| Resumo: | Adolescence is a period of many changes regarding biological, psychological and social factors. Among them, one occurs in sleep patterns, marked by a delay in sleep phase and affected by biological development and environmental cues. Studies show that on weekdays, these individuals’ wakeup earlier due to social demands, like school schedules, thus reducing sleep duration. On the other hand, on weekends they show a delay on bedtimes and wakeup times, increasing sleep duration. Therefore, sleep deprivation is evident, and adolescents tends to make up for sleep loss on weekends. However, this compensation may not have the desired effect, as sleep deprivation during the week can cause impairments in cognitive processes, especially attention span. So, this study aims to evaluate relationships between irregularity in sleep schedules and time in bed among week and weekend, and attention components in high school students of the morning shift, as well as the relationship of these variables with sleepiness upon waking and chronotype for a better understanding of this process. Data were collected from 149 adolescents enrolled in the morning shift in private high schools. They answered questionnaires about sleep habits, completed a sleep diary for 10 days and took a Continuous Performance Task (CPT), to evaluate attention components. We found correlations between chronotype and ‘social lag’, and bedtime and wakeup times irregularities. We suppose that later chronotypes have greater bedtime, wakeup times and mid-sleep times irregularity (‘social lag’), presenting a mismatch in sleep phase between weekdays and weekends. In addition, we found correlations between bedtime irregularity and some CPT variables like regression indices of correct answers and of reaction times, both indicators of sustained attention; as well as between wakeup times irregularity and reaction times in tonic alertness. Thus, greater bedtime irregularity meant low sustained attention efficiency. However, greater wakeup times irregularities were associated with shorter reaction times in tonic alertness. This contradiction may have occurred due to commission errors. Like previous studies, later chronotypes were related to greater irregularity in sleep schedules. However, irregularities in time in bed and sleep schedules were poorly related to tonic alertness and sustained attention only. We suggest a larger sample to better study these relationships. |
