AIM:To investigate gastric cancer screening and preventive behaviors among the relatives of patients with gastric cancer[i.e.,gastric cancer relatives(GCRs)].METHODS:We examined the Korean National Health and Nutrition Examination Survey 2005(KNHANESⅢ) database and compared the gastric cancer screening and preventive behaviors of GCRs(n=261)with those of non-GCRs(n=454)and controls without a family history of cancer(n=2842).RESULTS:The GCRs were more likely to undergo gastric cancer screening compared with the control group(39.2%vs 32.3%,adjusted odds ratio:1.43,CI:1.05-1.95),although the absolute screening rate was *** patterns and smoking rates did not differ significantly between the groups,and a high proportion of GCRs reported inappropriate dietary habits(i.e.,approximately 95%consumed excessive sodium,30% were deficient in vitamin C,and 85%were deficient in dietary fiber).CONCLUSION:The gastric cancer screening and preventive behaviors of GCRs have yet to be *** increase awareness among GCRs,systematic family education programs should be implemented.

AIM: To identify the factors associated with participation in gastric cancer screening programs. METHODS: Using data from the Korea National Health and Nutrition Examination Survey 2005 (KNHANES Ⅲ), a nationwide health-related surveyin Korea, a cross-sectional study was performed to investigate the multiple factors associated with gastric cancer screening attendance among persons aged at least 40 years. The study population included 4593 individuals who completed a gastric cancer screening questionnaire and had no previous cancer history. Four groups ofindividual-level or environmental level covariates were considered as potential associated ***: Using KNHANES Ⅲdata, an estimated31.71% of Korean individuals aged at least 40 years adhered to gastric cancer screening recommendations. Subjects who graduated from elementary school[adjusted odds ratio (aOR), 1.66; 95% CI: 1.21-2.26], middle/high school (aOR, 1.38; 95% CI: 1.01-1.89), and university or higher (aOR, 1.64; 95% CI: 1.13-2.37) were more likely to undergo gastric cancer screening than those who received no formal education at all. The population with the highest income tertile had more attendance at gastric screening compared to those with the lowest income tertile (aOR, 1.36; 95% CI: 1.06-1.73). Gastric screening was also negatively associated with excessive alcohol consumption (aOR, 0.71; 95% CI: 0.53-0.96). A positive attitude to preventive medical evaluation was significantly associated with better participation in gastric cancer screening programs (aOR, 5.26; 95% CI: 4.35-6.35). CONCLUSION: Targeted interventions for vulnerable populations and public campaigns about preventive medical evaluation are needed to increase gastric cancer screening participation and reduce gastric cancer mortality.
