Longitudinal associations between parent, child, family factors and dyssomnias in children from birth to 8 years: The CIKEO study. J Affect Disord 2023; 323:496-505. [PMID: 36513160 DOI: 10.1016/j.jad.2022.12.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 11/23/2022] [Accepted: 12/04/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Dyssomnias, are the most common parent-reported sleep complaints in young children. The present study investigated the prevalence, one-year development (incidence and persistence) of dyssomnia in early childhood, and the parent, child, and family factors associated with dyssomnia. METHODS Longitudinal data of 700 children aged 0-8, gathered in the CIKEO cohort study in the Netherlands were analyzed. Dyssomnias were defined as the presence of night awakenings ≥3 times per night or sleep-onset latency of >30 min. Least absolute shrinkage and selection operator (LASSO) was used to identify the parental, child, and family factors associated with the incidence and persistence of dyssomnias in children. RESULTS The mean age of the children (47 % girls) was 3.2 ± 1.9 years at baseline and 4.4 ± 1.8 years at follow-up. The prevalence of dyssomnias was 13.3 % and 15.4 % at baseline and follow-up, respectively. The incidence and persistence rates of dyssomnias at follow-up were 12.0 % and 37.6 %, respectively. New incidence of insomnia was associated with being a girl, having medical conditions, experiencing stressful life events, and lower parenting self-efficacy at baseline (P < 0.05). Higher levels of parental psychological distress were associated with the persistence of dyssomnias in children (P < 0.05). CONCLUSIONS Dyssomnias are common with a moderate persistent rate in young children. Several parental, child, and family factors in relation to the incidence and persistence of dyssomnias were identified. Preventive programs and interventions targeting modifiable factors, particularly parental psychological distress, parenting self-efficacy, and resilience to stressful life events, might benefit child sleep.

Abstract
STUDY OBJECTIVES To investigate trajectories of early childhood sleep in the first 3 years and their association with maternal depressive symptoms. METHODS Data were from 243 Chinese mother-child dyads. Children's sleep duration and night-waking were assessed using the Brief Infant Sleep Questionnaire (BISQ) at 42 days, 3, 6, 9, 12, 18, 24, and 36 months postpartum. The Center for Epidemiological Survey-Depression Scale (CES-D), Edinburgh Postnatal Depression Scale (EPDS), and Profile of Mood States (POMS) were used to assess maternal depressive symptoms at late pregnancy, 42 days, and 36 months postpartum, respectively. Early childhood sleep trajectories were estimated with group-based trajectory models. The association between early childhood sleep trajectories and maternal depressive symptoms was examined with binary and multinomial logistic regression models and linear regression models. RESULTS Three trajectories of daytime sleep duration ("short", 14.4%; "medium", 60.4%; "long", 25.2%), nighttime sleep duration ("increasing", 17.6%; "stable", 76.3%; "decreasing", 6.1%), and total sleep duration ("short", 21.5%; "medium", 59.9%; "long",18.6%), and two trajectories of night-waking ("resolving", 22.9%; "persistent", 77.1%) were identified. Controlling for confounding factors, maternal depression at 42 days postpartum was associated with higher risks for short daytime sleep duration and persistent night-waking in children. Persistent night-waking in children was associated with increased maternal depressive symptoms at 36 months postpartum. CONCLUSION Early childhood sleep follows distinct trajectories in the first 3 years of life. The trajectories of short daytime sleep duration and persistent night-waking are associated with maternal depression. The findings indicate tailored interventions should target both unfavorable early childhood sleep trajectories and maternal depression.

Abstract
OBJECTIVES To investigate the current status of sleep initiation patterns, influencing factors for sleep initiation patterns, and the influence of sleep initiation patterns on sleep quality in infants and young children. METHODS A total of 521 infants and young children, aged 0-35 months, who underwent physical examination at the outpatient service of the Department of Growth and Development in Shenzhen Bao'an Women's and Children's Hospital Affiliated to Jinan University were enrolled as subjects. A self-designed questionnaire and Brief Infant Sleep Questionnaire were used to collect the information on family background, parenting behaviors, and sleep quality in the past one week. A multivariate logistic regression analysis was used to evaluate the influencing factors for sleep initiation patterns. A multiple linear regression analysis was used to evaluate the influence of sleep initiation patterns on the number of nighttime awakenings. RESULTS Among the 521 infants and young children, 258 (49.5%) were breastfed/bottle fed to initiate sleep, 62 (11.9%) were rocked/held to initiate sleep, 39 (7.5%) slept independently, and 162 (31.1%) initiated sleep accompanied by parents. The multivariate logistic regression analysis showed that the children with breastfeeding and a younger age were more likely to be breastfed/bottle fed to initiate sleep (P<0.05) and that the children with a younger age were also more likely to be rocked/held to initiate sleep (P<0.05). The multiple linear regression analysis showed that sleep initiation with breastfeeding/bottle feeding significantly increased the number of nighttime awakenings (P<0.05). CONCLUSIONS Most infants and young children initiate sleep by being breastfed/bottle fed, rocked/held, or accompanied. The sleep initiation pattern is associated with the age of children and whether they are still breastfeeding. Sleep initiation with breastfeeding/bottle feeding can increase the number of nighttime awakenings. io.

Abstract
The present study examined bidirectional effects between sleep problems (nocturnal awakenings and insufficient nocturnal sleep) and infant development (gross motor, fine motor, and cognition) in a sample of 182 infants (89 girls) and their parents living in Beijing (China). Using 3 waves of longitudinal data (at 6 months, 1 year, and 2 years of age), this study (a) explored the differences in sleep patterns and developmental outcomes between infants in the current sample and infants from other cultures; and primarily examined (b) whether nocturnal awakenings and insufficient nocturnal sleep prospectively predicted infant development; (c) or whether infant development predicted sleep problems. Mothers reported their children's sleep problems, and infant development was assessed with Bayley III. Sleep patterns of Beijing infants were slightly different from those from Finland and Singapore, and most scores on Bayley III in this Beijing sample were higher than those in Danish, Dutch and Sri Lankan samples. Sleep problems and developmental measures were stable across the 3 times of assessments, but cross-lagged associations were limited in number and strength. High scores on the Bayley at 6 months predicted less nocturnal awakenings at 1 year of age. Insufficient nocturnal sleep at 1 year predicted poor fine motor development at 2 years. Thus, findings suggest some bidirectional associations between infant development and sleep problems and further highlight the need to understand these relations within specific cultural contexts.

Abstract
In infants and young children, bedtime problems and night waking are common and the main presentations of insomnia. Poor sleep may critically impact the daytime functioning and mood of the child and their caregivers. A comprehensive sleep history, a sleep diary/log, and the BEARS (Bedtime problems, Excessive daytime sleepiness, Awakenings during the night, Regularity and duration of sleep, and Sleep-disordered breathing) sleep screen are useful for diagnosing sleep problems in young children. Behavioral therapies for this type of insomnia include extinction, bedtime fading with positive routines, and scheduled awakening. Previous studies of behavioral interventions for young children showed significant improvements in sleep-onset latency, night waking frequency, and night waking duration. Parent education about their child's sleep, bedtime routines, and sleep hygiene is essential for treatment.

Abstract
OBJECTIVE Infant sleep plays a critical role in normal development. Sleep problems, including sleep onset difficulties (SODs) and night waking (NW), range from 20% to 30% in infants and young children and can be persistent over time up to adulthood. Young French children seem to have longer sleep durations and less sleep troubles than their counterparts worldwide. Here, we aimed at describing infant sleep characteristics (total sleep time (TST)/24 h, NW, and SODs) and associated sleep habits in infants at age one year from the French nationwide birth cohort Etude Longitudinale Française depuis l'Enfance (ELFE). METHODS This study included 11,783 infants with information on both sleep characteristics and sleep habits (parental presence when falling asleep, eating to fall asleep, sucking a pacifier or finger to sleep and sleep arrangement and location). Associations were studied by multinomial logistic regression analyses adjusted for familial and infant characteristics. RESULTS Mean TST was 13 h36 min including 2 h54 min of naps; 20% of the infants had TST ≤12 h/24 h. About 46% did not present SOD or NW, 16% had frequent SODs and 22% had NW > 1 night in 2. Parental presence, feeding to fall asleep and infant sleep arrangements were frequent in infants with short sleep duration (≤12 h/24 h), NW and SODs. Non-nutritive sucking was associated with risk of NW, SOD and TST >14 h/24 h. Parental room sharing was associated with NW. CONCLUSION This work provides new information on infant sleep arrangements and non-nutritive sucking that should be accounted for when considering sleep behaviors. In addition, most identified sleep habits associated with poor sleep characteristics may be amenable to change.

Abstract
BACKGROUND AND OBJECTIVES Optimal sleeping habits are important for health development of infants. The role of culture in sleep habits cannot be underestimated. We aimed to characterize sleep patterns, sleep practices, and sleep problems; and assess the sleep settings and parental perceptions of sleep problems in children from birth to 36 months in countries in the Southeast Asian (SEA) region. PARTICIPANTS Parents and caregivers of infants and toddlers (birth to 36 months old) from countries in Southeast Asia participated in this study. METHODS Data was collected using the Brief Infant Sleep Questionnaire for a total of 5,987 children from 6 countries in the SEA region (967 Indonesia/ID, 997 Malaysia/MY, 1,034 Philippines/PH, 1,001 Singapore/SG, 988 Thailand/TH, and 1,000 Vietnam/VN). RESULTS The sleep variables varied among SEA children studied. Bedtimes and nighttime sleep varied across the region by as much as 1 hr 34 min and 1 hr 15 min respectively. CONCLUSIONS Despite being geographically very close together and having some common sociocultural characteristics, sleep variables in the young child within the SEA region do differ in significant ways.

Abstract
STUDY OBJECTIVES To examine the prevalence and correlates of nighttime awakenings and to explore the association between sleep and cognitive development in a community sample of infants and toddlers. METHODS A total of 590 healthy infants (aged 2-11 months) and 512 toddlers (aged 12-30 months) from 8 provinces of China were assessed for their sleep and cognitive development. Data on sleep duration and nighttime awakenings were collected through the Brief Infant Sleep Questionnaire. Cognitive development was assessed by trained pediatricians using the Bayley Scales of Infant Development. RESULTS Prevalence of no nighttime awakening, and nighttime awakening(s) for 1×/night, 2×/night, and ≥ 3×/night was 6.8%, 20.2%, 33.2%, and 39.3% in infants, and was 25.8%, 34.6%, 23.8%, and 15.8% in toddlers, respectively. Nighttime awakenings were generally associated with younger age, lower maternal education level, and being currently breastfed. In addition, nighttime awakenings were associated with being boys in toddlers. After controlling for potential confounders, infants with nighttime awakenings for 2×/night were found to have significantly higher Mental Development Index (MDI) score, as compared to those without and those with more frequent nighttime awakenings. However, toddlers with nighttime awakenings for ≥ 3×/night had significantly lower MDI, as compared to those with fewer nighttime awakenings. Total sleep duration was not associated with any developmental indices in both infants and toddlers. CONCLUSIONS Frequent nighttime awakenings are associated with poor cognitive functions in toddlers. Meanwhile, a nonlinear association between nighttime awakenings and cognitive performance was found among infants. The findings provide a developmental context for the effect of sleep on cognitive abilities in young children. Further longitudinal studies and interventional studies on the effects of parent-based sleep-focused intervention on cognitive abilities among young children are warranted.

Abstract
OBJECTIVES Adequate sleep in childhood is important for healthy development. No information exists on the predictors of night-time sleep among toddlers in Canada. The aim of this study was to determine the prevalence of and to identify factors associated with sleeping <11 consecutive hours per night among children aged 1-2 years in Canada. METHODS Data from the cross sectional Survey of Young Canadians (SYC) 2010 were used. The biological mother reported on toddlers' sleep duration at night. Based on cut-off values used in previous studies, shorter night-time sleep was defined as sleeping <11 hours per night. Multivariable logistic regression was conducted to identify the associations between socio-demographic, maternal, sleep and child-related variables with shorter sleep at night. RESULTS Analysis of 3675 toddlers revealed that 57% slept <11 hours per night. Results of the regression analysis showed that being from an immigrantfamily was significantly associated with shorter night-time sleep. Being from a higher income household, having a mother aged between 25 and 34 years at the time of the survey, and napping ≥2 hours during the day were significantly related to sleeping ≥11 hours per night. Other socio-demographic, maternal and child-related variables were not associated with night-time sleep. CONCLUSION This was the first population-based, nationally representative study to examine factors related to shorter night-time sleep in Canadian toddlers. Socio-demographic factors and nap duration were associated with night-time sleep duration. More adequate early childhood sleep hygiene awareness efforts are recommended, especially in vulnerable populations.

Abstract
BACKGROUND To describe the sleep patterns of children below 36 months in Hong Kong, and evaluate the associations between parental behaviors and childhood sleep/wake patterns. METHODS Parents of 1049 infants and toddlers completed an internet-based expanded version of the Brief Infant Sleep Questionnaire. RESULTS Total sleep duration (P<0.001), frequency (P<0.001) and duration (P<0.001) of nocturnal awakenings decreased with age, whereas the longest sleep duration (P<0.001) and nocturnal sleep duration (P<0.001) increased with age. Children who room- or bed-shared with parents had later bedtimes (P<0.001), but similar sleep duration compared with those who had a separate sleep location. Falling asleep independently was associated with longer nocturnal sleep duration (P<0.001) and less sleep awakenings (P<0.001). Full-time employment of parents was associated with shorter total sleep duration of children (P<0.001). Although breastfeeding was associated with more nocturnal awakenings (P<0.001), no association was detected between breastfeeding and shorter sleep duration in children. CONCLUSIONS As infants and toddlers develop, their sleep consolidates. Falling asleep independently was associated with longer nocturnal sleep duration and fewer sleep awakenings, whereas sleep location was not. This is an important finding, especially for families with limited living space where parent/child room- or bed-sharing cannot be avoided.

Abstract
Background Substantial progress in reducing the child mortality rate has been made globally in the last two decades. However, for China, the number of children dying from preventable diseases is still very large. It is important to have regularly updated information on the distribution of causes of death (COD) in children to inform policy and research. In this study, we aim to estimate the COD spectrum in children younger than five years old from 2009 to 2015 with a focus on the year 2015 and to provide an updated COD prediction model for China. Methods Updated data of under–five mortality rates (U5MRs) and the number of live births at national and provincial levels were obtained from United Nation's Inter–agency Group for Child Mortality Estimation (UN IGME), Institute for Health Metrics and Evaluation (IHME), and United Nations Population Division (UNPD). Then, we conducted a systematic review across four Chinese and English bibliographic databases and identified high–quality community–based longitudinal studies of COD in children younger than five years in China. We developed a number of single–cause models to predict the number of child death for main COD in different age groups at both national and provincial levels. The jackknife procedure was applied to construct the 95% Uncertainty Ranges (URs). Results From 2009 to 2015, the under–five mortality rates have declined by 37.1%. The leading causes of death in 2015 were preterm birth complications (17.4%), birth asphyxia (15.2%), congenital abnormalities (14.1%), accidents (13.5%) and pneumonia (12.4%) for children under five years old. The COD spectrum varied substantially across Chinese provinces with different development levels. The leading cause in children under five years in the wealthier provinces (with lower U5MRs) was congenital abnormalities (up to 18.9%), while in the poorer provinces (with higher U5MRs), pneumonia was the dominant COD (up to 23.4%). Conclusions This study updates and validates the accuracy of the findings of our previous COD study and proposes a new modelling method to predict proportions for the most common causes of child death in China. These updated COD estimates suggest that current strategies to reduce child mortality should prioritise action on neonatal deaths and target interventions against the top COD according to the local COD spectrum. Special attention should also be given to reducing differences between Chinese provinces and regions with differing development levels.

Parent-child bed-sharing: The good, the bad, and the burden of evidence. Sleep Med Rev 2016; 32:4-27.

Abstract
The practice of parent and child sharing a sleeping surface, or 'bed-sharing', is one of the most controversial topics in parenting research. The lay literature has popularized and polarized this debate, offering on one hand claims of dangers, and on the other, of benefits - both physical and psychological - associated with bed-sharing. To address the scientific evidence behind such claims, we systematically reviewed 659 published papers (peer-reviewed, editorial pieces, and commentaries) on the topic of parent-child bed-sharing. Our review offers a narrative walkthrough of the many subdomains of bed-sharing research, including its many correlates (e.g., socioeconomic and cultural factors) and purported risks or outcomes (e.g., sudden infant death syndrome, sleep problems). We found general design limitations and a lack of convincing evidence in the literature, which preclude making strong generalizations. A heat-map based on 98 eligible studies aids the reader to visualize world-wide prevalence in bed-sharing and highlights the need for further research in societies where bed-sharing is the norm. We urge for multiple subfields - anthropology, psychology/psychiatry, and pediatrics - to come together with the aim of understanding infant sleep and how nightly proximity to the parents influences children's social, emotional, and physical development.

Abstract
The purpose of this study was to examine sleep patterns in a large sample of infants and toddlers (ages birth to 36 months) in Korea, and to compare sleep patterns, sleep problems, sleep ecology, and parental behaviors to global sleep data on young children in both predominantly Asian (P-A) and predominantly Caucasian (P-C) countries/regions. We additionally examined parent and child demographic information, parental behaviors, and aspects of the sleep ecology as predictors of sleep patterns among infants and toddlers in Korea. Parents/caregivers of 1,036 Korean infants and toddlers completed an expanded, internet-based version of the brief infant sleep questionnaire. Consistent with other studies of sleep in early childhood, sleep/wake patterns became increasingly consolidated with older child age for the Korea sample. Compared to both P-A and P-C infants and toddlers, children in Korea had the latest bedtimes, shortest total sleep and daytime sleep durations, and the least frequent rates of napping. Even though half of parents perceive their children's sleep problematic, parental perceptions of severe child sleep problems were the lowest. Within Korea, breastfeeding and bottle-feeding at sleep resumption were associated with increased nocturnal awakenings. Evening television viewing was associated with later bedtimes, which may have implications for sleep hygiene recommendations in clinical practice. The current study provides important information about sleep/wake patterns, parental behaviors, and aspects of the sleep ecology for infants and toddlers for physicians to support healthy sleep in Korea.

Abstract
OBJECTIVE To investigate the prevalence of bed-sharing and examine correlates of bed-sharing habits in early adolescents. METHODS Participants were 1452 early adolescents from 10 primary schools in Shanghai, China. Children's health status and past history, family environment and parents' attitude towards bed-sharing, and children's sleep arrangements were surveyed. Sleep was assessed by the Children's Sleep Habit Questionnaire. Tanner stage was determined by the endocrinologist. RESULTS The median of age was 10.83 years (range: 9.42-12.92; 95% confidence interval [CI]: 10.79-10.83) and boys accounted for 51.17%. The prevalence of bed-sharing was 16.8%. Positive parental attitude toward bed-sharing (OR: 9.87; 95% CI: 6.57-14.83), asthma (OR: 2.15; 95% CI: 1.16-3.98), smaller residential space (OR: 1.90; 95% CI: 1.17-3.09), extended family (OR: 1.59; 95% CI: 1.16-2.18), and being physically less mature (OR: 2.39; 95% CI: 1.16-4.91) increased the likelihood of bed-sharing. Bed-sharers were more likely to have bedtime resistance (OR: 12.20; 95% CI: 8.59-17.33), sleep anxiety (OR: 3.76; 95% CI: 2.74-5.15), and poor sleep quality (OR: 3.21; 95% CI: 2.28-4.81) compared to non-bed-sharers. Furthermore, bed-sharing was associated with daytime sleepiness (OR: 1.53; 95% CI: 1.10-2.13) but not with sleep duration. CONCLUSIONS Bed-sharing is highly prevalent among Chinese early adolescents and is significantly related to sleep quality. Parental positive attitude toward bed-sharing was the most determining factor.

Abstract
OBJECTIVE Co-sleeping is associated with disturbance of the natural sleep pattern, including sleep fragmentation and daytime sleepiness. Nocturnal enuresis (NE) or bed-wetting, although benign, is a significant cause of distress to affected children and their caregiver(s). This study investigated the relationship between co-sleeping and NE in primary school children from China. METHODS Data from a previous sleep study of primary school children from 8 cities across China were analyzed. Multivariable regression analysis was performed to assess the relationship between co-sleeping and NE while controlling for a number of confounding factors. The prevalence of NE in co-sleeping and non-co-sleeping children in different age groups was evaluated. RESULTS The prevalence of co-sleeping and NE in children aged 5 to 12 years was 22.8% and 4.6%, respectively. Co-sleeping was associated with a higher prevalence of NE in primary school age children (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.27-1.77; p < .001) after adjusting for confounding factors. The differences in the prevalence of NE between co-sleepers and non-co-sleepers were significant in the 9-year age group (OR, 1.49; 95% CI, 1.06-2.11; p = .025) and 11- to 12-year age group (OR, 3.16; 95% CI, 2.19-4.57; p < .001). CONCLUSION Co-sleeping may increase the risk of NE in primary school children, particularly in those aged 11 to 12 years.

Abstract
OBJECTIVE The study aimed to (1) characterize sleep patterns and sleep disturbances among Chinese school-aged children, (2) determine the prevalence of their short sleep duration and sleep disturbances based on clinical cutoffs, and (3) examine possible factors (socio-demographic factors and emotional/behavioral problems) that are associated with sleep disturbances. METHODS A large representative sample of 912 children aged 6-14years was recruited from Shenzhen, China. Their parents completed the Children's Sleep Habits Questionnaire (CSHQ) and the Strengths and Difficulties Questionnaire (SDQ). RESULTS The mean bedtime was 9:45pm (SD=1h 11min), mean wake-up time was 7:03am (SD=31min), mean sleep duration was 9h 14min (SD=46min), and 23.8% of the children had sleep duration <9h. Overall, 69.3% of the children suffered from global sleep disturbances (CSHQ total score >41). Bedtime resistance (22.9%), sleep anxiety (22.1%), sleep duration (21%) and daytime sleepiness (20%) were the most prevalent sleep disturbances; followed by sleep disordered breathing (12.1%), parasomnias (9.4%), sleep onset delay (6.9%), and night waking (5.2%). The prevalence of specific sleep disturbances ranged from 3.2% (falling asleep while watching television) to 81.9% (awakening by others in the morning). Correlations between most domains of sleep disturbances and emotional/behavioral problems were statistically significant (p<0.05 or p<0.01). Hierarchical multiple regression analysis revealed that gender (β=0.10, p<0.01), school grade (β=-0.09, p<0.05), co-sleeping (β=0.25, p<0.01), emotional symptoms (β=0.24, p<0.01), conduct problems (β=0.09, p<0.05), and hyperactivity (β=0.17, p<0.01) accounted for significant variance in CSHQ total score. CONCLUSIONS Short sleep duration and sleep disturbances are prevalent among Chinese school-aged children. Sleep disturbances are associated with gender, school grade, co-sleeping, emotional symptoms, conduct problems, and hyperactivity.

Abstract
BACKGROUND A recent international Internet-based study of young children (birth to 36 months) found that total sleep duration in Japan was the shortest among 17 countries/regions. The present study compared features of children's sleep in Japan relative to those in other Asian countries/regions. METHODS Parents of 872 infants and toddlers in Japan (48.6% boys), and parents of 20 455 infants and toddlers in 11 other Asian countries/regions (48.1% boys; China, Hong Kong, India, Indonesia, Korea, Malaysia, Philippines, Singapore, Taiwan, Thailand, and Vietnam) completed an Internet-based expanded version of the Brief Infant Sleep Questionnaire. RESULTS Young children in Japan exhibited significantly fewer nocturnal wakings and shorter daytime sleep in comparison with other Asian countries/regions. Although the former finding was apparent in all age groups, the reduced duration of daytime sleep in Japan was not present until after 3 months of age. Interestingly, sleep problems were reported by significantly fewer parents in Japan compared with those in other Asian countries/regions, although parents in Japan reported significantly more difficulty at bedtime. CONCLUSIONS The short sleep duration of young children in Japan is largely due to a relatively short duration of daytime sleep. Significant differences in sleep characteristics in Japan relative to other Asian regions were found primarily after 3 months of age. Future studies should further explore the underlying causes and the potential impacts of these sleep differences.

Abstract
BACKGROUND AND OBJECTIVES Co-sleeping (bed or room sharing) has potential implications for children's development. Previous studies showed that co-sleeping was more prevalent in non-Western countries than in Western countries, which demonstrated that co-sleeping was marked with ethnic and socio-cultural background characteristics. The purpose of this study was to survey the prevalence of bed and room sharing and to examine related factors among school-aged children in an Asian country - China. METHODS A cross-sectional questionnaire survey was conducted in 10 districts of Shanghai, China from November to December 2005. A total of 4108 elementary school children, 49.2% boys and 50.8% girls with a mean age of 8.79 years, participated. Parent-administered questionnaires were used to collect information about children's sleeping arrangements and socio-demographic characteristics. RESULTS The prevalence of routine bed sharing, room sharing and sleeping alone in Chinese school-aged children was 21.0%, 19.1% and 47.7%, respectively. Bed and room sharing didn't show significant gender difference but gradually decreased with increasing age. Multivariate logistic regression identified those factors associated with bed and room sharing: younger age, large family, children without their own bedroom and parents' approval of a co-sleeping arrangement. CONCLUSION Co-sleeping arrangement was a common practice in Chinese school-aged children. Associated factors were characterized by intrinsic socio-cultural values and socio-economic status in China.

Abstract
Studies indicate that sleep problems in children and adolescents are highly prevalent, with prevalence rates ranging from 25% to 40%. They are even more common in special populations, especially children with psychiatric issues. Furthermore, sleep issues are often persistent. Unfortunately, sleep disturbances often do not receive the attention that they deserve, especially since they are often highly amenable to intervention. Sleep problems, in general, range from those that are physiologically-based, such as obstructive sleep apnoea and restless legs syndrome, to those that are behaviorally-based. The behaviourally-based sleep disorders are reviewed, including a discussion of assessment, prevalence and treatment. Non-pharmacologic approaches are usually the preferred treatment and have received the most empirical support in paediatric populations. It is strongly recommended that all paediatric healthcare providers consider sleep issues in their comprehensive assessment of all children and adolescents, especially those with psychiatric issues, and provide preventive education as part of their usual standard of care.
