Obstetric and socio-demographic data were collected. Results: A higher therapeutic adherence was associated with a better glycemic control. Women with a higher education level had a better adherence to treatment. The adherence and metabolic control were higher in women treated with metformin. Conclusions: Therapeutic adherence is an important factor for adequate glycemic control.
