UNLABELLED: In this meta-analysis, we analyzed 9 cross-sectional studies for an association between type 1 diabetes mellitus (T1DM) and bone mineral density (BMD) in children. We found that BMD Z-scores were significantly reduced in children with T1DM.
INTRODUCTION: Recent cross-sectional studies have examined how T1DM influences bone health in children and adolescents, but the relationship between T1DM and BMD remains unclear due to conflicting reports.
METHODS: In this meta-analysis, we systematically searched PubMed, Cochrane library, and Web of Science databases (for publications through March 12, 2020), and calculated weight mean difference (WMD) along with 95% confidence intervals (CI) using a random-effects model. Heterogeneity was evaluated using the I2 method. The Newcastle-Ottawa Scale was used to assess the quality of the included studies.
RESULTS: Data were analyzed from 9 eligible studies, including a total of 1522 children and adolescents. These data were tested for an association between T1DM and BMD. This analysis found a significant decrease in BMD Z-score in the whole body (pooled WMD, - 0.47, 95% CI, - 0.92 to - 0.02, I2 = 80.2%) and lumbar spine (pooled WMD, - 0.41, 95% CI, - 0.69 to - 0.12, I2 = 80.3%) in children and adolescents with T1DM, which was consistent in published studies from Asia and South America, but inconsistent in the North America and Europe. Importantly, the differences in BMD Z-scores were independent of age, level of glucose control (HbA1c), and prepubertal stage. Sensitivity analyses did not modify these findings. Funnel plot and the Egger test did not reveal significant publication bias.
CONCLUSION: This meta-analysis suggests that T1DM may play a role in decreasing BMD Z-scores in the whole body and lumbar spine in children.
