Objectives:
An increased risk of gastric cancer for pickled vegetable and salted fish intake has been suggested, yet the lack of a dose-response association warrants a quantitative analysis. Therefore, this review article (meta-analysis) has been conducted.
Do pickled vegetable and salted fish intakes increase risk of gastric cancer?
Study design:
This review article included 21 cohort studies with a total of 195,624 participants for the analysis of pickled vegetable intake and 16 cohort studies with a total of
196,384 participants for the analysis of salted fish intake.
Results and conclusions:
The investigators found in a dose-response meta-analysis of 6 studies, a significantly increased risk of 15% [combined RR = 1.15, 95% CI = 1.07 to 1.23, p for heterogeneity = 0.14] for gastric cancer incidence for a 40 g/day increment in pickled vegetable intake.
The investigators found in the categorical meta-analysis of 6 studies, a marginally significant increase in the risk of gastric cancer incidence, comparing the highest to the lowest intake of salted fish [RR = 1.17, 95% CI = 0.99 to 1.38, p for heterogeneity = 0.26].
The investigators concluded intake of 40 g/day of pickled vegetable increases risk of gastric cancer incidence.
