Dietary factors play an important role in gastric cancer risk but have not been investigated extensively in Mexico.
The authors conducted a population-based case-control study of gastric cancer in the Mexico City, Mexico, metropolitan area in 1989-1990.
A total of 220 patients with histologically confirmed gastric adenocarcinomas were interviewed.
Controls were an age-stratified random sample of residents of the Mexico City metropolitan area.
The dietary questionnaire was a 70-item semiquantitative food frequency adapted for the Mexican diet.
Odds ratios were calculated for quartiles of consumption of food groups and were adjusted for age, gender, calories, chili pepper intake, cigarette smoking, socioeconomic status, added salt, and history of peptic ulcer disease.
There was approximately a threefold increased risk of gastric cancer for frequent consumption (highest quartile) of both fresh meat (odds ratio (OR)=3.1) and processed meat (OR=3.2).
Odds ratios were also significantly elevated for frequent consumption of dairy products (OR=2.7) and fish (OR=2.2).
The authors observed a decreasing gradient of risk with increasing frequency of vegetable consumption due to a significant inverse trend for the yellow and orange vegetables.
High intake of citrus fruits showed a slight inverse association.
Consumption of salty snacks more than twice per month was associated with an 80 percent increased risk, and there was a significant positive trend. (...)
