“…Findings extend previous studies showing sleep variability is associated with mood symptoms (Gruber et al, 2011; Saunders et al, 2015). However, while we found overall variability in sleep duration was associated with more negative and less positive affect ratings, day-to-day atypicality relative to one's average sleep duration was not associated with day-to-day affect ratings.…”

“…Sleep duration and variability has typically been evaluated with cross-sectional surveys (Goossens et al, 2010), and longitudinal studies with time points spaced months, or even years, apart (Gruber et al, 2011; Perlman et al, 2006; Saunders et al, 2015). Studies have employed actigraphy to measure sleep in bipolar patients, but sleep duration in these studies was only measured for one or two weeks (Harvey et al, 2005; Jones et al, 2005; Millar et al, 2004) and concurrent mood ratings were collected at one time point (Harvey et al, 2005; Jones et al, 2005) or by daily mood diary entries (Gershon et al, 2012; Millar et al, 2004).…”

OBJECTIVE Sleep disturbances are prevalent, persistent, and impairing features of bipolar disorder. However, the near-term and cumulative impact of the severity and variability of sleep disturbances on symptoms and functioning remains unclear. We examined self-reported daily sleep duration and variability in relation to mood symptoms, medication adherence, cognitive functioning, and concurrent daily affect. METHODS Forty-one outpatients diagnosed with bipolar disorder were asked to provide daily reports of sleep duration and affect collected via ecological momentary assessment with smartphones over eleven weeks. Measures of depressive and manic symptoms, medication adherence, and cognitive function were collected at baseline and concurrent assessment of affect were collected daily. Analyses examined whether sleep duration or variability were associated with baseline measures and changes in same-day or next-day affect. RESULTS Greater sleep duration variability (but not average sleep duration) was associated with greater depressive and manic symptom severity, and lower medication adherence at baseline, and with lower and more variable ratings of positive affect and higher ratings of negative affect. Sleep durations shorter than 7-8 hours were associated with lower same-day ratings of positive and higher same-day ratings of negative affect, however this did not extend to next-day affect. CONCLUSIONS Greater cumulative day-to-day sleep duration variability, but not average sleep duration, was related to more severe mood symptoms, lower self-reported medication adherence and higher levels of negative affect. Bouts of short- or long-duration sleep had transient impact on affect. Day-to-day sleep variability may be important to incorporate into clinical assessment of sleep disturbances in bipolar disorder.

“…Only duration of sleep was comparable in all analyzed groups. Our results are consistent with those presented by Wang and others (2014) and Geoffroy and colegues (2014) for BPD patients, as well as with the results presented by Saunders and others (2015) for UPD patients , Saunders et al 2015.…”

Genetic background and clinical picture of mood disorders (MD) are complex and may depend on many genes and their potential interactions as well as environmental factors. Therefore, clinical variations, or endophenotypes, were suggested for association studies.The aim of the study was to investigate association between the chronotype (CH) and quality of sleep characteristics with polymorphisms CLOCK, ARNTL, TIMELESS and PER3 genes in MD. We included a total sample of 111 inpatients and 126 healthy controls. To assess CH we applied Morningness-Eveningness Questionnaire (MEQ). Additionally, we defined the quality and patterns of sleep using The Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). We applied Kruskal-Wallis test to determine associations. The main positive findings refer to associations between selected polymorphisms and: 1) chronotype with the ARNTL gene (rs11824092 and rs1481892) and the CLOCK (rs1268271), 2) sleep duration with the CLOCK gene (rs3805148) and the TIM gene (rs2291739), 3) daytime dysfunction with the PER3 gene (rs228727, rs228642, rs10864315), 4) subjective sleep quality with the ARNTL gene (rs11824092, rs1982350), 5) sleep disturbances with the ARNTL gene (rs11600996).We also found the significant epistatic interactions between polymorphism of the PER3 gene (rs2640909) & the CLOCK gene (rs11932595) and following sleep quality variables: sleep duration, habitual sleep efficiency and subjective sleep quality.The present study suggests a putative role of the analyzed clock genes polymorphisms in chronotype in the control group and in sleep quality disturbances in the course of MD. The results indicate that PSQI variables can be used to refine phenotype in association studies of clock genes in MD.

“…Impaired sleep is partly associated with depression and anxiety disorders affecting females more frequently than males. A US longitudinal study also confirmed lower sleep quality in females than males, with poor sleep being a significant predictor of low mood (Saunders et al, 2015). Lower sleep quality in females with rheumatoid arthritis proved Czech study (Kaas, Tóthová, 2015).…”

Aim: The study aimed at assessing the quality of sleep in seniors. Another objective was to determine the impact of gender, age, type of residence and taking sleeping medication on the quality of sleep. Design: A cross-sectional study. Methods: Data were collected using the standardized Pittsburgh Sleep Quality Index (PSQI) questionnaire. The sample comprised 146 seniors living in the Moravian-Silesian Region, Czech Republic. The survey was conducted from January 2014 to the end of October 2014 in a long-term chronic care department of a selected hospital, two retirement homes and among seniors living in their own homes. Results: Thirty-five (24%) seniors had their global PSQI scores of 5 (i.e. the highest score indication good sleep quality) or less. The remaining 111 (76%) participants were shown to suffer from impaired sleep quality as their global PSQI scores were 6 or higher. There were statistically significant differences in component scores between seniors with the global PSQI scores of 5 or less and those with higher scores. The best quality of sleep was observed in females, seniors in the 65-74 age category and those sharing their own homes with their spouses or partners. Conclusion: Subjective sleep quality assessment varies significantly with respect to gender, age, type of residence and use of sleeping medication.
