Objectives: Our objective was to determine the odds of having an increased weight status among children with upper extremity fracture (UEF) compared with 3 control groups without fractures. Methods: This is a secondary analysis of data from the Pediatric Risk of Admission (PRISA and PRISA II) data sets. Patients without chronic illness between the ages of 5 to 14 years were included in the following groups: (1) UEF study group, (2) upper extremity nonfracture injured control group, (3) minor-head-injured control group, and (4) noninjured probability control group. Weight for age/sex percentiles was used to evaluate weight status. The proportions of patients with weight for age/sex greater than the 50th, 85th, and 95th percentiles were determined. Logistic regression was used to generate odds ratios comparing the UEF group with each control group stratified by age. Results: This analysis included 308 patients in the 5- to 9-year age group and 207 patients in the 10- to 14-year age group. The odds of having a weight greater than the 50th percentile for age/sex were significantly increased among children with UEF aged 5 to 9 years compared with all control groups. There were no significant differences in the corresponding odds ratios for children with UEF aged 10 to 14 years compared with controls. Conclusions: These findings may be related to differential injury mechanisms, mobility patterns, or underlying patient vulnerability to fracture based on weight status and bone qualities in prepubescent versus pubescent populations. Further investigation should explore fracture epidemiology and fracture risk in children stratified by age. © 2011 by Lippincott Williams & Wilkins.
