Abstract
Introduction: The Informed Health Choices (IHC) secondary school intervention aimed to teach students to assess claims about treatments. This follow-up of a cluster randomized trial assessed the retention of knowledge and the application of the nine prioritized IHC key concepts 1 year after the intervention.
Methods: We conducted a random assignment of 80 secondary schools in Western Kenya into either the intervention (n = 40) or control (n = 40) group. Both groups adhered to the standard curriculum. Teachers from the intervention group were invited to participate in a 2-day training workshop and were granted access to "Be Smart About Your Health" digital resources, comprising 10 lessons. These lessons, focused on nine prioritized IHC concepts, delivered over a single school term from May to August 2022. The digital resources were accessible online via smartphones or computers and could also be downloaded for offline use. The primary outcome measure, assessed at the end of the school term and again after 1 year, was the percentage of students achieving a passing score (defined as ≥ 9 out of 18 correct answers) on the "Critical Thinking about Health" test.
Results: Out of the total 3360 students involved in the trial, 2446 (72.8%) completed the test after 1 year. Within the intervention group, 728 out of 1369 students (53.2%) achieved a passing score after 1 year, compared to 61.7% immediately post-intervention. In contrast, in the control group, 347 out of 1077 students (32.2%) had a passing score after 1 year. The adjusted difference in passing rates between the intervention and control groups after 1 year was 20.8% (with a 95% confidence interval of 13.6 to 28.0%), compared to 27.3% (with a 95% confidence interval of 19.6 to 34.9%) immediately after the intervention.
Conclusion: This study demonstrates that students were able to retain knowledge and the ability to apply the IHC key concepts, 1 year after the intervention. But fewer students in the intervention group had a passing score after 1 year compared to just after the intervention. Highlighting follow-up training is likely necessary to reinforce these skills over time.

期刊介绍：
Trials is an open access, peer-reviewed, online journal that will encompass all aspects of the performance and findings of randomized controlled trials. Trials will experiment with, and then refine, innovative approaches to improving communication about trials. We are keen to move beyond publishing traditional trial results articles (although these will be included). We believe this represents an exciting opportunity to advance the science and reporting of trials. Prior to 2006, Trials was published as Current Controlled Trials in Cardiovascular Medicine (CCTCVM). All published CCTCVM articles are available via the Trials website and citations to CCTCVM article URLs will continue to be supported.
