梧州市围产相关因素对生育LBWI的影响

Effects of perinatal related factors on fertility LBWI in Wuzhou

目的探讨低出生体重儿(LBWI)发生的围产相关因素。方法选择2019年1月至2021年7月在该院住院分娩活产的产妇分为两组:LBWI组为活产且生育新生儿出生体重<2500 g的产妇100例,对照组为随机选取的同期活产生育正常出生体重儿(体重2500~<4000 g)的产妇100例。分别调查两组产妇围产期情况并查阅围产保健手册记录,收集产妇一般情况、生活习惯及环境、产检和分娩情况等信息,进行单因素及多因素logistic回归分析。结果单因素分析结果显示,产妇是否为固定人口、文化程度、有无职业、运动时间是否大于1 h/d、喝咖啡或茶类的频率、孕期营养补充剂服用情况、餐次、家庭关系、工作或生活精神压力、不良接触史、双胎或多胎妊娠、是否妊娠高血压、孕期体重增长情况、是否早产、脐带扭转时间、胎盘重量对LBWI出生率均有明显影响(P<0.05);多因素logistic回归分析结果显示,被调查产妇为流动人口、工作或生活精神压力非常大、孕期未服用营养补充剂、孕期体重增长<11.5 kg、妊娠高血压、早产是影响LBWI出生率的主要因素(P<0.05)。结论影响LBWI发生的因素较多,围产期应提供高质量的孕产保健预防LBWI的发生。

Objective To investigate the perinatal related factors associated with low birth weight infants(LBWI).Methods From January 2019 to July 2021,a total of 200 puerperaes in this hospital were enrolled and divided into the low birth weight group(n=100),in which live birth and birth wight<2500 g,and the normal birth weight group(n=100),in which live birth and birth wight 2500—<4000 g.The perinatal conditions and the records of the perinatal care manual were investigated and consulted separately to collect general conditions,life habits,ambient environment,examinations during pregnancy and maternal delivery,etc.Univariate and multivariate logistic regression analysis were used to analyze the factors associated with LBWI.Results The results of univariate factor analysis showed that migrant pregnant women,education level,occupation or not,whether the exercise time was more than 1 h/d,the frequency of drinking coffee or tea,taking nutritional supplements during pregnancy,meal times,family relations,job or life mental stress,bad environmental exposure,twin or multifetal pregnancy,gestational hypertension or not,weight gain during pregnancy,premature delivery or not,umbilical cord twist and placenta weight were the main factors on the LBWI rates(P<0.05).The results of multivariate logistic regression analysis showed that migrant pregnant women,job or mental stress oversized,not taking nutritional supplements during pregnancy,weight gain during pregnancy<11.5 kg,pregnancy hypertension,and premature delivery were the main factors affecting the LBWI birth rate(P<0.05).Conclusion There are many factors affecting the occurrence of LBWI.High-quality maternal health care during the perinatal period should be provided to reduce the incidence of LBWI.
