Diet and stomach cancer incidence a case–control study in Turkey

Abstract

A case-control study of diet and stomach cancer was conducted in Ankara, Turkey, between December 1987 and March 1988. One hundred patients with adenocarcinoma of the stomach were matched with 100 control subjects according to age, sex, and residential area. A dietary questionnaire was administered to all subjects by one of the authors. Gastric cancer patients consumed less fresh fruit and yellow-green vegetables (P < 0.000~) and meats (P < 0.001), and more salted food (P < 0.001), condiments (P < o . o O O~) , and salt (P < 0.001) compared with the control group. Twenty-four percent of the gastric cancer patients and 4% of the controls had no refrigerator (P < 0.000~). There was no difference between the two groups with regard to the consumption of starches, fried foods, cereals, milk, dairy products, tea, alcohol, and tobacco. Stomach cancer patients brushed their teeth less frequently (P < 0.000~) and had more deficient teeth (P < 0.000~) compared with the control group. Cancer 65:2344-2348,1990.

“…Duration of refrigerator use or freezer use was not associated with stomach cancer risk in the Netherlands Cohort Study, in contrast with the results of casecontrol studies performed in Europe or the USA, which rather consistently reported a decreased stomach cancer risk with long-term use of a refrigerator [2,5,9,16,18,38,54]. Three of the case-control studies did not find an association [15,44,47] and no other cohort study reported on this association.…”

“…Overall, in the majority of case-control studies, positive associations were observed for (total) salt or sodium intake [2,3,33,34], consumption of salted fish, salted meat, pickles and soup [5,7,16,[34][35][36][37][38][39][40], adding salt to food at dinner [5,9,41], preference of salty foods [4,5,11,40,42]. The relative risks reported ranged from 1.5 to 6.7 for various measures of salt intake [14].…”

Evaluation of Dietary and Life-Style Habits of Patients with Gastric Cancer: A Case-Control Study in Turkey

“…The majority of patients with gastric cancer were men (62.3%) with a men/women ratio of 1.65 in our study. In another casecontrol study conducted in Turkey by Demirer et al (1990), 64% of patients with gastric cancer were men and 36% were women.…”

Correlation of Cancer Incidence with Diet, Smoking and Socio-Economic Position Across 22 Districts of Tehran in 2008

“…Various risk factors have been recognized such as helicobacter pylori (H pylori) infection, cured meat, smoking, and alcohol while Mediterranean diet, vegetables and fruits, vitamin C, retinol and high intake of cereal fiber decrease the risk of stomach cancer (Kolonel et al, 1981;Demirer et al, 1990;Schottenfeld and Fraumeni, 2006;Wang, 2009;Gonzalez and Riboli, 2010). An ecologic analysis in Brazil suggested that differences in living standards among populations probably have an important role in incidence differences (Koifman and Koifman, 1997).…”
