MDC dietary database

A range of researchers with different specialties have expressed an interest in the MDC dietary data:

  • Nutritional epidemiologists with experiences from other dietary datasets.
  • Nutritional researchers established in clinical or experimental research, but with little experience of epidemiology.
  • Epidemiological researchers with limited experience of food science and nutrition.
  • Clinical researchers with limited experience of food science, nutrition and/or epidemiology.
  • Experimental researchers having defined clear biological hypotheses, but with limited experience of food science, nutrition and epidemiology.

Regardless of specialty, the very first step in the application process, if you wish to examine MDC dietary data, is to study the document “The modified diet history methodology of the Malmö Diet and Cancer cohort – including recommendations on how to handling dietary data”. The specific characteristics of the MDC dietary history methodology will have important implications both for the design and conduct of analytical projects.

Also, a good grip of the whole database will without doubt help the planning of the dietary analysis, since a large number of variables are needed to handle biases (exclusions/inclusions, stratification e t c) and to control appropriately for potential confounding factors.

Please follow the following steps:

  • Think through the research questions carefully, and how these can be concretized into analytical procedures.
  • Scrutinize the available variable lists (both general data and dietary data) to find out what information is available, and what is possible to do within the MDC.
  • Discuss with the nutritional epidemiologists that are familiar with the data set.

The application to the Steering Committee should contain:

  1. a project plan that delineates the major steps in statistical analysis; and
  2. a complete list of required variables (exposures and potential confounders) identified from the dietary and general databases using the MDCS variable names, and end- point variables from the endpoint registries.
