Low sodium diet for gastric cancer prevention in the United States: Results of a Markov model
Published in Cancer Medicine on 1st December 2020, Kim et al modelled the impact and cost-effectiveness of the low sodium-DASH diet for prevention of gastric cancer in the U.S. population. Compared to no intervention, the study found the low sodium-DASH diet could reduce gastric cancer risk by 24.8% for males and 21.2% for females and approximately 27 and 14 cases of gastric cancer per 10,000 individuals were prevented for males and females respectively. The incremental cost-effectiveness ratio (ICER) exceeded a willingness to pay threshold of $100,000/QALY for the low sodium-DASH diet, however it was found to be cost-effective for high-risk populations compared to the average 40 year old in the U.S.
