RESUMEN

Some epidemiological studies have raised health concerns following the chronic exposure of pregnant women and children to pesticides in the domestic environment. In France very little is known about potential exposure to pesticides at home. An observational study called Pesti'home was carried out in continental France between July and November 2014. The residential use of pesticides was investigated and an inventory of pesticides and active ingredients used and stored at home was drawn up. Plant protection products, biocides, and human and animal external pest control products were listed during face-to-face interviews. A random sample of households including at least one adult (18-79 years old) was selected following a two-stage stratified random sampling method using the national census database. Within each household, an adult was appointed to answer survey questions. Data related to the interviewee's sociodemographic and housing characteristics, the reported use of pesticides at home, and a visual inventory of all stored pesticides were collected. Overall, 1507 households participated. The participation rate was between 36% and 57% according to the definition chosen. Over the previous 12 months, 75% of households declared that they had used at least one pesticide. Households who used and stored at least one product most frequently used an insecticide (84%). The active ingredients most frequently used by these households as insecticides were pyrethroids, namely tetramethrin and permethrin. The Pesti'home survey collected detailed data on the residential use of pesticides for risk assessment at national and European levels.

RESUMEN

PURPOSE: While the consumption of ultra-processed foods is steadily increasing, there is a growing interest in more sustainable diets that would include more plant protein. We aimed to study associations between the degree of food processing, patterns of protein intake, diet quality and cardiometabolic risk. METHODS: Using the NOVA classification, we assessed the proportion of energy from unprocessed/minimally processed foods (MPFp), processed foods (PFp) and ultra-processed foods (UPFp) in the diets of 1774 adults (18-79 years) from the latest cross-sectional French national survey (INCA3, 2014-2015). We studied the associations between MPFp, PFp and UPFp with protein intakes, diet quality (using the PANDiet scoring system, the global (PDI), healthful (hPDI) and unhealthful (uPDI) plant-based diet indices) and risk of cardiometabolic death (using the EpiDiet model). RESULTS: MPFp was positively associated with animal protein intake and plant protein diversity, whereas PFp was positively associated with plant protein intake and negatively with plant protein diversity. The PANDiet was positively associated with MPFp (ß = 0.14, P < 0.0001) but negatively with UPFp (ß = - 0.05, P < 0.0001). These associations were modified by adjustment for protein intakes and plant protein diversity. As estimated with comparative risk assessment modeling between extreme tertiles of intake, mortality from cardiometabolic diseases would be decreased with higher MPFp (e.g. by 31% for ischemic heart diseases) and increased with higher UPFp (by 42%) and PFp (by 11%). CONCLUSIONS: In the French population, in contrast with UPFp, higher MPFp was associated with higher animal protein intake, better plant protein diversity, higher diet quality and markedly lower cardiometabolic risk.

RESUMEN

BACKGROUND: There is a current trend in Western countries toward increasing the intake of plant protein. A higher plant-protein intake has been associated with nutritional and health benefits, but these may depend on the pattern of plant-protein sources. OBJECTIVE: We hypothesized that the diversity of plant foods could be important to nutrient adequacy when increasing plant-protein intake in the diet. METHODS: Using data on 1341 adults (aged 18-64 y) from a representative French national dietary survey conducted in 2014-2015 (the third Individual and National Study on Food Consumption Survey-INCA3), we studied the links between plant-protein intake, dietary diversity (using various dimensions), and nutrient adequacy [assessed using the PANDiet (Probability of Adequate Nutrient Intake) scoring system, comprising adequacy (AS) and moderation (MS) subscores]. We simulated substituting plant-protein foods for animal-protein foods using different models of plant-protein diversity. RESULTS: We found that overall diet quality was weakly associated with total and protein diversity and more strongly with plant-protein diversity. Plant-protein intake was inversely associated with animal-protein intake, and positively with the PANDiet and MS, but not with the AS. Plant-protein intake displayed little diversity, mostly taking the form of grains (61% of plant-protein intake), and this diversity was even less marked under a higher plant-protein intake. Finally, modeled substitutions showed that reducing animal-protein intake increased the MS (by 32%) in a similar manner whichever plant protein was used for substitution, whereas it decreased the AS (by 20%) unless using a highly diversified plant-protein mix. These simulated improvements in overall adequacy included marked decreases in adequacy regarding certain nutrients that are typically of animal origin. CONCLUSIONS: We conclude that in French adults the current pattern of plant-protein intake is hindering the nutritional benefits of a transition toward more plant protein, indicating that the consumption of plant-protein-based foods other than refined grains should be encouraged.

RESUMEN

OBJECTIVE: Assessing dietary exposure or nutrient intakes requires detailed dietary data. These data are collected in France by the cross-sectional Individual and National Studies on Food Consumption (INCA). In 2014-2015, the third survey (INCA3) was launched in the framework of the European harmonization process which introduced major methodological changes. The present paper describes the design of the INCA3 survey, its participation rate and the quality of its dietary data, and discusses the lessons learned from the methodological adaptations. DESIGN: Two representative samples of adults (18-79 years old) and children (0-17 years old) living in mainland France were selected following a three-stage stratified random sampling method using the national census database. SETTING: Food consumption was collected through three non-consecutive 24 h recalls (15-79 years old) or records (0-14 years old), supplemented by an FFQ. Information on food supplement use, eating habits, physical activity and sedentary behaviours, health status and sociodemographic characteristics were gathered by questionnaires. Height and body weight were measured.ParticipantsIn total, 4114 individuals (2121 adults, 1993 children) completed the whole protocol. RESULTS: Participation rate was 41·5% for adults and 49·8% for children. Mean energy intake was estimated as 8795 kJ/d (2102 kcal/d) in adults and 7222 kJ/d (1726 kcal/d) in children and the rate of energy intake under-reporters was 17·8 and 13·9%, respectively. CONCLUSIONS: Following the European guidelines, the INCA3 survey collected detailed dietary data useful for food-related and nutritional risk assessments at national and European level. The impact of the methodological changes on the participation rate should be further studied.

RESUMEN

The French Nutrition and Health Survey (ENNS) reported higher biomarker levels of exposure to pyrethroids than those observed in North American and German biomonitoring studies. The authors therefore investigated aggregate exposure to permethrin as an initial case study because this compound is one of the most widely-used pyrethroid insecticides. We assessed several contamination sources-such as indoor and outdoor air, settled dust and diet-and several pathways, including oral, inhalation and dermal routes. We used permethrin exposure level estimations (computed from ENNS data) and a PBPK model calibrated with human kinetic data (from 6 individuals) to simulate an internal dose of cis- and trans-3-(2,2 dichlorovinyl)-2,2-dimethyl-(1-cyclopropane) carboxylic acid (cis- or trans-DCCA) in a population of 219 individuals. The urinary concentrations of cis- and trans -DCCA predicted by the PBPK model according to three permethrin exposure scenarios ("lower", "intermediate", and "upper"), were compared to the urinary levels measured in the ENNS study. The ENNS levels were between the levels simulated according to permethrin exposure scenarios "lower" and "intermediate". The "upper" scenario led to an overestimation of the predicted urinary concentration levels of cis - and trans -DCCA compared to those measured in the ENNS study. The most realistic scenario was the "lower" one (permethrin concentration of left-censored data considered as 0). Using PBPK modeling, we estimated the contribution of each pathway and source to the internal dose. The main route of permethrin exposure was oral (98%), diet being the major source (87%) followed by dust (11%) then the dermal route (1.5%) and finally inhalation (0.5%).

RESUMEN

OBJECTIVE: The present research aimed to study the multidimensionality of the link between dietary intake and socio-economic position (SEP) in a representative sample of French children and adolescents, using a variety of SEP indicators. DESIGN: Data from the second French national food consumption survey (INCA2) were used. Information on food consumption was collected using a 7d food record and SEP data (occupation, education, income, household wealth indices) using questionnaires. Multivariable linear regression analyses were performed separately in children and adolescents to assess the relationships between dietary components (food groups and macronutrients) and each dimension of SEP. SETTING: The INCA2 survey, France. SUBJECTS: A representative sample of French children (3-10 years of age; n 574) and adolescents (11-17 years of age; n 881). RESULTS: Compared with children from a higher SEP, those from a lower SEP had lower intakes of fruit and vegetables, yoghurts and confectionery and higher intakes of starchy foods, meat, milk, sugar-sweetened beverages and pizzas/sandwiches. Similar results were observed in adolescents for fruit and vegetables, yoghurts and sugar-sweetened beverages. Adolescents also had lower intakes of cakes/pastries and higher intakes of processed meat and dairy desserts. Neither energy nor protein intake was associated with SEP. Adolescents from a lower SEP had higher carbohydrate and lower lipid intakes. Overall, these findings were consistent across the various dimensions of SEP, but the gradient was steeper depending on the caregiver's educational level. CONCLUSIONS: This research highlights the need for specific messages to help poorly educated families adopt good eating habits.

RESUMEN

OBJECTIVE: Recently, school meal composition regulations have been implemented in France in order to improve the nutritional status of children. The present study investigated the link between school lunch attendance and the food intakes of schoolchildren aged 3-17 years. DESIGN: Second French cross-sectional dietary survey (2006-2007). Eating frequencies were assessed for twenty-four food groups with a 7 d food record. Eating locations were recorded for main meals. Food group intakes at weekday lunches were compared for the school canteen and for other locations. The children's overall dietary intake was compared based on school lunch attendance. SETTING: Mainland France. SUBJECTS: Schoolchildren aged 3-17 years (n 1068). RESULTS: Lunchtime food intake differed between the school canteen and other locations. Some intakes at school canteens were more in accordance with the regulations (more fruit and vegetables, fish and dairy products, and less sandwiches, soft drinks, chocolate and confectionery), whereas others highlighted needs for improvement (more sweet biscuits and pastries, ice cream and dairy desserts, pizzas and salty pastries). Many of these differences were also observed in the children's overall diet: children regularly attending school lunches ate more mashed fruit, fish and sweet biscuits or pastries, and less sandwiches and soft drinks. The link between school lunch attendance and overall diet was less pronounced in secondary-school children. CONCLUSIONS: School canteen attendance is associated with both potentially beneficial and deleterious differences in the lunchtime and overall diets of French children. These findings are important to consider when setting national regulations for school meal composition.

RESUMEN

The 2nd French Total Diet Study demonstrated that 0.6% of adults and 14.9% of children exceeded the tolerable weekly intake set by EFSA. The overexposure of several consumers (adults and children) can be partially due to the high consumption of bread and dried bread products, of bivalve mollusks and of potatoes. Except for mollusks, these foods are the main contributors identified for the general population. On this basis, the French agency for food, environmental and occupational health and safety (ANSES) assessed whether a decrease of the European maximum limits in foodstuffs could significantly reduce the level of exposure of French consumers. Applying ML set at P90 of the main contributors would neither significantly reduce exposure levels to cadmium for the general population, nor the percentage of subjects exceeding the TWI. To reduce background consumer exposure to cadmium, actions to be taken include efforts on sources that are at the origin of the soil contamination and the efficacy of consumption recommendations.

RESUMEN

Energy intake under-reporting (UR) is a concern in nutritional epidemiological studies, as it may distort the relationships between dietary habits and health. Although UR is known to be associated with certain characteristics, few studies have investigated them in France. Therefore, the goal of the present study was to assess the prevalence and characteristics of UR in French adults. UR was defined according to Goldberg's classification. A sample of 1567 adults was drawn from the nationally representative French dietary survey (Individuelle Nationale des Consommations Alimentaires 2 2006-7). Food intake (7 d record), dietary habits, socio-economic status, region of residence, sedentary behaviour and weight perception variables were assessed. Multivariate logistic regression was used to investigate the associations between UR and a number of covariates. The overall prevalence of UR was 22.5%, similar in men and women. In both sexes, UR was positively associated with overweight and protein intake and inversely associated with age. In women, UR was associated with eating lunch in the office, poor perception of diet quality and sedentary behaviour and was inversely associated with educational level, residence in the Paris region, cereal product intake and eating lunch in a friend's or family member's home. In men, UR was positively associated with a history of slimming and inversely associated with dairy product intake and eating lunch at a staff canteen. In conclusion, UR is prevalent in French adults and is associated with several different characteristics. It is important to take account of UR when investigating diet-disease associations in adults.

RESUMEN

To improve the dietary offering in schools, the French authorities published recommendations on nutrition in 1999, which were then revised in 2007. The aim of the present study was to assess the nutritional offering in secondary school meals and the extent to which the recommendations promote balanced nutritional offerings. In 2005, a national survey was conducted on a representative sample of secondary schools, either administrated by the Ministry of Education (ES) or the Ministry of Agriculture (AS). Information on school-catering organisation and twenty consecutive meals was collected from each of the 707 secondary schools surveyed. Nutritional composition was estimated according to the French food composition database. Univariate and multivariate analyses were used to investigate the impact of food-group frequency guidelines (FFG) on nutritional offering. It was found that 15 and 26 % of ES and AS schools, respectively, had high compliance with the FFG, at lunch. Macronutrient content was unbalanced in ES school lunches in which 42·8 % lipids, 21·5 % proteins and 35·7 % carbohydrates contributed to the energy. Nevertheless, proper offerings in Fe, Ca and vitamin C content were observed. In addition, a lower offering in lipids and a higher offering in proteins, Ca, vitamin C and Fe were found when the FFG were applied (P < 0·001). Similar results were found for AS schools. This paper confirms the effectiveness of FFG in providing nutritionally balanced school meals. However, others measures such as nutrition promotion and actions to improve children's food habits have to be introduced to make the recommendations more effective and easier to understand.

RESUMEN

Studies using 24 h urine collections need to incorporate ways to validate the completeness of the urine samples. Models to predict urinary creatinine excretion (UCE) have been developed for this purpose; however, information on their usefulness to identify incomplete urine collections is limited. We aimed to develop a model for predicting UCE and to assess the performance of a creatinine index using para-aminobenzoic acid (PABA) as a reference. Data were taken from the European Food Consumption Validation study comprising two non-consecutive 24 h urine collections from 600 subjects in five European countries. Data from one collection were used to build a multiple linear regression model to predict UCE, and data from the other collection were used for performance testing of a creatinine index-based strategy to identify incomplete collections. Multiple linear regression (n 458) of UCE showed a significant positive association for body weight (ß = 0·07), the interaction term sex × weight (ß = 0·09, reference women) and protein intake (ß = 0·02). A significant negative association was found for age (ß = -0·09) and sex (ß = -3·14, reference women). An index of observed-to-predicted creatinine resulted in a sensitivity to identify incomplete collections of 0·06 (95 % CI 0·01, 0·20) and 0·11 (95 % CI 0·03, 0·22) in men and women, respectively. Specificity was 0·97 (95 % CI 0·97, 0·98) in men and 0·98 (95 % CI 0·98, 0·99) in women. The present study shows that UCE can be predicted from weight, age and sex. However, the results revealed that a creatinine index based on these predictions is not sufficiently sensitive to exclude incomplete 24 h urine collections.

RESUMEN

Chlordecone is an organochlorine insecticide used in the French West Indies until 1993. Toddlers are expected to be differently exposed than older children and adults. The dietary exposure to chlordecone of 18-month-old Guadeloupian toddlers was assessed through different scenarios depending on whether the subjects live on a soil-contaminated place or not and on their supply habits. Food contamination data came from the RESO study performed in 2005-2006. Consumption data derived from a dietary survey conducted in 2005-2008. Results were compared to those of other age groups. Chronic dietary exposures to chlordecone were estimated in a range of 0.018-0.051 µg/kg bw/day (P95: 0.044-0.096) for toddlers living in a non contaminated area and between 0.045-0.078 µg/kg bw/day (P95: 0.110-0.144) for toddlers living in a contaminated area. The probability of exceeding the chronic health-based value of 0.5 µg/kg bw/day was null. These results suggest that 18-month-old toddlers are less exposed than groups aged over 3 years old. This can be explained by their consumption pattern mostly based on milk and fruits, which are not highly contaminated by chlordecone. The acute health-based value of 10 µg/kg bw/day could be exceeded when consuming of highly contaminated taros, showing the importance of regulatory maximum limit.

RESUMEN

Estimating usual food intake distributions from short-term quantitative measurements is critical when occasionally or rarely eaten food groups are considered. To overcome this challenge by statistical modeling, the Multiple Source Method (MSM) was developed in 2006. The MSM provides usual food intake distributions from individual short-term estimates by combining the probability and the amount of consumption with incorporation of covariates into the modeling part. Habitual consumption frequency information may be used in 2 ways: first, to distinguish true nonconsumers from occasional nonconsumers in short-term measurements and second, as a covariate in the statistical model. The MSM is therefore able to calculate estimates for occasional nonconsumers. External information on the proportion of nonconsumers of a food can also be handled by the MSM. As a proof-of-concept, we applied the MSM to a data set from the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam Calibration Study (2004) comprising 393 participants who completed two 24-h dietary recalls and one FFQ. Usual intake distributions were estimated for 38 food groups with a proportion of nonconsumers > 70% in the 24-h dietary recalls. The intake estimates derived by the MSM corresponded with the observed values such as the group mean. This study shows that the MSM is a useful and applicable statistical technique to estimate usual food intake distributions, if at least 2 repeated measurements per participant are available, even for food groups with a sizeable percentage of nonconsumers.

RESUMEN

OBJECTIVE: To assess school canteen attendance in a French nationally representative sample of children and to analyse its association with the socio-economic and demographic characteristics of the children and their families. DESIGN: Data from the second French national cross-sectional food consumption survey (INCA2), performed in 2006-2007, were used. Information on usual weekly school canteen attendance was collected through a self-reported questionnaire, and demographic and socio-economic variables through a face-to-face questionnaire. The associations between school canteen attendance and the socio-economic and demographic variables were investigated by multivariate logistic regression analyses. SETTING: The INCA2 sample was representative of the children aged 3-17 years in France. SUBJECT: Analysis was performed on 1413 schoolchildren who completed the school canteen attendance questions. RESULTS: Some 65·6 % of schoolchildren aged 3-17 years had school lunch at least once weekly. This rate of attendance was positively correlated with age. Whatever the school level, school canteen attendance was positively associated with the educational level of the caregiver/parent. In pre- and elementary-school children, enrolment at the school canteen was also higher when the caregiver/parent worked, or in single-parent families. In secondary-school children, school lunch participation decreased with children living in more densely populated areas and increased with the level of the household's living standards. CONCLUSIONS: School canteen attendance was positively associated with children's socio-economic background. This could reduce the effectiveness of the forthcoming school meal composition regulations designed to improve the diet of children from deprived backgrounds, who are more likely to have unhealthy food habits.

RESUMEN

The levels of 20 essential or toxic trace elements in 159 fish, other seafood and seafood products on the French coastal market collected between January and April 2005 were measured by ICP-MS. The concentration ranges (mg/kg of fresh mass) for the elements determined were compared with previous studies. The contents of Co, Cu, Fe, Li, Mn, Se, Zn and Pb found in fish are close to or often lower than previous studies. For other seafood, comparison is difficult due to the lack of data on a more global scale. However, it should be noted that the contents of Ag were found considerably higher in this study.

RESUMEN

The objectives of the present study were to assess the intake of different food groups in French children aged 3-17 years (n 1455), and to analyse trends since a dietary survey undertaken 8 years ago. Dietary intake was evaluated using data from the 2006-7 cross-sectional INCA2 national dietary survey (étude Individuelle Nationale sur les Consommations Alimentaires), based on a 7 d food record. Dietary intake (percentage of subjects consuming the food group and amount eaten) was assessed for thirty-nine food categories. We observed variations in food consumption by age, sex, North-South regional gradient, seasonal period and educational level of the responding parent. Trends in dietary intake between 1999 and 2007 were determined by comparing the INCA1 (n 1126) and the INCA2 surveys. Both surveys had been carried out using the same methodology. The findings showed a decrease in energy intake in children aged 3-14 years, due to a reduction in the consumption of foods of animal origin and sweetened products. In adolescents aged 15-17 years, energy intake remained rather stable; during this 8-year period, the consumption of meat decreased, whereas the consumption of savoury snacks such as sandwiches and hamburgers significantly increased. These trends occurred during a time of growing concern about overweight and the associated co-morbidities in France. A number of public health measures were implemented over this period to improve dietary habits and physical activity patterns in children and adults. The periodic monitoring of dietary patterns through the INCA surveys is an essential part of the surveillance network in France.

RESUMEN

Two independent cross-sectional dietary surveys (the Individual and National Food Consumption Surveys, INCA), performed in 1998-99 (INCA1) and in 2006-07 (INCA2) on nationally representative samples of French people, were used to analyse trends in the dietary habits and nutritional intake of French adults. Food consumption was recorded through 7-d dietary records, and nutritional intakes were assessed using the French food composition database. After exclusion of under-reporters, analyses were performed on 3267 adults, aged 18-79 years: 1345 from INCA1 and 1922 from INCA2. The trends highlighted over the 8-year period showed a decrease in consumption of dairy products, meat, bread, potatoes, pastries/croissant-like pastries/cakes/biscuits and sugar/confectionery. In contrast, the consumption of fruits and vegetables, rice, ice cream and chocolate increased. Other food groups, like fish and snacking foods, remained stable. Food choices were mostly age specific. These age differences remained consistent over the years and underlined two opposite dietary trends: a 'traditional' one mainly followed by the elderly, and a 'snacking and convenience' one mainly adopted by young adults. The overall trends in food consumption did not influence the mean energy intake, but did slightly modify the contribution of each macronutrient to energy intake. These repeated surveys highlighted the fact that trends in French food habits have moved towards an average European diet at the crossroads between Mediterranean and Northern diets, and that food consumption changes impacted, to a lesser extent, nutritional intake.

RESUMEN

Different European institutions have developed mathematical models to propose maximum safe levels either for fortified foods or for dietary supplements. The objective of the present study was to compare and check the safety of these different maximum safe levels (MSL) by using a probabilistic risk assessment approach. The potential maximum nutritional intakes were estimated by taking into account all sources of intakes (base diet, fortified foods and dietary supplements) and compared with the tolerable upper intake levels for vitamins and minerals. This approach simulated the consequences of both food fortification and supplementation in terms of food safety. Different scenarios were tested. They are the result of the combination of several MSL obtained using the previous models. The study was based on the second French Individual and National Study on Food Consumption performed in 2006-7, matched with the French food nutritional composition database. The analyses were based on a sample of 1918 adults aged 18-79 years. Some MSL in fortified foods and dietary supplements obtained independently were protective enough, although some others could lead to nutritional intakes above the tolerable upper intake levels. The simulation showed that it is crucial to consider the inter-individual variability of fortified food intakes when setting MSL for foods and supplements. The risk assessment approach developed here by integrating the MSL for fortified foods and dietary supplements is useful for ensuring consumer protection. It may be subsequently used to test any other MSL for vitamins and minerals proposed in the future.

RESUMEN

Food based dietary guidelines (FBDGs) are developed to promote appropriate nutrients intake. However, FBDGs may trigger higher exposure to some food chemical contaminants while recommending the consumption of specific food groups that are more contaminated than others. In some cases, the balance between benefits and risks is difficult to achieve. In the present article, we describe the long-term impact of some FBDGs on the exposure to food contaminants. Two examples of bioaccumulative substances were studied: cadmium and PCBs. To this aim, lifetime dietary exposure trajectories were simulated for two populations: the first representing the general French population, the second generated using virtual individuals following national FBDGs during their entire life. Exposure trajectories were then converted into lifetime cadmium and PCB internal concentrations using physiologically based toxicokinetic models. Finally, trajectories were compared with reference values to assess the health risk related to dietary exposures to cadmium and PCBs, for both simulated populations. This work highlights that FBDGs may have a major impact on PCB dietary exposures and lead to significantly higher PCB plasma concentrations than those observed in the general population. In contrast, cadmium exposure is only slightly impacted when FBDGs are followed. This underscores the relevance of taking into account lifetime exposures when establishing FBDGs.
