随着在线饮食调整计划的热潮，需要在线饮食评估工具来获取食物摄入量。尽管美国农业部推荐了DASH(停止高血压的饮食方法)饮食，但目前还没有在线工具来捕捉DASH食物供应。我们的目标是评估一种新的、简短的在线饮食问卷的有效性，该问卷旨在记录DASH食物的摄入量。DASH在线问卷(OLQ)对照著名的集体食物频率问卷(FFQ)进行了验证。这是对DASH OLQ的横截面验证，它包含11个食品类别(早餐谷类；乳制品；饮料；脂肪和油；水果；谷物和零食；肉类、鱼类和家禽；混合菜肴；糖果；蔬菜；以及坚果、种子和豆类)。每个受试者在四周内每周完成一次DASH OLQ，在第2周至第4周完成一份98.2 Block FFQ(110道问题)。对DASH OLQ进行平均，然后与Block FFQ比较营养摄入量和DASH食物组的摄入量。波士顿大学医学中心，马萨诸塞州波士顿。波士顿大学医学中心191名教职员工，年龄在20-70岁之间。所有食物类别的BLOCK FFQ和DASH OLQ均呈显著正相关，从坚果/种子/豆类的r=0.8到蔬菜和混合菜肴的r=0.3。营养素摄入量的比较发现，在所有营养素类别中都存在很强的正相关关系。在DASH饮食和基于网络的营养和体力活动计划中，特别感兴趣的是总脂肪(r=0.62)、总碳水化合物(r=0.67)、总钾(r=0.68)、总钙(r=0.69)、总维生素C(r=0.60)和总能量摄入量(r=0.68)。与更成熟的Block FFQ相比，DASH OLQ很好地捕获了食物和营养的摄入量。
With the upsurge in online dietary modification programmes, online dietary assessment tools are needed to capture food intake. Although the DASH (Dietary Approaches to Stop Hypertension) diet is recommended by the US Department of Agriculture, there are no online instruments that capture DASH food servings. Our objective was to assess the validity of a new, short, online dietary questionnaire developed to capture intake of DASH food servings. The DASH Online Questionnaire (OLQ) was validated against the well-known Block Food Frequency Questionnaire (FFQ). This was a cross-sectional validation of the DASH OLQ, which contained eleven food groups (breakfast cereals; dairy; drinks; fats and oils; fruits; grains and snacks; meat, fish and poultry; mixed dishes; sweets; vegetables; and nuts, seeds and legumes). Each subject completed a DASH OLQ once weekly for four weeks and one 98.2 Block FFQ (110 questions) between weeks 2 and 4. DASH OLQ were averaged and then compared with the Block FFQ for nutrient intakes as well as intakes of DASH food groups. Boston University Medical Center, Boston, Massachusetts. One hundred and ninety-one faculty and staff at Boston University Medical Center aged 20–70 years. There were significant positive correlations between the Block FFQ and the DASH OLQ for all food groups ranging from r=0·8 for the nuts/seeds/legumes category to r = 0·3 for vegetables and mixed dishes. A comparison of nutrient intakes found strong positive correlations in all nutrient categories. Of particular interest in the DASH diet and the web-based nutrition and physical activity programme were total fat (r=0·62), total carbohydrate (r=0·67), total K (r=0·68), total Ca (r =0·69), total vitamin C (r=0·60) and total energy intake (r=0·68). The DASH OLQ captures food and nutrient intake well in relation to the more established Block FFQ.
