RESUMEN
SUBJECT-MATTER: To assess the effect of the 2019 coronavirus (COVID-19) pandemic on gestational diabetes (GDM). MATERIAL AND METHODS: In this retrospective, multicentre, non-interventional study carried out in Castilla-La Mancha, Spain, we compared 663 women with GDM exposed to the pandemic (pandemic group), with 622 women with GDM seen one year earlier (pre-pandemic group). The primary endpoint was a Large for Gestational Age (LGA) newborn as an indicator of poor GDM control. Secondary endpoints included obstetric and neonatal complications. RESULTS: During the pandemic, the gestational week at diagnosis (24.2⯱â¯7.4 vs 22.9⯱â¯7.7, pâ¯=â¯0.0016) and first visit to Endocrinology (26.6⯱â¯7.2 vs 25.3⯱â¯7.6, pâ¯=â¯0.0014) were earlier. Face-to-face consultations were maintained in most cases (80.3%). The new diagnostic criteria for GDM were used in only 3% of cases. However, in the pandemic group, the final HbA1c was higher (5.2⯱â¯0.48 vs 5.29⯱â¯0.44%, pâ¯=â¯0.047) and there were more LGA newborns (8.5% vs 12.8%, pâ¯=â¯0.015). There were no differences in perinatal complications. CONCLUSIONS: Care for GDM in our Public Health System did not significantly deteriorate during the COVID-19 pandemic. However, this did not prevent a higher number of LGA newborns.
