Summary
Introduction:
Despite the growing number of studies with a characteristic element of spatial analysis, the application of the techniques is not always clear and its continuity in epidemiological studies requires careful evaluation.
Objective:
To verify the spread and use of those processes in national and international scientific papers.
Method:
An assessment was made of periodicals according to the impact index. Among 8,281 journals surveyed, four national and four international were selected, of which 1,274 articles were analyzed regarding the presence or absence of spatial analysis techniques.
Results:
Just over 10% of articles published in 2011 in high impact journals, both national and international, showed some element of geographical location.
Conclusion:
Although these percentages vary greatly from one journal to another, denoting different publication profiles, we consider this percentage as an indication that location variables have become an important factor in studies of health.
