A new web-based food frequency questionnaire (the ASSO-FFQ) was developed within the ASSO Project funded by the Italian Ministry of Health.
The aim of the present study is to assess the validity of the ASSO-FFQ at food groups, energy, and nutrients level.
The validation study compared the ASSO-FFQ against a weighted food record (WFR) measuring foods, beverages and supplements intake, compiled during the week following the ASSO-FFQ administration. Ninety-two subjects aged 14-17, recruited from secondary schools in Palermo (Italy), completed the ASSO-FFQ and WFR. The intake of 24 food groups, energy, and 52 nutrients were taken as main outcomes. Tests for paired observations, Spearman and Pearson's correlation coefficients (cc), kappa statistics and classification in quintiles, Bland-Altman plots and multiple regressions, on untransformed and transformed data were used for the statistical analysis.
High cc (≥0.40) were found for soft drinks, milk, tea/coffee, vegetables, and lactose; fair energy-adjusted cc (0.25-0.40) for water, alcoholic drinks, breakfast cereals, fishery products, savory food, fruit juice, eggs, and 19 nutrients. The subjects classified in the same or adjacent quintile for food groups ranged from 40% (alcoholic drinks) to 100% (dried fruit); for energy and nutrients from 43% (phosphorus, thiamin, niacin) to 77% (lactose). Mean differences were not significant for water, soft drinks, meat, sweets, animal fats, milk and white bread, and vitamin B12 and folate. Limits of Agreement were broad for all food groups and nutrients. School, gender, alcohol consumption and between meals mainly affected most food groups' intake differences. Gender stratification showed females had increased Pearson's cc for energy and 28 nutrients, such as almost all fats, carbohydrates, vitamins and minerals.
The ASSO-FFQ could be applied in epidemiological studies for the assessment of dietary consumption in adolescents to adequately rank food, energy and nutrient intakes at a group level.
在意大利卫生部资助的ASSO项目中开发了一种新的基于网络的食物频率问卷（ASSO-FFQ）。
本研究的目的是评估ASSO-FFQ在食物组、能量和营养素水平上的有效性。
本验证研究将ASSO-FFQ与在ASSO-FFQ调查后一周内编制的用于测量食物、饮料和补充剂摄入量的加权食物记录（WFR）进行了比较。从意大利巴勒莫的中学招募了92名14至17岁的研究对象，他们完成了ASSO-FFQ和WFR。将24个食物组、能量和52种营养素的摄入量作为主要研究结果。对未转换和转换后的数据进行配对观察检验、Spearman和Pearson相关系数（cc）、kappa统计和五分位数分类、Bland-Altman图以及多元回归分析。
软饮料、牛奶、茶/咖啡、蔬菜和乳糖的cc值较高（≥0.40）；水、酒精饮料、早餐谷物、渔业产品、咸味食品、果汁、鸡蛋和19种营养素的能量调整后cc值中等（0.25 - 0.40）。食物组中分类在相同或相邻五分位数的研究对象比例从40%（酒精饮料）到100%（干果）不等；能量和营养素方面从43%（磷、硫胺素、烟酸）到77%（乳糖）不等。水、软饮料、肉类、糖果、动物脂肪、牛奶和白面包以及维生素B12和叶酸的平均差异不显著。所有食物组和营养素的一致性界限都较宽。学校、性别、饮酒情况和餐间因素主要影响了大多数食物组的摄入量差异。按性别分层显示，女性能量和28种营养素的Pearson相关系数增加，如几乎所有的脂肪、碳水化合物、维生素和矿物质。
ASSO-FFQ可应用于流行病学研究，以评估青少年的饮食消费情况，在群体水平上对食物、能量和营养素摄入量进行充分排序。
