Physical activity and dietary assessment

The Physical Activity, Nutrition and Dietary Assessment (PANDA) working group is comprised of experts in the fields of nutritional and physical activity epidemiology from the Karolinska Institute in Stockholm, the universities of Gothenburg, Linköping, and Umeå in Sweden, and Cambridge University in the UK. Scientists from the US National Institutes of Health are also collaborators on several of the projects defined below.

The overarching short- to medium-term objectives of the working group are to identify and validate assessment methods for nutritional and physical activity epidemiology which can be implemented into the LifeGene Study. The focus is on defining methods, which adequately balance the requirements for validity, reliability and feasibility in large-scale epidemiology research. To this end, several de novo pilot projects are being conducting. These focus on:

  • the development of novel dietary instruments for example a meal-based food frequency questionnaire
  • the validation of new and existing nutritional and physical activity assessment methods in diverse demographic

        groups, such as pregnant women and children.

Existing studies conducted by members of the working group are also being utilized to develop lifestyle assessment methods suitable for use in other demographic groups within the LifeGene target population.


Our longer term objectives are:

  • to help develop data cleaning and processing pipelines which can handle large volumes of data
  • to help develop novel analytic methods which can be applied to the lifestyle data collected in LifeGene
  • to use the lifestyle assessment data collected in LifeGene to elucidate the etiology of complex disease traits
  • to examine the role of gene-lifestyle interactions in complex disease traits.

Owing to the well defined limitations of traditional assessment methods  in longitudinal observational studies, an aim of the working group is to identify accurate and unbiased assessment methods which might be feasible for use in many thousands of LifeGene participants.
