Abstract
OBJECTIVES
Multiple factors associated with neural tube defects (NTDs) risk have been identified, yet there is little evidence on the possible effects of maternal stressful life events. In this study, we aimed to investigate the association between stressful life events during the periconceptional period and risk of NTDs in offspring.
METHODS
Relevant literature was searched in PubMed, Springer Link, ScienceDirect, and Cochrane Library up to July 2023. The pooled odds ratio (OR) and 95% confidence interval (CI) of NTDs risk with maternal stressful life events were estimated using a random effects model. Publication bias was assessed using Egger's regression asymmetry test and Begg's rank correlation test with Begg's funnel plot.
RESULTS
Analysis results showed that mothers who experienced stressful life events during the periconceptional period were at greater risk of having NTDs offspring (OR: 1.37, 95% CI: 1.08-1.73) than those who did not. In subgroup analysis, the pooled OR was 1.37 (1.13-1.67) and 1.73 (0.36-8.32) for with and without adjusting for folic acid supplementation in each included study, while was 1.37 (1.13-1.67) and 1.64 (0.39-6.88) for exposure time of three months preconception until three months post conception and one year preconception until three months post conception, respectively.
CONCLUSIONS
This study suggests that maternal stressful life events during the periconceptional period are significantly associated with higher NTDs risk in offspring. Tailored approaches for evaluating the risk and policy of NTDs among women of childbearing age should emphasize individual stressful experiences before and during early pregnancy.
