Quality—not quantity—of sleep linked to better health in teens
As she explains, she found that chronic, low-quality sleep was associated with poorer health outcomes among young B.C. students aged 13 to 17.

Chronic sleep disturbance, not chronic sleep deprivation, is associated with self-rated health in adolescents,

Improving our understanding of the cumulative effects of persistent sleep problems on adolescent health has been identified as an important area of research. This prospective study aimed to ascertain prospectively gender-specific associations between quantity and quality of sleep and self-reported health. Data from a cohort of 3104 adolescents (13–18 y) with repeated measures of sleep deprivation and sleep disturbance (2011 fall, 2012 spring, 2012 fall), and self-reported health (SRH) (2011 fall, 2012 fall) were analysed with multivariable logistic regression models adjusted for confounders. The results of the regression models indicated that cumulative exposure to sleep disturbance was monotonically associated with SRH in both genders, however cumulative sleep deprivation was not associated with self-reported health among young people. Young women reporting chronic exposure to sleep disturbance had over twice the odds of reporting sub-optimal health at follow-up (OR 2.18 [CI95: 1.13, 4.22]), compared to those with no history. Similar results were found in chronically sleep disturbed young men (OR 2.41 [1.05, 5.51]). These findings suggest that chronic exposure to impaired quality of sleep, such as difficulty falling or staying asleep, is related to adolescent self-reported health and thus may be an important determinant of young people’s wellbeing.
