摘要
目的探讨足月小样儿发生的影响因素,为预防足月小样儿提供依据。方法采用统一编制的调查问卷收集产妇及其新生儿的相关信息,对可能的影响因素进行单因素和多因素条件Logistic回归分析。结果多因素条件Logistic回归分析结果显示孕期增补叶酸、8次及以上产前检查、妊娠期贫血是足月小样儿的保护因素,其OR值分别为0.37、0.39和0.30;孕前体重过低[体重指数(BMI)<18.5 kg/m2]是足月小样儿的危险因素,其OR值为3.77。结论足月小样儿的发生与多个因素有关,需要采取综合措施来减少足月小样儿的发生。
Objective To explore the influence factors for small for gestational age（SGA） infant, that may provide the basis for intervention. Methods A case-control study of 104 cases SGA and 104 controls were performed by collecting all related data. The pos- sible influence factors of SGA were analyzed by using single- and multiple factors conditional Logistic regression model. Results Folie acid supplement during pregnancy,8 or more times of antenatal examination and anemia during pregnancy were shown to be protective factors for SGA. Their ORs were 0.37,0.39 and O. 30, respectively. Low pre-pregnancy weight （ BMI 〈 18.5 kg/m2 ） was risk factor of SGA and its OR was 3.77. Conclusions SGA was associated with many factors,we need to adopt comprehensive measures to reduce the occurrence of SGA.
