[Childhood obesity and sleep breathing disorders].

Obstructive sleep apnea (OSA) is common in childhood obesity and is mainly due to adenoid and tonsillar hypertrophy. Surgical management with adenotonsillectomy will be the first line of treatment for obese children with OSA in addition to weight loss. In addition, recent data suggested that sleep deprivation in infancy may be associated with obesity later in life, probably due to hypothalamic dysregulation with modifications in hormones involved in food intake regulation. It confirms that it is crucial to evaluate sleep for all obese children with questionnaire in order to improve their management and their quality of life.
