Data are standardized linear regression coefficients (β) adjusted for gender, age and race. AHI = apnea hypopnea index. SDB = dummy variable of none (0), primary snoring (snoring + AHI < 2 = 1), mild OSA (2 ≤ AHI < 5 = 2), and moderate OSA (AHI ≥ 5 = 3). OSA = dummy variable of no (AHI < 2 = 0) and yes (AHI ≥ 2 = 1). SpO₂ = dummy variable of normal (SpO₂ > 0.5 = 0) and low (SpO₂ < 0.4 = 1). BMI% = body mass index percentile. BMI% groups = dummy variable of normal weight (BMI% < 85 = 0), overweight (85 ≤ BMI% < 95 = 1), and obese (BMI% ≥ 95 = 2). P values ≤ 0.05 (*), including ≤ 0.01 (**), were considered statically significant, while P values 0.05–0.10 (^T) were considered marginally significant (trend).
