OBJECTIVE: Obstructive sleep apnea causes a marked decrease in lung volume and increases lung elasticity in obese adults. However, pulmonary and respiratory muscle function of obese children with obstructive sleep apnea who are more prone to develop airway obstruction than adults is less understood. This study aimed to determine the effects of obstructive sleep apnea on pulmonary and respiratory muscle function in obese children and adolescents compared to those without obstructive sleep apnea.

MATERIAL AND METHODS:This cross-sectional study enrolled 12 obese children and adolescents with a known polysomnographic diagnosis of obstructive sleep apnea and 12 controls that were matched for age, gender, and body mass index. Pulmonary function, maximal inspiratory pressure, maximum voluntary ventilation, and anthropometric variables were measured.

RESULTS Obese children and adolescents with obstructive sleep apnea exhibited significantly lower maximal mid-expiratory flow and displayed a forced expiratory flow at 50% and 75% of vital capacity (all P < .05) compared to the control group. However, there were no changes in other pulmonary function variables (all P > .05). Their maximal inspiratory pressure and maximum voluntary ventilation were lower than those of the controls, but this was not statistically significant (all P > .05).

CONCLUSION: Obstructive sleep apnea did not change pulmonary and respiratory muscle function in obese children and adolescents. The special assessment should be warranted to identify a reduction in maximal mid-expiratory flow and forced expiratory flow at 50% and 75% of vital capacity observed in this population.
