RESUMEN
OBJECTIVES: Epidemiological data regarding the evolution of problems related to mastication and swallowing with age are lacking. This study aims to (i) describe changes in oral function with age, using data from a large French population, (ii) validate online, self-report uses of an ICF questionnaire in older persons, and (iii) assess whether impairment is related to avoidance of certain foods, xerostomia, body mass index (BMI) and oral health related quality of life (OHRQoL). METHODS: Volunteers aged ≥18 years with internet access completed a series of questionnaires on sociodemographic, anthropometric and oral health characteristics (oral function, Xerostomia Index (XI), OHRQoL, reasons for avoidance of certain food). Oral function was assessed using items derived from the International Classification of Functioning (ICF). Five ICF items related to ingestion function and six items related to activities and participation were used. A validation study was undertaken to identify those with poor chewing ability and low salivary flow amongst older participants reporting impairment. FINDINGS: 39 597 individuals were included. The prevalence of individuals with impairment for ICF items related to ingestion function and oral activity (eating, drinking and speaking), and the percentage of participants with poor OHRQoL increased significantly with age (p < 0.001). Each ICF item was significantly associated with OHRQoL (p < 0.001), XI (p < 0.001), BMI (p < 0.001) and avoidance of certain food due to chewing or swallowing difficulties. CONCLUSION: Overall, 21.5% and 13.5% of the study population had chewing and/or biting impairments respectively, which might affect food selection and consumption. These findings raise individual and population-based issues. Further studies are needed to assess whether impairment in oral function might increase frailty in older individuals, and also to compare data with those from other countries.

BACKGROUND: Both the nutritional quality of the foods consumed (as nutrient composition) and their ultra-processed nature have been linked to health risks. However, the respective contribution of each of these correlated dimensions or their synergy to the overall diet quality has been rarely explored. OBJECTIVE: To identify the respective effects of the nutritional quality of the foods consumed, the ultra-processed nature of foods and their cross-effect contributing to the overall quality of the diet. DESIGN: Cross-sectional observational study. SETTING: Web-based French NutriNet-Santé cohort study. PARTICIPANTS: Participants in the NutriNet-Santé cohort study with at least three available 24 h records as baseline dietary data (N = 98 454 participants). MAIN OUTCOME MEASURES: The overall quality of the diet (qualified using the adherence to the 2017 French national nutrition and health dietary recommendations dietary score PNNS-GS2) was broken down into: (1) an effect of the nutritional quality of the foods consumed (qualified using the modified Foods Standards Agency nutrient profile model (underlying the Nutri-Score) dietary index FSAm-NPS DI); (2) an effect of the ultra-processed nature of the foods consumed (qualified using the proportion of ultra-processed foods consumed UPFp using the NOVA classification), and (3) a cross-effect of both dimensions. RESULTS: The overall effect from the 'nutritional quality of the foods consumed' (FSAm-NPS DI) was 1.10, corresponding to 26% of the total effect; the overall effect from ultra-processed foods consumption was 1.29, corresponding to 30% of the total effect; and cross-effect between nutritional quality of the foods consumed and ultra-processing was at 1.91, corresponding to 44% of total effects. CONCLUSIONS: Our study provides support to the postulate that nutritional quality and ultra-processing should be considered as two correlated but distinct and complementary dimensions of the diet.

INTRODUCTION: Periodontitis, as a chronic, multifactorial inflammatory disease, has complex relationships with other diseases and ultimately with well-being. The aim of this cross-sectional study was to investigate the association between self-report periodontitis, as measured with the recently developed and validated modified Periodontal Screening Score (mPESS), and oral health-related quality of life (OHRQol) in a large population-based sample derived from the French NutriNet-Santé e-cohort. METHODS: The sample was composed of 32,714 adults (75.5% women) with a mean age of 48.8 ± 13.9 years. Periodontitis was assessed based on age, smoking, and oral health status data obtained in 2011-2012, which allowed calculating the mPESS. An mPESS ≥ 5 was used to identify individuals at risk of severe periodontitis (main exposure). OHRQoL was measured with the Oral Health Impact Profile (OHIP-14) (main outcome) and the total score was dichotomized for analysis. Multivariable logistic regression analyses, considering physical health status, dietary and lifestyle confounding variables, were performed. RESULTS: Overall, 6407 participants (19.6%) were at a high risk of severe periodontitis. A total of 7383 participants (22.6%) presented a relatively poor OHRQoL (OHIP-14 > 8, highest quartile). In the multivariable model, each of the following variables was independently and significantly associated with lower OHRQoL: older age (50-64 years), female sex, obesity, snacking between meals, frequent consumption of soft drinks and sweets/chocolate, risk of severe periodontitis, and having < 20 natural teeth were significantly. An mPESS ≥ 5 showed the highest odds for relatively poor OHRQoL (OR = 3.45; 95% CI 3.21-3.72). CONCLUSION: The results support the association between periodontitis and OHRQoL in non-clinical samples. The use of mPESS could be tested in future prevention programs aiming at improving OHRQoL.

BACKGROUND: The food industry uses artificial sweeteners in a wide range of foods and beverages as alternatives to added sugars, for which deleterious effects on several chronic diseases are now well established. The safety of these food additives is debated, with conflicting findings regarding their role in the aetiology of various diseases. In particular, their carcinogenicity has been suggested by several experimental studies, but robust epidemiological evidence is lacking. Thus, our objective was to investigate the associations between artificial sweetener intakes (total from all dietary sources, and most frequently consumed ones: aspartame [E951], acesulfame-K [E950], and sucralose [E955]) and cancer risk (overall and by site). METHODS AND FINDINGS: Overall, 102,865 adults from the French population-based cohort NutriNet-Santé (2009-2021) were included (median follow-up time = 7.8 years). Dietary intakes and consumption of sweeteners were obtained by repeated 24-hour dietary records including brand names of industrial products. Associations between sweeteners and cancer incidence were assessed by Cox proportional hazards models, adjusted for age, sex, education, physical activity, smoking, body mass index, height, weight gain during follow-up, diabetes, family history of cancer, number of 24-hour dietary records, and baseline intakes of energy, alcohol, sodium, saturated fatty acids, fibre, sugar, fruit and vegetables, whole-grain foods, and dairy products. Compared to non-consumers, higher consumers of total artificial sweeteners (i.e., above the median exposure in consumers) had higher risk of overall cancer (n = 3,358 cases, hazard ratio [HR] = 1.13 [95% CI 1.03 to 1.25], P-trend = 0.002). In particular, aspartame (HR = 1.15 [95% CI 1.03 to 1.28], P = 0.002) and acesulfame-K (HR = 1.13 [95% CI 1.01 to 1.26], P = 0.007) were associated with increased cancer risk. Higher risks were also observed for breast cancer (n = 979 cases, HR = 1.22 [95% CI 1.01 to 1.48], P = 0.036, for aspartame) and obesity-related cancers (n = 2,023 cases, HR = 1.13 [95% CI 1.00 to 1.28], P = 0.036, for total artificial sweeteners, and HR = 1.15 [95% CI 1.01 to 1.32], P = 0.026, for aspartame). Limitations of this study include potential selection bias, residual confounding, and reverse causality, though sensitivity analyses were performed to address these concerns. CONCLUSIONS: In this large cohort study, artificial sweeteners (especially aspartame and acesulfame-K), which are used in many food and beverage brands worldwide, were associated with increased cancer risk. These findings provide important and novel insights for the ongoing re-evaluation of food additive sweeteners by the European Food Safety Authority and other health agencies globally.

BACKGROUND: Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) have been shown to be involved in gastrointestinal disorders. In view of their proinflammatory potential and their interactions with the gut microbiota, their contribution to the etiology of other chronic diseases such as cancer has been postulated. However, to our knowledge, no epidemiologic study has investigated this hypothesis so far. OBJECTIVES: Our objective was to investigate the associations between FODMAP intake (total and by type) and cancer risk (overall, breast, prostate, and colorectal) in a large prospective cohort. METHODS: The study was based on the NutriNet-Santé cohort (2009-2020); 104,909 adult participants without cancer at baseline were included in our analyses (median follow-up time = 7.7 y, 78.7% women, mean ± SD age at baseline 42.1 ± 14.5 y). Baseline dietary intakes were obtained from repeated 24-h dietary records linked to a detailed food composition table. Associations between FODMAP intake (expressed in quintiles, Q) and cancer risks were assessed by Cox proportional hazard models adjusted for a large range of lifestyle, sociodemographic, and anthropometric variables. RESULTS: Total FODMAP intake was associated with increased overall cancer risk (n = 3374 incident cases, HR for sex-specific Q5 compared with Q1: 1.21; 95% CI: 1.02, 1.44; P-trend = 0.04). In particular, oligosaccharides were associated with cancer risk: a trend was observed for overall cancer (HR Q5 compared with Q1: 1.10; 95% CI: 0.97, 1.25; P-trend = 0.04) and colorectal cancer (n = 272, HR Q5 compared with Q1: 1.78; 95% CI: 1.13-2.79; P-trend = 0.02). CONCLUSIONS: Results from this large population-based study on French adults from the NutriNet-Santé cohort show a significant association between FODMAP intake and the risk of cancer development. Further epidemiologic and experimental studies are needed to confirm these results and provide data on the potential underlying mechanisms.

BACKGROUND: Resilience, the ability to bounce back or recover from stress, has been associated with several health-related behaviors. However, data on food intake and emotional eating are lacking. OBJECTIVES: The objective of this cross-sectional study was to analyze the associations between resilience and diet quality and ultraprocessed food (UPF) and food group consumption, and to assess whether emotional eating was a mediator of these associations. METHODS: In 2017, 17,840 participants (73.5% female, mean age = 55.4 ± 14.0 y) of the NutriNet-Santé study completed the Brief Resilience Scale, the revised 21-item Three-Factor Eating Questionnaire, and ≥3 self-administered 24-h dietary records. Diet quality was assessed with the modified French National Nutrition and Health Program Guideline Score. Foods and beverages consumed were categorized according to their degree of processing by the NOVA classification. We assessed the association between resilience and emotional eating using linear regression models. We also assessed the mediating role of emotional eating in the associations between resilience and diet quality, energy intake, and UPF and food group consumption, controlling for sociodemographic characteristics. RESULTS: In our study, resilience was negatively associated with emotional eating (P < 0.0001). More resilient participants had greater overall diet quality, greater intakes of seafood, whole-grain foods, fats, unsalted oleaginous fruits, and alcoholic beverages, and lower intakes of UPFs, starchy foods, dairy desserts, sugary fatty products, and sugar and confectionery (all P < 0.05). Emotional eating was a mediator of the inverse associations between resilience and intake of energy, UPFs, dairy desserts, sugary fatty products, and of the positive associations between resilience and alcoholic beverages (all P < 0.05), with a 20-70% mediation. CONCLUSIONS: Our findings showed that resilience was associated with an overall better diet quality in the NutriNet-Santé population-based study. These associations were partially explained by emotional eating. These findings suggest that resilience should be considered in the promotion of healthy dietary habits.The study is registered at clinicaltrials.gov as #NCT03335644.

While food-based dietary guidelines have been widely disseminated for decades to improve nutritional knowledge in the population about healthy diets, more recent interventions such as front-of-pack labelling have made the differences between the two approaches apparent. While food-based dietary guidelines provide the overarching framework and benchmarks for a healthy diet, based on the current knowledge of the associations between various dietary components and health outcomes, front-of-pack labelling provides guidance to select a specific food, either within a food group or among similar foods belonging to various brands. Labelling foods as 'healthy' or 'unhealthy' raises multiple questions on the criteria used to define the terms and the implications of assigning an absolute healthiness value to an individual food in the context of complex diets. Gradual systems may provide more relative assessments and avoid dichotomisation. The present article presents the inherent differences and the complementarity of food-based dietary guidelines and food choice guidance in the context of food labelling.

PURPOSE: Eating disorders (ED) and anxiety impact food choices. In addition, comorbid anxiety seems to increase ED symptoms and severity. However, the association between such comorbidity and dietary intake is unknown. This population-based, cross-sectional study aimed to assess macronutrient intake according to mental health status (i.e., no disorder, pure and comorbid anxiety and ED). METHODS: The study included N = 24,771 participants (74% female, mean age = 53.2 ± 13.7 years) in the NutriNet-Santé cohort, who completed once the trait subscale of the State-Trait Anxiety Inventory (STAI-T; high anxiety: ≥ 40 points) between 2013 and 2016 and the SCOFF questionnaire screening for ED in 2014. The Expali algorithm was applied to categorize ED (no ED; restrictive: RS; bulimic: BL; hyperphagic: HP; other ED). Participants were divided into ten groups by crossing their anxiety status (two groups: low or high) and their ED status (five groups). Macronutrient intakes were evaluated from ≥ 3 24-h dietary records. Analyses of covariance (ANCOVA) and Dunnett-Hsu tests (reference = no disorder) were performed. RESULTS: Significant differences in macronutrient intake were seen between the pure and comorbid forms, especially for RS and HP. Compared to the "no disorder" group, a significantly higher percentage of energy from carbohydrates, higher intakes of total carbohydrates, simple sugars, and plant-based protein, lower intakes of total fat, saturated and monounsaturated fatty acids, and cholesterol were observed in the comorbid anxiety + RS group, but not in the pure RS group. In contrast, significantly lower intakes of added sugar and plant-based protein, and a higher intake of cholesterol were observed in the pure HP group, but not in the comorbid anxiety + HP group. For BL and other ED, similar results were observed between the pure and comorbid forms. CONCLUSION: This large epidemiological study provided some support for differences in macronutrient intake between individuals with pure or comorbid anxiety and ED. Differences in intake were largely dependent on ED type. Future prospective studies and studies using clinically defined anxiety and ED are needed to elucidate causality as well as potential effect modification of the observed associations.

BACKGROUND: Nutritional factors are essential for the functioning of the immune system and could therefore play a role in COVID-19 but evidence is needed. Our objective was to study the associations between diet and the risk of SARS-CoV-2 infection in a large population-based sample. METHODS: Our analyses were conducted in the French prospective NutriNet-Santé cohort study (2009-2020). Seroprevalence of anti-SARS-CoV-2 antibodies was assessed by ELISA on dried blood spots. Dietary intakes were derived from repeated 24 h dietary records (at least 6) in the two years preceding the start of the COVID-19 pandemic in France (February 2020). Multi-adjusted logistic regression models were computed. RESULTS: A total of 7766 adults (70.3% women, mean age: 60.3 years) were included, among which 311 were positive for anti-SARS-CoV-2 antibodies. Dietary intakes of vitamin C (OR for 1 SD=0.86 (0.75-0.98), P=0.02), vitamin B9 (OR=0.84 (0.72-0.98), P=0.02), vitamin K (OR=0.86 (0.74-0.99), P=0.04), fibers (OR=0.84 (0.72-0.98), P=0.02), and fruit and vegetables (OR=0.85 (0.74-0.97), P=0.02) were associated to a decreased probability of SARS-CoV-2 infection while dietary intakes of calcium (OR=1.16 (1.01-1.35), P=0.04) and dairy products (OR=1.19 (1.06-1.33), P=0.002) associated to increased odds. No association was detected with other food groups or nutrients or with the overall diet quality. CONCLUSIONS: Higher dietary intakes of fruit and vegetables and, consistently, of vitamin C, folate, vitamin K and fibers were associated with a lower susceptibility to SARS-CoV-2 infection. Beyond its established role in the prevention of non-communicable diseases, diet could therefore also contribute to prevent some infectious diseases such as COVID-19.

PURPOSE: We investigated the association between the inflammatory potential of the diet and hearing loss in the context of aging. METHODS: We studied 3435 French adults enrolled in the SU.VI.MAX 2 (2007-2009) cohort. The inflammatory potential of the diet was estimated by the Dietary Inflammatory Index (DII®) using ≥ 3 baseline 24-h dietary records. Subjective hearing loss was assessed after a mean of 12.5 ± 0.7 years by 3 individual items (ability to carry a conversation in a noisy setting, frequently asking for repetition, and need to increase the television/radio volume) and by a composite score, dichotomized for analyses. We fit sex-specific multivariable logistic regression models. RESULTS: Compared with males, females had higher DII scores (i.e., more pro-inflammatory diet) and less subjective hearing loss. Among males, a significant positive association between DII (continuous scale) and inability to carry a conversation in a noisy setting was found (OR = 1.10; 95% CI 1.02, 1.18), while the opposite was seen among females (OR = 0.92; 95% CI 0.87, 0.98). Regarding the need to turn up the television/radio volume, a significant positive association with DII (continuous scale) was found only among males (OR = 1.09; 95% CI 1.01, 1.18). A significant association with the subjective hearing loss composite score was found among females (ORQ3 vs Q1 = 0.74; 95% CI 0.57, 0.97). CONCLUSION: The findings among males supported the hypothesis that a pro-inflammatory diet could increase risk of hearing loss, whereas the findings among females were unexpected. This study could provide impetus for future research in sensory disability and aging. TRIAL REGISTRATION: www.clinicaltrials.gov # NCT00272428.

PURPOSE: Red and processed meats are recognized by the International Agency for Research on Cancer as probably carcinogenic and carcinogenic to humans, respectively. Heme iron has been proposed as a central factor responsible for this effect. Furthermore, anxiety affects the intestinal barrier function by increasing intestinal permeability. The objective of this work was to assess how anxiety modifies the association between red and processed meat consumption and cancer risk in the NutriNet-Santé prospective cohort (2009-2019). METHODS: Using multi-adjusted Cox models in a sample of 101,269 subjects, we studied the associations between the consumption of red and processed meat, the amount of heme iron coming from these meats and overall, colorectal, prostate, and breast cancer risks, overall and separately among participants with and without anxiety. RESULTS: An increase in red and processed meat consumption was associated with an increased risk of developing colorectal cancer in the total population (HR for an increase of 50 g/day = 1.18 (1.01-1.37), p = 0.03). After stratification on anxiety, the HR 50 g/day was 1.42 (1.03-1.94, p = 0.03) in anxious participants and 1.12 (0.94-1.33, p = 0.20) in other participants. Similar trends were observed for overall cancer risk. Analyses conducted with heme iron also provided similar results. CONCLUSIONS: Our results strengthen the existing body of evidence supporting that red and processed meat consumption and heme iron intake are associated with an increased risk of overall and more specifically colorectal cancer, and suggest that anxiety modifies these associations, with an increased risk in anxious participants.

BACKGROUND: Studies suggest that anxiety is correlated with eating behavior, however, little is known about the association between anxiety status as predictor of dietary macronutrient intake. The aim of the present study was to investigate the sex-stratified cross-sectional associations of trait anxiety with intake of various macronutrients in a large population-based sample of non-diabetic adults. METHODS: N = 20,231 participants (mean age = 53.7 ± 13.6 years) of the NutriNet-Santé web-cohort, who had completed the trait anxiety subscale of the Spielberger State-Trait Anxiety Inventory (T-STAI; 2013-2016) were included in the analyses. Dietary intake was calculated from at least 3 self-administered 24-h dietary records. The associations of interest were assessed by multiple linear regression stratified by sex, owing to significant interaction tests. RESULTS: In total, 74.3% (n = 15,033) of the sample were females who had a significantly higher mean T-STAI score than did males (39.0 versus 34.8; p < 0.01). Among females, the fully-adjusted analyses showed significant positive associations of T-STAI with total carbohydrate intake (ß = 0.04; p < 0.04), complex carbohydrate intake (ß = 0.05; p < 0.02), and percentage energy from carbohydrates (ß = 0.01; p < 0.03), as well as a significant inverse association of T-STAI with percentage energy from fat (ß = -0.01; p < 0.05). As regards males, the only significant finding was an inverse association between T-STAI and percent of the mean daily energy from protein (fully-adjusted model: ß = -0.01; p = 0.05). CONCLUSION: This cross-sectional study found modest sex-specific associations between anxiety status and macronutrient intake among French non-diabetic adults. Prospective studies are needed to further elucidate the observed associations.

OBJECTIVES: Front-of-package nutrition labels are intended to easily convey to consumers comprehensible information about the nutritional composition of pre-packaged food and are thus a tool in the combat against the growing prevalence of nutrition-related disorders, such as obesity, type 2 diabetes, cardiovascular disease, and some types of cancer. The objective of the present narrative review was first to describe Nutri-Score and then to synthesize some of the international scientific evidence for its effectiveness. Guided by scientific data and collective expertise, France formally adopted labelling of pre-packaged food with the 5-colour Nutri-Score label in October 2017 and that move was later followed by Belgium, Spain, Germany, Switzerland, the Netherlands, and Luxembourg. METHODS: This article synthesizes evidence from several countries regarding the effectiveness of Nutri-Score and the associated individual-level diet quality index in terms of attitude/behaviour- and health-related outcomes. It also addresses criticism levied at the label. RESULTS: The effectiveness of Nutri-Score has been demonstrated in terms of consumer ability to correctly classify food according to its nutritional quality, the nutritional quality of actual and intended food purchases, and portion size choices. In addition, consumption of foods that are less favourably rated on the Nutri-Score scale has been prospectively associated with chronic disease risk (cancer, cardiovascular disease, metabolic syndrome, etc.). CONCLUSION: The adoption and implementation of a uniform front-of-package label such as the scientifically validated Nutri-Score on pre-packaged foods/beverages across Europe could be beneficial to consumers at the point of purchase and could help reduce the incidence of diet-related chronic diseases by means of improvement in diet quality.

BACKGROUND: The effectiveness of Front-of-Pack nutrition Labels (FoPLs) may be influenced by national context. In light of the ongoing efforts to harmonize FoPLs across Europe, this study aimed to compare the effectiveness of five FoPLs (Health Star Rating system, Multiple Traffic Lights, Nutri-Score, Reference Intakes, Warning symbols) on consumer understanding and food choice in 12 European countries. METHODS: In 2018-2019, for three food categories, approximately 1000 participants per country were asked to select which food they would prefer to purchase between three products with distinct nutritional quality profiles, and then to rank the products by nutritional quality. Participants (N = 12,391 in total) completed these tasks first with no FoPL and then, after randomization to one of the five FoPLs, with a FoPL on the food packages. Associations between FoPLs and change in (i) nutritional quality of food choices and (ii) ability to correctly rank the products by nutritional quality were assessed with logistic regression models adjusted for sociodemographic and lifestyle characteristics of participants, conducted overall and by country. FINDINGS: Compared with the Reference Intakes, the Nutri-Score (OR = 3.23[2.75-3.81]; p < 0.0001), followed by the Multiple Traffic Lights (OR = 1.68[1.42-1.98]; p < 0.0001), was the most effective FoPL in helping consumers identify the foods' nutritional quality, overall and in each of the 12 countries. Differences between FoPLs regarding food choice modifications were smaller, but the effect of the Nutri-Score seemed slightly higher in eliciting healthier food choices overall compared with the Reference Intakes, followed by the Warning symbols, the Multiple Traffic Lights and the Health Star Rating system. INTERPRETATION: In the context of FoPL harmonization in Europe, these findings from an online experiment provide insights into the Nutri-Score's effectiveness on European consumers.

OBJECTIVE: The objective of this cross-sectional study was to assess whether optimism is associated with body mass index (BMI), eating behavior and eating disorders (EDs) in a population-based study. METHOD: In 2016, a total of 32,805 participants aged ≥18 years from the NutriNet-Santé cohort completed the Life Orientation Test-Revised, assessing dispositional optimism. Height and weight were self-reported. Eating behavior was assessed with the revised 21-item Three-Factor Eating Questionnaire. Risk of EDs was evaluated with the Sick-Control-One-Fat-Food Questionnaire. Linear and Logistic regression was used to analyze the association between optimism, BMI categories, eating behavior and ED risk, controlling for sociodemographic, lifestyle and depressive symptom characteristics. RESULTS: Our sample was composed of 73.5% women, and the mean age was 55.39 ± 13.70 years. More optimistic participants were less likely to be underweight (OR = 0.82; 95% CI: 0.75, 0.89), or obese, particularly class III obese (BMI ≥40 kg/m2 ) (OR = 0.69; 95% CI: 0.56, 0.84) compared with less optimistic individuals. Optimism was negatively associated with cognitive restraint (ß = -.07; 95%CI: -0.08; -0.06), emotional eating (ß = -.17; 95% CI: -0.19, -0.16) and uncontrolled eating (ß = -.10; 95% CI: -0.11, -0.09). In addition, more optimistic participants had a lower risk of EDs (OR = 0.60; 95% CI: 0.56, 0.64). DISCUSSION: Our findings showed that optimism was associated with weight status, eating behavior and risk of EDs in both women and men. The causal structure of the underlying observed association remains unclear and should be further investigated.

A growing number of studies have explored overall health during ageing in a holistic manner by investigating multidimensional models of healthy ageing (HA). However, little attention has been given to the role of adherence to national nutrition guidelines in that context. This study aimed to investigate the prospective association between adherence to the French nutrition guidelines and HA. The authors analysed data from 21 407 participants of the NutriNet-Santé study with a median baseline age of 55·6 years (2009-2014) and initially free of major chronic diseases. HA was defined as not developing major chronic disease, no depressive symptoms, no function-limiting pain, independence in instrumental activities of daily living, good physical, cognitive and social functioning, as well as good self-perceived health. Adherence to guidelines of the French Nutrition and Health Programme (Programme National Nutrition Santé or PNNS) was measured via the PNNS Guideline Score (PNNS-GS), using baseline data from repeated 24-h dietary records and physical activity questionnaires. After a median follow-up of 5·7 years, 46·3 % of participants met our HA criteria. Robust-error-variance Poisson regression revealed that higher PNNS-GS scores, reflecting higher adherence to nutrition recommendations (including both diet and physical activity guidelines), were associated with a higher probability to age healthily (relative riskquartile 4 v. quartile 1 = 1·17 (95 % CI 1·12, 1·22)). Supplementary analyses revealed that this association may, to a small part, be mediated by weight status. The results suggest that high adherence to the French national nutrition recommendations may be linked to better overall health throughout ageing.

Circadian disruption has been classified as probably carcinogenic to humans by the World Health Organization's International Agency for Research on Cancer. The circadian clock is subject to environmental factors, particularly light exposure and food intake rhythms. However, the association between nutritional circadian behaviours and cancer is not well understood. We investigated the longitudinal associations between number of eating episodes, night-time fasting duration, time of first and last eating episodes, as well as nutritional quality of last eating episode, respectively, with breast and prostate cancer risks, the two main cancer locations in women and men respectively. This prospective study included 41,389 day-working adults in the French NutriNet-Santé cohort (2009-2016) who completed at least three 24 h dietary records during the first 2 years of follow-up. Multivariable Cox models were computed. 1,732 first primary incident cancer cases were diagnosed during the follow-up, among which 428 breast and 179 prostate cancers. After adjustment for covariates including sleep duration, late eaters (last eating episode after 9:30 pm) had an increased risk of breast (Hazard ratio [HR] = 1.48 [1.02-2.17], p = 0.03) and prostate (HR = 2.20 [1.28-3.78], p = 0.004) cancers. However, no association was observed between cancer risk and number of eating episodes, night-time fasting duration, time of first eating episode or macronutrient composition of the last eating episode. This large cohort study suggests that circadian perturbations resulting from late time of last food intake may be involved in carcinogenesis at different locations. Beyond nutritional quality of food intake, nutritional circadian regulation should be further investigated in the context of cancer prevention.

BACKGROUND: The association between obesity and migraine has been established; however, it is unclear whether it varies by perceived stress within each gender. METHODS: This cross-sectional study used data from the ongoing NutriNet-Santé e-cohort with enrollees from the general population. Anthropometric and migraine data were provided via self-report questionnaires (2013-2016). Migraine was defined using established criteria. Perceived stress was assessed with Cohen's Perceived Stress Scale-10. Associations were estimated via gender- and stress-stratified multivariable polytomous logistic regression models. RESULTS: Among 32,835 participants with complete data (75% women; mean age = 51.9 ± 13.8 years), 34% reported no headache, 44% non-migraine headache, and 22% migraine with or without aura during one's lifetime. In these groups, obesity was present in 8.6, 9.9, and 11.6%, respectively. Stress was a significant moderator of the obesity-migraine association only among women. The largest significant adjusted odds ratio (aOR) was found between obesity and migraine in women with high stress (aOR 1.61, 95% CI 1.35-1.91). CONCLUSIONS: We found support for gender- and stress-dependent associations between obesity and migraine using a large, heterogeneous adult sample. This underscores the need for evidence-based strategies for weight loss and stress reduction for female migraineurs.

PURPOSE: This study examines whether adherence to the Mediterranean Diet (MD) measured by several dietary indexes was associated with incident depressive symptoms in a large French cohort. METHODS: The study sample consisted of 3523 participants from the Supplémentation en Vitamines et Minéraux Antioxydants (SU.VI.MAX) cohort who had at least three dietary records at baseline during the first 2 years of follow-up (1994-1996), free of depression at the beginning of the study (1996-1997) and available Center for Epidemiologic Studies Depression Scale (CES-D) data at the end of follow-up (2007-2009). The rMED was computed. Incident depressive symptoms were defined by a CES-D score ≥17 for men and ≥23 for women in 2007-2009. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using multivariable logistic regression models. Several sensitivity analyses were performed. RESULTS: In the present study, 172 incident cases of depressive symptoms were identified during the follow-up (mean = 12.6 years). After adjustment for a wide range of potential confounders, adherence to the rMED score (continuous variable) was significantly associated with incident depressive symptoms in men (OR 0.91; 95% CI 0.83-0.99; p = 0.03), but not in women. Use of the Literature-Based Adherence Score to the Mediterranean Diet (LAMD) and the classic MD score (MDS) provide similar findings. CONCLUSIONS: In the current study, higher adherence to the Mediterranean Diet at midlife was associated with a lower risk of incident depressive symptoms, particularly in men, increasing scientific evidence for a beneficial role of Mediterranean Diet on health. Further investigations in particular among women are needed.
