BACKGROUND: Esophageal cancer (EC) is ranked as the top 10th malignancy in China; however, an association between peanut consumption and EC risk has not yet been identified. This study explored the protective effects of peanut consumption against the risk of developing esophageal squamous cell carcinoma (ESCC) in a high-risk area.
METHODS: A case-control design was applied, with frequency matching by age and gender. A logistic regression model was used to estimate odds ratios (OR) and 95% confidence intervals (CI). Two hundred and twenty-two cases and 222 controls were recruited from Yanting County from 2011 to 2012.
RESULTS: Peanut consumption 1-3 times per week reduced cancer risk by 38% (OR 0.62, 95% CI 0.34-1.13), while consumption ≥ 4 times per week reduced the risk by 70% (OR 0.31, 95% CI 0.16-0.59). A significant association was observed among individuals with negative family EC history (OR 0.25, 95% CI 0.12-0.49).
CONCLUSION: Peanut consumption may act as a protector against the occurrence of ESCC in high-risk areas, thus production and consumption should be promoted in high-risk areas in order to reduce the ESCC burden.
