Treating obstructive sleep apnea in children is found to be associated with blood pressure decreases. However, exactly how adenotonsillectomy (T&A) affects blood pressure in obese and nonobese children remains unclear. This study assesses how obesity affects blood pressure in children with sleep apnea after T&A. Study Design. Case series with chart review. Setting. A tertiary referral center. Subjects and Methods. From 2010 to 2012, a total of 78 children were included. Based on propensity score methods (age, sex, and preoperative apnea-hypopnea index matched), children were assigned to either the obese group (n = 39) or the nonobese group (n = 39). All children received adenotonsillectomy. We recorded clinical symptoms, preoperative overnight polysomnography (PSG), and subsequent PSG within 3 months after T&A. We measured blood pressure 3 times before PSG (nocturnal blood pressure) and after PSG (morning blood pressure) in a sleep laboratory. Results. Following surgery, the nonobese group had a significantly decreased nocturnal diastolic blood pressure (DBP) index (-12.0 to 218.8, P = .018), morning systolic blood pressure (SBP; 111.1 to 105.8 mm Hg, P = .014), SBP index (-5.4 to 210.9, P = .008), and DBP (-12.0 to 218.7, P = .023). Nevertheless, all blood pressure parameters in the obese group were not significantly changed postoperatively. The nonobese group improved more than obese group in nocturnal and morning DBP and DBP index by 2-way analysis of variance. Conclusion. Among the children receiving T&A as treatment for OSA, nonobese children improved more than obese children did in terms of blood pressure, allowing us to infer that obese children with OSA may benefit less from T&A in cardiovascular morbidities. ? 2015 American Academy of Otolaryngology-Head and Neck Surgery Foundation.[SDGs]SDG3adenoid hypertrophy; adenoidectomy; adenotonsillar hypertrophy; Article; blood pressure measurement; case study; child; childhood obesity; controlled study; diastolic blood pressure; female; human; major clinical study; male; medical record review; polysomnography; postoperative period; preoperative period; school child; sleep disordered breathing; systolic blood pressure; tertiary care center; tonsillectomy; adenoid; blood pressure; obesity; pathophysiology; physiology; propensity score; Sleep Apnea, Obstructive; Adenoids; Blood Pressure; Child; Female; Humans; Male; Obesity; Polysomnography; Postoperative Period; Propensity Score; Sleep Apnea, Obstructive; Tonsillectomyjournal article10.1177/0194599815573927259539122-s2.0-84930743064
