Methodologies and Messages in Iranian Articles on Maternal Care, Diabetes Mellitus, and Tuberculosis, Published in 2001 – 2006

Abstract

Introduction: An article with a clear message can transfer research knowledge better. However, this is the case when the message suits the type of  study methodology (research design) and its results. The objective of  this study was to assess the presence of  message articles and the type of  study methodologies.
Methods: Articles published between 2001 and 2006, on
maternal care, diabetes, and tuberculosis, which were based on
studies performed on the Iranian population were investigated. A systematic search was performed in foreign databases ‘Pubmed, Medline, and Embase’, and national databases ‘Iranmedex, SID (Scientific Information Database), and Iranpsych’. Seven hundred and ninety‑five articles were examined for the type of  study methodology and presence of  an actionable message (one that specifies what and how an action should be carried out).
Results: Among the 795 articles accessed, cross‑sectional studies were the most frequent (50.9%) and systematic reviews were the least frequent (0.4%). Cohort cases were observed in 6.9% of  the cases. Actionable messages were observed in 22.1% of  all the cases and 24.7% of  the cross‑sectional studies.
Conclusions: Cohort studies increased from 5% in 2001 to 6.9%
in 2006, but the shortage of  systematic reviews represented a major weakness in the country’s knowledge production process. Studies with a higher level of  evidence such as systematic reviews, and cohort and interventional studies should be among the priorities of  knowledge production in the country.
