AIM: Investigate the relationship between body mass index (BMI), OSA on PF in children.
MATERIALS & METHOD: Seventy-four children were recruited. Mixed obstructive apnoea-hypopnea index (MOAHI), BMI, oxygen saturation (SpO2 ), forced expiratory volume one second (FEV1 ), forced vital capacity (FVC) and fractionated exhaled nitric oxide (FeNO) were measured.
RESULTS: Twenty-four and thirty children had mild OSA and moderate-to-severe OSA respectively. BMI correlated negatively with SpO2 nadir (r = -.363, p = .001). FVC, FEV1 and nadir SpO2 values decreased with OSA severity (p
