Population-based analysis of sociodemographic predictors, health-related quality of life and health service use associated with obstructive sleep apnoea and insomnia in Australia

Efficacy of Mindfulness Meditation on Patients With Stroke With Concurrent Coronary Heart Disease: A Randomised Controlled Trial

OBJECTIVE

This study aimed to investigate the efficacy of mindfulness meditation on sleep quality and negative emotions in patients with stroke with concurrent coronary heart disease.

METHODS

This study was a randomised controlled trial. A total of 72 patients with stroke with concurrent coronary heart disease were randomly divided into an observation group and a control group, with 36 patients in each group. The control group received routine treatment plus eszopiclone tablets at a dosage of 3 mg once daily. The observation group received mindfulness meditation in addition to the treatment given to the control group. The Pittsburgh Sleep Quality Index was used to assess sleep status, the Self-Rating Anxiety Scale and Self-Rating Depression Scale were used to assess depression and anxiety, and the Fugl-Meyer Assessment was used to assess motor function. All participants in both groups received a 6-week intervention.

RESULTS

Pairwise comparisons revealed that the observation group had better outcomes in sleep quality, sleep onset latency, sleep duration, sleep efficiency, sleep disturbances, daytime function and total scores at both 6 and 12 weeks compared with the control group (p < 0.05). After 12 weeks of intervention, compared with the control group, the total score of sleep quality improved more significantly (9.22 ± 2.35/6.26 ± 2.47). Additionally, different treatment methods had varying effects on anxiety scores, depression scores and motor function scores between the two groups (p < 0.001). Further comparisons showed that the observation group had lower anxiety and depression scores and higher motor function scores at both 6 and 12 weeks compared with the control group (p < 0.05).

CONCLUSION

Mindfulness meditation can effectively improve sleep quality and reduce negative emotions in patients with stroke with concurrent coronary heart disease, as well as promote the recovery of limb functions.

The preventable productivity burden of sleep apnea in Australia: a lifetime modelling study

Obstructive sleep apnea (OSA) is a common disorder. OSA is associated with cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM) and depression, among other comorbidities. We aim to determine the productivity burden of OSA in Australia using productivity-adjusted life-years (PALYs). Using life table modelling, we built a multistate Markov model to estimate the impact of moderate to severe OSA on the whole working-age Australian population in 2021 (aged 20-65 years) with OSA until retirement (aged 66 years). The model also captured the impact of OSA on CVD, T2DM, depression, and vehicle-related accidents. Data for OSA and comorbidities and Australian specific labour data, were extracted from published sources. A second cohort was then modelled to test the effect of a hypothetical intervention, assuming a 10% reduction in OSA prevalence and a 10% reduction in comorbidities in patients with OSA. The primary outcome of interest were PALYs accrued. All outcomes were discounted 5% annually. Over a lifetime, the Australian population with OSA accrued 193,713,441 years of life lived and 182,737,644 PALYs. A reduction of 10% in OSA prevalence and comorbidities would result in 45,401 extra years of life lived and 150,950 extra PALYs. This resulted in more than AU$25 billion of gained gross domestic product over the lifetime of the working population. Our study highlights the substantial burden of OSA on the Australian population and the need to tailor interventions at the population level to reduce the health and economic impacts.

A systematic review with meta-analyses of the relationship between recurrent binge eating and sleep parameters

BACKGROUND

Sleep problems are known to compound the negative effects of other health issues, such as eating disorders and the associated behavior of binge eating. Previous studies suggested associations between binge eating and sleep problems, but the strength of the relationship is unknown.

METHODS

We conducted a systematic review with meta-analyses examining the relationship between binge eating and sleep parameters. We searched for studies in Scopus, PubMed, and PsycInfo. The quality of evidence, including risk of bias, was assessed with adaptations of the Newcastle-Ottawa Scale and the Joanna Briggs Institute Critical Appraisal Checklist for Quasi-Experimental Studies, depending on study design. Data was synthesized as the difference in sleep between people who did or did not have binge eating.

RESULTS

Thirty-one reports of studies met our eligibility criteria. Results are presented in 12 meta-analyses. In the 7 reports of studies (with 4448 participants) that assessed poor overall sleep quality, we found poorer overall sleep quality in people with binge eating compared to people without binge eating, with a standardized mean difference of 0.77 (95% confidence interval [CI] 0.61-0.92; P < 0.001), which is a large effect size. In addition, we found evidence that people with binge eating had significantly greater hypersomnia/daytime sleepiness (7 reports of studies with 4370 participants), insomnia (5 reports of studies with 12,733 participants), and difficulty falling asleep (3 reports of studies with 4089 participants) compared to people without binge eating, with moderate effect sizes (standardized mean differences of 0.57-0.66).

CONCLUSIONS

People with binge eating exhibit poorer overall sleep quality compared to people without binge eating, and may also exhibit greater hypersomnia/daytime sleepiness, insomnia, and difficulty falling asleep. It is recommended that healthcare professionals routinely screen for poor overall sleep quality when treating people with binge eating-and address sleep difficulties when present.

Long-term benzodiazepines and z-drug prescribing in Australian general practice between 2011 and 2018: A national study

Despite reducing benzodiazepine prescribing, benzodiazepine-involving deaths have substantially increased in Australia. This study aimed to explore patterns in long-term prescribing of medications (benzodiazepine and z-drugs [BZD]) used for sleep-issues/insomnia in Australia to better understand these changes. Open cohort study using de-identified electronic health records of 1 414 593 adult patients regularly attending 404 Australian general practices from 2011 to 2018 (MedicineInsight). We used logistic regression adjusted for patient and practice characteristics to; (1) estimate long-term BZD prescribing prevalence (≥3 prescriptions in 6 months) and the associated sociodemographic factors, and (2) Poisson regression to compute annual changes in prescribing rates. Long-term BZD prescribing changed from 4.4% in 2011 to 5.8% in 2015, remaining relatively stable until 2018 (annual increase +2.5% [95% CI +2.0%;+3.0%]). Long-term BZD prescribing in any year was up to six times more likely in elderly rather than in younger patients and 30%-43% more prevalent in females, or patients living in or attending a practice located in more disadvantaged areas. The increase was more pronounced among males, adults aged 35-49 years, and individuals living in advantaged areas. The median duration among incident cases decreased from 1183 to 322 days between 2011 and 2017, and was up to 197 days longer among elderly females than males. Despite a slight increase and recent stability in long-term BZD prescribing, the higher rates and durations among elderly patients, women, or those living in more disadvantaged areas are concerning and highlights the need for interventions that reduce the potential harms of long-term BZD use in vulnerable groups.
