目的分析孕前体型孕期锻炼与新生儿出生体重的关系,以探讨新生儿出生体重的影响因素。方法通过队列研究方法和纳入排除标准,对525例孕妇进行问卷调查和体格检查,以获得孕妇、新生儿的相关指标。结果河北省孕妇孕前体重不足为16.76%,超重率为13.9%,肥胖率为7.63%;孕期体重增加不足和过度发生率分别是8.8%,45.7%;孕期坚持锻炼对新生儿出生体重有显著的影响(F=3.82,P=0.034),孕期锻炼新生儿出生体重为(3.33±0.42)kg,而孕期没有坚持锻炼的新生儿出生体重为(3.36±0.44)kg。孕前体型对新生儿体重无显著影响(F=1.853,P>0.05)。结论河北省孕妇妊娠期体重增加过度现象较为严重;孕妇适当锻炼对新生儿成长有益,减少巨大儿的发生率。
Objective To analyze the relationship between pregnancy prenatal pregnancy weight and newborn birth weight in order to explore the influencing factors of newborn birth weight. Methods By means of cohort study and inclusion exclusion criteria, 525 pregnant women were investigated by questionnaires and physical examination to get the relevant indexes of pregnant women and newborns. Results The pregnant women in Hebei province had a weight less than 16.76%, an overweight rate of 13.9%, and an obesity rate of 7.63%. The underweight and overweight rates during pregnancy were 8.8% and 45.7% respectively. During pregnancy, exercise had significant effects on newborns’ birth weight (F = 3.82, P = 0.034). The birth weight of newborns during pregnancy training was (3.33 ± 0.42) kg, while that of infants born without exercise during pregnancy was (3.36 ± 0.44) kg. Pre-pregnancy size had no significant effect on newborn weight (F = 1.853, P> 0.05). Conclusion Excessive weight gain during pregnancy in Hebei pregnant women is more serious. Proper exercise in pregnant women is beneficial to the growth of neonates and reduces the incidence of macrosomia in pregnant women.
