Jansen J, Shulman R, Ward TM, et al. - In youth with functional gastrointestinal disorders (FGIDs), researchers sought to better describe sleep problems and to evaluate relationships with demographic features and gastrointestinal (GI) symptoms. For this study, 67 children with FGIDs (pediatric Rome IV criteria) and 59 parents responded to questionnaires evaluating sleep problems, and children filled out a 2-week pain/stooling diary. According to findings, sleep problems in children with FGIDs are common and associated with higher day-to-day abdominal pain severity and pain interference. For sleep disturbances, 61% were above clinical cutoff with significantly higher bedtime resistance, sleep onset delay, sleep duration, and daytime sleepiness vs the comparison group. Higher mean abdominal pain severity and pain interference was reported by children above clinical cutoff. Black/African American patients were more likely to be above clinical cutoff and specified more frequent night wakening and symptoms of sleep-disordered breathing, but reduced maximum and overall mean abdominal pain severity vs White patients.
