摘要Introduction: Vitamin D (Vit-D) insufficiency is highly prevalent in the paediatric population. This study aimed to review
the literature on the association between serum 25(OH)Vit-D levels and the risks of fractures in children and adolescents, and to explore the sources of heterogeneity on reported results.

Materials and Methods: Systematic review and meta-analysis for observational studies comparing serum Vit-D levels
between fracture and non-fracture paediatric cases were conducted. Results: Analysis on 15 case-control and five cross-sectional studies reported before 24 February 2020 and involving a total of 7184 subjects (2709 fracture cases and 4475 controls) suggested that serum 25(OH)Vit-D was lower in fracture cases than in controls (pooled mean difference (MD): -3.28 nmol/L; 95% confidence interval (CI): -5.67 to -0.89). The pooled MD were -15.18 nmol/L (95% CI: -20.60 to -9.76) and 1.61 nmol/L (95% CI: -6.33 to 9.54) in summer and in winter, respectively. Rate of Vit-D deficiency (25(OH)Vit-D<50 nmol/L) was higher in fracture cases than in controls (pooled odds ratio=1.25; 95% CI: 1.06-1.48; p=0.01). Rate of Vit-D insufficiency (25(OH)Vit-D between 52.5 and 72.5 nmol/L) was similar between fractures cases and controls (pooled odds ratio=1.13; 95% CI: 0.78-1.63; p=0.53).

Discussion and Conclusion: This systematic review indicated that serum 25(OH)Vit-D levels were lower in children
with fractures, particularly in summer. Children with fractures were more likely to have 25(OH)Vit-D levels less than
50 nmol/L.
