Abstract
Despite the significant prevalence of obstructive sleep apnea syndrome (OSAS) in children, the diagnosis and treatment of this condition is still challenging due to the difficulties inherent to objectively assessing the disease's severity. ObjectiveTo verify whether the Portuguese version of the Obstructive Sleep Apnea-18 (OSA-18) survey is as valid as its original version in English. MethodProspective study. The OSA-18 was translated into Portuguese, culturally adapted, and tested in the Portuguese population. The caregivers of 51 children (aged from 2 to 12 years) diagnosed with OSAS answered the OSA-18-pv survey. Statistical analysis was used to assess the psychometric properties of the survey. ResultsReliability analysis yielded a Cronbach's alpha of 0.821, confirming the survey's consistency. Converging validity was assessed using Pearson's correlation coefficient, which revealed a statistically significant correlation between individual data and total results. The survey can be easily and quickly answered (7.26 min). The outcomes of the OSA-18-pv showed that quality of life was poor in 14 children with OSAS (28%), moderate in 22 (43%), and high in 15 (29%). Conclusionthe OSA-18-pv is a valid tool and can be used to assess the impact on the quality of life of Portuguese children with OSAS.
Highlights
Obstructive sleep apnea syndrome (OSAS) is a respiratory disorder characterized by prolonged partial obstruction and/or intermittent complete obstruction of the upper airways and interruption of normal ventilation during sleep[1].Pediatric OSAS became an important topic because of its high prevalence, and due to its associations with different comorbidities, some of which bearing possible implications to the affected subject’s adult life
The outcomes of the Obstructive Sleep Apnea-18 (OSA-18)-pv showed that quality of life was poor in 14 children with OSAS (28%), moderate in 22 (43%), and high in 15 (29%)
This study showed that the OSA-18-pv is an adequate translation
Summary
Pediatric OSAS became an important topic because of its high prevalence, and due to its associations with different comorbidities, some of which bearing possible implications to the affected subject’s adult life. Its prevalence is yet unknown, pediatric OSAS has been estimated to affect 1%-2 % of children, with cases peaking between the ages of two and eight years, at a time in which the Waldeyer’s ring is enlarged[2]. Surgery has been proven effective in controlling neurocognitive sequelae of OSAS, such as poor school performance and attention deficit and hyperactivity disorder, in improving left and right ventricular ejection fraction, and in decreasing the levels of biomarkers of inflammation[4]. Polysomnography (PSG) is currently the gold standard test for the diagnosis of OSAS in children.
