Background: The multifactorial aetiology of scoliosis is well known. Physical activity is considered both a treatment and causative factor for idiopathic scoliosis; however, evidence for a causal relationship between physical activity levels and idiopathic scoliosis in adolescents is conflicting. Therefore, we aimed to summarise the current evidence regarding the association between adolescent idiopathic scoliosis and physical activity and further to assess whether the relationship is dose dependent. Methods: PubMed, Cochrane, Scopus, and Web of Science databases were searched from 1991 to July 2022 using the following main keywords: adolescent idiopathic scoliosis, physical activity, and risk factors, supplemented with manual searches, secondary citations, and reference searches. The quality of the included literature was evaluated using the Scale for Reporting Observational Studies in Enhanced Epidemiology guidelines. Results: Eight studies were included in this review, of which six reported an association between adolescent idiopathic scoliosis and physical activity levels and two reported no association. One British study reported reduced physical function early in life as a new risk factor for scoliosis onset. Conclusions: Physical activity is strongly associated with adolescent idiopathic scoliosis. Physical activity should be encouraged as it plays an important role in the prevention of adolescent idiopathic scoliosis. Further research is needed to determine the dose-dependent relationship between physical activity and prevention of adolescent idiopathic scoliosis. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
