Nutri-Bébé 2022 A French National Survey on Feeding Practice and Nutrient Intakes of Children Under 3 Years of Age

Infant's and young children's diet is a determining factor in their growth and development and may impact the occurrence of non-communicable diseases in the medium and long term. In this context, knowledge regarding the feeding practice and nutrients intake in children under 3 years of age is valuable, whether for the entire scientific and medical community or for the public authorities.

Aiming to help achieving this objective, the SFAE has carried out a national observational survey every 8 years since 1981. The analysis of these data over time makes it possible to evaluate the intakes of different nutrients, to note possible nutritional insufficiencies or excesses, potentially linked to bad eating habits. On these bases, this repeatable survey can alert health professionals and help refine public health nutrition policy in France. A new edition was launched between March 2022 and July 2022 by an official polling institute, IPSOS. The sample includes more than 1,200 children aged from 0.5 to 35 months, distributed in 11 age-groups of equal importance, and living in metropolitan France (excluding Corsica).

This is a cross-sectional observational survey.

IPSOS fulfills the following standards and industry requirements (ESOMAR professional code of conduct and standards, ISO 20252:2012 international standard for market, opinion and social research, French data protection act (loi "informatique et libertés "). IPSOS ensures to conduct the surveys in accordance with the regulation on personal data protection and that respondents' personal identity is withheld. The SFAE has undertaken with the "Commission Nationale de l'Informatique et des Libertés" (CNIL), the French data protection authority) to respect the MR-003 reference methodology and is authorized to set up the processing of data without prior authorization from the CNIL (declaration n° 2220501 of 2020/12/18).

Information on the children will be collected directly from the responding parents (primarily responsible for their child's diet). The collection of information will be carried out according to the following successive stages:

• recruitment of families according to the quota method, provided they are fluent in French language and can use a computer.
• To be included children should be born at term with a birth weight ≥ 2500 g and should have no intercurrent acute or chronic disease.
• Face-to-face interview at home by an investigator to collect informed consent of the parents, sociodemographic data, child weight and height as well as information on children's eating habits.
• Completion by the parent of an online consumption diary for a period of 3 non-consecutive days (2 weekdays and 1 weekend day, with at least one day of separation between each collection day).
• Self-questionnaire to be completed by the responding parent on the child's diet, context and physical activities.

The study conducted in 2022 is the sixth edition of the Nutri-Bébé survey.

Inclusion criteria

• Child aged 0.5 to 35 months
• Child whose responding parent, mainly responsible for his diet, agrees to complete the three stages of the survey (informed consent).
• Child whose responding parent accepts the collection of birth weight, and the most recent weight and height in the health booklet. If the weight measurement has not been performed recently, the responding parent agrees to measure the weight of their child during the first interview. In this case, the presence of the child will be necessary. A recent weight corresponds to a measurement in the 15 days preceding inclusion for children aged 0-6 months, in the month preceding inclusion for children aged 6-12 months and in the two months preceding inclusion for those over one year old.
• Child whose parents have been informed of the study orally and in writing, and have not objected to the participation of the child before its inclusion and to the collection of information concerning them.
• In the case of the spouse of the responding parent, different from the second parent and living in the same household, no opposition to the collection of data concerning him

Exclusion criteria

• Child with a chronic or intercurrent pathology (including food allergies)
• Child with a birth weight of less than 2.5 kg
• Child whose last weight measurement in the health record is not recent enough AND whose parent refuses to measure his weight
• Child having to take at least one meal at school during the 3 days of filling in the consumption diary
• Child cared for by the crèche or by a third party and whose person responsible for meals refuses to send all the information (qualitative and quantitative) to the responding parent so that he can complete the consumption diary
• Child whose sponsoring parent is under the age of 18, or is placed under guardianship or curatorship, or under legal protection
