Background Social jetlag corresponds to the misalignment between biological circadian rhythms and the social rhythm imposed by society, resulting in discrepant activity/sleep schedules during work and free days. It has been associated with worsened biological parameters such as BMI or glycemic control. Eating jetlag is a related yet emerging concep...

Background Circadian rhythm disruption has been associated with higher risks of cardiometabolic diseases and several cancers. Mistimed eating patterns can desynchronize circadian rhythms, and could therefore influence metabolic health. However, long-term associations between meal timing and the metabolic syndrome remain unclear. The aim of this stu...

Background The prevalence of food insecurity (FI) is high and suggested to be growing among university students, with potential detrimental effects on their health status and academic performances. This cross-sectional study aims to identify the socioeconomic, demographic and lifestyle factors associated with FI among university students in a disad...

Background Reducing greenhouse gases emissions (GHGe) requires drastic changes in dietary patterns, notably reducing meat consumption. As the process of change can be experienced as stages, we might wonder what actual changes in diet-related GHGe result from each stage of meat reduction. We therefore aimed to describe levels of diet-related GHGe an...

Introduction et but de l’étude La propagation du coronavirus (COVID-19) a eue pour conséquence la mise en place de mesures strictes de confinement, ayant entraîné des changements dans les comportements alimentaires. Les traits psychologiques sont des déterminants bien connus du comportement alimentaire. L’objectif de cette étude était donc d’étudie...

Introduction et but de l’étude La comorbidité entre les troubles du comportement alimentaire (TCA) et l’anxiété est élevée. De plus, l’anxiété pourrait avoir un impact négatif sur les apports énergétiques. Cependant, il n’existe aucune connaissance sur l’association entre la comorbidité et les apports en macronutriments. L’objectif de cette étude é...

Introduction et but de l’étude L’alimentation apporte les nutriments essentiels au bon fonctionnement du système immunitaire et de nombreuses hypothèses suggèrent ainsi un rôle de la nutrition dans la prévention de la COVID-19. Toutefois, il n’existe pas à notre connaissance de données prospectives à ce sujet. Notre objectif était donc d’étudier le...

Introduction et but de l’étude Certaines études ont rapporté des associations entre l’estime de soi et le statut pondéral, mais les données longitudinales sur les adultes sont rares. L’objectif de cette étude était d’analyser les associations transversales et longitudinales entre l’estime de soi et l’indice de masse corporelle (IMC). Méthodes En 2...

Introduction et but de l’étude Les troubles du comportement alimentaire (TCA) sont aujourd’hui très prévalents dans la population : 8,4 % chez les femmes et 2,2 % chez les hommes. Compte tenu des conséquences délétères potentielles des TCA sur la santé, telles que la dépression ou le risque accru de suicide, il est important d’en comprendre les dét...

Background Age-related hearing loss is prevalent yet insufficiently addressed by public health research. Subjective hearing loss has been highlighted as a key determinant of reduced quality of life, while chronic low-grade inflammation is an established determinant of adverse age-related outcomes. To our knowledge, this study was the first to inves...

Introduction et but de l’étude L’optimisme est un trait psychologique qui fait référence aux attentes positives d’un individu face à une situation donnée ou dans la vie. Il a été associé à moins de maladies cardiovasculaires, un vieillissement en meilleure santé et une plus faible mortalité. Il existe cependant peu de littérature sur les associatio...

Introduction et but de l’étude Les régimes végétariens étant en plein essor dans les populations occidentales, leurs effets sur la santé et les caractéristiques des individus qui les pratiquent sont de plus en plus étudiés. Il est par ailleurs bien établi que l’activité physique (AP) est un facteur préventif des principales maladies chroniques. Il...

Purpose Previous works have been suggested that individual sensory liking is a predictor of dietary intake and weight status, and may consequently influence development of cardiometabolic diseases (CMDs). We investigated the association between sensory liking for fat-and-salt, fat-and-sweet, sweet or salt and the onset of hypertension, diabetes and...

Abstract Background Dispositional optimism is a psychological trait that has been associated with positive health outcomes such as reduced risk of cardiovascular diseases. However, there is little knowledge on the relationship between optimism and dietary intake in the population. The objective of this cross-sectional study was to assess whether op...

Organic food consumption has risen in many countries during the past decades, but individual motives leading to these choices remain unclear. This study aimed to evaluate the associations between cognitive restraint (CR), history of dieting and organic food intake. This cross-sectional analysis included 20,085 organic food consumers from the NutriN...

Purpose: Rebalancing the contribution of animal- and plant-based foods is needed to achieve sustainable diet. However, little is known concerning individual characteristics that may influence intake of plant-based foods and their changes over time. We aimed to assess changes in the contribution of plant-based foods to dietary intake over time and...

Objectives. To assess the effects of the Nutri-Score label (relative to the Reference Intakes label or no label) on the nutritional quality of students’ food purchases. Methods. A 3-arm randomized controlled trial was conducted in France in 2017; 2907 participants were randomized into 1 of the 3 study arms (Nutri-Score, Reference Intakes, no label)...

Background: Impulsivity is a psychological trait linked to health issues such as obesity. However, few studies have explored the relation between impulsivity, dietary intake, and eating disorders (EDs) in a general population. Objective: The aim of this cross-sectional study was to assess whether impulsivity was associated with energy intake, fo...

Background Food preparation behaviors may markedly determine dietary intake and consequently influence weight status. However, the few available studies have found equivocal results. No study has prospectively investigated the association between food preparation behaviors and weight change over time. We estimated the associations of food preparati...

The goal of this study is to examine the extent to which child temperament predicts the adiposity rebound, a steep increase in the body mass index (BMI) between ages 5 and 7 years. If this increase occurs at an earlier age, the risk for later obesity is elevated. To improve the accuracy of the examination, we use a genetically informed design, a si...

Improving food choices represents a major goal for the environment and public health. Consideration of future consequences (CFC) is a psychological construct that distinguishes individuals who adopt behaviors based on immediate needs and concerns from individuals who consider the future implications and consequences of their behavior. The objective...

Introduction et but de l’étude L’impulsivité est un trait de personnalité associé à des comportements alimentaires défavorables pour la santé ainsi qu’à l’obésité. Cependant, peu d’études ont étudié les relations entre l’impulsivité, les consommations alimentaires, et les troubles du comportement alimentaire (TCA) en population générale. L’objectif...

Background On the population level, the association of age and other sociodemographic factors with eating disorders (ED) is unclear. Methods We used cross-sectional data from the French general population-based NutriNet-Santé e-cohort (n=49 603 adults; 76.3% women; mean age=50.4±14.6 years). ED were evaluated in 2014 with the 5-item SCOFF screenin...

Background: Emotional eating (EmE) is characterized by an over consumption of food in response to negative emotions and is associated with an increased weight status. Consideration of Future Consequences (CFC) or a low level of impulsivity could influence the association between EmE and weight status. The objective was to analyze the moderating in...

The ‘French Eating Model’ characterised by structured meals and conviviality has received little attention, although it has been suggested as a potential explanation of the French paradox. This study aims at assessing the adherence to this model in French adults and whether it is associated with weight status. Eating behaviour and, in particular, n...

Background: Few studies have specifically focused on demographic and socio-economic characteristics associated with snacking in adults, whereas their identification could be useful for defining effective public health measures. The aim of our study was to assess the associations of these factors with daily snacking behavior and its dietary quality...

Background: Snacking raises concern since it may lead to an additional energy intake and poor nutrient quality. A snacking occasion can be defined as any eating occasion apart from main meals, regardless of the amount or type of foods consumed. We described the frequency of snacking occasions according to daily timing in French adults, and compare...

The Metabolic Syndrome (MetS) is a major public health burden. Dispositional mindfulness has recently been associated with eating disorders, being overweight, and could therefore be associated with the MetS. We aimed to examine in a cross-sectional design the relationship between mindfulness, the MetS, and its risk factors in a large sample of the...

Background Organic food intake has risen in many countries during the past decades. Even though motivations associated with such choice have been studied, psychological traits preceding these motivations have rarely been explored. Consideration of future consequences (CFC) represents the extent to which individuals consider future versus immediate...

Well-being is often mentioned as an important motive for organic food consumption. Little is known about the relationship between organic food consumption and life satisfaction (a component of well-being). The aim of this study was to investigate the cross-sectional relationship between organic food consumption and life satisfaction. A total of 17,...

Background: Dietary guidelines in France give quantitative recommendations for intake of meat, fish and dairy products whereas consumers are increasingly concerned by the environmental impacts associated with the production of these foods. This potentially leads to consumer dilemmas when purchasing food products. The present study aimed at investi...

Individual characteristics, dietary intake and physical activity influence weight status; however, the contribution of each factor to weight change has not been studied. The objective was to confirm a conceptual framework by simultaneously assessing the relative influence of socioeconomic, psychological and sensory characteristics, physical activit...

Background Sustainability has become a greater concern among consumers that may influence their dietary intake. Only a few studies investigated the relationship between sustainable food choice motives and diet and they focused on specific food groups. Objective This cross-sectional study aimed to assess the associations between food choice motives...

Background: There is a growing trend for vegetarian and vegan diets in many Western countries. Epidemiological evidence suggesting that such diets may help in maintaining good health is rising. However, dietary and sociodemographic characteristics of vegetarians and vegans are not well known. The aim of this cross-sectional study was to describe s...

Introduction et but de l’étude La planification des repas a été suggérée comme une solution pour faire face à la contrainte de temps croissante décrite comme une barrière à la préparation de repas « faits-maison » et qui, de ce fait favoriserait le recours à des aliments préparés industriellement.
