A study was conducted in Iran to investigate a possible association between maternal exposure to electromagnetic field and speech problems in the offspring.
Remark EMF-Portal: It is not stated in the publication how speech problems of the children were defined and evaluated. Different exposure sources are listed in the abstract and the result section. The number of children with and without speech problems in the different exposure groups is not given. Due to the missing data it is not possible to retrace the results of the study.
The authors found a significant association between either the call time or history of maternal mobile phone use (months used) and speech problems in the offspring. Other exposures had no effect on the occurrence of speech problems.
The authors conclude that despite the relatively small sample size this study indicates that the maternal exposure to mobile phones can affect the occurrence of speech problems in the offspring.
