Plain English Summary
Danish researchers followed over 13,000 children from pregnancy through age 7 to study whether mothers' cell phone use during pregnancy and children's own phone use affected behavior. They found that children exposed to cell phones both before birth and after had 80% higher odds of behavioral problems like hyperactivity and emotional difficulties. While the researchers noted other factors could explain this connection, the findings raise concerns given how widely cell phones are used.
Why This Matters
This landmark Danish study represents one of the largest investigations into prenatal EMF exposure and child development, with findings that deserve serious attention from parents and policymakers. The 80% increase in behavioral problems among children with both prenatal and postnatal cell phone exposure is substantial, particularly when you consider that typical cell phone use during pregnancy involves carrying phones close to the developing fetus for hours daily. While the researchers appropriately acknowledge that unmeasured confounding factors could explain these associations, the biological plausibility is supported by growing evidence that EMF exposure can affect neurodevelopment. What makes this study particularly compelling is its prospective design and large sample size, following children from conception through school age. The reality is that pregnant women today carry smartphones constantly, often keeping them in pockets or purses against their bodies, creating chronic low-level exposure to the developing brain during critical windows of development.

We examined the association between prenatal and postnatal exposure to cell phones and behavioral problems in young children.

Exposure to cell phones prenatally-and, to a lesser degree, postnatally-was associated with behavioral difficulties such as emotional and hyperactivity problems around the age of school entry. These associations may be noncausal and may be due to unmeasured confounding. If real, they would be of public health concern given the widespread use of this technology.
