Multiple analysis was performed for obesity by adjusting confounding factors such as age and gender in 460 children. Further, to minimize the influence of confounding factors and selective bias, propensity score matching (PSM) was performed in children with OSA. Hematological parameters such as inflammatory and coagulable parameters were compared between the normal weight children with OSA and the obese children with OSA following PSM.Results: OSA (OR = 3.061; P< 0.001; 95% CI, 1.772&ndash; 5.288) represented an independent risk factor for obesity. Besides, the obese children with OSA had higher levels of white blood cell (WBC) (P< 0.001), neutrophil (NEUT) (P< 0.001), neutrophil-lymphocyte ratio (NLR) (P=0.006), fibrinogen (FIB) (P=0.033), while had a lower level of activated partial thromboplastin time (APTT) (P=0.048). No significant differences were observed in other hematological parameters. In linear regression, the results indicated that the levels of WBC (R2 = 0.123, Beta = 0.289, P< 0.001), NEUT (R2 = 0.124, Beta = 0.282, P< 0.001), NLR (R2 = 0.105, Beta = 0.184, P=0.026) and FIB (R2 = 0.086, Beta = 0.246, P=0.003) were positively correlated with BMI, while the level of APTT (R2 = 0.057, Beta = &minus; 0.171, P=0.044) was significantly negatively correlated with BMI.Conclusion: OSA was an independent risk factor contributing to obesity. WBC, NEUT, NLR, FIB and APTT are correlated with obesity in children with OSA (aged from 2 to 14 years). These indicators could be used to estimate the status of inflammation and hypercoagulation in the obese children with OSA.Keywords: obstructive sleep apnea, obesity, propensity score matching, hematological parameter, inflammation, hypercoagulation
