Behavioral self-control and glycemic levels in youth with type 1 diabetes: serial mediation by family conflict and self-management behaviors
Authors' conclusion
BSC has substantial potential for influencing glycemic levels as it is directly associated with lower HbA1c and helps to optimize glycemic levels by decreasing FC and increasing SMB during late adolescence.
Study context
- Population
- Adolescents with T1D (mean age 16 years), followed for 3 years at 3 medical centers
- Participants
- 172 adolescents
- Outcome
- Serial mediation of the BSC–HbA1c relationship by family conflict (FC) and diabetes self-management behaviors (SMB)
- Follow-up
- Baseline, 12, 24 and 36 months
Methodological detailsmulticentre, longitudinal and cross-sectional serial mediation analyses, HbA1c measured twice yearly in a central laboratory
- Multicentre
- Longitudinal and cross-sectional serial mediation analyses
- HbA1c measured twice yearly in a central laboratory
Main finding
As reported in the abstract
Serial mediation: BSC → FC → SMB → HbA1c
- Ten independent models tested (five self-reported, five parent-reported family conflict (FC) and self-management behaviors (SMB))
- 10
Observational data: associations, not effects.
