Abstract: Introduction: Adolescents with high BMIs are more likely to have lower extremity fractures. However, the association between BMI and fracture risk is not clear at all sites. This study investigated the association between BMI and the risk of fracture at four different sites: hip, clinical spine, wrist, and ankle.
Objective: This study aimed to explore the relationship between Body Mass Index (BMI), weight, and the incidence of lower extremity fractures in adolescents.
Methods: Participants from various age groups, sex, socioeconomic statuses, and physical activity levels. We performed logistic regression analysis to ascertain the correlation between BMI and lower extremity fractures. Furthermore, we investigated the association between BMI, weight, and fracture risk at specific anatomical sites - hip, clinical spine, wrist, and ankle.
Results: Present findings revealed a positive correlation between BMI and lower extremity fractures. Overweight and obese adolescents exhibited 1.3 times and 1.67 times higher odds, respectively, of suffering lower extremity fractures compared to those with normal weight. Regarding site-specific fractures, increased BMI was inversely associated with hip, clinical spine, and wrist fractures, implying a protective effect of higher BMI at these sites. However, ankle fractures demonstrated a positive correlation with weight, suggesting an increased risk with greater weight.
Conclusions: Our study illuminates the multifaceted role of BMI and weight in the incidence of fractures among adolescents. It advocates for the formulation of nuanced and personalized fracture prevention strategies in this age group.
