Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

118
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Summary

Adolescents with concussion experience poorer sleep quality. The Pittsburgh Sleep Quality Index (PSQI) with a cut point of 4 effectively distinguishes concussed adolescents from controls.

Area of Science:

  • Neurology
  • Sleep Medicine
  • Adolescent Health

Background:

  • Concussions significantly impact adolescent sleep quality.
  • The Pittsburgh Sleep Quality Index (PSQI) is a common tool for assessing sleep impairments.
  • Existing PSQI scoring criteria require validation for differentiating sleep quality in concussed adolescents.

Purpose of the Study:

  • To establish a clinically relevant Pittsburgh Sleep Quality Index (PSQI) cut point for identifying sleep disturbances in adolescents following a concussion.

Main Methods:

  • A cross-sectional study involving 110 concussed adolescents and 129 uninjured controls.
  • Participants completed the Pittsburgh Sleep Quality Index (PSQI).
  • Logistic regression and receiver operating characteristic (ROC) curve analysis were used to determine the optimal PSQI cut point.

Main Results:

  • Adolescents with concussion reported significantly worse sleep quality (higher PSQI scores) than controls (P < .001).
  • The multivariable model demonstrated excellent diagnostic accuracy (AUC = 0.99).
  • A PSQI cut point of 4 achieved 87% sensitivity and 74% specificity in distinguishing concussed from uninjured adolescents.

Conclusions:

  • Adolescents with concussion exhibit poorer sleep quality compared to their uninjured peers.
  • The Pittsburgh Sleep Quality Index (PSQI), with a cut point of 4, can effectively differentiate sleep quality between concussed and non-concussed adolescents.
