“…); a similar increasing trend in computer use was identified in other countries, such as Germany, Brazil, the US, and Australia (25,27,31,43). Although a study of US children aged 9-13 suggests that a decrease in time spent watching television is replaced by time spent using a computer (29), in other longitudinal or secular trend studies (27,31,46,47), and also in the present study, time spent using a computer is increasing faster compared with the decline in that spent watching television. In sum, we note an increase in total screen time among Czech schoolchildren between 2006 and 2014.…”

SUMMARYObjective: Screen-based behaviours such as watching television or computer use are among the most prevalent sedentary behaviours adolescents spend time on. There is a lack of recent estimates on prevalence and changes in the amount of time spent on screen-based behaviour across Central and Eastern Europe. The main aim is to assess the trends in the prevalence of current recommendations for the screen time ( Conclusions: As screen time is an important indicator of time spent in a sedentary way, our findings call for more interventions to reduce the time that school-aged children spend in front of screens.

“…In addition, these results are limited and vary between countries (23)(24)(25)(26)(27). Some studies reported a consistent amount of the total time spent sitting in front of a television or a computer, and they reveal that the time spent watching television was replaced by time spent using a computer (28,29).…”

“…Among the screen-based behaviors, TV viewing has been more related to negative cardiovascular health compared to PC/ VG 27 , which we extend to mental health. Interestingly, while prevalence of TV viewing declined, PC/VG use increased among Brazilian young people between 2001 and 2011 42 . Although more studies are warranted, the above information could help in the formulation of specific interventions to reduce sedentary behaviors, beginning with the most harmful.…”

-Aim:To analyze the association between screen-based sedentary behaviors, mental health, and social relationships in Brazilian adolescents. Methods: A representative sample of the adolescents from Londrina/PR was selected (n = 1,158; 10 to 17 y). Weekday and weekend screen time (TV-viewing and computer/video-game), mental health indicators (self-rated health, stress, feelings of sadness, and satisfaction with own body), and perceived social relationships (friends, family, and teachers) were collected through questionnaires. Somatic maturation, body mass index, and physical activity were assessed as covariates. Results: Adolescents who reported higher TV-viewing presented higher odds (p < 0.05) for poor self-rated health (boys), higher stress (both sexes), and dissatisfaction with own body (boys), friendships (girls), and teachers (girls). In contrast, higher computer/video-game use was associated with lower odds (p < 0.05) for poor self-rated health (girls), higher stress (boys), feelings of sadness (both sexes), and dissatisfaction with friends (both sexes) and family (both sexes). Conclusion: While higher TV-viewing is associated with negative outcomes, higher computer/video-game users demonstrate better mental health and lower satisfaction with their social relationships.

“…Silva et al 8 found that exposure to TV reduced, while exposure to PC/ VG increased from 2001 to 2011 in the state of Santa Catarina, in southern Brazil. Lopes et al 9 reported in literature that these changes were similar between boys and girls, but were stronger on weekend days. However, since sociodemographic factors are associated with different changes in patterns of TV or PC/VG use 8 , and access to electronic devices varies between states and cities (i.e., due to socioeconomic inequalities 10 ), such results cannot be extrapolated to other regions of Brazil (e.g., northern).…”

“…In Brazil, changes in the patterns of exposure to screen time in adolescents have been addressed in few studies [8][9] . Silva et al 8 found that exposure to TV reduced, while exposure to PC/ VG increased from 2001 to 2011 in the state of Santa Catarina, in southern Brazil.…”

-Aim: to analyze the pattern and trends of use of screen-based devices and associated factors from two surveys conducted on public high school students in Caruaru-PE. Methods: two representative school-based crosssectional surveys conducted in 2007 (n=600) and 2012 (n=715) on high school students (15-20 years old). The time of exposure to television (TV) and computer/videogames PC/VG was obtained through a validated questionnaire, and ≥3hours/day was considered as being excessive exposure. The independent variables were socioeconomic status, school related, and physical activity. Crude and adjusted binary logistic regression were employed to examine the factors associated with screen time. The statistical significance was set at p<0.05. Results: There was a significant reduction in TV time on weekdays and total weekly, but no change in the prevalence of excessive exposure. The proportion of exposure to PC/VG of ≥3 hours/day increased 182.5% on weekdays and 69.5% on weekends (p <0.05). In 2007, being physically active was the only protection factor for excessive exposure to total screen time. In 2012, girls presented less chance of excessive exposure to all screen-based devices and total screen time. Other protective factors were studying at night and being physically active (PC/VG time), while residing in an urban area 41)] and having higher family income [OR 1.55(1.04-2.30)] were risk factors. Conclusion: Significant and important changes in the time trends and pattern of use PC/VG were observed during the interval of 5 years. This rapid increase could be associated with increased family income and improved access to these devices, driven by technological developments.

Changes in television viewing and computers/videogames use among high school students in Southern Brazil between 2001 and 2011

Abstract: After a decade, there was a decrease in the prevalence of TV viewing and an increase in computer/videogame use. Socio-demographic factors were differently associated with these behaviors.
