The effect of physical activity advice given in routine primary care consultations: a systematic review.

Recent evidence and recommendations suggest that physical activity health promotion should be aimed at persuading the whole population to adopt an active lifestyle. Intensive medical programmes aimed at promoting physical activity amongst those at risk are not effective at achieving this aim. Brief advice from primary care professionals to quit smoking has a small but, at a population level, important effect. Brief advice in primary care to adopt a more active lifestyle may be similarly effective. The aim of this review is to determine the effect of advice given in routine primary care consultations on levels of physical activity.
