Do personalised letters in Vietnamese increase cervical cancer screening among Vietnamese women?

In Australia, Vietnamese women are at greater risk of cervical cancer than other Australian women. To increase their participation in cervical screening, the Vietnamese community was exposed to a media campaign about the advantages of cervical smear screening which was delivered in Vietnamese through Vietnamese newspapers and radio. In addition, 689 Vietnamese (18–67 years) were selected from the electoral roll. They were randomly assigned to either receive a personal letter written in Vietnamese promoting cervical screening, or not. We report on the effect of the letter on smear rates.
Being randomised to be sent such a letter was not associated with any increase in screening (relative rate of appropriate screening in the intervention versus the control group was 0.85, 95% Cl 0.55–1.3). It is important to carefully evaluate untested health promotion interventions.
