Metabolic Syndrome Increases the Risk for Knee Osteoarthritis: A Meta-Analysis.
EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE(2016)
摘要
Background. Studies revealed that metabolic factors might contribute substantially to osteoarthritis ( OA) pathogenesis. There has been an increasing interest to understand the relationship between knee OA and the metabolic syndrome ( MetS). The purpose of this study was to explore the association between metabolic syndrome and knee osteoarthritis using meta-analysis. Methods. Databases, including PUBMED, EMBASE, and the Cochrane Library, were searched to get relevant studies. Data were extracted separately by two authors and pooled odds ratio ( OR) with 95% confidence interval ( CI) was calculated. Results. The meta-analysis was finished with 8 studies with a total of 3202 cases and 20968 controls finally retrieved from the database search. The crude pooled OR is 2.24 ( 95% CI = 1.38-3.64). Although there was significant heterogeneity among these studies, which was largely accounted for by a single study, the increase in risk was still significant after exclusion of that study. The pooled adjusted OR remained significant with pooled adjusted OR 1.05 ( 95% CI = 1.03-1.07, p < 0.00001). No publication bias was found in the present meta-analysis. Conclusions. The synthesis of available evidence supports that metabolic syndrome increases the risk for knee osteoarthritis, even after adjustment for many risk factors.
