Maternal infections and antibiotic prescriptions during pregnancy are associated with an increased risk of childhood cancer, especially acute lymphoblastic leukemia (ALL). Maternal use of certain antibiotics, particularly tetracyclines, is also associated with an elevated risk of childhood cancer. Further research is needed in this area.
While associations between maternal infections during pregnancy and childhood leukemia in offspring have been extensively studied, the evidence for other types of childhood cancers is limited. Additionally, antibiotic exposure during pregnancy could potentially increase the risk of childhood cancers. Our study investigates associations between maternal infections and antibiotic prescriptions during pregnancy and the risk of childhood cancer in Taiwan. We conducted a population-based cohort study using the Taiwan Maternal and Child Health Database (TMCHD), linked with national health and cancer registries. The study included 2 267 186 mother-child pairs, and the median follow-up time was 7.96 years. Cox proportional hazard models were utilized to estimate effects. Maternal infections during pregnancy were associated with a moderate increase in the risk of childhood hepatoblastoma (adjusted hazard ratio [HR] = 1.34; 95% confidence interval [CI]: 0.90-1.98) and a weaker increase in the risk of childhood acute lymphoblastic leukemia (ALL) (adjusted HR = 1.15; 95% CI: 0.99-1.35). Antibiotic prescriptions during pregnancy were also associated with an elevated risk of childhood ALL (adjusted HR = 1.30; 95% CI: 1.04-1.63), particularly with tetracyclines (adjusted HR = 2.15; 95% CI: 1.34-3.45). Several specific antibiotics were also associated with an increased risk of hepatoblastoma and medulloblastoma. Children exposed in utero to antibiotic prescription or both infections and antibiotics during pregnancy were at higher risk of developing ALL. Our findings suggest that there are associations between maternal infections, antibiotic use during pregnancy and the risk of several childhood cancers in addition to ALL and highlight the importance of further research in this area. Maternal infection and antibiotic exposure during pregnancy are potential risk factors for childhood cancer. Previous studies of possible associations between these factors and childhood cancer risk, however, have focused mainly on European and U.S. populations. Here, relationships between childhood cancer and medically diagnosed maternal infection and antibiotic use during pregnancy were explored in a Taiwanese population. Analyses reveal moderate associations between maternal infection during pregnancy and childhood hepatoblastoma risk and risk of childhood acute lymphoblastic leukemia (ALL). Maternal use of certain antibiotics during pregnancy increased childhood hepatoblastoma and ALL risk, with ALL risk especially linked to maternal tetracycline use.image
