Text Message Intervention for Teens with Type 1 Diabetes Preserves HbA1c: Results of a Randomized Controlled Trial.

: Teens with type 1 diabetes (T1D) often struggle with diabetes self-management, which may lead to suboptimal self-care and worsening hemoglobin A1c (HbA1c). Innovative strategies are needed to improve self-care and protect against glycemic decline, especially during adolescence. We aimed to assess the impact on HbA1c of two interventions, problem-solving and text messaging, in teens with T1D.
