The Love Your Brain trial randomised 941 Australians aged 45 and over, with no prior cardiovascular event, to an online course, text messages or control. At 12 weeks, 41.3% in the text message arm reported a visit for cardiovascular risk assessment, as compared to 29.0% in control. The online course arm was 31.2%, and stroke knowledge rose in both intervention arms, although medication adherence and other behaviours did not differ.
Why it is interesting: A direct comparison of two information channels, where the lighter prompt moved behaviour and the fuller course did not.
