Persistent socio-demographic differences in physical activity among Scottish schoolchildren 1990-2002.

Background: Regular participation in physical activity can have significant health gains in terms of physical and psychological wellbeing but there is evidence to suggest that many young people are not sufficiently active to benefit their health. This paper examines the socio-demographic patterning of leisure-time vigorous physical activity among Scottish schoolchildren between 1990 and 2002.

Methods: The Health Behaviour in School-Aged Children survey of 11-, 13- and 15-year-old schoolchildren has been carried out in Scotland since 1990 at four-yearly intervals.
