The impact of continuous glucose monitoring (CGM) on glycemic control in young adults with type 1 diabetes (T1D) is controversial. Data from 888 young adults with T1D were reviewed (ages 18-30 years, 52% female, glycated hemoglobin [HbA1c] 8.1% ± 1.5%). Prescription of CGM was recorded for 54% of young adults; 66% were pump users, 46% on insulin injections and carbohydrate (carb) counting, and 32% on insulin doses without carb counting ( ≤ 0.001). HbA1c was lower in young adults with CGM versus no CGM (7.7% ± 1.3% vs. 8.2% ± 1.7%, ≤ 0.001). Difference in HbA1c between CGM versus no CGM was greater in young adults noncarb counting (7.9% ± 1.4% vs. 8.9% ± 2.3%, = 0.002) than carb counting (7.7% ± 1.5% vs. 8.2% ± 1.7%, = 0.0008), or pump users (7.6 ± 1.2 vs. 7.9 ± 1.1, = 0.01). Prescription of CGM was higher with increasing complexity of insulin regimens; however, impact of CGM was greatest with simpler insulin administration methods. Further studies are needed to clarify this association.
连续血糖监测(CGM)对 1 型糖尿病(T1D)年轻患者血糖控制的影响存在争议。本研究回顾了 888 例 T1D 年轻患者的数据(年龄 18-30 岁,52%为女性,糖化血红蛋白 [HbA1c] 8.1%±1.5%)。记录了 54%的年轻患者 CGM 的使用情况;66%为胰岛素泵使用者,46%接受胰岛素注射和碳水化合物(carb)计数,32%接受无 carb 计数的胰岛素剂量( ≤ 0.001)。与无 CGM 相比,有 CGM 的年轻患者的 HbA1c 更低(7.7%±1.3%比 8.2%±1.7%, ≤ 0.001)。在不进行 carb 计数的年轻患者中,CGM 与无 CGM 相比,HbA1c 的差异更大(7.9%±1.4%比 8.9%±2.3%, = 0.002),而在进行 carb 计数的年轻患者中(7.7%±1.5%比 8.2%±1.7%, = 0.0008)或胰岛素泵使用者(7.6±1.2 比 7.9±1.1, = 0.01)中差异较小。胰岛素方案越复杂,CGM 的处方就越高;然而,CGM 的影响在胰岛素给药方法更简单时最大。需要进一步的研究来阐明这种关联。
