While sleep quality has been frequently investigated, results have not always been consistent. In China, Wang and colleagues found that 75% of 2289 individuals isolated at home rated their sleep as very good [11], but a smaller prospective study found that 37% of a sample of young Chinese adults reported a worsening of their sleep quality during the pandemic [12]. Studies conducted in other countries have demonstrated that lockdown could either lead to an increase in the amount of time spent in bed [13,14], with good sleep efficiency [13] or associated with sleep disorders [15,16] and disruption of one’s habitual circadian rhythm [14]. This topic has also been investigated in Europe, where 55% of Spanish adults changed their sleep pattern after the beginning of the lockdown [17], and individuals who were physically active prior to the SARS-CoV-2 spread reported major sleep problems [18]. In Italy, cross-sectional investigations have suggested that while the number of hours spent in bed might have increased during lockdown [2], many individuals reported insomnia (43%) [19] and poor sleep quality (57%) [9]. Similar percentages of sleep deterioration (48%) were also shown in the UK [20], and a longitudinal study conducted in Italy confirmed the detrimental effects of the 40-day lockdown on all the parameters of the Sleep Quality Index [21], except for sleep duration [22]. Our cohort seems to confirm that sleep quality deteriorated during lockdown, as among those individuals who experienced a change in their sleep quality, 85.8% defined their sleep as poor. This proportion of individuals accounted for 46% of the entire cohort investigated, which is strikingly similar to the proportion of those who reported a worsening of sleep quality in the above-mentioned Italian studies.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"69","span":{"begin":1037,"end":1047},"obj":"Species"},{"id":"70","span":{"begin":708,"end":729},"obj":"Disease"},{"id":"71","span":{"begin":754,"end":769},"obj":"Disease"},{"id":"72","span":{"begin":1259,"end":1267},"obj":"Disease"},{"id":"73","span":{"begin":1336,"end":1355},"obj":"Disease"}],"attributes":[{"id":"A69","pred":"tao:has_database_id","subj":"69","obj":"Tax:2697049"},{"id":"A70","pred":"tao:has_database_id","subj":"70","obj":"MESH:D012893"},{"id":"A71","pred":"tao:has_database_id","subj":"71","obj":"MESH:D012893"},{"id":"A72","pred":"tao:has_database_id","subj":"72","obj":"MESH:D007319"},{"id":"A73","pred":"tao:has_database_id","subj":"73","obj":"MESH:D007319"},{"subj":"69","pred":"source","obj":"LitCovid-PubTator"},{"subj":"70","pred":"source","obj":"LitCovid-PubTator"},{"subj":"71","pred":"source","obj":"LitCovid-PubTator"},{"subj":"72","pred":"source","obj":"LitCovid-PubTator"},{"subj":"73","pred":"source","obj":"LitCovid-PubTator"}],"namespaces":[{"prefix":"Tax","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"},{"prefix":"MESH","uri":"https://id.nlm.nih.gov/mesh/"},{"prefix":"Gene","uri":"https://www.ncbi.nlm.nih.gov/gene/"},{"prefix":"CVCL","uri":"https://web.expasy.org/cellosaurus/CVCL_"}]},{"project":"LitCovid-PD-HP","denotations":[{"id":"T2","span":{"begin":1259,"end":1267},"obj":"Phenotype"}],"attributes":[{"id":"A2","pred":"hp_id","subj":"T2","obj":"http://purl.obolibrary.org/obo/HP_0100785"},{"subj":"T2","pred":"source","obj":"LitCovid-PD-HP"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T78","span":{"begin":0,"end":189},"obj":"Sentence"},{"id":"T79","span":{"begin":190,"end":284},"obj":"Sentence"},{"id":"T80","span":{"begin":285,"end":556},"obj":"Sentence"},{"id":"T81","span":{"begin":557,"end":833},"obj":"Sentence"},{"id":"T82","span":{"begin":834,"end":1090},"obj":"Sentence"},{"id":"T83","span":{"begin":1091,"end":1312},"obj":"Sentence"},{"id":"T84","span":{"begin":1313,"end":1581},"obj":"Sentence"},{"id":"T85","span":{"begin":1582,"end":1769},"obj":"Sentence"},{"id":"T86","span":{"begin":1770,"end":1990},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T78","pred":"source","obj":"LitCovid-sentences"},{"subj":"T79","pred":"source","obj":"LitCovid-sentences"},{"subj":"T80","pred":"source","obj":"LitCovid-sentences"},{"subj":"T81","pred":"source","obj":"LitCovid-sentences"},{"subj":"T82","pred":"source","obj":"LitCovid-sentences"},{"subj":"T83","pred":"source","obj":"LitCovid-sentences"},{"subj":"T84","pred":"source","obj":"LitCovid-sentences"},{"subj":"T85","pred":"source","obj":"LitCovid-sentences"},{"subj":"T86","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PubTator","color":"#a693ec","default":true},{"id":"LitCovid-PD-HP","color":"#9aec93"},{"id":"LitCovid-sentences","color":"#ec93b4"}]}]}}
