Risk of developing gestational diabetes in women after assisted reproductive technologies

Abstract

Hypothesis/aims of study. Gestational diabetes mellitus (GDM) is one of the leading causes of perinatal morbidity and mortality. The use of assisted reproductive technologies (ART) is an independent risk factor for the development of GDM. Among other risk factors are overweight, diabetes burdened heredity, previous GDM, previous birth weight more than 4 kgs, stillbirth, miscarriage in history, glucosuria, polyhydramnios in this pregnancy, age over 30 years, polycystic ovary syndrome. The most significant risk factor for GDM is excess weight before pregnancy. The aim of this study was to investigate the risks of GDM in patients after ART.
 Study design, materials, and methods. 342 case histories of women with single pregnancy for the period 2014–2017 were studied on archival material. The main group consisted of 234 women with single pregnancy after ART. The comparison group comprised 108 medical records of fertile women with a history of single pregnancy that occurred spontaneously. The exclusion criteria in the comparison group were pregestational diabetes mellitus and severe extragenital pathology.
 Results. The incidence of GDM was significantly higher in the group of women in whom pregnancy occurred after ART compared to the comparison group (15.4 ± 0.4% and 5.5 ± 0.4% respectively). In the main group, patients were more likely to have overweight, extragenital pathology and pregnancy complications.
 Conclusion. The increase in the frequency of GDM among patients after ART is probably associated with late reproductive age, initially negative somatic background at the time of entry into the IVF protocols, as well as long-term hormone therapy during pregnancies after ART, starting from early terms.
