Objectives: Exposure assessment using questionnaires is effective in large-scale epidemiological studies.
However, a limited number of studies have evaluated the questionnaires used in epidemiologic studies in termsof occupational and environmental exposure. The purpose of this study was to summarize and evaluatequestionnaire items included in major epidemiological studies conducted in Korea with regard to occupationaland environmental exposure.
Methods: A total of 12 studies (four cohort studies, six large-scale cross-sectional surveys, and two panelstudies) were selected for this study. Various questionnaire items related with occupational and environmentalitems were collected and summarized into tables.
Results: Although job type and address were included in almost all of the studies, the information onoccupational or environmental exposure to specific risk factors was collected in a limited number of studies.
Moreover, questionnaire items were not standardized, warranting a continuous effort to develop questionnairesand evaluate their validity.
Conclusion: Our results suggest that validated questionnaire items focusing on occupational and environmentalexposure need to be developed in order to enhance the availability of the information collected from questionsin epidemiological studies.Objectives: Exposure assessment using questionnaires is effective in large-scale epidemiological studies.
