摘要
Objective: to explore the promoting effect of long-term consumption of potassium-enriched salt (KCL/NACL=1:1) on dietary salt restriction in the nursing home population. Design and method: In northern China, a total of 29 nursing homes were selected using cluster random sampling. The nursing homes were divided into intervention group (using potassium-enriched salt in the dining room) and control group (using regular salt in the dining room). The usage of salt and high-sodium condiments in the dining room was recorded, including the amount of salt used and the number of diners. The average per capita daily sodium intake from condiments (TNA/PD) in the nursing home was calculated, as well as the average per capita daily sodium intake from dietary salt (SNA/PD). The two values were added together to calculate the total per capita daily sodium intake (ANA/PD). Results: Over 6 years, a total of 18,046 meals were consumed in the dining room. The intervention group demonstrated a significant reduction in per capita daily sodium intake (ANA/PD) compared to the control group (3.0 vs 5.0g). There was no statistically significant difference in per capita daily sodium intake from condiments (TNA/PD) between the two groups, but the intervention group exhibited a significantly lower per capita daily sodium intake from dietary salt (SNA/PD) compared to the control group (2.2 vs 4.1g). Furthermore, the intervention group consistently maintained a lower urine sodium-to-potassium ratio than the control group. By incorporating potassium-enriched salt, the intervention group achieved an average increase of 1.2±0.31g in daily potassium intake. Subgroup analysis of 24-hour urine results indicated that the intervention group had significantly lower urinary sodium excretion and higher potassium excretion. Following one year of using potassium-enriched salt, the estimated dietary salt intake in the intervention group decreased from approximately 15g to around 9g based on urinary sodium excretion. Conclusions: These findings suggest that the utilization of potassium-enriched salt can effectively reduce sodium intake without necessitating alterations in dietary habits.
