Abstract
This study was carried out to identify the scope of epidemiologic studies and appropriate application of epidemiologic concepts in Korea by reviewing papers entitled as epidemiological study, which have been published in academic and professional journals from 1960 to the present.
Even with the limitation of this study due to exclusion of all epidemiological studies that did not have the subject title and to the crude classification of epidemiologic concepts examined, the result may be valuable for the institutes of educating health personnel in further planning of epidemiology teaching/training.
The results obtained are summarized as followings:
1. Total research papers with subject title as epidemiological study reviewed were 168 among which 55 papers were study of hospital data and 113 papers were community data. The distribution of the papers by the scope of the study showed that 18 percent of 168 papers was simple numerator analysis without control group, not belonging to epidemiologic study; about 20% out of 168, 25 papers from hospital data and 8 papers from epidemic study which were also the numerator analysis only, had some contents of natural history; in 113 community studies including 17 epidemic studies and 96 cross-sectional studies only 9 papers were incidence study and all 96 papers were prevalence study of decriptive nature. There was no single paper that dealt with more sophisticated research methods such as cohort study, case control study, intervention study, and even clinical trials.
2. The research papers based on hospital data expressed and interpreted relative frequency by various variables as incidence rate in 78% of 55 papers, explaining the variables as contributing or risk factors with probability concepts even without control group. Furthermore, the papers that the interpretation and conclusion derived from the data were justifiable were less than 40%.
