Interrelationships of adolescent physical activity, screen-based sedentary behaviour, and social and psychological health

Abstract

Summary Objectives To examine how adolescent physical activity (PA) and screen-based media sedentary behaviours (SBM) relate to psychological and social health and identify cross-national differences in these relationships. Methods Associations were examined in five regions using two Health Behaviour in School-Aged Children (HBSC) countries from each. Results Self-reported psychological and social health indices such as self-image, perceived health status, and quality of life were positively related to PA in all five regions but, with a few exceptions, negatively related to SBM. Negative health indices such as health complaints and tobacco use were negatively related to PA but, with exceptions, positively related to SBM. Significant regional differences were present. Conclusions Regional differences in correlates of PA and SBM suggest cultural differences in potential effects of PA and SBM and the need to tailor school and public health efforts to the different meanings of PA and SBM for positive and negative health consequences.

Screen-based sedentary behaviors, mental health, and social relationships among adolescents

“…However, there are also indications that specific types of screen time can have positive effects on social and mental outcomes 14 . Thus, in addition to understanding the impacts of different types of screen time, other knowledge gaps persist regarding the relationship between these exposures and mental health indicators, such as the gradual relation (dose-response), differences between sexes 15 , and cultural contexts 16 . In this sense, our aim was to analyze the association between screen time (TV, computer, and video-game), mental health, and social relationships in Brazilian adolescents.…”

Exercise during early, but not late abstinence, attenuates subsequent relapse vulnerability in a rat model

“…Epidemiological studies have long reported negative associations between levels of physical activity and illicit drug use. 4,5 There are also many anecdotal reports suggesting that people in recovery turn to exercise to help maintain abstinence. Exercise has been shown to reduce symptoms of depression and measures of anxiety, and to enhance cognition, 6,7 factors known to contribute to drug relapse.…”

“…We also compared the effects of early or late exercise to the effects of access to a locked or unlocked wheel throughout abstinence (days [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. On the basis of the neurobiological data, 29,33,38 we predicted that exercise during early abstinence would cause a greater decrease in cocaine seeking as compared with exercise during late abstinence.…”

Screen-based behaviour in Czech adolescents is more prevalent at weekends

“…(Iannotti et al, 2009). One of the main reasons for recent scientific interest in SB is the relationship between SB and risk of being overweight or obese.…”

“…For example, across countries and age groups, a positive relationship between SB and the number of friends, the time spent with friends, and the quality of peer relationships was found (Iannotti et al, 2009;Kuntsche et al, 2009). …”
