Sleep in overweight adolescents: shorter sleep, poorer sleep quality, sleepiness, and sleep-disordered breathing.

OBJECTIVE: To document the sleep of overweight adolescents and to explore the degree to which weight-related sleep pathology might account for diminished psychosocial outcome. METHODS: Sixty children aged 10-16.9 from a weight-management clinic were compared to 22 healthy controls using comprehensive actigraphic, polysomnographic, and parent- and self-report questionnaire assessments. RESULTS: Overweight participants averaged more symptoms of sleep-disordered breathing, later sleep onset, shorter sleep time, and more disrupted sleep than controls. Although the groups did not differ in self-reported sleep habits, multiple concerns were reported by parents of overweight participants, including daytime sleepiness, parasomnias, and inadequate sleep. Group differences in academic grades and depressive symptoms were at least partially accounted for by short sleep and daytime sleepiness. CONCLUSIONS: Excessive weight is associated with an increased risk of sleep problems. There is a need for further research in this area and for clinicians who work with overweight children to evaluate their sleep.

Pediatric sleep disorders.

Pediatric sleep disorders represent a heterogeneous collection of disturbances that require varied intervention strategies. The diagnosis of some sleep disorders (eg, OSAS, narcolepsy, PLMD) require PSG, whereas others can be diagnosed during an office visit with a thorough medical,psychiatric, and sleep history. Sleep disorders place children at risk for school failure, accidents, and social problems, and can place a significant burden on families and the parent-child relationship.

Psychological comorbidity and stress reactivity in children and adolescents with recurrent abdominal pain and anxiety disorders.

OBJECTIVE: To compare clinical symptoms, diagnoses, and physiological measures in children and adolescents with recurrent abdominal pain (RAP) (n = 14), to a group with anxiety disorders (ANX) (n = 14) and a physically and psychiatrically healthy control group (HC) (n = 14). METHOD: The cross-sectional study examined group differences in clinical symptoms of anxiety, somatic complaints, depression, and behavior problems. Physiological measures included heart rate, systolic and diastolic blood pressure, and salivary cortisol in response to the Trier Social Stress Test for Children (TSST-C). Subjects were between the ages of 8 and 16 years. RESULTS: RAP and ANX subjects had comparable scores on most psychological measures, and their scores were higher (n < .05) than those of the HC. The ANX and RAP groups exhibited physiological findings that had more shared similarities than either group with the HC group. Few statistically significant group differences were noted in physiological measures, yet the pattern of findings in blood pressure and cortisol supported the use of the TSST-C and the direction of the findings was consistent with expectations. CONCLUSIONS: Understanding more about comorbidity between RAP and anxiety could have important management implications, with observed congruities between the disorders suggesting treatments already demonstrated to be efficacious for pediatric anxiety and depression might be applied productively to RAP.
