Abstract The aims of the present study are to assess the impact of a pleasure-oriented intervention on the nutritional quality of midafternoon snacks chosen by mother-child dyads and to evaluate the evolution of the relationship between the liking and perceived healthiness of the food items offered for the snack choices. Data were collected at two laboratory sessions (T1 and T2), during which children and mothers were separately asked to choose two food items (among 10) for a midafternoon snack, first for themselves and then for the other dyad member. Participants also rated their liking and perceived healthiness of the 10 food items. After T1, dyads were randomly assigned to an experimental group (N = 94) with an in-home pleasure-oriented intervention to stimulate the pleasure of consuming healthy foods or to a control group (N = 93). Our study shows the lack of a significant effect of the intervention on the nutritional quality of snacks chosen at T2. However, for the children in the experimental group, the relationship between liking and perceived healthiness which was not significant at T1 (τmedian = −0.05, P = 0.56) became significant and positive at T2 (τmedian = 0.13, P = 0.002). Moreover, this increase of the relationship in T2 was significantly higher for the experimental group compared to the control group (P = 0.05). For mothers, the existing relationship between liking and perceived healthiness at T1 (τmedian = 0.27, P

以愉悦为导向的干预对午后零食营养质量的影响以及对母子二人对食物喜好和感知健康之间关系的影响

摘要 本研究的目的是评估以愉悦为导向的干预对母子二人选择的午间零食营养质量的影响，并评估所提供食品的喜好和感知健康之间关系的演变。对于小吃选择。在两次实验室会议（T1 和 T2）中收集数据，在此期间，儿童和母亲分别被要求选择两种食物（从 10 种中）作为午后小吃，首先是为自己，然后是为其他成员。参与者还评价了他们对 10 种食物的喜好和感知的健康程度。在 T1 之后，二人组被随机分配到一个实验组（N = 94），进行以家庭愉悦为导向的干预，以刺激食用健康食品的愉悦感，或者被分配到一个对照组（N = 93）。我们的研究表明，干预对 T2 时选择的零食的营养质量没有显着影响。然而，对于实验组的孩子，喜欢和感知健康之间的关系在 T1 时不显着（τ中值 = -0.05，P = 0.56）在 T2 时变得显着且为正（τ中值 = 0.13，P = 0.002）。此外，与对照组相比，实验组的这种 T2 关系的增加显着更高（P = 0.05）。对于母亲，T1 时喜好和感知健康之间的现有关系（τ中值 = 0.27，P 喜好和感知健康之间的关系在 T1 时不显着（τ中值 = -0.05，P = 0.56）在 T2 时变得显着且为正（τ中值 = 0.13，P = 0.002）。此外，与对照组相比，实验组的这种 T2 关系的增加显着更高（P = 0.05）。对于母亲，T1 时喜好和感知健康之间的现有关系（τ中值 = 0.27，P 喜好和感知健康之间的关系在 T1 时不显着（τ中值 = -0.05，P = 0.56）在 T2 时变得显着且为正（τ中值 = 0.13，P = 0.002）。此外，与对照组相比，实验组的这种 T2 关系的增加显着更高（P = 0.05）。对于母亲，T1 时喜好和感知健康之间的现有关系（τ中值 = 0.27，P
