Mass media campaigns improve population health by promoting positive health behaviours and discouraging negative ones.1 Campaigns have helped to successfully reduce smoking and promote physical exercise. For some health conditions, campaigns sometimes have to compete with the marketing of unproven tests and treatments by industry and professional associations. An example of success in this context was an Australian campaign that improved population and general practitioner beliefs about back pain, improved medical management, and reduced workers' compensation costs for back pain.
