Across the many studies of diabetes and obesity there is variation in the methods used to assess exposures and outcomes. Optimising data for re-use requires harmonisation of related variables with different data sets.

InterConnect has contributed to the development of the Diet, Anthropometry and Physical Activity (DAPA) Measurement Toolkit.

This takes researchers to an inventory of subjective and objective methods, to inform interpretation of existing data and choice of methods that are fit for purpose when planning new studies. Specific content and case studies relating to data harmonisation are included.
