Associations between objective ly measured total sedentary time and indicators of adiposity and motor development were predominantly null .
Associations between screen time and indicators of adiposity , motor or cognitive development , and psychosocial health were primarily unfavourable or null .
Associations between time spent seated ( e.g. , in car seats or strollers ) or in the supine position , and indicators of adiposity and motor development , were primarily unfavourable or null .
Conclusions These findings continue to support the importance of minimizing screen time for disease prevention and health promotion in the early years , but also highlight the potential cognitive benefits of interactive non-screen-based sedentary behaviours such as reading and storytelling .
Background The purpose of this systematic review was to examine the relationships between  sedentary behaviour ( SB ) and health indicators in children aged 0 to 4 years , and to determine what doses of SB ( i.e. , duration , patterns [ frequency , interruptions ] , and type ) were associated with health indicators .
The Cochrane Collaboration’s tool for assessing risk of bias in randomised trials
Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more
