The COVID-19 lockdown induced changes in sleep habits among Croatian general population

The aim of the study was to investigate the effects of lockdown on sleep habits during the COVID-19 epidemic in the Croatian general population and to explore potential influence factors. Using an online cross-sectional survey, 1173 subjects from the general population (male=288, female=809) completed a self-reported questionnaire assessing demographic data, sleep habits and mood changes prior to and during lockdown. Results indicated a postponed bedtime (from 23:11±1:07 to 23:49±1:32 h, p<.001) and wake-time (from 6:51±1:09 to 7:49±1:40 h, p<.001) during lockdown. Sleep latency increased from 10 (5-20) to 15 (10-30) minutes during lockdown (p<.001). Bedtime and wake-time shift was more pronounced in females than in male subjects. Respondents under 30 years of age had the most pronounced delay in bedtime and wake-time. Also, they reported insomnia for the first time during lockdown more frequently and had less frequent awakenings (p<.001), less common problems falling asleep (p<.001), less frequently reported feeling calm (p<.001) and rested (p<.001), but expressed more frequent reports of sadness (p<.001) and fear (p=0.028) during lockdown than others. In conclusion, lockdown measures promoted a shift in sleep time along with prolonged sleep latency, increased first time reports of insomnia especially in respondents younger than 30 years of age, combined with mood changes. Younger age and less common problems with night-time awakenings and falling asleep were associated with increased odds for developing insomnia during the lockdown implemented during the COVID-19 pandemic.
