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. 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. The INCA2 survey, France. A representative sample of French children (3–10 years of age; n 574) and adolescents (11–17 years of age; n 881). 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. This research highlights the need for specific messages to help poorly educated families adopt good eating habits.
