Relationship between children's eating behavior (1-6 years) and body mass index: a cross-sectional study in French maternal-infant protection centers within the Parisian region

Background Early detection of obesity-promoting dietary behavior patterns improves the identification of at-risk families and the implementation of interventions. This is accomplished through the use of the Child Eating Behavior Questionnaire (CEBQ). No study has been conducted using the CEBQ in children followed in Essonne's Maternal-Infant Protection (PMI) centers. We investigated, in a cross-sectional design, the differences in children's eating behavior with PMI follow-up according to their weight status.Methods A questionnaire addressed to parents was collected in PMI centers. Multiple hierarchical regression analysis was used to investigate the predictability of the child's CEBQ on body mass index (BMI).Results From January to April 2022, 850 children were selected, from which 500 (aged 1-6 years) were included, and of whom 10.6% were obese. There was a significant positive association between 'Food Responsiveness', 'Enjoyment of Food' and BMI. In contrast, there was a significant negative association between 'Satiety Responsiveness', 'Slowness in Eating' and BMI. Besides, 'Food approach' and 'food avoidance' behaviors were positively and negatively related to BMI z-scores, respectively.Conclusion Due to significant differences in children's eating behavior according to their weight, it is needed to raise awareness among parents about their impact on them.
