Association between the Persistence of Obesity and the Risk of Gastric Cancer: A Nationwide Population-Based Study.

ABSTRACT:

Purpose

There remains controversy about relationship between obesity and gastric cancer. We aimed to examine the association using obesity-persistence.

Materials and methods

We analyzed a nationwide population-based cohort which underwent health check-up between 2009 and 2012. Among them, those who had annual examinations during the last 5 years were selected. Gastric cancer risk was compared between those without obesity during the 5 years (never-obesity group) and those with obesity diagnosis during the 5 years (non-persistent obesity group; persistent obesity group).

Results

Among 2,757,017 individuals, 13,441 developed gastric cancer after median 6.78 years of follow-up. Gastric cancer risk was the highest in persistent obesity group (incidence rate [IR], 0.89/1,0
