Participation Rate and Related Factors in Colonoscopy Screening Program in First-Degree Relatives of Patients Affected by Colorectal Cancer

Abstract

Background: First-degree relatives (FDRs) of people diagnosed with colorectal cancer (CRC) have a two-to three-fold increased risk of developing disease. Colonoscopy screening test can be effective in prevention and early treatment. Objectives: The purpose of this study was to determine the rate of participation in colonoscopy screening test and related factors in first degree relatives. Methods: 200 FDRs of CRC cases were interviewed by the researchers. A reliable and valid questionnaire about undergoing colonoscopy screening test and barriers was filled via phone. To report qualitative data results, we used percent and proportion. Full (bytotal variables) and final (Forward LR) multiple logistic regression analysis were used to make a model which was executed using spss19. Results: In total, 59% FDRs had undergone colonoscopy screening test to the time of interview. Major reasons for not participating were fear of pain (23%), concerns about complications and test positive result (21.5%), lack of health insurance (21.5%), not believing in the test effectiveness (17%), no need because of healthy feeling (13%), embarrassment (12%) and distrust to service provider skills (10%). Results of multiple logistic regression analysis indicated there is statistical significance between participating colonoscopy screening and variables "not affected with hypertension (95%CI: 0.4 -2.04, OR = 3.7), believe in test effectiveness in FDRs (95%CI: 1.8 -16.9, OR = 5.6), also age of

Colonoscopy Screening Behaviour and Associated Factors Amongst First-Degree Relatives of People with Colorectal Cancer in China: Testing the Health Belief Model Using a Cross-Sectional Design

“…In the present study, no relationship was identified between sociodemographic variables and undergoing colonoscopy. The findings were inconsistent with previous studies, which reported age, education level and insurance as identified predictors for colonoscopy screening [12][13][14][15]. However, the findings were consistent with a study conducted for community-dwelling Chinese older people [31].…”

“…Based on previous studies [12][13][14][15], demographic characteristics, including potential factors associated with CRC screening behaviours-namely, age, gender, marital status, educational level and insurance-were collected. A family history of CRC was also collected.…”

“…Several studies were conducted to examine the factors associated with the participation in CRC screening amongst FDRs of people with CRC, such as barriers to screening, demographic and lifestyle characteristics [12][13][14][15][16]. Demographic characteristics were the most frequently examined factors, with age, education level and insurance as identified predictors to participate in colonoscopy screening [12][13][14][15]. A review conducted by Tan et al summarised eight qualitative studies [16], which reported that important barriers to CRC screening tests include a fear of cancer diagnosis, discomfort, embarrassment, cost of test and accessibility to health care resources and the lack of awareness of the increased risk of disease development.…”

Participation Rate, Risk Factors, and Incidence of Colorectal Cancer in the Screening Program Among the Population Covered by the Health Centers in Arak, Iran

“…results of a systematic review represented the weakness in the CRC screening awareness, attitude, and behavior in Iran (17). Accordingly, evaluating the barriers and facilitators of CRC screening among the populations is regarded as essential due to the low tendency to the cancer screening, as well as the small participation of moderate-risk individuals (17)(18)(19).…”

The Relationship Between Lifestyle and Compliance with Colonoscopy in First-Degree Relatives of Patients with Colorectal Cancer

“…In addition, the incidence rate of colorectal cancer was reported 7.9 in 100000 persons in 2018 and the 5-year survival rate was reported 43% -49% in Iran (5). Available data indicated Iranians at a younger age are more affected than other population and about 43% of CRC patients are under 50 years old (6,7). Some factors such as inflammatory bowel disease history (Crohn's disease, ulcerative colitis), diabetes mellitus, environmental risk factors (including obesity, radiation, present, and past smoking habits), and high consumption of red meat have a major role in colorectal cancer diseases (8,9).…”
