Abstract：
BACKGROUND: Cancer-related incidence and mortality rates are rapidly increasing worldwide. However, no studies have examined the effect of cancer as a single factor on the use of traditional, complementary, and alternative medicine (T&CAM). We aimed to determine the effect of cancer occurrence on T&CAM utilization using Korea Health Panel (KHP) data.
METHODS: We analyzed longitudinal data (49,380 observations) derived from 12,975 Korean adult participants with complete KHP data from 2011 to 2014 and 2016, and divided them into two groups based on cancer diagnosis. A panel multinomial logit model was used to assess whether the participants used T&CAM or conventional medicine or both in outpatient settings. Additionally, a negative binomial regression model was used to examine the effect of cancer on the number of outpatient visits for T&CAM.
RESULTS: In total, 25.54% of the study participants in the cancer group used T&CAM, which was higher than that in the non-cancer group (18.37%, p < 0.0001). A panel multinomial logistic regression analysis using KHP data showed that cancer occurrence was significantly more likely to be associated with \'Using both Korean medicine and conventional medicine\' (Coef. = 0.80, p = 0.017) and \'Not using Korean medicine but using conventional medicine\' (Coef. = 0.85, p = 0.008) than \'Not using Korean medicine and conventional medicine.\' A panel negative binomial regression showed a significant effect of cancer on increasing the number of T&CAM outpatient visits (Coef. = 0.11, p = 0.040).
CONCLUSIONS: Our findings showed that cancer occurrence within an individual led to the simultaneous use of conventional medicine and T&CAM. In addition, the occurrence of cancer significantly increased the number of T&CAM outpatient visits among participants already using T&CAM. It was also found that T&CAM has been utilized more often by the most vulnerable people, such as medical beneficiaries and those with a low level of education.

摘要：
背景：癌症相关的发病率和死亡率在全球范围内迅速增加。然而,没有研究检查癌症作为单一因素对使用传统药物的影响，互补,和替代医学(T&CAM)。我们旨在使用韩国卫生小组（KHP）数据确定癌症发生对T和CAM利用率的影响。
方法：我们分析了从2011年至2014年和2016年具有完整KHP数据的12,975名韩国成年参与者获得的纵向数据（49,380个观察值），并根据癌症诊断将其分为两组。小组多项logit模型用于评估参与者在门诊环境中是否使用T＆CAM或传统医学或两者。此外,我们使用负二项回归模型来检验癌症对T&CAM门诊就诊次数的影响.
结果：总计，癌症组中25.54%的研究参与者使用了T&CAM，高于非癌症组(18.37%，p<0.0001)。使用KHP数据的面板多项逻辑回归分析显示，癌症的发生与“同时使用韩国医学和传统医学”（Coef。=0.80，p=0.017）和\'不使用韩国药物而是使用传统医学\'（Coef。=0.85，p=0.008）比\'不使用韩国医学和传统医学。\'一组阴性二项回归显示，癌症对增加T＆CAM门诊就诊次数具有显着影响（Coef。=0.11，p=0.040）。
结论：我们的研究结果表明，个体内部的癌症发生导致同时使用常规药物和T&CAM。此外,在已经使用T&CAM的参与者中,癌症的发生显著增加了T&CAM门诊就诊的次数.还发现，最脆弱的人更经常使用T和CAM，例如医疗受益人和受教育程度低的人。
