Colorectal cancer (CRC) is the second most common cancer in Malaysia. Awareness of risk factors, symptoms and warning signs of CRC will help in early detection. This paper presents the level of CRC awareness among the urban population in Malaysia.
A cross-sectional study was conducted from November 2015 till December 2016 at three government clinics in the Klang Valley. The validated Bowel Cancer Awareness Measure questionnaire in both English and Malay was used. The mean knowledge scores for the warning signs and risk factors of CRC in different socio-demographic groups were compared using ANOVA in SPSS version 23. Statistical significance was set at p<0.05 and a 95% confidence level.
Of the 426 respondents, 29.1% were unable to recall the warning signs and symptoms of CRC. Average recall was less than two warning signs and symptoms (mean 1.62, SD 1.33). The mean total knowledge score for CRC was 9.91 (SD 4.78), with a mean knowledge scores for warning signs and risk factors at 5.27 (SD 2.74) and 4.64 (SD 2.78), respectively. Respondents with a higher level of education were found to have higher level of knowledge regarding the warning signs of CRC. There was a significant positive association between knowledge score for warning signs and level of confidence in detecting warning signs. Regarding the total knowledge score for CRC, 3.3% of respondents scored zero. For warning signs and risk factors, 8.2% and 8.5% of respondents had zero knowledge scores, respectively.
Generally, awareness of CRC is poor among the urban population of Klang Valley. Greater education and more confidence in detecting warning signs are significantly associated with better knowledge of warning signs. CRC awareness programs should be increased to improve awareness.
结直肠癌（CRC）是马来西亚第二常见的癌症。了解CRC的风险因素、症状和警示信号将有助于早期发现。本文介绍了马来西亚城市人口对CRC的认知水平。
2015年11月至2016年12月在巴生谷的三家政府诊所进行了一项横断面研究。使用了经过验证的英文和马来文版的结直肠癌认知测量问卷。在SPSS 23版本中，使用方差分析比较不同社会人口学群体中CRC警示信号和风险因素的平均知识得分。统计学显著性设定为p<0.05和95%置信水平。
在426名受访者中，29.1%无法回忆起CRC的警示信号和症状。平均回忆起的警示信号和症状少于两个（均值1.62，标准差1.33）。CRC的平均总知识得分为9.91（标准差4.78），警示信号和风险因素的平均知识得分分别为5.27（标准差2.74）和4.64（标准差2.78）。发现教育水平较高的受访者对CRC警示信号的了解程度更高。警示信号的知识得分与检测警示信号的信心水平之间存在显著正相关。关于CRC的总知识得分，3.3%的受访者得分为零。对于警示信号和风险因素，分别有8.2%和8.5%的受访者知识得分为零。
总体而言，巴生谷城市人口对CRC的认知较差。更高的教育程度和检测警示信号的更强信心与对警示信号的更好了解显著相关。应增加CRC认知项目以提高认知。
