The knowledge of colorectal cancer symptoms and risk factors among 10,078 screening participants: are high risk individuals more knowledgeable?

<h4>Objectives</h4>We tested the a priori hypothesis that self-perceived and real presences of risks for colorectal cancer (CRC) are associated with better knowledge of the symptoms and risk factors for CRC, respectively.<h4>Methods</h4>One territory-wide invitation for free...

They completed survey items on self-perceived and real presences of risks for CRC (advanced age, male gender, positive family history and smoking) as predictors, and knowledge of CRC symptoms and risk factors as outcome measures, respectively. Their associations were evaluated by binary logistic regression analyses.<h4>Results</h4>From 10,078 eligible participants (average age 59 years), the mean knowledge scores for symptoms and risk factors were 3.23 and 4.06, respectively (both score range 0-9). Male gender (adjusted odds ratio [AOR] = 1.34, 95% C.I. 1.20-1.50, p<0.01), self-perception as not having any risks for CRC (AOR = 1.12, 95% C.I. 1.01-1.24, p = 0.033) or uncertainty about having risks (AOR = 1.94, 95% C.I. 1.55-2.43, p<0.001), smoking (AOR 1.38, 95% C.I. 1.11-1.72, p = 0.004), and the absence of family history (AOR 0.61 to 0.78 for those with positive family history, p<0.001) were associated with poorer knowledge scores (≤ 4) of CRC symptoms. These factors remained significant for knowledge of risk factors.<h4>Conclusions</h4>Male and smokers were more likely to have poorer knowledge but family history of CRC was associated with better knowledge. Since screening of these higher risk individuals could lead to greater yield of colorectal neoplasm, educational interventions targeted to male smokers were recommended.Martin C S WongHoyee W HiraiArthur K C LukThomas Y T LamJessica Y L ChingSian M GriffithsFrancis K L ChanJoseph J Y SungPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 8, Iss 4, p e60366 (2013)
