目的研究重庆市低出生体重儿的影响因素,为预防和降低全市低出生体重发生率提供理论依据。方法采用1∶1病例对照研究方法选取重庆市6所妇幼保健院住院分娩的326名低出生体重儿和同期住院分娩的326名正常新生儿作为研究对象,利用问卷进行调查,采用单因素和多因素条件Logistic回归分析所获资料。结果低出生体重儿的发生可能与母亲一般情况(孕前BMI、受教育程度、家庭平均月收入等)、孕期情况(单胎、产前检查、妊娠期高血压疾病等)、生活习惯(吸烟、饮酒、被动吸烟等)和膳食营养(服用多种维生素片、食用鱼禽肉类、食用海产植物类等)有关。多因素分析结果显示,家庭平均月收入、单胎、孕期增重和产前检查是低出生体重儿的主要保护因素,妊娠期贫血是影响低出生体重儿的主要危险因素。结论低出生体重儿的发生受多方面因素共同作用的影响,应采取综合措施降低低出生体重儿的发生率。
Objective To study the influencing factors of low birth weight infants in Chongqing and to provide a theoretical basis for preventing and reducing the incidence of low birth weight in Chongqing. Methods A 1: 1 case-control study was conducted to select 326 low birth weight infants hospitalized in 6 maternal and child health centers in Chongqing and 326 normal newborns hospitalized during the same period as subjects. The questionnaires were used for the investigation. Single factor and multi Factors Logistic regression analysis of the data obtained. Results The incidence of low birth weight infants may be related to the general condition of the mother (pre-pregnancy BMI, educational level, average monthly family income, etc.), pregnancy status (single birth, prenatal examination, gestational hypertension, etc.) Alcohol consumption, passive smoking, etc.) and dietary nutrition (taking a variety of vitamin tablets, eating fish and poultry meat, eating marine plants, etc.). Multivariate analysis showed that average monthly household income, single birth weight, pregnancy weight gain and prenatal care were the main protective factors of low birth weight infants. Pregnancy anemia was the main risk factor affecting low birth weight infants. Conclusion The incidence of low birth weight children is affected by the combination of many factors. Comprehensive measures should be taken to reduce the incidence of low birth weight infants.
