The known risk factors for Gestational Diabetes Mellitus (GDM) are advanced age (≥35 yrs.), overweight or obesity, excessive gestational weight gain, excessive central body fat deposition, family history of diabetes, short stature (<1.50 m), excessive fetal growth, polyhydramnios, hypertension or preeclampsia in the current pregnancy, history of recurrent miscarriage, offspring malformation, fetal or neonatal death, macrosomia, GDM during prior pregnancies and polycystic ovary syndrome. In addition to the most common factors the sedentary lifestyle may also be a risk factor for GDM.
To identify the presence of GDM risk factors during pregnancy at the time of diagnosis of this pathology.
Cross-sectional study of 76 pregnant women who were referred to a multidisciplinary clinic for high risk pregnancies, in a tertiary hospital in southern Brazil, at the time of GDM diagnosis. A trained interviewer administered a questionnaire to gather sociodemographic, clinical, anthropometric and lifestyle habits data. Pre-pregnancy nutritional status and weight gain were classified according to the Institute of Medicine guidelines. Current Body Mass Index (BMI) was classified by gestational week, according to Atalah. Because the risk of developing GDM gradually increases in overweight and obese women, the total sample was divided into three pre-pregnancy BMI groups for comparison: BMI <25 kg/m2, BMI ≥25 kg/m2 and <30 kg/m2 and BMI ≥30 kg/m2. Pearson Chi-square test, analysis of variance and Kruskal-Wallis were employed.
We observed a high prevalence of risk factors for GDM in this sample. An adequate pre-pregnancy nutritional status was associated with gestational weight gain above recommendations. These Results emphasize the need for pregnant women to be professionally monitored so that modifiable risk factors can be managed.
