“…In our study, long sleep duration was more common in women. This was in line with other studies showing that men usually sleep less hours, although women reported having more sleep problems 40. However, this relationship is complex and could depend on family composition (eg, single parents have shorter sleep duration, particularly women) 41…”

ObjectivesWe estimated the prevalence of short sleep duration and multimorbidity in Luxembourg, and assessed whether sleep duration was associated with multimorbidity after adjusting for sociodemographic and behavioural characteristics.DesignCross-sectional study.ParticipantsData from 1508 Luxembourg residents (48% men and 52% women) aged 25 to 64 years came from the European Health Examination Survey 2013–2015.Outcome measuresShort sleep duration and multimorbidity.ResultsParticipants reported sleeping 6.95 hours/night during work days, nearly 1 hour less than during non-work days (7.86 hours/night). Nearly half of participants reported having been diagnosed with ≥2 chronic conditions/diseases. Short sleep duration was associated with the number of chronic conditions (OR 4.65, 95% CI 1.48 to 14.51; OR 7.30, 95% CI 2.35 to 22.58; OR 6.79, 95% CI 2.15 to 21.41 for 1, 2 and ≥3 chronic conditions/diseases, respectively), independently of socioeconomic and behavioural characteristics.ConclusionsHealth promotion programmes should aim at improving and promoting healthy lifestyles among the general population to improve sleep habits as well as decrease multimorbidity in middle-aged adults.

“…Thus, considering the reported effect of age and gender on the primary phenotype of our study (insufficient or disturbed sleep 20,21 ), and, furthermore, the fact that most (81%) of the participants in the Airline sample were < 50 (n = 26), we focused on men < 50 years old in the DILGOM sample (n = 79) in the subsequent analyses. However, as age has an important effect on DNA methylation, it was included in all analyses as a covariate.…”

Short sleep duration or insomnia may lead to an increased risk of various psychiatric and cardio-metabolic conditions. Since DNA methylation plays a critical role in the regulation of gene expression, studies of differentially methylated positions (DMPs) might be valuable for understanding the mechanisms underlying insomnia. We performed a cross-sectional genome-wide analysis of DNA methylation in relation to self-reported insufficient sleep in individuals from a community-based sample (79 men, aged 39.3 ± 7.3), and in relation to shift work disorder in an occupational cohort (26 men, aged 44.9 ± 9.0). The analysis of DNA methylation data revealed that genes corresponding to selected DMPs form a distinctive pathway: “Nervous System Development” (FDR P value < 0.05). We found that 78% of the DMPs were hypomethylated in cases in both cohorts, suggesting that insufficient sleep may be associated with loss of DNA methylation. A karyoplot revealed clusters of DMPs at various chromosomal regions, including 12 DMPs on chromosome 17, previously associated with Smith-Magenis syndrome, a rare condition comprising disturbed sleep and inverse circadian rhythm. Our findings give novel insights into the DNA methylation patterns associated with sleep loss, possibly modifying processes related to neuroplasticity and neurodegeneration. Future prospective studies are needed to confirm the observed associations.

“…There is evidence from previous studies that during normal working days people sleep less than they prefer to. 26 This is often referred to as the concept of "social jet lag" -the misalignment between a person's circadian and social clocks (measured as the difference in hours at the midpoint of sleep between work days and days off). 27 During the weekends, or other times when people have more leisure time, sleep duration is longer 26 and sleep deprivation over the week may be compensated for.…”

“…Previous studies have focused only on the associations of gender, age, mental health status, and circadian preference with changes in sleep duration during the transition to retirement. 4 Information has been lacking on how various other correlates of sleep duration, such as poor self-rated health, 6 alcohol use, 20 and smoking, 5,26 are associated with the changes in sleep duration during the retirement transition.…”

Study Objectives: This study examined whether sleep duration changes during the transition from full-time work to statutory retirement and, if this were the case, which pre-retirement factors, including sociodemographic, work, lifestyle and health factors, predict these changes. [CI] 6 h 54 min to 7 h 6 min) to 7 hours and 22 minutes (95% CI 7 h 16 min to 7 h 27 min); thus, mean increase being 22 minutes. Increase in sleep duration was greatest in those who were short sleepers, heavy drinkers or had sleep difficulties. After the retirement transition, sleep duration remained at approximately the same level, as no significant changes were observed. Methods Conclusions:This longitudinal study suggests that transition from full-time work to statutory retirement is associated with an increase in sleep duration.
