- This study was performed to investigate the association between coffee consumption and risk of colorectal cancer in a Korean population and examine whether the association can be altered by adjustment for intake of coffee additives. We conducted a case-control study involving 923 colorectal cancer cases and 1846 controls matched by sex and age (within 5 years). A semi-quantitative food frequency questionnaire was used to assess coffee intakes. High coffee consumption was associated with lower odds of developing colorectal cancer (>= 3 cups/day vs. no drinks, OR = 0.68; 95% CI: 0.49-0.96). When we additionally controlled for consumption of coffee additives including sugar and cream, the inverse association became stronger (>= 3 cups/day vs. no drinks, OR = 0.22; 95% CI: 0.14-0.33), and a significant inverse linear trend was shown (P-trend < 0.0001). The inverse associations were observed for proximal (P-trend = 0.0001) and distal (P-trend = 0.0003) colon cancer, and rectal cancer (P-trend < 0.0001) in the stratified analysis by anatomical sub-sites. Regarding sex, inverse associations between coffee consumption and colorectal cancer were found for men (P-trend < 0.0001) and women (P-trend = 0.0021). In the stratified analysis by obese status of subjects, inverse linear trends were observed in both non-obese and obese people (P-trend < 0.0001). High coffee consumption may be associated with a lower risk of colorectal cancer in the Korean population and the degree of decrease in the odds of developing colorectal cancer changes by adjustment for intake of coffee additives.
