title: Relationship between Salt Preference and Gastric Cancer Screening: An Analysis of a Nationwide Survey in Korea.
abstract: OBJECTIVE
  Epidemiological studies have demonstrated an association between excessive salt intake and gastric cancer risk, and this potential risk increases the need for adequate gastric cancer screening in individuals with high salt intake. However, the association between salt intake and gastric cancer screening in the general population has rarely been investigated. We explored the association between salt preference and participation in gastric cancer screening among a nationally representative Korean population.
  
  
  METHODS
  The study population was derived from the Korean National Cancer Screening Survey (KNCSS) 2006-2007, an annual nationwide interview survey investigating cancer screening rates. Of 4,055 individuals who participated in the KNCSS 2006-2007, 3,336 individuals aged over 40 years were included in our analysis. The odds ratio (OR) and 95% confidence interval (CI) were estimated using polytomous logistic regression.
  
  
  RESULTS
  Individuals with higher salt preference were less likely to participate in regular gastric cancer screening. After adjusting for age, sex, monthly household income, education, family history of cancer, and self-rated health status, ORs for undergoing regular gastric cancer screening were 1.00, 0.82 (95% CI, 0.61 to 1.12), 0.74 (95% CI, 0.54 to 1.00), 0.77 (95% CI, 0.56 to 1.05), and 0.38 (95% CI, 0.16 to 0.92) according to the level of salt preference (p for trend=0.048).
  
  
  CONCLUSIONS
  Individuals with higher salt preference showed suboptimal gastric cancer screening adherence compared to those with a lower salt preference. These findings highlight the need for better delivery of educational messages to change risk perceptions regarding gastric cancer screening practice.
