Relationship between health information literacy and health promoting lifestyle among first-degree relatives of patients with colorectal cancer in China: the mediating effect of health belief. Front Public Health 2023; 11:1178848. [PMID: 37522002 PMCID: PMC10382199 DOI: 10.3389/fpubh.2023.1178848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 06/27/2023] [Indexed: 08/01/2023] Open
Abstract
Background History of first-degree relatives with colorectal cancer is one of the most important and common risk factors for colorectal cancer in China. Most chronic diseases, such as malignancies, are preventable by adopting health-promoting behaviors and other approaches. However, the relationships among factors affecting the health-promoting lifestyles of first-degree relatives with colorectal cancer have not been sufficiently studied. This study aimed to test the mediation effects of Health belief in the relationship between health-promoting lifestyle and health information literacy among first-degree relatives with colorectal cancer. Methods A cross-sectional descriptive design was conducted using convenience sampling of 856 first-degree relatives of CRC patients attending three tertiary care hospitals in Nanchong and Deyang of China from December 2020 to December 2022. Questionnaires were used to collect data on the participants' demographic information, the colorectal cancer health beliefs, the health promotion lifestyle, and the health information literacy. Data were analyzed with descriptive statistics, one-way ANOVA, Pearson's correlation coefficients, and mediation analysis using SPSS 25.0 program and its macro-program PROCESS. Results The findings indicated health information literacy was less, health belief was at the medium level, and performance of health promotion behavior was average for first-degree relatives of colorectal cancer. Whereas first-degree relatives of colorectal cancer health-promotion lifestyle had a positive correlation with health beliefs (r = 0.376, p < 0.01) and health information literacy (r = 0.533, p < 0.01), health beliefs had a positive correlation with health information literacy (r = 0.337, p < 0.01). Health beliefs mediated the positive effect of health information literacy on health-promoting lifestyles (β =0.420, 95% CI, 0.288-0.581), and indirect effects accounted for 14.0% of the total effect. Conclusion Health information literacy and health beliefs are key factors associated with a health-promoting lifestyle among first-degree relatives with colorectal cancer. These factors have direct and indirect effects on each other and on health-promoting lifestyles. To enhance health-promoting lifestyles among first-degree relatives with colorectal cancer, interventions that strengthen health beliefs and provide health information literacy should be developed.

Geographic, Demographic, and Socioeconomic Disparities and Factors Associated With Cancer Literacy in China: National Cross-sectional Study. JMIR Public Health Surveill 2023; 9:e43541. [PMID: 36800218 PMCID: PMC9985002 DOI: 10.2196/43541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 12/08/2022] [Accepted: 12/09/2022] [Indexed: 02/18/2023] Open
Abstract
BACKGROUND Cancer literacy is associated with several health-related behaviors and outcomes. However, there is still a lack of nationwide surveys for cancer literacy in China. OBJECTIVE This study aims to evaluate cancer literacy in China, explore disparities, and provide scientific evidence for policy makers. METHODS A cross-sectional survey was conducted in mainland China in 2021 using the multistage probability proportional to the size sampling method. Both the reliability and validity of the questionnaire were evaluated. The awareness levels were adjusted by sampling weights and nonrepresentativeness weights to match the actual population distributions. The Rao-Scott adjusted chi-square test was applied to test geographic, demographic, and socioeconomic disparities. A generalized linear model was used to explore potential factors. RESULTS A total of 80,281 participants aged 15-74 years were finally enrolled from 21 provinces, with an overall response rate of 89.32%. The national rate of cancer literacy was 70.05% (95% CI 69.52%-70.58%). The rates were highest regarding knowledge of cancer management (74.96%, 95% CI 74.36%-75.56%) but were lowest regarding basic knowledge of cancer (66.77%, 95% CI 66.22%-67.33%). Cancer literacy was highest in East China (72.65%, 95% CI 71.82%-73.49%), Central China (71.73%, 95% CI 70.65%-72.81%), and North China (70.73%, 95% CI 68.68%-72.78%), followed by Northeast (65.38%, 95% CI 64.54%-66.22%) and South China (63.21%, 95% CI 61.84%-64.58%), whereas Southwest (59.00%, 95% CI 58.11%-59.89%) and Northwest China (57.09%, 95% CI 55.79%-58.38%) showed a need for improvement. Demographic and socioeconomic disparities were also observed. Urban dwellers, the Han ethnic group, and population with higher education level or household income were associated with prior knowledge. The questionnaire showed generally good internal and external reliability and validity. CONCLUSIONS It remains important for China to regularly monitor levels of cancer literacy, narrow disparities, and strengthen health education for dimensions with poor performance and for individuals with limited knowledge to move closer to the goal of Healthy China 2030.

Abstract
Purpose One of the most common cancers in Asia is colorectal cancer (CRC). Early diagnosis and timely treatment are necessary for preventing complications and advanced stages of the disease. It is important to evaluate barriers and facilitators of screening in different countries. This systematic review aimed to identify the barriers and facilitators of CRC screening in Asia. Methods In this systematic review, for identifying barriers and facilitators of CRC screening, a comprehensive search was conducted in PubMed, Web of Science and Scopus in 12 December 2020. Combination keywords such as colorectal cancer, screening, sigmoidoscopy, colonoscopy, faecal occult blood test, barriers, facilitators and the names of each Asian country were used for searching. Full text original studies in English language were accepted in the review. Results In total, 36 articles were included in the review. Barriers and facilitators were evaluated. The most common reported barriers were lack of knowledge, fear of result, fear of procedure, fear of pain, lack of awareness, high cost and lack of gastrointestinal symptoms. The most frequent facilitators were having knowledge and awareness of CRC screening, perceived risk and severity, family history of cancer and physician recommendation. Conclusion For promoting success in CRC screening programmes, knowing what the barriers and facilitators are is necessary. Awareness and various personal, professional and social factors have been shown to be the major barriers toward CRC screening in most Asian countries.

Factors Associated with Knowledge, Attitudes, and Practice towards Colorectal Cancer and Its Screening among People Aged 50-75 Years. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18084100. [PMID: 33924546 PMCID: PMC8070487 DOI: 10.3390/ijerph18084100] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 04/06/2021] [Accepted: 04/08/2021] [Indexed: 11/23/2022]
Abstract
Background: Colorectal cancer (CRC) screening is effective for early detection of CRC, particularly for males aged 50 or above. However, the rate of participation in the screening program is still low. This study was to examine knowledge, attitudes, and practice toward CRC and its screening and explored their associated factors. Methods: A descriptive cross-sectional study was conducted in a convenience sample of adults aged 50–75 years without cognitive problems, who were recruited at multi-elderly centers in Hong Kong. A questionnaire was used to measure knowledge, attitudes, and practice (KAP) towards CRC and its screening. Results: The total of 300 Chinese people included 147 (49.0%) males with a mean age of 58.72 (SD 6.91) years old. This study population had good knowledge and practice, as well as very good attitudes toward CRC and its screening. The multivariate regression results showed that receiving insurance coverage was the most significant factor positively associated with knowledge, attitudes, and practice. Other than this, lower educational level had significant negative association with knowledge and practice. Having self-sufficient financial support and receiving screening program information had positive associations with knowledge. Conclusion: People who are receiving insurance coverage have better KAP towards CRC and its screening. This indicates that they can receive adequate information about the screening procedure from their insurance agents and receive financial support under their insurance coverage. Therefore, they are more willing to participate in the screening program. Other factors, including having good self-sufficient financial support and receiving adequate information about CRC and its screening, significantly enhance knowledge. Based on the relationships among KAP, knowledge enhancement can improve attitude and practice in participating in the CRC screening program. Those who attained lower education should receive more attention. In this sense, adequate financial support from health insurance or subsidies from the government can increase an individual’s willingness to participate in the CRC screening, particularly those at a low socioeconomic level. Educational programs should be promoted to enhance knowledge about CRC and its screening, especially to those who attained lower education levels.

Abstract
OBJECTIVE This study aimed to evaluate how the knowledge and perception towards colorectal cancer (CRC) screening had been changed in a large population, and identified factors associated with its participation based on factors pertinent to the Health Belief Model (HBM). METHODS Data from 3600 screening participants and 3600 non-participants were collected through a telephone survey via simple random sampling of telephone numbers in a territory-wide directory from December 2016 to November 2018. Sociodemographic factors; the enabling factors of screening as well as the barriers of screening were collected. The changes in these factors were evaluated by Pearson's chi-square trend test. A logistic regression model was constructed to identify the association between the above factors and CRC screening participation. RESULTS The knowledge level (67.9% to 85.4%, p < 0.001), perceived severity of having CRC (37.7%-42.8%, p < 0.01), perceived benefits of screening (54.9%-72.1%, p < 0.001), and reductions in barriers (14.1%-5.1%, p < 0.001) of CRC screening significantly improved among the non-users. Subjects with older age (adjusted odds ratio (AOR): 2.01, p < 0.001), higher knowledge level of screening methods (AOR: 6.68, p < 0.001), greater perceived severity (AOR: 2.04, p < 0.001) and coverage of insurance (AOR: 1.22, p < 0.01) were more likely to participate. In contrast, more affluent subjects (AOR: 0.69, p < 0.001), female individuals (AOR: 0.63, p < 0.001), higher level of perceived psychological (AOR: 0.54, p < 0.001) and access barriers (AOR: 0.55, p < 0.001) were associated with poorer participation. CONCLUSION These findings demonstrated a substantial increase in the enabling factors of CRC screening, including knowledge, perceived severity and perceived benefits. The study also identified the target groups such as younger individuals, females and more affluent people among whom more intensive educational initiatives are needed to enhance their participation.

Abstract
Colorectal cancer screening saves lives and is cost-effective. It allows early detection of the pathology, and enables earlier medical intervention. Despite clinical practice guidelines promoting screening for average risk individuals, uptake remains suboptimal in many populations. Few studies have examined how sociobehavioural factors influence screening uptake in the context of behaviour change theories such as the health belief model. This systematic review therefore examines how the health belief model’s constructs are associated with colorectal cancer screening. Four databases were systematically searched from inception to September 2019. Quantitative observational studies that used the health belief model to examine colorectal screening history, intention or behaviour were included. A total of 30 studies met the criteria for review; all were of cross-sectional design. Perceived susceptibility, benefits and cues to action were directly associated with screening history or intention. Perceived barriers inversely associated with screening history or intention. The studies included also found other modifying factors including sociodemographic and cultural norms. Self-report of screening history, intention or behaviour, convenience sampling and lack of temporality among factors were common limitations across studies. The health belief model’s associations with colorectal cancer screening uptake was consistent with preventive health behaviours in general. Future studies should examine how theory-based behavioural interventions can be tailored to account for the influence of socioecological factors.

Abstract
Screening can help early detection of colorectal cancer (CRC) in the general population. However, colonoscopy compliance in screening program is low in China. The study aimed to identify factors associated with colonoscopy compliance based on Health Belief Model (HBM). An investigation was conducted in Huangpu District, Shanghai in 2015. High-risk individuals of CRC received an in-person interview with physicians to fill out a questionnaire. The questionnaires assessing predictors of colonoscopy compliance were collected, and status of colonoscopy participation was determined. Univariate and multiple logistic regression analyses were conducted. Among 2,568 high-risk population (20.68%), 531 subjects underwent colonoscopy. Participants with both risk assessment and fecal immunochemical test positive were most likely to undergo colonoscopy. Based on HBM, colonoscopy compliance was positively associated with higher perceived severity (odds ratio [OR] = 1.05, 95% confidence interval [CI] = [1.00, 1.10]). Higher perceived barriers (OR = 0.97, 95% CI = [0.94, 0.99]), without prior colonoscopy (OR = 0.35, 95% CI = [0.26, 0.47]), not knowing anyone who underwent colonoscopy before (OR = 0.74, 95% CI = [0.58, 0.96]), without health-care provider recommendation on colonoscopy (OR = 0.58, 95% CI = [0.44, 0.77]), and without psychosocial support from someone for colonoscopy (OR = 0.27, 95% CI = [0.21, 0.35]) were shown to be associated with colonoscopy noncompliance. The colonoscopy compliance was low in this CRC screening program in Shanghai, China. The influencing factors were positive results in primary screening, perceived severity, perceived barriers, personal or others' experiences in colonoscopy, health-care provider recommendation, and psychosocial supports. Effective education campaign and facilitated communication between health-care providers and high-risk population were suggested in the future interventions.

Abstract
Background Colorectal cancer (CRC) is one of the common cancers affecting both genders. Although the incidence of CRC is low in India there has been an increase in the past few decades. Objective To assess the awareness regarding colorectal cancer and its screening among medical students and interns. Methods This cross-sectional study was conducted among 290 participants (final year medical students and interns) from Kasturba Medical College, Mangalore. A pretested semistructured questionnaire was used to collect information. Data was analyzed using SPSS 17.0. Results Majority of participants had satisfactory knowledge regarding CRC. 38% of them scored excellently, 64.8% had good knowledge, and 5.2% scored poorly. Knowledge regarding CRC symptoms was good (95%). 92% of the participants were aware of risk factors of CRC. Only 49% of the participants identified FOBT as a screening tool and 30.7% participants knew that 50 years is the recommended age to begin CRC screening. Interns and international students had better knowledge than final year medical students and Indian students and this was found to be statistically significant. Conclusion There is a need to improve participant's knowledge regarding CRC screening although majority of them are aware of CRC symptoms and risk factors.

Abstract
Background: In Guangzhou, China, colorectal cancer (CRC) is the second most commonly diagnosed cancer.
The government initiated a CRC screening program in 2015, and investigating the knowledge, attitudes, and practices
toward CRC would help facilitate the participation of the program. Methods: A cross-sectional survey was conducted
from October 2014 to September 2015. Questionnaires were passed out with a cluster sample in 15 randomly selected
primary schools of Guangzhou China, and one of each student’s family members aged between 20 to 65 years old
were included. Results: A total of 6839 questionnaires were obtained and the successful response rate was 78.5%.
The majority (88.3%) of them were under 46 years old and female subjects accounted for 65.8%. Over 80% of the
respondents knew that CRC was able to be cured by early diagnosis and treatment and that tobacco use, alcohol abuse,
and dietary without enough fruits or vegetables may increase the risk of CRC, although a few knowledge scores were
relatively low, such as physical exercise as a protective factor and bowel habits change as a symptom suggestive of
CRC. In contrast, only 52.2% of the subjects were sure to participate in a future CRC screening provided by local
government. We further found that the higher level of knowledge about CRC risk and positive cancer preventive attitude
and practice were associated with higher education level, female gender, and positive family history. Conclusion: These
results suggested that the priority may be laid on improving the conversion from knowledge to practice to implement
screening program in Guangzhou, while efforts should also be made to improve public awareness about CRC.

Abstract
Introduction: This study aimed to investigate the factors associated with FOBT screening for colorectal cancer based on the components of Health Belief Model and social support in Fasa City, Fars Province, Iran. Materials and Methods: This was a cross-sectional study carried out on 240 subjects in people of Fasa city who had 50 years old and above. The subjects in this study were assigned to two groups of 120 patients. The first group included people over 50 years, who referred to the diagnostic laboratories for doing FOBT, but the second group included people aged 50 years and above who did not refer to a laboratory for doing FOBT and were assessed by questionnaires at home. Data were collected through a questionnaire based on health belief model and perceived social support. Results: The referring group included 61.3 percent women and 38.7 percent men, with a mean age of 65.24 ± 8.01. The non-referring group included 59.7 percent women and 40.3 percent men, with a mean age of 64.21 ±7.53 (p=0.24). In the referring group, 64.2 percent had undergone FOBT in the past year, while in the non-referring group only 12.72percent had done so (p=0.001). The results showed that the referring group obtained higher scores on awareness about CRC and ways to prevent it, and on HBM Model constructs, and social support compared to the non-referring group (p<0.001). In addition, the referring group reported significantly lower Perceived Barriers compared to the non-referring group (p<0.001). Conclusion: The results showed significant differences between the two groups in terms of HBM components and perceived social support for doing FOBT. Therefore, theory-based educational interventions can be used to increase individuals’ Perceived Severity, Perceived Susceptibility, and Perceived Benefits and reduce their Perceived Barriers in order to empower and encourage people to perform FOBT.

Abstract
Introduction: This study aims to identify the barriers to adopting faecal occult blood test (FOBT) and colonoscopy as colorectal cancer (CRC) screening methods among the eligible target population of Singapore. Materials and methods: This study was previously part of a randomised controlled trial reported elsewhere. Data was collected from Singapore residents aged 50 and above, via a household sample survey. The study recruited subjects who were aware of CRC screening methods, and interviewed them about the barriers to screening that they faced. Collected results on barriers to each screening method were analysed separately. Results: Out of the 343 subjects, 85 (24.8%) recruited knew about FOBT and/or colonoscopy. Most of the respondents (48.9%) cited not having symptoms as the reason for not using the FOBT. This is followed by inconvenience (31.1%), not having any family history of colon cancer (28.9%), lack of time (28.9%) and lack of reminders/recommendation (28.9%). Of the respondents who indicated not choosing colonoscopy as a screening method, more than one-half (54.8%) identified not having any symptoms as the main barrier for them, followed by not having any family history (38.7%) and having a healthy/low-risk lifestyle (29.0%). There was no difference between the reported barriers to each of the screening methods and the respondents’ dwelling types. Conclusions: Lack of knowledge, particularly the misconceptions of not having symptoms and being healthy, were identified as the main barriers to FOBT and colonoscopy as screening methods. Interventions to increase the uptake of CRC screening in this population should be tailored to address this misconception.

Abstract
BACKGROUND Older adults are more susceptible to colorectal cancer (CRC). Psychosocial constructs in the Health Belief Model are targets for interventional studies. No tool to measure these beliefs of older Chinese people has been validated. OBJECTIVE The present study aimed to examine the preliminary psychometric properties of the Chinese version of the Colorectal Cancer Perceptions Scale (CRCPS). METHODS The CRCPS was translated to Chinese language, validated by an expert panel, and tested. Interviewer-administered surveys were carried out with a convenience sample of 219 community-dwelling Chinese adults 60 years or older and were included in the analysis. RESULTS Six factors were retained, with items on susceptibility and benefits remaining as designed, whereas those on severity formed 2 factors, labeled severity-fear and severity-life impact, and those on barriers again formed 2 factors, labeled psychological barriers and knowledge barriers. Cronbach's α values ranged from .74 to .88, and test-retest reliability correlations ranged from .38 for psychological barriers to .69 for knowledge barriers. Respondents who had undergone CRC screening had significantly lower mean scores on severity-fear, severity-life impact, psychological barriers, and knowledge barriers compared with those who had not. CONCLUSIONS The results provide preliminary support for the reliability and validity of the Chinese version of the CRCPS. Further psychometric testing is recommended. IMPLICATIONS FOR PRACTICE The survey provides a useful tool to assess CRC health beliefs, which interventions should address to improve screening rates among older Chinese adults.

Abstract
Colorectal cancer (CRC) is a major health problem in Asia. It has been reported that the Chinese are more susceptible to CRC than many other ethnic groups. Screening for CRC is a cost-effective prevention and control strategy; however, the screening rates among the Chinese are sub-optimal. We conducted a review to identify the factors associated with CRC screening participation among Chinese people. Twenty-two studies that examined the factors related to CRC screening behaviors among the Chinese were identified through five databases. Seven factors were consistently reported to influence CRC screening behaviors in at least one of the studies: socio-demographic characteristics (educational level, health insurance, and knowledge about CRC and its screening); psychological factors (perceived severity of CRC, susceptibility of having CRC, and barriers to screening); and contact with medical provider (physician recommendation). The evidence base for many of these relationships is quite limited. Furthermore, the associations of many factors, including age, gender, income, cancer worry/fear, and self-efficacy with CRC screening behaviors, were mixed or inconsistent across these studies, thereby indicating that more studies are needed in this area.

Abstract
PURPOSE The prevalence of colorectal cancer (CRC) among older people is high. Screening for CRC presents a cost-effective secondary prevention and control strategy which results in a significant reduction in mortality. This study aims to describe the prevalence of CRC screening and examine its risk factors among Chinese community-dwelling older people guided by a comprehensive model combining Health Belief Model and Extended Parallel Processing Model. METHODS A descriptive correlational study was conducted. A convenience sample of 240 community-dwelling adults aged ≥60 was recruited in May-July in 2012 in Hong Kong. Participants were asked to complete a questionnaire which collected information on demographic variables, CRC-related psychosocial variables and whether they had a CRC screening in the past 10 years. RESULTS Among the participants, 25.4% reported having a CRC screening test. Results of logistic regression analyses indicated that participants with a higher level in cue to action, and lower perceived knowledge barriers and severity-fear were significantly associated with participation in CRC screening. But there were no significant associations between fatalism and cancer fear with screening. CONCLUSIONS The prevalence of CRC screening was low in Hong Kong Chinese community-dwelling elders. A number of modifiable factors associated with CRC screening were identified which provides specific targets for interventions. This study also adds to the knowledge regarding the associations between fatalism and fear with CRC screening behaviors among Chinese older people.

Abstract
This paper seeks to understand the experiences of single colorectal cancer patients. This study consisted of 12 semi-structured interviews that were digitally voice-recorded, transcribed, and analyzed. Six main themes emerged: (a) gradual shift in view of cancer diagnosis from fatalistic to normalized, (b) perception of cancer as a nadir experience, (c) concerns of singlehood, (d) factors influencing cancer experiences, (e) factors influencing coping with cancer, and (f) range of responses towards cancer diagnosis. Singles with colorectal cancer require short- to long-term individualized care plans, and psycho-emotional support. This may help enhance their individual coping and adjustment to the diagnosis.

Abstract
We hypothesized that perceived risk of colorectal cancer (CRC) and CRC worry would be the main predictors of surveillance behavior in patients undergoing colonoscopy. We therefore assessed factors predicting colonoscopy use for re-examination one year after colonoscopy. Patients who had undergone colonoscopy and were scheduled for re-examination one year later were recruited. Patients were administered questionnaires after baseline colonoscopy assessing demographic factors, perceived risk, CRC worry, cancer preventability, knowledge of CRC and results of colonoscopy. We confirmed whether participants underwent colonoscopy re-examinations one year later (follow-up). Finally, 56 participants completed the research and were used in the final analysis (response rate = 65.1%). We found that 37.5% of the participants who underwent baseline colonoscopy underwent follow-up colonoscopy one year later. Follow-up colonoscopy was not significantly associated with any psychological variables, but was significantly associated with educational status (postsecondary) (odds ratio [OR] = 7.10, 95% confidence interval [CI] = 1.83-27.56) and the results of baseline colonoscopy in patients who did not undergo polypectomy but had remaining polyps (OR = 4.26, 95% CI = 1.02-17.84). Additionally, significant differences in cancer threat-related variables were observed among groups of patients who, during baseline colonoscopy, underwent polypectomy but had no remaining polyps, had polyps removed with some polyps remaining, or did not undergo polypectomy but had remaining polyps (p < .05), with the latter group having a significant relationship with repeat colonoscopy. Cancer threat-related variables were not predictive of repeat colonoscopy after one year. In contrast, patient educational status and the colonoscopy results were predictors. We also found a non-linear relationship between high CRC threat and inhibition of the screening behavior in that the CRC threat functions as motivation for the surveillance behavior of colonoscopy.

Abstract
PURPOSE The study aimed to explore the gender difference in using colorectal cancer (CRC) tests among Chinese aged 50 years or over. METHODS A cross-sectional study was conducted in 2004 Chinese older adults through anonymous telephone survey which covered socio-demographic variables, health status, use of complementary therapy, health-related perceptions and use of CRC tests. RESULTS The uptake rate of flexible sigmoidoscopy (FS)/colonoscopy was 14% for males and 10% for females, with males significantly more likely to have had the test after adjusting for their differences in socio-demographics, health status, use of complementary therapies, health-related perceptions and recommendation received from health professionals (adjusted OR = 1.5, 95% CI: 1.1-2.0, p = 0.005). The uptake of fecal occult blood test was nearly the same (19%) for both genders. Further interaction analyses indicates that the effect of a family history of cancer on the uptake of a FS/colonoscopy is significantly weaker in males than in females (the interaction odds ratio = 0.4, 95% CI: 0.2-0.8, p = 0.011), whereas a male perceived that visiting a doctor is good for health will be more likely to have an uptake of a FS/colonoscopy than a female with such perception (the interaction odds ratio = 2.1, 95% CI: 1.1-3.8, p = 0.018). CONCLUSIONS The uptake of CRC tests was low in this average-risk population. More effort is needed to educate the public about the importance and benefits of CRC tests. In view of the gender differences in some determinants of FS/colonoscopy uptake, particular attention should be given to develop gender-specific strategies to improve the rate.

Abstract
OBJECTIVE To investigate the diagnostic status of colorectal cancer (CRC) and the influence of early diagnosis and cancer stage in a tertiary care hospital in China. METHODS Face-to-face interviews were conducted in 364 consecutive CRC patients who had never participated in CRC screening. Initial symptoms, diagnosis and treatment delay were determined using a questionnaire. Factors influencing diagnostic status were analyzed using univariate analysis and logistic regression model. RESULTS A total of 307 patients were enrolled, in which 128 were with colon cancer and 179 with rectal cancer. The duration of diagnosis delay was significant longer than that of treatment delay. Unlike rectal cancer, colon cancer was likely to be treated at an advanced stage with a short interval between symptom onset and treatment. Colon cancer patients with a history of biliary tract or gallbladder stones, aged ≥ 50 years and with abdominal mass or intestinal obstruction as the initial symptom were diagnosed and treated much earlier. In rectal cancer, women and non-smokers were diagnosed and treated quickly. Factors correlated with early cancer stage were found in colon cancer, including bloody stool as the initial symptom (OR = 2.63, 95% CI 1.08-6.25, P = 0.034) and a history of appendectomy (OR = 4.00, 95% CI 1.15-14.29, P = 0.029). CONCLUSIONS The factors contributing to early cancer detection were identified but their clinical value is limited. Diagnosis by symptoms suggesting CRC needs to be improved and CRC screening should be vigorously promoted.

Abstract
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.

Abstract
OBJECTIVE Compliance with colorectal cancer screening recommendations requires considerable conscious effort on the part of the individual patient, making an individual's decisions about engagement in screening an important contributor to compliance or noncompliance. The objective of this paper was to examine the effectiveness of individual-level behavior theories and their associated constructs in accounting for engagement in colorectal cancer screening behavior. METHODS We reviewed the literature examining constructs from formal models of individual-level health behavior as factors associated with compliance with screening for colorectal cancer. All published studies examining one or more constructs from the health belief model, theory of planned behavior, transtheoretical model, or social cognitive theory and their relation to screening behavior or behavioral intentions were included in the analysis. RESULTS By and large, results of studies supported the theory-based predictions for the influence of constructs on cancer screening behavior. However, the evidence base for many of these relations, especially for models other than the health belief model, is quite limited. CONCLUSIONS Suggestions are made for future research on individual-level determinants of colorectal cancer screening.

Abstract
To assess the awareness and acceptability of colorectal cancer (CRC) screening in noncompliant Singaporeans and to determine if their barriers can be overcome by education. A questionnaire developed from thematic analysis of open-ended interviews with 72 subjects was administered to 580 residents in a local high-rise housing estate. Participants aware of CRC screening were assessed for barriers and acceptability of CRC screening. All participants were subsequently educated about CRC screening and reassessed for barriers and acceptance. Those keen for fecal occult blood testing (FOBT) were offered FOBT kits and followed up. CRC screening awareness was poor. Having no symptoms was the most common barrier. More barriers to FOBT than to colonoscopy were reduced with education. After education, acceptability toward FOBT increased but rejection rates rose even higher. FOBT is probably Singapore's most acceptable screening modality. Education is limited by barriers, which need to be overcome by alternative measures.

Abstract
OBJECTIVES Primary care physicians (PCPs) are influential in colorectal cancer (CRC) screening uptake in the community. This study aims to evaluate the factors associated with PCPs' practice of CRC screening among asymptomatic patients in a Chinese population. METHODS A validated postal questionnaire was sent to all practicing PCPs who were members of a community-based network in Hong Kong. Three separate rounds of reminder letters were sent to non-respondents. Binary logistic regression analysis was used with ever-referral for CRC screening in the past 12 months as the outcome variable. Predictor variables include physicians' gender, clinical experience, types of practice, and attitudes towards CRC screening. RESULTS Of 428 eligible physicians, 263 (61.4%) responded. A total of 187 physicians (71.1%) had referred patients for CRC screening in the past 1 year. Among all asymptomatic patients aged 50 years or older, physicians reported referring only 3.0% (1.0-10.0%) [median (interquartile range)] of patients. Colonoscopy (57.0%) and fecal occult blood testing (FOBT) (46.4%) were the most commonly recommended tests for these asymptomatic patients. Family history of CRC (58.6%) and patients' concern about CRC (50.2%) were major reasons for referral. PCPs in private practice (adjusted odds ratio [aOR] 2.60, 95% C.I. 1.21-5.59) and those with positive attitude towards CRC screening (aOR 2.27, 95% C.I. 1.15-4.48) were more likely to recommend CRC screening. CONCLUSIONS PCPs' attitude towards CRC screening is a significant determinant of its practice. Future studies should identify and strengthen the influencers of PCPs' attitude to enhance CRC screening rates.

Abstract
AIM: To investigate barriers to colorectal cancer (CRC) screening in a community population.
METHODS: We conducted a community-based case-control study in an urban Chinese population by questionnaire. Cases were selected from those completing both a fecal occult blood test (FOBT) case and colonoscopy in a CRC screening program in 2004. Control groups were matched by gender, age group and community. Control 1 included those having a positive FOBT but refusing a colonoscopy. Control 2 included those who refused both an FOBT and colonoscopy.
RESULTS: The impact of occupation on willingness to attend a colorectal screening program differed by gender. P for heterogeneity was 0.009 for case vs control group 1, 0.01 for case versus control group 2, and 0.80 for control group 1 vs 2. Poor awareness of CRC and its screening program, characteristics of screening tests, and lack of time affected the screening rate. Financial support, fear of pain and bowel preparation were barriers to a colonoscopy as a screening test. Eighty-two percent of control group 1 and 87.1% of control group 2 were willing attend if the colonoscopy was free, but only 56.3% and 53.1%, respectively, if it was self-paid. Multivariate odds ratios for case vs control group 1 were 0.10 among those unwilling to attend a free colonoscopy and 0.50 among those unwilling to attend a self-paid colonoscopy.
CONCLUSION: Raising the public awareness of CRC and its screening, integrating CRC screening into the health care system, and using a painless colonoscopy would increase its screening rate.

Abstract
Background Limited evidence suggests that people from non-English speaking backgrounds in Australia have lower than average rates of participation in cancer screening programs. The objective of this study was to examine the distribution of bowel, breast and prostate cancer test use by place of birth and years since migration in a large population-based cohort study in Australia. Methods In 2006, screening status, country of birth and other demographic and health related factors were ascertained by self-completed questionnaire among 31,401 (16,126 women and 15,275 men) participants aged 50 or over from the 45 and Up Study in New South Wales. Results 35% of women and 39% of men reported having a bowel cancer test and 57% of men reported having a prostate specific antigen (PSA) test, in the previous 5 years. 72% of women reported having screening mammography in the previous 2 years. Compared to Australian-born women, women from East Asia, Southeast Asia, Continental Western Europe, and North Africa/Middle East had significantly lower rates of bowel testing, with odds ratios (OR; 95%CI) ranging from 0.5 (0.4–0.7) to 0.7 (0.6–0.9); migrants from East Asia (0.5, 0.3–0.7) and North Africa/Middle East (0.5, 0.3–0.9) had significantly lower rates of mammography. Compared to Australian-born men, bowel cancer testing was significantly lower among men from all regions of Asia (OR, 95%CI ranging from 0.4, 0.3–0.6 to 0.6, 0.5–0.9) and Continental Europe (OR, 95%CI ranging from 0.4, 0.3–0.7 to 0.7, 0.6–0.9). Only men from East Asia had significantly lower PSA testing rates than Australian-born men (0.4, 0.3–0.6). As the number of years lived in Australia increased, cancer test use among migrants approached Australian-born rates. Conclusion Certain migrant groups within the population may require targeted intervention to improve their uptake of cancer screening, particularly screening for bowel cancer.

Gender differences in the trend of colorectal cancer incidence in Singapore, 1968-2002. Int J Colorectal Dis 2008; 23:461-7. [PMID: 18185939 DOI: 10.1007/s00384-007-0421-9] [Citation(s) in RCA: 139] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 12/07/2007] [Indexed: 02/04/2023]
Abstract
BACKGROUND AND AIMS Over the past decades, incidence trends of colorectal cancer are sharply increased in Singapore. In this population-based study we describe changes in colorectal cancer incidence in Singapore and explore the reasons behind these changes through age-period cohort (APC) modeling. METHODS We included all 22,609 colorectal cancer cases reported to the Singapore Cancer Registry between 1968 and 2002. Poisson regression, using age-period (AP) and age-cohort (AC) models was used to determine the effects of age at diagnosis, calendar period, and birth cohort. RESULTS Male colorectal cancer rates between 1968 and 2002 from 20 to 40 per 100,000 person years. The increase was sharpest among older men, for whom there was a significant AC effect. Female colorectal cancer rates increased until 1992 (from 16 to 29 per 100,000 person years) and stabilized afterward. For women under 65 years, we observed a significant AP effect, corresponding to a sudden rise in colorectal cancer incidence around 1978. CONCLUSIONS This study demonstrates important gender differences in colorectal cancer incidence in Singapore, with increasing rates among men, and stabilized rates in women. The increase in men is mainly attributable to an incidence increase in the oldest age groups, probably due to increased exposure to dietary and lifestyle risk factors earlier in life. The stabilization in female colorectal cancer risk could be due to lower exposure to lifestyle risk factors and prophylactic removal of precancerous lesions.

Abstract
BACKGROUND Colorectal cancer (CRC) has emerged as the second most common cancer in Asia. This study uses the Health Belief Model (HBM) to examine the factors associated with the uptake of CRC testing. METHODS A population-based telephone survey in which 1,004 randomly selected Chinese residents of Hong Kong aged between 30 and 65 yr were interviewed in 2006. Instruments were developed to measure the variables pertinent to the HBM, including perceived susceptibility, severity, benefit, barriers, and cues to action. The relationships of these predictors with CRC testing were examined using bivariate and multiple logistic regression analyses. RESULTS Ten percent of the respondents had undertaken a CRC screening test. In the multiple logistic regression analyses, knowledge factors that were positively associated with CRC testing included knowledge of CRC symptoms (adjusted odds ratio [aOR] 3.33, 95% confidence interval [CI] 1.21-9.11) and knowledge of CRC risk factors (aOR 2.61, 95% CI 1.16-5.88). Five of the variables pertaining to the HBM were significant correlates of CRC testing-perceived severity of CRC (aOR 0.28, 95% CI 0.13-0.65), perceived health and psychological barriers to CRC testing (aOR 0.42, 95% CI 0.21-0.84, 95% CI 0.21-0.85), perceived access barriers to CRC testing (aOR 0.22, 95% CI 0.05-0.85), physician's recommendation (indicator of cues to action) (aOR 23.50, 95% CI 10.66-51.80), and having health insurance (indicator of cues to action) (aOR 2.06, 95% CI 1.01-4.19). CONCLUSIONS CRC testing compliance among this Asian population is low. Knowledge of CRC symptoms and risk factors are low. Perceived health, psychological, and access barriers to CRC testing are high. The physician's recommendation and having health insurance coverage significantly increase testing, but physicians mainly recommend patients with a family history of CRC for testing, and only around one-third of the population has health insurance.
