ABSTRACT

Introduction: Gynecologists and pediatrics traditionally recommend non-fasting state in the second and third trimesters since the neonate's growth in this period is rapid, but there is no obvious scientific data based on this rationale. This study was conducted to compare maternal and neonatal outcomes arising from fasting in three trimesters and also to compare it with non-fasting mothers and their neonates.
Methods: This cross-sectional study covered 1000 mothers who had delivered at Mashhad Ghaem Hospital between 2009 and 2013. Samples were divided into two groups of case and control based on fasting or non-fasting history during pregnancy. There were 614 and 386 in the case and control group respectively. The maternal [age, weight before pregnancy, pregnancy complications, urinary tract infection (UTI) and neonatal characteristics (birth height and weight, abnormality, Apgar score)] in each trimester of pregnancy were compared between the two groups.
Results: Significant differences were obtained between the cases and control groups for (i) UTI in the 1st and 2nd trimesters; (ii) number of preterm labour in the 1st and 3rd trimesters; (iii) Apgar score in the 1st and 5th minute during the 1st trimester.
Conclusion: Fasting appeared to exert no negative effects on maternal and neonatal outcomes except for UTT. Therefore, control of UTI during the prenatal period would be helpful.
