Abstract

Objectives Thyroid cancer is the most common cancer among Korean women. Studies suggest that the incidenceof thyroid cancer might be associated with overdiagnosisresulting from thyroid cancer screening. The objective ofthis study was to identify the determinants of participationin thyroid cancer screening in Korean women.Methods Data were obtained from the 2016 Korean Studyof Women’s Health-Related Issues, a nationwide crosssectionalsurvey of women according to the reproductivelife cycle. A total of 8697 cancer-free women of agesbetween 20 and 79 years were included for analysis.Multivariable logistic regression analysis was appliedto analyse factors associated with adherence to thyroidcancer screening based on Andersen’s health behaviouralmodel.Results Over the last 2 years, the rate of thyroid cancerscreening was 39.2%. In multivariable models, older age,higher household income, high school education level andhigher perceived risk of cancer were positively associatedwith thyroid cancer screening participation. Moreover,women who underwent cervical cancer screening(adjusted OR [aOR] 3.67; 95% CI 2.90 to 4.64) and breastcancer screening (aOR 10.91; 95% CI 8.41 to 14.14) hadhigher odds of attending thyroid cancer screening thanwomen who did not attend cancer screening.Conclusions These findings highlight the need to increaseawareness of different recommendations on screeningfor various cancers to improve cost-effectiveness and toprevent unnecessary treatments.
