Cross-sectional studies involve identifying a defined population at a given point in time and measuring a range of variables on an individual basis which can include current and past dietary exposures and well as health outcomes and disease status. They are also known as prevalence surveys. They include a type of migrant study. This chapter considers the use and limitations of cross-sectional studies and their value in generating hypotheses. It provides details of their design (including a flow chart and a consideration of the choice of variables) and discusses the approaches to analysis.

Keywords: cross-sectional study; prevalence survey; migrant study; design; limitations; hypothesis generating; confounding
