Pediatric obstructive sleep apnea-related risk factors: A cross-sectional study.

Objectives: This study investigated obstructive sleep apnea (OSA)-related risk factors in children and adolescents.

Materials And Methods: Records of 187 subjects from a private medical clinic were reviewed. Overnight polysomnography recordings and self/parent reports were gathered. Descriptive analysis of sociodemographic, anthropometric, sleep quality and sleep architecture variables and OSA diagnosis were performed. Associations between independent variables and OSA diagnosis were assessed through multivariable logistic regression with robust variance, with a significance level of 5%.  Results: 132 participants were diagnosed with OSA, and 55 were classified as "no OSA" (29.41%). Those overweight or obese were 4.97 times more likely to have OSA than those with normal weight (P =  0.005). Those who reported loud snoring were 2.78 times more likely to have OSA than those who reported mild or moderate snoring intensity. A one-unit increase in arousal index leads to 1.39 increase in the odds ratio (OR) of individuals diagnosed with OSA (P < 0.001), and each one-unit increase in sleep efficiency leads to 1.09 higher odds of not having OSA (P =  0.002).

Conclusions: Significantly increased OSA-related risk factors among overweight/obese children and adolescents and among those who had a parental/self-report of loud snoring were found.
