COVID-19 lockdown impact on mental health in a large representative sample of Italian adults

Background The potential benefits of the COVID-19 lockdown need to be carefully weighed versus the possible impact on people's daily life and negative mental health effects.We aimed to assess the prevalence of depression, anxiety, insomnia and quality of life before and during the COVID-19 lockdown,identifying subgroups at higher risk of mental distress as a consequence of COVID-19 associated restrictions. Methods Within the Lost in Italy project, a web-based cross-sectional study was conducted on a representative sample of 6003 Italian adults aged 18–74 recruited from April 27 to May 3, 2020, within the nation-wide stay-at-home order. Results The prevalence of depressive symptoms (PHQ-2 ≥ 3) increased from 14.3% before lockdown to 33.2% during lockdown, anxiety symptoms (GAD-2 ≥ 3) from 18.1% to 41.5%, insufficient sleep (≤6 h/day) from 33.7% to 41.1%, unsatisfactory sleep from 17.0% to 38.8% and unsatisfactory quality of life from 13.1% to 42.1%.Overall, 47.7% reported worsened depressive symptoms, 43.6% worsened anxiety symptoms, sleep quantity (31.5%) and quality (35.0%),and 64.1% worsened quality of life.A statistically significant relationship with all mental health outcomes considered was found for women vs. men (multivariate odds ratio,OR between 1.13 and 1.63), for current vs. never smokers (OR between 1.15 and 1.25), and with increasing physical activity (p for trend
