| Descripción: | Sleep time may interfere with the ability to perform tasks requiring memory, organization and reasoning. A lack of sleep has been related to cognitive deficits; however, few studies had demonstrated an association between sleep duration and cognitive performance in South American adolescents. Therefore, the aim of the study was to determine whether a correlation between sleep duration and cognitive performance in adolescents exist. Participants from a rural school in Brazil were required to register the time they went to bed to sleep and the time they woke-up the following morning. The Stroop test was used to measure cognitive performance. Independent samples t-tests and a binary logistic regression analysis were computed. Boys went to bed a mean of one-hour later than girls (p < 0.05); however, they woke-up only a mean of 13-min later (p > 0.05). Boys slept 20-min less compared to girls (p < 0.05). Boys read more correctly than girls (p < 0.05); however, no significant gender differences were observed for reading speed and word color performance tests. A significant correlation (r = 0.12, p = 0.01) between sleep duration and cognitive performance on the Stroop test was found. In conclusion, individuals with adequate sleep duration performed better on cognitive tasks than individuals with irregular sleeping habits. |
