Colorectal cancer test use among Hispanic and non-Hispanic U.S. populations.

INTRODUCTION: Although colorectal cancer mortality rates in the general U.S. population declined slightly from 1992 to 2000, the rates for Hispanic men and women did not. Disparity in colorectal cancer screening among Hispanics may be an important factor in the unchanged mortality trends. This study examined rates of colorectal cancer test use among Hispanic and non-Hispanic adults in the United States. METHODS: Using sampling weights and logistic regression, we analyzed colorectal cancer test use among 5680 Hispanic and 104,733 non-Hispanic adults aged 50 years and older who participated in the 2002 Behavioral Risk Factor Surveillance System. We estimated the percentages and adjusted odds ratios (ORs) of the respondents' reported test use by sociodemographic characteristics, health care access, and state or territory of residence. RESULTS: Hispanic respondents aged 50 and older reported having had either a fecal occult blood test within the past year or a lower endoscopy (sigmoidoscopy or colonoscopy) within 10 years less frequently (41.9%) than non-Hispanic respondents (55.2%). Rates of test use were lower for respondents who reported less education, lower income, no health insurance, and no usual source of health care, regardless of Hispanic ethnicity. After adjusting for differences in education, income, insurance, and having a usual source of health care, Hispanic respondents remained less likely than non-Hispanic respondents to report colorectal cancer testing (OR for fecal occult blood test, 0.66; 95% confidence interval [CI], 0.56-0.81; OR for lower endoscopy, 0.87; 95% CI, 0.77-0.99). Greater disparity in screening rates between Hispanics and non-Hispanics was observed in Colorado, California, and Texas than in other states. CONCLUSION: A disparity exists between Hispanic and non-Hispanic U.S. adults in colorectal cancer test use. This disparity varies among the states, highlighting the diverse health care experience of Hispanic adults in the United States.

Considerations in recruiting underscreened women to focus groups on screening for cervical cancer.

This article describes recruitment activities and costs from two independently conducted studies that used similar, systematic approaches to recruiting two subgroups of underscreened women, Black women and Mexican women. The studies varied in number of recruiters, venues of recruitment, and region of the country. The ratio of women approached to women who were underscreened was 4:1 for Black women and 10:1 for Mexican women. Hysterectomy was a predominant reason for ineligibility among Black women but not Mexican women. In both studies, personal networks were the most productive method of identifying women. Flyers and organized community venues were least productive. The cost incurred for identifying a woman who was eligible for a focus group was 145 dollars for Black women and 59 dollars for Mexican women. Those planning research or program activities that include recruiting underscreened women either to focus groups or health services could benefit from this information.

Promoting cancer screening: Learning from experience.

This article provides an overview of behavioral and social science cancer screening intervention research and introduces the scope of topics addressed in this supplement to Cancer. The authors identify and address issues to consider before conducting interventions to promote the uptake of screening tests, such as the benefits and harms associated with screening. Trends in the use of cancer screening tests are discussed in the context of their efficacy and adoption over time. Both the development and breadth of social and behavioral intervention research intended to increase the use of effective tests are reviewed as background for the articles that follow. The application of the lessons from this extensive knowledge base not only should accelerate the uptake of the effective cancer screening tests currently available, but also can guide future directions for research.

Disseminating effective cancer screening interventions.

A large gap exists between the results of research concerning efficacious cancer screening programs and the programs delivered in practice. In this article, the authors discuss issues in, barriers to, and lessons learned regarding the dissemination of interventions. They summarize previous reviews, exemplary studies, and theories regarding the diffusion and dissemination of cancer screening interventions. Six lessons learned address the involvement of key stakeholders, factors influencing diffusion, the need for different types of efficacy and effectiveness studies with greater attention to external validity, replication, the use of theoretical and evaluation models, and the importance of policy infrastructure. In this article, the authors make recommendations for future research and practice, including improving the understanding of the intervention process and changing the types of grants funded and review criteria used. Also needed are an enhanced infrastructure, including policies to support dissemination, and the involvement of researchers, health care administrators, clinicians, and funding organizations in dissemination if the gap between research and practice in cancer screening is to be reduced.

Interventions to prevent skin cancer by reducing exposure to ultraviolet radiation: a systematic review.

The relationship between skin cancer and ultraviolet radiation is well established. Behaviors such as seeking shade, avoiding sun exposure during peak hours of radiation, wearing protective clothing, or some combination of these behaviors can provide protection. Sunscreen use alone is not considered an adequate protection against ultraviolet radiation. This report presents the results of systematic reviews of effectiveness, applicability, other harms or benefits, economic evaluations, and barriers to use of selected interventions to prevent skin cancer by reducing exposure to ultraviolet radiation. The Task Force on Community Preventive Services found that education and policy approaches to increasing sun-protective behaviors were effective when implemented in primary schools and in recreational or tourism settings, but found insufficient evidence to determine effectiveness when implemented in other settings, such as child care centers, secondary schools and colleges, and occupational settings. They also found insufficient evidence to determine the effectiveness of interventions oriented to healthcare settings and providers, media campaigns alone, interventions oriented to parents or caregivers of children, and community-wide multicomponent interventions. The report also provides suggestions for areas for future research.

Breast and cervical cancer screening among migrant and seasonal farmworkers: a review.

Women constitute about one in five hired farmworkers in the US. Their health may be affected by exposure to unhealthy living and working conditions, by increased exposure to health hazards, by poverty, and by poor utilization of health care and preventive services. About 69% of migrant and seasonal farmworkers were born outside the US, mostly in Mexico and central America, and many speak little English. The health concerns of women who are migrant and seasonal farmworkers include breast and cervical cancer, which can be prevented or controlled through routine screening, but cancer incidence and mortality data for migrant workers are sparse. We reviewed published studies that examined breast and cervical cancer screening in this population. These studies include cross-sectional surveys, health needs assessments, and randomized and non-randomized intervention trials. A review of published studies of cancer screening among women who are migrant and seasonal farmworkers indicates that underutilization of mammograms and Papanicolau (Pap) tests among this population may stem from their limited awareness of the importance of cancer screening and cultural beliefs. Other barriers include cost, lack of health insurance, lack of transportation and child care difficulties. The extent to which results obtained in selected localities are generalizable to other settings is uncertain, but results to date provide important information about possible approaches for increasing cancer screening among women migrant farmworkers.

Breast and cervical cancer screening practices among Hispanic and non-Hispanic women residing near the United States-Mexico border, 1999-2000.

This study examined the breast and cervical cancer screening practices of Hispanic and non-Hispanic women (n = 3,568) in counties that approximate the US southern border region. According to the Health Resources Services Administration (HRSA), border counties are those in which any part of the county is within 100 kilometers (62.14 miles) of the border. The study used data from Behavioral Risk Factor Surveillance System (BRFSS) surveys of adults aged > or = 18 years conducted in 1999 and 2000. The study looked at recent use of mammography and the Papanicolaou (Pap) test. Hispanic women were less likely to have had a recent mammogram or Pap test as compared with non-Hispanic women in border counties, and as compared with Hispanic and non-Hispanic women in nonborder counties of Texas, New Mexico, Arizona, and California combined, and with other women in the United States. Results underscore the need for continued efforts to ensure that medically underserved women who live in the border region have access to cancer screening services.
