Beliefs about causes of colon cancer by English-as-a-Second-Language Chinese immigrant women to Canada

What do cancer survivors believe caused their cancer? A secondary analysis of cross-sectional survey data

PURPOSE

Given that risk reduction and healthy lifestyles can prevent 4 in 10 cancers, it is important to understand what survivors believe caused their cancer to inform educational initiatives.

METHODS

In this secondary analysis, we analyzed cancer survivor responses on the Causes Subscale of the Revised Illness Perception Questionnaire, which lists 18 possible causes of illness and a free text question. We used descriptive statistics to determine cancer survivors' agreement with the listed causes and conducted separate partial proportional odds models for the top three causes to examine their associations with sociodemographic and clinical characteristics. Content analysis was used to examine free text responses.

RESULTS

Of the 1,001 participants, most identified as Caucasian (n = 764, 77%), female (n = 845, 85%), and were diagnosed with breast cancer (n = 656, 66%). The most commonly believed causes of cancer were: stress or worry (n = 498, 51%), pollution in the environment (n = 471, 48%), and chance or bad luck (n = 412, 42%). The associations of sociodemographic and clinical variables varied across the models. Free text responses indicated that hereditary and genetic causes (n = 223, 22.3%) followed by trauma and stress (n = 218, 21.8%) and bad luck or chance (n = 79, 7.9%) were the most important causes of cancer.

CONCLUSIONS

Study results illuminate cancer survivors' beliefs about varying causes of their cancer diagnosis and identify characteristics of survivors who are more likely to believe certain factors caused their cancer. Results can be used to plan cancer education and risk-reduction campaigns and highlight for whom such initiatives would be most suitable.

Health literacy and meeting breast and cervical cancer screening guidelines among Asians and whites in California

Objectives

Empirical evidence regarding cancer screening and health literacy is mixed. Cancer is the leading cause of death in Asian Americans, yet screening rates are notably low. Using a population-based sample, we determined if health literacy: (1) was associated with breast and cervical cancer screening, and (2) helped to explain Asian cancer screening disparities.

Methods

We analyzed the 2007 California Health Interview Survey for Asian (Japanese, Chinese, Filipino, Korean, Vietnamese, other Asian) and white women within age groups relevant to US Preventive Services Task Force (USPSTF) screening guidelines: cervical: ages 21–65 (n = 15,210) and breast: ages 50–74 (n = 11,163). Multilevel logistic regression models predicted meeting USPSTF screening guidelines both with and without self-reported health literacy controlling for individual-level and contextual-level factors.

Results

Low health literacy significantly (p < 0.05) predicted lower cancer screening in final models for both cancer types. In unadjusted models, Asians were significantly less likely than whites to receive both screening types and significantly more likely to report low health literacy. However, in multivariable models, the addition of the low health literacy variable did not diminish Asian vs. white cancer screening disparities.

Conclusions

Self-reported health literacy predicted cervical and breast cancer screening, but was not able to explain Asian cancer screening disparities. We provide new evidence to support a relationship between health literacy and cancer screening. Health literacy is likely a useful focus for interventions to improve cancer screening and ultimately reduce the burden of cancer. To specifically reduce Asian cancer disparities, additional areas of focus should be considered.

Engaging traditional medicine providers in colorectal cancer screening education in a chinese american community: a pilot study

INTRODUCTION

Although colorectal cancer (CRC) screening is effective in preventing colon cancer, it remains underused by Asian Americans. Because Chinese Americans often use traditional Chinese medicine (TCM), we conducted a pilot study to explore the feasibility and acceptability of having TCM providers deliver education about CRC screening.

METHODS

Four TCM providers (2 herbalists and 2 acupuncturists) were trained to deliver small-group educational sessions to promote CRC screening. Each provider recruited 15 participants aged 50 to 75. Participants completed a baseline survey on CRC-related knowledge, attitudes, and behaviors and then attended one 2-hour educational session delivered by the providers in Cantonese or Mandarin. Three months later, participants completed a postintervention survey.

RESULTS

Sixty participants were recruited from the San Francisco Chinatown neighborhood. The average age was 62.4 years. Most participants had limited English proficiency (96.7%), annual household income less than $20,000 per year (60%), and low educational attainment (65.1% < high school education). At postintervention (n = 57), significant increases were found in having heard of CRC (from 52.6% to 79.0%, P < .001) and colon polyps (from 64.9% to 84.2%, P < .001). Knowledge regarding screening frequency recommendations also increased significantly. The rate of ever having received any CRC screening test increased from 71.9% to 82.5% (P <.001). The rate of up-to-date screening increased from 70.2% to 79.0% (P = .04).

CONCLUSION

The findings suggest that TCM providers can be trained to deliver culturally and linguistically appropriate outreach on CRC screening within their community. Participants reached by TCM providers increased CRC knowledge and self-reported CRC screening.

Exploring a Culturally Relevant Model of Cancer Prevention Involving Traditional Chinese Medicine Providers in a Chinese American Community

INTRODUCTION

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in all racial and ethnic groups. Although CRC screening is very cost-effective, screening rates are low among most ethnic groups, including Asian Americans. Given the high use of traditional Chinese medicine (TCM) among Chinese Americans one potentially useful approach to promote CRC screening in these communities could involve TCM providers in outreach efforts.

METHODS

A two-phase study was conducted. The perceived suitability of TCM providers in CRC prevention was explored in Phase 1. Guided by Phase 1 findings, in Phase 2, a 38-page integrative educational flipchart was developed and tested. Focus groups and observations were conducted with TCM providers (acupuncturists and herbalists) and with limited English proficient Chinese American immigrants living in San Francisco, California.

RESULTS

In Phase 1, the role of TCM providers as CRC screening educators was deemed acceptable by both providers and community members, although some providers had reservations about engaging in CRC outreach activities due to lack of expertise. The majority of providers were not aware of regular CRC screening as a preventive measure, and most were not up-to-date in their own screening. In Phase 2, the integrative CRC education flipchart was perceived as culturally appropriate based on stakeholder input and feedback.

CONCLUSION

This study shows that TCM providers have the potential to be a valuable and culturally appropriate community resource for providing information on CRC screening. It suggests a potential role for traditional healers as change agents in the immigrant community health network.
