Cancer Information-Seeking Experiences: The Implications of Hispanic Ethnicity and Spanish Language

Background. Strategies to support cancer information-seeking among Hispanics are needed. Methods. We analyzed data from the 2005 Health Information National Trends Survey (HINTS) to explore cancer information-seeking experiences among respondents according to ethnicity and language of interview. Results. Over 80% of Spanish-speaking Hispanics had never looked for cancer information. Compared to English-speaking respondents, Spanish-speaking Hispanics who sought cancer information indicated their search took a lot of effort (67%), was hard to understand (54%), and frustrating (42%). Spanish-speaking Hispanics noted minimal confidence in obtaining cancer information. Conclusions. Language and cultural differences must be considered in the design, implementation, and dissemination of cancer information.

Uptake of Free HPV Vaccination Among Young Women: A Comparison of Rural Versus Urban Rates

PURPOSE To contrast rates of initial HPV vaccine uptake, offered at no cost, between a rural clinic, a rural community college, and an urban college clinic and to identify rural versus urban differences in uptake of free booster doses. METHODS Young rural women attending rural clinics (n = 246), young women attending a rural community college (n = 251) and young women attending an urban university health clinic (n = 209) were recruited in Kentucky. After completing a brief questionnaire, women received a free voucher for HPV vaccination. Whether women redeemed the voucher for the initial dose of vaccine served as the study outcome variable. FINDINGS In controlled analyses, the contrast in initial uptake between urban clinic women (reference category) and rural college women was significant (P < .0001). However, the contrast in initial uptake between urban clinic women (reference category) and rural clinic women was not significant (P = .42). The model predicting uptake of subsequent doses among those with initial uptake (n = 235) also indicated significant differences as a function of recruitment location, with rural clinic women being about 7 times more likely than urban clinic women (P < .0001) to not return for at least 1 follow-up dose. The contrast between urban clinic women and rural college women was also significant (P = .014). CONCLUSION Initial uptake of free HPV vaccination among young rural college women may be problematic. Moreover, uptake of subsequent free doses among rural women may be problematic regardless of whether contact is made in a clinic or through college recruitment.

Knowledge of HPV among United States Hispanic women: opportunities and challenges for cancer prevention.

In the United States, Hispanic women contribute disproportionately to cervical cancer incidence and mortality. This disparity, which primarily reflects lack of access to, and underutilization of, routine Pap smear screening may improve with increased availability of vaccines to prevent Human Papillomavirus (HPV) infection, the principal cause of cervical cancer. However, limited research has explored known determinants of HPV vaccine acceptability among Hispanic women. The current study examines two such determinants, HPV awareness and knowledge, using data from the 2007 Health Interview National Trends Survey (HINTS) and a cross-section of callers to the National Cancer Institutes (NCI) Cancer Information Service (CIS). Study data indicate that HPV awareness was high in both samples (69.5% and 63.8% had heard of the virus) but that knowledge of the virus and its association with cervical cancer varied between the two groups of women. The CIS sample, which was more impoverished and less acculturated than their HINTS counterparts, were less able to correctly identify that HPV causes cervical cancer (67.1% vs. 78.7%) and that it is a prevalent sexually transmitted infection (STI; 66.8% vs. 70.4%). Such findings imply that future research may benefit from disaggregating data collected with Hispanics to reflect important heterogeneity in this population subgroups ancestries, levels of income, educational attainment, and acculturation. Failing to do so may preclude opportunity to understand, as well as to attenuate, cancer disparity.

Cancer Risk Perceptions, Beliefs, and Physician Avoidance in Appalachia: Results from the 2008 HINTS Survey

Appalachians experience increased rates of cancer incidence and mortality and high-risk health behaviors. Additionally, Appalachians are often characterized by lower socioeconomic status, geographic isolation, and cultural beliefs such as fatalism. The purpose of this descriptive analysis is to identify cancer-related risk perceptions, beliefs, and physician avoidance behaviors among Appalachians as compared with non-Appalachians using data from the National Cancer Institutes 2008 Health Information National Trends Survey (HINTS), which contained a newly created “Appalachia” variable. Results suggest that compared with non-Appalachians, Appalachians have a significantly higher perceived risk of developing cancer in the future and are significantly more likely to associate cancer with death; believe individuals can tell they have cancer before a diagnosis; believe everything causes cancer; and admit to avoiding their physician even when they suspect they should plan a visit. Both Appalachians and non-Appalachians share similar mistaken beliefs about cancer prevention, screening, and curability, and frustration over the abundance of cancer prevention recommendations. In a geographic region recognized for cancer health disparities, development of tailored communication strategies and educational interventions designed to increase cancer knowledge may help to accurately explain cancer risk and incidence, dispel negative cancer beliefs, and promote a positive image of the doctor–patient relationship.

Health Care Avoidance Among Rural Populations: Results From a Nationally Representative Survey

BACKGROUND Previous research suggests that certain populations, including rural residents, exhibit health care avoidant behaviors more frequently than other groups. Additionally, health care avoidance is related to sociodemographics, attitudes, social expectations, ability to pay for care, and prior experiences with providers. However, previous studies have been limited to specific geographic areas, particular health conditions, or by analytic methods. METHODS The 2008 Health Information Trends Survey (HINTS) was used to estimate the magnitude of health care avoidance nationally and, while controlling for confounding factors, identify groups of people in the United States who are more likely to avoid health care. Chi-square procedures tested the statistical significance (P < .05) of bivariate relationships. Multivariable analysis was conducted through a weighted multiple logistic regression with backward selection. RESULTS For 6,714 respondents, bivariate analyses revealed differences (P < .05) in health care avoidance for multiple factors. However, multiple regression reduced the set of significant factors (P < .05) to rural residence (OR = 1.69), male sex (OR = 1.24), younger age (18-34 years OR = 2.34; 35-49 years OR = 2.10), lack of health insurance (OR = 1.43), lack of confidence in personal health care (OR = 2.24), lack of regular provider (OR = 1.49), little trust in physicians (OR = 1.34), and poor provider rapport (OR = 0.94). CONCLUSION The results of this study will help public health practitioners develop programs and initiatives targeted and tailored to specific groups, particularly rural populations, which seek to address avoidant behavior, thereby reducing the likelihood of adverse health outcomes.

HPV Vaccination Among Young Adult Women: A Perspective From Appalachian Kentucky

Introduction Few studies have assessed barriers to human papillomavirus (HPV) vaccination uptake and adherence, particularly among women of Appalachian Kentucky, a population with higher rates of cervical cancer, lower rates of HPV vaccination, and lower socioeconomic status compared with the rest of the nation. The objective of this study was to address women’s reasons for declining the HPV vaccine and, among women who initiated the vaccine series, barriers to completion of the 3-dose regimen. Methods We recruited 17 women aged 18 to 26 from a Federally Qualified Health Center who participated in in-depth, semistructured telephone interviews. All interviews were audio-recorded and transcribed verbatim; analysis of the interview transcripts was an iterative process conducted by all 3 authors. Results We identified 3 primary barriers: 1) a knowledge gap wherein women are both uninformed and misinformed about cervical cancer, HPV, and the HPV vaccine, all of which affect vaccination behaviors; 2) environmental and tangible barriers (transportation and prioritizing health over other responsibilities such as child care, work, and school); and 3) ambiguous information sources, which contribute to misinformation and subsequently affect vaccination decisions. Conclusion Health professionals should use clear and purposeful communication about how cervical cancer develops, the purpose and safety of the HPV vaccine, and the necessity of completing the 3-dose series. Health promotion campaigns and services tailored for young women in Appalachian Kentucky that focus on increasing knowledge and eliminating barriers are needed.

Perceptions of Cancer Controllability and Cancer Risk Knowledge: The Moderating Role of Race, Ethnicity, and Acculturation

Literature suggests racial/ethnic minorities, particularly those who are less-acculturated, have stronger fatalistic attitudes toward cancer than do non-Latino Whites. Knowledge of cancer prevention is also lower among racial/ethnic minorities. Moreover, low knowledge about cancer risk factors is often associated with fatalistic beliefs. Our study examined fatalism and cancer knowledge by race/ethnicity and explored whether race/ethnicity moderate the association of fatalism with knowledge of cancer prevention and risk factors. We analyzed data from the Health Information National Trends Survey (2008), a national probability survey, to calculate population estimates of the associations among race/ethnicity, fatalistic beliefs, and knowledge about cancer from multivariable logistic regression. Racial/ethnic minorities had higher odds of holding fatalistic beliefs and lower odds of having knowledge of cancer risk factors than non-Hispanic Whites, and important differences by acculturation among Latinos were observed. Limited evidence of the moderating effect of race/ethnicity on the relationship between fatalistic beliefs and cancer risk factor knowledge was observed. Knowledge of cancer risk factors is low among all race/ethnicities, while fatalistic beliefs about cancer are higher among racial/ethnic minorities compared with non-Hispanic Whites. Implications for cancer education efforts are discussed.

The African American Women and Mass Media Campaign: A CDC Breast Cancer Screening Project

For decades, black radio has reached African American communities with relevant, culturally appropriate information, and it continues to be an ideal communication channel to use for contemporary health promotion. In an effort to combat excess breast cancer mortality rates and help eliminate cancer disparities among low-income African American women, the Centers for Disease Control and Preventions (CDC) Division of Cancer Prevention and Control designed, implemented, and evaluated the African American Women and Mass Media (AAMM) pilot campaign. The AAMM campaign uses black radio, radio stations with broad African American listenership, as a platform for targeted, culturally competent health promotion and outreach to low-income, African American women. The AAMM campaign uses radio advertisements and print materials disseminated in predominantly African American neighborhoods to promote awareness of breast cancer, early detection, and the CDCs National Breast and Cervical Cancer Early Detection Program (NBCCEDP). Evaluation of the AAMM campaign found that the campaign successfully reached its target audience of low-income, African American women and increased womens awareness of breast cancer screening services through the Breast and Cervical Cancer Program in Savannah and Macon, Georgia.

Self-collecting a cervico-vaginal specimen for cervical cancer screening: An exploratory study of acceptability among medically underserved women in rural Appalachia

OBJECTIVE Innovative screening methods such as self-testing for human papillomavirus (HPV) may alleviate barriers to cervical cancer screening. The purpose of this exploratory study was to determine whether Appalachian Kentucky women would be amenable to self-collecting a cervico-vaginal specimen for HPV testing. METHODS Women aged 30-64 who were overdue for guideline-recommended cervical cancer screening were recruited from a primary care clinic in southeastern Kentucky. The women were asked to self-collect a specimen, using a cervico-vaginal brush, based on verbal and printed directions provided by a research nurse. All study participants, regardless of laboratory-confirmed HPV status, received the same counseling on the importance of cervical cancer screening and offered navigation to follow-up Pap testing at the local health department. RESULTS Thirty-one women were approached and recruited to participate in the study, indicating a 100% acceptance rate of HPV self-testing. Of the 31 women, 26 tested negative for high-risk HPV and five tested positive. All of the women with negative results declined nurse navigation to Pap testing, whereas four of the five women with positive results accepted nurse navigation and received subsequent Pap smear screenings (all results were normal). CONCLUSIONS Among this sample of Appalachian Kentucky women, self-collecting a cervico-vaginal specimen for HPV testing was highly acceptable. This exploratory study provides impetus for larger studies among high-risk, medically underserved women in rural communities. Tailoring alternative cancer screening strategies to meet the complex needs of rural women is likely to lead to reductions in cervical cancer incidence and mortality among this vulnerable population.

Sexually Related Behaviors as Predictors of HPV Vaccination Among Young Rural Women

PURPOSE To explore whether sexually related behaviors predict refusal of the human papillomavirus (HPV) vaccine among a sample of women aged 18-26 in Appalachian Kentucky. METHODS Using a convenience sample, young women attending health clinics and a community college in southeastern Kentucky were recruited to participate in a Womens Health Study. After completing a questionnaire, women received a free voucher for the three-dose HPV vaccine series. Completion of dose one served as the outcome variable. RESULTS Women with a history of an abnormal Pap test were almost two times more likely to decline the HPV vaccine (adjusted odds ratio [AOR] 1.91, 95% confidence interval [CI] 1.14-3.20, p=0.015), and women who reported they had never had a Pap test were four times more likely to decline the vaccine (AOR 4.02, 95% CI 1.13-14.32, p=0.032). Women engaging in mutual masturbation were nearly two times more likely to decline the free vaccine (AOR 1.91, 95% CI 1.17-3.10, p=0.009). Use of hormonal birth control showed a protective effect against refusal of the free HPV vaccine (AOR 0.593, 95% CI 0.44-0.80, p=0.001). CONCLUSIONS Among this sample of Appalachian women, those engaging in behaviors that increase their risk for HPV infection were more likely to refuse the vaccine. Conversely, those women engaging in protective health behaviors were more likely to accept the vaccine. These findings suggest that those women not being vaccinated may be the very group most likely to benefit from vaccination. Cervical cancer prevention programs need to be creative in efforts to reach young women most in need of the vaccine based on a higher profile of sexually related behaviors and the proxy measure of this risk (having an abnormal Pap test result).
