AbstractSeveral studies have reported a potential association between the gut microbiota (GM) and scoliosis. However, the causal relationship between GM and scoliosis and the role of inflammatory factors (IFs) as mediators remain unclear. This study aimed to analyze the relationship between GM, IFs, and scoliosis. We investigated whether IFs act as mediators in pathways from the GM to scoliosis. Additionally, using reverse Mendelian randomization (MR) analysis, we further investigated the potential impact of genetic predisposition to scoliosis on the GM and IFs. In this study, we searched for publicly available genome-wide association study aggregate data and utilized the MR method to establish bidirectional causal relationships among 211 GM taxa, 91 IFs, and scoliosis. To ensure the reliability of our research findings, we employed 5 MR methods, with the inverse variance weighting approach serving as the primary statistical method, and assessed the robustness of the results through various sensitivity analyses. Additionally, we investigated whether IFs mediate pathways from GM to scoliosis. Three negative causal correlations were observed between the genetic predisposition to GM and scoliosis. Additionally, both positive and negative correlations were found between IFs and scoliosis, with 3 positive and 3 negative correlations observed. IFs do not appear to act as mediators in the pathway from GM to scoliosis. In conclusion, this study demonstrated a causal association between the GM, IFs, and scoliosis, indicating that IFs are not mediators in the pathway from the GM to scoliosis. These findings offer new insights into prevention and treatment strategies for scoliosis.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
