| Summary: | Introduction: Obesity is a factor that is strongly related to the
occurrence of obstructive sleep apnea (OSA) in adults, although this association remains
controversial for children. Objective: The aim of this study was to compare the clinical
and upper airway charactheristics, obtained by questionnaires, physical examination and
laboratory tests, among obese children with and without OSA. Method: This was
aprospective cohort study. 44 obese children (body mass index above the 95th percentile)
were included in the study. Questionnaires, physical examination of the upper airway,
nasofibrolaryngoscopy, polysomnography, and laboratory allergic tests were performed.
Results: There were 22 male patients (50%), and the mean age was 7.6±2.5 years. OSA was
present in 19 (43%) patients. There were no statistically significant differences
between the groups with and without OSA, in relation to clinical or laboratory allergic
parameters. For the upper airway assessments, hypertrophy of the pharyngeal (p=0.001)
and palatine (p=0.049) tonsils were the only parameters associated with OSA, and a
modified Mallampati index of class III/IV also demonstrated a tendency towards being
statistically associated with OSA (p=0.081). Moreover, these findings were confirmed to
be factors associated with OSA in this group of children according to a logistic
regression analysis. Conclusions: The occurrence rate of OSA in this obese pediatric
population was high. Adenotonsillar hypertrophy and a modified Mallampati index of class
III/IV were the factors associated with OSA. |
