“…Since the study population was young adults attending a university, effects of age on sleep disturbances could not be found. Like in many studies showing that sleep disturbances are found more frequently among women than men (7)(8)(9)(10)(11)(12), it was found in this study that the female students slept slightly shorter and reported more sleep disturbances than their male counterparts.…”

Objective of this study was to look into sleep patterns of university students in association with their lifestyle, specifically to examine mean sleep duration, prevalence of sleep disturbances and their correlates. This study also aimed to examine a possible association of sleep patterns of young adults with new media like computers and videos, which were supposed to have a great influence on their lifestyle. Self-reported sleep data were derived from questionnaires administered to a total of 1,414 students of one university located in Chullabuk-do, Korea. Statistical methods such as t-test, analyses of variance, chi-square test and multivariate logistic regression were used for analysis. The mean sleep duration of the respondents was 6.7+/-1.3 hr. Of the respondents, 30.2% reported having insufficient sleep. About one third of them pointed to visual media including computers as the primary reason. The proportion of those having some types of sleep disturbances was 36.2%. The risk of subjective sleep disturbances was significantly lower among those perceiving themselves healthy than among those perceiving themselves unhealthy (OR=0.44; 95% CI: 0.34-0.57).

“…He confirmed that stress, and in particular stress originating from the home, is the main determinant of the presence of insomnia. The greatest prevalence of insomnia in the group of previously married individuals was verified in other populational studies 10,12,14,22 . Bixler 27 observed in Los Angeles a strong association between loneliness and insomnia, which is perhaps a common aspect in previously married individuals.…”

“…Among women and widowers or separated people, the prevalence of BDZ use was significantly higher. In Switzerland 29 , 7% of use of hypnotic drugs was found without a medical prescription in groups of chronic insomniac people with ages from 20 to 21 years old and 12% in the group from 27 to 28 years of age. A Brazilian general population survey 3 detected 14.6% of hypnotic drug use in the last month, twice as much as in this paper.…”
