Abstract

Context: Several studies have been conducted on the relationship between depression and metabolic syndrome, which have had conflicting results. The purpose of this study was a meta-analysis of studies that have examined the relationship between these two variables. Evidence Acquisition: This meta-analysis systematically reviewed the relationship between depression and metabolic syndrome. Scientific databases including IranMedex, SID, Magiran, Scopus, PubMed, Google Scholar, and Science Direct were searched and 17 articles were extracted from 2000 to 2014. Selected studies data were analyzed using meta-analysis and random effects model. Heterogeneity between the studies was examined using I2. Data were analyzed using STATA software version 12.1. Results: Seventeen studies were analyzed with a sample size of 31880 people. Analysis by the type of studies showed that the relationship between the two variables in cross-sectional studies (OR = 1.51, CI 95 = 1.36 - 1.68) and cohort studies (OR = 1.6, CI 95 = 1.23 - 2.08) was significant. In general, the heterogeneity test results among the studies was not significant (P for heterogeneity = 0.08, I2 = 39.8). Conclusions: There is a relationship between depression and metabolic syndrome. © 2016, Iranian Red Crescent Medical Journal.
