“…Also, in this study we observed that GC patients' intake of total fat, SFA, beef, lamb meat and salt were significantly higher compared to controls. In line with our study, several studies (17), including meta-analysis studies (23,24), have shown that high intake of total fat and SFA are associated with increased risk of GC. However, it should be noted that some studies (25) have not observed a significant association between total fat and SFA intake and GC risk.…”

Background: Gastric cancer (GC) is the fourth major malignancy and the second leading cause of cancer-related deaths worldwide. Northern and northwestern areas of Iran are among the high risk areas for GC. Studies have shown that dietary components are implicated in the etiology of GC. The index of nutritional quality (INQ) is a method of quantitative and qualitative analysis of single foods, meals, and diets. We aimed to assess the association of INQ with GC, and to evaluate the nutrient intake of GC patients. Methods: The present case-control study included 82 cases and 95 healthy controls attending specialized centers in Tabriz, Iran, from December 2014 to May 2016. INQ scores were computed based on dietary intake assessed using a validated 168-item food frequency questionnaire (FFQ). Logistic regression models were used to estimate multivariable ORs adjusted age, gender, BMI, smoking, residency, education, and regular physical activity. Results: After controlling for several covariates, inverse associations were observed between GC risk and INQs of vitamins A, B6, and D (ORvitA = 0.25 (0.06 -0.98); ORvitB6 = 0.10 (0.04 -0.28); and ORvitD = 0.14 (0.02 -0.84)). Cases had higher intake of total fat, saturated fatty acids, beef, lamb meat, salt, and paprika compared to controls. On the other hand, controls had higher intake of vitamin A, vitamin, vitamin B6, copper, poultry, low fat milk, tea, coffee, turmeric, and saffron compared to cases. Conclusions: Subjects who follow a more healthy and nutrient-rich diet, especially in terms of vitamins A, B6, and D, are at lower risk of having GC, compared to those who consume a more unhealthy, nutrient-poor diet.

Tobacco smoking is a known cause of gastric cancer, but several aspects of the association remain imprecisely quantified. We examined the relation between cigarette smoking and the risk of gastric cancer using a uniquely large dataset of 23 epidemiological studies within the 'Stomach cancer Pooling (StoP) Project' , including 10 290 cases and 26 145 controls. We estimated summary odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) by pooling study-specific ORs using random-effects models. Compared with never smokers, the ORs were 1.20 (95% CI: 1.09-1.32) for ever, 1.12 (95% CI: 0.99-1.27) for former, and 1.25 (95% CI: 1.11-1.40) for current cigarette smokers. Among current smokers, the risk increased with number of cigarettes per day to reach an OR of 1.32 (95% CI: 1.10-1.58) for smokers of more than 20 cigarettes per day. The risk increased with duration of smoking, to reach an OR of 1.33 (95% CI: 1.14-1.54) for more than 40 years of smoking and decreased with increasing time since stopping cigarette smoking (P for trend < 0.01) and became similar to that of never smokers 10 years after stopping. Risks were somewhat higher for cardia than noncardia gastric cancer. Risks were similar when considering only studies with information on Helicobacter pylori infection and comparing all cases to H. pylori + controls only. This study provides the most precise estimate of the detrimental effect of cigarette smoking on the risk of gastric cancer on the basis of individual data, including the relationship with dose and duration, and the decrease in risk following stopping smoking.

Golestan province has a reputation for relatively high incidence rates of gastric cancer in Iran. Along with dietary, lifestyle and environmental influential factors, soil selenium and high levels of pesticide used may exert influence in this region. The present study was designed for modeling the influential predictors on incidence of gastric cancer in Golestan. All registered cases of gastric cancer from March 2009 to March 2010 (49 females and 107 males) were investigated. Data were gathered by both check list and researcher made questionnaire (demographic, clinical and lifestyle characteristics) and analysed using logistic regression. Mean (±SD) age at diagnosis was 62.9±13.8 years. CIR and ASR of gastric cancer showed 9.16 and 13.9 per 100,000 people, respectively. Based on univariate logistic regression, a history of smoking (OR= 2.076), unwashed hands after defecation (OR= 2.612), history of cancer in relatives (OR= 2.473), history of gastric cancer in first-degree relatives (OR= 2.278), numbers of gastric cancers in first-degree relatives (OR= 2.078), history of X-ray and dye exposure (OR= 2.395), history of CT scan encounter (OR= 2.915), improper food habits (OR= 3.320), specific eating behavior (OR= 0.740), consumption of probable high risk foods (OR= 2.942), charred flesh (OR= 1.945), and animal fat (OR= 2.716) were confirmed as a risk factors. Changes in lifestyle may be expected to increase gastric cancer incidence dramatically in the near future. Therefore, appropriate educational interventions should be designed and implemented by competent authorities
