Many children consume excessive amounts of energy-dense, nutrient-poor (EDNP) or 'extra' foods and low intakes of fruit and vegetables. The aim of this study was to examine the associations between EDNP foods and ascertain whether certain EDNP foods and beverages are more likely to be eaten in association with other EDNP foods.
A cross-sectional representative population survey of children in preschool (n=764), and of school students in Years K, 2 and 4 (n=1,560) and in Years 6, 8 and 10 (n=1,685) residing in the Hunter New England region of New South Wales, Australia. Dietary data were collected using a short food frequency questionnaire. Multivariate logistic regression models examined the association between EDNP foods and fruit and vegetable intake. Data were stratified by sex and age cohort.
More frequent consumption of some EDNP food types was significantly associated with more frequent consumption of other EDNP foods. Fast food and soft drinks consumption were associated with each other as well as with fried potato and salty snacks; and with lower intakes of fruit and vegetables in some but not all age groups.
The positive associations found between EDNP foods point towards the existence of a high-risk group of children who frequently consume a variety of EDNP foods and drinks.
许多儿童摄入过多的高热量、低营养（EDNP）或“额外”食物，而水果和蔬菜摄入量较低。本研究的目的是研究 EDNP 食物之间的关联，并确定某些 EDNP 食物和饮料是否更有可能与其他 EDNP 食物一起食用。
在澳大利亚新南威尔士州亨特新英格兰地区对学龄前儿童（n=764）以及 K 年、2 年和 4 年（n=1,560）和 6 年、8 年和 10 年（n=1,685）的在校学生进行了一项具有代表性的横断面人群调查。使用简短的食物频率问卷收集饮食数据。多变量逻辑回归模型检查了 EDNP 食物与水果和蔬菜摄入量之间的关联。按性别和年龄组分层数据。
某些 EDNP 食物类型的频繁消费与其他 EDNP 食物的频繁消费显著相关。快餐和软饮料的消费相互关联，与炸薯条和咸点心也有关联；并且与某些但不是所有年龄组的水果和蔬菜摄入量较低有关。
EDNP 食物之间发现的正相关关系表明，存在一组高风险儿童，他们经常食用各种 EDNP 食物和饮料。
