Facilitating the Virtual Exercise Games for Youth with T1D (ExerT1D) Peer Intervention: Protocol Development and Feasibility (2024)

ABSTRACT

Background Barriers to moderate-to-vigorous physical activity (MVPA) for adolescents with type 1 diabetes (T1D) include physiology, transition to autonomy, and diabetes-specific stigma. Opportunities for T1D peer activities with T1D role model support are limited. To address this need, our single-arm pilot study tested the Home-based Virtual Activity Program for Youth with T1D (HAP-V-T1D) for feasibility.

Methods Participants (n=15) were mean age 15.6 [SD 1.5] years, 7 non-Hispanic white, 6 female, 2 non-binary, mean A1c 8.9%±2.2%. The program included an MVPA videogame, physician-led education regarding managing T1D around MVPA, objective habitual MVPA goal-setting , and T1D management skills guided by young adult instructors living with T1D.

Results For feasibility, 13/15 participants attended 10/12 sessions. Participants’ perceptions of the program, comfort, instructors, and group cohesion were rated high/very high (4.2±0.5 to 4.8±0.3 out of 5).

Motivation for the videogame was also high (4.1±0.4 out of 5). Instructor-adolescent interactions related to building T1D management skills were rated as excellent for 78% of sessions. Similarly, sharing knowledge and experiences were rated as excellent for 68% of sessions. However, adolescent-adolescent interactions were poor (communication 29% excellent, peer interactions 8% excellent). The most reported barriers to participation were negative mood and oversleeping. No participants experienced diabetic ketoacidosis, severe hypoglycemia, or injuries during the study period. Compared to baseline, glycemic metrics appeared to decrease during and post intervention (d= -0.72, -1.12).

Conclusion HAP-V-T1D facilitated unprecedented T1D peer support achievements by engaging diverse youth with T1D in an MVPA program led by T1D role models. Larger studies are needed to assess if this intervention can improve glycemic measures and reduce diabetes-specific stigma.
