Abstract:Background: Rapid advances in technology, especially in the field of telecommunication, have led to extraordinary levels of mothers exposures to radiofrequency电磁场（RF-EMF）在怀孕之前或期间。
目标： is study was to answer this question whether exposure of women to common sources of RF-EMFs either prior to or during pregnancy is related to speech problems in the offspring.
Materials and Methods: In this study, mothers of 110 three-to-seven-year-old children with speech problems and 75 healthy children (control group) were interviewed.询问这些母亲是否接触过不同的EMF来源，例如手机，移动基站，Wi-Fi，无绳电话，笔记本电脑和电源线。 Chi square test was used to analyze the differences observed between the control and exposed groups.
Results: Statistically significant associations were found between the use of cordless phone and offspring speech problems for both before pregnancy and during pregnancy maternal exposures (P=0.005 and P=0.014, respectively).但是，由于手机率高在两组中使用E，这项研究都无法显示手机使用与后代语音问题之间的任何联系。此外，在怀孕前和怀孕期间再次生活在电力线附近和言语问题之间存在显着关联（分别为p = 0.003和p = 0.002）。但是，接触其他非电离辐射来源与语音问题无关。此外，暴露于电离辐射（例如，怀孕之前和期间的X射线照相）与语音问题的发生无关。
结论： ： > > ，尽管这项研究具有一定的限制，这使我们能够启用较高的限制，但它可以从较高的范围内进行启用。后代语音问题。
