[Schools meals in French secondary state schools: compliance to national recommendations and schools catering patterns]. / La restauration scolaire dans les établissements publics français du second degré : respect des recommandations nationales et profils d'établissements.

BACKGROUND: Recent reports on the lack of nutritional quality of meals served in schools have led public authorities to draft, in 1999, recommendations for restoring a balanced food supply. Following the survey carried out by the French food safety Agency in 2005-2006, which highlighted gaps in the implementation of these recommendations, a law passed in July 2010 plans to make these recommendations mandatory, as their 2007 revised version. Thus, the objective of this study was to assess initial school compliance with regard to this last revised version of the recommendations and to identify school patterns through their catering management and implication in a dietary project. METHODS: Seven hundred and seven secondary state schools were questioned (570 were administrated by the Ministry of Education and 137 by the Ministry of Agriculture) on their catering practices. Twenty consecutive menus from each school were also analyzed with a specific coding system to establish its nutritional composition for comparison with the 2007 recommendations. RESULTS: On average, schools complied with half of the recommendations. Good compliance was observed with the 2007 recommendations concerning fried products, starchy foods, fruits, and dairy products whereas very few schools were in compliance with recommendations concerning fish, cheeses and sweetened desserts containing less than 15 % fat and more than 20 g of sugar per portion. Furthermore, compliance with recommendations was significantly better for lunch meals, and even better for agricultural establishments. A 5-component meal was also associated with greater compliance with the recommendations. In addition, four school patterns were identified based on catering management practices. The first two categories of establishments had knowledge of the recommendations but exhibited different levels of application. The last two types of establishments had no knowledge of the recommendations and differed in their catering management practices. CONCLUSION: Compliance with recommendations was contrasted, with high adequacy for some guidelines and low for others. Nevertheless, application of the current guidelines and real implication of the school in a dietary project did improve the dietary offer in such schools.

Food and nutrient intake outside the home of 629 French people of fifteen years and over.

OBJECTIVE: This study was conducted to assess nutrient intake outside the home of 629 people representative of the French population. SUBJECTS: The study population consisted of 629 people aged 15 years and over. They were recruited in a randomized way with two levels (town and household). METHOD: Food intake outside the home was assessed by self-completed estimated record for 7 d. Individuals referred to photographs to estimate portions. Nutrient intake has been calculated for energy, protein, carbohydrate, fat and some minerals (calcium, phosphorus, magnesium, iron). RESULTS: Lunches and dinners eaten out are on average too rich in protein (20% of the energy), too high in fat (40-43% of the energy) and do not contain enough carbohydrate. The percentage of energy from sugars varies between 11% for lunch and 30% for breakfast. Mean intake of nutrients by beverages drunk outside the home decrease with the age of consumers. CONCLUSION: This study shows that foods and drinks consumed outside the home in France are on average too rich in fat and protein.

Core food of the French food supply: second Total Diet Study.

As first described in the 1980s, the core food intake model allows a precise assessment of dietary nutrient intake and dietary exposure to contaminants insofar as it reflects the eating habits of a target population and covers the most important foods in terms of consumption, selected nutrient and contaminant contribution. This model has been used to set up the sampling strategy of the second French Total Diet Study (TDS) with the aim of obtaining a realistic panorama of nutrient intakes and contaminant exposure for the whole population, useful for quantitative risk assessment. Data on consumption trends and eating habits from the second French individual food consumption survey (INCA2) as well as data from a 2004 purchase panel of French households (SECODIP) were used to identify the core foods to be sampled. A total of 116 core foods on a national scale and 70 core foods on a regional scale were selected according to (1) the consumption data for adults and children, (2) their consumer rates, and (3) their high contribution to exposure to one or more contaminants of interest. Foods were collected in eight French regions (36 cities) and prepared 'as consumed' to be analysed for their nutritional composition and contamination levels. A total of 20 280 different food products were purchased to make up the 1352 composite samples of core foods to be analysed for additives, environmental contaminants, pesticide residues, trace elements and minerals, mycotoxins and acrylamide. The establishment of such a sampling plan is essential for effective, high-quality monitoring of dietary exposure from a public health point of view.

Trends in child overweight rates and energy intake in France from 1999 to 2007: relationships with socioeconomic status.

Our objectives were (i) to assess the current prevalence of childhood overweight (including obesity) (OWOB) in France and its relationship with comprehensive socioeconomic status (SES) indicators and (ii) to examine trends in OWOB prevalence and changes in energy intake (EI) and sedentary behavior (SED) based on the previous INCA 1 (Individuelle Nationale des Consommations Alimentaires) data (1998-1999). A representative sample of children aged 3-14 (n = 1,030) was taken from the 2006-2007 cross-sectional INCA 2 food consumption survey. Weight and height were measured. The prevalence of OWOB was estimated according to the IOTF (International Obesity Task Force) definition. Average daily EI was evaluated using a 7-day food record. SED (screen time) and SES were reported by answering questionnaires. SES indicators included the occupation and level of education of the head of the household (HH), and variables describing household wealth. Composite indices of SES were computed by correspondence analysis, and relationships with OWOB were explored by logistic regression analysis. In total, 14.5% (95% CI: 12.1-17.0) of the children were OWOB. All SES indicators were inversely correlated to OWOB. Average EI was equal to 1,739 kcal/day. Daily, children spent 113.5 min watching television, and 38.5 min playing video games or using a computer. Compared to the INCA 1 study, OWOB prevalence was not significantly different, EI was lower, and SED was higher. These trends were the same across all occupational categories of heads of household. Although overall rates of childhood OWOB are currently stabilizing, no change was observed in the strong inverse socioeconomic gradient of OWOB between the two studies.
