“…Sleep disturbances can include parasomnias such as nightmares, sleepwalking, periodic limb movements, and spontaneous awakenings that occur after falling asleep 26,27 . External factors can contribute to sleep disturbances, such as medications, electronic devices, and shift work that requires daytime sleep 26,28,29 …”

Sleep quality: An evolutionary concept analysis

Aim To clarify the meaning of the concept sleep quality. Background Sleep loss and sleep quality are global health concerns. Poor sleep quality has significant adverse health outcomes. A clarification of the term is necessary to inform patients and healthcare providers, promote consistent theoretical and operational definitions in research, and develop prevention and treatment strategies. Design Concept analysis. Data Sources Scientific literature from electronic databases (CINAHL, PsycINFO, PubMED, Web of Science, and JSTOR) and definitions from online dictionaries. Review Methods Rodgers' Evolutionary method was applied to guide the concept analysis to identify and determine the attributes, antecedents, and consequences. Results Sleep quality is defined as an individual's self‐satisfaction with all aspects of the sleep experience. Sleep quality has four attributes: sleep efficiency, sleep latency, sleep duration, and wake after sleep onset. Antecedents include physiological (e.g., age, circadian rhythm, body mass index, NREM, REM), psychological (e.g., stress, anxiety, depression), and environmental factors (e.g., room temperature, television/device use), and family/social commitments. Good sleep quality has positive effects such as feeling rested, normal reflexes, and positive relationships. Poor sleep quality consequences include fatigue, irritability, daytime dysfunction, slowed responses, and increased caffeine/alcohol intake. Conclusions Sleep quality is essential, and poor sleep quality contributes to disease and poor health outcomes. Given the extensive consequences of poor sleep quality, nurses and clinicians are vital in instructing the importance of good sleep.

“…Poor sleep is a serious public health problem. It is estimated that the incidence of poor sleep quality was 8.3% among residents (1), and up to 42.5% in the working population (2). Growing evidence suggests that it is also quite prevalent in the middle-aged population (3), postmenopausal women (4), the elderly (5), cancer patients (6), and those suffering from mental and chronic diseases (3).…”

Objective: Pilates exercise is increasingly used to improve sleep quality, but relevant evidence remains unclear. We aimed to estimate the effect of Pilates on sleep quality.Methods: Five databases were searched for articles published until 10 December 2019. Two investigators screened the articles and extracted data from each included study. A meta-analysis was performed to evaluate the effect of Pilates on sleep quality, assessed using the Pittsburgh Sleep Quality Index (PSQI).Results: Six randomized controlled trials (RCTs) comprising 477 participants were included according to the inclusion and exclusion criteria in the study. All included studies reported the positive effects Pilates had on sleep quality. The Pilates group (PG) significantly lowered the PSQI total score (MD = −3.60, 95%CI: [−5.41, −1.78), P = 0.0001, I 2 = 97%) compared to the non-exercising control group (CG), whereas no significant improvement in use of sleep medication was observed (MD = −0.33, 95%CI: [−0.73, −0.06), P = 0.10, I 2 = 68%). However, in a subgroup analysis, we found that there was no significant reduction in the PSQI total score for healthy participants over 40 years old (MD = −3.73, 95%CI: [−7.89, 0.42], P = 0.08, I 2 = 98%) and for postmenopausal women (MD = −5.55, 95%CI: [−13.98, −2.89], P = 0.20, I 2 = 98%). Conclusions:Overall, Pilates improved sleep quality but had no significant effect on the use of sleep medication. However, Pilates showed no significant impact on sleep quality for healthy individuals over 40 years old and for postmenopausal women. Well-designed and large-scale RCTs are needed in the future.

“…Poor sleep quality has also been associated with inflammation [ 17 , 18 ], cancer [ 19 ], and an increased mortality risk [ 20 ]. Several risk factors for poor sleep have been proposed, such as age, ethnicity [ 21 ], and sociodemographic status [ 22 ]. Studies have also found associations between worse sleep and a longer dinner-to-bed time [ 21 ], alcohol consumption [ 23 ], and excess macronutrient intake [ 24 ].…”

Studies have explored how vitamin B12 status affects sleep among elders and children, but this remains to be investigated among young adults. We used the Pittsburgh Sleep Quality Index (PSQI) to assess the association between serum vitamin B12 and sleep among female college students in Saudi Arabia. In this cross-sectional study, we enrolled 355 participants (age (years), 20.7 ± 1.5; body mass index, 23.6 kg/m2 ± 5.2) at King Saud University, Riyadh, Saudi Arabia. Fasting blood samples were analyzed regarding the serum vitamin B12 and blood lipids. Anthropometric, socio-demographic, clinical history, stress, physical activity, and dietary data were collected. We assessed the sleep statuses of the participants using the PSQI. Around 72% of the participants were “poor” sleepers (PSQI > 5). Subgroup analysis within the tertiles showed that participants with higher vitamin B12 in the second and third tertiles reported better scores for sleep quality (B ± SE = −12.7 ± 5.6, p = 0.03; B ± SE = −32.7 ± 16.4, p = 0.05, respectively) and also reported a lower use of sleep medication (B ± SE = −21.2 ± 9.9, p = 0.03, in the second tertile only), after adjusting for the waist–hip ratio and stress. However, sleep was not found to be directly associated with either serum vitamin B12 or dietary vitamin B12. In conclusion, the serum vitamin B12 results show that the participants with higher vitamin B12 in the second and third tertiles reported better scores on the sleep quality scale and a lower use of sleep medication. However, no such associations were observed with the overall PSQI. More studies with larger sample sizes are needed to establish a direct relationship between sleep and vitamin B12.
