About the research

This project will help researchers examine the relationship between diet and health with ageing by documenting and comparing available dietary intake information across 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 studies. Resources from this project will help researchers to address important questions about the links between diet and health with ageing.

Studies used

Research outputs

  • Dataset of any harmonised measures with accompanying documentation. If harmonisation of these measures is unsuccessful, information about the data and attempted harmonisation will be documented in the metadata report.

Resource reports

  • Metadata report describing all dietary data and methods of collection to support non-nutrition experts using dietary data across the cohorts.

Papers

Published paper on dietary differences between the cohorts;

Published paper on diet and allostatic load.
