这项分析的目的是检查算法驱动的在线糖尿病预防计划对饮食习惯，身体活动和健康/生产力因素变化的影响。这项名为Alive-PD的干预措施使用了小步个体定制的目标设定和其他功能，以促进饮食和体育活动的改变。在来自医疗保健提供系统的确诊为前驱糖尿病的患者（n =339）中进行了一项为期6个月的随机对照试验。在诊所测量体重和血糖标志物的变化。身体活动、饮食和健康/生产力因素的变化是自我报告的。平均年龄为55岁（s.d. 8.9)平均体重指数为31（s.d. 4.4)kg m−2，68%为白色，69%为男性。干预组每周增加水果/蔬菜摄入量3.71次（95%置信区间（CI）2.73，4.70）（效应量0.62），每周减少精制碳水化合物3.77次（95% CI 3.10，4.44），均显著（P<0.001）大于对照组。干预组的体力活动也比对照组显著增加，效应量为0.49，P<0.001。此外，与对照组相比，干预组报告了自我评估健康状况的显着增加，对改变饮食和完成任务的能力的信心以及疲劳的减少。这些变化证实了对血糖标志物和体重的显著治疗效应。除了促进体重和血糖标志物的改善外，Alive-PD计划似乎还改善了饮食习惯和身体活动，这些行为不仅对糖尿病预防很重要，对那些诊断为糖尿病或肥胖的人也很重要。健康/生产力的改善可能来自饮食和活动的改善，以及实现目标的满意度和自我效能。
The purpose of this analysis is to examine the effect of an algorithm-driven online diabetes prevention program on changes in eating habits, physical activity and wellness/productivity factors. The intervention, Alive-PD, used small-step individually tailored goal setting and other features to promote changes in diet and physical activity. A 6-month randomized controlled trial was conducted among patients from a healthcare delivery system who had confirmed prediabetes (n =339). Change in weight and glycemic markers were measured in the clinic. Changes in physical activity, diet and wellness/productivity factors were self-reported. Mean age was 55 (s.d. 8.9) years, mean body mass index was 31 (s.d. 4.4) kg m−2, 68% were white and 69% were male. The intervention group increased fruit/vegetable consumption by 3.71 (95% confidence interval (CI) 2.73, 4.70) times per week (effect size 0.62), and decreased refined carbohydrates by 3.77 (95% CI 3.10, 4.44) times per week both significantly (P<0.001) greater changes than in the control group. The intervention group also reported a significantly greater increase in physical activity than in the control group, effect size 0.49, P<0.001. In addition, the intervention group reported a significant increase in self-rated health, in confidence in ability to make dietary changes and in ability to accomplish tasks, and a decrease in fatigue, compared with the control group. These changes paralleled the significant treatment effects on glycemic markers and weight. In addition to promoting improvements in weight and glycemic markers, the Alive-PD program appears to improve eating habits and physical activity, behaviors important not just for diabetes prevention but for those with diagnosed diabetes or obesity. The improvements in wellness/productivity may derive from the diet and activity improvements, and from the satisfaction and self-efficacy of achieving goals.
