INRAE presentation

The French National Research Institute for Agriculture, Food, and Environment (INRAE) is a major player in research and innovation. It is a community of 12,000 people with 272 research, experimental research, and support units located in 18 regional centres throughout France. Internationally, INRAE is among the top research organisations in the agricultural and food sciences, plant and animal sciences, as well as in ecology and environmental science. It is the world’s leading research organisation specialising in agriculture, food and the environment. INRAE’s goal is to be a key player in the transitions necessary to address major global challenges. Faced with a growing world population, climate change, resource scarcity, and declining biodiversity, the Institute has a major role to play in building solutions and supporting the necessary acceleration of agricultural, food and environmental transitions.

Work environment, missions and activities

Unravelling the complex relationship between what we eat and how long and well we live is a critical challenge in public health. Adherence to healthy dietary patterns has been shown to prevent from diseases and prolong life expectancy 1. This project aims to develop new epidemiological models integrating dietary composition with life-course health dynamics to improve our understanding of the long-term health impact of food choices2.

The appointed candidate will join the PROSPECT team (UMR PNCA, INRAE, AgroParisTech, Université Paris-Saclay ; Head: Prof. François Mariotti) for a period of 14-18 months, collaborating closely with partners from the ANR-funded Transfood project and related initiatives. This  work will mostly be conducted at EREN (U. Sorbonne Paris-Nord, Bobigny, France) for the initial period and then at PNCA (University Paris-Saclay, Campus Agro Paris-Saclay, France).

Your primary responsibilities will include:

  • Leading data analysis on the NutriNet-Santé cohort and INCA 3 Survey 3.
  • Contributing to the development of methods to assess the impact of diet on disease risk and (healthy) life expectancy.
  • Utilizing and potentially expanding upon existing tools and methods within the team.

More specific objectives will focus on:

  • Identify dietary profiles that are contrasted with regard to disease risk on NutriNet-Santé cohort data, using a set of multivariable Cox proportional hazard models to characterize relative risks associated with individual food groups using an aggregate morbi-mortality endpoint. Leverage existing team expertise and tools. This task will be conducted at EREN (Bobigny, France).
  • Evaluate the nutritional characteristics of the dietary profiles that contrast with regards to associated morbi-mortality risks, by exploring dietary and nutrient composition and comparing with diets observed in the INCA3 survey, building upon existing team methods and tools.
  • Assessing the impact of dietary changes on the burden of disease, including life table and life expectancy calculations, utilizing existing tools and methods within the team.
  • Exploring dynamics of life-course health by investigate novel tools and methods to characterize the potential influence of dietary changes on life-course health dynamics. Consider factors such as the time lag between dietary modifications and disease onset, as well as changes in health event distribution.

3 The NutriNet-Santé study is a large web-based longitudinal follow-up of a French population cohort, aiming to explore associations between nutrition and health. The INCA 3 Survey, conducted in 2014-2015, is the latest representative survey of dietary consumption in France.
