In Bangladesh, two food composition tables (FCTs) were published over two consecutive years, in 2012 and in 2013. When different databases are used to calculate nutrient intakes, assessment of divergence and agreements is required. This study aimed to compare the differences in nutrient intakes, to assess the similarities in nutrient intakes between the two FCTs, and to explore the factors that cause the difference in nutrient intakes, if any. A total sample of 40 households was taken from the Household Income Expenditure Survey of 2010. Adult male equivalent (AME) units were used to estimate weighted average intake. Weighted k statistics were used to assess agreements between the two FCTs. Although median intake of energy and energy-yielding nutrients (protein, fats, and carbohydrates) were found statistically significant between the two databases, the differences were not large enough to have practical significance. Excellent agreements were found in energy and carbohydrates with good for fats and fair for protein. However, statistically significant median percent differences were seen in beta carotene (441%), vitamin B6 (153%), and folate (129%), vitamin C (106%), zinc (101%), and iron (41%) intakes. For thiamin, iron, calcium, and phosphorous, more than 50% of the subjects were found in the same quintile, whereas nine out of 15 vitamins and minerals were misclassified into the opposite quintiles (≥10%). Fair agreements were found for most of the micronutrients. Variations in analytical methods and sources of nutrient information were the main contributing factors for actual differences. FCT data should be interpreted with caution, especially for micronutrients.
在孟加拉国，2012 年和 2013 年连续两年发布了两份食物成分表 (FCT)。当使用不同的数据库来计算营养素摄入量时，需要评估差异和一致性。本研究旨在比较两种 FCT 之间的营养素摄入量差异，评估两者之间的营养素摄入量相似性，并探讨是否存在导致营养素摄入量差异的因素。从 2010 年的家庭收入支出调查中抽取了总共 40 户家庭作为样本。使用成人男性当量 (AME) 单位来估计加权平均摄入量。使用加权 k 统计量评估两种 FCT 之间的一致性。尽管两种数据库之间的能量和产能营养素（蛋白质、脂肪和碳水化合物）的中位数摄入量存在统计学差异，但差异不足以具有实际意义。能量和碳水化合物之间的一致性极好，脂肪的一致性良好，蛋白质的一致性尚可。然而，β-胡萝卜素（441%）、维生素 B6（153%）和叶酸（129%）、维生素 C（106%）、锌（101%）和铁（41%）的摄入量的中位数百分比差异具有统计学意义。对于硫胺素、铁、钙和磷，超过 50%的受试者处于相同的五分位数，而 15 种维生素和矿物质中有 9 种被错误地归入相反的五分位数（≥10%）。大多数微量营养素的一致性尚可。分析方法和营养素信息来源的差异是造成实际差异的主要因素。FCT 数据的解释应谨慎，特别是对于微量营养素。
