The purpose of this study is to clarify the association between serum Fe levels and Obesity using a meta-analysis approach. We searched eligible papers on the relevance published between 2006 and 2014 from the PubMed and the Chinese National Knowledge Infrastructure. Review Manage software was used to collect and analysis the date cited in the papers.6 eligible articles with 934 subjects from 40 case-control studies were identified. Overall,polled analysis indicated that subjects with obesity had lower Fe levels than healthy controls [standardized mean difference (SMD) = -0.738,95%confidence interval (CI) = (-1.228,-0.247)]. Thus, dietary supplement of Fe is recommended to prevent obesity.

Key words: Fe. Serum. Obesity. Meta-analysis.


RESUMEN

El objetivo de este estudio es determinar la asociación entre los niveles séricos de hierro y la obesidad mediante un metaanálisis. Hemos buscado los documentos sobre la pertinencia, publicados entre 2006 y 2014 por PubMed y China National Knowledge Infrastructure. El examen se utiliza para recoger y gestionar el software de análisis de la fecha citada en los documentos. Se eligieron seis artículos en los que se identificaron 934 sujetos de entre 40 estudios de casos y controles. En general, los encuestados indicaron que los sujetos con obesidad tenían menores niveles de hierro que los controles sanos [diferencia de promedios estandarizados (DPE) = - 0.738,95% intervalo de confianza (IC) = (-1.228,-0.247)]. Por lo tanto, se recomienda un suplemento dietético de hierro para prevenir la obesidad.

Palabras clave: Hierro. Suero. Obesidad. Metaanálisis.
