No weight gain during pregnancy has impact on development of allergic diseases in newborns: Study

Ontario [Canada], January 1 : According to a study by the University of Ottawa, a mother's weight before pregnancy may impact their newborn's risk of developing allergic diseases in early childhood, whereas weight gain during pregnancy did not seem to have the same effect.
The research has been published in the 'Perinatal Epidemiology Journal'
Here are the key points from the study, led by Sebastian Srugo, who was a graduate student in the School of Epidemiology and Public Health at the Faculty of Medicine:
1. No link was found between a mother's weight gain during pregnancy and childhood allergic disease.
2. Children born to obese mothers in pregnancy were more likely to develop asthma, but slightly less likely to develop dermatitis and anaphylaxis. Specifically, children born to obese mothers before pregnancy had an 8 per cent higher risk of developing asthma.
3. Approximately half of the infants were born to overweight or obese mothers and a third to mothers who gained excess weight during pregnancy.
4. Mothers were entering pregnancy overweight/obese, gaining excess weight during pregnancy, and many children are developing the allergic disease in early childhood.
5. In Canada, approximately 30 per cent of the population suffered from at least one allergic disease, with an even greater prevalence among children.
6. Globally, trends in allergic diseases have reached epidemic proportions, becoming the most common and earliest-onset group of chronic diseases.
