Evidence Brief: Positive impacts of physical activity on the heath of the whole child released by Public Health Ontario
http://www.publichealthontario.ca/en/eRepository/Physical_Activity_Whole...

Physical activity plays a vital role in the health and well-being of people of all ages. For children and youth, regular participation in physical activity is important for establishing positive behaviours that can be maintained throughout the life course.

Unfortunately, it is estimated that only seven per cent of Canadian children and youth (ages 6-19) accumulate at least 60 minutes of moderate to vigorous physical activity at least six days a week.

This evidence brief asks “what are the positive impacts of physical activity on the heath of the whole child, i.e., including the physical, mental and social health well-being of the child?”

Evidence Brief: Impacts of and relationship between excessive dietary sodium consumption and childhood obesity released by Public Health Ontario
http://www.publichealthontario.ca/en/eRepository/Sodium_Childhood_Obesit...

The 2007 Statistics Canada Health Report , citing 2004 data, indicated that a high percentage of Canadian children consumed sodium daily at levels exceeding the tolerable upper intake level recommended by the Institute of Medicine and Health Canada. There is some evidence from cross-sectional studies that dietary sodium consumption exceeding these tolerable upper intake levels is linked to childhood obesity through a direct unidentified mechanism.

This Evidence Brief asks two questions:

  1. What are the long-term and short-term impacts of excessive dietary sodium consumption in children?
  2. What is the relationship (if any) between excessive dietary sodium consumption and childhood obesity?
