ObjectivePediatric obstructive sleep apnea (OSA) has been shown to lead to the development of chronic cardiometabolic conditions, including obesity and cardiovascular disease. We sought to describe the impact of the success of continuous positive airway pressure (CPAP) and surgery, common treatment options for pediatric OSA, on cardiometabolic conditions.MethodsA retrospective review of patients (≤18 years) diagnosed with OSA based on a polysomnogram at a tertiary care pediatric otolaryngology practice from 2015 to 2019 was conducted. Clinical data, including the systolic blood pressure (SBP) values, body mass index (BMI), overall apnea/hypopnea index (AHI) values, and CPAP compliance, were collected. Linear mixed-effects models were developed to observe the relationship between the clinical measurements of each comorbidity and OSA treatment modalities.Results507 patients were included. BMI and SBP measures were collected for 230 and 277 patients respectively. The difference-in-difference estimate for the SBP z-score percentile after successful treatment was -5.3 ± 2.0 percentile units per 100 days. The difference-in-difference estimate for SBP z-score percentile after successful CPAP treatment was -14.4 ± 4.9 percentile units per 100 days while the estimate after successful surgical treatment was -4.6 ± 2.3 percentile units per 100 days. No significant differences were found between clinical measures for obese patients in any treatment cohort.ConclusionsThe success of OSA management was shown to have a positive impact on SBP in hypertensive patients and no impact on BMI in obese patients. In hypertensive patients, CPAP success tripled improvements in SBP z-score percentile compared to surgical treatment success.
