PULMONARY FUNCTION AND SLEEP QUALITY IN ASTHMATIC CHILDREN AND TEENAGERS
Good sleep quality is a determining factor for productivity and dalily activities. The Night awakening is an indicator of worsening asthma control and severity. Thus, the evaluation of sleep disorders in asthmatic patients is important to minimize symptoms and to improve quality of life.
To evaluate the relationship between sleep quality and pulmonary function in asthmatic children and adolescents.
It was a cross-sectional study in 40 children and adolescents diagnosed with moderate and severe asthma. To assess the sleep quality of the volunteers, patients completed the Pittsburgh sleep quality index (PSQI) and their guardians filled out the sleep behaviour questionary (SBQ). The evaluation of the pulmonary function was performed through spirometry.
The sample consisted of 32 (80%) boys and 8 (20%) girls with 9 ± 2 years old. Regarding the PSQI score, 11 (27.5%) had good sleep quality, 4 (10%) had sleep disorder and 25 (62.5%) had poor sleep quality. 4 (10%) who had good sleep quality by the SBQ, only 2 (50%) had the same indication by the PSQI. Twelve (30%) had FEV1 <80% or FEV1 / FVC <70% of the predicted value, with unchanged FVC. Among these, 10 (83.33%) showed poor sleep quality by the SBQ, while 9 (75%) presented poor sleep quality by the PSQI. One (2.5%) participant had FVC <60% with FEV1/FVC> 70% of the predicted value, indicating sleep disturbance by PSQI and poor sleep quality by the SBQ. Fisher exact test showed an association between sleep efficiency and FEF25-75%/FVC (p = 0.001) and FVC (p= 0.05) measurements.
There was no association between PSQI and SBQ overall scores and pulmonary function. All (100%) participants with a seemingly restrictive pattern of disturbance by spirometry (FEF25-75% / FVC> 1.5) had poor sleep quality by SBQ and poor sleep quality or sleep disturbance by PSQI. It is also suggested an association between sleep efficiency and restrictive ventilatory disturbances.
