Background/Objectives: With improved technology and cancer treatments, the number of cancer survivors is growing. However, many cancer survivors experience long-term effects of cancer and its treatment, leading to a high health burden and poorer quality of life (QoL). A growing body of literature has explored the relationship between sociodemographic variables and QoL among cancer patients, although findings remain mixed. This study aims to assess the impact of social factors—role functioning, social functioning and social support—on the QoL of Icelandic cancer survivors diagnosed between 2015 and 2019, stratified by gender and cancer type (breast, prostate and colorectal cancer). Method: This study is a secondary analysis study, using data from a cross-sectional study conducted by the Icelandic Cancer Society in 2020–2021. In total, 1200 cancer survivors participated. Results: Multiple regression showed that less depressive symptoms, higher role and social functioning, better instrumental social support, higher educational attainment and income, less financial difficulties and lower age were significantly associated with higher QoL among participants. Conclusions: cancer survivors’ global health status/QoL is highly influenced by role functioning and depression symptoms, while other predictive factors, including social functioning, social support, education and income, vary by gender and cancer type.
背景/目的：随着医疗技术和癌症治疗手段的进步，癌症幸存者数量持续增长。然而，许多幸存者仍面临癌症及其治疗带来的长期影响，导致较高的健康负担和生活质量下降。现有研究虽已探讨社会人口学变量与癌症患者生活质量之间的关系，但结论尚不一致。本研究旨在评估社会因素——角色功能、社会功能与社会支持——对2015至2019年间确诊的冰岛癌症幸存者生活质量的影响，并按性别及癌症类型（乳腺癌、前列腺癌和结直肠癌）进行分层分析。方法：本研究为二次分析研究，采用冰岛癌症协会于2020至2021年开展的横断面调查数据，共纳入1200名癌症幸存者。结果：多元回归分析显示，抑郁症状较轻、角色与社会功能较好、工具性社会支持较高、教育程度与收入水平较高、经济困难较少及年龄较低，均与参与者更高的生活质量显著相关。结论：癌症幸存者的整体健康状况/生活质量主要受角色功能和抑郁症状影响，而社会功能、社会支持、教育程度及收入等其他预测因素的作用则因性别和癌症类型存在差异。
