health policy

In Scotland in recent years smoking, poor diet and excess alcohol have caused major public health problems. Knowledge of what is effective in the field of health behaviour change is therefore essential in achieving improvements in health. This symposium was convened with the purpose of ensuring that public health policy is informed by the best available evidence on effective interventions. As behaviour is complex, achieving change can be difficult and it is essential that interventions are properly planned, implemented and evaluated.

This review is based on a presentation by Professor Hankey at the RCPE Neurology Symposium on 27 November 2009.

Keywords Evidence, health policy, ischaemic stroke, prevention, randomised trials, treatment
