Methodological Innovations Teams
Lifestyle Exposure and Interventions Team (LEI)

Starting date: January 2021

Work Programme

The overall goal of the Lifestyle Exposure and Interventions Team (LEI) is to leverage lifestyle research (e.g. nutrition, physical activity, sedentary behaviour, sleep, and stress research) to enhance the understanding of lifestyle-related cancers and the prevention potential.

LEI will develop and share innovative methods and sustainable evidence-based lifestyle interventions that will help researchers and other relevant stakeholders to support communities with tailored lifestyle recommendations and effective behaviour change strategies for cancer prevention. This will be done via three integrated objectives:

  • enhancing databases of current epidemiological studies with innovative lifestyle behaviour indicators (e.g. food biodiversity and processing, meal timing, circadian rhythm, and stress);
  • developing new observational studies (cohort and case–control designs) in high-, middle-, and low-income settings, considering the emerging lifestyle transitions (e.g. IARC–International Initiative for Pediatrics and Nutrition [IIPAN] programme on nutrition and childhood cancer); and

  • developing sustainable, cost-effective, and wide-reaching lifestyle behaviour change interventions, and evaluating their efficacy for cancer prevention (e.g. the LIFE-SCREEN intervention currently being evaluated in the colorectal cancer screening programme in France).
