Background: for preschool children aged four to five, parents play a key role in the adoption of a healthy lifestyle. Social representations are central to understanding the choice of health behaviours promoted by the parent in their child’s life. Objective: to describe the social representations of parents with respect to the weight and lifestyle of children aged four to five. Methods: in their descriptive qualitative study, two semi-structured interviews were conducted with a purposive sample of fourteen parents who had children aged four to five that were either of normal weight or overweight or obese, until data saturation was achieved. The collected data was analyzed using inductive analysis. Results: some parents view weight as a health issue while others consider a chubby appearance as normal for a child aged four to five. All participating parents view lifestyle as a demanding challenge. Conclusion: the results provide guidance for developing healthy lifestyle strategies that are consistent with parental obligations.
