“…25,26 Financial hardship could also reflect lower family socioeconomic status, which has been implicated in short and poor child sleep. 13 Maternal full-time work was also associated with persistent short sleep. Longer maternal work hours could promote short sleep by influencing family and child routines (eg, promoting later bedtimes) 27 or by increasing the mother' s risk of poor sleep, which subsequently affects their child' s sleep.…”

Distinct Developmental Trends in Sleep Duration During Early Childhood

WHAT'S KNOWN ON THIS SUBJECT: A limited number of studies have identified distinct patterns of child sleep duration, which appear to have implications for health and well-being. WHAT THIS STUDY ADDS:This article identifies distinct patterns of sleep duration during early childhood and demonstrates that these have important implications for health-related quality of life. abstract BACKGROUND AND OBJECTIVES: Sleep is important to child development, but there is limited understanding of individual developmental patterns of sleep, their underlying determinants, and how these influence health and well-being. This article explores the presence of various sleep patterns in children and their implications for healthrelated quality of life.METHODS: Data were collected from the Longitudinal Study of Australian Children. Participants included 2926 young children followed from age 0 to 1 years to age 6 to 7 years. Data on sleep duration were collected every 2 years, and covariates (eg, child sleep problems, maternal education) were assessed at baseline. Growth mixture modeling was used to identify distinct longitudinal patterns of sleep duration and significant covariates. Linear regression examined whether the distinct sleep patterns were significantly associated with health-related quality of life. RESULTS:The results identified 4 distinct sleep duration patterns: typical sleepers (40.6%), initially short sleepers (45.2%), poor sleepers (2.5%), and persistent short sleepers (11.6%). Factors such as child sleep problems, child irritability, maternal employment, household financial hardship, and household size distinguished between the trajectories. The results demonstrated that the trajectories had different implications for health-related quality of life. For instance, persistent short sleepers had poorer physical, emotional, and social health than typical sleepers. CONCLUSIONS:The results provide a novel insight into the nature of child sleep and the implications of differing sleep patterns for healthrelated quality of life. The findings could inform the development of effective interventions to promote healthful sleep patterns in children.

Association between sleep duration and overweight: the importance of parenting

OBJECTIVE: Sleep duration has been related to overweight in children, but determinants of sleep duration are unclear. The aims were to investigate the association between sleep duration and childhood overweight adjusted for family characteristics and unhealthy behaviours, to explore determinants of sleep duration and to determine with sleep competing activities. METHOD: A cross-sectional study was carried out in 2006 among 4072 children aged 4-13 years in the city of Zwolle, The Netherlands. In these children, data were available on measured height, weight and waist circumference, and from a parental questionnaire, on socio-demographic characteristics, child's sleep duration, nutrition, physical activity and sedentary behaviour. Associations were studied in 2011 using logistic and linear regression analyses, adjusted for potential confounders. RESULTS: Short sleep duration was associated with overweight for 4-8-year-old boys (odds ratio (OR):3.10; 95% confidence interval (CI):1.15-8.40), 9-13-year-old boys (OR:4.96; 95% CI:1.35-18.16) and 9-13-year-old girls (OR:4.86; 95% CI:1.59-14.88). Among 4-8-year-old girls no statistically significant association was found. Determinants for short sleep duration were viewing television during a meal, permission to have candy without asking, not being active with their caregiver and a late bedtime. For all children, short sleep duration was strongly associated with more television viewing and computer use. CONCLUSIONS: Association between sleep duration and overweight is not explained by socio-demographic variables, drinking sugared drinks and eating snacks. Parents have a key role in stimulating optimal sleep duration. Improving parenting skills and knowledge to offer children more structure, and possibly with that, increase sleeping hours, may be promising in prevention of overweight. INTRODUCTIONOver the past decades, there has been a growing interest in the relationship between sleep duration and high body weight. A large number of studies has shown an association between reduced sleep duration and childhood overweight, especially in young children. [1][2][3] The association between short sleep duration and overweight seems to be stronger for boys than girls, 4 although not all studies have reported a gender difference. 2 Possible explanations for the association between sleep duration and overweight include the role of behavioural and hormonal factors; short sleep leaves more time for eating, particularly snacking or drinking sugared drinks, and causes alterations in appetite-regulating hormones resulting in overeating. 1,2,5 Moreover, sleepiness may result in reduced physical activity and increased sedentary behaviour. 1,2,5 Determinants of short sleep duration have not yet been fully explored. Presumably, sleep duration is influenced by a combination of socio-demographic, behavioural and environmental factors. With regard to socio-demographic factors, children of Caucasian ethnicity have been indicated to sleep longer than children of other ethnicities. [6][7][8][9] ...

“…The reasons for short sleep duration in children and adolescents are likely multifactorial and include family, school, media use, and individual factors. 1 In this regard, inadequate sleep duration has been linked with obesity and atherogenic dyslipidemia in children and adolescents. [2][3][4] Blood pressure (BP) is an important marker of future health because elevated BP in childhood is associated with higher cardiovascular risk in later life.…”

WHAT'S KNOWN ON THIS SUBJECT: Inconsistent results have been reported on the association between sleep duration and blood pressure (BP) in children, likely as a result of inadequate adjustment for confounders and the use of different time frames in assessing sleep duration.WHAT THIS STUDY ADDS: Short sleep duration and poor sleep quality are associated with higher BP in normal-weight adolescents. One night of adequate sleep may partially ameliorate the risk of high BP but cannot completely reverse the effect of chronic sleep insufficiency. abstract OBJECTIVE: To evaluate the association between ambulatory blood pressure (ABP) and sleep duration as measured by 7-day sleep diary and nocturnal polysomnography in normal-weight adolescents without significant obstructive sleep apnea. METHODS:Subjects aged 10 to 17.9 years with an obstructive apnea hypopnea index ,5 underwent polysomnography for 9.5 hours and 24-hour ABP monitoring commencing at noon on the same day. ABP was divided into prepolysomnography, in bed during polysomnography, and postpolysomnography periods for separate analyses. Sleep duration (SpD 7 ) was obtained from a 7-day sleep diary, reflecting the sleep pattern in the week before admission. Total sleep time (TST) and sleep efficiency (SpE) were obtained from polysomnography. RESULTS:A total of 143 adolescents participated. SpD 7 was inversely associated with systolic blood pressure (SBP) in prepolysomnography, in-bed, and postpolysomnography periods (all b = 22 mm Hg) and with diastolic blood pressure (DBP) in prepolysomnography and in-bed periods (all b = 21 mm Hg). TST was inversely associated with SBP in the postpolysomnography period (b = 21.5 mm Hg). SpE was inversely associated with SBP in in-bed period (b = 20.1 mm Hg) and with DBP in in-bed (b = 20.1 mm Hg) and postpolysomnography (b = 20.2 mm Hg) periods. Neither TST nor SpE was associated with SBP and DBP in prepolysomnography period.CONCLUSIONS: Short sleep duration as reflected by 7-day sleep diary was associated with higher blood pressure in normal-weight adolescents. Occasional adequate sleep may partially ameliorate the risk of high blood pressure but may not completely reverse the effect of long-term sleep insufficiency. Pediatrics 2014;133:e64-e72
