To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status we surveyed 169 persons 90 females and 79 males aged 40∼69 years from June 7 to June 14 1997 in Whachon area Kang-Won Do Korea. For this purpose we investigated Helicobacter pylori infec-tion and identified the effect of sex age, smoking alcohol consumption economic status occupation life-style and food intake on Helicobacter phlori infection. Helicobacter pylori status was evaluated using an en-zyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicob-acter pylori infection was present in 66.3% of total subjects namely 67.7% of female and 64.4% of male and its prevalence increased with smoking low education level and low monthly income. Energy total protein calcium and vitamin C intakes in the negative Helicobacgter phlori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the helicobacter pylori negative group than in the positive group.

Helicobacter pylori (H. pylori) infection as a serious problem in both adults and children can induce chronic gastritis, peptic ulcer disease (PUD), and possibly gastric cancer. The aim of the current study was to survey antibiotic resistance and also to determine influence of PPAR$\gamma$ polymorphism in patients with H. pylori infection. During an 11-month-period, 98 H. pylori isolates were collected from 104 biopsy specimens. In vitro susceptibility of H. pylori isolates to 4 antimicrobial agents metronidazole, clarithromycin, amoxicillin and tetracycline were assessed by quantitative method according to European Committee on Antimicrobial Susceptibility Testing (EUCAST) guideline. PPAR$\gamma$ polymorphism was determined using polymerase chain reaction-restriction fragment length polymorphism assay. The frequency of H. pylori infection in our study was 94.2%. In vitro susceptibility data showed that highest level of resistance was related to metronidazole (66.3%), and the majority of H. pylori isolates were highly susceptible to amoxicillin and tetracycline (94.9% and 96.9%, respectively). Genotypic frequencies were 25.5% for CC (Pro12Pro), 40.8% for GC (Pro12Ala) and 33.7% for GG (Ala12Ala). In our study, CG genotype had highest distributions among infected patients with H. pylori. The study suggests that the PPAR-$\gamma$ Pro12Ala polymorphism could be evaluated as a potential genetic marker for susceptibility to gastric cancer in the presence of H. pylori infection.

To examine the relationship between the causal infection of gastric cancer and lifestyle and nutritional status, we surveyed 183 persons, 102 female and 81 male, aged 40 years and over from August to October, 1996, in Chunchon area, Kang Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection in the agricultural Korean adult and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation and lifestyle. Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 64.5% of total subjects, and 63.7% of female, 65.4% of male and its prevalence was increased with age, smoking, low education level, low monthly income, high childbirth. Some nutrients intakes were significantly difference between Helicobacter pylori infection positive(+) group and those negative(-) group. The negative Helicobacter pylori infection group were much more intaked energy, total protein, total fat(p<0.05), animal fat(p<0.05), Iron(p<0.001), vitamin A(p<0.01), vitamin C(p<0.05) than Helicobacter pylori positive infection group. But the calcium intakes were lower than positive(+) group.

Objectives ; The objective of this study was to evaluate the prevalence of atrophic gastritis and intestinal metaplasia according to gender, age and Helicobacter pylori infection in a rural population in Korea. Methods: Between April 2003 and January 2007, 713 subjects (298 men and 415 women, age range: 18-85) among the 2,161 adults who participated in a population-based survey received gastrointestinal endoscopy. All the subjects provided informed consent. Multiple biopsy specimens were evaluated for the presence of atrophic gastritis and intestinal metaplasia. The presence of Helicobacter Pylori was determined using CLO and histology testing. Results ; The age-adjusted prevalence of atrophic gastritis was 42.7% for men and 38.1% for women and the prevalence of intestinal metaplasia was 42.5% for men and 32.7% for women. The prevalence of atrophic gastritis and intestinal metaplasia increased significantly with age for both men and women (p for trend<0.001). The age-adjusted prevalence of Helicobacter pylori was similar for men (59.0%) and women (56.7%). The subjects with Helicobacter pylori infection showed a significantly higher prevalence of intestinal metaplasia (44.3%) compared with that (26.8%) of the noninfected subjects (p<0.001). However, the prevalence of atrophic gastritis was not statistically different between the Helicobacter pylori-infected subjects and the noninfected individuals. Conclusions : Our findings suggest that the prevalence of atrophic gastritis and intestinal metaplasia is higher for a Korean rural population than that for a Western population; this may be related to the high incidence of gastric cancer in Koreans. Especially, the prevalence of intestinal metaplasia was high for the subjects with Helicobacter pylori infection. The multistep process of gastric carcinogenesis and the various factors contributing to each step of this process need to be determined by conducting future follow-up studies.
