A factor analysis with varimax rotation was performed with seventeen items of the questionnaire and four factors were extracted: Sleep Disturbance, Sleep Timing, Insufficient Sleep and Dreams\/Nightmares. The questionnaire also included questions on coffee use, cigarette smoking, alcohol intake and physical exercise. The sample consisted of 212 females (M age=20.32 years, SD=1.26) and 128 males (M age=20.19 years, SD=1.23) third year medical students.<\/jats:p><\/jats:sec><jats:sec id=\"S0924933800173511_abst0191\" sec-type=\"results\"><jats:title>Results:<\/jats:title><jats:p>Habitual alcohol intake was reported by 6.5% of the students (males=14.8% vs females=1.4%; p=.000) and regular physical exercise by 37.9% (males=47.7% vs females=32.1%; p=.004); The mean number of coffee cups used per day was 2.16\u00b11.16 (males M=2.18\u00b11.35 vs females M=2.13\u00b11.03; NS) and the mean number of cigarettes smoked per day was 3.69\u00b15.71 (males M=4.41+6.55 vs females M=3.25\u00b15.10; NS). Students who regularly practice physical exercise reported less Sleep Disturbance (p=.004). Habitual alcohol intake was significantly associated with Sleep Timing (p=.051) and Insufficient Sleep (p=.007). Significant correlations were also found between cigarette smoking and Sleep Timing (p=.000), Dreams\/nightmares (p=.023) and Insufficient Sleep (p=.001). Coffee use was correlated only with Sleep Timing (p=.000).<\/jats:p><\/jats:sec><jats:sec id=\"S0924933800173511_abst0291\" sec-type=\"conclusions\"><jats:title>Conclusion:<\/jats:title><jats:p>In this sample of healthy young adults habitual alcohol intake and cigarette smoking was associated with Insufficient Sleep and regular physical exercise was associated with less Sleep Disturbance.<\/jats:p><\/jats:sec>","DOI":"10.1016\/s0924-9338(09)71460-9","type":"journal-article","created":{"date-parts":[[2009,3,14]],"date-time":"2009-03-14T10:37:46Z","timestamp":1237027066000},"source":"Crossref","is-referenced-by-count":1,"title":["Sleep Patterns and Health Behaviours in Medical Students"],"prefix":"10.1017","volume":"24","author":[{"given":"M.","family":"Marques","sequence":"first","affiliation":[]},{"given":"M.J.","family":"Soares","sequence":"additional","affiliation":[]},{"given":"A.","family":"Gomes","sequence":"additional","affiliation":[]},{"given":"B.R.","family":"Maia","sequence":"additional","affiliation":[]},{"given":"A.T.","family":"Pereira","sequence":"additional","affiliation":[]},{"given":"J.","family":"Valente","sequence":"additional","affiliation":[]},{"given":"M.H.","family":"Azevedo","sequence":"additional","affiliation":[]},{"given":"A.","family":"Macedo","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2020,4,16]]},"container-title":["European Psychiatry"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0924933809714609?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0924933809714609?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0924933800173511","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,24]],"date-time":"2024-01-24T08:48:46Z","timestamp":1706086126000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0924933800173511\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,1]]},"references-count":0,"journal-issue":{"issue":"S1","published-print":{"date-parts":[[2009,1]]}},"alternative-id":["S0924933800173511"],"URL":"https:\/\/doi.org\/10.1016\/s0924-9338(09)71460-9","relation":{},"ISSN":["0924-9338","1778-3585"],"issn-type":[{"value":"0924-9338","type":"print"},{"value":"1778-3585","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,1]]},"article-number":"24-E1227"}}
