At the time of the survey, most participants reported good sleep quality (n = 1026; 56.2%), with 39.5% (n = 721) reporting poor sleep quality. However, 53.7% of participants experienced a change in their sleep habits since the beginning of lockdown, more frequently represented by a decrease in the amount and/or regularity of sleep (OR 3.68; 95% CI 2.32–5.82; p < 0.001).
