背景：与非土著居民相比，澳大利亚土著居民参与结直肠癌(CRC)筛查的可能性明显较低。本研究旨在找出影响澳大利亚原住民进行粪便潜血检测(FOBT)筛查决定的重要因素。为了减少结直肠癌结果的差异，几乎没有证据来指导干预措施和程序性方法来促进这一人群的筛查。方法：在2009年11月至2010年3月期间，对西澳大利亚土著居民(n=93)进行了访谈者管理的调查，以评估关于结直肠癌和结直肠癌筛查的知识、意识、态度和行为意图。结果：结直肠癌和筛查的知晓率和知识水平很低，尽管两者都与媒体广告的暴露显著相关(p=0.008；p<；0.0001)。近三分之二(63%；58/92)的受访者表示打算参加筛查，而更大比例(84%；77/92)的受访者表示，他们将根据医生的建议进行筛查。多因素Logistic回归分析显示，筛查意向的独立预测因素有较大的自我效能感(OR=19.8，95%CI=5.5~71.8)、癌症筛查参与史(OR=6.8，95%CI=2.0~23.3)和年龄>45岁(OR=4.5，95%CI=1.2~16.5)。结直肠癌知识得分较高(中与低：OR=9.9，95%CI=2.4-41.3；高与低：13.6，95%CI=3.4-54.0)和已婚或有事实关系(OR=6.9，95%CI=2.1-22.5)也是结直肠癌筛查意向的预测因素。结论：通过教育和更大力度的推广筛查，提高结直肠癌相关知识和开展FOBT自我筛查试验的信心，具有提高原住民参与结直肠癌筛查的潜力。这些发现应该指导干预措施的发展，以鼓励土著澳大利亚人进行筛查并减少与肠癌相关的死亡。
Background: Indigenous Australians are significantly less likely to participate in colorectal cancer (CRC) screening compared to non-Indigenous people. This study aimed to identify important factors influencing the decision to undertake screening using Faecal Occult Blood Testing (FOBT) among Indigenous Australians. Very little evidence exists to guide interventions and programmatic approaches for facilitating screening uptake in this population in order to reduce the disparity in colorectal cancer outcomes.Methods: Interviewer-administered surveys were carried out with a convenience sample (n = 93) of Indigenous Western Australians between November 2009-March 2010 to assess knowledge, awareness, attitudes and behavioural intent in regard to CRC and CRC screening.Results: Awareness and knowledge of CRC and screening were low, although both were significantly associated with exposure to media advertising (p = 0.008; p < 0.0001). Nearly two-thirds (63%; 58/92) of respondents reported intending to participate in screening, while a greater proportion (84%; 77/92) said they would participate on a doctor's recommendation. Multivariate analysis with logistic regression demonstrated that independent predictors of screening intention were, greater perceived self-efficacy (OR = 19.8, 95% CI = 5.5-71.8), a history of cancer screening participation (OR = 6.8, 95% CI = 2.0-23.3) and being aged 45 years or more (OR = 4.5, 95% CI = 1.2-16.5). A higher CRC knowledge score (medium vs. low: OR = 9.9, 95% CI = 2.4-41.3; high vs. low: 13.6, 95% CI = 3.4-54.0) and being married or in a de-facto relationship (OR = 6.9, 95% CI = 2.1-22.5) were also identified as predictors of intention to screen with FOBT.Conclusions: Improving CRC related knowledge and confidence to carry out the FOBT self-screening test through education and greater promotion of screening has the potential to enhance Indigenous participation in CRC screening. These findings should guide the development of interventions to encourage screening uptake and reduce bowel cancer related deaths among Indigenous Australians.
