RESEARCH DESIGN AND METHODS The analyses included 105,588 participants from web-based NutriNet-Santé (France, 2009–2022; mean age 42.5 ± 14.6 years, 79.2% women). Repeated 24-h records, including brands commercial names industrial products, merged with qualitative quantitative food additive...
Background Nitrites and nitrates occur naturally in water soil are commonly ingested from drinking dietary sources. They also used as food additives, mainly processed meats, to increase shelf life avoid bacterial growth. Experimental studies suggested both benefits harmful effects of nitrites exposure on type 2 diabetes (T2D) onset, but epidemiological clinical data lacking. We aimed study these associations a large population-based prospective cohort study, distinguishing foods...
Abstract Objective To assess the associations between exposure to food additive emulsifiers and risk of cardiovascular disease (CVD). Design Prospective cohort study. Setting French NutriNet-Santé study, 2009-21. Participants 95 442 adults (>18 years) without prevalent CVD who completed at least three 24 hour dietary records during first two years follow-up.

When considering health-related impacts of foods, nutrient profile and (ultra)processing are two complementary dimensions. The Nutri-Score informs on the dimension. Recently, mounting evidence linked ultraprocessed food consumption to various adverse health outcomes, independently their profile. To inform consumers about each these dimensions food, we tested, in a randomised controlled trial, if graphically modified version 'Nutri-Score V.2.0', including black 'ultraprocessed' banner, would...
Nutritional factors are essential for the functioning of immune system and could therefore play a role in COVID-19 but evidence is needed. Our objective was to study associations between diet risk SARS-CoV-2 infection large population-based sample.Our analyses were conducted French prospective NutriNet-Santé cohort (2009-2020). Seroprevalence anti-SARS-CoV-2 antibodies assessed by ELISA on dried blood spots. Dietary intakes derived from repeated 24 h dietary records (at least 6) two years...
Background: To estimate the seroprevalence of SARS-CoV-2 infection in May-June 2020 after lockdown adults living three regions France and to identify associated risk factors.Methods: Participants a survey on COVID-19 from an existing consortia general adult population cohorts Ile-de-France (IDF) or Grand Est (GE) - two with high rate COVID-19, Nouvelle-Aquitaine (NA) – low rate, were asked take dried-blood spot (DBS) for anti-SARS-CoV-2 antibodies.The primary outcome was positive ELISA IgG...
Abstract ABO blood type has been reported as a potential factor influencing SARS-CoV-2 infection, but so far mostly in studies that involved small samples, selected population and/or used PCR test results. In contrast our study aimed to assess the association between types and infection using seroprevalence data (independent of whether or not individuals had symptoms sought for testing) large population-based sample. Our included 67,340 French participants SAPRIS-SERO multi-cohort project....
The individual results of SARS-CoV-2 serological tests measured after the first pandemic wave 2020 cannot be directly interpreted as a probability having been infected. Plus, these are usually returned binary or ternary variable, relying on predefined cut-offs. We propose Bayesian mixture model to estimate infection probabilities, based 81,797 continuous anti-spike IgG from Euroimmun collected in France wave. This approach used and was therefore not diagnostic Cumulative incidence, which is...
