NutriNet-Sant A Large Web-Based Study Investigating Nutrition, Health, and Dietary Patterns in Adults

What this Trial Is About

The NutriNet-Sant study is a large web-based research project launched in France in 2009 to explore the connections between nutrition and health. It includes over 171,000 participants and focuses on detailed assessment of dietary habits and nutritional exposure. The study collects extensive data on socio-demographic, lifestyle, and health factors to understand how nutrition relates to health outcomes over time. Participants regularly complete online questionnaires about their diet, physical activity, and health status. Dietary intake is measured through a series of three non-consecutive 24-hour dietary records every six months, while other lifestyle and health information is updated yearly or biannually. A subgroup provided biological samples stored for further analysis. Major health events like cancers and cardiovascular diseases are reported and validated using medical records and national databases. Participants contribute data through repeated online questionnaires on diet, physical activity, and health status, including mental health and quality of life measures. Health events, mortality, and chronic conditions are tracked continuously. The study uses questionnaires every six months to monitor various health outcomes over up to 10 years. This ongoing follow-up allows researchers to study long-term nutritional impacts on health in a large population.
