228897 Increased weight status is significantly associated with pediatric forearm fractures from standing height falls vs. major traumaMonday, November 8, 2010
Background/Purpose: Rates of both pediatric forearm fractures and obesity are increasing. Among adults, radius fractures from low energy falls are associated with bone fragility. Among children, increased weight status may increase forearm fracture risk, particularly at low fall heights. Weight for age/gender > 95th percentile has a high specificity (96%) and reasonable positive predictive value (80%) in identifying obese children (body mass index > 95th percentile).
Methods: Retrospective analysis of patients 0-17 years evaluated for isolated forearm fractures at a large urban pediatric emergency department from 2003-2006. Bivariate analyses were used to compare fractures resulting from major trauma to those resulting from a fall from standing height. Results/Outcomes: Of 929 forearm fractures, there were 54 (5.8%) with major trauma and 226 (24.3%) with a fall from standing height. The overall cohort was 64% male, 80.1% African-American, and had a mean age of 8.4 (± 3.9) years. Fall from standing height cases were significantly older [10.4 (± 3.4) vs 7.4 (± 4.2) years, p< 0.05], had significantly more radius-only fractures, and had greater odds of having a weight for age/gender >95th percentile [OR 2.41 (95% CI 1.08-5.42)]. These groups did not differ in gender, race/ethnicity, or injury season. Conclusions: Fall from standing height is a common mechanism of pediatric forearm fracture and is significantly associated with increased weight status and radius-only fractures. These data provide additional rationale for aggressively addressing obesity and investigating bone health among affected children.
