Systematic Review of the Relationships between Sedentary Behaviour, Physical Activity and Health Indicators in the Early Years

Two new reviews have been carried out investigating the link between sedentary behaviour, physical activity and health indicators.

  1. Systematic review of the relationships between sedentary behaviour and health indicators in the early years (0-4 years). Poitras VJ, Gray CE, Janssen X, Aubert S, Carson V, Faulkner G, Goldfield GS, Reilly JJ, Sampson M, Tremblay MS. BMC Public Health. 2017 Nov 20;17(Suppl 5):868. doi: 10.1186/s12889-017-4849-8.The review supports the importance of minimizing screen time for disease prevention and health promotion in the early years, but also highlights the potential cognitive benefits of interactive non-screen-based sedentary behaviours such as reading and storytelling. Additional high-quality research using valid and reliable measures is needed to more definitively establish the relationships between durations, patterns, and types of SB and health indicators, and to provide insight into the appropriate dose of SB for optimal health in the early years.
  2. Systematic review of the relationships between physical activity and health indicators in the early years (0-4 years). Carson V, Lee EY, Hewitt L, Jennings C, Hunter S, Kuzik N, Stearns JA, Unrau SP, Poitras VJ, Gray C, Adamo KB, Janssen I, Okely AD, Spence JC, Timmons BW, Sampson M, Tremblay MS. BMC Public Health. 2017 Nov 20;17(Suppl 5):854. doi: 10.1186/s12889-017-4860-0. This review concludes that specific types of physical activity, total physical activity, and physical activity of at least moderate- to vigorous-intensity were consistently favourably associated with multiple health indicators.
