TY - JOUR T1 - Selecting appropriate study designs to address specific research questions in occupational epidemiology JF - Occupational and Environmental Medicine JO - Occup Environ Med SP - 633 LP - 638 DO - 10.1136/oem.2006.029967 VL - 64 IS - 9 AU - Harvey Checkoway AU - Neil Pearce AU - David Kriebel Y1 - 2007/09/01 UR - http://oem.bmj.com/content/64/9/633.abstract N2 - Various epidemiological study designs are available to investigate illness and injury risks related to workplace exposures. The choice of study design to address a particular research question will be guided by the nature of the health outcome under study, its presumed relation to workplace exposures, and feasibility constraints. This review summarises the relative advantages and limitations of conventional study designs including cohort studies, cross-sectional studies, repeated measures studies, case-control (industry- and community-based) studies, and more recently developed variants of the nested case-control design: case-cohort and case-crossover studies.
