, serum chemerin and leptin in the simple obesity group were significantly higher than those in the control group (t=3.288, 2.927, 4.939, 3.078, 5.456, P＜0.05),while the levels of HDL-c and adiponectin were significantly lower than those in the control group (t=-5.179, -3.145, P＜0.05). But there were no significant differences in the levels of FPG, TG and TC between the two groups (t=0.391, 0.768,-0.266, P＞0.05). Serum chemerin was positively correlated with height for weight and the levels of FINS, HOMA-IR, TG, LDL-c and leptin (r=0.339, 0.416, 0.227, 0.376, 0.266, P＜0.05), and negatively correlated with HDL-c and adiponectin levels (r=-0.410, -0.309, P＜0.05). Leptin level was positively related to height for weight, FINS, HOMA-IR, LDL-C and chemokine levels (r=0.492, 0.375, 0.279, 0.269, 0.266, P＜0.05), and negatively related to HDL-C and adiponectin (r=-0.467,-0.326,P＜0.05). The level of adiponectin was negatively correlated with height for weight, FINS, HOMA-IR, LDL-c, chemerin and leptin (r=-0.296, -0.351, -0.278, -0.229, -0.309, -0.326, P＜0.05), and positively correlated with HDL-c level(r=0.234, P=0.032). Conclusions The levels of serum chemerin, leptin and adiponectin are closely related to glucose and lipid metabolism in preschool simple obese children, which are of great significance for the identification, monitoring and intervention of preschool children with simple obesity.

摘要： 目的 研究血清趋化素、瘦素、脂联素水平与3~6岁学龄前期儿童单纯性肥胖及代谢的关系,为学龄前单纯性肥胖儿童临床监测及治疗效果提供依据。方法 选取2019年1月—2020年5月于大连市妇幼保健院儿童保健门诊体检的3~6岁儿童为研究对象,获取单纯性肥胖儿童41例作为研究组,另获取同年龄、同时期儿童43例作为对照组。测量其身高和体重,并计算身高别体重;测定血清趋化素、瘦素、脂联素、空腹血糖(FPG)、空腹胰岛素(FINS)、甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-c)、低密度脂蛋白胆固醇(LDL-c),同时计算胰岛素抵抗指数。结果 单纯性肥胖组的FINS、胰岛素抵抗指数(HOMA-IR),LDL-c,血清趋化素,瘦素明显高于对照组,差异有统计学意义(t=3.288、2.927、4.939、3.078、5.456,P＜0.05),HDL-c,脂联素明显低于对照组,差异有统计学意义(t=-5.179、-3.145,P＜0.05)。而两组FPG、TG、TC差异无统计学意义(t=0.391、0.768、-0.266,P＞0.05); 趋化素与身高别体重、FINS、HOMA-IR、 LDL-c、瘦素呈正相关(r=0.339、0.416、0.227、0.376、0.266,P＜0.05),与HDL-c、脂联素呈负相关(r=-0.410、-0.309,P＜0.05)。瘦素与身高别体重、FINS、HOMA-IR、 LDL-c、趋化素呈正相关(r=0.492、0.375、0.279、0.269、0.266,P＜0.05),与HDL-c、脂联素呈负相关(r=-0.467、-0.326,P＜0.05)。脂联素与身高别体重、FINS、HOMA-IR,LDL-c、趋化素、瘦素呈负相关(r=-0.296、-0.351、-0.278、-0.229、-0.309、-0.326,P＜0.05),与HDL-c呈正相关(r=0.234,P=0.032)。结论 血清趋化素、瘦素、脂联素水平与学龄前单纯性肥胖儿童糖脂代谢密切相关,这些指标对于识别、监测、干预学龄前单纯性肥胖儿童有着重要意义。
