Dietary protein intake and stomach cancer, insights from a case-control study.

ABSTRACT: Studies on the role of protein intake in the development of stomach cancer (SC) remain controversial. This study examines the relationship between protein intake from whole foods and SC in a Vietnamese population. A case-control study was designed in the university hospitals in Hanoi, Vietnam, from 2003 to 2019. Participants included 1182 SC cases and 2995 controls. Of the participants, 2,580 were men, and 1,597 were women. Protein intake was assessed using a validated semi-quantitative food frequency questionnaire. The odds ratio and 95% confidence interval (OR, 95%CI) examined the risk of SC associated with total protein and subgroups of mammal-animals and fish-poultry protein. Overall protein intake was negatively associated with SC (fifth vs. first quintile: OR (95%CI): 0.41 (0.32, 0.5
