摘要
目的探讨营养不良儿童血清瘦素水平的变化及与能量摄入的相关性。方法检测32例营养不良患儿的空腹血清瘦素水平、体重指数(BMI)、能量摄入量,与32例健康儿童比较,同时分析血清瘦素水平与BMI、能量摄入的相关性。结果观察组的血清瘦素1.35μg/ml,BMI为13.4kg/m2、能量摄入为3809kJ/d,明显低于对照组的4.20mg/ml、16.3kg/m2及5217kJ/d(均P<0.05)。但血清瘦素与能量摄入无显著的相关性(P>0.05)。结论营养不良儿童血清瘦素水平明显降低,其原因除了患儿脂肪含量下降致瘦素分泌减少外,还与能量摄入的减少有关。
Objective To analyze the correlation between serum leptin levels and caloric intake in children with malnutrition. Methods Fasting serum leptin concentrations, BMI and caloric intake were measured in 32 children with malnutrition (experimental group) and 32 healthy children (control group). Results (1) The serum leptin level, BMI and caloric intake in children with malnutrition were significantly lower than that of controls ( P <0.05). (2) There was no correlation between serum leptin levels and caloric intake ( P >0.05). Conclusions In children with malnutrition, serum leptin levels were low. It might due to the decreasing of calories intake and diminution of the fat mass in the body.[
