Association of sleep quality with asthma control and asthma quality of life.

Abstract

Asthma is interconnected with lower health-related quality of life along with lack of sleep. To assess the sleep quality in asthmatic patients. To examine the relationship between sleep quality, asthma control, and sociodemographic characteristics. To assess sleep quality and its association with asthma control and asthma quality. The cross-sectional study included 45 normal control and 45 asthmatic patients. We assessed sleep quality and daytime sleepiness using questionnaires. FEV1 prebronchodilators were recorded by spirometry. Questionnaires on asthma control and asthma quality of life, Gastroesophageal reflux disease impact scale, and sleep apnea scale were filled. Asthmatic subjects were categorized as having either nonsevere asthma or severe asthma. Mann-Whitney <i>U</i> test and Spearman's correlation. The comparison of studied variables Pittsburgh sleep quality index (PSQI) global score, sleep quality, sleep latency, sleep disturbance, sleep medication, and daytime dysfunction between the control and study groups was significant (<i>P</i> value < 0.05). Poor sleep quality was associated with excessive sleepiness (<i>r</i> = 0.31, <i>P</i> < 0.05). The correlation between the asthma control questionnaire (ACQ) with sleep quality and Epworth sleepiness scale (ESS) was significant. Asthma quality of life questionnaire was negatively correlated with sleep quality, ACQ, and ESS. Severely impaired asthma quality of life was correlated with poor sleep quality, poor asthma control, and excessive sleepiness. The association between PSQI and asthma severity was not significant. Poor sleep quality was associated with not well-controlled asthma and severely impaired asthma quality of life.
