“…A stagnation or decline in time spent watching television was also observed among German adolescents (25), Australian children (43), US adolescents (24,31) and Brazilian adolescents (44); similar trends were observed in 29 (mostly European) countries involved in the HBSC study (45).…”

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.

“…This is in accordance with the results of the HELENA Study which found out that time spent in sedentary activities in adolescents was higher during weekends while boys spent more hours TV viewing and playing games and girls spent more time studying and surfing for non-study reasons (ReyLópez et al, 2010). Also the study by Lopes et al (2014) confirmed higher prevalence of screen based behaviour at weekends and highlighted the importance of monitoring the structure of SB where we can observe a significant increase in computer/video game use and inversely, a significant reduction in TV watching over the last 10 years. Hesketh et al (2014) also indicate that children are more sedentary on weekend mornings compared with weekdays but the reverse was true for weekend afternoons and evenings.…”

Background: One of the main reasons for recent scientific interest in screen-based behaviour (SB) is the relationship between SB and risk of being overweight or obese. The primary mechanism for overweight and obesity is an imbalance of energy intake versus energy expenditure and one reason for the interest in SB is its association with reduced energy expenditure relative to other activities. Objective: The aim of this study is to provide a basic overview of the level and structure of SB in Czech adolescents on the basis of age and gender while taking into account the differences between weekday and weekend screen based activities. Methods: Data from the Health Behaviour in School-aged Children (HBSC) study conducted in May-June 2010 in the Czech Republic were used. The sample consisted of 4365 Czech pupils (48.5% boys; age 11, n = 1406; age 13, n = 1446; age 15, n = 1513). Binomial logistic regression and Chi-square test of independence were used to provide basic comparison on the basis of gender and age groups. Results: The prevalence of SB rise with growing age with the most visible increase in prevalence is between ages 11 and age 13. SB is significantly more prevalent among adolescent boys compared with adolescent girls. Czech adolescents are more likely to not meet the recommendation of 2 hours for watching TV at weekends compared to weekdays. Playing computer games is more common among boys contrary to chatting online, which is more common among girls. The overall patterns of playing computer games and chatting online during weekends were similar to those at weekdays but increased. Conclusions: Most children in the Czech Republic do not meet the limit for total SB time of 4 or fewer hours while the prevalence of SB rises with growing age and at weekends. Interventions and strategies aiming at reducing SB in children focusing on the family and school environment in the Czech Republic are required.

“…The period of data collection and the region could explain, at least in part, these differences. Specifically in Brazil, the early years after 2000 were marked by changes in social and economic conditions; a combination of unemployment reduction, progressive increases in the minimum wage, and expansion of cash transfer programs 10 , which directly influenced the access to and use of electronic devices…”

“…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 fact, the PNAD report on access to internet, television, and cell phone use revealed marked changes in access to technology, consumption habits, and interactivity of Brazilians with screen devices, indicating differences between these regions and states 11 .…”

-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.

Trends in screen time on week and weekend days in a representative sample of Southern Brazil students

Abstract: The decrease in TV watching after a decade appears to be compensated by the increase in computer/video game use, both in boys and girls. Interventions are needed to reduce the negative impact of technological improvements in the lifestyles of young people, especially on weekend days.
