The Nutri-Bébé 2013 survey is an observational cross-sectional study aiming to update food consumption, practices and nutrient intakes in children under 3 years of age in metropolitan France.

Nutri-Bébé 2013 is the 5th edition of a survey conducted every 8 years since 1981 by the SFAE. The Nutri-Bébé 2013 survey is an observational cross-sectional study conducted in children living in France aged 15 days to 35 months by an official polling institute, the TNS Sofres according to the guidelines laid down in the Declaration of Helsinki. TNS Sofres 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 "). TNS Sofres ensures to conduct the surveys in accordance with the regulation on personal data protection and that respondents' personal identity is withheld. Moreover TNS Sofres appointed a data protection officer, the "Correspondant Informatique et Libertés", who is the point of contact between the "Commission Nationale de l'Informatique et des Libertés" (CNIL), the French data protection authority) and the company. The company is thus exempted, of the notification process to the CNIL. Given the type of survey conducted, namely a survey of consumption, and the characteristics developed above, the study does not require any opinion of the ethics committee.

The survey includes a section on eating behaviours and a section on food consumption.

After giving their informed consent, parents had to record the food consumption during 3 non-consecutive days (2 week days and one weekend day)framed by two face-to-face interviews,. A second visit occurred seven days later to verify and complete the diary if necessary, and conduct a face-to-face interview with the mother about eating habits over the survey period. Both interviews were recorded using CAPI® software (Computer Assisted Personal Interviews, http://www.soft-concept.com). During this visit, the child was weighed (naked, with a clean diaper or underwear) using a Tefal PREMISS PP1000VO scale with a precision of 100 g.

The child's food consumption diary was completed between the two visits of the TNS Sofres investigator. The person in charge of the child was trained to qualitatively and quantitatively report all liquid and solid foods consumed and all drinks, by specifying the exact name of the product, its potential trademark or whether it was "homemade". The type of water consumed was noted as being either "bottled" or "tap". The type (breakfast, morning snack, lunch, afternoon snack, dinner, nocturnal food intake) and timing of food consumption were collected. If applicable, vitamin, mineral or medicine supplements were noted. During the second visit the investigator reviewed thoroughly the record with the caregiver and checked the way of reporting the quantities as well as the interpretation of the photographic tool kit in order to be as close as possible to reality.

Inclusion Criteria:

• informed parental consent to participate in the study,
• absence of intercurrent or chronic disease
• birth weight above 2.5 kg

Exclusion Criteria:

• Non compliance withe the study protocol
• For outcome 3 analysis (intakes), reported weight inconsistent with the child's age (> or <3 SD)

The present survey is based on a randomly selected sample with socio-demographic characteristics similar to the general population living in mainland France (i.e. excluding Corsica, overseas departments, regions, and communities, and New Caledonia). A quota sampling method was used: sampling wastratified by residential area, size of the urban agglomeration, infant gender, mother's professional activity, occupational and socio-occupational status and adjusted for these different characteristics. This stratification was based on the population characteristics of the 2002 census of the National Institute for Statistics and Economic Research (INSEE, Institut National de la Statistique et des Etudes Economiques).

To be shared is the global report of results on each items (food practices, food consumption, nutrients intakes), according to age groups.
