Association of serum apolipoprotein A5 with leptin and insulin in obese children / 中华内分泌代谢杂志

ABSTRACT

Totally 79 obese children and 64 children with normal body weight were included in the present study.Serum apolipoprotein A5 (ApoA5) and leptin levels were determined by ELISA and fasting insulin by RIA.The clinical data including height,body weight,waist circumference,blood pressure,blood lipid,blood glucose,etc,were collected.Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated.The results showed that compared with normal weight children,both serum leptin and insulin levels were significantly raised in obese children [19.15 (13.01 ～ 25.08) ng/ml vs 3.29 (1.45 ～ 6.02) ng/ml and 15.44 (12.05 ～ 20.26) μg/L vs 10.12 (8.60 ～ 12.60) μg/L,both P＜0.01],while ApoA5 level was significantly lowered [134.5 (105.9 ～ 172.7) ng/ml vs 2005.9(164.3 ～ 265.3) ng/ml,P＜0.01].Serum ApoA5 was negatively correlated with serum leptin and insulin (both P＜0.01).
