Study objectives To present psychometric data on a comprehensive, parent-report sleep screening instrument designed for school-aged children, the Children's Sleep Habits Questionnaire (CSHQ). The CSHQ yields both a total score and eight subscale scores, reflecting key sleep domains that encompass the major medical and behavioral sleep disorders in this age group. Design Cross-sectional survey. Setting Three elementary schools in New England, a pediatric sleep disorders clinic in a children's teaching hospital. Participants Parents of 469 school-aged children, aged 4 through 10 years (community sample), and parents of 154 patients diagnosed with sleep disorders in a pediatric sleep clinic completed the CSHQ. Interventions N/A. Measurements and results The CSHQ showed adequate internal consistency for both the community sample (p=0.68) and the clinical sample (p=0.78); alpha coefficients for the various subscales of the CSHQ ranged from 0.36 (Parasomnias) to 0.70 (Bedtime Resistance) for the community sample, and from 0.56 (Parasomnias) to 0.93 (Sleep-Disordered Breathing) for the sleep clinic group. Test-retest reliability was acceptable (range 0.62 to 0.79). CSHQ individual items, as well as the subscale and total scores were able to consistently differentiate the community group from the sleep-disordered group, demonstrating validity. A cut-off total CSHQ score of 41 generated by analysis of the Receiver Operator Characteristic Curve (ROC) correctly yielded a sensitivity of 0.80 and specificity of 0.72. Conclusions The CSHQ appears to be a useful sleep screening instrument to identify both behaviorally based and medically-based sleep problems in school-aged children.

Pediatric Gastroesophageal Reflux Clinical Practice Guidelines: Joint Recommendations of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN)

Pediatric obstructive sleep apnea (OSA) has become widely recognized only in the last few decades as a likely cause of significant morbidity among children. Many of the clinical characteristics of pediatric OSA, and the determinants of its epidemiology, differ from those of adult OSA. We systematically reviewed studies on the epidemiology of conditions considered part of a pediatric sleep-disordered breathing (SDB) continuum, ranging from primary snoring to OSA. We highlight a number of methodologic challenges, including widely variable methodologies for collection of questionnaire data about symptomatology, definitions of habitual snoring, criteria for advancing to further diagnostic testing, and objective diagnostic criteria for SDB or OSA. In the face of these limitations, estimated population prevalences are as follows: parent-reported “always” snoring, 1.5 to 6%; parent-reported apneic events during sleep, 0.2 to 4%; SDB by varying constellations of parent-reported symptoms on questionnaire, 4 to 11%; OSA diagnosed by varying criteria on diagnostic studies, 1 to 4%. Overall prevalence of parent-reported snoring by any definition in meta-analysis was 7.45% (95% confidence interval, 5.75–9.61). A reasonable preponderance of evidence now suggests that SDB is more common among boys than girls, and among children who are heavier than others, with emerging data to suggest a higher prevalence among African Americans. Less convincing data exist to prove differences in prevalence based on age. We conclude by outlining specific future research needs in the epidemiology of pediatric SDB.

Epidemiology of pediatric obstructive sleep apnea

Few data currently exist concerning the sleep problems of preadolescents. A parent report questionnaire concerning sleep habits and problems was developed. The questionnaires were completed by the parents of 1000 unscreened elementary school children attending the third, fourth, and fifth grades. The schools were randomly selected from an urban area. Of the 1000 questionnaires, 972 were completed and could be used for statistical analysis. Among the parents, 24% reported sleeping poorly and 12% regularly relied on sedatives to induce sleep. Sleep difficulties lasting more than 6 months were present in 43% of the children. In 14% (132 of 972), sleep latency was longer than 30 minutes, and more than one complete arousal occurred during the night at least two nights per week. The following variables were seen among the poor sleepers: lower parental educational and professional status, parents who were more likely to be divorced or separated, and more noise or light in the rooms were they slept. They also presented a higher incidence of somnambulism, somniloquia, and night fears (nightmares and night terrors) than the children who slept well. Boys who slept poorly were significantly more likely to have insomniac fathers (P less than .010). Regular use of sedatives was described in 4% (5 of 132) of the children who slept poorly. Among the "poor sleepers," 21% (33 of 132) had failed 1 or more years at school. School achievement difficulties were encountered significantly more often among the poor sleepers than among the children without sleep problems (P = .001). Of the families with children suffering from sleep problems, 28% expressed a desire for counseling.(ABSTRACT TRUNCATED AT 250 WORDS)

Sleep problems in healthy preadolescents

Posttraumatic stress disorder after dog bites in children.

Objective. To evaluate the potential relation between body position and sleep characteristics in normal infants. Patients. Two groups of 3-month-old healthy infants were evaluated: 40 infants who usually slept supine, and 40 who usually slept prone. The two groups were matched for gender, gestational age, postnatal age, birth weight, and total recording time. Recording techniques. The 80 infants were studied polygraphically during one night in the pediatric sleep laboratory. They were allowed to fall asleep in their usual sleep position, and every 3 hours were gently turned from prone to supine, or from supine to prone. Results. In each group, 6 infants were excluded from the analysis, because they woke up after having been turned over. In both groups, no significant difference was seen between the prone and the supine body positions for the following variables: number of sleep state changes; number of gross body movements; percent of rapid eye movement sleep; saturation with oxygen, arterial blood levels; number and duration of acid esophageal reflux; rectal temperature; mean respiratory rates; water evaporation rates from the forehead skin; and number or duration of central or of obstructive apneas. In both groups of infants, prone body position was associated with a significant increase in sleep duration (+ 6%) and in non-rapid eye movement sleep (+25%) and a significant decrease in number of arousals (–40%) and in their duration (–43%). Conclusions. No explanation has been found for the sleep-promoting effect of prone body positioning. The finding could be of interest to the study of infants9 sleep quality, as well as to the potential relation between body positions and sudden death during sleep.

Prone or Supine Body Position and Sleep Characteristics in Infants

Because the collection of normative sleep data in the pediatric age group largely depends on technical issues, this article discusses various aspects of sleep recordings in infants and children. Polygraphic monitoring of sleep and waking behavior contributes to a better description of maturational stages in children, from the prenatal period to the end of adolescence. This article reviews the general characteristics of normal children's sleep and the environmental factors that influence these maturational processes. The use of polygraphic recordings to identify neurological deficits and to predict behavioral and neurological outcome in infants and children, however, does not hold great promise. The importance of polysomnographic evaluation is admitted for some major clinical conditions, such as risks for abnormal breathing or narcoleptic attacks.

Normal sleep architecture in infants and children.

Objective. To investigate the effect of prenatal smoking on infant respiratory behavior during sleep.

Methods. A questionnaire concerning family habits and infants' history was completed for 550 healthy infants before a 9-hour night polysomnographic study. Because the data for 41 infants were not available for analysis, 509 subjects were studied: 115 were newborns evaluated within 1 week after birth, and 394 were healthy infants admitted at 11 weeks of life (range 5 to 29 weeks) after various research protocols.

Results. According to the smoking frequency of the mothers during pregnancy, the subjects were defined as "nonsmokers" (no cigarette smoked during pregnancy; n = 400), "light smokers" (1 to 9 cigarettes per day; n = 37), or "smokers" (10 or more cigarettes per day; n = 72). Compared with nonsmokers and light smokers, "smoking" mothers had a significant increase in the number of episodes of uterine bleeding during the pregnancy. Their infants had lower birth weights and more frequent episodes of profuse sweating during sleep. Infants of smokers also had more frequent and longer obstructive sleep apneas than those of the two other groups. For infants of smokers the relative risk for obstructive apneas was 2.76 (95% confidence interval: 1.63 to 4.69; P = .001) The relation between prenatal smoking and postnatal manifestation of obstructive sleep apneas demonstrated a dose-response pattern. Paternal smoking during pregnancy increased the risk of obstructive apneas only in the infants of smoking mothers, but not in those of the two other groups. Maternal smoking after birth did not add significantly to the risk of obstructive apneas. The effect of smoking was seen in older infants, as well as in the newborns not yet exposed to ambient cigarette smoke. A stepwise logistic regression, using obstructive sleep apneas as the dependent variable identified three significant independent variables: smoking during pregnancy ( P = .001), profuse sweating during sleep ( P = .001), and birth weight ( P = .010). No explanation was found for the effect of prenatal smoking on obstructive sleep apneas.

Conclusion. Prenatal smoking by mothers correlated with an increase in frequency and length of obstructive apneas and a decrease in birth weight of their infants. The infants were under greater risk for obstructive apnea if both parents smoked. Explanations for our results are unknown to us, but these findings may be of interest in the study of infant breathing behavior and epidemiological characteristics of sudden infant death syndrome.
