Background: Sedentary behaviour (SB) is a potential risk factor for suboptimal bone deposition in youth.
Results: Total SB was negatively associated with lower extremity bone outcomes, while no association was observed with total body bone outcomes. Insufficient evidence was found for an association between total SB and lumbar spine bone outcomes.
Conclusion: This review highlights the heterogeneity of the available evidence and emphasizes the need for well-designed studies.
