Demand for multicentric climatic research to investigate the relationship between sleep apnea and other disorders and seasonality

摘要

The merit of the work by Cassol and colleagues1 (see page 1499) is outstanding. The study performed a retrospective clinical analysis of an impressive 7,523 individuals suspected of having some type of sleep disorder over thee span of 10 years. The authors aimed to examine whether a relationship between seasonality and the severity of obstructive sleep apnea (OSA) exists. Through elaborate statistical analysis, results showed an increase in the incidence of more-severe OSA in the winter compared with ftat in the summer. However, the authors acknowledge that the retrospective nature of the study limits the ability of the main question to be adequately addressed.
