Tailored nutritional guidance by a registered dietitian is necessary for feasible, practical application of nutrition therapy. In order to reduce the requirement for estimation by a dietitian and to increase the time available for practical advice, we developed and validated computer software for estimating dietary intake among patients with type 2 diabetes. The study enrolled 46 patients with type 2 diabetes, recruited from an outpatient clinic in 2015. We used the computer software "Syokuseikatsu Shindan System" (SSS; Nissha, Kyoto, Japan). SSS allows the user to choose pictures of dishes and the portions he/she has consumed for each meal. The one-day dietary intake estimations for SSS were validated against a reference estimation of 24-h dietary recall by a registered dietitian. The mean carbohydrate intake as assessed by SSS and 24-h recall was 210.6 ± 55.1 and 215.5 ± 52.9 g/day, with a positive correlation ( = 0.53, <0.001). Bland-Altman analysis showed that limits of agreement in carbohydrates between the methods were -107.4 to 97.5 g/day. Even though the limits of agreement were wide and non-negligible at the individual level for clinical use, SSS appears to have potential as a dietary estimation tool under registered dietitian supervision.
注册营养师提供的个性化营养指导对于营养疗法切实可行的实际应用而言是必要的。为了减少营养师进行估算的需求并增加用于实际建议的时间，我们开发并验证了一款用于估算2型糖尿病患者饮食摄入量的计算机软件。该研究纳入了2015年从一家门诊诊所招募的46例2型糖尿病患者。我们使用了计算机软件“生活习惯诊断系统”（SSS；日本京都日差株式会社）。SSS允许用户选择每餐所食用菜肴的图片及其份量。通过注册营养师进行的24小时饮食回顾参考估算对SSS的一日饮食摄入量估算进行了验证。通过SSS和24小时回顾评估的平均碳水化合物摄入量分别为210.6±55.1克/天和215.5±52.9克/天，呈正相关（=0.53，<0.001）。Bland-Altman分析表明，两种方法在碳水化合物方面的一致性界限为-107.4至97.5克/天。尽管在个体层面上一致性界限较宽且在临床使用中不可忽略，但SSS在注册营养师的监督下似乎有作为饮食估算工具的潜力。
