OBJECTIVE To evaluate long-term glycemic outcomes of continuous glucose monitoring (CGM) initiation within the first year of type 1 diabetes diagnosis. RESEARCH DESIGN AND METHODS Patients with type 1 diabetes (N = 396) were divided into three groups: 1) CGM (CGM use within 1 year of diabetes diagnosis and continued through the study), 2) no-CGM (no CGM use throughout the study), and 3) new-CGM (CGM use after 3 years since diabetes diagnosis). Patients were followed up to 7 years. RESULTS A1c was significantly lower in the CGM compared with the no-CGM group throughout 7 years of follow-up (least squares mean A1c values: 6 months, 7.3% vs. 8.1%; 1 year, 7.4% vs. 8.6%; 2 years, 7.7% vs. 9.1%; 3 years, 7.6% vs. 9.3%; 4 years, 7.4% vs. 9.6%; 5 years, 7.6% vs. 9.7%; 6 years, 7.5% vs. 10.0%; and 7 years, 7.6% vs. 9.8%; for all, P < 0.001) adjusting for age at diagnosis, sex, and insulin delivery method. CONCLUSIONS CGM initiation within first year of type 1 diabetes diagnosis results in long-term improvement in A1c.

在 1 型糖尿病诊断的第一年内启动持续血糖监测与改善血糖结果相关：7 年随访研究

目的 评估在诊断 1 型糖尿病的第一年内开始连续血糖监测 (CGM) 的长期血糖结果。研究设研究）和 3）新 CGM（糖尿病诊断后 3 年后使用 CGM）。患者随访长达 7 年。结果 在 7 年的随访中，CGM 组的 A1c 显着低于非 CGM 组（最小二乘平均 A1c 值：6 个月，7.3% 对 8.1%；1 年，7.4% 对 8.6%；2年，7.7% 对 9.1%；3 年，7.6% 对 9.3%；4 年，7.4% 对 9.6%；5 年，7.6% 对 9.7%；6 年，7.5% 对 10.0%；和7 年，7.6% 对 9.8%；对于所有情况，P < 0。001) 调整诊断时的年龄、性别和胰岛素输送方法。结论 在诊断 1 型糖尿病的第一年内开始 CGM 会导致 A1c 的长期改善。
