title: Evaluation of factors affecting birth weight and preterm birth in southern Turkey.
abstract: OBJECTIVE
  To identify factors affecting birth weight and pre-term birth, and to find associations with electromagnetic devices such as television, computer and mobile phones.
  
  
  METHODS
  The study was conducted in Turkey at Gazintep University, Faculty of Medicine's Outpatient Clinic at the Paediatric Ward. It comprised 500 patients who presented at the clinic from May to December 2009. All participants were administered a questionnaire regarding their pregnancy history. SPSS 13 was used for statistical analysis.
  
  
  RESULTS
  In the study, 90 (19%) patients had pre-term birth, and 64 (12.9%) had low birth weight rate Birth weight was positively correlated with maternal age and baseline maternal weight (r = 0.115, p < 0.010; r = 0.168, p < 0.000, respectively). Pre-term birth and birth weight less than 2500g were more common in mothers with a history of disease during pregnancy (p < 0.046 and p < 0.008, respectively). The habit of watching television and using mobile phones and computer by mothers did not demonstrate any relationship with 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).
  
  
  CONCLUSIONS
  Mobile phones and computers may have an effect on pre-term birth.
