Abstract

Objective

A meta-analysis of case-control studies was conducted to assess the risk of birth defects in offspring in China associated with maternal active and passive smoking and paternal smoking.

Methods

Four electronic databases were searched for qualified research up to December 2023. A Random-effect model or fixed-effect model was used to calculate the overall comprehensive risk estimates; and the relationship between parental smoking and the risk of birth defects in different periods of pregnancy. Subgroup and sensitivity analyses were performed to explore possible sources of heterogeneity.

Results

Sixty-two qualified studies involving 137,574 cases and 8,770,837 controls were included. Overall, maternal active smoking (OR = 2.19; 95% confidence interval (CI): 1.72–2.79; p < 0.01) and passive smoking (OR = 2.59,95% CI: 2.24–2.99; p < 0.01) as well as paternal active smoking (OR = 1.47,95% CI: 1.34–1.62; p < 0.01) were significantly associated with birth defect risk. The sources of heterogeneity were explored by subgroup analysis. Subgroup analysis showed that the risk of congenital heart disease in offspring was increased in paternal and maternal active smoking (OR = 2.97, 95% CI: 2.01–4.39; OR = 1.51, 95% CI: 1.30–1.74), respectively. Sensitivity analysis yielded consistent results.

Conclusion

Maternal active and passive smoking and paternal active smoking are risk factors for birth defects in offspring. Parents should be encouraged to quit smoking during the perinatal period and pregnancy.

期刊介绍： The journal Birth Defects Research publishes original research and reviews in areas related to the etiology of adverse developmental and reproductive outcome. In particular the journal is devoted to the publication of original scientific research that contributes to the understanding of the biology of embryonic development and the prenatal causative factors and mechanisms leading to adverse pregnancy outcomes, namely structural and functional birth defects, pregnancy loss, postnatal functional defects in the human population, and to the identification of prenatal factors and biological mechanisms that reduce these risks. Adverse reproductive and developmental outcomes may have genetic, environmental, nutritional or epigenetic causes. Accordingly, the journal Birth Defects Research takes an integrated, multidisciplinary approach in its organization and publication strategy. The journal Birth Defects Research contains separate sections for clinical and molecular teratology, developmental and reproductive toxicology, and reviews in developmental biology to acknowledge and accommodate the integrative nature of research in this field. Each section has a dedicated editor who is a leader in his/her field and who has full editorial authority in his/her area.
