Abstract: Introduction Although rates of invasive cervical cancer have declined precipitously over the past 50 years, nearly 10,000 new cases and 3700 deaths result from this cancer annually. Given the efficacy of early detection, invasive cervical cancer should no longer constitute a health threat; however, national studies reveal that many women, especially older women, do not receive Papanicolaou (Pap) tests. Methods In this complementary study, we examined data from the National Health Interview Survey focusing on the correlates of screening for women aged 55 years or older, an age group in which invasive cervical cancer rates escalate and rates of obtaining Pap tests decline. To more richly understand grounded perspectives, we queried 25 women who were rarely or never screened about factors and circumstances underlying their decision not to obtain a Pap test. Results Quantitative data indicate an association between Pap test use and demographic factors (being married, being younger, and having suburban or urban residence) and access to preventive care (obtaining mammograms, having a regular source of health care, and having contact with an obstetrician/gynecologist). Participants who provided qualitative data echoed this theme of inadequate use of preventive services, particularly among women with weak social ties, who were older, and who lived in rural areas. Shortages of health care professionals and a lack of continuity of care and privacy contribute to suboptimal prevention. Conclusion A vicious cycle emerges: many women decline to pursue preventive care because of competing health and financial demands and insufficient resources to seek care. When such women do go to the doctor’s office, they feel chastised by providers, which alienates them and thwarts future preventive care.

Abstract: Mixture models are used for spatially adaptive smoothing of health event data (e.g. mortality or illness totals). Such models allow for spatial pooling of strength where appropriate but adopt a mixture strategy that also reflects health risks that are discordant with those of surrounding areas. Mixing is either discrete or based on beta densities. A fully Bayesian estimation and specification strategy is applied with fit based on DIC and BIC criteria. Illustrative applications are to long term illness in 133 London small areas, where event counts are large, and to lip cancer in Scottish counties where the majority of event totals are under 10.

Abstract: Introduction West Virginia is the only state that lies entirely within Appalachia. West Virginians tend to be poorer and more likely to lack health insurance than the general U.S. population. The purpose of this qualitative study was to 1) obtain an understanding of attitudes about breast and cervical cancer screening among women aged 25 to 64 years; 2) determine factors that motivate women to be screened for breast and cervical cancer; and 3) evaluate educational materials about breast and cervical cancer screening for use in this population. Methods The West Virginia Breast and Cervical Cancer Screening Program (WVBCCSP) is a comprehensive public health program, funded by the Centers for Disease Control and Prevention, dedicated to removing barriers to breast and cervical cancer screening and providing screenings to underserved women aged 25 to 64 years. The program partnered with RMS Strategies, Inc, to conduct six focus groups in three communities in West Virginia. Women were recruited by telephone based on program eligibility guidelines. Results Results indicated that women were concerned about health care costs and lack of health insurance. Cost, fear, and embarrassment were identified as the top barriers to breast and cervical cancer screening. Participants believed that community-based educational campaigns would increase screening and promote use of the WVBCCSP. Conclusion Understanding why low-income Appalachian women do not get screened for breast and cervical cancer and determining motivational factors that encourage screening are important to increase screening rates among this population. Breast and cervical cancer efforts that use the words, knowledge, and suggestions of the women they serve are more likely to be effective and have a larger impact.

Abstract: Introduction Public health organizations in the United States emphasize the importance of providing routine screening for breast cancer, cervical cancer, and colorectal cancer, as well as vaccinations against influenza and pneumococcal disease among older adults. We report a composite measure of adults aged 50 years and older who receive recommended cancer screening services and vaccinations. Methods We analyzed state data from the 2002 Behavioral Risk Factor Surveillance System, which included 105,860 respondents aged 50 and older. We created a composite measure that included colonoscopy or sigmoidoscopy within 10 years or a fecal occult blood test in the past year, an influenza vaccination in the past year, a Papanicolaou test within 3 years for women with an intact cervix, a mammogram, and for adults aged 65 and older, a pneumonia vaccination during their lifetime. We performed separate analyses for four age and sex groups: men aged 50 to 64, women aged 50 to 64, men aged 65 and older, and women aged 65 and older. Results The percentage of each age and sex group that was up-to-date according to our composite measure ranged from 21.1% of women aged 50 to 64 (four tests) to 39.6% of men aged 65 and older (three tests). For each group, results varied by income, education, race/ethnicity, insurance status, and whether the respondent had a personal physician. Conclusion These results suggest the need to improve the delivery of cancer screenings and vaccinations among adults aged 50 and older. We propose continued efforts to measure use of clinical preventive services.

Abstract: Objective The objective of this study was to examine the association between inadequate functional health literacy in Spanish among low-income Latinas aged 40 and older and cervical cancer screening knowledge and behavior. Methods Spanish-speaking Latinas aged 40–78 of various nationalities (n = 205) participated in a study that included a survey on cervical cancer knowledge and behavior administered in Spanish and the Spanish version of the Test of Functional Health Literacy in Adults. Results Compared to those with adequate and marginal health literacy, women with inadequate functional health literacy in Spanish were significantly less likely to have ever had a Papanicolaou (Pap) test (odds ratio, 0.12; 95% confidence interval [CI], 0.04-0.37) or in the last three years (odds ratio, 0.35; 95% CI, 0.18-0.68) and were significantly more likely to have had their last Pap test at a local public hospital (odds ratio, 2.43; 95% CI, 1.18-4.97). Even when controlling for other factors, women with inadequate health literacy were 16.7 times less likely (adjusted odds ratio, 0.06; 95% CI, 0.01-0.55) to have ever had a Pap test. Conclusion Almost half of the population we studied will have difficulty interpreting written medical materials, even in Spanish. When developing efforts to reach women who have not been screened, programs and service providers need to be aware that the women most in need of information about screening may be more likely to be unable to read any written materials provided to them, regardless of the language or level of simplicity of the materials. Programs and strategies need to be implemented to increase screening prevalence and to minimize the identified gaps in regular screening for Latinas who have low health literacy.

Abstract: This paper discusses several data mining algorithms and techniques thatwe have developed at the University of Arizona Artificial Intelligence Lab.We have implemented these algorithms and techniques into severalprototypes, one of which focuses on medical information developed incooperation with the National Cancer Institute (NCI) and the University ofIllinois at Urbana-Champaign. We propose an architecture for medicalknowledge information systems that will permit data mining across severalmedical information sources and discuss a suite of data mining tools that weare developing to assist NCI in improving public access to and use of theirexisting vast cancer information collections.
