 The study aimed to assess the feasibility of a complex behavioral intervention to lower salt intake in people with elevated blood pressure and test trial procedures for a randomized controlled trial. The intervention was developed using the behavior change wheel and comprised individualized, brief advice from a health care professional with the use of the SaltSwap app. The study found that the intervention was acceptable and feasible to deliver within primary care, and there was sufficient signal of potential efficacy to change salt intake behaviors. With some improvements to the intervention app, a larger trial to assess intervention effectiveness for reducing salt intake and blood pressure is warranted.
