Factors associated with intention to receive colonoscopy among community residents in a town of Shanghai: Based on health belief model

  • Objective To identify the factors associated with residents' acceptance of colonoscopy based on health belief model (HBM).

    Methods The study was conducted in community residents in a town of Shanghai in May 2015. We selected 200 participants who accepted colonoscopy (colonoscopy group) and 200 participants who rejected (non-colonoscopy group) after being informed of positive primary screening result of colorectal cancer by convenience sampling, and asked them to complete a questionnaire survey on health belief. The two groups were measured for the differences by t test in variables pertinent to HBM, including perceived susceptibility, severity, benefits, barriers, and cues to action.

    Results A total of 395 residents completed the questionnaire, among whom 199 accepted colonoscopy and 196 rejected. The total scores of HBM were 0.66±0.12 for the colonoscopy group and 0.55±0.14 for the non-colonoscopy group, respectively (P < 0.001). The scores of the five dimensions of HMB in the colonoscopy group were also higher than those in the non-colonoscopy group (Ps < 0.05). Individuals in the colonoscopy group had higher perception levels than those in the non-colonoscopy group in the susceptibility dimension that increased colorectal cancer incidence was associated with higher age and in the benefit dimension that colorectal cancer screening reduced incidence and mortality, improved treatment, and understand self health condition (Ps < 0.001). Suggestions from physicians and supports from family and friends were also important cues to action for residents' acceptance of colonoscopy, with OR (95% CI) of 4.25 (2.05-8.84) and 9.08 (4.19-19.68), respectively, for the colonoscopy group versus the noncolonoscopy group. While for the non-colonoscopy group, they believed less possibility of curing colorectal cancer and had little time for colonoscopy. In the logistic regression analysis, the dimension of benefits had the greatest contribution to the modelOR(95% CI), 44.37 (8.83-222.96), followed by cues to action9.36 (3.36-26.05) and barriers7.00 (2.45-20.03).

    Conclusion The non-colonoscopy group shows insufficient perceived susceptibility, perceived benefits, and social support. Negative attitude towards treatment and prognosis of colorectal cancer and the lack of time for colonoscopy are important barriers to accept colonoscopy.
