Background: After several decades of increasing prevalence, recent evidence suggests a levelling of obesity rates in some groups, although little is known about trends in children under 5 years of age.
Aim: To investigate the prevalence, trends and sociodemographic correlates of overweight and obesity in Australian preschool children between 1999 and 2007.
Methods: Child anthropometric and demographic data were extracted from records of routine maternal and child health consultations for children aged 2 and 3.
