Sleep Hygiene Practices and Its Impact on Mental Health and Functional Performance Among Adults in Tabuk City: A Cross-Sectional Study.

Background Poor or imperfect sleep hygiene practices include all factors that promote arousal or disrupt the normal balance of the sleep-wake cycle. It is necessary to clarify the relationship between sleep hygiene behaviors and a person's mental health. This may allow a better understanding of this problem and might help design effective awareness programs about good sleep hygiene practices for reducing the serious outcomes of this problem. Therefore, the current study was conducted to evaluate sleep hygiene practices and assess the impact of sleep hygiene on sleep quality and the mental health of the adult population of Tabuk city, Saudi Arabia. Methodology This cross-sectional, survey-based study was conducted in Tabuk city, Saudi Arabia in 2022. All adult residents of Tabuk city, Saudi Arabia were invited to participate. Participants with incomplete data were excluded from the study. A self-administered questionnaire was developed by the researchers to assess sleep hygiene practices and their impact on the sleep quality and mental health of the study participants. Results The study included 384 adults. There was a significant association between the frequency of sleep problems and poor sleep hygiene practices (p < 0.001). The percentage of subjects who had problems sleeping during the past three months was significantly higher among those having poor sleep hygiene practices (76.5%) than their counterparts (56.1%). The rates of excessive or severe daytime sleepiness were significantly higher among individuals with poor hygiene practices (22.5% versus 11.7% and 5.2% versus 1.2%, p = 0.001). Participants with depression were found to be significantly higher among the poor hygiene group (75.8%) in comparison to those having good hygiene practices (59.6%) (p = 0.001). Conclusions The findings of the present study indicate significant associations between poor sleep hygiene practices and sleep problems, daytime sleepiness, and depression among adult residents of Tabuk city, Saudi Arabia.

Use of hypnotic drugs among Scandinavian children, adolescents, and young adults

IntroductionHypnotic drug use in children and adolescents is widely debated.ObjectivesTo describe use of hypnotic drugs (melatonin, z-drugs and sedating antihistamines) among 5-24-year-old Scandinavians during 2012 to 2018.MethodsAggregate-level data from public data sources in Sweden, Norway and Denmark. We calculated annual prevalence (users/1000 inhabitants) stratified by sex, age group and country. Quantity of use (Defined Daily Dose (DDD)/user/day) was estimated for Norway and Denmark.ResultsMelatonin was most frequently used, with an increase from 2012 to 2018 in all countries. Sweden presented the highest rise (7 to 25/1,000) compared to Denmark (6 to 12/1,000) and Norway (10 to 20/1,000). The increase was strongest for females and 15-24-year-olds. Melatonin use was twice as common for males under age 15 years, and slightly more common for females thereafter. The annual prevalence of sedating antihistamine use doubled from 7 to 13/1,000 in Sweden, whereas it was more stable in Norway and Denmark, reaching 8/1,000 and 3/1,000, respectively. Z-drug use decreased in all countries, lowering to 4/1,000 in Sweden and Norway in 2018 and 2/1,000 in Denmark. The quantity of hypnotic use in Norway and Denmark was 1 DDD/user/day for melatonin, as compared to 0.1-0.3 for z-drugs and antihistamines.ConclusionsThere is an increasing use of melatonin and sedating antihistamines among Scandinavian children, adolescents and young adults. The increase is more pronounced in Sweden compared to Norway and Denmark. This Scandinavian discrepancy could reflect variation in frequency of sleep problems or national variation in clinical practice or health care access.DisclosureNo significant relationships.

Allergic disease, sleep problems, and psychological distress in children recruited from the general community

BackgroundIt is not clear which allergic disease is most strongly related to which sleep problem and whether sleep problems may mediate the association between allergic disease and psychological distress. There is also a need for more community-based studies using nonreferred samples. ObjectiveTo evaluate the association between individual allergic diseases and sleep problems and test whether the association between allergic disease and psychological distress is mediated through sleep problems. MethodsParents of 1449 Australian children aged 6 to 10 years recruited from the general community, completed measures of sleep problems (Pediatric Sleep Survey Instrument), psychological distress (Strengths and Difficulties Questionnaire), and frequency of allergic diseases. ResultsSleep and psychological distress scores were in the reference range. After controlling for coexisting allergic diseases, allergic rhinitis was associated with sleep routine problems, morning tiredness, night arousals, sleep disordered breathing and restless sleep; asthma with sleep routine problems, sleep disordered breathing and restless sleep; and eczema with restless sleep. Path analyses revealed that sleep problems mediated the association between asthma and allergic rhinitis but not eczema with psychological distress. ConclusionIn this nonreferred community sample, the frequency of sleep problems and psychological distress was lower than that typically reported in children referred to specialized centers. However, allergic rhinitis was associated with a broad range of sleep problems and to a lesser extent in children with asthma and least in children with eczema. Path analysis revealed that the association between allergic disease and psychological distress was mediated through sleep problems, highlighting the importance of assessing sleep health in children with allergic disease.

Use of hypnotic drugs among children, adolescents, and young adults in Scandinavia.

Hypnotic use in children and adolescents is controversial. To describe the use of hypnotic drugs (melatonin, z-drugs, and sedating antihistamines) among 5- to 24-year-old Scandinavians during 2012 to 2018. Aggregate-level data were obtained from public data sources in Sweden, Norway, and Denmark. We calculated annual prevalence (users/1000 inhabitants) stratified by age group, sex, and country. Quantity of use (Defined Daily Dose (DDD)/user/day) was estimated for Norway and Denmark. Melatonin was the most commonly used hypnotic, and its use increased markedly from 2012 to 2018, particularly among females and 15- to 24-year-old individuals. Sweden had the highest increase in use (6.5 to 25/1000) compared with Norway (10-20/1000) and Denmark (5.7-12/1000). The annual prevalence of sedating antihistamine use was also highest in Sweden, reaching 13/1000 in 2018 in comparison to 7.5/1000 in Norway and 2.5/1000 in Denmark. Z-drug use decreased in all countries toward 2018, dropping to 3.5/1000 in Sweden, 4.4/1000 in Norway, and 1.7/1000 in Denmark. The quantity of hypnotic use in Norway and Denmark was 0.8-1.0 DDD/user/day for melatonin in 2018, as compared to 0.1-0.3 for z-drugs and antihistamines. The use of melatonin and sedating antihistamines increased among young Scandinavians during 2012-2018, and the increase was twice as high in Sweden compared with Norway and Denmark. In addition, Sweden had the highest use of sedating antihistamines. The Scandinavian variation of hypnotic use could reflect differences in frequency of sleep problems between populations or variation of healthcare access or clinical practice between countries.

Fluoride exposure and duration and quality of sleep in a Canadian population-based sample

BackgroundFluoride from dietary and environmental sources may concentrate in calcium-containing regions of the body such as the pineal gland. The pineal gland synthesizes melatonin, a hormone that regulates the sleep-wake cycle. We examined associations between fluoride exposure and sleep outcomes among older adolescents and adults in Canada.MethodsWe used population-based data from Cycle 3 (2012–2013) of the Canadian Health Measures Survey. Participants were aged 16 to 79 years and 32% lived in communities supplied with fluoridated municipal water. Urinary fluoride concentrations were measured in spot samples and adjusted for specific gravity (UFSG; n = 1303) and water fluoride concentrations were measured in tap water samples among those who reported drinking tap water (n = 1016). We used multinomial and ordered logistic regression analyses (using both unweighted and survey-weighted data) to examine associations of fluoride exposure with self-reported sleep outcomes, including sleep duration, frequency of sleep problems, and daytime sleepiness. Covariates included age, sex, ethnicity, body mass index, chronic health conditions, and household income.ResultsMedian (IQR) UFSG concentration was 0.67 (0.63) mg/L. Median (IQR) water fluoride concentration was 0.58 (0.27) mg/L among participants living in communities supplied with fluoridated municipal water and 0.01 (0.06) mg/L among those living in non-fluoridated communities. A 0.5 mg/L higher water fluoride level was associated with 34% higher relative risk of reporting sleeping less than the recommended duration for age [unweighted: RRR = 1.34, 95% CI: 1.03, 1.73; p = .026]; the relative risk was higher, though less precise, using survey-weighted data [RRR = 1.96, 95% CI: 0.99, 3.87; p = .05]. UFSG was not significantly associated with sleep duration. Water fluoride and UFSG concentration were not significantly associated with frequency of sleep problems or daytime sleepiness.ConclusionsFluoride exposure may contribute to sleeping less than the recommended duration among older adolescents and adults in Canada.

Impact of methylphenıdate and atomoxetıne on sleep ın chıldren wıth ADHD

Aim: Our purpose in this study is to determine the effects of methylphenidate and atomoxetine on the sleep of children with attention-deficit/hyperactivity disorder (ADHD). Methods: Eighty-one children admitted to a child psychiatric inpatient service with ADHD participated in a double-blind, crossover study in which 42 subjects received extended release methylphenidate, and 39 subjects received atomoxetine only one dose in the morning daily at least for 6 months. Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (KSADS-PL) and Child Sleep Habits Survey (CSHS) were applied to all children. Results: There was a sleep problem in 81% (n = 34) of the patients using methylphenidate and 89.7% (n=35) of the group using atomoxetine. When we evaluated according to the CSHS cut-off score, whether having a sleep problem or sleep problems, and there was no statistically significant difference between the two groups (p&gt; 0.05). We are not able to find significant difference between two groups in terms of bedtime resistance, sleep duration, sleep anxiety, night awakenings, parasomnia, sleep-breathing problems, and daytime sleepiness subtest and total sleep scores (p&gt; 0.05). There was a significant difference in sub-test of the falling asleep duration. It was found that the methylphenidate group had a longer falling asleep time duration(p &lt;0.05). Discussion: Sleep-related complaints in children diagnosed with ADHD are not uncommon in clinical practice. It is known that 25-55% of children with ADHD often report various sleep problems and in addition, more sleep problems are reported by their parents. In our study, when the total scores of CSHS filled by the family were evaluated, this rate was found to be 85%. There was no difference in the frequency of sleep problems between the group using methylphenidate and the group using atomoxetine. In our study, there was significant difference between the group using methylphenidate and the group using atomoxetine in terms of delay in falling asleep. In many studies based on both objective and subjective measurements, psychostimulant drugs have been reported to be associated with difficulty falling asleep and prolonged sleep latency. Sleep disorders are common in ADHD. It is important that child and adolescents with ADHD must be evaluated the sleep habits before medical treatment to identify the etiology of sleep disorders.

Fluoride exposure and duration and quality of sleep in a Canadian cohort

Background: Research suggests that fluoride from dietary and environmental sources may concentrate in calcium-containing regions of the body such as the pineal gland. The pineal gland synthesizes melatonin, a hormone that regulates the sleep-wake cycle. We used population-based data from Cycle 3 (2012-2013) of the Canadian Health Measures Survey (CMHS) to examine associations between fluoride exposure and sleep outcomes.Methods: The sample included participants aged 16 to 79 years. Fluoride concentrations were measured in urinary spot samples (n=1303) and household tap water among those who reported drinking tap water (n=1016); urinary fluoride was adjusted for specific gravity (UFSG). We used multinomial and ordered logistic regression analyses to examine associations of fluoride exposure with self-reported sleep outcomes, including sleep duration and frequency of sleep problems. Sleep duration was classified as normal, low, or high according to age-based recommendations by the National Sleep Foundation, and frequency of sleep problems were measured on a 5-point scale, ranging from “never” to “all of the time”. Covariates were based on theoretical relevance and included age, sex, ethnicity, body mass index, and household income.Results: Median (IQR) UFSG and water fluoride concentrations were 0.67 (0.63) and 0.12 (0.38) mg/L, respectively; 32% of participants lived in communities supplied with fluoridated municipal water. A 0.5 mg/L increase in water fluoride level was associated with 34% higher relative risk of reporting sleeping less than the recommended duration [RRR = 1.34, 95% CI: 1.03, 1.73; p = .026]. UFSG was not significantly associated with sleep duration. Water fluoride and UFSG concentration were not significantly associated with frequency of sleep problems. Including chronic health conditions as a covariate did not substantially change the association between water fluoride and sleep duration.Conclusions: Fluoride exposure may contribute to sleeping less than the recommended duration among older adolescents and adults in Canada.

Sleep Problems Are Related to a Worse Quality of Life and a Greater Non-Motor Symptoms Burden in Parkinson's Disease.

The aim of the present study was to examine the frequency of self-reported sleep problems and their associated factors in a large cohort of PD patients. PD patients and controls, recruited from 35 centers of Spain from the COPPADIS cohort were included in this cross-sectional study. Sleep problems were assessed by the Spanish version of the Parkinson's disease Sleep Scale version 1 (PDSS-1). An overall score below 82 or a score below 5 on at least 1 item was defined as sleep problems. The frequency of sleep problems was nearly double in PD patients compared to controls: 65.8% (448/681) vs 33.5% (65/206) (p < 0.0001). Mean total PDSS score was lower in PD patients than controls: 114.9 ± 28.8 vs 132.8 ± 16.3 (p < 0.0001). Quality of life (QoL) was worse in PD patients with sleep problems compared to those without: PDQ-39SI, 19.3 ± 14 vs 13 ± 11.6 (p < 0.0001); EUROHIS-QoL8, 3.7 ± 0.5 vs 3.9 ± 0.5 (p < 0.0001). Non-motor symptoms burden (NMSS; OR = 1.029; 95%CI 1.015-1.043; p < 0.0001) and impulse control behaviors (QUIP-RS; OR = 1.054; 95%CI 1.009-1.101; p = 0.018) were associated with sleep problems after adjustment for age, gender, disease duration, daily equivalent levodopa dose, H&Y, UPDRS-III, UPDRS-IV, PD-CRS, BDI-II, NPI, VAS-Pain, VAFS, FOGQ, and total number of non-antiparkinsonian treatments. Sleep problems were frequent in PD patients and were related to both a worse QoL and a greater non-motor symptoms burden in PD. These findings call for increased awareness of sleep problems in PD patients.

Sleep Problems and Effective Factors in Preschool Children.

AimThis descriptive field study was carried out to determine the prevalence of sleep problems and affecting factors in preschool children.MethodThe universe of this descriptive study consisted of 5454 children studying in kindergartens affiliated to the Ministry of National Education in İzmir. The study sample consisted of 325 children aged 4–6 years attending preschool and their mothers/caregivers in three kindergartens in İzmir. Data were collected by interviewing the mothers by using the “Brief Infant Sleep Questionnaire Turkish Form.” SPSS 16.0 package program was used to evaluate the data. The data were presented as numbers, percentages, and median, and chi-square statistical tests were used to analyze the data.ResultsBy calculating the seven parameters (sleep level measurements) of the Baby/Child Sleep Problem Diagnosis Form, the prevalence of sleep problems in children was found to be 43.4%. There was no difference in the frequency of sleep problems according to age and sex of children (p>0.05). Sleep problems were most prevalent in children of mothers with high school degree and least prevalent in children of mothers with college and above educational status (p<0.05). No difference was found between the children who had their own room for sleeping and those who did not (p>0.05). Sleeping problems were most prevalent among children who slept in the room of their siblings, another person, or in their parents’ bed (p<0.05).ConclusionNurses should interview mothers in all health institutions and determine sleeping problems during the nursing assessment process and provide counseling and education to mothers.

Sleep quality and risk of cancer: findings from the English longitudinal study of aging.

To prospectively examine the association between sleep quality and incident cancer risk in the elderly. A total of 10,036 participants aged ≥50 years free of cancer at baseline from the English Longitudinal Study of Ageing at wave 4 (2008) were included, and followed up until 2016. The primary endpoint was new onset physician-diagnosed cancer. Sleep quality was assessed by four questions regarding the frequency of sleep problems and overall subjective feeling of sleep quality in the last month, with higher score denoting poorer sleep quality. The multivariable Cox regression model was used to calculate hazard ratio (HR) with 95% confidence interval (CI) for incident cancer risk according to sleep quality. At 8-year follow-up, a total of 745 (7.4%) participants developed cancer. Compared with good sleep quality at baseline, HR (95% CI) for incident cancer risk was 1.328 (1.061, 1.662) for intermediate quality, 1.586 (1.149, 2.189) for poor quality. Similarly, compared with maintaining good sleep quality in the first 4 years, HR (95% CI) for incident cancer risk was 1.615 (1.208, 2.160) for maintaining intermediate quality and 1.608 (1.043, 2.480) for maintaining poor quality. The exclusion of participants with family history of cancer or abnormal sleep duration yielded consistent results. Poor sleep quality is positively associated with the long-term risk of developing cancer in an elderly cohort. Both medical staffs and the general public should pay more attention to improving sleep hygiene.

Sleep among youths in foster care: Associations with potentially traumatic events, PTSD and mental health

AbstractAmong maltreated youth in foster care, little is known about frequency of sleep problems and its association to potential traumatic events (PTEs) and mental health. Among youths in foster care, we examined: (1) sleep patterns, difficulties initiating and maintaining sleep (DIMS) and related functional impairment; (2) whether exposure to PTEs, symptoms of post‐traumatic stress disorder (PTSD) and general mental health problems are associated with DIMS and related functional impairment, controlling for age, gender and time in foster care; and (3) whether PTSD and general mental health problems mediate the association between PTEs and DIMS. Foster youths in Norway (n = 299) completed a survey on sleep behaviour, the Child and Adolescent Trauma Screen, and the Strengths and Difficulties Questionnaire. Overall, 53.2% reported DIMS. For 82.1%, these sleep problems had lasted 3 months plus. Increased PTEs, PTSD and general mental health problems were all associated with increased DIMS score. Increased rate of PTEs was associated with decreased sleep duration. PTSD and general mental health problems partially mediated the association between PTEs and DIMS. Youth in foster care are at high risk of sleep problems, related to traumatic experiences and mental health problems. Treatment of PTSD may improve sleep problems among maltreated youth.

Sleep difficulties in children with Tourette syndrome and chronic tic disorders: a systematic review of characteristics and associated factors.

Sleep difficulties are common in children and young people with Tourette syndrome and chronic tic disorders (TS/CTD). However, it is unclear whether sleep problems can be considered typical of the TS/CTD phenotype or whether they reflect concomitant factors such as individual patient characteristics (e.g. medication use), underlying neurodevelopmental disorders and/or co-occurring psychiatric symptoms. To help address this question, this review systematically explored types and frequency of sleep problems in children and young people with TS/CTD, while also examining the heterogeneity and methodological quality of studies. Psycinfo, Ovid Medline, Embase, and Web of Science databases were searched using a range of terms relating to tics, sleep and co-occurring psychopathology. Studies were considered that included a sample of children with TS/CTD (n > 5) for whom sleep difficulties were measured. Eighteen studies met criteria for inclusion in the review. Findings supported the high prevalence of sleep difficulties in children with TS/CTD, though estimates of sleep difficulties ranged from 9.7% to 80.4%. Twelve studies reported on other factors affecting sleep in this patient group including tic severity, comorbid psychopathological or neurodevelopmental disorders and medication use. Studies varied in terms of methodology, sample characteristics and research quality, but most concluded that children with TS/CTD experienced high levels of sleep difficulties with children with co-occurring anxiety most at risk. The current review highlights the need for further empirical investigation of sleep in children with TS/CTS, with a view to informing understanding and clinical management.

Posttraumatic Stress Disorder Severity and Insomnia-Related Sleep Disturbances: Longitudinal Associations in a Large, Gender-Balanced Cohort of Combat-Exposed Veterans.

Few studies have investigated the range and severity of insomnia-related sleep complaints among veterans with posttraumatic stress disorder (PTSD), and the temporal association between insomnia and PTSD severity has yet to be examined. To examine these associations, a large, gender-balanced cohort of veterans (N = 1,649) of the Iraq and Afghanistan conflicts participated in longitudinal assessments of PTSD and insomnia-related symptoms over a period of 2.5 years following enrollment (range: 2-4 years). Data were obtained from multiple sources, including interviews, self-report assessments, and electronic medical record data. Three-fourths (74.0%) of veterans with PTSD diagnoses at Time 1 (T1) reported insomnia-related sleep difficulties on at least half the nights during the past 30 days, and one-third of participants had received a prescription for a sedative-hypnotic drug in the past year. Veterans without PTSD had fewer sleep problems overall, although the prevalence of sleep problems was high among all study participants. In longitudinal, cross-lagged panel models, the frequency of sleep problems at T1 independently predicted increases in PTSD severity at Time 2 (T2), B = 0.27, p < .001, after controlling for gender and relevant comorbidities. Conversely, T1 PTSD severity was associated with increasing sleep complaints at T2 but to a lesser degree, B = 0.04, p < .001. Moderately high rates of sedative-hypnotic use were seen in veterans with PTSD, with more frequent use in women compared to men (40.4% vs. 35.0%). Sleep complaints were highly prevalent overall and highlight the need for increased clinical focus on this area.

Self-reported sleep quality and sleep disorders in people with physician-diagnosed gout: an Internet cross-sectional survey

BackgroundLimited information exists regarding sleep disorders in gout. Our objective was to assess the burden of sleep disorders in people with gout.MethodsA brief anonymized Internet survey of people with physician-diagnosed gout who visited a gout education website assessed the frequency of sleep problems, sleep quality over the past 24 h (0 = best possible sleep, 10 = worst possible sleep), daytime sleepiness on a typical day (0 = none and 10 = most sleepy during the day), sleep quantity (number of hours of sleep), and the frequency of snoring or gasping, and snorting or stopping breathing during the sleep, using validated questionnaires, including the NHANES 2016 sleep questionnaire. We used Chi-square test to compare the categorical and t test the continuous variables.ResultsOf the 454 website visitors who clicked the survey, 320 survey respondents reported physician-diagnosed gout. Mean age was 57 years (standard deviation [SD], 13.4), 72% were male, 77% were White, and mean gout duration was 7.6 (SD, 11). Of the respondents, 23% reported doctor-diagnosed sleep disorder (sleep apnea, 17%; sleep study ordered, diagnosis pending, 4%; other sleep disorder 2%). A mean 6.7 h of sleep per night was reported (SD, 1.3). Eighty-six percent reported snoring during sleep and 45% reported having snorted, gasped, or stopped breathing while asleep. Two thirds of the patients reported feeling sleepy during the day, at least 3–4 times a month or more. Sleep quality was 5.5 (SD, 2.6), and daytime sleepiness was 3.5 (SD, 2.6) on a 0–10 scale (higher = worse).ConclusionsPeople with physician-diagnosed gout reported frequent sleep disorders and daytime sleepiness in an Internet survey. More in-depth studies are needed to better understand the association of gout with sleep disorders.

Multimodal brain imaging investigation of self-reported sleep quality and daytime sleepiness in older adults with heart failure

ABSTRACTPurpose of the study: Individuals with heart failure (HF) have a high frequency of sleep problems. Patients with HF present with structural brain changes different from normal aging including reductions in brain volume, increases in white matter hyperintensity (WMH) and reduced cerebral blood flow. These structural changes in the brain may explain the pathophysiology of sleep and daytime problems. The objective of this study was to determine whether multimodal imaging data are related to self-reported sleep problems and daytime sleepiness in older adults with HF.Methods: Participants in this study underwent magnetic resonance imaging scans on the General Electric 3.0 T Discovery MR750 to acquire WMH, cerebral blood flow and brain volume. Data on 37 stable HF patients (mean age = 68; SD = 5.75) were included.Results: In this sample, WMH was associated with daytime sleepiness (p = 0.025). However, gray and white matter volume and cerebral blood flow were not associated with daytime sleepiness, sleep quality or insomnia.Conclusion: Although further studies are needed to determine the relationship between WMH and sleep and daytime problems, the findings preliminarily support that increases in WMH from ischemic changes could explain increases in daytime sleepiness among people with HF.

Relationship Between Sleep Problems and Quality of Life in Children With ADHD

Objective: The purpose of this study is to assess the sleep behaviors, sleep problems and frequency, and relationship with psychiatric comorbidities in ADHD Combined type and to evaluate the effect of sleep problems on quality of life. Method: Forty-six boys, aged 7 to 13 years, with ADHD-combined type and 31 healthy boys were included. ADHD children were never treated for sleep or psychiatric disorders. Intelligence quotient (IQ) test scores were minimum 80, body mass index were normal and did not have medical disorders. Parents completed Children’s Sleep Habits Questionnaire, Conners’ Parent Rating Scale and The Pediatric Quality of Life Inventory (PedsQL) and participants were asked about sleep behaviors and were administered PedsQL and Schedule for Affective Disorders and Schizophrenia. Results: The frequency of sleep problems in ADHD is 84.8%, higher than the control group (p = .002). Evaluating PedsQL scores, the quality of life is worse in physical, psychosocial health, and total life quality (p < .05). ADHD group with sleep problems have more night wakings than control group with sleep problems (p = .02). The comorbidity do not increase sleep problems. The frequency of parasomnias is increased in group with learning disorders (p = .05). Conclusion: The results of this study, which controls for a number of possible confounders found in previous examinations of ADHD and sleep, support the results of a number of other studies that have found an increased overall prevalence of parent-reported sleep disturbances in children with ADHD compared with healthy control participants. As the ADHD group have more night wakings than the control group through the night, it is thought that night wakings that cause a partitioned sleep may be important signs seen in ADHD. That could be suggested by two hypotheses. First one is that, daytime sleepiness is more common in ADHD and those children present excessive hyperactivity during the day to stay awake and the second one is the improvement of ADHD signs when the drugs for sleepiness are used. Usage of standardized and valid diagnostic criteria, exclusion of adolescence, gender, socioeconomic level, primary sleep problems, medical disorders and low IQ level, making allowances for effect of comorbidities and having compared with the control group are the important methodological features of this study. The most important limitation of this study is small sample size that makes the findings less generalizable to other groups of children with ADHD, and another one is not having used objective measurements together with subjective measurements. In conclusion, these results underscore the importance of screening all children who have a symptom constellation suggestive of ADHD for sleep problems that may either play a causative role or exacerbate the clinical appearance of ADHD in a given child. Correct evaluation and treatment of sleep problems increase the life quality of family and child and also decrease the severity of ADHD symptoms.

1673 – Evaluation of sleep and pain in newly diagnosed patients with generalised anxiety disorder (GAD): the espiga study

Introduction In the general population the 12-month prevalence of GAD is estimated to be about 2%. Higher prevalences have been found in primary care settings, with estimates of well over 6%. The role of sleep problems and pain in GAD remains understudied. Objectives To evaluate the frequency of sleep problems and pain in newly diagnosed GAD patients in 5 European countries. Methods Non-interventional, cross-sectional survey of 1650 adult patients newly diagnosed with GAD in primary care settings. Assessment included clinical interview rating and self report data. Results Mean age of the sample was 49.2 years (SD; 14.5). Mean GAD-7 score was 14.8 (SD; 3.1) and the median duration of symptoms was 12.0 months. The proportion with sleep disturbance and pain were 85.9% and 75.9%, respectively. Disturbed sleep had persisted for a median of 9.0 months and was mainly classified as “difficulty in falling asleep” (76.1%) or “nocturnal awakening” (58.8%). The median duration of pain was 6.0 months, and located mainly in the cervical region (47.0%) and upper back/limbs (40.1%). The mean number of days that patients were unable to work because of GAD-related health problems during the preceding 3 month period was 10.8 (95%CI; 9.6-12.0). The proportion of patients that visited the primary care physician and specialist during the preceding 3 months was 93.8% and 40.3%, respectively. Conclusions Sleep problems and pain are extremely frequent characteristics of GAD, contributing to the disability and work productivity profile associated with GAD as well as the patients’ use of health care resources.

Religious Doubts and Sleep Quality: Findings from a Nationwide Study of Presbyterians #090709revised

A growing literature examines the correlates and sequelae of spiritual struggles, such as religious doubts. To date, however, this literature has focused primarily on a handful of mental health outcomes (e.g., symptoms of depression, anxiety, negative affect), while the possible links with other aspects of health and well-being, such as poor or disrupted sleep, have received much less attention. After reviewing relevant theory and previous studies, we analyze data from a nationwide sample of Presbyterian Church (USA) members to test the hypothesis that religious doubts will be inversely associated with overall self-rated sleep quality, and positively associated with the frequency of sleep problems and the use of sleep medications. We also hypothesize that part of this association will be explained by the link between religious doubts and psychological distress. Results offer moderate but consistent support for these predictions. We end with a discussion of the implications of these findings, a brief mention of study limitations, and some suggestions for future research.

Caregiver Reports of Sleep Problems in Non-Hispanic White, Hispanic, and African American Patients with Alzheimer Dementia

Sleep problems are common in persons with dementing illnesses and among the most stressful patient behaviors for caregivers. Although studies have shown differences in sleep across ethnic groups, little information is available on ethnic differences among persons with dementia. The purpose of this study was to investigate possible ethnic differences in sleep problems among patients with Alzheimer dementia. Caregiver reports of 5 sleep- or circadian rhythm-related behavioral problems (behavior disturbance worse in the evening, difficulties falling asleep, frequent awakenings, early awakenings, and excessive daytime sleep) were evaluated in 395 patients who had received a diagnosis of Alzheimer disease after diagnostic evaluation. The average cognitive score of the groups suggested that they could be characterized as having moderately severe impairment. The frequency of sleep problems was then evaluated across subgroups defined by self-reported ethnicity (African American, Hispanic, and non-Hispanic white). As patient and caregiver characteristics may affect caregivers' reports of patients' behaviors, mixed effects regression models were used to adjust for patient and caregiver variables that might affect caregiver reports. Analyses revealed ethnic differences in sleep or circadian rhythm disturbances. African American and Hispanic patients were reported to have more severe sleep disturbances than non-Hispanic whites. After correction for patient and caregiver variables that might have affected caregiver reports, differences between African Americans and others remained. Sleep problems in patients with dementing illnesses are reported by caregivers with differing frequencies across groups of African Americans, Hispanics, and non-Hispanic whites. Clinicians should be aware of these differences in assessing sleep disturbance in patients with dementia as well as the potential effects of patient and caregiver variables on reports of these problems.
