The association between family environment and child's eating behaviors is well established but a multidimensional approach to study this relation is lacking. This study aimed to assess the proprieties of a questionnaire created to evaluate parental practices, preferences, skills and attitudes regarding fruit and vegetables (F&V), sugar and salt. Participants (n = 714) were families of pre-school children (aged 2-6 years old) of the Nutriscience Project-a web-based gamification program-who answered a questionnaire assessing socio-demographic characteristics, nutrition knowledge, and a scale evaluating parental practices, preferences, skills and attitudes, at the baseline of the project. Exploratory factorial analysis was applied to the scale: 21 items and 5 factors were extracted (52.4% of explained variance) with a Kaiser-Meyer-Olkin (KMO) value of 0.770: 1. Modelling/active promotion of F&V consumption (α = 0.73), 2. Skills for choosing/preparing healthy food (α = 0.75), 3. Food preferences and satiety perception (α = 0.70), 4. Awareness regarding sugar/salt intake (α = 0.61), 5. Allowance regarding F&V consumption (α = 0.55). Kruskal-Wallis and Mann-Whitney tests were conducted to compare factors according to socio-demographic characteristics. Higher scores for parental modelling and active promotion of F&V consumption were observed in older parents, those with higher nutrition knowledge and who reported to live without income difficulties. Regarding food preferences, higher scores were observed in mothers, with higher nutrition knowledge and from higher educated groups. Higher awareness regarding salt and sugar consumption were observed in older parents, with higher education, higher nutrition knowledge and with female children. Older parents and with female children also registered higher scores of skills for choosing/preparing healthy food. The scale showed satisfactory proprieties and may contribute to assess family food environment using a multidimensional approach. It also highlighted the importance of considering socio-demographic characteristics in interventions to promote healthy eating.
家庭环境与儿童饮食行为之间的关系已得到充分证实,但缺乏多维方法来研究这种关系。本研究旨在评估一个旨在评估父母关于水果和蔬菜(F&V)、糖和盐的实践、偏好、技能和态度的问卷的适当性。参与者(n=714)为学前儿童(年龄 2-6 岁)的 Nutriscience 项目-一个基于网络的游戏化项目-的家庭,他们在项目的基线阶段回答了一个问卷,评估社会人口统计学特征、营养知识以及评估父母实践、偏好、技能和态度的量表。对量表进行探索性因子分析:提取了 21 个项目和 5 个因素(解释方差的 52.4%),Kaiser-Meyer-Olkin(KMO)值为 0.770:1. 模拟/积极促进 F&V 消费(α=0.73),2. 选择/准备健康食品的技能(α=0.75),3. 食物偏好和饱腹感感知(α=0.70),4. 对糖/盐摄入量的认识(α=0.61),5. 对 F&V 消费的允许(α=0.55)。进行 Kruskal-Wallis 和 Mann-Whitney 检验,根据社会人口统计学特征比较因素。在年龄较大的父母、营养知识较高且报告没有收入困难的父母中,观察到父母对 F&V 消费的模拟和积极促进的分数较高。在食物偏好方面,营养知识较高且来自教育程度较高群体的母亲得分较高。在年龄较大的父母、受过较高教育、营养知识较高且有女孩的父母中,对盐和糖消费的认识较高。年龄较大的父母和有女孩的父母也记录了选择/准备健康食品技能的更高分数。该量表表现出良好的特性,可用于多维方法评估家庭食物环境。它还强调了在促进健康饮食的干预措施中考虑社会人口统计学特征的重要性。
