Abstract 11727: Effects of Single Time Dietary Counselling by Dieticians on Salt Reduction in Cardiology Outpatients Who Consumed Large Amount of Salt
Introduction: Salt reduction is very difficult to achieve for individual patients as well as for the population.
Purpose: To assess the effects of single time dietary counselling by expert dieticians on salt reduction in Japanese cardiology outpatients.
Methods: A total of 72 patients (73 ±11 y/o, 30 female) who visited a cardiology outpatient clinic and took more than 8 g/day of salt were included in this study. They received dietary counselling for salt restriction by expert dieticians at the time of enrollment. The daily dietary salt intake (salt excretion) was estimated by spot urine before dietary counselling, during 3-9 weeks (next office visit), and during 24-56 weeks of follow-up.
Results: Hypertension was observed in 57 (79%), congestive heart failure in 16 (22%), and atrial fibrillation in 15 (21%) patients.The baseline estimated salt excretion was 11.3± 1.5 (range: 8.6-16.4) g/day, which was reduced to 9.6 ± 2.3 (range: 4.6-14.4) g/day (p<0.01) at 3-9 weeks, and partially returned to 10.4 ± 2.1 (range: 6.4-17.2) g/day at 24-56 weeks but was still smaller than the baseline value (p=0.034 vs 3-9 weeks, p=0.025 vs. baseline, figure). The number of patients in whom salt reduction was more than 2g/day from baseline was 29 (40%) at 3-9 weeks and 22 (31%, p=0.22 vs 3-9 weeks) at 24-56 weeks of follow-up. The number of patients who achieved salt excretion < 6.0 g/day and < 8.0 g/day was only 4 (5.7%) and 19 (27%) at 3-9 weeks and further reduced to none (0%, p=0.043 vs 3-9 weeks) and 9 (13%, p=0.035 vs 3-9 weeks) at 24-56 weeks follow-up, respectively.
Conclusion: The efficacy of salt reduction using single time dietary counselling by expert dieticians in patients who consumed large amount of salt was modest and temporary. Repeated dietary counselling may be a possible next step for further salt reduction.
