| pubmed-article:19944037 | pubmed:abstractText | Sleep habits of Portuguese undergraduates are almost unknown, and very few international published articles have addressed whether demographic and academic variables such as residence, university year and academic field, might be associated to the sleep-wake patterns of university students. The aims of the present work were thus to characterize perceived sleep habits, behaviours and problems of Portuguese undergraduates, and to examine them by gender, residence status, university year and academic field. | lld:pubmed |
