Evidence-based nutrition - review of epidemiological studies

Results from epidemiological studies are often used to explore the relationships between nutrition and health. The objective of this paper is to provide guidelines for evaluating the quality and strength of evidence from different types of epidemiological studies (including ecological, cross-sectional, case-control, cohort and experimental studies) for conclusions about the relationship between nutrition and health.The discussion include advantages and disadvantages of these different types of studies, exposures, outcomes, the role of chance, bias and confounding factors, recruitment and sampling procedures and criteria, study size and power, measurement error (random and systematic), time effects, observer and participant effects, compliance, as well as analysis and interpretation of results. A checklist for reviewing epidemiological studies is given as guide to assess the quality of the data and the suitability of the study results for specific conclusions

Evidence-based nutrition

The evidence-based approach has recently been implemented to translate the vast body of literature available into effective action aimed at addressing the pressing nutritional problems that affect populations.In this paper, the first in a series on the topic, the meaning of evidence-based nutrition (EBN) is clarified and the broad outlines of how to review and interpret both individual papers and reviews of a collection of papers is discussed.The objectives of the EBN approach and the steps to follow in the process are outlined. A useful checklist for the critical appraisal of research papers is given and criteria for reviewing reviews of all relevant available information are discussed. The benefits of the EBN approach are highlighted
