SUMMARY:

The objective of this study was to evaluate the relation between use of electronic media and degree of urbanization of living areas with the sleep-wake cycle and attention components in adolescents. 214 adolescents between 12 and 18 years-old, of both sexes, participated in the study, being 111 from the suburban area and 103 from the urban area, enrolled in the 8th and 9th years of Elementary School II in morning shift of the Rio Grande do Norte/Brazil public school system. The sleep-wake cycle was assessed by the questionnaires “Health and Sleep”, “Pittsburgh Sleep Quality Index”, “Morningness-Eveningness questionnaire” and “Pediatric Daytime Sleepiness Scale”; in addition to Sleep Diaries and actigraphy for 10 days. While attention, was assessed by the Continuous Performance Task. Most adolescents that have electronic devices in the bedroom, being cell phones the majority, have the habit of sending messages before going to sleep, listening to music and using it when waking up at night. Most people who share a bedroom with these adolescentes also report the use of cell phones in the bedroom. In the urban area, adolescents report: having greater proportion of TV in the bedroom and the habit of watching it before bed, having internet at home and on their cell phones and having greater proportion of internet access at home, but less internet access on their cell phones, than the suburban area. In addition, in the uran area, they have greater irregularity in get up time and more reports, during weekdays, of waking up only when someone calls them, in relation to those in the suburban area, who mostly wake up with alarm clock aid. There was also a greater tendency to eveningness and higher levels of daytime sleepiness in the urban area. Regardless of the area, adolescents presented poor sleep quality and claimed the use of an electronic device before going to sleep, at least one day per week, with greater frequency of use on weekdays. Regarding the components of attention, there was a higher percentage of correct responses in all components, greater general stability during the task, lower percentage of omissions in tonic alertness and selective attention and a tendency to have lower percentage of omissions in phasic alertness, in the urban area. As for the relation between use of eletronic media and degree of urbanization with sleep variables, the general multivariate linear model did not show associations between use of media and sleep variables. On the other hand, the urban area was associated with lower sleep efficiency on weekdays (β = - 0.64; p <0.01) and weekend, (β = - 0.70; p <0.01), lower sleep latency on weekend (β = - 0.31; p <0.01), greater number of nighttime awakenings on weekdays (β = - 0.69; p = 0.00) and weekend (β = - 0.64; p <0.01), greater irregularity in bedtime (β = 0.38; p <0.01) and get up time (β = 0.66; p <0.01) and had higher percentage of correct responses in selective attention (β = 0.26; p <0.01). In addition, the model pointed out that girls have higher levels of daytime sleepiness (β = - 0.18; p = 0.04), lower sleep efficiency on weekdays (β = 0.17; p = 0.02), and fewer nighttime awakenings on weekend (β = 0.22; p <0.01) when compared to the boys. Thus, in both áreas, adolescents use eletronic media and have bad sleep habits. The urban area was associated with greater irregular sleep hours, worst sleep quality, greater daytime sleepiness, tendency to eveningness and better attentional performance.
