Intrauterine Exposure to Maternal Diabetes is Associated with Adiposity in Children at 6 Years of Age in China

Abstract

Children born to mothers with gestational diabetes mellitus (GDM) are more likely to exhibit congenital malformations, high birth weight, and obesity and have an increased risk of developing type 2 diabetes in later life. Children who are exposed to maternal diabetes in utero may be 'programmed' for later development of obesity at a critical period of development. Therefore, the purpose of the present study was to examine the associations among adiposity and systolic blood pressure in children and abnormal maternal glucose levels during pregnancy. A total of 856 mother-child pairs were included in the present retrospective study. Eligible pregnant women underwent a standard 75 g oral glucose tolerance test between 24 and 28 weeks' gestation. Anthropometric characteristics of their children were measured at 6 years of age, including body mass index, the sum of subscapular and tricep skinfold thickness, and systolic blood pressure. The result suggests that children exposed to GDM have higher adiposity; prevention of childhood obesity needs to begin early in life for these children.
