Measurement of data obsolescence in public health journals of Mexico

Resumen

Introduction: In the process of scientific communication, obsolescence is defined as the decrease of information validity or usefulness over time. Objective: To determine the degree of obsolescence of information published in three public health journals in Mexico and quantify their annual utility loss in a given period. Method: Multisynchronous bibliometric study of indexed, peer-reviewed and active journals, with more than 30 years of existence. Analyzed variables: source articles’ year of publication, references’ year, age of the latter. From the references of original articles published between 2008 and 2013, variables and indicators were obtained according to Brooks’ mathematical model and the half-life method. Results: Obsolescence measurements and variables’ mean values were obtained for each journal. The values obtained indicate a half-life of 7.5 years; actuality average, 39.76%; aging factor, 91.15%; loss of usefulness, 8.85% per year, which represents obsolescence of literature on this subject and country. Conclusions: This study delineates an obsolescence profile for each journal: the aging factor and annual loss of usefulness are consistent with those shown by the leading public health journals in Latin America and Spain.
