Our goal was to identify characteristics associated with inadequate sleep for a national random sample of elementary school-aged children (6-11 years) and adolescents (12-17 years).
Data from 68418 participants in the 2003 National Survey of Children's Health were analyzed by using weighted bivariate and multivariate regression models. The dependent variable was report of not getting enough sleep for a child of his or her age >or=1 night of the past week. Independent variables included demographic characteristics, child health, school and other activities, and family life.
Parents of elementary school-aged children with inadequate sleep were more likely to report that their child was having problems at school or had a father with fair or poor health. Parents of adolescents with inadequate sleep were more likely to report that their child had an atopic condition, frequent or severe headaches, a parent with less-than-excellent emotional health, or experienced frequent parental anger. Inadequate sleep in both age groups was associated with parental report that their child usually or always displayed depressive symptomatology, family disagreements involved heated arguing, or parental concern that the child was not always safe at home, at school, or in their neighborhood.
Approximately 15 million American children are affected by inadequate sleep. Primary care providers should routinely identify and address inadequate sleep and its associated health, school, and family factors.
"Con toda la información recopilada, las variables estudiadas fueron: Patrones de descanso. Entendiendo como tales, –el mantenimiento de unos horarios regulares a la hora de acostarse y levantarse–, así como un número suficiente de horas de sueño (Smaldone, Honig y Byrne, 2007). Se distribuyeron los participantes en dos grupos. "
[Show abstract][Hide abstract] ABSTRACT: Las relaciones existentes entre el sueño y la vigilia, los ciclos de descanso y actividad, por una parte, y la práctica de la actividad física o deporte, por la otra, son muy complejas, intrincadas y multifactoriales en ambos sentidos (García-Mas, Aguado, Cuarto, Calabria, Jiménez y Pérez). Posiblemente influya en ello la diversidad de métodos usados tanto para la evaluación de los aspectos relacionados con el sueño como aquellos usados para la medida de la actividad física, con los consecuentes problemas de fiabilidad y validez mostrados en algunos de ellos. Entre otros, para la primera de las variables se han empleado los siguientes métodos: cuestionarios retrospectivos, la realización en laboratorios de sueño de polisomnografías y la actigrafía o actimetría; mientras que para la segunda variable, los métodos más usados han sido: cuestionarios auto-administrados, diarios auto-evaluados, colorimetría, monitorización electrónica o mecánica y observación conductual (García-Mas, Estrany y Cruz, 2004). Dormir es crucial para el aprendizaje de los niños y adolescentes (Dewald, Meijer, Oort, Kerkhof y Bógels, 2010). Atendiendo a su duración, sería necesario matizar la existencia de diferentes patrones de sueño: corto (una media de 6 horas o menos por noche), largo (más de 9 horas por noche) y medio (entre 6-9 horas por noche). Aún más, se podría añadir un cuarto tipo, referido a los sujetos con patrón de sueño variable que se caracterizarían por la inconsistencia de sus hábitos de sueño (Quevedo-Blasco y Quevedo-Blasco, 2011). Estos patrones ponen de manifiesto la gran cantidad de variaciones interindividuales, especialmente durante la infancia (Price, Brown, Bittman, Wake, Quach y Hiscock, 2014). Si bien no existe un número óptimo de horas de sueño que pueda generalizarse a todos los niños en edad escolar, los estudios muestran que la duración del sueño decrece gradualmente con la edad durante la etapa de primaria (Jenni, Molinari, Caflish y Largo, 2007). Actualmente hay suficiente evidencia empírica para recomendar que los niños de 5 a 10 años duerman un mínimo de 9-10 horas por la noche, a fin de que puedan mantener un adecuado estado de alerta durante el día (

"In a study that followed a large group of youth from birth to age 15, Meldrum et al. (2013) illustrated that sleep deprivation was associated with low self-control, which in turn was related to delinquency. Finally, in a comprehensive study with over 64,000 child and adolescent participants, Smaldone et al. (2007) reported that inadequate sleep was associated with a variety of mental and physical health symptoms, including frequent or severe headaches and depressive symptoms. Collectively, these studies illustrate robust associations between sleep difficulties and mental and physical health. "
[Show abstract][Hide abstract] ABSTRACT: Exposure to violence is associated with elevated levels of sleep problems in adolescence, which contributes to poor mental and physical health and impaired academic performance. However, reasons underlying the associations between exposure to violence and sleep difficulty have not been examined. This study tested a social cognitive processing path model linking experiences of witnessing and directly experiencing community violence and sleep problems. Participants were 362 early adolescents (M age = 12.45 years, SD = 0.59; range 11-14 years; 48.9 % male; 51 % Latino/a; 34 % black) from urban communities enrolled in a middle-school-based intervention study on the east coast of the United States that was designed to reduce the negative effects of exposure to violence. All youth in the current study reported witnessing or directly experiencing community violence. Adolescents completed four school-based assessments over an 18-month period, reporting on their exposure to community violence, sleep problems, intrusive thoughts about and social constraints in talking about violence, and life events. A path model that included both victimization and witnessing violence revealed that wave 1 witnessing violence, but not victimization, was associated with elevated social constraints in talking about violence at wave 2, which was associated with elevated intrusive thoughts at wave 3, which was associated with poor sleep quality at wave 4. Prior levels of all constructs were controlled in the analysis, in addition to life events, single parent household status, children's age and sex, intervention condition, and school. Youth exposed to violence may benefit from help in processing their experiences, thus reducing social constraints in talking about their experiences and associated intrusive thoughts. This is turn may improve sleep outcomes.

"Previous studies have suggested that the influential factors associated with sleep duration among adolescents included demographic factors, family environments, lifestyle patterns, sociocultural conventions, health status, and school schedules       . "
[Show abstract][Hide abstract] ABSTRACT: Objective
To examine sleep-duration-related risk factors from multidimensional domains among Chinese adolescents.
A random sample of 4801 adolescents aged 11–20 years participated in a cross-sectional survey. A self-reported questionnaire was used to collect information about adolescents' sleep behaviors and possible related factors from eight domains.
In all, 51.0% and 9.8% of adolescents did not achieve optimal sleep duration (defined as <8.0 h per day) on weekdays and on weekends, respectively. According to multivariate logistic regression models, after adjusting for all possible confounders, 17 factors were associated with sleep duration <8 h. Specifically, 13 factors from five domains were linked to physical and psychosocial condition, environment, and behaviors. These factors were overweight/obesity, chronic pain, bedtime anxiety/excitement/depression, bed/room sharing, school starting time earlier than 07:00, cram school learning, more time spent on homework on weekdays, television viewing ≥2 h/day, physical activity <1 h/day, irregular bedtime, and shorter sleep duration of father.
Biological and psychosocial conditions, sleep environments, school schedules, daily activity and behaviors, and parents' sleep habits significantly affect adolescents' sleep duration, indicating that the existing chronic sleep loss in adolescents could be, at least partly, intervened by improving adolescents' physical and psychosocial conditions, by controlling visual screen exposure, by regulating school schedules, by improving sleep hygiene and daytime behaviors, and by changing parents' sleep habits.
