目的 探讨脐血瘦素与新生儿出生体重、体脂指数以及与孕母体重、体脂指数的关系。方法 采用放射免疫法测定 4 2例新生儿 (男 2 4例 ,女 18例 )脐血瘦素的浓度 ,同时测量新生儿出生体重、身长以及孕母临近分娩时的体重及身高等 ,进行统计学分析。结果 (1)新生儿脐血瘦素水平 (6 0 6± 3 33) μg/L与出生体重、体脂指数呈正相关 (相关系数r分别为 0 5 0 ,0 5 4,P <0 0 1) ;(2 )LGA、AGA与SGA组间脐血瘦素水平有显著差异 (P <0 0 5 ) ;(3)新生儿脐血瘦素水平与孕母体重 (75 36± 8 5 8)kg及体脂指数 (2 8 4 1± 3 11)kg/m2无显著性相关。结论 脐血瘦素可作为评价胎儿宫内发育的一项营养指标
Objective To investigate the relationship between cord blood leptin and newborn birth weight, body fat index and body weight and body fat index. Methods Radioimmunoassay was used to determine cord blood leptin levels in 42 neonates (24 males and 18 females), and the newborn’s birth weight, length, body weight and height at the time of delivery were measured Analysis. Results (1) The level of cord blood leptin in newborns (6 0 6 ± 3 33) μg / L was positively correlated with birth weight and body fat index (correlation coefficient r was 0 50, 0 54, P 0 01, respectively ); (2) there was a significant difference in cord blood leptin levels between LGA, AGA and SGA groups (P <0.05); (3) cord blood leptin levels in neonates were significantly higher than those in pregnant males (75 36 ± 85 58) kg and body fat index (2 8 4 1 ± 3 11) kg / m2 were not significantly correlated. Conclusion Cord blood leptin can be used as a nutritional indicator of intrauterine growth
