    Abstract

    BACKGROUND

    Sitting time, screen time and low physical activity (PA) levels have been associated with several diseases and all-cause mortality. PA is related to better sleep quality and absence of daytime sleepiness, along with lower risks of obstructive syndrome apnea (OSA). However, studies on the relationship between sitting time, screen time and OSA are scarce in the literature.

    OBJECTIVE

    To analyze associations between PA levels, sitting time, screen time and OSA among adults with suspected sleep disorder. 

    DESIGN AND SETTING

    Cross-sectional study conducted at Hospital Israelita Albert Einstein. 

    METHODS

    Data were collected from 369 adults with suspected sleep disorders who visited the hospital’s neurophysiology clinic between August 2015 and January 2017. 

    RESULTS

    Correlations between hypopnea and PA indicators were demonstrated for total sitting time (0.123; P = 0.019) and total screen time (0.108; P = 0.038). There was also a correlation between latency for rapid-eye-movement sleep (REM_LAT) and total sitting time (0.103; P = 0.047) and a negative correlation between mean oxyhemoglobin saturation (SaO_Avg) and total PA time (-0.103; P = 0.048). There were no associations between PA parameters and apnea-hypopnea index. After adjusting for confounding factors (body mass index, age and gender), sitting time and screen time were not associated with OSA. 

    CONCLUSION

    After adjusting for anthropometric and clinical factors, excessive sitting time or screen time was not associated with OSA in adults suspected of sleep disorders. Age, gender, hypertension, body mass index and waist circumference were associated with OSA.
