Exposure to advertisements cannot fully explain the associations between young children's dietary intake and the time they spend in front of the television. It is therefore of importance to study television content other than advertisements in this aspect. The present study aimed to examine the nature and extent of verbal and visual appearances of foods and beverages in children's television programmes on Icelandic public service television.
A total of 27 h of children's programmes (domestic and internationally produced) were watched. All verbal and visual appearances of foods and beverages were coded, as well as the context in which the foods/beverages were discussed or appeared.

Two food groups were of special interest for their importance from a public health perspective: high-calorie and low-nutrient (HCLN) foods and fruits and vegetables (F&V). The χ 2 test and logistic regression were performed to analyse if the occurrence of the two groups was associated with the context where foods/beverages appeared.
Of the 125 different programmes, a food or beverage appeared in 86 %. Of the total food appearances (n 599), HCLN foods accounted for 26 % and F&V for 23 %. HCLN foods were presented as desirable by appearing more frequently with child characters (P<0·01) than F&V.
Public service television has the potential to improve the way food and eating is presented in children's programmes, as young childhood is a critical period for founding healthy habits for later life.
广告接触并不能完全解释儿童饮食摄入与他们看电视时间之间的关联。因此，在这方面研究电视内容（不仅仅是广告）非常重要。本研究旨在检查冰岛公共服务电视上儿童节目中食物和饮料的口头和视觉表现的性质和程度。
共观看了 27 小时的儿童节目（国内外制作）。对所有食物和饮料的口头和视觉表现，以及讨论或出现食物/饮料的背景进行了编码。

有两个食品组从公共卫生角度来看特别重要：高热量、低营养（HCLN）食品和水果及蔬菜（F&V）。采用 χ 2 检验和逻辑回归分析两组食物出现的情况是否与食物/饮料出现的背景有关。
在 125 个不同的节目中，有 86%的节目出现了食物或饮料。在总共出现的 599 种食物中，HCLN 食物占 26%，F&V 占 23%。HCLN 食物更频繁地出现在儿童角色身上，被认为是理想的（P<0·01），而 F&V 则不然。
公共服务电视有可能改善儿童节目中食物和饮食的呈现方式，因为儿童期是为以后的生活奠定健康习惯的关键时期。
