- Rationale, aims and objectives Continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) has a low long-term adherence. Educational interventions are few and sparsely described regarding content, pedagogical approach and participants' perceptions. The aim was to describe adherence to CPAP treatment, knowledge about OSA/CPAP, as well as OSA patients' perceptions of participating in a group-based programme using problem-based learning (PBL) for CPAP initiation.Educational programme The PBL programme incorporated elements from theories and models concerning motivation and habits. Tutorial groups consisting of four to eight patients met at six sessions during 6 months.Methods A sequential explanatory mixed method design was used on 25 strategically selected patients. Quantitative data regarding, clinical variables, OSA severity, CPAP use, and knowledge were collected at baseline, after 2 weeks and 6 months. Qualitative data regarding patients' perceptions of participation were collected after 6 months by semi-structured interviews using a phenomenographic approach.Results 72% of the patients were adherent to CPAP treatment after 2 weeks and 6 months. All patients improved their baseline knowledge about OSA and CPAP after 2 weeks and sustained it after 6 months. Anxiety and fear, as well as difficulties and needs were motivational factors for participation. Patients described the difficulties of behavioural change, an awareness that improvements do not occur immediately, a realization of the importance of both technical and emotional support and the need for a healthier lifestyle.Conclusion and practice implications A group-based programme using PBL seems to facilitate adaptive and developmental learning and result in acceptable CPAP adherence levels.

- Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side effects are common and long-term adherence low. The Type D (distressed) personality is defined as a combination of negative affectivity and social inhibition. The association of Type D personality with adherence has not been studied in CPAP-treated patients with OSAS. This study aimed to describe the prevalence of Type D personality in OSAS patients with CPAP treatment longer than 6 months and the association with self-reported side effects and adherence. A cross-sectional descriptive design was used. A total of 247 OSAS patients with a mean use of CPAP treatment for 55 months (6-182 months) were included. Data collection was achieved by two questionnaires; the Type D scale 14 (DS14) (Type D personality), SECI (side effects of CPAP), as well as from medical records (clinical variables and objective adherence to CPAP treatment). Type D personality occurred in 30% of the patients with OSAS and significantly (P < 0.05-0.001) increased the perceived frequency and severity of a broad range of side effects. The objective adherence was significantly lower (P < 0.001) for OSAS patients with Type D compared to OSAS patients without Type D, both with regard to a mean use of 4 h per night and 85% of the self-rated sleep time per night. The additional effect of a Type D personality on perceived side effects and adherence to CPAP treatment found in this study could be used by healthcare personnel when evaluating patients waiting for treatment.

- BackgroundHypertension (HT) and obesity have both been linked to obstructive sleep apnoea (OSA). Difficulties have been described in identifying patients with OSA in primary care, causing low referral rates to sleep clinics. Increased knowledge about gender-specific characteristics and symptoms may help to identify patients.AimThe aim was to describe gender differences regarding undiagnosed OSA, self-rated sleep, insomnia and daytime sleepiness in middle-aged primary care patients with HT and different degrees of obesity.MethodsA cross-sectional design was used and 394 patients (52.5% women), mean age 57.8 years (SD 6.7 years), with HT (BP >140/90 mmHg) were included. Clinical examinations, respiratory recordings and self-rated scales regarding OSA symptoms, sleep, insomnia and daytime sleepiness were used. Body mass index (BMI) was classified according to the criteria from the National Institutes of Health.ResultsPre-obesity and obesity classes I and II were seen among 53%, 26% and 8% of the men and 37%, 19% and 14% of the women, respectively. Occurrence of mild, moderate and severe OSA increased significantly across the BMI classes for both genders (p<0.01). Ninety percent of the men and 80% of the women in obesity class II had OSA. Insomnia was prevalent in obese patients. Other clinical variables did not differ between BMI classes or genders.ConclusionThe occurrence of overweight/obesity and OSA was high among both genders. A high BMI might be a convenient clinical marker for healthcare personnel to identify hypertensive patients with possible OSA in need of further evaluation and treatment.

- Background Continuous positive airway treatment (CPAP) is the recommended treatment for patients with obstructive sleep apnea (OSA). Outcome measures often focus on clinical and/or self-rated variables related to the medical condition. However, a brief validated instrument focusing on the whole life situation (i.e., ethos) suitable for clinical practice is missing. The aim of this study was to investigate factorial structure, categorical functioning of the response scale, and differential item functioning across sub-populations of the Ethos Brief Index (EBI) among patients with obstructive sleep apnea (OSA) before and after initiation of continuous positive airway pressure (CPAP). Methods A prospective design, including 193 patients with OSA (68% men, 59.66 years, SD 11.51) from two CPAP clinics, was used. Clinical assessment and overnight respiratory polygraphy were used to diagnose patients. Questionnaires administered before and after 6 months of CPAP treatment included EBI, Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale, and global perceived health (initial item in SF-36). The validity and reliability of the EBI were investigated using Rasch and confirmatory factor analysis models. Measurement invariance, unidimensionality, and differential item functioning across gender groups, Apnea-Hypopnea Index, and ESS groups were assessed. Results The reliability of the EBI was confirmed using composite reliability and Cronbach's alpha. The results supported unidimensionality of the EBI in confirmatory factor analysis and the Rasch model. No differential item functioning was found. A latent profile analysis yielded two profiles of patients with low (n = 42) and high (n = 151) ethos. Patients in the low ethos group were younger and had higher depression scores, lower perceived health, and higher body mass index. Conclusions The EBI is a valid tool with robust psychometric properties suitable for use among patients with OSA before and after treatment with CPAP is initiated. Future studies should focus on its predictive validity.

Sex-Specific Associations Between Self-reported Sleep Duration, Cardiovascular Disease, Hypertension, and Mortality in an Elderly Population
- 2018

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Both short and long sleep durations have been associated to increased mortality. Knowledge about sex-specific differences among elderly regarding associations between sleep duration, cardiovascular health, and mortality is sparse.OBJECTIVE: The aims of this study are to examine the association between self-reported sleep duration and mortality and to investigate whether this association is sex specific and/or moderated by cardiovascular morbidity, and also to explore potential mediators of sleep duration effects on mortality.METHODS: A population-based, observational, cross-sectional design with 6-year follow-up with mortality as primary outcome was conducted. Self-rated sleep duration, clinical examinations, echocardiography, and blood samples (N-terminal fragment of proBNP) were collected. A total of 675 persons (50% women; mean age, 78 years) were divided into short sleepers (≤6 hours; n = 231), normal sleepers (7-8 hours; n = 338), and long sleepers (≥9 hours; n = 61). Data were subjected to principal component analyses. Cardiovascular disease (CVD) and hypertension factors were extracted and used as moderators and as mediators in the regression analyses.RESULTS: During follow-up, 55 short sleepers (24%), 68 normal sleepers (20%), and 21 long sleepers (34%) died. Mediator analyses showed that long sleep was associated with mortality in men (hazard ratio [HR], 1.8; P = .049), independently of CVD and hypertension. In men with short sleep, CVD acted as a moderator of the association with mortality (HR, 4.1; P = .025). However, when using N-terminal fragment of proBNP, this effect became nonsignificant (HR, 3.1; P = .06). In woman, a trend to moderation involving the hypertension factor and short sleep was found (HR, 4.6; P = .09).CONCLUSION: Short and long sleep duration may be seen as risk markers, particularly among older men with cardiovascular morbidity.

- BackgroundObstructive sleep apnoea (OSA) has been linked to hypertension in sleep clinic populations, but little is known about the symptom profile of undiagnosed OSA in hypertensive outpatients in primary care.AimTo explore characteristics associated with undiagnosed OSA in hypertensive primary care patients.MethodsCross-sectional design, including 411 consecutive patients (52% women), mean age 57.9 years (standard deviation [SD] 5.9 years), with diagnosed hypertension (blood pressure >140/90 mmHg) fromfour primary care centres. All subjects underwent a full-night, home-based, respiratory recording to establish the presence and severity of OSA. Clinical variables, medication and comorbidities, as well as data from self-rating scales regarding symptoms/characteristics, insomnia, excessive daytime sleepiness, depressive symptoms and health were collected during a clinical examination. Factor analyses and structural equation modelling (SEM) were used to explore the relationships between selfrated symptoms, clinical characteristics and objectively verified diagnosis of OSA.Main outcomeMeasures symptom profile of undiagnosed OSA (as measured by the Apnoea/ Hypopnoea Index [AHI]) in hypertensive outpatients in primary care.ResultsFifty-nine percent of the patients had an AHI _ 5/hour indicating OSA. An exploratory factor analysis based on 19 variables yielded a six-factor model (anthropometrics, blood pressure, OSA-related symptoms, comorbidity, health complaints and physical activity) explaining 58% of the variance. SEM analyses showed strong significant associations between anthropometrics (body mass index, neck circumference, waist circumference) (0.45), OSA-related symptoms (snoring, witnessed apnoeas, dry mouth) (0.47) and AHI. No direct effects of OSA on comorbidities, blood pressure, dyssomnia or self-rated health were observed.ConclusionOSA was highly prevalent and was directly associated with anthropometrics and OSArelated symptoms (snoring, witnessed apnoeas and dry mouth in the morning). When meeting patients with hypertension, these characteristics could be used by general practitioners to identify patients who are in need of referral to a sleep clinic for OSA evaluation.

- Adherence to continuous positive airway pressure (CPAP) treatment tends to be low. Brief validated instruments focusing on shared decision making have not been used in a CPAP context. The aim was to investigate factorial structure, categorical functioning of the response scale and differential item functioning across sub-populations of the CollaboRATE and Sure questionnaires among patients with obstructive sleep apnea (OSA) before CPAP treatment is initiated. A prospective design, including 193 objectively diagnosed (polygraphy) OSA patients (68% men, 59.7 years, SD 11.5) from two CPAP clinics was used. Data were collected with the following questionnaires; Sure, CollaboRATE, Attitudes to CPAP Inventory, Epworth sleepiness scale, minimal insomnia symptoms scale, and hospital anxiety and depression scale. Objective CPAP use was collected after 6 months; 49% demonstrated decisional conflict on SURE and 51% scored low levels of shared decision making on CollaboRATE. Unidimensionality was found for both CollaboRATE (one factor explaining 57.4%) and SURE (one factor explaining 53.7%), as well as local independence. Differential item functioning showed both to be invariant across both male and female patients. Internal consistency (Cronbach's alpha 0.83) and composite reliability (0.89) were good. Latent class analyses showed that patients with low decisional conflict and high shared decision making were more adherent to CPAP treatment. CollaboRATE and SURE provided good validity and reliability scores to measure shared decision making and decisional conflict in relation to CPAP treatment. The questionnaires can be used by healthcare personnel as a tool to simplify the assessment of shared decision making.

Forskningsöversikt (refereegranskat)abstract
- This systematic review, meta-analysis and meta-regression assessed the prevalence of restless legs syndrome (RLS) in the general adult population. Studies identified in Scopus, PubMed, Web of Science, and PsycInfo between January 2000 and February 2022 were included if they used a case–control or cross-sectional design and reported data regarding the prevalence of RLS. The protocol was pre-registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42022300709). A total of 97 studies including 483,079 participants from 33 different countries met the eligibility criteria. The Newcastle Ottawa Scale was used to evaluate the methodological quality, and the fill-and-trim method was used to correct probable publication bias, while the jack-knife method was performed to assess small study effect. The corrected overall pooled prevalence of RLS was 3% (95% confidence interval [CI] 1.4%–3.8%). The pooled prevalence of RLS syndrome was affected by methodological quality (no data from non-respondents in the included studies), gender (higher among women), study design (lower prevalence in case–control versus cohort and cross-sectional studies). The figures for corrected pooled prevalence among men, women, alcohol consumers and smokers were 2.8% (95% CI 2%–3.7%); 4.7% (95% CI 3.2%–6.3%); 1.4% (95% CI 0%–4.2%); and 2.7% (95% CI 0%–5.3%), respectively. The prevalence among male and female participants was lower in community-based versus non-community-based studies. Moreover, the prevalence was higher in developed versus developing countries and among elders versus adults. In conclusion, RLS is a common disorder in the general adult population, with a higher prevalence in women; however, prevalence data are affected by study design and quality.
