A validation study of an interviewer-administered, seven-day semi-quantitative food frequency questionnaire (7-d SQFFQ) was conducted in Bangladeshi rural preschool age children. Using a cross-sectional study design, 105 children from 103 households were randomly selected. For the SQFFQ, a list of commonly consumed foods was adapted from the Bangladesh national micronutrient survey 2011-12. The data on the actual number of times and the amount of the children's consumption of the foods in the preceding 1 week were collected by interviewing the mothers. The intake was compared with two non-consecutive days 24-h dietary recalls conducted within 2 weeks after the SQFFQ. Validity was assessed by the standard statistical tests. After adjusting for the energy intake and de-attenuation for within-subject variation, the food groups (cereals, animal source foods, milk and the processed foods) had 'good' correlations between the methods (rho 0⋅65-0⋅93; < 0⋅001). Similarly, the macronutrients (carbohydrate, protein and fats) had 'good' correlations (rho 0⋅50-0⋅75; < 0⋅001) and the key micronutrients (iron, zinc, calcium, vitamin A, etc.) demonstrated 'good' correlations (rho 0⋅46-0⋅85; < 0⋅001). The variation in classifying the two extreme quintiles by the SQFFQ and the 24-h recalls was <10 %. The results from Lin's concordance coefficients showed a 'moderate' to 'excellent' absolute agreement between the two methods for food groups, and nutrients (0⋅21-0⋅90; < 0⋅001). This interviewer-administered, 7-d SQFFQ with an open-ended intake frequency demonstrated adequate validity to assess the dietary intake for most nutrients and suitable for dietary assessments of young children in Bangladesh.
在孟加拉国农村学龄前儿童中进行了一项访谈者管理的、为期 7 天的半定量食物频率问卷（7-d SQFFQ）的验证研究。采用横断面研究设计，从 103 户家庭中随机选择了 105 名儿童。对于 SQFFQ，从 2011-12 年孟加拉国国家微量营养素调查中改编了一份常见食用食物清单。通过访谈母亲，收集了过去 1 周儿童食用这些食物的实际次数和数量的数据。将摄入量与在 SQFFQ 后 2 周内进行的两次非连续 24 小时膳食回忆进行比较。使用标准统计检验评估有效性。在调整了能量摄入和个体内变异的衰减后，食物组（谷物、动物源食品、牛奶和加工食品）之间的方法具有“良好”的相关性（rho 0⋅65-0⋅93；<0⋅001）。同样，宏量营养素（碳水化合物、蛋白质和脂肪）具有“良好”的相关性（rho 0⋅50-0⋅75；<0⋅001），关键微量营养素（铁、锌、钙、维生素 A 等）表现出“良好”的相关性（rho 0⋅46-0⋅85；<0⋅001）。通过 SQFFQ 和 24 小时回忆来分类两个极端五分位数的变化<10%。Lin 的一致性系数的结果表明，两种方法在食物组和营养素方面具有“中等”到“极好”的绝对一致性（0⋅21-0⋅90；<0⋅001）。这种开放式摄入频率的访谈者管理的 7-d SQFFQ 具有足够的有效性，可以评估大多数营养素的饮食摄入量，适合评估孟加拉国幼儿的饮食。
