Large babies born in mothers with diabetes have almost three times the risk of excessive body weight or obesity, according to scientists.
The same study showed that breastfeeding in the first five months of life reduced the chance that a child would be obese and overweight by about 25%.
Scientists studied more than 81,000 pre-school children born between January 2005 and August 20013 in Alberta, Canada.
Children were divided into different categories according to their height and weight, their size at birth and whether their mothers had diabetes or not during their pregnancy.
The analysis showed that compared to children born normally of mothers without diabetes, those who were at birth above the average and whose mothers had diabetes had a 2.79-fold greater likelihood of overweight or obesity.
A further study showed that at birth she was more likely to have a gestational age (LGA) of 39% on the risk of childhood obesity.
The researchers considered cases of type 1 and type 1 diabetes. The link with childhood obesity was stronger for mothers with type 2 illness.
Researchers led by dr. Padma Kaul from the University of Alberta wrote in Diabetologia: "We hope that these findings will strengthen public health campaigns that advise women planning a pregnancy, such as smoking, other lifestyle choices, their weight before pregnancy, and weight gain, and controlling blood sugar during pregnancy can significantly affect the future health of their children.
