Bone Health in Children and Adolescents with Type 1 Diabetes: Optimizing Bone Accrual and Preventing Fractures
Abstract
Children and adolescents with type 1 diabetes (T1D) often experience abnormalities in bone health. Studies have consistently demonstrated that youth with T1D have lower bone mineral density (BMD) compared to their healthy peers. Additionally, children with T1D show impaired bone microarchitecture and reduced bone turnover. These factors collectively contribute to an increased risk of fractures across the life span of this population. To optimize bone accrual and reduce fracture risk, several strategies can be employed during childhood and adolescence. First, maintaining good glycemic control is critical, as poor glycemic control has been associated with lower BMD and an increased risk of fractures. Second, specific nutritional recommendations can help improve bone health, including a balanced diet, adequate calcium and vitamin D intake, and careful monitoring of both macronutrient and micronutrient intake. Third, regular physical activity plays a vital role. A systematic review and meta-analysis have shown that youth with T1D are generally less physically active, more sedentary, and have lower cardiorespiratory fitness levels than their non-diabetic peers. This review emphasizes targeted strategies aimed at optimizing skeletal health in the pediatric population with T1D, with a particular focus on the critical roles of glycemic control, nutritional adequacy, and regular physical activity. These modifiable factors may contribute to the reduction of fracture risk across the…
