A school-based health and mindfulness curriculum improves children's objectively measured sleep: a prospective observational cohort study

Sleep hygiene measures combined with mindfulness meditation in the management of sleep bruxism in children: A randomized controlled clinical trial

BACKGROUND

Sleep hygiene measures and meditation may reduce stress and improve sleep quality, but their effect on the occurrence of sleep bruxism in children has not yet been investigated.

AIM

To explore the effects of sleep hygiene measures combined with mindfulness meditation (relaxation audio) in the management of probable sleep bruxism (SB) in children.

DESIGN

This clinical trial (no. NCT04501237) randomized 36 children with 3-8 years of age. Probable SB detection was performed according to the criteria established by the International Consensus on The Assessment of Bruxism-2018. Intervention group was instructed to practice sleep hygiene measures and mindfulness meditation (i.e., the use of a digital app to broadcast audio relaxation) each night before bedtime for 5 weeks; control group did not receive guidance for therapies. Parents completed a bruxism diary for 5 weeks, and the outcome was the number of SB episodes-day reported in the week (ranging from 0 to 7) in each period. A multilevel mixed-effects Poisson regression model was performed.

RESULTS

A total of 32 children (mean age: 6.1 years) completed the study. The children who received the therapies related to sleep hygiene measures and mindfulness meditation had a reduction in the SB incidence rate ratio (IRR) of 46% (IRR = 0.54 [Confidence Interval 95%, 0.45-0.65]) during a 5-week observation period. The sensitivity analyses did not show relevant changes in the measure of the effect.

CONCLUSION

Sleep hygiene measures combined with mindfulness meditation reduced the SB in children.

Program evaluation of a school-based mental health and wellness curriculum featuring yoga and mindfulness

BACKGROUND

Interest in the effectiveness of mindfulness-based interventions such as yoga in primary schools has grown. Evidence shows promise, as youth who engage in yoga to promote mindfulness show improved coping skills, increased socio-emotional competence and prosocial skills, academic performance, attention span, and ability to deal with stress.

OBJECTIVE

This study reports the results of a program evaluation of a universal health and wellness curriculum, Pure Power, designed to teach youth yoga techniques, mindfulness, and emotion regulation.

METHODS

A non-randomized comparison design examined outcomes among participants from schools that completed the intervention with highest fidelity of implementation (n = 461) and from students in matched comparison schools (n = 420). Standard measures of coping, emotion regulation and emotion dysregulation, spelling, and math achievement were collected.

RESULTS

Analyses suggest the youth in the intervention schools demonstrated relative improvement on measures of emotion regulation, spelling, and math.

CONCLUSIONS

Challenges in implementation in real-life settings are vital to identify. The data provide some real-world evidence for the effectiveness of a universal health and wellness curriculum on emotion regulation and positive academic outcomes. Training school staff to deliver the intervention may foster implementation. Future research should test the effectiveness of who delivers the intervention; for example, teacher-delivered groups vs. other wellness personnel.

Sleep quality and associated factors among university students in Africa: a systematic review and meta-analysis study

Background

Poor sleep quality significantly impacts academic performance in university students. However, inconsistent and inconclusive results were found in a study on sleep among university students in several African nations. Therefore, this study aimed to estimate the pooled prevalence and associated factors of poor sleep quality among university students in Africa.

Methods

The databases PubMed, Scopus, Cochrane Library, Science Direct, African Journal Online, and Google Scholar were searched to identify articles. A total of 35 primary articles from 11 African countries were assessed and included in this systematic review and meta-analysis. Data were extracted by using a Microsoft Excel spreadsheet and exported to STATA version 14 for analysis. The I2 test was used to assess the statistical heterogeneity. A random effect meta-analysis model was employed with 95% confidence intervals. Funnel plots analysis and Egger regression tests were used to check the presence of publication bias. A subgroup analysis and a sensitivity analysis were done.

Results

A total of 16,275 study participants from 35 studies were included in this meta-analysis and systematic review. The overall pooled prevalence of poor sleep quality among university students in Africa was 63.31% (95% CI: 56.91-65.71) I2 = 97.2. The subgroup analysis shows that the combined prevalence of poor sleep quality in East, North, West, and South Africa were 61.31 (95% CI: 56.91-65.71), 62.23 (95% CI: 54.07-70.39), 54.43 (95% CI: 47.39-61.48), and 69.59 (95% CI: 50.39-88.80) respectively. Being stressed (AOR= 2.39; 95% CI: 1.63 to 3.51), second academic year (AOR= 3.10; 95% CI: 2.30 to 4.19), use of the electronic device at bedtime (AOR= 3.97 95% CI: 2.38 to 6.61)) and having a comorbid chronic illness (AOR = 2.71; 95% CI: 1.08, 6.82) were factors significantly associated with poor sleep quality.

Conclusion

This study shows that there is a high prevalence of poor sleep quality among university students in Africa. Being stressed, in the second year, using electronic devices at bedtime, and having chronic illness were factors associated with poor sleep quality. Therefore, addressing contributing factors and implementing routine screenings are essential to reduce the burden of poor sleep quality.

Mindfulness as an Adjunct or Alternative to CBT-I

Mindfulness-based interventions (MBIs) are programs that teach mindfulness concepts through guided meditation and self-regulation practices. MBIs have been found to improve sleep and reduce cognitive arousal, which are central to the development and perpetuation of insomnia. In this article, we review theoretic frameworks and clinical trial effectiveness data supporting MBIs for insomnia. Based on this review, we provide suggestions for using MBIs as an adjunct or alternative treatment option to CBT-I with regard to how, when, and for whom. We conclude with an agenda for future directions that can clarify the use of mindfulness as a treatment option for insomnia.

Sleep-wake patterns and disturbances in Portuguese primary school children: a comparison between 1995 and 2016

Purpose

It is often assumed sleep duration has decreased and sleep schedules have delayed over the last decades, as society modernized. We aimed to investigate changes in the sleep patterns of school-age children over time.

Methods

We compared the sleep timings, durations, and disturbances of primary school-age children in 1995 and roughly two decades later, in 2016. Data from 666 children attending the 3rd and 4th grades of basic education were combined from two different cross-sectional school-based studies conducted within the same educational region of mainland Portugal using the same parent-report questionnaire (Children's Sleep-wake Patterns Questionnaire).

Results

Mean sleep duration did not differ significantly between the two time points (schooldays: t = .118, p = .906; free days: t = 1.310, p = .191), albeit the percentage of children sleeping the recommended number of hours decreased significantly in 2016 when compared to 1995 (schooldays: χ2 = 4.406, p = .036; free days: χ2 = 16.859, p < .001). Wake-times advanced on free days in 2016. Difficulties on settling to sleep alone and returning to sleep were more prevalent in 2016, as well as fearing the dark and needing lights on or parent's presence to fall asleep.

Conclusions

Sleep onset-related disturbances appear to have increased from 1995 to 2016. One possible explanation for this increase might be the change in parental practices preventing children from learning to fall asleep autonomously.
