The aim of this study was to determine the pregnancy outcomes in pregnant women with a history of previous gestational diabetes and its related recurrence risk factors. This study was conducted on 180 pregnant women with history of gestational diabetes in previous pregnancy that referred to Besat hospital, Sanandaj, Iran. They were divided into two groups (recurrence of gestational diabetes group and non-recurrence of gestational diabetes group) .The data were recorded in the check list and analyzed using SPSS software Ver.18. To analyze quantitative variables such as mother`s age, mother`s BMI, interval between pregnancies, Apgar score and neonatal hypoglycemia independent t-tests was used and to compare qualitative variables between the two groups chi square test was used. The results showed that there was no statistically significant difference between the two groups in terms of mother`s age (P = 0.22). In terms of mother’s BMI and interval between pregnancies there was statistically significant difference between the two groups (p<0.05). In terms of mode of delivery, after excluding 61 mothers who were replicate Cesarean section the percentage of Caesarean section in recurrence of gestational diabetes group was 15.4%4 and in non- recurrence of gestational diabetes group it was2.4% which difference was statistically significant (P <0.05). In terms of incidence of macrosomia (P <0.001) and neonatal hypoglycemia (p <0.05) there were statistically significant differences between two groups. The recurrence rate of diabetes was 66.6%.Regarding the results of this study in order to prevent maternal and fetal complications, monitoring and giving extra care to mothers with diabetes is recommended.
