“…Subjects who have high apprehensions towards the next working day show abbreviated SWS periods and lower scores in subjective sleep quality. Furthermore, SWS in depressed patients has been documented to have a positive correlation with the subjective estimation of sleep duration (Rotenberg et al, 2000). Given that the S4-sleep period is important for sleep quality, our findings suggest that light sources of higher color temperatures may reduce sleep quality compared with those of lower color temperatures.…”

In order to examine whether the spectral compositions of light source may affect sleep quality, sleep architecture under different color temperatures of light sources was evaluated. Seven healthy males were exposed to the light sources of different color temperatures (3000 K, 5000 K and 6700 K) for 6.5 h before sleep. The horizontal illuminance level was kept at 1000 lux. Subjects slept on a bed in near darkness (Ͻ10 lux) after extinguishing the light, and polysomnograms recorded the sleep parameters. In the early phase of the sleep period, the amount of stage-4 sleep (S4-sleep) was significantly attenuated under the higher color temperature of 6700 K compared with the lower color temperature of 3000 K. Present findings suggest that light sources with higher color temperatures may affect sleep quality in a view that S4-sleep period is important for sleep quality.

“…Previous studies showed that pregnant women with a depressive disorder report more fragmented sleep, as refl ected in longer sleep latencies and poorer sleep effi ciency, than pregnant women without a depressive disorder. 10,11 Non-pregnant patients with depression and sleep problems also showed discrepancy between subjective and objective sleep measurements 12 -e.g., objective sleep quality-as measured by actigraphy more closely approximated those of the golden standard (polysomnography) than subjective measurements in depressed insomniacs. 13 It is unclear whether sleep quality in pregnant women is objectively worse in a sense of reduced or fragmented sleep, or whether their perception of it is altered, possibly as a result of co-occurring psychiatric symptoms.…”

Objective: Disturbed sleep during pregnancy is associated with adverse obstetric outcomes and less mental well-being. In pregnant women with a mental disorder, who frequently suffer from sleep problems, it is unknown whether predominantly objective or subjective sleep quality is more affected. To clarify this, we compared objective and subjective parameters of sleep quality between patients and healthy controls during pregnancy. Methods: This observational study was embedded in an ongoing study among pregnant women with a mental disorder at the department of Psychiatry of Erasmus University Medical Center Rotterdam, the Netherlands. We compared 21 pregnant women with a confi rmed mental disorder with 33 healthy controls (gestational age, 23-29 weeks). To measure objective parameters of sleep quality, all participants continuously wore a wrist actigraph for 7 days and nights. Subjective sleep quality was retrospectively assessed using the Pittsburgh Sleep Quality Index (PSQI) and on a daily basis with the Subjective Sleep Quality-scale (SSQ). Differences in parameters of sleep between patients and controls were tested using a multivariate linear regression analysis adjusted for parity, gestational age, educational level, and employment status. Results: Objective parameters of sleep quality and subjective sleep quality as assessed by the PSQI did not differ signifi cantly between patients and controls. Daily sleep reports showed that, relative to controls, patients had a signifi cantly worse average SSQ-score (5.2 vs. 7.6, adjusted β = 0.12, 95%CI = 0.03-0.53, p < 0.01). Conclusions: Our exploratory study suggests that perceived sleep quality reported on a daily basis by pregnant women with a mental disorder is worse than the sleep quality as measured by wrist actigraphy.

“…For instance those with depression have a greater tendency to rate sleep more poorly compared to PSG measures than people without depression. 35 Studies relying on self reported measures of sleep, therefore, may provide biased data on relationships between objective sleep measures and depression.…”

A large community study reported a rate of 17% and reports for sleep clinic samples range between 21% and 41%. A large cohort study found OSA to be a risk factor for depression, but we are unaware of any longitudinal study of the reverse association. However correlations have not generally been found in smaller studies. Well-designed longitudinal studies are needed to examine temporal relationships between the two conditions and further research is needed to establish the role of confounders, and effect modifiers such as gender, in any apparent relationship. Symptoms common to OSA and depression, such as sleepiness and fatigue, are obstacles to determining the presence and severity of one condition in the presence of the other, in research and clinically. Sleep clinicians are advised to consider depression as a likely cause of sleepiness and fatigue. Several possible causal mechanisms linking OSA and depression have been proposed but not established. Patients who have depression as well as OSA appear worse off than those with OSA only, and depressive symptoms persist in at least some patients in short term studies of treatment for OSA. Direct treatment of depression in OSA might improve acceptance of therapy, reduce sleepiness and fatigue and improve quality of life, but intervention trials are required to answer this question.
