Body mass index moderates the association between diabetes distress and objective self‐management behaviours in adolescents with type 1 diabetes and elevated A1Cs
Authors' conclusion
Using objective behavioural data is useful for identifying how adolescent diabetes distress and zBMI affect daily bolusing behaviour amongst adolescent insulin pump users. Although distinct interventions exist to improve T1D self-management or diabetes distress, none addresses them together while considering zBMI. Decreasing diabetes distress could be especially important for youth with high zBMI.
Study context
- Population
- Adolescents with T1D using insulin pumps; 55.7% female, age 14.9 ± 1.9 years, T1D duration 6.6 ± 3.4 years
- Participants
- 79 adolescents
- Outcome
- Moderation by zBMI of the association between diabetes distress and self-management behaviours and A1C
Methodological detailsobjectively measured device data, multiple linear regression
- Objectively measured device data
- Multiple linear regression
Main finding
As reported in the abstract
zBMI × diabetes distress interaction, mean daily insulin boluses (b); higher zBMI and higher distress → fewer daily boluses
−0.02
p = 0.02
zBMI × diabetes distress interaction, blood glucose readings (b); not a moderator
−0.01
p = 0.29
zBMI × diabetes distress interaction, A1C (b); not a moderator
0.002
p = 0.81
Observational data: associations, not effects.
