RESUMO:

The delayed sleep phase, characterized by later sleeping and waking hours, seen in adolescence may persist after the youths' entry into university. In this context, many students use stimulants to minimize the effects of daytime sleepiness generated by chronic partial sleep deprivation on week schooling. This behavior can modify the habits and quality of sleep and thus, cause damage in the attention of those of the morning shift. Knowing that attention is a basic process capable of interfering in cognitive processes and that knowledge acts in decision making, we investigate the relationship between the level of knowledge about sleep and habits and the quality of sleep, and the components of attention young people from an RN public university. The 35 participants (19.8 ± 1.9 years old - 27 women and 8 men) answered the questionnaires: Health and Sleep, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Morningness-Eveningness Questionnaire & Östberg; filled out the Sleep Diary and used an actiwatch for 10 days, and performed a Continuous Execution Task. Overall, G2 reported better sleep habits when compared to G1, such as: lower cell phone use and higher frequency of spontaneously arouse on school days, lower caffeine intake before sleep and less irregularity in total sleep time. Regardless of the group, some sleep habits differed between school days and free days. The bed, sleep, wake-up and get up times occurred earlier in school days (Anova, p <0.05) and the total time in bed and sleep duration were shorter on school days (Anova, p <0.05). However, the number of awakenings after sleep onset was greater on the days off (Anova, p <0.05). The quality of sleep did not differ according to the knowledge about sleep whereas daytime sleepiness scores were negatively correlated with the number of correct sleep alternatives (r = -0.35, p <0.05). Daytime sleepiness was reported more frequently by G1 (X2, p <0.05) who tended to have higher means of sleepiness scores (Mann-Whitney, p <0.05). At wake-up time, the sleepiness differed only between class and free days (Anova, p <0.05). The performance in the task that evaluates the four components of attention differed from that expected, since there was no relationship between performance and sleep knowledge. Most indicators and components of attention did not differ. There was only a tendency for G2 to present a reduction in the percentage of correct responses throughout the task (Anova, p = 0.09), suggesting a trend towards less sustained attention. Therefore, it is suggested that knowledge about sleep is related to the practice of better sleep habits and lower diurnal sleepiness. However, no relationship was observed regarding knowledge, sleep quality and performance in the attention task. Therefore, it is necessary to expand the sample to clarify the relationship between the level of knowledge about sleep and sleep habits and quality, and the components of attention of college students.
