Abstract
Stomach cancer (SC) is the most common cancer among males in Madras, India, and its incidence rate is higher than that seen in Northern India. Epidemiological studies have shown low consumption of fresh vegetables and fruits, and high intake of pickled vegetables, starchy, and salted food as major risk factors for stomach cancer. To identify reasons for the intraregional differences in the incidence rates of stomach cancer in India a multicenter study was carried out. A hospital-based, case-control study as part of a multicenter study was conducted at the Cancer Institute (WIA), Madras, on 388 incident cases of SC. The cases were matched to cancer controls based on age (± 5 years), sex, religion, and mother tongue. The following variables were included in all models to control for confounding effect: income group, level of education, and area of residence. The food group analysis showed those in the highest quartile of consumption of fried foods (vegetables and/or meat) and salty food had a two- to fourfold risk compared to those in the lowest quartile of consumption. The protective effect of vegetables increased with increase in the frequency of consumption (highest vs. lowest quartile OR = 0.5; 95% CI = 0.33-0.68). In the analysis of individual food items, consumption of eggfry ( Keywords: CASE-CONTROL STUDY; DIET; EPIDEMIOLOGY; RISK FACTORS Document Type: Research Article DOI: http://dx.doi.org/10.3727/108399896792195455 Publication date: 1996-06-01 $(document).ready(function() { var shortdescription = $(".originaldescription").text().replace(/\\&/g, '&').replace(/\\, '<').replace(/\\>/g, '>').replace(/\\t/g, ' ').replace(/\\n/g, ''); if (shortdescription.length > 350) { shortdescription = "" + shortdescription.substring(0,250) + "... more"; } $(".descriptionitem").prepend(shortdescription); $(".shortdescription a").click(function(e) { e.preventDefault(); $(".shortdescription").hide(); $(".originaldescription").slideDown(); }); }); GA_googleFillSlot("Horizontal_banner_bottom");
