Life course epidemiology and analysis

Life course epidemiology approaches disease aetiology and prevention from the perspective of risk and protective factors that influence health and disease throughout the lifespan. The integration of a life course approach to epidemiologic research is central for identifying effective policies and programmes to promote population health and health equity. This chapter will introduce life course concepts and models and analytical approaches for research on life course determinants of health. It will discuss threats to causal inference, approaches for overcoming these difficulties, and future directions in life course epidemiology. For example, in addition to expanding epidemiologic research with a life course perspective to include people with diverse life experiences, new areas of development include life course research extending beyond one human lifespan to include intergenerational and transgenerational life course research, as well as the application of innovative methods.
