Accelerometry‐assessed sleep clusters and cardiometabolic risk factors in adolescents
Main finding · Sex-scaled FMIResult — go to the resultβ 0.39 95% CI 0.15–0.62Authors' conclusion
The prolonged sleep latency cluster was associated with higher FMI in adolescents, whereas the sleep irregularity and variability cluster was specifically linked to elevated triglycerides (≥1.7 mmol/L) in male individuals.
Study context
- Population
- Adolescents aged 14.3 to 16.4 years (mean 15.2) wearing 7-day accelerometers, GINIplus and LISA birth cohorts, Germany505 with cardiometabolic data
- Participants
- 1,090 adolescents
- Exposure
- Accelerometry-assessed sleep clusters vs good sleep cluster
- Good sleepn = 337reference
- Delayed sleep phasen = 244
- Sleep irregularity and variabilityn = 108
- Fragmented sleepn = 313
- Prolonged sleep latencyn = 88
- Outcome
- Sex-scaled fat mass index (FMI)
