Joint Association of Screen Time and Physical Activity with Obesity: Findings from the Korea Media Panel Study

Abstract

ObjectivesThere is evidence to suggest that sedentary behavior is associated with a higher risk of metabolic disease. The aim of this study was to investigate cross-sectional joint associations of physical activity (PA) and screen time (ST), with the risk of obesity in Korean adults.MethodsThe Korea Media Panel Study consisted of a household interview and a self-administered diary survey on media usage over 3 days. ST (hours/day) was defined as the reported daily average hours spent watching television, computing (i.e., desktop, notebook, netbook, tablets), smartphone and video game console use. Cross-sectional associations of obesity (BMI ≥ 25 kg/m2) and the amount of daily ST and PA were examined by logistic regression models adjusting for other possible confounders including alcohol consumption, smoking, depressive symptoms and demographic information. There were 7,808 participants included in the analyses.ResultsIncreased ST was significantly associated with the risk of obesity (controlling for other possible confounders), but PA level was not found to be significantly linked. Participants who engaged in screen time > 6 hours per day had a higher incidence of obesity.ConclusionThis study provides evidence of the association between ST and the increased incidence of obesity measured by BMI, independent of PA amongst Korean adults.

Association of total sedentary behaviour and television viewing with risk of overweight/obesity, type 2 diabetes and hypertension: A dose–response meta‐analysis

“…Eight articles reporting more than one health outcome were treated as independent studies . Among these studies, 21 studies (six cohort and 15 cross‐sectional studies) examined the association between total sedentary behaviour and overweight/obesity, 23 studies (13 cohort and 10 cross‐sectional studies) examined the association between total sedentary behaviour and type 2 diabetes, and 14 studies (one cohort and 13 cross‐sectional studies) examined the association between total sedentary behaviour and hypertension . Ten studies were conducted in North America, two in South America, nine in Australia, 18 in Europe, seven in Asia, and two in other regions .…”

The Association between Esports Participation, Health and Physical Activity Behaviour

“…It has been shown that higher levels of video game addiction were associated with increased abdominal obesity [ 9 ], due to disturbed sleeping patterns. Increased screen time in adults has also been associated with higher BMI, a finding shown to be independent of PA behaviour [ 13 ]. Overall, there appears to be a positive correlation between sedentary lifestyles and obesity [ 13 , 14 , 15 ].…”

A Multinomial Logistic Regression Examination of TV Time and Two Different Measures of Obesity in U.S. Adults

“…Moreover, health education efforts to combat obesity have focused on physical activity and energy balance intervention [12,13,14]. Screen time (combined use of technology devices with screens) is a measure of sedentary behavior that is also related to obesity in adults [15,16,17]. Given this background, few studies have inspected the relationship between specific forms of screen time and obesity measured using multiple assessments.…”
