HALO Director Dr. Mark Tremblay is among the authors on a paper, âAssociation of screen time and cardiometabolic risk in school-aged childrenâ, that was just published in Preventive Medicine Reports. Using the TARGet Kids! cohort authors found there was no evidence of an association between parent-reported child screen time and total cardiometabolic risk, but increased screen time was associated with slightly lower HDL-c. Citation details and a summary of the paper are below.
Congratulations Mark and team!

Screen use has become a pervasive behaviour among children and has been linked to adverse health outcomes. The objective of this study was to examine the association between screen time and a comprehensive total cardiometabolic risk (CMR) score in school-aged children (7â12-years), as well as individual CMR factors. In this longitudinal study, screen time was measured over time (average duration of follow-up was 17.4Â months) via parent-report. Anthropometric measurements, blood pressure, and biospecimens were collected over time and used to calculate CMR score [sum of age and sex standardized z-scores of systolic blood pressure (SBP), glucose, log-triglycerides, waist circumference (WC), and negative high-density lipoprotein cholesterol (HDL-c)/square-root of 5]. Generalized estimating equations (GEE) were used to examine the association between screen time and total CMR score as well as individual CMR factors. A total of 567 children with repeated measures were included. There was no evidence of an association between parent-reported child screen time and total CMR score (adjusted Î˛Â =Â â0.01, 95% CI [â0.03, 0.005], 0.16). Screen time was inversely associated HDL-c (adjusted Î˛Â =Â â0.008, 95% CI [â0.011, â0.005],Â pÂ =Â 0.016), but there was no evidence that the other CMR components were associated with screen time. Among children 7â12Â years, there was no evidence of an association between parent-reported child screen time and total CMR, but increased screen time was associated with slightly lower HDL-c. Research is needed to understand screen-related contextual factors which may be related to CMR factors.
