한국 유방암 경험자들의 유방암 식사지침 수행 정도와 건강관련 삶의 질의 연관성

Abstract

Objectives: We examined the association between the adherence to dietary guidelines for breastcancer survivors and health-related quality of life in a cross-sectional study of Korean breastcancer survivors. Methods: A total of 157 women aged 21 to 79 years who had been diagnosed with stage I toIII breast cancers according to the American Joint Committee on Cancer (AJCC) and hadbreast cancer surgery at least 6 months before the baseline were included. We used a Koreanversion of the Core 30 (C30) and Breast cancer 23 (BR23) module of the EuropeanOrganization for Research and Treatment Cancer Quality of Life Questionnaire (EORTC-QLQ),both of which have been validated for Koreans. Participants were asked about their adherenceto dietary guidelines for breast cancer survivors, suggested by the Korean breast cancer society,using a 5-point Likert scale. We summed dietary guideline adherence scores for each participantand calculated the least squares means of health-related quality of life according to dietaryguideline adherence scores using the generalized linear model. Results: Breast cancer survivors who had higher adherence to dietary guidelines for breastcancer survivors had lower constipation scores than those with lower adherence (p fortrend=0.01). When we stratified by the stage at diagnosis, this association was limited to thosewho had been diagnosed with stage II or III breast cancers. Also, sexual functioning scoresincreased significantly with increasing adherence scores of dietary guidelines among those withstage II or III breast cancers (p for trend < 0.001). However, among those who had beendiagnosed with stage I, higher scores of dietary guidelines were associated with higher scoresof pain (p for trend=0.03) and breast symptoms (p for trend=0.05). Conclusions: Our study suggested that the health-related quality of life levels of breast cancersurvivors are associated with the adherence to dietary guidelines and may differ by the stage ofthe breast cancer.
