- STUDY OBJECTIVES: The aim of the study was to investigate how many nights of measurement are needed for a reliable measure of sleep in a working population including adult women and men.METHODS: In all, 54 individuals participated in the study. Sleep was assessed for 7 consecutive nights using actigraphy as an objective measure, and the Karolinska sleep diary for a subjective measure of quality. Using intra-class correlation and the Spearman-Brown formula, calculations of how many nights of measurements were required for a reliable measure were performed. Differences in reliability according to whether or not weekend measurements were included were investigated. Further, the correlation between objectively (actigraphy) measured sleep and subjectively measured sleep quality was studied over the different days of the week.RESULTS/CONCLUSIONS: The results concerning actigraphy sleep measures suggest that data from at least 2 nights are to be recommended when assessing sleep percent and at least 5 nights when assessing sleep efficiency. For actigraphy-measured total sleep time, more than 7 nights are needed. At least 6 nights of measurements are required for a reliable measure of self-reported sleep. Fewer nights (days) are required if measurements include only week nights. Overall, there was a low correlation between the investigated actigraphy sleep parameters and subjective sleep quality, suggesting that the two methods of measurement capture different dimensions of sleep.

- Study Objectives: Insomnia and snoring are common sleep disorders. The aim was to investigate the association of having a combination of insomnia symptoms and snoring with comorbidity and daytime sleepiness. Methods: The study population comprised 25,901 participants (16-75 years, 54.4% women) from 4 Swedish cities, who answered a postal questionnaire that contained questions on snoring, insomnia symptoms (difficulties initiating and/or maintaining sleep and/or early morning awakening), smoking, educational level, and respiratory and nonrespiratory disorders. Results: Snoring was reported by 4,221 (16.2%), while 9,872 (38.1%) reported 1 insomnia symptom. A total of 2,150 (8.3%) participants reported both insomnia symptoms and snoring. The association with hypertension (adjusted odds ratio [OR], 1.4; 95% confidence interval [Cl], 1.2-1.6), chronic obstructive pulmonary disease (adjusted OR, 1.8; 95% CI, 1.3-2.4), asthma (adjusted OR, 1.9; 95% CI, 1.6-2.3), daytime sleepiness (adjusted OR, 7.9; 95% CI, 7.1-8.8), and the use of hypnotics (adjusted OR, 7.5; 95% CI, 6.1-9.1) was highest for the group with both insomnia symptoms and snoring. Conclusions: Participants with both snoring and insomnia run an increased risk of hypertension, chronic obstructive pulmonary disease, asthma, daytime sleepiness, and use of hypnotics. It is important to consider snoring in patients seeking medical assistance for insomnia and, vice versa, in patients with snoring inquiring about insomnia.

- Study Objectives: Chronic rhinosinusitis (CRS) is a common inflammatory disease of the nasal cavity and paranasal sinuses. Associations between CRS and poor sleep quality have been reported. This 10-year follow-up study investigates possible associations between incident CRS and sleep quality. Methods: A questionnaire was sent to 16,500 individuals in Sweden, Norway, Denmark, Iceland and Estonia in 2000. It included questions on airway diseases, age, sex, body mass index, smoking habits, comorbidities, education and sleep quality. In 2010, a second questionnaire was sent to the same individuals, with a response rate of 53%. A subgroup of 5,145 individuals without nasal symptoms in 2000 was studied. Multiple logistic regression was performed to examine associations between CRS (defined according to the European position paper on rhinosinusitis and nasal polyps epidemiological criteria) at follow-up and sleep quality, with adjustment for potential confounders. Individuals with the respective sleep problem at baseline were excluded. Results: Over 10 years, 141 (2.7%) of the individuals without nasal symptoms in 2000 had developed CRS. CRS was associated with difficulties inducing sleep (adjusted odds ratio 2.81 [95% CI 1.67–4.70]), difficulties maintaining sleep (2.07 [1.35–3.18]), early morning awakening (3.03 [1.91–4.81]), insomnia (2.21 [1.46–3.35]), excessive daytime sleepiness (2.85 [1.79–4.55]), and snoring (3.31 [2.07–5.31]). Three insomnia symptoms at baseline increased the risk of CRS at follow-up by 5.00 (1.93–12.99). Conclusions: Incident CRS is associated with impaired sleep quality and excessive daytime sleepiness. Insomnia symptoms may be a risk factor for the development of CRS. © 2019 American Academy of Sleep Medicine. All rights reserved.

Nasal polyposis is a risk factor for nonadherence to CPAP treatment in sleep apnea: the population-based DISCOVERY study
- 2023
-
Ingår i: JOURNAL OF CLINICAL SLEEP MEDICINE. - : American Academy of Sleep Medicine (AASM). - 1550-9389 .- 1550-9397. ; 19:3, s. 573-579

- Study Objectives: The aim was to evaluate nasal polyposis as a risk factor for nonadherence to continuous positive airway pressure (CPAP) treatment in patients with obstructive sleep apnea (OSA). Methods: This was a population-based, longitudinal analysis of patients starting CPAP treatment for OSA in the Swedish quality registry Swedevox between 2010 and 2018. Data were cross-linked with national registries. The impact of nasal polyposis on CPAP adherence was analyzed using uni-and multivariable logistic and linear regression models. Relevant confounders (age, sex, usage of nasal and oral steroids) were identified using a direct acyclic graph. Results: Of 20,521 patients with OSA on CPAP treatment (29.5% females), 331 (1.6%) had a diagnosis of nasal polyposis at baseline. At the 1-year follow-up, nasal polyposis was associated with an increased risk of CPAP usage < 4 hours/night (unadjusted odds ratio [OR] 1.21; 95% confidence interval [CI] 0.95-1.55); adjusted OR 1.38; 95% CI 1.08-1.77). In this group, unadjusted nocturnal mean CPAP usage was 15.4 minutes (95% CI-31.62 to 0.83) shorter and was an adjusted 24.1 minutes (95% CI-40.6 to-7.7) shorter compared with patients with OSA without nasal polyposis. Conclusions: Nasal polyposis is associated with reduced CPAP usage per night. These results highlight the importance of diagnosing nasal polyposis in patients with OSA before the start of CPAP treatment. Treatment of the condition may improve adherence, efficacy, and patient outcomes.

- STUDY OBJECTIVES: Preliminary evidence suggests that the risk of Long COVID is higher among people with pre-existing medical conditions. Based on its proven adjuvant role in immunity, habitual sleep duration may alter the risk for developing Long COVID. The objective of this study was to determine whether the odds of Long COVID are higher amongst those with pre-existing medical conditions, and whether the strength of this association varies by habitual sleep duration.METHODS: Using data from 13,461 respondents from 16 countries who participated in the 2021 survey based International COVID Sleep Study II (ICOSS II), we studied the associations between habitual sleep duration, pre-existing medical conditions, and Long COVID.RESULTS: Of 2,508 individuals who had COVID-19, 61% reported at least one Long COVID symptom. Multivariable logistic regression analysis showed that the risk of having Long COVID was 1.8-fold higher for average-length sleepers (6-9h/night) with pre-existing medical conditions compared to those without pre-existing medical conditions [aOR 1.84 (1.18-2.90), P=0.008]. The risk of Long COVID was 3-fold higher for short sleepers with pre-existing medical conditions [aOR 2.95 (1.04-8.4), P=0.043] and not significantly higher for long sleepers with pre-existing conditions [aOR 2.11 (0.93-4.77), P=0.073] compared to average-length sleepers without pre-existing conditions.CONCLUSIONS: Habitual short nighttime sleep duration exacerbated the risk of Long COVID in individuals with pre-existing conditions. Restoring nighttime sleep to average duration represents a potentially modifiable behavioral factor to lower the odds of Long COVID for at-risk patients.

- Study Objectives: The association of mild obstructive sleep apnea (OSA) with important clinical outcomes remains unclear. We aimed to investigate the association between mild OSA and systemic arterial hypertension (SAH) in the European Sleep Apnea Database cohort. Methods: In a multicenter sample of 4,732 participants, we analyzed the risk of mild OSA (subclassified into 2 groups: mild(AHI) (5-<)(11)(/h) (apnea-hypopnea index [AHI], 5 to <11 events/h) and mild(AHI) (1)(1-<15/h) (AHI, >= 11 to <15 events/h) compared with nonapneic snorers for prevalent SAH after adjustment for relevant confounding factors including sex, age, smoking, obesity, daytime sleepiness, dyslipidemia, chronic obstructive pulmonary disease, type 2 diabetes, and sleep test methodology (polygraphy or polysomnography). Results: SAH prevalence was higher in the mild(AHI) (11-<15/h) OSA group compared with the mild(AHI 5-<11/h) group and nonapneic snorers (52% vs 45% vs 30%; P < .001). Corresponding adjusted odds ratios for SAH were 1.789 (mild(AHI) (11-<15/h); 95% confidence interval [CI], 1.49-2.15) and 1.558 (mild 1.34-1.82), respectively (P < .001). In sensitivity analysis, mild(AHI) (11-<15/h) OSA remained a significant predictor for SAH both in the polygraphy (odds ratio, 1.779; 95% CI, 1.403-2.256; P < .001) and polysomnography groups (odds ratio, 1.424; 95% CI, 1.047-1.939; P = .025). Conclusions: Our data suggest a dose-response relationship between mild OSA and SAH risk, starting from 5 events/h in polygraphy recordings and continuing with a further risk increase in the 11- to <150-events/h range. These findings potentially introduce a challenge to traditional thresholds of OSA severity and may help to stratify participants with OSA according to cardiovascular risk.

- Study objectives: This study aimed to investigate the effect of telemonitoring compared with standard clinic visits on adherence to continuous positive airway pressure (CPAP) treatment after 6 months. In addition, the impact of other factors including CPAP side effects on treatment adherence were assessed.Methods: Consecutive patients (n = 217) who were prescribed CPAP treatment for obstructive sleep apnea were randomized to either telemonitoring or standard-care follow-up. All patients were followed up 6 months after treatment started. Clinical/anthropometric variables, socioeconomical and lifestyle factors, psychological distress, daily function, and personality traits along with CPAP side effects were assessed. Differences between groups were analyzed using 2-sample t-test, chi-square test, or Fisher's exact test. Regression modeling was used to explore associations between dependent and independent variables.Results: There were no differences in CPAP adherence between telemonitoring and standard-care groups after 6 months (53.2% vs 48.7%; P = .54). CPAP side effects such as dry throat (odds ratio = 2.17; 95% confidence interval = 1.25-3.70), increased awakenings (2.50; 1.31-4.76), and exhaling problems (3.70; 1.25-10.1) were independently associated with low CPAP adherence, although these associations were weakened when adding smoking to the model. No other baseline or follow-up factors were associated with CPAP adherence at 6 months.Conclusions: We could not show that telemonitoring follow-up improved adherence levels. Dry throat, increased awakenings, exhaling problems, and smoking had negative effects on CPAP adherence. Preventing side effects and assessing smoking status is therefore of importance when wanting to improve CPAP adherence.

- Study Objectives: To evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on insomnia and other sleep disturbances in health care professionals.Methods: A survey was distributed using social media and organizational emails to Brazilian active health care professionals during the COVID-19 outbreak. We explored potential associated factors including age, sex, occupation, workplace, work hours, income, previous infection with COVID-19, recent/current contact with COVID-19 patients, regional number of incident deaths, anxiety, and burnout. We evaluated new-onset/previous insomnia worsening episodes (primary outcome), new pharmacological treatments, sleep quality, duration, nightmares, and snoring (secondary outcomes).Results: A total of 4,384 health professionals from all regions of the country were included in the analysis (44 ± 12 years, 76% females, 53.8% physicians). Overall, 55.7% were assisting patients with COVID-19, and 9.2% had a previous COVID-19 infection. The primary outcome occurred in 32.9% of respondents inparallel to 13% new pharmacological treatments for insomnia. The sleep quality worsened for 61.4%, while 43.5% and 22.8% reported≥1-hour sleep duration reduction and worsening or new-onset nightmares, respectively. Multivariate analyses showed that age (odds ratio [OR]: 1.008; 95% confidence interval [CI] 1.001–1.015), females (OR: 1.590; 95% CI 1.335–1.900), weight change (decrease: OR: 1.772; 95% CI 1.453–2.161; increase: OR: 1.468; 95% CI 1.249–1.728), prevalent anxiety (OR: 3.414; 95% CI 2.954–3.948), new-onset burnout (OR: 1.761; 95% CI 1.489–2.083), family income reduction > 30% (OR: 1.288; 95% CI 1.069–1.553), and assisting patients with COVID-19 (OR: 1.275; 95% CI 1.081–1.506) were independently associated with new-onset or worsening of previous insomnia episodes.Conclusions: We observed a huge burden of insomnia episodes and other sleep disturbances in health care professionals during the COVID-19 pandemic.
