Objective Sleep and Circadian Metrics in Adolescents With Type 1 Diabetes Mellitus: A Systematic Review

J Diabetes Sci TechnolPublished Systematic review

Authors' conclusion

In adolescents with T1DM, disturbed sleep involves insufficient duration, fragmentation, variability, and circadian misalignment. Sleep efficiency and regularity showed more consistent associations with glycaemic outcomes than duration alone

Study context

Population
Adolescents aged 10 to 19 years with T1D; objective sleep or circadian measures10 studies
Outcome
Objective sleep and circadian parameters and associations with glycaemic outcomes
Methodological detailsPRISMA 2020, narrative synthesis (Synthesis Without Meta-analysis)

Pooled result

As reported in the abstract

Mean total sleep time (suboptimal sleep duration)

6.8-7.6 h/night

Further pooled results

Randomized evidence: closed-loop therapy vs standard care

RCTs
2
Neither demonstrated sustained improvements in objective sleep outcomes or glycaemic control

Study designs and risk of bias

Studies with a healthy control group
1
Most were single-cohort observational designs, limiting causal inference
Risk of bias moderate in cross-sectional and low to moderate in cohort studies
