简要总结
The purpose of this study is to establish the reasonableness of using food-based photo diaries and continuous glucose monitors (CGM) to engage in counterfactual thinking strategies. These strategies may improve food choices among participants diagnosed with prediabetes (intervention group).
详细描述
The long-term objective of this project is to create a counterfactual-based lifestyle intervention that curtails the progression of prediabetes to T2DM through management and knowledge of food choices. This is a significant objective since 70% of prediabetes patients go on to develop T2DM. The project addresses a major objective of PATHS-UP in general and Thrust 4 in particular, by developing an innovative behavior-change intervention that will eventually make use of information from the Lab-on-your-Wrist device. To our knowledge, this is the first project to (1) propose an intervention based on counterfactual thinking for diabetes prevention and (2) combine continuous glucose monitors (CGMs) and food photography to promote a better understanding of how food choices affect blood glucose.The specific aim of this project is to establish the validity of leveraging photo-based food diaries and CGMs to engage counterfactual thinking strategies that improve food choices amongst prediabetes participants. This will be measured by changes in (1) eating attitudes and behaviors, (2) behavioral intentions to improve healthy eating behavior, (3) motivation to improve eating behavior, (4) increased self- efficacy for healthy eating, and (5) number of glucose excursions and time-in-range.

结局指标
主要结局
Change in number of glucose excursions and time in range
时间窗: Data will be collected in between study visits 1-4 (at baseline, 3 weeks, 4 weeks, and 6 weeks)
Collected via the Freestyle Libre Pro continuous glucose monitor placed on the participants' upper arm.
Change in HbA1C
时间窗: A blood sample will be collected at the screening visit, and at 6 weeks (Study Visit #4), 14 weeks (Study Visit #5), and 22 weeks (Study Visit #6).
Blood will be sampled through venipuncture technique on the upper arm. A blood sample of 4 mL will be collected for each measurement of the subject's A1c.
Change in average daily glucose level
时间窗: Data will be collected in between study visits 1-4 (at baseline, 3 weeks, 4 weeks, and 6 weeks)
Collected via the Freestyle Libre Pro continuous glucose monitor placed on the participants' upper arm.

- Change in the Eating Self-Efficacy Scale (ESES) scores(Data will be collected at baseline (Study Visit #1), 6 weeks (Study Visit #4), 14 weeks (Study Visit #5), and 22 weeks (Study Visit #6).)
- Change in the Behavioral Strategies - Engagement and Intentions score(Collected once per week over the first 6 weeks.)
