Nagel KE, Dearth-Wesley T, Herman AN, et al. - Among young adults with type 1 diabetes (T1D), experts aspired to explore if higher levels of dispositional mindfulness were correlated with lower HbA_1c levels and if this relationship varied by age or exposure to adverse childhood experiences. In 2017, 423 of 743 young adults (19-31 years) completed an online cross-sectional survey, called T1 Flourish, of T1D seeking outpatient care at a specialty diabetes clinic in New York City. In young adults with T1D, higher mindfulness was significantly linked to lower HbA1c only among 27- to 31-year-olds. The impact of mindfulness-based interventions on glycemic control in early adulthood may vary by age and history of childhood trauma.
