Abstract
Objective To determine among children with normal birth weight if maternal hyperglycemia and weight gain independently increase childhood obesity risk in a very large diverse population Methods Study population was 24141 individuals mothers and their normal birth weight offspring born 1995–2003 among a diverse population with universal GDM screening 50g glucosechallenge test GCT 3 h 100 g oral glucose tolerance test OGTT if GCT+ Among the 13037 fullterm offspring with normal birth weight 2500–4000 g annual measured height/weight was ascertained between ages 2 and 10 years to calculate genderspecific BMIforage percentiles using USA norms 1960–1995 standard Results Among children who began life with normal birth weight we found a significant trend for developing both childhood overweight 85 ile and obesity 95 ile during the first decade of life with both maternal hyperglycemia normal GCT GCT+ but no GDM GDM and excessive gestational weight gain 40 pounds 181 kg p 00001 for both trends These maternal glucose and/or weight gain effects to imprint for childhood obesity in the first decade remained after adjustment for potential confounders including maternal age parity as well as prepregnancy BMI The attributable risk for childhood obesity was 285 95 CI 159–411 for GDM and 164 95 CI 94–232 for excessive gestational weight gain Conclusions for Practice Both maternal hyperglycemia and excessive weight gain have independent effects to increase childhood obesity risk Future research should focus on prevention efforts during pregnancy as a potential window of opportunity to reduce childhood obesityThis work is supported by a Research Award from the American Diabetes Association and grant award 1R01HD058015 from the Eunice Kennedy Shriver National Institute of Child Health and Human Development both awards to TH We would also like to thank Martie Sucec for her editorial review and Robin Daily for her formatting assistance
