COVID-19 and Sleep Disturbances: A Literature Review of Clinical Evidence

Respiratory function and sleep parameters in adults following recovery from acute COVID-19

The impact of COVID-19 on lung function and sleep in otherwise healthy individuals has been subject to a limited number of studies. The aim of this study was to investigate the effect of COVID-19 on pulmonary function and sleep in adults. Participants, 50-85 years old, who had recovered from COVID-19 (COVID-19 group: n = 48) and those without history of COVID-19 (control group: n = 28) underwent pulmonary function assessment (Forced Vital Capacity, FVC, and Slow Vital Capacity, SVC) using spirometry. Sleep and circadian variables were measured objectively with wrist-worn actigraphy for seven days. Subjective sleep of participants was assessed using the Pittsburgh Sleep Quality Index (PSQI). There were no significant differences in age (60 ± 6 vs 62 ± 6 years), BMI (26.30 ± 4.25 vs 26.48 ± 3.60 kg/m2), or pulmonary function (FVC, 4.02 ± 1.04 vs 3.80 ± 0.98 L, p = 0.36; and SVC, 3.82 ± 1.09 vs 3.89 ± 0.92 L, p = 0.76) between COVID-19 and control groups. The COVID-19 group had significantly reduced sleep efficiency (0.87 ± 0.04 vs 0.91 ± 0.04, p < 0.01), increased sleep disturbance (awakenings, 1.70 ± 1.02 vs 1.15 ± 1.15, p < 0.01; and wakefulness after sleep onset, 35:05 ± 25:37 vs 20:02 ± 12:48 min, p = 0.01) and PSQI score (5.19 ± 2.88 vs 3.93 ± 2.89, p = 0.01), compared to the control group. Individuals with history of COVID-19 demonstrate reduced sleep quality compared to a non-COVID-19 control group.

Rising Prevalence of Urinary Incontinence and Nocturia Amid the COVID-19 Pandemic

BACKGROUND

Urinary incontinence (UI) and nocturia are common lower urinary tract symptoms (LUTS) that significantly affect quality of life. The COVID-19 pandemic has introduced behavioral, psychological, and physiological disruptions that may have exacerbated the prevalence of these conditions. Additionally, these changes may also be influenced by long-term sequelae of COVID-19 infection or other concurrent factors. However, large-scale investigations into these trends are limited.

METHODS

Data from the National Health and Nutrition Examination Survey (NHANES) between 2017 and 2023 were used to analyze the prevalence of LUTS, including stress urinary incontinence (SUI), urgency urinary incontinence (UUI), mixed urinary incontinence (MUI), and nocturia, before (2017-2020) and during the pandemic (2021-2023). Age-adjusted prevalence trends were analyzed overall and by sex and race/ethnicity. Sensitivity analysis included data from 2013 to 2016 to differentiate natural trends from pandemic-related impacts.

RESULTS

The prevalence of SUI, UUI, MUI, and nocturia significantly increased during the pandemic compared to pre-pandemic levels (p < 0.0001). SUI rose from 24.89% to 29.65%, UUI from 20.80% to 28.65%, MUI from 9.17% to 16.83%, and nocturia from 26.96% to 34.78%. These trends were consistent across sexes and racial groups. Sensitivity analysis confirmed that these increases exceeded natural trends, suggesting a potential pandemic-related effect.

CONCLUSION

This study reveals a significant rise in the prevalence of LUTS, including SUI, UUI, MUI, and nocturia, during the COVID-19 pandemic. Further research is needed to determine whether these changes stem from the direct physiological effects of COVID-19 infection or are influenced by broader pandemic-related factors such as lifestyle changes, healthcare disruptions, and psychological stress.

Lessons learned from the lived experiences of people living with obesity during the first COVID-19 lockdown in the United Kingdom

BACKGROUND

Quantitative studies have shown that people living with obesity experienced deteriorations in mental health and health-related behaviours during the first UK's Coronavirus Disease-2019 (COVID-19) lockdown. However, there is a lack of qualitative research exploring their lived experiences during this period.

METHODS

Thematic analysis of large-scale free-text survey data was conducted to understand the challenges faced by adults with obesity during the first UK's COVID-19 lockdown.

RESULTS

Among 543 participants, 467 (86%) responded to the free text questions. The majority were female (87.8%), with a mean age of 51.6 (SD 9.9) years. Of these, 65.3% has a body mass index ≥40 kg/m2, and 57.7% were not enroled in weight management services. Five overarching themes and 10 sub-themes were identified with the five key themes being (1) increased fear and anxiety, (2) the impact of obesity being classified as 'high risk', (3) disruption in weight management services, (4) the impact on health-related behaviours, and (5) the adverse impact on mental health. Participants expressed fear of contracting COVID-19 and concerns about weight gain. UK Government messages linking obesity with severe COVID-19 complications exacerbated feelings of shame and stigma. The reduced provision of weight management services caused further health concerns, highlighting the need for digital health technologies for continued support. Participants reported changes in shopping, diet, physical activity, and sleep patterns, leading to deteriorated mental health.

CONCLUSION

People living with obesity experienced distinct challenges during the first COVID-19 lockdown, affecting their ability to practice and maintain health-related behaviours.

The impact of COVID-19 pandemic on sleep duration and mental health among middle school students: a 3-year cross-sectional survey

Background

Since the outbreak of COVID-19 in late 2019, and until the Chinese government downgraded the pandemic control measures to Category B management in January 2023, various epidemic prevention measures were implemented across regions based on the local spread of the virus. Correspondingly, educational formats shifted between online and offline teaching according to the pandemic situation. Changes in daily life and teaching methods, along with the high initial mortality rate of COVID-19, have had varying degrees of negative impact on the mental health (MH) of adolescents.

Purposes

This study aimed to explore the impact of the COVID-19 pandemic status on the sleep duration (SD) and MH of adolescents, investigate the relationship between SD and MH in middle school students, and evaluate the protective effect of SD on MH.

Methods

Using a convenient sampling method, 6 junior high schools and 3 senior high schools in Guiyang City, China, were selected. Random samples from two classes per grade in each school were chosen for the survey. The study was conducted annually for three consecutive years using the Mental Health Inventory of Middle-school students (MMHI-60) scale and a self-designed questionnaire. Data were analyzed using IBM SPSS version 26.0 software, employing ANOVA, cross-tabulation, and generalized linear models to examine the relationship between SD and MH scores.

Results

The SD and MH scores of middle school students in 2021, 2022, and 2023 were 436.41 ± 71.21 min/day, 423.69 ± 61.71 min/day, and 445.26 ± 65.04 min/day (F = 41.44, p < 0.001), 1.72 ± 0.63, 1.87 ± 0.73, and 1.79 ± 0.67 (F = 18.31, p < 0.001). The SD compliance rates were 34.1%, 23.9%, and 33.2%, and the MH problem detection rates were 27.9%, 36.4%, and 33.4%, respectively; there is a significant correlation between SD and MH scores among middle school students (P < 0.001); the protective effects of SD compliance on MH were 1.859 times, 2.156 times, and 1.516 times higher than those of SD non-compliance (all p < 0.001).

Conclusion

Meeting the SD standard is a protective factor for adolescent MH. The COVID-19 pandemic and its control measures have had a severe and long-term negative impact on both SD and MH in middle school students, with differences observed between genders and academic levels. The greater the severity of the pandemic and the stricter the control measures, the more significant the negative impact on SD and MH etc.

Sleep Quality Among Patients and Healthcare Providers in the Primary Healthcare Setting

Background/Objectives: As adults spend about 30% of each day asleep, having a sleep disorder can negatively affect their functioning. The study objective was to determine the factors that influence sleep quality among patients and healthcare providers in the primary healthcare setting. Methods: This study included respondents of both sexes aged 18-90 years, comprising outpatients and the healthcare providers working in the General Medicine Service at the "Liman" Department of the "Novi Sad" Health Center in Novi Sad, Republic of Serbia. Demographic data along with factors related to lifestyle and sleep habits were collected using a demographic questionnaire specifically designed for this research. The standardized Pittsburgh Sleep Quality Questionnaire, Serbian version (PSQI), was used to assess sleep quality. Results: The study sample comprised 92 respondents (42 healthcare providers and 50 patients), 73.9% of whom were female, with an average age of 50.0 years. Although 50% of healthcare providers reported sleeping only 3-6 h the previous night, according to the PSQI results, patients had lower overall sleep quality (54.0% vs. 33.3%; p = 0.046) and achieved lower scores in the DISTB (sleep disturbances, p = 0.001), SLPQUAL (subjective sleep quality, p = 0.013) and MEDS (use of sleeping medication, p = 0.003) PSQI domains. Conclusions: Sleep quality is impaired in more than half of patients and more than a third of healthcare providers. By detecting and acting on the factors in the home and work environment that affect quality of sleep, and by changing lifestyle habits, sleep quality in adults can be improved.

Latent profiles and determinants of postoperative sleep quality in elective surgery patients

It is crucial to determine the potential subgroups of sleep disturbances in patients undergoing elective surgery based on the importance of symptom clusters and individual characteristics in order to develop targeted symptom management plans. This study explored the potential categories of postoperative sleep disturbances in patients undergoing elective surgery through latent profile analysis, and explored the influencing factors of each category. A total of 400 eligible elective surgery patients were included in the analysis, and three potential subgroups were identified: mild sleep disturbance group (c1 = 140,35.0%), moderate sleep sleep disturbance group (c2 = 177,44.2%), and severe sleep disturbance group (c3 = 83,20.8%). It was found that the higher the BMI, the greater the probability of patients belonging to the moderate sleep disturbance group (OR = 1.114, P = 0.002) and the severe sleep disturbance group (OR = 1.258, P < 0.001),the longer the duration of anesthesia the greater the likelihood of patients belonging to the severe sleep disturbance group (OR = 1.004,P = 0.011), the greater the pain the greater the probability of patients belonging to the moderate sleep disturbance group (OR = 1.590,P < 0.001) and severe sleep disturbance group (OR = 1.785,P < 0.001), and the higher the anxiety level the greater the probability that patients were in the moderate sleep disturbance group (OR = 1.135,P = 0.007) and severe sleep disturbance group (OR = 1.261,P < 0.001).

A longitudinal study to COVID-19 infection among university students: Physical fitness changes and psychological responses

Background

The impact of COVID-19 infection on physical and mental health of young adults remains unclear. This study aimed to investigate the changes in the physical fitness three months after recovering from acute COVID-19 infection, and examine if the infection could also influence the mental health of university students.

Methods

A total of 460 university students (mean age 18.9 ± 1.3 years, with 30 males and 27 females uninfected with COVID-19) volunteered for the study. Participants underwent a fitness test initially, followed by another physical fitness test and a mental health assessment three months after the infection of COVID-19. Physical fitness tests included body composition, flexibility, cardiorespiratory fitness, muscle strength, and muscular endurance. Mental health was assessed using the Depression-Anxiety-Stress Self-Assessment Scale (DASS-21), the Pittsburgh Sleep Quality Inventory (PSQI), and the Post-Traumatic Stress Disorder Self-Assessment Scale (PTSD).

Results

Three months after acute COVID-19 infection, the physical performance of university students had decreased compared to pre-infection levels by approximate 3-15 % (p < 0.05). Regarding mental health, a notable difference was observed in sleep quality, with the positive group scoring 19 % higher than the negative group (p < .05, d = .44). Sex (β = .164, p < .05), previous infection (β = .277, p = .019) and anxiety (β = .373, p = .002) were predictive of PSQI scores, accounting for 37.5 % of the variance.

Conclusions

All participants experienced a decline in physical fitness compared to their pre-infection levels, regardless of infection status. Those who had been infected exhibited poorer sleep quality compared to their non-infected peers. Prior COVID-19 infection and higher anxiety levels may contribute to poorer sleep quality.

Nurses' Sleep Quality and Its Influencing Factors During the First Explosive COVID-19 Outbreak in Zhejiang, China, After the Relaxation of Epidemic Prevention and Control Measures: A Multicentre Cross-Sectional Study

AIM

To investigate the sleep quality and its influencing factors among nurses in hospitals in Zhejiang, China, during the first explosive COVID-19 outbreak following the relaxation of prevention and control measures.

DESIGN

A multicentre cross-sectional study.

METHODS

Between 10 January and 20 January 2023-approximately 1 month after the policy was loosened-a total of 573 nurses from tertiary and community hospitals in Zhejiang participated in an online, self-administered survey. The participants were recruited using convenience sampling, and the survey was distributed via the WeChat platform. The survey included a general information form; the Self-Rating Scale of Sleep (SRSS); the Depression, Anxiety, and Stress Scale-21 (DASS-21); the Perceived Social Support Scale (PSSS); and the Brief Resilience Scale (BRS). Data analysis was conducted using SPSS version 26.0. Statistical methods employed included t-tests, one-way analysis of variance (ANOVA), chi-square tests and Mann-Whitney U-tests for comparisons between groups. Pearson correlation coefficients were calculated to analyse the relationship between the SRSS score and the DASS-21, PSSS and BRS scores. A multiple linear stepwise regression analysis was conducted to determine the independent influencing factors of sleep quality.

RESULTS

More than 90% of the nurses were infected with COVID-19, and 60.6% had sleep disorders. The regression analysis revealed that anxiety, the BRS score, comorbidities, hospital grade, clinical front-line, age and COVID-19 infection independently predicted sleep quality. The scores for several SRSS items were higher than the Chinese norm, especially for the nurses in tertiary hospitals.

Use of integrative and complementary practices in Brazil during the COVID-19 pandemic

The SARS-CoV-2 coronavirus pandemic posed an unprecedented challenge to global health. In the context of an overwhelmed healthcare system and the rising demand for alternative strategies to manage stress and anxiety, this study aims to investigate and analyze the use of Integrative and Complementary Practices (ICP) in Brazil during the COVID-19 pandemic, emphasizing their importance in promoting health and well-being. We conducted a cross-sectional study among n = 12,136 Brazilian adults predominantly female, white, under 40 years of age and with a predominantly higher education level between August 24 and December 16, 2020, to assess the use of ICP. An online questionnaire was applied, with questions validated in previous health surveys. The sampling method employed was 'virtual snowball,' post-stratification procedures were used to consider the Brazilian regions, gender, age group, and educational level. The reported prevalence of ICP use was 61.8%, with meditation (28.2%), Reiki (21.7%), herbal medicine (28.2%), and aromatherapy (16.5%) being the most utilized practices. ICPs were more frequently adopted by females, older age groups, individuals with health insurance, and those who practiced social distancing. Health promotion and well-being were the primary reasons for engaging in ICP. The high adherence to ICP during the COVID-19 pandemic in Brazil reflects the population's search for therapeutic alternatives focused on the well-being and mental health. The utilization of ICP indicates the need to integrate these practices into healthcare systems, considering their potential to complement conventional treatment, especially in times of crisis. Public health policies should recognize and facilitate access to such practices to reduce inequities and promote integrative health. This study contributes to the understanding of the role of ICP in a public health crisis, encouraging further investigation into the potential inclusion of these practices in the healthcare system.

Quality of sleep after COVID-19 infection: a cross-sectional study in the Southern Italy

Introduction

This study investigated the quality of sleep in a sample of individuals from Southern Italy after the major waves of the COVID-19 pandemic, with the aim of evaluating how sleep patterns changed.

Methods

A cross-sectional study was conducted between March 2022 and January 2023 and involved adults who had a COVID-19 infection, who were invited to complete a self-administered online questionnaire.

Results

A total of 408 individuals participated in the survey. Overall, 66.4% had a reduction in social relations; 72.1% had an increase in the use of social media; and 86%, 77.2%, and 71.1% reported an extremely severe level of anxiety, stress, and depression, respectively. Almost all of the respondents had a Pittsburgh Sleep Quality Index score (PSQI) ≥5, indicating poor sleep quality. Subjects with a severe or extremely severe depression score, a severe or extremely severe stress score, who had a job, and who had someone close who died because of a COVID-19 infection were more likely to have a high PSQI global score. The use of sleep medication in the past months was significantly higher in those who were older, who had a job, who had a COVID-19 infection in the first and second waves, who had someone close who died from COVID-19, and who did not have changes in social relationships during the pandemic. Moreover, participants with severe or extremely severe depression scores, with severe or extremely severe stress scores, who were women, and who were older had troubles staying awake while engaging in social activities during the past month.

Conclusion

The results bring to light the high prevalence of poor sleep quality among individuals who were infected with SARS-CoV-2. Future research is needed to understand whether these disturbances are still present in the endemic period and whether it is necessary to investigate further determinants that have affected and/or are affecting sleep quality.

Device-assessed physical activity and sleep quality of post-COVID patients undergoing a rehabilitation program

BACKGROUND

An infection with SARS-CoV-2 can lead to persistent symptoms more than three months after the acute infection and has also an impact on patients' physical activity behaviour and sleep quality. There is evidence, that inpatient post-COVID rehabilitation can improve physical capacity and mental health impairments, but less is known about the change in physical behaviour and sleep quality.

METHODS

This longitudinal observational study used accelerometery to assess the level of physical activity and sleep quality before and after an inpatient rehabilitation program. The study sample consists of 100 post-COVID patients who acquired COVID-19 in the workplace. Group differences related to sex, age, COVID-19 severity, and pre-existing diseases were also analysed.

RESULTS

Level of physical activity and sleep quality didn't increase after rehabilitation. Overall, there is a high extent of inactivity time and poor sleep quality at both measurement points. Regarding group differences, male patients showed a significantly higher inactivity time before rehabilitation, and younger patients (< 55 years) spend significant more time in vigorous physical activity than older patients. Post-COVID patients with pre-existing cardiovascular, respiratory, and metabolic disease show slightly less physical activity than post-COVID patients without these comorbidities. Female patients and younger patients showed better sleep quality in some sleep parameters at both measurement points. However, no differences could be detected related to COVID-19 severity.

CONCLUSIONS

Ongoing strategies should be implemented to address the high amount of inactivity time and the poor sleep quality in post-COVID patients.

Stress at Work and Well-being Before and During the COVID-19 Pandemic: A 1-Year Longitudinal Study in Switzerland

OBJECTIVE

The aim of the study is to analyze the development of conditions at work and health-related variables (notably exhaustion) in Switzerland longitudinally before and during the COVID-19 pandemic.

METHODS

Questionnaire data were collected from a population-based sample of 1,553 employees in February 2020 and 1 year later. Health and well-being associated with ( a ) working conditions in general and ( b ) COVID-19-specific predictors such as worries about being infected and conditions for working at home were analyzed using analysis of (co)variance and multiple regression.

RESULTS

Conditions at work and well-being were stable overall, even indicating slight improvements, notably for men compared with women. Both an index representing stressors and resources at work in general (Job Stress Index) and a COVID-19-related demand index showed consistent effects on health and the effect of COVID-19-related demands was stronger if the Job Stress Index deteriorated than when it improved.
