Mass media campaigns may influence the use of health services. They can encourage people to use effective interventions and discourage them from using ineffective ones.
Mass media is an important way of providing information to the general public and is the leading source of information for health related issues. The World Health Organisation (WHO) recognises media advocacy as an established health promotion stategy. It is important to evaluate the effects of mass media on the use of health services.
