TL;DR: The evidence currently available to inform and advance the development of physical activity guidelines for Canadians is consolidated, and the specific needs of various population subgroups are highlighted.

TL;DR: Clinicians should direct greater attention to positive health, with particular reference to the role of physical activity, in optimising the well-being of a child, particularly if there is associated energy imbalance or emotional stress.

TL;DR: The results indicate that the body composition of participants in the Trois‐Rivières Growth and Development study developed in a similar fashion whether or not their primary school instruction included additional physical education instruction, and suggest that prediction of adult obesity based on childhood BMI measurements is more effective in girls than in boys.

TL;DR: It is shown that the twin explanations of this supposed phenomenon (a high intrinsic level of physical activity and an immaturity of biochemical systems) have little foundation, and in the average prepubescent it may be more important for the school programmes to develop positive, lifelong attitudes, than to maximise aerobic function.

TL;DR: In young children (who are less able to escape from ETS), the association between exposure and an increase in respiratory disease is stronger than in adults, and there is no strong evidence that pulmonary reactions have a psychogenic basis.
