- Short sleep duration during childhood is associated with increased risk for later symptoms of emotional disorders in children and behavioral disorders in boys.
Why this matters
- Addressing sleep disturbances in children could reduce risk for later behavioral and psychological problems.
- Population-based cohort study of 799 Norwegian children from the Trondheim Early Secure Study.
- Sleep duration was assessed using the triaxial accelerometer and clinical interviews biennially from ages 6 to 12 years.
- Funding: Research Council of Norway; others.
- Symptoms of emotional disorders 2 years later were predicted by shorter sleep duration at ages:
- 6 years: unstandardized regression coefficient [β], −0.44 (P=.02); and
- 8 years: −0.47 (P=.01).
- Symptoms of behavioral disorders 2 years later were predicted (β) by shorter sleep duration at ages:
- 8 years: −0.65 (P=.03) boys vs −0.14 (P=.48) girls; and
- 10 years: −0.58 (P=.02) boys vs −0.05 (P=.84) girls.
- The association between emotional disorders and short sleep duration was significant for boys vs girls at ages 8 and 10 years (P<.001>
- The generalization of findings to other regions may be limited.
