摘要： 目的：探讨母亲孕前体质指数（Body mass index, BMI）、孕期体重增加量（Gestational weight gain, GWG）与新生儿发育指标的关系。方法：选取2014年9月至2015年1月于哈尔滨医科大学附属第二医院住院分娩的157例孕妇为研究对象。纳入标准：所有孕妇既往身体健康，无代谢性疾病家族遗传史，均为初产、单胎妊娠。收集孕妇孕前体重、产前体重，以及新生儿出生体重、身长、头围等数据。分析孕前BMI、GWG与新生儿出生体重、身长、头围的关系，及可能存在的交互作用。结果：孕前BMI和GWG对新生儿出生体重的主效应有统计学意义（P<0.01），未发现两者对新生儿生长发育存在交互作用。结论：控制孕前BMI和GWG可能是优化新生儿出生体重的有效途径。

Abstract： Objective: To explore the association of pre-pregnant body mass index (BMI) and gestational weight gain (GWG) with neonatal growth. Methods: The 157 eligible participants, who are healthy, do not have family history of metabolic diseases, were collected from the Second Affiliated Hospital of Harbin Medical University from September, 2014 to January, 2015. Maternal pre-pregnant and antenatal body weight and neonatal birth weight, body length, and head circumference were collected using questionnaire. Results: Maternal pre-pregnant BMI and GWG were significantly associated with neonatal birth weight, however, there was no significant interactive effect of pre-pregnant BMI and GWG on birth weight. Conclusion: Controlling maternal pre-pregnant BMI and GWG may represent an effective way to optimize neonatal birth weight.
Keywords： pre-pregnant body mass index; gestational weight gain; birth weight
