Conclusion (acc. to author)

90 (19%) mothers had pre-term birth and 64 (12.9%) had low birth weight. During the last pregnancy, all of the participants had watched TV every day, 343 (68%) of the mothers had used mobile phones and 99 (19.8%) of them had used computers. All the 3 devices were used by 99 (19.8%) mothers.
The habit of watching television and using mobile phones and computers by mothers did not show any relationship with the birth weight. Mothers who used mobile phones or computers during pregnancy had more deliveries before 37 weeks (p=0.018, p=0.034; respectively). Similarly, pregnancy duration was shorter in mothers who used either mobile phone or computers during pregnancy (p=0.005, p=0.048, respectively).
The authors concluded that mobile phone and computer use may have an effect on preterm birth.
