Dose–response association of screen time-based sedentary behaviour in children and adolescents and depression: a meta-analysis of observational studies

Abstract

BackgroundDepression represents a growing public health burden. Understanding how screen time (ST) in juveniles may be associated with risk of depression is critical for the development of prevention and intervention strategies. Findings from studies addressing this question thus far have been inconsistent. Therefore, we conducted a comprehensive systematic review and meta-analysis of data related to this question.MethodsThe meta-analysis was conducted in accordance with the PRISMA guideline. We searched the electronic databases of PubMed, Web of Science and EBSCO systematically (up to 6 May 2015). OR was adopted as the pooled measurement of association between ST and depression risk. Dose–response was estimated by a generalised least squares trend estimation.ResultsTwelve cross-sectional studies and four longitudinal studies (including 1 cohort study) involving a total of 127 714 participants were included. Overall, higher ST in preadolescent children and adolescents was significantly associated with a higher risk of depression (OR=1.12; 95% CI 1.03 to 1.22). Screen type, age, population and reference category acted as significant moderators. Compared with the reference group who had no ST, there was a non-linear dose–response association of ST with a decreasing risk of depression at ST<2 h/day, with the lowest risk being observed for 1 h/day (OR=0.88; 95% CI 0.84 to 0.93).ConclusionsOur meta-analysis suggests that ST in children and adolescents is associated with depression risk in a non-linear dose–response manner.

Fruit and vegetable consumption, leisure‐time physical activity, and sedentary behavior among children and adolescent students in Uganda

“…The association between substance use and sedentary behavior has been reported by number studies (Iannotti, Janssen, Haug, Kololo, & Annaheim, 2010;Nelson, 2006;Peltzer, 2010). Generally, there is evidence of a protective association between physical activity and depression (Liu, Wu, & Yao, 2016). Generally, there is evidence of a protective association between physical activity and depression (Liu, Wu, & Yao, 2016).…”

Impact of antipsychotic medication on physical activity and physical fitness in adolescents: An exploratory study

“…Our data also show that all adolescents, but in particular those treated with antipsychotic medication as they have a significantly impaired speed of limb movement, abdominal muscle endurance and explosive muscle strength compared with healthy controls, should participate in activities (ACSM, 2013) that promote muscle strength on two or three days per week. Although it was not a focus of the current study, it is well established that sedentary inactivity is a strong contributor to overweight and lack of physical fitness (Tremblay et al, 2011) which increases the risk for depression in adolescents (Liu et al, 2015). Therefore, sedentary activities such as television viewing, computer and telephone use, and inactive video games should be discouraged and limited to o2 h per day.…”

Global Matrix 2.0: Report Card Grades on the Physical Activity of Children and Youth Comparing 38 Countries

“…Future research should be directed toward identifying dose-response relationships between total time spent in sedentary behaviors and health outcomes in children and youth, that will in turn inform the development of comprehensive sedentary behavior guidelines. In this regard, a recent meta-analysis by Liu et al 3 suggests that screen time in children and adolescents is associated with depression risk in a nonlinear dose-response manner.…”
