“…When analysing the efficiency of two types of lowimpact training on screen time and BMI of overweight adolescents, Magalhães et al 10 revealed that there was no pre and post-intervention difference in screen time for the three groups, however, there was a reduction in BMI in both groups of exercises from the pre-post-training period.…”

Citizen care in the health field is a fundamental right provided by the federal constitution of Brazil. The Unified Health System (SUS) is one of the best and most important systems in the world and serves around 220 million people. The System is comprehensive and characterized by three pillars of support: universality, completeness and equity. The right to scientific information is one of the main elements of the SUS and the Journal of Human Growth and Development has contributed over its 27 years of existence providing a democratic scenario and a place to debate ideas in the field of public health and the irrefutable defence of SUS in Brazil. In this way, JHGD maintains its tradition of publishing articles devoted to the field of public health and contributing to the dissemination of knowledge and to the progress of science. The Journal intends to serve as a space for exchange knowledge among professionals in universities and help them to deal with the problems of human growth and development, improving the publication scenario of scientific articles refereed by peers, highlighting its commitment to communicate the knowledge obtained through ethic research with bilingual and free publications.Keywords: unified health system, information, science Suggested citation: Abreu LC, Pereira VX, Silva RPM, Junior HM, Bezerra IMP.

Background Excessive screen time ($$\ge$$ ≥ 2 h per day) is associated with childhood overweight and obesity, physical inactivity, increased sedentary time, unfavorable dietary behaviors, and disrupted sleep. Previous reviews suggest intervening on screen time is associated with reductions in screen time and improvements in other obesogenic behaviors. However, it is unclear what study characteristics and behavior change techniques are potential mechanisms underlying the effectiveness of behavioral interventions. The purpose of this meta-analysis was to identify the behavior change techniques and study characteristics associated with effectiveness in behavioral interventions to reduce children’s (0–18 years) screen time. Methods A literature search of four databases (Ebscohost, Web of Science, EMBASE, and PubMed) was executed between January and February 2020 and updated during July 2021. Behavioral interventions targeting reductions in children’s (0–18 years) screen time were included. Information on study characteristics (e.g., sample size, duration) and behavior change techniques (e.g., information, goal-setting) were extracted. Data on randomization, allocation concealment, and blinding was extracted and used to assess risk of bias. Meta-regressions were used to explore whether intervention effectiveness was associated with the presence of behavior change techniques and study characteristics. Results The search identified 15,529 articles, of which 10,714 were screened for relevancy and 680 were retained for full-text screening. Of these, 204 studies provided quantitative data in the meta-analysis. The overall summary of random effects showed a small, beneficial impact of screen time interventions compared to controls (SDM = 0.116, 95CI 0.08 to 0.15). Inclusion of the Goals, Feedback, and Planning behavioral techniques were associated with a positive impact on intervention effectiveness (SDM = 0.145, 95CI 0.11 to 0.18). Interventions with smaller sample sizes (n < 95) delivered over short durations (< 52 weeks) were associated with larger effects compared to studies with larger sample sizes delivered over longer durations. In the presence of the Goals, Feedback, and Planning behavioral techniques, intervention effectiveness diminished as sample size increased. Conclusions Both intervention content and context are important to consider when designing interventions to reduce children’s screen time. As interventions are scaled, determining the active ingredients to optimize interventions along the translational continuum will be crucial to maximize reductions in children’s screen time.

Several studies value the importance of technologies in everyday social processes, stressing loudly its positive effects for time control and management. However, the use of digital technology is increasingly said to co-produce the ways youngsters experience daily lives, as these are increasingly weaved in media hyperconnections, in several insidious and multiple forms, and in a continuous and enduring manner. This text focuses on the state of the art about the extension and nature of these co-productive processes, highlighting the effects of the technological means of communication on youngster's time representations and experiences, namely considering the social networks and other interactional devices that are now constituting increasingly more the individual identity, despite its intangibleness. The goal is to critically analyze the existing literature on time, technology, and youth, presenting its main contributions from a conceptual, methodological and practical point of view, including the use and the ways in media hyperconnections.

Effects of two types of low impact physical training on screen time among overweight adolescents

Abstract: Introduction:The time that adolescents spend in front of some screen as TV, computer, video games and mobile phones, has been considered a risk factor for obesity and non-communicable chronic diseases.
