The aim of the present study was to assess if a simple dietary quality index (SDQI) is a useful indicator for nutritional quality in the Danish diet. Data from the Danish National Dietary Survey 2000-2 for adults (n 3151; age 18-75 years) were used to construct an SDQI based on the intake of dietary fibre and saturated fat. The SDQI was used to rank the individuals into three subgroups: the 25 % closest in meeting the recommended intakes of saturated fat and dietary fibre (compliers), the 25 % furthest away (non-compliers) and the 50 % in between (intermediates). Significant differences in food and nutrient intake between these subgroups were identified by intakes of food groups and intakes of nutrients followed by non-parametric tests. Compared with the Nordic Nutrition Recommendations 2004 and the Danish Dietary Guidelines 2005, compliers had a significantly better nutrient profile than intermediates and non-compliers, as the diet of compliers contained more whole-grain cereals, fruits, vegetables and fish, and more frequently low-fat dairy products, lean meats and boiled potatoes. The diet of all subgroups, especially non-compliers, had a high content of nutrient-poor, energy-dense foods, for example, salty snacks, confectionery, and beverages, for example, soft drinks and alcohol. The SDQI is a simple and useful tool to characterise the diet quality of Danish adults.
本研究的目的是评估一种简单饮食质量指数（SDQI）是否是丹麦饮食营养质量的有用指标。利用2000 - 2002年丹麦全国成年人饮食调查数据（n = 3151；年龄18 - 75岁），基于膳食纤维和饱和脂肪的摄入量构建了SDQI。SDQI用于将个体分为三个亚组：在饱和脂肪和膳食纤维摄入量最接近推荐摄入量的25%（依从者），距离最远的25%（不依从者）以及介于两者之间的50%（中间者）。通过食物组摄入量和营养素摄入量，随后进行非参数检验，确定了这些亚组之间食物和营养素摄入量的显著差异。与《2004年北欧营养建议》和《2005年丹麦饮食指南》相比，依从者的营养状况明显优于中间者和不依从者，因为依从者的饮食包含更多的全谷物、水果、蔬菜和鱼类，并且更频繁地食用低脂乳制品、瘦肉和煮土豆。所有亚组的饮食，尤其是不依从者的饮食，富含营养成分低、能量密集的食物，例如咸味小吃、糖果以及饮料，例如软饮料和酒精。SDQI是描述丹麦成年人饮食质量的一种简单而有用的工具。
