Study type: Medical/biological study (experimental study)

Fetal and neonatal responses following maternal exposure to mobile phones. med./bio.

Published in: Saudi Med J 2008; 29 (2): 218-223

Aim of study (acc. to author)

To study fetal and neonatal heart rate and cardiac output, following acute maternal exposure to electromagnetic fields emitted by mobile phones.

Background/further details

90 women with uncomplicated pregnancies (18-33 years), and 30 healthy neonatal infants were investigated. They were classified into four groups: 1) 30 pregnant women (fetuses) with gestational age from 25-30 weeks, 2) 30 pregnant women with gestational age from 31-35 weeks, 3) 30 pregnant women with gestational age from 36-40 weeks, and 4) 30 neonatal babies. Neonates were examined in the first 48 hours after delivery, while their mothers were carrying them in a semisitting position. The physiological recording was performed 10 min without the use of mobile phone and 10 min with it.

Main outcome of study (acc. to author)

A statistical significant increase in fetal and neonatal heart rate, and a statistical significant decrease in diastolic volume, systolic volume, stroke volume and cardiac output after prenatal and postnatal maternal use of mobile phone were noted. The effect of exposure to mobile phone on all measures became smaller as the gestational age increased.
The results showed that exposure to electromagnetic fields emitted from mobile phones leads to fetal tachycardia.
