CORRELATION BETWEEN SLEEP PARAMETERS AND PHYSICAL ACTIVITY LEVELS IN POST-COVID-19 PATIENTS: CROSS-SECTIONAL STUDY

Introdução

SARS-CoV2 has had repercussions on the health of affected patients, even after hospital discharge, potentially causing changes in sleep parameters and impairing sleep quality. However, physical activity can influence sleep health by regulating the sleep-wake cycle through modulation of the neurohormonal system and reduction of inflammatory responses.

Objetivo

To correlate sleep parameters with physical activity levels in post-COVID-19 patients.

Métodos

A cross-sectional study, registered under number 5,536,992, conducted between November 2022 and June 2023 at the Cardiopulmonary Rehabilitation Laboratory of the Department of Physical Therapy at the Federal University of Pernambuco. Sleep parameters were assessed using actigraphy, including wake-up time, time in bed, total sleep time, and number of awakenings. Additionally, sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI), and physical activity level was assessed using the International Physical Activity Questionnaire (IPAQ). Results are presented as mean and standard deviation. Pearson and Spearman correlation tests were used.

Resultados

Forty-eight patients were selected, with an average age of 41.2 ± 14.4 years and a prevalence of females (64.6%). Negative correlations were observed between moderate activity frequency and wake-up time (p=0.037; r=-0.302), time in bed (p=0.030; r=-0.314), and total sleep time (p=0.036; r=-0.303). Negative correlations were also found between moderate activity duration and time in bed (p=0.006; r=-0.391) and between moderate activity duration and total sleep time (p=0.027; r=-0.319). Positive correlations were observed between vigorous activity frequency and the number of awakenings (p=0.032; r=0.310), and between walking frequency and duration and sleep quality according to the PSQI score (p=0.002; r=0.438) (p=0.002; r=0.41), respectively.

Conclusões

The study found negative correlations between moderate physical activity frequency and wake-up time, time in bed, and total sleep time, as well as between moderate activity duration and total sleep time. Positive correlations were found between vigorous activity frequency and the number of night awakenings, and between walking frequency and duration and sleep quality. Therefore, implementing regular physical activity protocols is important for treating sleep disorders in post COVID-19 patients and preventing complications related to poor sleep quality
