Childhood obesity has been rising steadily over the past 40 years. In 2016, the World Health Organization (WHO) observed around 340 million overweight or obese children and adolescents worldwide, including one in five in France. The causes are complex, both individual (genetic, biological, behavioral) and collective (social, economic, cultural). Childhood obesity encourages the development of chronic diseases such as diabetes and hypertension, and can affect mental health. Without early treatment, the risk of obesity persisting into adulthood is high. In the Alpes-Maritimes region, the commune of Mouans-Sartoux has been promoting a local diet in line with PNNS-4 recommendations since 2011. We wish to study the impact of these actions on the health of Mouans children. We propose a preliminary observational study to assess the relationship between family adherence to PNNS recommendations and the prevalence of overweight and obesity in Mouans-Sartoux elementary school children.

To assess the association between the risk of overweight and/or obesity in children and family adherence to PNNS-4 recommendations.
Calculation of the odd-ratio (OR) between the risk of "overweight and/or obesity" in children (corresponding to a BMI z-score \> 1) and family adherence to PNNS recommendations estimated from the "PNNS-GS2" score using a univariate logistic regression model.
Time frame: 1 year
To assess the association between the risk of overweight and/or obesity in children and the importance of organic food in family dietary habits.
The "Organic and Local Food Consumption" questionnaire (18) is used to estimate household consumption of organic products. The score obtained from this questionnaire will be evaluated in a similar way to the "PNNS-GS2" score. We will study the prevalence of overweight and obesity according to the presence or absence of each listed risk factor belonging to the following categories: * Children's physical activity and sports * Favorable behaviors * Household socio-demographic data * Child's environment * Parents' lifestyle * Declarative medical data
Time frame: 1 year
Evaluate the influence of children's school canteen enrolment on family adherence to the National Health Nutrition Program 4 (PNNS-4) recommendations by PNNS-GS2) score
We will assess the impact of whether or not children are enrolled in the canteen by studying for each group the distribution of the National Health Nutrition Program - Guidelines Score 2 (PNNS-GS2) score; The "PNNS-GS2" score assesses families' adherence to the PNNS-4 recommendations, based on a list of items relating to eating habits. Responses are grouped into quartiles to form comparison groups. In this study, the score is assessed at family level.

Evaluate the influence of children's school canteen enrolment on family adherence to the National Health Nutrition Program 4 (PNNS-4) recommendations by "Organic and Local Food Consumption" score
We will assess the impact of whether or not children are enrolled in the canteen by studying for each group the distribution of the "Organic and Local Food Consumption" score. List of food groups 1. Fruit 2. Vegetables 3. Soy 4. Dairy products 5. Meat and fish 6. Eggs 7. Grains and pulses 8. Bread and cereals 9. Flour 10. Vegetable oils and condiments 11. Prepared dishes 12. Coffee/tea/tea tea 13. Sweet products 14. Food supplements 15. Other foods For each group, participants indicated their frequency of consumption * Organic: "Most of the time", "From time to time", "Never". * Locally produced: "Most of the time", "From time to time", "Never". Two scores are created: "organic food score" for organically sourced food, and "local food score" for locally produced food, awarding: * 2 points for "Most of the time * 1 point for "Once in a while * 0 points for "Never The two scores are added together to obtain the "organic and local food score".
Time frame: 1 year
Evaluate the influence of children's school canteen enrolment on family adherence to the National Health Nutrition Program 4 (PNNS-4) recommendations by the distribution of the z-score.
We will assess the impact of whether or not children are enrolled in the canteen by studying for each group the distribution of the z-score and the prevalence of overweight and obesity. In children, BMI is not a good representation of corpulence, as individual growth varies according to sex and age. We therefore use the BMI z-score (called "Z-score" in this study), which expresses the deviation of a child's BMI from the reference value according to sex and age. The Z-score can be used to classify children into several categories according to the following limits: * Extreme thinness * Thin * Normal build * Overweight * Obese
Time frame: 1 year
Evaluate the influence of children's school canteen enrolment on family adherence to the National Health Nutrition Program 4 (PNNS-4) recommendations by prevalence of risks factors.
We will assess the impact of whether or not children are enrolled in the canteen by studying for each group prevalence of risk factors studied.
Time frame: 1 year
Compare the observed proportion of mouansois children who are overweight or obese with data from the Alpes-Maritimes department's maternal and child protection service.
We will calculate the difference between the observed proportion of overweight or obese children in Mouans and that expected according to the data presented by the Protection Maternelle et Infantile des Alpes-Maritimes.
Time frame: 1 year
Collect hair samples from local children to build up a sample bank for future research into the presence of pesticides and endocrine disruptors.
We will be collecting hair samples from volunteer children in Mouans, in order to build up a sample bank in parallel with the study, with a view to future work on measuring the presence of endocrine disruptors / pesticides.
