The shifting relationship between weight and pediatric obstructive sleep apnea: A historical review

Objectives

For more than a century, pediatric obstructive sleep apnea (OSA) was associated with failure to thrive. However, that association has faded over the last few decades. A 21st century child with OSA is much more likely to be overweight than underweight. This raises the question: Has pediatric OSA changed over time, or has the rise of childhood obesity in the United States created a new, separate disease? This literature review explores the historical shift in the relationship between weight and OSA, and the associated changes in treatment.

Results

We demonstrate a clear transition in the prevalence of failure to thrive and obesity in the OSA literature in the mid‐2000s. What is less clear is whether these two clinical phenotypes should be considered two distinct diseases, or whether subtle differences in one set of pathophysiologic pathways—adenotonsillar hypertrophy, altered inflammation, and increased energy expenditure—can lead to divergent metabolic outcomes. More research is needed to fully elucidate the pathophysiology of OSA in children with obesity.

Conclusions

We may need new and different treatments for obesity‐associated OSA as adenotonsillectomy—which is effective at reversing failure to thrive in OSA—is not as effective at treating OSA in children with obesity. One option is drug‐induced sleep endoscopy, which could personalize and improve surgical treatment of OSA. There is some evidence that therapies used for OSA in adults (e.g., weight loss and positive airway pressure) are also helpful for overweight/obese children with OSA. Laryngoscope, 2018
