Background: Several studies have shown that surviving patients of Covid-19 have psychological sequelae, such as fear and sleep disorders.

Objective: To investigate differences in the prevalence of sleep disorders between COVID-19 survivors, according to the intensity of fear of disease.

Method: 361 COVID-19 survivors participated, whose was evaluated with an interview on sleep disturbances and COVID fear scale. Patients were grouped according with the intensity of fear:G1(none,0-7points,n=192),G2(mild,8-16 points,n=127),G3(moderate severe,<17,n=42). Statistical analysis was performed with Mann-Whitney U test and chi square to determine difference in groups, SPSS V25 was used.

Results: Sociodemographic variables(p>0.05),G1:57.08±15.34 years,70.3% men,G2:56.52±14.80 years,61.4% men,G3:51.74±16.62,59.5% women.

There were statistically significant differences(p<0.05)between groups(G1,G2,G3) in sleep apnea(0.0%,0.8%;2.4%);onset insomnia(24.5%,39.4%;40.5%);intermediate insomnia(25.5%,37.0%;47.6%)and final insomnia(18.2%,29.9%;40.5%). There were no statistically significant differences(p>0.05): regular sleep schedule(17.2%,19.7%,28.6%);less than seven hours of night sleep(34.4%,35.4%,33.3%);poor sleep quality(0.5%,3.1%,4.8%);consumption of drugs to sleep with or without a prescription(10.9%,16.7%, 14.3%);bruxism(10.9%,22.8%,21.4%);sleep paralysis(8.3%,9.4%,23.8%);limb shaking(17.7%,21.3%,26.2%)and abnormal movement(15.1%,17.3%,26.2%).

Conclusions: There is a difference in the prevalence of sleep disorders between COVID-19 survivors, particularly in apnea and insomnia where was statistically significant. However, clinical differences were observed in all indicators in patients who presented fear at some level.
