Socio-ecological correlates of children's diet in the first 2 years of life: influence of socio-economic position and migration background in a French birth cohort.
Observational study in Public health nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveStrong social inequalities exist in chronic diseases related to diet and lifestyle. However, few studies have comprehensively examined the social determinants of children's diet at the family level, including paternal characteristics and migration background. This study aimed to assess the associations between family-based socio-ecological factors and children's dietary patterns (DP) during the first 2 years of life.
designThis longitudinal observational study applied a socio-ecological model to explore associations with children's DP. We conducted multivariable linear regression analyses with DP - identified via principal component analysis - as outcomes, sequentially adjusting for maternal factors: immigrant status, education, older children in the household, single motherhood and age (block 1); occupation (block 2) and household income (block 3). Similar analyses were performed with paternal characteristics.
settingNationwide French ELFE birth cohort.
participantsWe used data from an FFQ completed by parents of 12 696 2-year-old children.
resultsChildren born to mothers with a low socio-economic position (low education level; manual worker, unemployed or student or in the lowest household income quintile), with previous children, or who were living as a single parent had low scores on a DP defined as '
conclusionsEarly-life dietary inequalities are shaped by family-level social determinants, emphasising the need for early nutritional interventions tailored to disadvantaged families, particularly those with a migration background, low socio-economic status or single parenthood.
