Abstract：Objective To evaluate systematically the relationship between PM 2.5 exposure during pregnancy and low birth weight in ne-onates.Method All correlated studies of PM2.5 exposure during pregnancy in low birth weight in neonates published before January 2017 were searched in the Medline,Pubmed and Embase databases as well as the Chinese Biology Medicine and Wanfang data.The literatures were screened in accordance with the inclusion criteria,and the Meta analysis was conducted.Results Thirteen literatures were selected and the literature quality was high.Meta-analysis showed that PM2.5 exposure during pregnancy increased the risk of low birth weight in neonates (OR= 1.13,95％ CI:1.03～1.24).Both retrospective and prospective studies showed that PM 2.5 exposure increased the risk of low birth weight in neonates.Sensitivity analysis showed that the meta-analysis was relatively stable in assessing PM2.5 exposure to low birth weight in neo-nates.Conclusion Exposure to PM2.5 during pregnancy increases the risk of neonates with low birth weight. During pregnancy,pregnant woman should avoid PM2.5 exposure to improve pregnancy outcome.
