目的：研究中等营养价值的食物对美国儿童和青少年饮食的贡献。方法：数据来自1988年至1994年第三次全国健康与营养检查调查，包括4852名8至18岁的儿童和青少年。在24小时饮食召回中报告的食物被分为以下低营养密度（LND）食物类别：可见脂肪;餐桌甜味剂，糖果和含糖饮料;烘焙和乳制品甜点;咸味小吃;和杂项。LND食品的数量在召回中提到的食物组，常量营养素，微量营养素和体重指数的摄入量的独立协会进行了检查，通过回归程序调整多个协变量。结果：LND食品贡献了超过30%的日常能量，与甜味剂和甜点共同占近25%。总能量摄入量和碳水化合物和脂肪能量百分比与LND食物报告数量呈正相关，而蛋白质和膳食纤维能量百分比（以克计）与LND食物报告数量呈负相关（P
Objective: To examine the contribution of foods of modest nutritional value to the diets of American children and adolescents.Methods: The data were from the third National Health and Nutrition Examination Survey, 1988 to 1994, and included 4852 children and adolescents, aged 8 to 18 years. Foods reported in the 24-hour dietary recall were grouped into the following low-nutrient-density (LND) food categories: visible fat; table sweeteners, candy, and sweetened beverages; baked and dairy desserts; salty snacks; and miscellaneous. The independent association of the number of LND foods mentioned in the recall with intake of food groups, macronutrients, micronutrients, and body mass index was examined by means of regression procedures to adjust for multiple covariates.Results: The LND foods contributed more than 30% of daily energy, with sweeteners and desserts jointly accounting for nearly 25%. intakes of total energy and percentage of energy from carbohydrate and fat related positively, but percentage of energy from protein and dietary fiber (in grams) related inversely to the reported number of LND foods (P
