About the research

Full project title: Scoping existing dietary data available in CLOSER to support cross-cohort research questions

Table with full plates of food

This project will help researchers examine the relationship between diet and health with ageing by documenting and comparing available dietary intake information across eight CLOSER studies. This clarification and documentation of dietary measures in the studies is an essential step for any cross-cohort comparisons of diet and dietary patterns. As an example of the research that is possible using the dietary data contained in the CLOSER studies, the project will explore the association between diet across the lifecourse and allostatic load (the wear and tear on the body), as a marker of ageing.

Although some of the CLOSER studies have included self-reported measures of dietary intake, this project will be the first to fully explore and compare dietary intake information across the eight studies listed below. Resources from this project will help researchers to address important questions about the links between diet and health with ageing.
