This study aims to quantify trajectories of overall health pre- and post-diagnosis of cancer, trajectories of overall health among cancer-free individuals, and factors affecting overall health status.
Overall health status, derived from self-rated health report, of Atherosclerosis Risk in Communities cohort participants diagnosed with incident cancer [lung (n = 400), breast (n = 522), prostate (n = 615), colorectal (n = 303)], and cancer-free participants (n = 11,634) over 19 years was examined. Overall health was evaluated in two ways: (1) overall health was assessed until death or follow-up year 19 (survivorship model) and (2) same as survivorship model except that a self-rated health value of zero was used for assessments after death to follow-up year 19 (cohort model). Mean overall health at discrete times was used to generate overall health trajectories. Differences in repeated measures of overall health were assessed using linear growth models.
Overall health trajectories declined dramatically within one-year of cancer diagnosis. Lung, breast, and colorectal cancer were associated with a significant decreased overall health score (β) compared to the cancer-free group (survivorship model: lung-7.00, breast-3.97, colorectal-2.12; cohort model: lung-7.63, breast-5.07, colorectal-2.30). Other predictors of decreased overall health score included low education, diabetes, cardiovascular disease, and age.
All incident cancer groups had declines in overall health during the first year post-diagnosis, which could be due to cancer diagnosis or intensive treatments. Targeting factors related to overall health declines could improve health outcomes for cancer patients.
本研究旨在量化癌症诊断前后的总体健康轨迹、无癌个体的总体健康轨迹以及影响总体健康状况的因素。
对社区动脉粥样硬化风险队列研究中被诊断为新发癌症的参与者[肺癌(n = 400)、乳腺癌(n = 522)、前列腺癌(n = 615)、结直肠癌(n = 303)]以及19年间无癌参与者(n = 11,634)的自我健康报告得出的总体健康状况进行了检查。总体健康状况通过两种方式进行评估:(1)评估总体健康状况直至死亡或随访第19年(生存模型);(2)与生存模型相同,但在死亡后至随访第19年的评估中使用自评健康值为零(队列模型)。使用离散时间的平均总体健康状况来生成总体健康轨迹。使用线性增长模型评估总体健康状况重复测量的差异。
癌症诊断后一年内总体健康轨迹急剧下降。与无癌组相比,肺癌、乳腺癌和结直肠癌与总体健康评分显著降低相关(生存模型:肺癌-7.00,乳腺癌-3.97,结直肠癌-2.12;队列模型:肺癌-7.63,乳腺癌-5.07,结直肠癌-2.30)。总体健康评分降低的其他预测因素包括低教育水平、糖尿病、心血管疾病和年龄。
所有新发癌症组在诊断后的第一年总体健康状况均下降,这可能是由于癌症诊断或强化治疗所致。针对与总体健康下降相关的因素可能会改善癌症患者的健康结局。
