研究概览
简要总结
This is a one-group pilot study where Chinese immigrants who are English speaking with T2D from NYU Langone Health and NYU Brooklyn Family Health Center (Sunset Park) will be recruited.
详细描述
To evaluate the estimation accuracy using eButton, researchers will collect carbohydrate data via weighing food by registered dietitian nutritionist (RDN) ("gold standard") (2 days/week at research labs) and food diaries by participants (2 days/week at research labs and 3 days/ week at participant home). Then, the estimated carb grams will be compared head to head among each other. Assessment will be at 0 and 2 weeks, including surveys and qualitative audio interview.

结局指标
主要结局
Accuracy of Carbohydrate Counting using eButton (absolute error)
时间窗: Day 14
The estimated carb grams using the eButton, gold standard, and participants' food diaries will be compared head to head among each other. The absolute error will be computed: the difference between the estimated value and the gold standard (estimated - gold standard). Bland-Altman plots will be used to examine the level of agreement between eButton and gold standard measurements.
Accuracy of Carbohydrate Counting using eButton (relative error)
时间窗: Day 14
The estimated carb grams using the eButton, gold standard, and participants' food diaries will be compared head to head among each other. The relative error will be computed: the percentage difference between the estimated value relative to the gold standard. Relative errors will be reported using boxplots to allow visual comparison of the distribution and variability in errors across all methods. Bland-Altman plots will be used to examine the level of agreement between eButton and gold standard measurements.
Proportion of participants who are fully compliant with eButton use
时间窗: Day 14
Proportion of participants who are fully compliant with eButton use and proportion of meals evaluated using eButton, with 95% confidence intervals will be qualitatively reported. Perceived usefulness and perceived ease of use will be summarized as mean and standard deviation.
