An Analysis of Laryngomalacia and Its Interplay With Obesity and Obstructive Sleep Apnea in Pediatric Inpatients

Objective This study aimed to investigate the potential relationship between laryngomalacia and obesity as well as explore the interplay between laryngomalacia and obstructive sleep apnea using the Kids' Inpatient Database (KID) for the year 2016. Methods The Healthcare Cost and Utilization Project (HCUP) KID for 2016 provided a dataset for analysis. Patient demographics, diagnoses, and hospital characteristics were considered. Patients less than three years old were included due to the high prevalence of laryngomalacia in this age group. Results Among 4,512,196 neonatal admissions, 1,341 obesity cases and 11,642 laryngomalacia cases were analyzed. The frequency of laryngomalacia in patients with obesity was 578.1% higher than in the general population. Patients with obstructive sleep apnea (OSA) exhibited a 5,243.2% increase in laryngomalacia frequency compared to the overall population. Combining obesity and laryngomalacia resulted in a 6,738.5% increase in OSA frequency. Conclusions This study identified a significant correlation between obesity and increased laryngomalacia risk. The findings have important clinical implications for pediatric care, emphasizing the need to prevent childhood obesity to reduce laryngomalacia risk. Additionally, understanding these risk factors enables better risk stratification for laryngomalacia and potential OSA development.
