This study aimed to evaluate the relative validity of intake of energy, nutrients and food groups assessed with MijnEetmeter food diary as compared to 24-h dietary recalls, and if this differed between experienced and new users. One hundred men and women aged 18-70 y participated, of whom 47 had prior experience with the tool. Participants kept MijnEetmeter on three days. Trained dietitians called them three times for a 24-h dietary recall interview, once recalling food consumption on the same day as the food recording in MijnEetmeter. Systematic differences and correlations were assessed, and Bland-Altman plots were created; both for 3-day mean intakes and for intakes on the same day. Relative to 24-h dietary recalls, MijnEetmeter underestimated consumption of drinks, added fat, cereal products, and potatoes. Relative underestimation was observed for energy intake (6%) and about half of the nutrients. Experienced MijnEetmeter users underestimated intake the least. For intake of energy and six key nutrients, correlations between 3-day mean intakes were above 0.7 except for sodium intake. In conclusion, MijnEetmeter moderately underestimates intakes of energy and some nutrients and food groups. To improve the self-monitoring of dietary intake, it is recommended that the users record food consumption for several days and that the apps probes for easily forgotten foods and drinks.
本研究旨在评估使用 MijnEetmeter 食物日记评估的能量、营养素和食物组摄入量与 24 小时膳食回忆的相对有效性，并评估其在有经验和新用户之间是否存在差异。100 名年龄在 18-70 岁的男性和女性参加了这项研究，其中 47 名参与者之前使用过该工具。参与者使用 MijnEetmeter 记录三天的饮食。经过培训的营养师会在三天内三次通过电话进行 24 小时膳食回忆访谈，一次是在 MijnEetmeter 记录的同一天回忆食物摄入情况。评估了系统差异和相关性，并创建了 Bland-Altman 图；分别为 3 天的平均摄入量和同一天的摄入量。与 24 小时膳食回忆相比，MijnEetmeter 低估了饮料、添加脂肪、谷物产品和土豆的摄入量。能量摄入（6%）和大约一半的营养素也出现了相对低估。有经验的 MijnEetmeter 用户的低估程度最小。对于能量和六种关键营养素的 3 天平均摄入量的相关性，除了钠摄入外，均高于 0.7。总之，MijnEetmeter 适度低估了能量和一些营养素以及食物组的摄入量。为了改善膳食摄入的自我监测，建议用户记录几天的食物消费情况，并让应用程序探测容易被遗忘的食物和饮料。
