Abstract	Objective The objective of this meta-analysis was to evaluate the association between lean mass and adolescent idiopathic scoliosis (AIS). Methods English databases CENTRAL (The Cochrane Library and the Cochrane Back Review Group Trials Register), MEDLINE, EMBASE, PubMed, Web of Science and Chinese databases CBM, CNKI, VIP, WANGFANG DATA were searched for the relevant case control studies and cross-sectional studies. Two authors selected studies and extracted data independently. Data analysis was performed by Stata15.0. Results Eight studies were included, with a total of 1771 cases of AIS and 6340 controls. AIS group had a lower lean mass compared to control group [MD = − 1.95, 95% CI (− 2.96, − 0.93)]. In the subgroup analysis, female AIS patients had a lower lean mass than the control group [MD = − 1.76, 95% CI (− 2.63, − 0.88)]. The mean difference of lean mass between AIS patients and control group in studies with adults [MD = − 3.96, 95% CI (− 7.26, − 0.67)] is much greater than studies without adults [MD = − 1.04, 95% CI (− 1.59, − 0.49)]. There was not statistically significant in European studies [MD = − 2.10, 95% CI (− 4.35, 0.14)], but in Asian studies lean mass in AIS patients was lower than the control group [MD = − 2.26, 95% CI (− 3.98, − 0.54)]. Study type, gender, age, and geography condition were thought to have no effect on the primary outcome of lean mass by subgroup analysis. Conclusion In the meta-analysis, AIS group had a lower lean mass compared to control group, which indicated that lean mass may be involved in the pathogenesis of AIS. But limited by the number of studies we included; the above conclusions need to be validated by more high-quality studies.
