We conducted an anonymous online survey among white-collar workers from various finance, IT and technology companies in Lithuania to define factors associated with worse sleep quality and diminished productivity during a COVID-19 lockdown. Materials and Methods: Employees of selected companies in Lithuania completed an anonymous questionnaire online that included the Pittsburgh Sleep Quality Index (PSQI), The Sleep Locus of Control (SLOC), the Generalized Anxiety Disorder Scale-7 (GAD-7), and the World Health Organization\u2019s Health and Work Performance Questionnaire (WHO-HPQ). Respondents also provided information about their sleep hygiene, physical activity and alcohol use. Results: Data of 114 respondents (56, 49.1% male) were used for analysis. Among them, 49 (43.0%) suffered from poor sleep and 29 (25.4%) had clinically relevant levels of anxiety. However, there were only negligible levels of absenteeism in the sample (a median of zero hours of work lost over the past month). In a stepwise linear regression model (F(5,108) = 11.457, p &lt; 0.001, R2adj = 0.316), high levels of anxiety, daily hours spent using the screen, use of electronic devices in the bedroom, smoking in the evening, and COVID-19-related changes in appetite were associated with worse sleep quality. Absenteeism was associated with physical activity of moderate intensity and decreased self-reported productivity during the pandemic (F(2,111) = 7.570, p = 0.001, R2adj = 0.104). However, there was no strong relationship between sleep-related variables (i.e., sleep hygiene, sleep locus of control, quality of sleep) or levels of anxiety and measures of work productivity. Conclusions: Our findings suggest that while bad sleep hygiene, anxiety, and changes in appetite are associated with worse sleep quality among white-collar workers during the pandemic, work productivity may remain high irrespective of disrupted sleep.<\/jats:p>","DOI":"10.3390\/medicina58070883","type":"journal-article","created":{"date-parts":[[2022,7,3]],"date-time":"2022-07-03T22:50:46Z","timestamp":1656888646000},"page":"883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Quality of Sleep and Work Productivity among White-Collar Workers during the COVID-19 Pandemic"],"prefix":"10.3390","volume":"58","author":[{"given":"Emilijus","family":"\u017dilinskas","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Vilnius University, 03101 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8527-3902","authenticated-orcid":false,"given":"Kristijonas","family":"Puteikis","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Vilnius University, 03101 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u016bta","family":"Mameni\u0161kien\u0117","sequence":"additional","affiliation":[{"name":"Center for Neurology, Vilnius University, 08661 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9","DOI":"10.5114\/biolsport.2020.96857","article-title":"Effects of Home Confinement on Mental Health and Lifestyle Behaviours during the COVID-19 Outbreak: Insights from the ECLB-COVID19 Multicentre Study","volume":"38","author":"Ammar","year":"2021","journal-title":"Biol.
