An overweight school-age child with daytime irritability and sleepiness despite 9-10 hours of sleep overnight is referred for a sleep study after evaluation for possible sleep-disordered breathing. Which action is most appropriate?

• A. Assessment of leptin and ghrelin hormone levels
• B. Taking one or two naps each day to increase sleep
• C. Consultation with a dietician to develop an appropriate diet
• D. Referral to a sleep disorder clinic for a sleep study

Answer: (D)

The main idea is that suspected pediatric sleep-disordered breathing, especially in an overweight child with daytime irritability and sleepiness, requires objective sleep testing to confirm the diagnosis and guide treatment. Polysomnography, done at a sleep disorders clinic, is the gold standard for identifying obstructive sleep apnea and measuring how often breathing is disrupted, oxygen levels drop, and the child arouses during the night. Even with 9–10 hours of sleep, the quality may be poor if breathing is interrupted, which explains daytime symptoms. A sleep study provides concrete data to determine severity and necessary management, such as addressing adenotonsillar hypertrophy, obesity, or considering CPAP if needed. Other options don’t directly establish whether sleep-disordered breathing is present or quantify its severity. Measuring appetite hormones isn’t diagnostic for sleep disorders, napping during the day doesn’t diagnose or resolve the underlying issue and can mask symptoms, and a dietician consult focuses on weight without addressing the sleep problem.
