We investigated the contribution of supplement use to total nutrient intake, the prevalence of inadequate nutrient intake and the factors associated with supplement use among breast cancer survivors.
A total of 701 Korean breast cancer survivors were included. We calculated the contribution of dietary supplements to total nutrient intake and the proportion of the population below the estimated average requirements (EARs) or exceeding the tolerable upper intake levels (ULs). Stepwise logistic regression was used to identify factors associated with dietary supplement use.
A total of 66.5% of the survivors used dietary supplements, with multivitamins and minerals being the most commonly consumed ones. The per cent contribution of supplement to the total intake was the highest for vitamin C. 28.2%-55.4% of the non-users consumed below the EAR of riboflavin, folate and calcium; 6.1%, 4.9% and 6.5% of the supplement users consumed above the UL of vitamins A and C, and iron, respectively. Supplement users had higher education levels or longer survival time.
66.5% of Korean breast cancer survivors used dietary supplements. A higher education level or prolonged survival time was associated with higher use of dietary supplements.
本研究旨在探讨补充剂的使用对总营养素摄入量的贡献、营养素摄入不足的流行情况以及与补充剂使用相关的因素。
共纳入 701 名韩国乳腺癌幸存者。我们计算了膳食补充剂对总营养素摄入量的贡献以及低于估计平均需求量（EAR）或超过可耐受最高摄入量（UL）的人群比例。逐步逻辑回归用于确定与膳食补充剂使用相关的因素。
共有 66.5%的幸存者使用膳食补充剂，其中最常食用的是多种维生素和矿物质。补充剂对总摄入量的百分比贡献最高的是维生素 C。28.2%-55.4%的非使用者的核黄素、叶酸和钙摄入量低于 EAR；6.1%、4.9%和 6.5%的补充剂使用者的维生素 A 和 C 以及铁摄入量分别超过 UL。补充剂使用者的受教育程度更高或生存时间更长。
66.5%的韩国乳腺癌幸存者使用膳食补充剂。较高的教育水平或较长的生存时间与更高的膳食补充剂使用相关。
