Objectives:
Systematic reviews of case-control studies evaluating the relationship between dietary salt intake and gastric cancer showed a positive association, however a quantitative analysis of longitudinal cohort studies is lacking. Therefore, this review article has been conducted.
Does a high salt intake increase gastric cancer risk?
Study design:
This review article contained 10 cohort studies with 268,718 participants, of which 1,474 gastric cancer events and a follow-up of 6-15 years.
Meta-regression analyses did not detect specific sources of heterogeneity.
There was no evidence of publication bias.
Results and conclusions:
The investigators found for high vs low salt intake a significantly increased risk of 68% for gastric cancer [RR = 1.68, 95% CI = 1.17 to 2.41, p = 0.005].
The investigators found for moderate vs low salt intake a significant increased risk of 41% for gastric cancer [RR = 1.41, 95% CI = 1.03 to 1.93, p = 0.032].
The investigators found the association was stronger in the Japanese population and higher consumption of selected salt-rich foods was also associated with greater risk.
The investigators concluded high salt intake is directly associated with an increased risk of gastric cancer in prospective population studies, with progressively increasing risk across consumption levels.
