目的:探讨巨大儿与母亲孕前体质指数及孕期增重的相关性。方法:选取我院2011年元月~2015年12月我院收治的45例妊娠孕妇作为研究对象,依据世界卫生组织(WHO)关于肥胖的标准的规定,按照孕前体质指数(BMI)将45例孕妇分为A、B、C三组,A组为孕前超重组,BMI≥25。B组为孕前正常体重组,18.5≤BMI≤25。C组为低体重组,BMI<18.5。以美国国家科学院医学科学院(IOM)的孕期增重推荐值(2009)为依据:肥胖孕妇5~9kg、超重孕妇7~11.5kg、低体重孕妇为12.5~18kg,将45例孕妇分为D、E、F三组。研究新生儿出生体重和孕妇孕前体质指数、孕期增重的相关性。结果:巨大儿出现4例,发生率8.8%。巨大儿发生率与孕前体质指数(BMI)、孕期增重呈正相关。新生儿出生体重最高的是A组,B组次之,C组最少。结论:巨大儿出生率与孕前BMI、孕期增重紧密相关,对围产期孕妇体重进行合理控制,做好孕期保健工作,有利于减少巨大儿的发生。
Objective: To investigate the correlation between the pre-pregnancy body mass index (MBI) and maternal weight gain during pregnancy. Methods: Forty-five pregnant women admitted to our hospital from January 2011 to December 2015 were selected as study subjects. According to the World Health Organization (WHO) standard on obesity, 45 pregnant women with pre-pregnancy body mass index (BMI) Pregnant women were divided into A, B, C three groups, A group of pre-pregnancy overweight group, BMI ≥ 25. Group B was normal weight before pregnancy group, 18.5≤BMI≤25. Group C was low body weight, BMI <18.5. Based on the recommendations of the United States National Academy of Academy of Medical Sciences (IOM) for pregnancy weight gain (2009): 5 to 9 kg of obese pregnant women, 7 to 11.5 kg of overweight pregnant women and 12.5 to 18 kg of pregnant women of low weight, 45 pregnant women are classified as D, E, F three groups. To study the relationship between newborn birth weight and pregnant women’s body mass index before pregnancy and weight gain during pregnancy. Results: 4 cases of giant children, the incidence rate of 8.8%. The incidence of macrosomia and pre-pregnancy body mass index (BMI), pregnancy weight gain was positively correlated. The highest birth weight of newborns is group A, followed by group B, and group C is the least. CONCLUSION: The birth rate of giant children is closely related to the BMI before pregnancy and the weight gain during pregnancy. It is reasonable to control the weight of pregnant women during perinatal period and do a good job in the health care during pregnancy, which is beneficial to reduce the incidence of huge children.
