该研究评估在新发1型糖尿病青少年中,早期启动持续葡萄糖监测(CGM)并针对社会人口学障碍提供项目支持是否与差异减少和血糖改善相关。研究比较历史、试点和研究1三个队列,发现研究1中部分差异(尤其保险和族裔)减弱,但剥夺指数和种族/族裔仍是HbA1c变异的主要贡献因素。

要点

  • 早期CGM联合项目支持与部分血糖差异减弱相关,尤其保险和族裔方面。
  • 研究1中非西班牙裔白人、低剥夺、私人保险和英语偏好者HbA1c最低。
  • 剥夺指数(41.3%)和种族/族裔(32.2%)是HbA1c变异的主要贡献因素。

核心结论

  • 研究1与血糖结局改善及部分差异减弱相关,尤其保险和族裔方面,支持4T项目作为有效的公平导向照护模式。
  • 剥夺指数是模型推导的HbA1c变异关键贡献因素,可能是减少儿科1型糖尿病血糖差异的重要靶点。

研究设计与样本

  • 在4T项目中,新发1型糖尿病青少年在诊断后<1个月启动CGM,接受远程监测并以HbA1c<7%为目标。
  • 按种族和族裔、保险、剥夺和语言分层评估HbA1c,比较历史队列(2014年6月至2016年12月)、试点队列(2018年7月至2020年6月)和研究1队列(2020年6月至2022年3月)。

主要发现

  • 研究1中12个月时,非西班牙裔白人HbA1c为6.5%(95%CI 6.2%-6.9%),低剥夺为6.5%(95%CI 6.2%-6.9%),私人保险为6.6%(95%CI 6.3%-7%),英语偏好为6.7%(95%CI 6.4%-7%)。
  • 族裔斜率从历史0.09(95%CI -0.02至0.20)变为试点0.14(95%CI -0.04至0.31)再变为研究1 0.08(95%CI -0.07至0.23)。
  • 保险斜率从历史0.20(95%CI 0.09-0.31)改善至试点0.12(95%CI -0.06至0.29)再至研究1 0.01(95%CI -0.14至0.16)。
  • 剥夺(41.3%)和种族/族裔(32.2%)对HbA1c变异的贡献最大。

临床怎么用

  • 对于新发1型糖尿病青少年,可考虑早期启动CGM并结合针对社会人口学障碍的项目支持。
  • 关注剥夺指数高的患者,可能有助于减少血糖差异。

OBJECTIVE: To assess, in youth with type 1 diabetes (T1D), whether the initiation of early continuous glucose monitoring (CGM) with programmatic support to address sociodemographic barriers is associated with reduced disparities and improved glycemia. STUDY DESIGN: CGM was initiated <1 month postdiagnosis with remote monitoring and <7% glycosylated hemoglobin A1c (HbA1c) target in youth with new-onset T1D in the Teamwork, Targets, Technology, and Tight Glycemia program. We evaluated HbA1c stratified by race and ethnicity, insurance, deprivation, and language across 3 cohorts: historical (June 2014 to December 2016), pilot (July 2018 to June 2020), and study 1 (June 2020 to March 2022). RESULTS: At 12 months in study 1, HbA1c was lowest among non-Hispanic White (6.5%; 95% CI 6.2%-6.9%), low deprivation (6.5%; 95% CI 6.2%-6.9%), private insurance (6.6%; 95% CI 6.3%-7%), and English preference (6.7%; 95% CI 6.4%-7%). HbA1c disparities were attenuated in study 1: ethnicity slopes changed from historical (0.09; 95% CI -0.02 to 0.20) to pilot (0.14; 95% CI -0.04 to 0.31) to study 1 (0.08; 95% CI -0.07 to 0.23). Insurance slopes improved from historical (0.20; 95% CI 0.09-0.31) to pilot (0.12; 95% CI -0.06 to 0.29) to study 1 (0.01; 95%CI -0.14 to 0.16). Deprivation (41.3%) and race and ethnicity (32.2%) contributed most to HbA1c variability. CONCLUSIONS: Study 1 was associated with improved glycemic outcomes and attenuation of some disparities, particularly by insurance and ethnicity, supporting the Teamwork, Targets, Technology, and Tight Glycemia program as an effective equity-oriented care model. Deprivation emerged as a key model-derived contributor to variability in HbA1c and may represent an important target to reduce disparities in pediatric T1D glycemia.
