Examining the hazards of sedentary behavior: An overview of the risks of screen-based sedentary behavior

Abstract

Screen-based sedentary behaviors (SSB) has become a particularly concerning subset of sedentary behavior. With the rapid advancement of technology, screens have become an integral part of our daily lives. However, the potential health impacts that accompany this trend demand our attention. Increasing evidence suggests that screen-based sedentary behavior, as opposed to traditional sedentary activities like reading, has more severe implications for health. Prolonged SSB in children and adolescents is associated with poorer physical fitness and cardiovascular health, and it poses a higher risk of obesity compared to traditional sedentary behavior. The World Health Organizations sedentary behavior guidelines emphasize the importance of limiting SSB in children and adolescents (aged 5-17) and encouraging adults (aged 18-64) to reduce their screen-based sedentary time. Therefore, this review provides an overview of the health hazards (obesity, type 2 diabetes, mental health and sleep) associated with screen-based sedentary behaviour and its potential mechanisms of action. In addition, interventions to reduce SSB and their benefits are discussed and future research directions are suggested.
