ABSTRACT
OBJECTIVE: Refrigeration of food has been shown to mitigate environmental and dietary risk factors important in the pathogenesis of gastric cancer. Globally, the incidence of gastric cancer has decreased. This study aims to determine the relationship between refrigerator ownership and gastric cancer.
METHODS: Gastric cancer data were obtained from the Global Burden of Disease study, and refrigerator ownership data were sourced from GlobalDataLab. Countries were excluded from the analysis if they lacked refrigerator ownership data for more than 10 years or had over 80% ownership at the start of data collection. The relationship between the two variables was assessed using Spearman’s rank correlation coefficient.
RESULT: Countries were screened using the inclusion criteria, and 85 countries from five continents were included in the study. Seventy-three countries demonstrated a negative correlation between refrigerator ownership and gastric cancer among their male populations, and 55 countries showed comparable results among their female populations. Thirteen countries exhibited a positive correlation between the two variables.
CONCLUSION: Increasing refrigerator ownership appears to be associated with decreasing gastric cancer rates. Further research is needed to identify the specific risk factors involved in gastric cancer pathogenesis in the 13 countries where this association was not observed.
