To develop a self-administered food frequency questionnaire for older children and adolescents and to demonstrate reproducibility over a 1-year period.
The youth/adolescent questionnaire (YAQ) was based on the validated Nurses' Health Study food frequency questionnaire and was developed to reflect the eating habits of this age group.
The multiethnic sample consisted of 179 youths (ages 9 to 18 years) who completed the questionnaire twice, 1 year apart.
Pearson correlation coefficients were calculated on nutrient data adjusted in relation to energy intake and on unadjusted food data.
Reproducibility for nutrients ranged from .26 for protein and iron to .58 for calcium, and for foods it ranged from .39 for meats to .57 for soda. Mean reproducibility was higher among girls than boys for energy and nutrients and for foods; no consistent pattern was observed for age.
A self-administered food frequency questionnaire has a reasonable ability to assess the eating habits of older children and adolescents over time.
为大龄儿童和青少年开发一份自行填写的食物频率问卷，并证明其在1年时间内的可重复性。
青少年问卷（YAQ）基于经过验证的护士健康研究食物频率问卷开发，旨在反映该年龄组的饮食习惯。
多民族样本包括179名青少年（9至18岁），他们在相隔1年的时间里两次填写问卷。
计算了根据能量摄入调整后的营养素数据以及未调整的食物数据的皮尔逊相关系数。
营养素的可重复性范围为蛋白质和铁的0.26至钙的0.58，食物的可重复性范围为肉类的0.39至汽水的0.57。女孩在能量、营养素和食物方面的平均可重复性高于男孩；未观察到年龄方面的一致模式。
一份自行填写的食物频率问卷有合理的能力评估大龄儿童和青少年一段时间内的饮食习惯。
