CORRELATION BETWEEN OBJECTIVE AND SUBJECTIVE MEASURES OF THE SLEEP PARAMETERS IN POST-COVID-19 PATIENTS.

Introdução

Introduction: SARS-CoV2 infection has a serious pandemic character and high
potential for transmission around the world. This disease has been generating
repercussions in affected patients even in the post-COVID phase. Changes in the sleep
parameters are highly prevalent and can affect the functional capacity and quality of life
of these patients. Thus, it is important to evaluate and monitor sleep-related variables in
the post-covid period.

Objetivo

Objective: To assess the correlation between objective and
subjective measures of sleep parameters in post-COVID-19 patients.

Métodos

Methodology:
This is a cross-sectional study and the objective assessments of sleep included sleep
efficiency (SE), total sleep time (TST), Wake episodes per night (WE) and sleep latency
(SL), obtained by the Actigraph (ActTrust, ® Condor) used for 7 days. The subjective
sleep quality (SQ) was assessed using the Pittsburgh sleep quality questionnaire (PSQI)
and the excessive daytime sleepiness (EDS) using the Epworth sleepiness scale (ESS).
Data are shown as mean, standard deviation and percentage. The Spearman correlation
test was used to evaluate the correlation between the variables, A statistical significance
level of p ≤ 0.05 was considered.

Resultados

Results: Fifteen patients were evaluated, aged
44.8±14.4 years, and the prevalence of females (83.3%). Regarding to the PSQI results,
poor sleep quality was observed in the entire sample (100%). However, the subjects did
not show EDS. Correlating objective and subjective measures of sleep parameters, a
positive correlation was observed between the PSQI score and TST (p=0.018; r=0.60).
There was no correlation between PSQI score and SL (p= 0.37; r= 0.17), SE (p= 0.67;
r= - 0.11) and, WE (p= 0.92; r=0.27). There was also no correlation between ESS score
and TTS (p= 0.77; r= 0.08), LS (p= 0.28; r= 0.29), ES (p= 0.81; r = - 0.06) and the ND
(p= 0.30; r= 0.28).

Conclusões

Conclusion: In accord to the results, a positive correlation was
observed between sleep quality (PSQI score) and total sleep time. However, there was
no correlation between the PSQI and ESS scores and the other objective sleep
parameters.
