Mothers who suffer from gestational diabetes during pregnancy may lead to an increased risk of obesity in pre-teens, according to a study. The new research published in the journal Diabetologia suggested that prenatal, perinatal and postnatal environmental factors impact childhood obesity and intrauterine exposure to maternal gestational diabetes mellitus (GDM) places offspring at an increased risk of long-term adverse outcomes. The study is based on a multinational cross-sectional research conducted at urban and suburban sites in 12 countries which included 4,740 children. he authors considered various factors like maternal age at delivery, education, infant feeding mode, gestational age, number of younger siblings, moderate-to-vigorous physical activity, sleeping time, sex and birth-weight while doing the study. While the prevalence of reported maternal GDM was 4.3 per cent, the overall prevalence of childhood obesity, central obesity and high body fat was 12.3 per cent, 9.9 per cent and 8.1 per cent, respectively.
