DNA methylation of CDH13 is associated with gene repression and carcinogenesis. We determined the relation of dietary fat and sex with CDH13 cg02263260 methylation in Taiwanese adults. Data of 870 eligible participants (430 men and 440 women) aged 30-70 years were obtained from the Taiwan Biobank (TWB) database. The association of dietary fat and sex with CDH13 cg02263260 methylation was determined using multiple linear regression. The association between sex and cg02263260 methylation was significant: beta‐coefficient (β) = 0.00532; 95% confidence interval (CI) = 0.00195–0.00868. Moreover, the interaction between sex and dietary fat on cg02263260 methylation was significant (P‐value = 0.0145). After stratification by sex, the association of dietary fat with cg02263260 methylation was significant only in women. Specifically, high dietary fat was positively associated with cg02263260 methylation in women (β = 0.00597; 95% CI = 0.00061–0.01133) and the test for trend was significant (P‐value = 0.0283). High fat intake was significantly associated with higher cg02263260 methylation in women and the test for trend was significant. These findings suggest that the association of fat intake and CDH13 cg02263260 might vary by sex and CDH13 cg02263260 methylation levels in women might increase as fat intake increases.表觀遺傳學DNA甲基化鈣粘蛋白cg02263260性別高脂肪飲食。EpigeneticsDNA methylationcadherinsexfat intake.thesis
