 The Neutronet's anti-study is a web-based prospective cohort study that aims to investigate the relationship between nutrition, mortality and health outcomes. It will recruit 500,000 volunteers aged greater than or equal to 18 years over five years, with 60% expected to be included and followed up for at least five years. The study will use questionnaires administered via Internet to assess socio-demographic and lifestyle characteristics, anthropometry, health status, physical activity and diet. Surveillance of health events will also be implemented through questionnaires on hospitalisation and medication, and linkage with a national database on vital statistics. Biochemical samples and clinical examination will be collected in a subsample of volunteers. The study's findings will enable identifying nutrition-related risks and protective factors, thereby more clearly elucidating determinants of nutritional status and their interactions. These are necessary steps for further refining nutritional recommendations aimed at improving the health status of populations.
