Retraction
The Publisher and Editor regretfully retract this article[1] because the peer-review process was inappropriately influenced and compromised. As a result, the scientific integrity of the article cannot be guaranteed. A systematic and detailed investigation suggests that a third party was involved in supplying fabricated details of potential peer reviewers for a large number of manuscripts submitted to different journals. In accordance with recommendations fromCOPEwe have retracted all affected published articles, including this one. It was not possible to determine beyond doubt that the authors of this particular article were aware of any third party attempts to manipulate peer review of their manuscript.

Abstract
BACKGROUND:
The purpose of this study was to assess the association between leisure-time physical activity (LPA) and the risk of metabolic syndrome (MS).
METHODS:
Prospective cohort studies of the association between LPA and the risk of MS were retrieved from the PubMed and Embase databases up to 12 August 2013. The statistical analysis in this study was performed using Stata 11.0 software. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the effect of LPA on the risk of MS.
RESULTS:
A total of five articles were included in this meta-analysis. The overall effect sizes indicated that people with moderate level LPA (OR = 0.89, 95% CI: 0.82 to 0.96, P = 0.003) or high level LPA (OR = 0.58, 95% CI: 0.38 to 0.89, P = 0.012) had lower risk of MS than people with low level LPA. The subgroup analysis by gender showed that high level LPA could reduce the risk of MS in populations of different genders (female, OR = 0.20, 95% CI: 0.08 to 0.49, P <0.001; male, OR = 0.59, 95% CI: 0.43 to 0.82, P = 0.002). However, compared with low level LPA, Americans with high level LPA did not significantly reduce the risk of MS (OR = 0.59, 95% CI: 0.43 to 0.82, P = 0.002), while a significant decrease of the risk of MS was found in Europeans with high level LPA (OR = 0.49, 95% CI 0.32 to 0.77, P = 0.002) in the subgroup analysis by region.
CONCLUSIONS:
The meta-analysis confirmed that a moderate and high level of LPA could reduce the risk of MS.
