BACKGROUND/OBJECTIVES: Several factors affect the mental performance of children. The importance that parents attribute to food-related determinants, compared with genetic, socio-economic and school environment, was investigated.
SUBJECTS/METHODS: Parents of school children (aged 4-11) were recruited through state primary schools in four European countries. Interviews were conducted in which participants were asked to sort 18 cards representing possible determinants of four elements of mental performance (attention, learning, mood and behaviour) according to perceived strength of effect. Determinants were identified from the literature and grouped in six categories: food-related, school environment, physical, social, psychological and biological. Effects were scored: 0=none; 1=moderate; and 2=strong. Views were compared between and within countries.
Two hundred parents took part (England: 53; Germany: 45; Hungary: 52; Spain: 50). Differences existed between countries in the proportions reporting university education and being in employment. Taking all countries together, parents consider the food category (mean 1.33) to have a lower impact on a child's mental performance than physical (activity and sleep, 1.77), psychological (mood and behaviour, 1.69) and school environment (1.57). Social (1.12) and biological (0.91) determinants were ranked lower than food. Of determinants in the food category, parents thought regularity of meals had more influence on mental performance (1.58) than what a child eats now (1.36), food at school (1.35), nutrition as a baby/infant (1.02).
Scope exists to improve parental awareness of the repercussions of their dietary choices for the mental performance of their children.
背景/目的:有几个因素会影响儿童的心理表现。本研究调查了父母对与食物相关的决定因素的重视程度,以及其与遗传、社会经济和学校环境相比的重要性。
受试者/方法:通过四个欧洲国家的公立小学招募了学童的父母。通过访谈,让参与者根据对四个心理表现(注意力、学习、情绪和行为)要素的影响程度,对代表 18 种可能决定因素的卡片进行分类。这些决定因素是从文献中确定的,并分为六类:与食物相关的、学校环境的、身体的、社会的、心理的和生物的。效应评分:0=无;1=中度;2=强。对各国之间和各国之内的观点进行了比较。
共有 200 名家长参与了此项研究(英国:53 名;德国:45 名;匈牙利:52 名;西班牙:50 名)。各国在接受大学教育和就业的比例上存在差异。将所有国家的数据综合起来,父母认为食物类别(均值 1.33)对儿童心理表现的影响低于身体因素(活动和睡眠,1.77)、心理因素(情绪和行为,1.69)和学校环境(1.57)。社会因素(1.12)和生物因素(0.91)的决定因素的排名低于食物。在食物类别中,父母认为用餐规律对儿童心理表现的影响更大(1.58),而孩子现在吃什么(1.36)、学校的食物(1.35)、婴儿/幼儿时期的营养(1.02)的影响较小。
有机会提高父母对其饮食选择对子女心理表现的影响的认识。
