Abstract：
Since 1993, dietary assessment has been carried out in Greenland as part of recurrent population health surveys. In preparation for the next survey in 2024, 91 participants from the survey in 2018 were selected for a validation study of the Food Frequency Questionnaire (FFQ). The 91 participants were reinterviewed 38-50 months after the first FFQ and invited to complete a food diary. As part of the 2018 survey, blood was analysed for mercury. The food diary was completed by 65 participants. The agreement between the two FFQ interviews was very good for macronutrients and fatty acids (p > 0.20), whereas the calculated intake of mercury was 22% higher in the second FFQ (p = 0.04) due to a higher intake of whale meat and muktuk (whale skin). The agreement between the second FFQ and the food diary was good for local food, imported meat and cakes/sweets/snacks but fruit and vegetables, dairy products, beverages and added sugar were significantly underreported in the food diary. Food items not included in the FFQ were identified from the food diaries. The correlation between the intake of marine mammals and blood mercury was moderate (Spearman\'s rho = 0.41-0.50; p < 0.0001). The results will inspire future dietary studies in the circumpolar North.
摘要：
自1993年以来，格陵兰进行了饮食评估，作为经常性人口健康调查的一部分。在为2024年的下一次调查做准备时，从2018年的调查中选择了91名参与者进行了食物频率问卷（FFQ）的验证研究。91名参与者在第一次FFQ后38-50个月接受了重新采访，并被邀请完成一份食物日记。作为2018年调查的一部分，对血液中的汞进行了分析。食物日记由65名参与者完成。两次FFQ访谈之间的协议对常量营养素和脂肪酸非常好（p>0.20），而在第二个FFQ中，由于鲸鱼肉和muktuk（鲸皮）的摄入量较高，汞的计算摄入量增加了22％（p=0.04）。第二个FFQ和食物日记之间的协议对当地食物有好处，进口肉类和蛋糕/糖果/零食，但水果和蔬菜，乳制品,饮料和添加的糖在食物日记中被严重低估。从食品日记中确定了FFQ中未包含的食品。海洋哺乳动物的摄入量与血汞之间的相关性中等（Spearman的rho=0.41-0.50；p<0.0001）。该结果将启发极地北部地区未来的饮食研究。
