"The big win was that we actually cooked"- a qualitative interview study about the parental experience of Family Meals on Prescription for children living with obesity.

Purpose: The aim was to evaluate the parental experiences of participating in the randomized controlled trial "Family Meals on Prescription" for childhood obesity. The intervention consisted of a weekly prepacked grocery bag with recipes to cover five evening meals for the whole family.

Methods: Parental, semi-structed interviews were performed with at least one parent of the participating families. Inclusion criteria was that the family had actively participated in the intervention. The interview questions were formulated to explore the experiences, opinions and attitudes of the parents regarding the intervention. The interviews were transcribed and thematically analysed using both an inductive and deductive approach.

Results: Parents (six mothers and five fathers) from ten families were interviewed. The thematic analysis identified that the intervention reduced stress and was supportive regarding meal planning. The parents described an increased knowledge concerning food and cooking in the whole family and changes in meal behaviours such as more regular meals, trying new food and consuming more vegetables. Negative experience concerning the portion size being too large making it hard to maintain boundaries were also highlighted.

Conclusion: Parents described that the intervention with a subsidized prepacked grocery bag supported them in adapting more positive behaviours related to family meals through decreased stress levels and including the children in the daily cooking in an encouraging way. This method has the potential to help this group by directly engaging the whole families in new behaviours and enhancing family cohesion.
