“While several studies reported no significant health threat, others suggested an association with adverse pregnancy outcomes. The most consistent evidence emerged for alterations in fetal and neonatal cardiac function and increased risk of preterm birth.”
“While agencies like the NIH and CDC note that benefits generally outweigh risks, the emerging evidence may support precautionary measures to reduce mobile phone usage during pregnancy, particularly among high-risk pregnant women.”
Members of the research team are with the medical and public health schools at Columbia University in New York City and Johns Hopkins University in Baltimore.

At about the same time, a second team —this one from India— published its own review of RF effects on pregnancy. They also looked at effects on children. Their findings are generally consistent with the American review.

It too calls for more researchre research: “Standardized, mechanistic, and long-term studies are needed to strengthen the scientific evidence base and inform public health policy.”
