【摘要】 目的探讨孕妇孕期增加体重与新生儿出生体重的关系。方法回顾分析669例产妇资料,均为初产、单胎妊娠,年龄25～34岁,孕前体重指数(BMI)为(18.5～23.9)kg/m2。将孕期增加体重分为三组:A组(体重增加≤9 kg,n=60)、B组[体重增加(9～18)kg,n=305]和C组(体重增加≥18 kg,n=45)。记录每例新生儿的出生体重,并进行相关性分析。结果 A组、B组和C组新生儿出生体重分别是(2993.43±348.70)g、(3161.68±464.56)g和(3330.82±415.81)g,差异有统计学意义。结论孕妇孕期增加体重与新生儿出生体重呈正相关。更多还原

【Abstract】 Objective: To discuss the correlation between gestational weight gain(GWG) and birth weight of newborn(NBW).Methods: 410 cases of primiparas giving birth to a single baby were recruited into the study,aged from 25 to 34 years and with the pre-pregnancy body mass index(BMI):(18.5~23.9)kg/m2.They were divided into three groups: Group A(≤9kg,n=60),Group B [(9~18)kg,n=305] and Group C(≥18kg,n=45) according to weight gain during pregnancy,and the NBW were obtained in each group.The relationship between GWG and NBW were analyzed.Results: The mean NBW of group A,B and C were(2993.43±348.70)g,(3161.68±464.56)g and(3330.82 ± 415.81)g respectively.There was significant difference in the NBW among three groups.Conclusion: There is a positive correlation between GWG and NBW.更多还原
