Diabetes self-management education is an essential element of diabetes care. Systems based on information and communication technology (ICT) for supporting lifestyle modification and self-management of diabetes are promising tools for helping patients better cope with diabetes. An earlier study had determined that diet improved and HbA1c declined for the patients who had used DialBetics during a 3-month randomized clinical trial. The objective of the current study was to test a more patient-friendly version of DialBetics, whose development was based on the original participants' feedback about the previous version of DialBetics.
DialBetics comprises 4 modules: data transmission, evaluation, exercise input, and food recording and dietary evaluation. Food recording uses a multimedia food record, FoodLog. A 1-week pilot study was designed to determine if usability and compliance improved over the previous version, especially with the new meal-input function.
In the earlier 3-month, diet-evaluation study, HbA1c had declined a significant 0.4% among those who used DialBetics compared with the control group. In the current 1-week study, input of meal photos was higher than with the previous version (84.8 ± 13.2% vs 77.1% ± 35.1% in the first 2 weeks of the 3-month trial). Interviews after the 1-week study showed that 4 of the 5 participants thought the meal-input function improved; the fifth found input easier, but did not consider the result an improvement.
DialBetics with FoodLog was shown to be an effective and convenient tool, its new meal-photo input function helping provide patients with real-time support for diet modification.
糖尿病自我管理教育是糖尿病护理的重要组成部分。基于信息通信技术（ICT）支持糖尿病生活方式改变和自我管理的系统是帮助患者更好应对糖尿病的有前景的工具。一项早期研究确定，在为期3个月的随机临床试验中使用DialBetics的患者饮食得到改善，糖化血红蛋白（HbA1c）下降。本研究的目的是测试一个对患者更友好的DialBetics版本，其开发基于原始参与者对先前版本DialBetics的反馈。
DialBetics包括4个模块：数据传输、评估、运动输入以及食物记录和饮食评估。食物记录使用多媒体食物记录软件FoodLog。设计了一项为期1周的试点研究，以确定其可用性和依从性是否比先前版本有所改善，特别是新的 meal-input 功能。
在早期为期3个月的饮食评估研究中，与对照组相比，使用DialBetics的患者糖化血红蛋白显著下降了0.4%。在当前为期1周的研究中，meal photos 的输入率高于先前版本（3个月试验的前2周为84.8 ± 13.2%，而先前为77.1% ± 35.1%）。1周研究后的访谈显示，5名参与者中有4人认为meal-input功能有所改善；第五名参与者觉得输入更容易，但不认为结果有改善。
带有FoodLog的DialBetics被证明是一种有效且方便的工具，其新的meal-photo输入功能有助于为患者提供饮食调整的实时支持。
