目的研究妊娠期轮班作业与低出生体重的关系。方法检索英文和中文数据库,按照预先制定的纳入排除标准筛选妊娠期轮班作业与低出生体重关系的文献(1977—2015年),提取纳入文献的数据,利用Stata 12.0的meta模块合并效应值,并对文献进行异质性分析。结果纳入8篇文献,妊娠期轮班作业与低出生体重关系的粗效应值合并为OR为1.15(95%CI:0.83~1.47),校正后的合并效应值OR为1.16(95%CI:0.79~1.53)。结论目前证据显示妊娠期轮班作业与新生儿低出生体重不相关,但还需要更高质量的研究证据。
Objective To study the relationship between job shift during pregnancy and low birth weight. METHODS: The databases of English and Chinese were searched. According to the pre-established literatures (1977-2015), screening out the relationship between shift jobs and low birth weight during pregnancy, the data were included in the literature, and the effect was merged using the meta-module of Stata 12.0. Heterogeneous analysis of the literature. Results The results of eight studies included the OR of 1.15 (95% CI: 0.83-1.47) for OR between shift job and low birth weight in pregnancy. The adjusted OR was 1.16 (95% CI: 0.79 ~ 1.53). CONCLUSIONS Current evidence shows that shift work during pregnancy is not associated with low birth weight in newborns, but more research evidence is needed.
