Prenatal and Postnatal Cell Phone Exposures and Headaches in Children.
This cohort analysis from the Danish National Birth Cohort examined whether prenatal and/or postnatal cell phone exposure was associated with headaches in children at age seven. Using maternal questionnaire data for 52,680 children, the study reports higher odds of migraines and headache-related symptoms among exposed children compared with unexposed children. The authors caution that the observed associations may not be causal due to possible uncontrolled confounding and exposure misclassification.
Key points
- The study used data from the Danish National Birth Cohort with child outcomes assessed at age seven years.
- Exposure was categorized as prenatal only, postnatal only, or both prenatal and postnatal cell phone exposure based on maternal questionnaire.
- Outcomes included migraines and headache-related symptoms reported in the questionnaire.
- Children with cell phone exposure had higher odds of migraines and headache-related symptoms than children with no exposure.
- For both prenatal and postnatal exposure, the reported odds ratio was 1.30 for migraines and 1.32 for headache-related symptoms.
- The authors state the associations may not be causal because of potential uncontrolled confounding and misclassification.
