Relationship between salt reduction readiness and salt intake in hypertensive patients: a single nonspecialized hypertension clinic case study

This is the first report about the association of readiness for salt reduction with daily salt intake or the salt check sheet score in hypertensive patients at a nonspecialized hypertension clinic. We investigated whether salt reduction readiness as evaluated based on the transtheoretical model (TTM) is associated with estimated daily salt intake or the salt check sheet score. The TTM allows evaluators to easily assess a subject's level of readiness for health-related according to five stages. There was no significant relationship between the TTM stages and estimated daily salt intake. A significant correlation was found between the TTM stages and salt check sheet scores (ρ = -0.409; P < 0.001). When providing salt reduction guidance to hypertensive patients, it is effective for healthcare professionals to use repeated urine tests and salt check sheets to take a salt reduction approach according to the level of readiness of the patients.
