Neurodevelopment for first 3 years following prenatal mobile phone use, RF radiation & lead exposure

Abstract

Overview

This study investigates the impact of prenatal exposure to mobile phone use, radiofrequency radiation (RFR), and lead on child neurodevelopment up till the age of 36 months.

Background

Various research has shown differing outcomes concerning mobile phone use during pregnancy and its effects on child neurodevelopment stages.

Objectives

To explore child neurodevelopment following prenatal exposure to mobile phones and RFR, relating to prenatal lead exposure.

Methods

• Data from 1198 mother-child pairs from a prospective cohort study was analyzed.
• Mobile phone use and RFR exposure levels were measured through questionnaires and a 24-hour personal exposure meter.
• Child neurodevelopment was evaluated at multiple stages (6, 12, 24, and 36 months) using the Korean version of the Bayley Scales of Infant Development-Revised.

Findings

• No significant associations were noted between prenatal RFR exposure and child neurodevelopment.
• However, children exposed to higher levels of maternal blood lead levels showed a risk of impaired psychomotor development index and mental development index, especially related to maternal mobile phone use duration and frequency.

Conclusion

While prenatal RFR exposure did not show a direct risk, a connection involving high maternal blood lead levels with increased mobile phone use could potentially impair child neurodevelopment.
