Obesity is becoming one of the most important health issues. In pregnancy, overweight mothers are at risk for hypertensive disorders, operative complications, thrombo-embolic disease, instrumental delivery and neonatal morbidity and mortality. Our goal was describe the evolution of bodyweight and weight gain during pregnancy over the past decade.
We analysed the electronic registers for preconceptional weight and weight at the time of delivery in all mothers who gave birth in the University Hospital of Leuven ( Belgium) from 1993 until 2002. We compared cohorts of consecutive deliveries from 1993 and 2003. We analysed body weight at delivery, preconceptional weight, maternal length, placental and neonatal weight and complications during pregnancy. The mean (±SD) values obtained of the two cohorts were compared using a student’s t-test.
We obtained data in 24411 pregnancies. Non-pregnant body weight increased by 2.8 (± 2.8) kg in ten years (p<0.05). Accordingly, weight gain during pregnancy was 1.4 kg (± 0.4) higher in 2002 compared to 1993 (p<0.05). We found no difference in length, weight of the baby and weight of the placenta.
Our study shows an important increase in body weight and weight gain during pregnancy that cannot be explained by an increase in maternal length, fetal or placental weight. It is therefore crucial that obstetricians have an increased awareness for the problem of obesity and pregnancy.
