Previous studies have shown the inverse association between diet quality and cancer mortality. Therefore, this study aims to discover the factors that affect diet quality among cancer survivors. We analyzed the 12 years of Korea National Health and Nutrition Examination Survey data, which included 2,756 cancer survivors. We analyzed 30 factors considered to be associated with diet quality. As a result, factors related to diet quality differed between males and females. A male cancer survivor who is aged < 65, living with members of the household, living without a spouse, having a lower household income, a blue-collar worker, a beneficiary of national basic livelihood, sleeping > 9 hours a day, unaware of a nutritional fact label, insecure in food, non-user of dietary supplements, not on diet therapy, limited in activity, perceiving stress, and obese, are more likely to have lower Korean Healthy Eating Index (KHEI) scores. On the other hand, a female cancer survivor who is aged < 65, a pink-collar worker, inexperienced in nutritional education, non-users of dietary supplements, obese, and has a lower education level, and cervical or stomach cancer is prone to have lower KHEI scores. In conclusion, factors associated with diet quality among cancer survivors are sex-specific. Therefore, sex-specific factors should be considered when identifying and intervening in cancer survivors at risk for lower diet quality scores.
