摘要

父母对儿童饮食行为的影响使父母成为以营养为重点的预防策略的明显目标。本研究利用对 153 名丹麦儿童（5-7 岁）进行的多成分群组随机干预 "你太甜了吗？"的数据，探讨了父母决定因素对儿童添加糖摄入量的中介效应和作用。干预前后的调查问卷评估了父母的知识、实践、自我效能、规范和态度。儿童的膳食摄入量根据七天的膳食记录进行估算。采用线性混合模型评估了儿童的添加糖摄入量与父母的反应之间的关联以及干预后父母反应的变化。儿童减少添加糖摄入量的部分原因是家长对限制在特殊场合摄入含糖量高的食品和饮料的规范和态度发生了变化。作为一种干预效果，家长对高糖食品和饮料摄入量指南的了解有所增加，但没有显示出中介效应。研究结果表明，在 "你太甜了吗？"干预研究中，家长对限制在特殊场合摄入含糖量高的食品和饮料的规范和态度是可以改变的，也是减少添加糖摄入量的中介因素：回顾性注册于 ISRCTN：ISRCTN10409779。

Parental norms and attitudes in Relation to Children’s sugar consumption − A mediation analysis of the “Are You Too Sweet?” intervention study

Parental influence on children’s dietary behaviour makes parents an obvious target for prevention strategies with nutritional foci. Mediation analysis is considered a valuable tool for understanding the underlying mechanisms of influence in intervention studies aimed at implementing behaviour change strategies.

The present study used data from the multi-component cluster-randomised intervention “Are You Too Sweet?” with 153 Danish children (5–7 years) to explore mediating effects and role of parental determinants on added sugar intake in children.

A pre-and post-intervention questionnaire evaluated parental knowledge, practices, self-efficacy, norms, and attitudes. Children’s dietary intake was estimated from a seven-day dietary record. Associations between children’s added sugar intake and parental responses and changes in responses following the intervention were evaluated using linear mixed models. Exploring potential behaviour change pathways of the intervention was done using mediation analyses.

Children’s reduction in added sugar consumption was partly mediated by changes in parental norms and attitudes regarding limiting sugar-rich foods and drinks to special occasions. Parental knowledge of guidelines on the intake of sugar-rich discretionary foods and drinks increased as an intervention effect but did not demonstrate a mediating effect. No significant changes or mediating effects were found in parental self-efficacy or practices.

The findings highlight parental norms and attitudes regarding restricting sugar-rich foods and drinks to special occasions as modifiable and a mediator for reducing added sugar intake in the “Are You Too Sweet?” intervention study.

期刊介绍： Food Quality and Preference is a journal devoted to sensory, consumer and behavioural research in food and non-food products. It publishes original research, critical reviews, and short communications in sensory and consumer science, and sensometrics. In addition, the journal publishes special invited issues on important timely topics and from relevant conferences. These are aimed at bridging the gap between research and application, bringing together authors and readers in consumer and market research, sensory science, sensometrics and sensory evaluation, nutrition and food choice, as well as food research, product development and sensory quality assurance. Submissions to Food Quality and Preference are limited to papers that include some form of human measurement; papers that are limited to physical/chemical measures or the routine application of sensory, consumer or econometric analysis will not be considered unless they specifically make a novel scientific contribution in line with the journal''s coverage as outlined below.
