Medical recommendations on weight gain in the mom should be taken into account to avoid complications in pregnancy and childbirth, but also to avoid problems in the baby. According to a study just published in The Lancet, pregnant women are overweight have a higher risk of giving birth to babies with more birth weight and increased risk of the baby developing obesity in the future.
The study investigators have been at Children's Hospital Boston (United States) has been quite broad. They have been based on data from 513 501 1.16475 million pregnant women and children who have given birth at term, being 37 and 41 weeks, excluding diabetic mothers and babies born with an extremely high or low weight.
They have concluded that gaining too much weight in pregnancy is associated with a higher weight of the baby at birth, regardless of genetic factors. We analyzed cases of brothers and has been with the same genetic load, the greater the weight gain of mother during pregnancy, the greater the weight of the baby.
On average, pregnant women increased by 13.6 kg. About 12 percent of mothers has increased more than 20 kilos during pregnancy and 12 percent of children born weighing less than 3.9 kilos.
They found that mothers increased between 20 and 22 kilos were 1.7 times more likely to give birth to a baby with one overweight compared to those that only increased between 8 and 10 kilos. While they won more than 24 kilos multiplied by 2.3 times the risk.
It is believed that overweight during pregnancy affects the uterine environment, causing changes in the hypothalamus, pancreatic islet cells in the fatty tissue and other cellular systems involved in regulating body weight.
Hence the importance of maintaining a healthy weight during pregnancy. The balanced diet during pregnancy is essential for the future health of the baby, both at birth and in the future, as they also relate more kilos of pregnant women with baby diseases in adulthood such as obesity, asthma and cancer.
