This study was carried out in Mymensingh Medical College and Hospital, Mymensingh. The work, which lasted for one year commencing in July 2003, was designed to find out and compare the infant outcomes of gestational diabetes mellitus (GDM) with a view to reducing the complications. Forty cases of GDM with single pregnancy were selected as experimental group, while forty other cases of pregnant women without GDM constituted the control group. Questionnaire and observation charts were the research instruments. Statistical analyses were done manually. It was retrieved that the offspring of GDM mothers had a higher risk of macrosomia, neonatal jaundice and respiratory complications. The perinatal mortality rate was also more in GDM cases. However, befitting measures for prevention, treatment and management of GDM may be taken up to ameliorate the situation.
