4.2. Energy supply and physical activity of children

There is some recent evidence that, when the energy intake of children is inadequate, before growth falls off, there is a decrease in physical activity. This is to be regarded as highly undesirable, because it limits the child's exploration of the environment and the development of social relationships.

There are numerous anecdotal accounts of apathy, with-drawnness, failure to make friends, etc. - effects that may produce a progressive handicap throughout life.

These considerations reinforce the need for studies on the physical activity of children in relation to energy intake and the development of appropriate methodology.
