Correlation Between Sleep Quality, Quality of Life, and Pulmonary Function in Post-COVID-19 Individuals

Introdução

Prolonged effects, known as long COVID, have impacted health even after the acute phase. These sequelae include reduced quality of life, sleep disturbances, and alterations in pulmonary function (Stefanou et al., 2022; Ma et al., 2022). Patients often experience chronic fatigue, anxiety, depression, and decreased vitality, which hinder daily activities (Malik et al., 2021). Additionally, disruptions in the sleep-wake cycle exacerbate feelings of tiredness (Gupta et al., 2020), and impaired pulmonary function may worsen these disturbances (Puchner et al., 2021; Lou et al., 2017).

Objetivo

This study aims to explore the ongoing impact of COVID-19 on sleep quality, quality of life, and pulmonary function.

Métodos

This cross-sectional study, approved by the Human Research Ethics Committee (protocol 4.983.173). Participants aged ≥18 years with confirmed COVID-19 via RT-PCR were recruited through social media and flyers. Participants underwent clinical evaluation, spirometry (measuring FVC, FEV1, and FEV1/FVC ratio), actigraphy, and subjective sleep assessment using the PSQI and the ESS. Quality of life was assessed with the SF-36. Data were presented as mean ± standard deviation.

Resultados

Daytime sleepiness (ESS) negatively correlated with physical limitations (r = -0.438) and functional capacity (r = -0.411), indicating that greater daytime sleepiness is linked to more physical limitations and reduced functional capacity. Poor sleep quality (PSQI) also negatively correlated with vitality (r = -0.394), showing worse sleep quality relates to lower energy. PSQI positively correlated with forced vital capacity (FVC) (r = 0.554), suggesting impaired lung function is linked to worse sleep perception. The FEV1/FVC ratio positively correlated with functional capacity (r = 0.402), showing better lung function associates with better physical performance. Physical limitations negatively correlated with total sleep time (r = -0.497), indicating more physical difficulties lead to less sleep. Reduced FVC negatively correlated with vitality (r = -0.467), reflecting lower energy and well-being with decreased lung function.

Conclusões

COVID-19 survivors face significant issues with daytime sleepiness, sleep quality, and pulmonary function. Increased daytime sleepiness and poor sleep quality are associated with physical limitations and lower vitality. Addressing these through targeted rehabilitation may improve overall quality of life.
