Lane JCE, Butler KL, Poveda‐Marina JL, et al. - Experts aspired to explore whether having an overweight or obese range body mass index (BMI) at time of beginning school was correlated with increased fracture incidence in childhood. In total, 466,997 children (48.6% female) with a validated weight and height measurement within routine health care screening at age 4 years (± 6 months) between 2006 and 2013 were involved, and followed up to the age of 15, migration out of region, death, or until December 31, 2016. Data reported that cumulative incidence of any fracture during childhood was 9.20% for underweight, 10.06% for normal weight, 11.28% for overweight children, and 13.05% for children with obesity. Overall, compared with contemporaries of normal weight, preschool children with an overweight or obese range BMI had increased incidence of upper and lower limb fractures in childhood.
