Promoting colonoscopy screening among low-income Latinos at average risk of colorectal cancer: A randomized clinical trial.

BACKGROUND: Screening colonoscopy (SC) for colorectal cancer (CRC) is underused by Latino individuals. The current randomized clinical trial examined the impact of 3 interventions: 1) patient navigation; 2) patient navigation plus standard Centers for Disease Control and Prevention print materials; and 3) patient navigation plus culturally targeted print materials for Latinos referred for SC. Demographic, personal and health history, and psychometric factors associated with SC also were examined. METHODS: A total of 344 urban Latino individuals aged 50 to 85 years with no personal and/or immediate family history of CRC diagnosed before age 60 years, no personal history of a gastrointestinal disorder, no colonoscopy within the past 5 years, with insurance coverage, and with a referral for SC were consented. Participants were randomized to patient navigation (20%), patient navigation plus standard Centers for Disease Control and Prevention print materials (40%), and patient navigation plus culturally targeted print materials (40%). The completion of SC was assessed at 12 months. RESULTS: The interventions had an overall SC rate of 82%. Counterintuitively, patients with an average income of <$10,000 were found to have higher SC rates (87%) than those with a greater income (75%). CONCLUSIONS: The addition of standard or culturally targeted print materials did not appear to increase SC rates above those for patient navigation. Indeed, after controlling for other variables, culturally targeted print materials were found to be associated with lower SC rates among Puerto Rican individuals.

Adenoma Prevalence and Distribution Among US Latino Subgroups Undergoing Screening Colonoscopy.

BACKGROUND: Colorectal cancer (CRC) is the second leading malignancy diagnosed among US Latinos. Latinos in the USA represent a heterogeneous amalgam of subgroups varying in genetic background, culture, and socioeconomic status. Little is known about the frequency of CRC precursor lesions found at screening colonoscopy among Latino subgroups. AIM: The aim was to determine the prevalence and distribution of histologically confirmed adenomas found at screening colonoscopy among average-risk, asymptomatic US Latinos according to their subgroup and socio-demographic background. METHODS: Cross-sectional analysis of pathological findings resulting from screening colonoscopy among average-risk, asymptomatic US Latinos aged ≥50 in two prospective randomized controlled trials at an academic medical center. RESULTS: Among the 561 Latinos who completed screening colonoscopy, the two largest subgroups were Puerto Ricans and Dominicans. The findings among both subgroups were: adenomas 30.6%, proximal adenomas 23.5%, advanced adenomas 12.0%, and proximal advanced adenomas 8.9%. These rates are at least as high as those found at screening colonoscopy among US whites. While Puerto Ricans were more likely than Dominicans to be born in the USA, speak English, be acculturated, have a smoking history, and be obese, there were no significant differences in adenoma rates between these subgroups. CONCLUSIONS: The prevalence of adenomas, advanced adenomas, and proximal neoplasia was high among both subgroups. These findings have implications for CRC screening and surveillance among the increasingly growing Latino population in the USA.

Examining the Impact of Latino Nativity, Migration, and Acculturation Factors on Colonoscopy Screening.

Latinos are a diverse population comprised of multiple countries of origin with varying cultural profiles. This study examines differences in colonoscopy completion across place of birth and migration-related factors in a sample of predominantly Dominican and Puerto Rican Latinos living in New York City after receiving a recommendation for colonoscopy screening and navigation services. The sample included 702 Latinos recruited for two cancer screening projects targeting Latinos eligible for colonoscopy who seek healthcare in New York City. Participants completed a survey that included sociodemographic, health-related questions, psychosocial assessments and cancer screening practices, in Spanish or English. Migration, acculturation, and language factors were found to predict colonoscopy completion. The results indicated that Latinos born in the Dominican Republic and Central America were more likely to complete a screening colonoscopy than their counterparts born in the US. Further, those who emigrated at an older age, who have resided in the US for less than 20 years, preferred Spanish and those with lower US acculturation levels were also more likely to complete a screening colonoscopy. The findings suggest that Latinos who are less acculturated to the US are more likely to complete a screening colonoscopy after receiving a physician recommendation for colonoscopy screening. The results provide important information that can inform clinical practice and public health interventions. Continued attention to cultural and migration influences are important areas for cancer screening intervention development.

Preventive Health Behaviors Among Low-Income African American and Hispanic Populations: Can Colonoscopy Screening Serve as a Teachable Moment?

INTRODUCTION: Teachable moments (TMs) are situations with potential for promoting health behavior change. Little is known as to whether colonoscopy screening itself may serve as a TM, particularly among low-income or minority populations. Research in this area is needed to inform efforts to address the disproportionate burden of colorectal cancer (CRC) experienced by minorities. AIMS: This study aims to describe attitudes related to physical activity (PA) and healthy eating among a low-income Hispanic and African American sample, assess whether colonoscopy completion may encourage changes in dietary behavior or PA, and determine the type of interventions minority participants would prefer to promote preventive behaviors. METHODS: Average-risk African American and Hispanic individuals who are referred for a screening colonoscopy at a Primary Care Clinic between May 2008 and December 2011 were eligible. Data were collected at three time points: at recruitment, 2 weeks before their colonoscopy, and 1 month after their colonoscopy (n = 537). RESULTS: The difference in change in PA from baseline to post-colonoscopy follow-up between those who had a colonoscopy and those who did not was significant (p = .04). Those who completed a colonoscopy increased their PA by 0.26 days on average, whereas, those who did not decreased their PA by 0.46 days. DISCUSSION: Findings suggest that the time following colonoscopy completion may be ideal to provide health promotion for PA and healthy eating. Future research is needed to explore the mechanisms that influence health behavior change as a result of colonoscopies to inform the development of interventions in this area.

Designing a randomized controlled trial to evaluate a community-based narrative intervention for improving colorectal cancer screening for African Americans.

OBJECTIVE: To describe the methodology of a 2-arm randomized controlled trial that compared the effects of a narrative and didactic version of the Witness CARES (Community Awareness, Reach, & Empowerment for Screening) intervention on colorectal cancer screening behavior among African Americans, as well as the cognitive and affective determinants of screening. METHODS: Witness CARES targeted cognitive and affective predictors of screening using a culturally competent, community-based, narrative or didactic communication approach. New and existing community partners were recruited in two New York sites. Group randomization allocated programs to the narrative or didactic arm. Five phases of data collection were conducted: baseline, post-intervention, three-month, six-month, and qualitative interviews. The primary outcome was screening behavior; secondary outcomes included cognitive and affective determinants of screening. RESULTS: A total of 183 programs were conducted for 2655 attendees. Of these attendees, 19.4% (N=516) across 158 programs (50% narrative; 50% didactic) were study-eligible and consented to participate. Half (45.6%) of the programs were delivered to new community partners and 34.8% were delivered at faith-based organizations. Mean age of the total sample was 64.7years and 75.4% were female. CONCLUSION: The planned number of programs was delivered, but the proportion of study-eligible attendees was lower than predicted. This community-based participatory research approach was largely successful in involving the community served in the development and implementation of the intervention and study.

Breast and Cervical Cancer Screening among US and non US Born African American Muslim Women in New York City.

PURPOSE: Health disparities related to breast and cervical cancer among African American and African-born Muslim women in the United States have been identified in previous literature. Our study aimed at exploring the breast and cervical screening rates and factors that influence this population's disposition to adhere to cancer screening exams. METHODS: Mixed methods were used to collect data with African American and African-born Muslim women in New York City. Data were collected from a total of 140 women; among them, 40 participated in four focus groups. FINDINGS: Focus groups revealed nine themes: healthcare practices; lack of knowledge/misconceptions; negative perceptions and fear; time; modesty; role of religion; role of men; role of community; stigma and shame. Among 130 women who reported their cancer screening status, 72.3% of those age 21 and over were adherent to cervical cancer screening; 20.0% never had a Pap test. Among women age 40 and over, 80.2% reported adherence to recommended mammogram; 12.8% never had one. Among women under age 40, 52.2% had their last clinical breast exam (CBE) less than three years ago. Among women age 40 and over, 75.0% were adherent to yearly CBE. CONCLUSIONS: While rates of screenings were above the national average and higher than expected, specific barriers and facilitators related to religious and health beliefs and attitudes that influence the decision to adhere to screening were revealed. These factors should be further explored and addressed to inform future research and strategies for promoting regular breast and cervical cancer screenings.

Co-Care: A Registry for Individuals at Increased Risk for Colorectal Cancer.

INTRODUCTION: Colorectal cancer (CRC) is one of the leading causes of cancer death for both men and women in the United States. Several factors can increase one's risk of CRC, including a personal or family history of CRC, a diagnosis or family history of a hereditary colon cancer syndrome, or a diagnosis of chronic inflammatory bowel disease. The purpose of this project was to create a colorectal cancer registry (Co-Care) for individuals with a personal or family history of CRC, and those with disorders of the colon or rectum that are associated with an increased risk for developing CRC. Methods: To be eligible for the registry, patients either had a personal or family history of CRC, a diagnosis or family history of Lynch syndrome, familial adenomatous polyposis, or a diagnosis of Crohn's colitis or ulcerative colitis with dysplasia. Participants were recruited after seeing their gastroenterologist or genetic counselor, or after undergoing a full or partial colectomy at Mount Sinai Hospital in New York City. Eligible patients who agreed to participate were interviewed by a member of the research staff and asked a wide range of questions pertaining to CRC risk. RESULTS: A total of 224 patients were enrolled in the registry. Participants are mostly white, born in the United States, and married, with a bachelor's or graduate degree, reporting an annual household income of $100,000 or more. The largest portion have a family history of CRC (27.2%), and almost half of participants are of Jewish descent (46.2%) and have undergone full or partial colectomy (48.2%). More than half of participants have neither received genetic counseling (54.5%) nor undergone genetic testing (59.7%). Only 3.6% report that they currently smoke cigarettes, and 41.1% consume alcohol at least once per week. Lastly, 18.3%, 10.3%, and 27.7% of participants report that they currently take aspirin, folic acid/folate pills or tablets, or calcium pills/tablets, respectively. CONCLUSIONS: This registry can improve our understanding of CRC and related diseases, and be used to design future interventions related to disease risk, prognosis, and prevention of CRC.

Increasing referral rate for screening colonoscopy through patient education and activation at a primary care clinic in New York City.

OBJECTIVE: Colorectal cancer could be prevented through regular screening. Individuals age 50 and older are recommended to get screened via colonoscopy. Because physician referral is a major predictor of colonoscopy completion, two low-cost, evidence-based interventions were tested to increase referrals by activating patients to self-advocate. METHODS: This study compared the impact of a pre-visit educational handout that prompts patients to discuss colonoscopy with their physician with the handout plus brief counseling through exit interviews and chart reviews. The main outcome was physician referral. RESULTS: Medical charts were reviewed for eligibility: 130 control patients (Arm 1), 45 patients who received the educational handout and health counseling (Arm 2), and 50 patients who received only the handout (Arm 3). Colonoscopy referral rates increased from 24.6% in Arm 1 to 44.4% and 52.0% in Arms 2 and 3, respectively (p=0.001). The proportion of exit interview participants who discussed colonoscopy with their doctor increased from 68.8% in Arm 1 to 76.5% and 88.9% in Arms 2 and 3, respectively. CONCLUSIONS: Results indicate that both interventions are effective at increasing colonoscopy referrals. PRACTICAL IMPLICATIONS: Results suggest that an educational handout alone is sufficient in prompting patient-initiated discussions about colonoscopy.

Examining Social Capital and Its Relation to Breast and Cervical Cancer Screening among Underserved Latinas in the U.S.

Many Latinos in the U.S. experience structural barriers to health care. Social capital and its implications for health and access to health care among this group are not well understood by researchers. This study examined associations between social capital and breast and cervical cancer screening adherence among a sample of 394 predominately Puerto Rican and Dominican women. Data were collected at baseline from Latinas attending screening education programs in Buffalo, New York and New York City in 2011-2012. Social capital was higher among Latinas who were older, better educated, insured, and spoke English. In multivariable logistic regression, a one unit increase in social capital index score was associated with greater adherence to Pap test (OR = 1.61), clinical breast exam (OR = 1.47) and mammography screening (OR = 1.50). Social capital should be further explored as a strategy to facilitate breast and cervical cancer screening among underserved Latinas.

A Mixed-Methods Evaluation of a SNAP-Ed Farmers' Market-Based Nutrition Education Program.

OBJECTIVE: Evaluate the effectiveness of the Stellar Farmers' Market program. DESIGN: Mixed methods including focus groups and a quasi-experiment comparing a control group of market shoppers who had never attended a class, participants attending 1 class, and participants attending ≥ 2 classes. SETTING: Eighteen farmers' markets in New York City. PARTICIPANTS: A total of 2,063 survey respondents; 47 focus group participants. INTERVENTION: Farmers' market-based nutrition education and cooking classes paired with vouchers for fresh produce. MAIN OUTCOME MEASURES: Attitudes, self-efficacy, and behaviors regarding fruit and vegetable (FV) preparation and consumption. ANALYSIS: Bivariate and regression analysis examined differences in outcomes as a function of number of classes attended. Qualitative analysis based on a grounded theory approach. RESULTS: Attending ≥ 1 classes was associated with more positive attitudes toward consuming FV; attending ≥ 2 classes was associated with greater FV consumption and higher self-efficacy to prepare and consume produce. Respondents attending ≥ 2 classes consumed almost one-half cup more FV daily than others. These associations remained after controlling for age, race/ethnicity, education, and gender. CONCLUSIONS AND IMPLICATIONS: Offering nutrition education and cooking classes at farmers' markets may contribute to improving attitudes, self-efficacy, and behaviors regarding produce preparation and consumption in low-income populations.

Factors related to hepatitis B screening among Africans in New York City.

OBJECTIVE: To understand factors that US Africans identify as barriers and facilitators for accessing hepatitis B (HBV) screening. METHODS: In-depth interviews were conducted and guided by the PEN-3 model to elicit culturally driven information in minority communities. RESULTS: Interviews were conducted with 22 US Africans. Salient themes that emerged were HBV knowledge, complexity of the US medical system, unaccustomed to preventive care, language and health literacy, availability and accessibility of screening, fear of disclosure, reliance on faith community, stigma of HBV, primacy towards a higher power on illnesses, and social systems influences. CONCLUSIONS: Findings were consistent with other at-risk populations, however, emphasis on privacy and fear of disclosure are distinct to Africans. This reinforces the need for a culturally targeted intervention for this at-risk population.

Expanding the Grading of Recommendations Assessment, Development, and Evaluation (Ex-GRADE) for Evidence-Based Clinical Recommendations: Validation Study.

Clinicians use general practice guidelines as a source of support for their intervention, but how much confidence should they place on these recommendations? How much confidence should patients place on these recommendations? Various instruments are available to assess the quality of evidence of research, such as the revised Wong scale (R-Wong) which examines the quality of research design, methodology and data analysis, and the revision of the assessment of multiple systematic reviews (R-AMSTAR), which examines the quality of systematic reviews.The Grading of Recommendation Assessment, Development, and Evaluation (GRADE) Working Group developed an instrument called the GRADE system in order to grade the quality of the evidence in studies and to evaluate the strength of recommendation of the intervention that is proposed in the published article. The GRADE looks at four factors to determine the quality of the evidence: study design, study quality, consistency, and directness. After combining the four components and assessing the grade of the evidence, the strength of recommendation of the intervention is established. The GRADE, however, only makes a qualitative assessment of the evidence and does not generate quantifiable data.In this study, we have quantified both the grading of the quality of evidence and also the strength of recommendation of the original GRADE, hence expanding the GRADE. This expansion of the GRADE (Ex-GRADE) permits the creation of a new instrument that can produce tangible data and possibly bridge the gap between evidence-based research and evidence-based clinical practice.
