The effect of exercise on sleep habits of children with type 1 diabetic: a randomized clinical trial

BackgroundAdequate sleep and exercise are important components of the human lifestyle. Paying attention to these two factors is very important to improve the condition of children with type 1 diabetes. Therefore, this study aimed to investigate the effect of exercise on sleep habits in children with type 1 diabetes.Material & methods62 children with type 1 diabetes participated in this clinical trial. They will be divided into the intervention group (31) and the control group (31). Sleep habits were measured using the Children’s Sleep Habits Questionnaire (CSHQ). All children’s parents completed the CSHQ. The intervention for the experimental group consisted of 8 weeks of regular exercise program. The exercise program was prepared as an educational video and provided to parents. Paired sample t-test and ANCOVA test were used with SPSS 23.Results62 children with an average age of 9.32 ± 2.02 were studied. Fifty-four and eight% of the children were girls and the rest were boys. The analysis of the variance test showed a significant difference (F = 144.72, P ≤ 0.01) between the average score of the sleep habits of the control group (62.45 ± 5.12) and the experimental group (47.06 ± 4.39).ConclusionSleep habits in the experimental group improved after 8 weeks of exercise training using educational videos. Exercise as a non-pharmacological treatment is an effective way to manage diabetes and improve sleep quality in diabetic children.

Association between sleep pattern, salivary cariogenic bacteria and fungi populations, pH and buffering capacity in children: A comparative study.

Sleep quality has a significant impact on a child's health and is linked to oral and systemic diseases. It affects the circadian rhythm, which plays a crucial role in regulating the balance of the endocrine and hormonal systems. Current research has focused on exploring its role in the development of caries, which is influenced by inherent oral factors such as the composition of the oral microbiome and pH levels. This study aimed to investigate the relationship between bacterial population, pH, and buffering properties of saliva and sleep patterns in 8- to 12-year-old children. This cross-sectional study was conducted on 85 elementary school children aged 8-12 years. After obtaining written consent, non-stimulating saliva samples were collected using the spitting method. The participants' sleep pattern information was obtained with the use of the Persian version of the Children's Sleep Habits Questionnaire (CSHQ). Based on the results of the CSHQ, the participants were divided into 2 groups: those with appropriate sleep patterns; and those with inappropriate sleep patterns. The study compared the bacterial population of Streptococcus mutans, Lactobacillus spp. and Candida albicans, as well as the buffering capacity and pH of the saliva between the 2 groups. The statistical analysis employed the χ2 test, the independent samples t-test and Spearman's correlation. The group with inappropriate sleep patterns had significantly lower pH and buffering capacity (p < 0.001) and significantly higher colony counts of Lactobacillus and S. mutans (p < 0.001 and p = 0.012, respectively). There was no association between C. albicans and sleep patterns (p = 0.121). Inappropriate sleep patterns increase the population of caries-causing bacteria and reduce salivary pH and buffering capacity. This can be a significant factor in the development of dental caries in children aged 8-12 years.

Changed sleep according to weighted blanket adherence in a 16-week sleep intervention among children with attention-deficit/hyperactivity disorder.

To examine differences in sample characteristics and longitudinal sleep outcomes according to weighted blanket (WB) adherence. Children with attention-deficit/hyperactivity disorder (n = 94), mean age 9.0 (standard deviation 2.2, range 6-14) participated in a 16-week sleep intervention with WBs. Children were classified as WB adherent (use of WB ≥ 4 nights/wk) or nonadherent (use of WB ≤ 3 nights/wk). Changes in objectively measured sleep by actigraphy, parent-reported sleep problems (Children's Sleep Habits Questionnaire) and child-reported Insomnia Severity Index were evaluated according to adherence with mixed effect models. Sex, age, and attention-deficit/hyperactivity disorder subtype were examined as potential moderators. Children adherent to WBs (48/94) showed an early response in sleep outcomes and an acceptance of the WB after 4 weeks of use as well as a decrease in parent-reported (Children's Sleep Habits Questionnaire) (-5.73, P = .000) and child-reported (Insomnia Severity Index) (-4.29, P = .005) sleep problems after 16 weeks. The improvement in sleep was larger among WB adherent vs nonadherent (between-group difference: Children's Sleep Habits Questionnaire: -2.09, P = .038; Insomnia Severity Index: -2.58, P = .007). Total sleep time was stable for children adherent to WB but decreased for nonadherent (between-group difference: +16.90, P = .019). An early response in sleep and acceptance of the WB predicted later adherence to WBs. Improvements in sleep were more likely among WB adherents vs nonadherents. Children with attention-deficit/hyperactivity disorder may thus benefit from using WBs to handle their sleep problems. Lönn M, Svedberg P, Nygren J, Jarbin H, Aili K, Larsson I.

Analyzing the Quality of Life in Individuals with Fragile X Syndrome in Relation to Sleep and Mental Health.

The purpose of this paper was to examine the physical, emotional, social and school functioning domains of quality of life of individuals with Fragile X Syndrome, in relation to mental health and sleep patterns to gain a better understanding of how these aspects are affected by the disorder. This study included 119 individuals with Fragile X Syndrome who were given different cognitive examinations by a neuropsychologist or by parent-proxy questionnaires. This study focused on the Pediatric Quality of Life Inventory (PedsQoL), the Anxiety, Depression and Mood Scale (ADAMS), the Children's Sleep Habits Questionnaire (CSHQ), but did include other cognitive tests (Vineland Adaptive Behaviour Scales, Nonverbal IQ, Autism Diagnostic Observation Schedule). We identified significant associations between decreases in emotional, social and school domains of PedsQoL and the ADAMS subtests of Generalized Anxiety, Manic/Hyperactivity and Obsessive/Compulsivity, with the subtest of Depressed Mood having associations with lower physical and emotional domains. We also identified a significant impact between CSHQ subtests of Sleep Anxiety, Night Wakings, Daytime Sleepiness, and Parasomnia with the emotional and school domains of PedsQoL. There were associations connecting school functioning with Bedtime Resistance, and additional associations connecting emotional functioning with Sleep Duration and Sleep Onset Delay. Physical functioning was also associated with Sleep Anxiety. Our study shows how mental health and sleep defects impact improper sleep patterns and mental health which leads to decreases in the quality of life for individuals with FXS, and how it is important to screen for these symptoms in order to alleviate issues.

Sleep and internalizing problems in primary school children with attention-deficit hyperactivity disorder.

Internalizing and externalizing problems have received great attention, and children with ADHD exhibit high rates of comorbid internalizing and externalizing disorders. This study aimed to explore the relationship between sleep and internalizing problems in children with attention-deficit hyperactivity disorder (ADHD) and the probable mediating role of externalizing problems. A total of 203 primary school children diagnosed with ADHD for the first time were recruited for this study. Children with ADHD were evaluated by Children's Sleep Habits Questionnaire (CSHQ), Strengths and Difficulties Questionnaire (SDQ). Internalizing problems were represented by emotional symptoms and peer problems of SDQ, and externalizing problems were represented by conduct problems and hyperactivity-inattention problems of SDQ. Multi-step linear regression analysis was used to investigate the mediating effect of externalizing problems on the relationship between sleep and internalizing problems. Sleep in children with ADHD was associated with emotional problems in internalizing problems, and conduct problems in externalizing problems mediated the association between sleep and emotional problems. For children with ADHD, when it is difficult to identify internalizing problems, especially emotional problems, we can take sleep and externalizing problems as clues to improve our clinical ability to recognize and deal with emotional problems. 1. We first explored the possible mediating role of conduct problems between sleep and emotional problems in primary school children with ADHD. 2. When it is difficult to identify internalizing problems, especially emotional problems, we can take sleep and externalizing problems as clues to improve our clinical ability to recognize emotional problems for children with ADHD. 3. For children with ADHD with potential internalizing problems, especially emotional problems, interventions for their sleep and externalizing problems may be the possible methods to deal with.

The Impact of Cognitive Behavioral Therapy on Sleep Problems in Autistic Children with Co-occurring Anxiety.

This study seeks to examine the relationship between anxiety-symptom severity and sleep behaviors in autistic children receiving cognitive behavioral therapy (CBT). We conducted a secondary-data analysis from a sample of 93 autistic youth, 4 to 14 years, participating in 24 weeks of CBT. Clinicians completed the Pediatric Anxiety Rating Scale (PARS) and parents completed the Children's Sleep Habits Questionnaire, Abbreviated/Short Form (CSHQ-SF) at baseline, mid-treatment, post-treatment and 3months post-treatment. Mediation analysis evaluated the role of anxiety symptoms in mediating the effect of time in treatment on sleep. There was a negative association between time in treatment and scores on the CSHQ-SF (b = -3.23, SE = 0.493, t = -6.553, p < 0.001). Increased time in treatment was associated with decreased anxiety (b = -4.66, SE = 0.405, t = -11.507, p < 0.001), and anxiety symptoms decreased with CSHQ-SF scores (b = 0.322, SE = 0.112, t = 2.869, p = 0.005). The indirect effect of time in treatment on CSHQ-SF scores through PARS reduction was negative, but not statistically significant. Increased time in CBT was associated with decreased anxiety severity and improved sleep behaviors. Reductions in anxiety symptoms may mediate improvements in sleep problems, but larger sample sizes are necessary to explore this further.

Characteristics of sleep in children with heavy prenatal alcohol exposure.

Sleep plays an important role in neurodevelopment. However, the effects of prenatal alcohol exposure on sleep quality have been understudied, despite reports of sleep disturbance in infants prenatally exposed to alcohol and elevated levels of sleep problems reported by caregivers of children with fetal alcohol spectrum disorders. The current study characterizes sleep in children with prenatal alcohol exposure using both objective (actigraphy) and subjective (questionnaires, sleep diaries) methods. Participants aged 6-10 years, with and without prenatal alcohol exposure, were included in the study (alcohol-exposed [AE]: n = 35; control [CON]: n = 39). Objective sleep was measured via 24-h actigraphy for 2 weeks. Parents completed sleep diaries and sleep questionnaires (Children's Sleep Habits Questionnaire, Pediatric Sleep Questionnaire). Multivariate analysis of variance was used to characterize the sleep profile (objective, subjective) and examine group differences. There were no group differences on actigraphy metrics averaged across 2 weeks. However, the AE group showed significantly greater intraindividual variability on most actigraphy measures, particularly total sleep time, percent sleep, wake after sleep onset, and number of wake bouts. Parents reported significantly more sleep problems in the AE group than in the CON group, primarily driven by night wakings, parasomnias (e.g., sleepwalking), snoring, and daytime sleepiness. These effects were more severe in children >8.5 years of age. Despite similar 2-week average sleep outcomes, children with prenatal alcohol exposure showed greater intraindividual sleep variability and parents reported more sleep problems related to sleep behavior and snoring. These difficulties with sleep may be related to other cognitive and behavioral outcomes. Importantly, sleep is a modifiable behavior, and interventions that focus on variability in sleep, particularly in sleep duration, can impact the quality of life in children with prenatal alcohol exposure and their families.

Exploring the Effects of Repetitive Transcranial Magnetic Stimulation on Comorbid Sleep Disorders in Preschool Children with Attention-Deficit Hyperactivity Disorder.

Attention-deficit hyperactivity disorder (ADHD) is one of the most common neurological developmental disorders in children, and sleep disorders (SDs) are a common comorbidity in children with ADHD. There are currently no pharmacological treatment options for SD in children with ADHD of preschool age (4-6 years). Repetitive transcranial magnetic stimulation (rTMS) is a novel, non-invasive neuromodulation technique. This study explores the effectiveness of rTMS for comorbid SDs in preschool-aged children with ADHD. Thirty-five children of preschool age with ADHD and comorbid SDs were recruited for this study. The children were divided into a parent behavior management training (PBMT) group (n = 19) and a repetitive transcranial magnetic stimulation combined with parent behavior management training group (n = 16). Both groups underwent 8 weeks of treatment. The children's SD scores were assessed using the Chinese Children's Sleep Habits Questionnaire, were measured before the start, at the end, and 4 weeks after the end of the intervention, and were used to measure the effects. Within-group differences were compared using a repeated-measures analysis of variance, and between-group differences were compared using an independent samples t-test and Mann-Whitney U-test. Both the PBMT group and the rTMS combined with the PBMT group significantly improved the SDs of preschool-aged children with ADHD (P < .001), but the effect of the intervention was more pronounced in the rTMS combined with the PBMT group (P < .001) and lasted longer than the PBMT group (P = .004). Repetitive transcranial magnetic stimulation is a promising non-pharmacological therapy to improve SD in preschool-aged children with ADHD.

Mediating effects of sleep quality between clinical characteristics and quality of life in children with epilepsy: A cross-sectional study from Southwest China

BackgroundAlthough sleep quality (SQ) reportedly affects the health-related quality of life (QOL) of patients with epilepsy, little is known about the potential association between SQ and QOL, particularly in children with epilepsy (CWE). Our study aimed to investigate the mediating effect of SQ on the QOL of CWE to obtain more information for the prevention and treatment of epilepsy in children. MethodsWe collected general demographic and clinical data of 212 CWE and 79 controls (children who visited the Health Examination Department), and their guardians were instructed to answer the Children’s Sleep Habits Questionnaire (CSHQ) and the optimized Quality of Life in Childhood Epilepsy Questionnaire-16 (QOLCE-16). The t-test, analysis of variance, chi-square test, and Fisher’s exact test were used for between group comparisons. The Pearson correlation was used to analyze the correlation between variables. The direct, indirect, and total effects of predictors on the QOL of CWE were estimated based on an adjusted mediation model. ResultsCWE had significantly smaller long-term urban residence rates, less educated guardians, higher total CSHQ score, higher incidence of poor SQ, higher bedtime resistance, more sleep anxiety, worse sleep-disordered breathing, increased parasomnia, more daytime sleepiness, more frequent night waking, and greater sleep onset delay than controls (P < 0.05 for all). The univariable analysis showed significant differences in total CSHQ scores between CWE with different seizure frequency in the last month, whether or not drug-resistant epilepsy (DRE), and with different video electroencephalogram (VEEG) findings (P < 0.05 for all). Differences in QOLCE-16 scores between CWE with different guardian’s employment status, age at diagnosis, number of anti-seizure medication (ASM) types, seizure frequency in the last month, DRE status, seizure type, VEEG findings, neuropsychological evaluation findings, magnetic resonance imaging (MRI) findings, and etiology were statistically significant (P < 0.05 for all). The correlation study indicated that the total CSHQ score was negatively correlated with the QOLCE-16 score (P < 0.05). The mediation analysis showed that DRE and VEEG abnormalities had a standardized direct effect on the QOL. Seizure frequency in the last month, DRE, and VEEG abnormalities had an indirect effect on the QOL through SQ, and their mediating effect values of SQ were 31.61 %, 13.45 %, and 14.35 %, respectively. ConclusionOur findings uncovered the relationship of some clinical characteristics with SQ and QOL and characterized the nature of factors affecting the QOL of CWE. SQ could be a key factor in the prognosis of CWE experiencing epileptic seizures, and more attention should be paid on the management of SQ in interventions for epilepsy.

Evaluation of Sleep Habits and Their Relationship With Quality of Life in Children With Epilepsy

BackgroundThe aim of this study was to investigate sleep habits, quality of life (QoL), and the relationship between them in children with epilepsy. MethodsIn this cross-sectional study, children aged two to 18 years being followed up for epilepsy were assessed using the Children's Sleep Habits Questionnaire (CSHQ) and the Pediatric Quality of Life Inventory (PedsQL). Pearson or Spearman correlation analysis was performed to examine the relationship between normally distributed and non-normally distributed variables, respectively. Linear regression analysis was used to examine independent variables associated with PedsQL total scale score. Level of significance was accepted as P < 0.05. ResultsThe study included 112 children with a mean age of 10.5 ± 4.4 years (51.8% female). The frequency of poor sleep habits was 96.4%. There was a good level of agreement between children's and parents' PedsQL total, physical health, and psychosocial health scores (P < 0.001). Correlation analysis between QoL and sleep parameters revealed negative correlations between total sleep score and self-assessed PedsQL total scale, physical health, and psychosocial health scores (P < 0.05) and parent-assessed PedsQL total scale and psychosocial health scores (P < 0.05). The results of linear regression analysis indicated that the factors most significantly associated with lower QoL were high CSHQ total sleep score and exclusively daytime seizures (P < 0.001). ConclusionsIt was found that children with epilepsy had poor sleep habits and low QoL and that poor sleep habits have a negative impact on QoL.

Sleep Habits and Behavioral Problems in Preschool-aged Children with ADHD

Objective: This study aimed to investigate the relationship between sleep habits and behavioral problems in preschool-aged children with ADHD. Materials and Methods: A cross-sectional study was conducted in a child developmental clinic at Siriraj Hospital between October and December 2023. Parents of children aged 4-6 years with ADHD completed the Children’s Sleep Habits Questionnaire (CSHQ) and the Strengths and Difficulties Questionnaire (SDQ). Descriptive analysis, Pearson correlation, and multivariate linear regression analysis were used to examine the association between sleep habits and behavioral problems. Results: This study recruited 80 preschoolers with ADHD and 75% were boys. The mean total CSHQ score was 43.76 ± 7.38 and 40% of the participants had sleep problems. 31.3 % had clinically significant behavioral problems. The most common behavioral problems were hyperactivity (33.8%), emotional problems (16.3%), and conduct behavior (10%). More sleep disturbances were highly correlated with all behavioral problems in SDQ, with a Pearson correlation between 0.78 and 0.90. After multivariate regression analysis, the total CSHQ score remained the strongest predictor of all domains of behavioral problems in preschool-aged children with ADHD (p &lt; 0.05). Conclusion: More than 1/3 of preschool children with ADHD were affected by sleep disturbances. Furthermore, sleep problems in these children can contribute to significant behavioral problems. Therefore, the treatment of ADHD in preschoolers should always include the management of sleep disturbances.

Substituting Book Reading for Screen Time Benefits Preschoolers' Sleep Health: Results from the Ulm SPATZ Health Study.

Healthy sleep is essential for the physical, cognitive, and social development of children. Several studies have reported the increase in digital media use in preschool children and its association with impaired sleep. However, there is relatively little evidence on the effects of book reading as a potentially safe alternative. The objective of this study, therefore, was to investigate whether sleep in children could benefit from book reading, and whether the negative effects of media use on sleep can be mitigated by substituting book reading for screen time. We used longitudinal data from three consecutive waves of the SPATZ Health study, including children at the ages of 4 (n=581), 5 (n=508), and 6 (n=426) years. All data were collected by self-administered questionnaires. Parent-reported child sleep was assessed by the Children's Sleep Habits Questionnaire. Across the three waves, screen-based media use increased and was associated with lower sleep quality. In contrast, the time spent with book reading decreased; however, book reading appeared to be beneficial for children's sleep. Substitution models revealed that the theoretical substitution of an equal amount of book reading for 50% of the time spent with screen-based media benefits several domains of preschoolers' sleep health, including parasomnias, sleep anxiety, daytime sleepiness, and sleep onset delay. Besides implications for population-wide and individual prevention, book reading may also be incorporated as a useful intervention to improve sleep quality in children who are already affected by sleep problems. Given that book reading is perceived as a safe alternative, the presented evidence may suffice to support recommendations in this direction.

An evaluation of a stepped-care telehealth program for improving the sleep of autistic children

BackgroundSleep problems are prevalent in Autistic children, adversely affecting their development, well-being and quality of life. Traditional face-to-face behavioral interventions are hindered by accessibility. Using a single-case design, this study evaluated the efficacy of a stepped-care telehealth-delivered behavioral sleep intervention (TDBSI). MethodSeven Autistic children (aged 4–8) and their parents participated in a 12-week program consisting of baseline plus three sequential intervention phases: (1) self-directed online parent psychoeducation, (2) small group parent coaching via video conferencing, and (3) individualized parent coaching via video conferencing. Parent strategy selection and implementation fidelity were closely monitored and rated across intervention phases. Child sleep outcomes were assessed through daily parent-reported sleep diaries and the Children's Sleep Habits Questionnaire. ResultsFive of seven parents used online parent education to independently select antecedent strategies (e.g., sleep hygiene, stimulus control) and/or rewards that were appropriate for their child’s sleep and implemented them with high fidelity. This resulted in reductions in sleep onset latency, night wakings, early wakings, and bedsharing for their children. Parent implementation fidelity and child sleep outcomes were further improved for all participants with group or individualized coaching, and results were maintained at 12 weeks and six months post-intervention. ConclusionsTDBSIs show promise in addressing sleep difficulties in Autistic children, warranting further investigation and replication.

Changes in health-related quality of life and sleep habits after a 6-month non-randomised cluster-controlled trial among children with overweight or obesity

Being overweight or obese can have severe negative psychological impacts and reduce health-related functioning. To improve health-related quality of life (HRQoL) and sleep habits for children with overweight or obesity, it is important to design and implement effective interventions. The aim of this study was to evaluate the effects of a 6-month family-based lifestyle intervention on HRQoL and sleep habits in Norwegian children with overweight or obesity in a primary-care setting. This 6-month, non-randomised, cluster-controlled trial included Norwegian children aged 5–13 years with overweight or obesity and their parents. A questionnaire was filled out by the parents. A total of 33 and 52 children in the control group and 41 and 78 children in the intervention group answered the HRQoL and sleep habits questions, respectively, and were included. The intervention group received individual family counselling and participated in physical activity groups and nutrition courses. The Children’s Sleep Habits Questionnaire (CSHQ) and Kidscreen-10 index were used to assess sleep habits and HRQoL. At baseline, the mean average scores for HRQoL were 50.0 [standard deviation (SD) 8.1] for the intervention group and 49.0 (SD 10.1) for the control group. For sleep habits at baseline, the mean average scores were 45.2 (SD 11.8) for the intervention group and 46.0 (SD 11.9) for the control group. No significant changes in HRQoL and sleep habits after the intervention were revealed. Overall, the family-based lifestyle intervention targeting overweight and obese children in a primary-care setting showed no significant effect on HRQoL or sleep quality.

Methylphenidate and Sleep Difficulties in Children and Adolescents With ADHD: Results From the 2-Year Naturalistic Pharmacovigilance ADDUCE Study

Objective: Short-term RCTs have demonstrated that MPH-treatment significantly reduces ADHD-symptoms, but is also associated with adverse events, including sleep problems. However, data on long-term effects of MPH on sleep remain limited. Methods: We performed a 2-year naturalistic prospective pharmacovigilance multicentre study. Participants were recruited into three groups: ADHD patients intending to start MPH-treatment (MPH-group), those not intending to use ADHD-medication (no-MPH-group), and a non-ADHD control-group. Sleep problems were assessed with the Children’s-Sleep-Habits-Questionnaire (CSHQ). Results: 1,410 participants were enrolled. Baseline mean CSHQ-total-sleep-scores could be considered clinically significant for the MPH-group and the no-MPH-group, but not for controls. The only group to show a significant increase in any aspect of sleep from baseline to 24-months was the control-group. Comparing the MPH- to the no-MPH-group no differences in total-sleep-score changes were found. Conclusion: Our findings support that sleep-problems are common in ADHD, but don’t suggest significant negative long-term effects of MPH on sleep.

Quiet Time Means No Screen Time: A Project Aiming to Increase Restful Sleep within the Pediatric Acute Care Unit

AbstractThe use of blue-light-emitting smart devices prior to bedtime has been identified as one of the reasons of increased pediatric sleep disturbances and poor sleep quantity. Interrupted sleep is a risk factor for healing and well-being in the pediatric acute ward. The aim of this project was to promote high-quality sleep within our pediatric ward by implementing a standardized protocol that eliminated exposure to electronic blue light prior to bedtime, per recommendations from the American Academy of Pediatrics. Our objective was to promote enhanced quantity of sleep and healing by restricting and removing all smart devices during nighttime hours in the pediatric acute ward. We utilized the Bedtime issues, Excessive daytime sleepiness, night Awakenings, Regularity and duration of Sleep, and Snoring validated screening tool, Children Sleep Habit Questionnaire, and included a survey question regarding smart device use to evaluate patients' sleep routine. After the implementation of “no screen time” innovation, patients' and parents' quantity of sleep and total restful hours was reassessed and pre/post results analyzed. The pilot project evaluated 57 patients aged 18 months to 19 years with varying admitting diagnoses. The quiet time innovation results demonstrated improved length and reported uninterrupted sleep among patients. Eliminating electronic screens during evening (sleeping) hours in the acute care setting was associated with improved sleep among pediatric patients, enhancing potential for recovery, promoting well-being, and modeling effects of limiting screen time for participants.

Association of sleep timings, duration, consistency, and chronotype with premyopia and myopia among Indian children.

To explore the association of sleep timings, duration, consistency, and chronotype with premyopia and myopia among Indian children. This hospital-based cross-sectional study included 453 children, aged 6-12 years. Two myopia participants were selected for each individual with the corresponding premyopia or emmetropia. All children underwent cycloplegic autorefraction and ocular biometric tests. The Children's Sleep Habits Questionnaire (CSHQ) and parental information on behavioral habits were used to assess the association of sleep parameters with myopia and premyopia using logistic regression models. Both myopia and premyopia exhibited significant late bedtime, short sleep duration, early wakeup time on only weekdays, and longer weekend catch-up sleep than emmetropia children (p < 0.05). In multivariate analysis, late bedtime (more than 24:00 a.m.) on weekdays (Odds ratio, OR = 3.63, 95% CI [0.74, 8.68]) as well as on free days (OR = 1.04, 95% CI [0.02, 8.08]); and early wake-up time only on weekdays (5:00-6:00 a.m., OR = 2.16, 95% CI [0.24, 6.76] and 06:00-07:00 a.m., OR = 2.42, 95% CI [0.51, 8.44]) were associated with increased risk of myopia (all p < 0.05) but not premyopia. After adjusting the confounding factors, when each of the eight CSHQ subscale components was analyzed, only bedtime resistance, night waking, and daytime sleepiness scores were significantly associated with a higher risk for premyopia and myopia (p < 0.05). The sleep quality components, including bedtime resistance, night waking, and daytime sleepiness, equally involve a higher risk for myopia as well as premyopia.

Relationship between sleep status and occasional hypertension in preschool children in three provinces in the middle and lower reaches of the Yangtze River in China

Objective: To understand the prevalence of occasional hypertension in preschool children in three provinces in the middle and lower reaches of the Yangtze River in China, and analyze the relationship between their sleep status and occasional hypertension. Methods: From October to November 2017, a total of 24 842 preschool children from 109 kindergartens in 11 cities in Hubei, Anhui and Jiangsu provinces were selected by intentional sampling method. A self-made questionnaire was used to collect basic information about the subjects, and the sleep status data was collected by the Children's Sleep Habits Questionnaire. Physical examinations were performed on the subjects, and height, weight and blood pressure were measured on-site. The difference in occasional hypertension detection rate among preschool children with different characteristics was compared, and the correlation between sleep status and occasional hypertension detection rate was analyzed by the multivariate logistic regression model. Results: The age of the subjects was (4.4±1.0) years, including 12 729 boys (51.2%). The prevalence of occasional hypertension was 31.8% (7 907/24 842). The prevalence of occasional hypertension among preschool children in three provinces of the middle and lower reaches of the Yangtze River was 31.8%. There were statistically significant differences in the detection rate of occasional hypertension among preschool children of different genders, age groups, family residence, family economic status and parents' education level (all P values<0.05). The detection rate of occasional hypertension in children with less than 10 hours of sleep was higher than those with sufficient sleep, and the difference was statistically significant (P<0.05). The results of multivariate logistic regression analysis showed that after adjusting for factors such as gender, age, family residence, family economic status, parental education level, parental smoking history, and physical constitution, the ORs (95%CI) for less than 10 hours of sleep, turning on the lights while sleeping, and poor sleep quality were 1.09 (1.03-1.15), 1.17 (1.07-1.28) and 1.04 (0.91-1.18), respectively, compared with the corresponding reference group. Conclusion: The detection rate of occasional hypertension is high in preschool children in the middle and lower reaches of the Yangtze River and there is a positive correlation between insufficient sleep and turning on the light when sleeping and occasional hypertension in preschool children.

Primary School-Aged Children's Physical Activity Level, Eating Habit, and Sleeping Pattern Changes During the COVID-19 Pandemic in Indonesia.

Background and objective This study aims to explore the effect of physical distancing on physical activity, eating habits, and sleeping patterns among Indonesian primary schoolchildren during theCOVID-19pandemic. Methodology This cross-sectional study was conducted from October to December 2020, involving 489 primary schoolchildren. Parents/caregivers were queried about changes in their children's physical activity (utilizing the Physical Activity Questionnaire for Older Children - PAQ-C), eating habits (via a questionnaire modified from Southeast Asian Nutrition Surveys - SEANUTS), and sleeping patterns (assessed using the Children's Sleep Habits Questionnaire - CSHQ) both before and during the pandemic. Various sociodemographic characteristics and income status were also obtained. Paired univariate and multivariate analyses were conducted where applicable. Results In comparison to the period before the pandemic, both the PAQ-C score and active proportion significantly decreased during the pandemic (P= 0.000). Children consumed more snacks (322, 65.8%)but less canned and processed foods (180, 36.8%, and 128, 26.2%, respectively). Sleep duration and sufficiency increased significantly, with a CSHQ score mean of 48.62 ± 9.88 (P= 0.000, P= 0.004), and sleep disturbance was observed in 391 (79.96%)subjects. Conclusions Children were physically less active during the COVID-19 pandemic. They also experienced variable changes in eating habits based on parental employment, family income and expenses, and the presence of governmental support. While more children had longer sleep duration and more achieved the recommended sleep time, sleep disturbance happened in most subjects.

Effect of Foot Reflexology Massage on Sleep Habits in Children with Autistic Spectrum Disorder: A Randomized Clinical Trial

Background: Sleep plays a crucial role in children's motor, mental, and cognitive development. Due to the significant prevalence of sleep problems in children with autism and the side effects of pharmacological therapy, complementary interventions should be considered. Objectives: This study aimed to investigate the effect of foot reflexology massage on sleep habits in children with autistic spectrum disorder. Methods: This randomized clinical trial was conducted on 60 children with autistic spectrum disorder in Mashhad, Iran. The control group received routine care from the family. In the intervention group, in addition to the routine family care, a foot reflexology massage was performed for 15 min by parents for 30 nights before bedtime for children. The standard Children's Sleep Habits Questionnaire (CSHQ) was completed 3 times in both groups. In the control group, the questionnaire was completed at the beginning of the study, on the 15th day, and on the 30th day after entering the study. In the intervention group, the questionnaire was completed before the intervention, on the 15th day after the intervention, and on the 30th day after the intervention. Data were analyzed using SPSS version 16 by the independent t-test, Mann-Whitney test, and repeated measures analysis of variance (ANOVA). Results: Among the children included in the study, 78.3% were male, and their mean age was 8.56 ± 2.4 years. The mean total score of children's sleep habits before the intervention was not significantly different between the control and intervention groups (P = 0.71). After the intervention, the mean total score of children's sleep habits was significantly different between the control and intervention groups (P = 0.001). The foot reflexology massage, with a score reduction of 8.13 ± 3.95 points, had a significant impact on the score of sleep habits in the intervention group (P = 0.002). Conclusions: Foot reflexology massage improves the quality of sleep in children with autism and can be recommended as a safe intervention for parents of children with autism.
