Abstract 13979: A Gradual Taste Adaptation Strategy Improved Adherence to the Low Sodium Diet among Patients With Heart Failure
Introduction: Despite the importance of the low sodium diet (LSD) to the management of patients with heart failure (HF), adherence to LSD remains poor. A step-by-step, gradual taste adaptation to the LSD is an innovative approach to promoting increased acceptance of the LSD. The purpose of this study was to examine whether gradual taste adaptation approach to LSD (i.e. Sodium Watcher Program) resulted in reduction in sodium intake and improved self-care, perceived control, and quality of life.
Methods: A total of 39 (64% male, mean age 60 years) patients who were not adherent to LSD (24-hour urinary sodium excretion [24h UNa] >3000mg) at baseline were randomly assigned to Sodium Water intervention (n=20) or control (n=19). The intervention group received 6-weeks of self-care education for HF and LSD. Patients in the intervention were helped to set their own weekly goals for sodium intake and slow reduction of salt intake by monitoring the sodium content in food using an electronic sodium monitoring device. At 2 months follow up, adherence to LSD was assessed using 24h UNa. Self-care of HF, perceived control, and quality of life were assessed using the European Self-care Questionnaire-9, the Control Attitude Scale-Revised, and the Minnesota Living with Heart Failure Questionnaire, respectively. Repeated measures ANOVA was used to compare group differences from pre-to post-intervention.
Results: The intervention group had a significant 23% reduction in 24h UNa (pre vs. post-intervention, 5109 vs. 3946 mg, p=.02) and significant improvement in self-care (31.2 vs. 27.8, p=.039), perceived control (31.2 vs.32.9, p=.031) and quality of life (46.7 vs. 35.6, p=.022) at 2-month follow up.There were no differences in 24h UNa, perceived control, or quality of life in the usual care group. The usual care group improved in self-care at 2-month follow up (24.7 vs. 22.6, p=.047).
Conclusion: This pilot study demonstrated that a gradual adaptation approach was effective in reducing sodium intake and improving self-care, perceived control and quality of life. Helping patients adapt to the taste of a lower sodium diet may have potential for promoting long-term adherence but this needs to be tested in a larger clinical trial.
