UNLABELLED OBJECTIVE OF THE PRESENT STUDY: To analyse the usual dietary habits of Belgian adolescents from a high cardiovascular risk population. METHODS A food frequency questionnaire (57 items) was administered to the whole sample. Complementary questions specified some types of food (eg fat content). A subgroup of 234 adolescents gave detailed information on portion size (picture book and food samples). SETTING Twenty-four secondary schools in the Belgian province of Luxembourg. SUBJECTS A total of 1,526 adolescents (12-17y) selected by a multiclustered stage sampling (participation: 83.6%). RESULTS Respectively 46% and 60% of the adolescents did not eat fruit and vegetables daily. Most of the adolescents (72%) consumed at least one dairy product daily. The frequent consumption of chocolate and French fries indicated the strong cultural influence on dietary habits while imported foods (like hamburgers) had little success. One-third of the adolescents (33%, n = 509) drank alcohol at least once a week and this proportion rose to 57% in the oldest age group. Boys and girls differed significantly in their diet, with girls choosing healthier foods. Dietary habits, in particular drinking habits, differed also significantly between education levels, assessed by the learning option of the participants. The semi-quantitative questionnaire showed that two-thirds of the adolescents had a lipid intake (mainly saturated fatty acids) which exceeded 35% of the total caloric intake. Complex carbohydrates represented less than half of the total carbohydrates intake. CONCLUSION The study of the diet of Belgian adolescents confirmed the strong influence of tradition, in particular on the consumption of high fat content foods. The promotion of healthy diet in adolescents should consider the cultural influence, even for this young age group.

青春期的饮食习惯-比利时Adolux研究的结果。

当前研究的未标清目标：分析来自高心血管风险人群的比利时青少年的饮食习惯。方法对整个样本进行食物频率问卷调查（57项）。补充问题规定了某些类型的食物（例如脂肪含量）。一个由234个青少年组成的小组提供了有关份量的详细信息（图画书和食物样本）。地点比利时卢森堡省的24所中学。研究对象通过多聚类阶段抽样（参与率：83.6％）选择了1,526名青少年（12-17岁）。结果分别有46％和60％的青少年每天不吃水果和蔬菜。大多数青少年（72％）每天至少消费一种乳制品。巧克力和薯条的频繁食用表明，饮食习惯对文化的影响很大，而进口食品（如汉堡包）收效甚微。三分之一的青少年（33％，n = 509）每周至少喝酒一次，而在年龄最大的年龄组中，这一比例上升到57％。男孩和女孩的饮食差异很大，女孩选择更健康的食物。饮食习惯，尤其是饮酒习惯，在教育水平之间也存在显着差异，这取决于参与者的学习选择。半定量调查表显示，三分之二的青少年脂质摄入量（主要是饱和脂肪酸）超过了总热量摄入的35​​％。复杂碳水化合物占碳水化合物摄入总量的不到一半。结论对比利时青少年饮食的研究证实了传统的强烈影响，特别是对高脂肪食品的消费。促进青少年健康饮食，甚至对于这个年轻年龄组，也应考虑文化影响。
