Valid and useful dietary assessment methods for adolescents with type 1 diabetes (T1D) are needed. In this study, we compared an image-based method with a written food diary for dietary intake estimation among adolescents with T1D and evaluated the adolescents' experiences of the methods. Adolescents with T1D aged 13 to 18 years ( = 13) photographed their meals ( = 264) with a mobile phone camera and simultaneously kept a written food diary for four consecutive days. The participants filled out electronic background and feedback questionnaires. The agreement between the methods was evaluated using intraclass correlation coefficients (ICCs) and Bland-Altman plot analyses. The agreement between the methods was moderate to excellent for the energy intake (ICC = 0.91, 95% confidence interval (CI): 0.66 to 0.97, < 0.001) and good to excellent for total carbohydrate intake (ICC = 0.95, 95% CI: 0.84 to 0.99, < 0.001). The adolescents considered photographing easier and faster than keeping a food diary. In conclusion, the image-based method appeared comparable to the food diary for dietary intake estimation among adolescents with T1D. The photographing of meals may become a useful dietary assessment tool for adolescents with T1D, but must be further developed and validated.
需要为1型糖尿病（T1D）青少年提供有效且实用的饮食评估方法。在本研究中，我们比较了一种基于图像的方法和书面食物日记在T1D青少年饮食摄入量估计中的应用，并评估了青少年对这些方法的体验。13至18岁的T1D青少年（ = 13）用手机摄像头拍摄他们的餐食（ = 264），并同时连续四天记录书面食物日记。参与者填写了电子背景和反馈问卷。使用组内相关系数（ICC）和布兰德 - 奥特曼图分析来评估方法之间的一致性。两种方法在能量摄入方面的一致性为中等至优秀（ICC = 0.91，95%置信区间（CI）：0.66至0.97， < 0.001），在总碳水化合物摄入量方面为良好至优秀（ICC = 0.95，95% CI：0.84至0.99， < 0.001）。青少年认为拍照比记录食物日记更容易、更快。总之，对于T1D青少年的饮食摄入量估计，基于图像的方法似乎与食物日记相当。餐食拍照可能成为T1D青少年有用的饮食评估工具，但必须进一步开发和验证。
