Abstract

Objective: This study investigated the accuracy of a flash glucose monitoring system (FGMS) in a postprandial setting.

Methods: Ten fasted adults without diabetes wore the FGMS sensors then consumed a standard breakfast. Their glucose levels were subsequently recorded for 2 hours, both by the FGMS and by measuring capillary glucose levels using the glucose oxidase method. The accuracy of the FGMS data was assessed using the accuracy limits stated in ISO 15197:2013.

Results: FGMS measurements were mostly lower than glucose oxidase measurements (mean absolute relative difference ± SD: 25.4 ± 17.0%, p < 0.001). However, the maximum difference from baseline captured by the two methods was not significantly different (mean ± SD, glucose oxidase: 58.5 ± 18.9 mg/dl; FGMS, 54.4 ± 28.9 mg/dl, p = 0.366).

Conclusions: FGMS could track the incremental glycaemic excursions after meals in adults without diabetes, yet further studies with greater sample sizes are needed to confirm this finding.

在营养学研究中，快速血糖监测可以准确反映健康成人餐后血糖的变化。

目的:本研究探讨餐后血糖瞬时监测系统(FGMS)的准确性。方法:10名没有糖尿病的禁食成年人戴上FGMS传感器，然后吃一顿标准早餐。随后，通过FGMS和葡萄糖氧化酶法测量毛细血管葡萄糖水平，记录他们的血糖水平2小时。使用ISO 15197:2013中规定的精度限制来评估FGMS数据的准确性。结果:FGMS测定值大多低于葡萄糖氧化酶测定值(平均绝对相对差±SD: 25.4±17.0%，p SD，葡萄糖氧化酶:58.5±18.9 mg/dl;FGMS为54.4±28.9 mg/dl, p = 0.366)。结论:FGMS可以追踪非糖尿病成年人餐后血糖的增加，但需要进一步的研究来证实这一发现。
