虽然能量失衡是儿童肥胖发展的关键，但反映在饮食质量分数中的不同饮食成分与儿童体重状况之间的联系尚未得到广泛研究。目前的研究确定，在以人口为基础的9至10岁英国儿童样本中，根据3个预先定义的分数表征的饮食质量是否与体重状况有关，而与先前与体重状况有关的因素无关。在一项对1700名儿童(56%的女孩)的横断面研究中，使用来自4-d食物日记的数据来计算3个经修改以反映儿童饮食的饮食质量评分：饮食质量指数(Doll)、健康饮食指标(HDI)和地中海饮食评分(MDS)。用7-d加速度计测量体力活动，客观测量身高、体重、腰围和生物阻抗，并用来计算体重状态变量。经过多次调整，包括体力活动和总体能量密度，较高的DQI和HDI得分与体重状况的改善显著相关。比较得分的极五分之一，DQI和HDI与腰围(分别为-3.0%，P=0.005和-2.5%，P=0.033)和下体脂肪(分别为-5.1%，P=0.023和-4.9%，P=0.026)相关。DQI还与较低的体重(-5.9%；P=0.002)和较低的体重(-4.2%；P=0.004)相关。没有观察到与MDS有显著关联。这些发现表明，饮食质量与儿童的体重状况独立相关。未来的工作应该考虑饮食质量评分是否可以成为旨在减少儿童肥胖的干预措施的关键组成部分。J.Nutr.141：453-459,2011。
Although energy imbalance is key to the development of childhood obesity, the association between different dietary components, reflected in diet quality scores, and children's weight status has not been extensively studied. The current study determined, if diet quality, characterized according to 3 predefined scores, was associated with weight status in a population-based sample of 9- to 10-y-old British children, independently of factors previously associated with weight status. In a cross-sectional study of 1700 children (56% girls), data from 4-d food diaries were used to calculate 3 diet quality scores modified to be reflective of children's diets: the Diet Quality Index (Doll, Healthy Diet Indicator (HDI), and Mediterranean Diet Score (MDS). Physical activity was measured with 7-d accelerometery, and height, weight, waist, and bio-impedance Were objectively measured and used to calculate weight status variables. After multiple adjustments, including physical activity and overall energy density, higher DQI and HDI scores were significantly associated with improved weight status. Comparing extreme quintiles of the scores revealed the DQI and HDI were associated with lower waist circumference (-3.0%, P = 0.005 and -2.5%, P = 0.033, respectively), and lower body fat (-5.1%, P = 0.023 and -4.9%, P = 0.026, respectively). The DQI was also associated with lower weight (-5.9%; P = 0.002) and BM) (-4.2%; P = 0.004). No significant associations were observed with the MDS. These findings suggest that diet quality is independently associated with children's weight status. Future work should consider if diet quality scores could be key components of interventions designed to reduce obesity in children. J. Nutr. 141: 453-459, 2011.
