For a research, researchers sought to investigate the affiliation amongst display screen time and teenagers’ possibility of chubby/obesity. Until September 2021, a systematic research of electronic databases, such as PubMed, Embase, and Scopus, was performed. All printed investigation analyzing monitor time and adolescent over weight/weight problems threat was collected. Finally, 44 scientific tests that happy the inclusion conditions have been bundled in the meta-examination. The 2-course meta-evaluation unveiled that adolescents in the maximum category of screen time ended up 1.27 times extra likely to acquire obese/weight problems (OR=1.273 95% CI=1.166–1.390 P<0.001 I-squared (variation in ES attributable to heterogeneity)=82.1%). The subgrouping results revealed that the continent and context were potential drivers of variation. In addition, there was no evidence of a non-linear relationship between increased screen time and the incidence of overweight/obesity among teenagers (P-nonlinearity=0.311). Without dose-response data, the current systematic review and meta-analysis revealed for the first time a positive connection between screen time and overweight/obesity among teenagers.
