Cervical cancer screening among Chinese immigrants in Seattle, Washington

Introduction: Chinese American women have high rates of invasive cervical cancer, compared to the general population. However, little is known about the Pap testing behavior of ethnic Chinese immigrants.Methods: We conducted a community-based survey of Chinese immigrants living in Seattle, Washington, during 1999. Two indicators of cervical cancer screening participation were examined: at least one previous Pap smear and Pap testing in the last 2 years.Results: The overall estimated response rate was 64%, and the cooperation rate was 72%. Our study sample for this analysis included 647 women. Nearly one quarter (24%) of the respondents had never had a Pap test, and only 60% had been screened recently. Factors independently associated with cervical cancer screening use included marital status, housing type, and age at immigration.Conclusion: Our findings confirm low levels of cervical cancer screening among Chinese immigrants to North America. Culturally and linguistically appropriate Pap testing intervention programs for less acculturated Chinese women should be developed, implemented, and evaluated.     

Predictors of Compliance with Recommended Cervical Cancer Screening Schedule: A Population-Based Study

Background: The prevalence of routine cervical cancer screening and compliance with screening schedules are low compared to the Year 2000 objectives. Identifying predictors of routine screening and screening schedule compliance will help achieve these objectives. Methods: We analyzed data from probability samples of 1,609 Missouri women responding to both the 1994 Behavioral Risk Factor Surveillance System (BRFSS) and the Missouri Enhanced Survey (ES). We generated prevalence odds ratios to identify predictors of non-compliance to cervical cancer screening guidelines. Also, among a sample of women reporting a reason for last Pap test, we estimated the relative odds of a screening v. diagnostic exam. Results: In the combined probability sample, compliance with screening schedule was likely among women younger than 50 years of age and women who had either a recent mammography or a clinical breast exam. Being African-American, not experiencing a cost barrier when seeking medical care, having at least a high-school education and health coverage were each associated with an increased compliance with a screening schedule in the combined probability sample. Among women in the combined probability sample, whites, those who experienced no cost barrier to seeking medical care, the non-obese, and those who had a recent mammography were each more likely to have had a screening as opposed to a diagnostic exam. Discussion: Cancer control and cardiovascular (CVD) prevention programs should consider jointly targeting those at high risk for cervical cancer and CVD because of aging and associated high-risk behavior such as non-compliance with cervical cancer screening, smoking, and obesity. Also, further research is needed to examine whether the increased compliance with cervical cancer screening guidelines among African American women may be in part due to higher occurrence of diagnostic Pap smears.     

Cervical cancer screening practices among older women: results from the Maryland Cervical Cancer Case-Control Study

Considerable evidence shows a large proportion of older women have either never had a Pap test or have significant gaps in their history of cervical cancer screening. Differences in health care utilization patterns by age, cohort differences in use of medical subspecialities, and provider reluctance to perform cancer screening within the general medical care encounter have been suggested as reasons for underscreening. Our study conducted in 1985 documents prior health care utilization patterns of 153 cases of Maryland women with invasive cervical cancer compared with a matched control group. Analysis within three age groups showed that cases were significantly less likely to have ever had a Pap test or to receive regular Pap testing, primarily due to differences in medical care utilization patterns. Never having an obstetrician-gynecology visit, a recent (less than 3 years) internist visit, or not having any out-patient visit were significant risk factors. Other risks included older age at first Pap test, reporting not being told to have routine Pap tests, and not using contraceptives. In a multiple logistic regression analysis, recent out-patient visits and lifetime use of an obstetrician-gynecologist remained significant after adjusting for age interactions with recent Pap test history, underscoring the importance of medical care utilization patterns for screening of cancer of the uterine cervix among the elderly.     

Pain predicts non-adherence to pap smear screening among middle-aged African American women

BACKGROUND: Middle-aged African American women have the highest incidence and mortality of invasive cervical cancer in the United States and the lowest adherence to pap smear screening. METHODS: In 2001, we identified factors associated with non-adherence to screening recommendations using three focus group interviews and subsequently developed a questionnaire administered to 144 African American women aged 45 to 65 years. RESULTS: The perception that the Pap test was painful was associated with non-adherence to screening recommendations (OR = 4.78; 95%CI: 1.67-13.7). Difficulty to pay for the office visit coupled with perceived pain was associated with a nearly sixfold increase in risk of non-adherence (OR = 5.8; 95%CI: 2.8-15.5). Previously identified barriers to screening including lower education and socioeconomic status, poor access to care, knowledge of and exposure to known risk factors of invasive cervical cancer, cancer fatalism, and perceived racism were not independently associated with non-adherence. CONCLUSIONS: These data suggest that, among middle-aged African American women, future interventions addressing pain during a Pap test will likely increase acceptability of and adherence to cervical cancer screening. Pain could be addressed either by providing information during the pap test and/or using smaller lubricated speculums.     

Physical Activity and Cervical Cancer Testing Among American Indian Women

Purpose: Studies have shown that women who engage in high levels of physical activity have higher rates of cancer screening, including Papanicalaou (Pap) tests. Because American Indian (AI) women are at high risk for cervical cancer morbidity and mortality, we examined Pap screening prevalence and assessed whether physical activity was associated with screening adherence among AI women from 2 culturally distinct regions in the Northern Plains and the Southwest. Methods: A total of 1,979 AI women at least 18 years of age participating in a cross‐sectional cohort study reported whether they received a Pap test within the previous 3 years. Physical activity level was expressed as total metabolic equivalent (MET) scores and grouped into quartiles. We used binary logistic regression to model the association of Pap testing and MET quartile, adjusting for demographic and health factors. Findings: Overall, 60% of women received a Pap test within the previous 3 years. After controlling for covariates, increased physical activity was associated with higher odds of Pap screening (OR = 1.1 per increase in MET quartile; 95% CI = 1.1, 1.2). Conclusions: This is the first study to examine physical activity patterns and receipt of cancer screening in AIs. While recent Pap testing was more common among physically active AI women, prevalence was still quite low in all subgroups. Efforts are needed to increase awareness of the importance of cervical cancer screening among AI women.     

Pap Smear Screening among Urban Southwestern American Indian Women

Background. American Indian women have among the highest incidence and mortality rates of cervix cancer in the United States. The incidence of cancer of the cervix among American Indians is 19.5/100,000 versus 7.8/100,000 in U.S. whites, and comparison by geographic region/tribe indicates that the rate is four to six times higher in some tribes. Papanicolaou cytological testing (Pap smear) permits the detection of cervical lesions before they become cancerous, effectively reducing the incidence of cervical cancer by 75–90%. The American Cancer Society recommends a Pap smear every year beginning at age 18 years or when sexually active, and more frequent screening in high-risk populations.Methods. A random household cross-sectional survey was conducted in Phoenix, Arizona, to assess cervical cancer screening rates among 519 adult urban American Indian women. Logistic regression was used to identify predictors of Pap smear use.Results. Three-quarters (76.1%) of urban women American Indian surveyed received a Pap smear within the past 3 years, but only 49.5% received a Pap smear within the last year. Women over age 50 years were significantly less likely to have received a recent Pap smear in comparison to younger women.Conclusions. The results of this study indicate that limited access to health care and lack of knowledge about the procedure were important barriers to Pap smear use. Improving cervix cancer screening participation rates is an important step in reducing the disease burden in this high-risk population.     

Correlates of underutilization of gynecological cancer screening among lesbian and heterosexual women

BACKGROUND: Study aims were to examine cervical cancer risk factors, screening patterns, and predictors of screening adherence in demographically similar samples of lesbian (N=550) and heterosexual women (N=279). METHODS: Data are from a multisite survey study of women's health conducted from 1994 to 1996. RESULTS: Differences in sexual behavior risk factors for cervical cancer were observed with lesbians reporting earlier onset of sexual activity (P<0.05), more sexual partners (P<0.001), and lower use of safer sex activities (P<0.01). Lesbian and heterosexual women were equally likely to have ever had a Pap test; however, lesbians were less likely to report annual (P<0.001) or routine (P<0.001) testing. Multivariate analyses were used to determine the associations between demographics, health care factors, health behaviors, and worry about health and screening behaviors. Individual predictors of never screening included younger age, lower income, and lack of annual medical visits. Independent predictors of both recent and annual screenings included history of an abnormal Pap test, being heterosexual, and annual medical visits. CONCLUSION: Data indicate that lesbians are at risk for cervical cancer, yet underutilize recommended screening tests. Findings have implications for research, education, and cancer control among lesbians.     

Differences in Cervical Cancer Screening Between African-American Versus African-Born Black Women in the United States

Although the incidence of cervical cancer has been declining steadily since the Pap smear became standard of care in the U.S., many African immigrants are unfamiliar with this screening test and its potential benefits. Using data from the CDC’s National Health Interview Surveys, we identified respondents who were black women living in the United States, distinguishing U.S.-born (n = 620) and African-born (n = 36). We constructed a measure of current Pap status and used multivariate logistic regression models to compare Pap status between the two groups. Controlling for income, age, education, health insurance, and marital status, African American women were over 3 times more likely to have reported a current Pap smear than African-born women [Adjusted OR = 3.37, 95 % CI = (1.89, 5.96)]. Being an African-born woman was the strongest predictor of current Pap status. Distinguishing immigrant status in an analysis of cervical cancer screening rates for black women indicated much lower Pap smear rates for African-born women, compared with African-American women. More research on the impact of education and culturally specific care is needed to address the disparity in Pap smear rates for African-born black women.     

Breast and cervical cancer screening among low-income women in Nebraska: findings from the Every Woman Matters program, 1993-2004

OBJECTIVE: To examine the likelihood of enrollees in the Nebraska Every Woman Matters program being screened for breast and cervical cancer. METHODS: We explored the relationship between sociodemographic characteristics and receiving cancer screening services. RESULTS: Older and Native American women were more likely than younger and White women to have mammograms ordered [adjusted odds ratio (OR)=1.41, 95% confidence interval (CI) 1.08, 1.85]. African American [OR=0.54, 95% CI 0.46, 0.64] and Native American women [OR=0.47, 95% CI 0.39, 0.55] were less likely than White women to have clinical breast exams performed. Native American [OR=0.19, 95% CI 0.16, 0.23] and African American women [OR=0.56, 95% CI 0.46, 0.68] were less likely than White women to have a Pap test performed. CONCLUSION: Receiving cancer screening services was related to race; thus, understanding barriers for screening for minority women is warranted.     

Breast cancer screening behaviors among African American women with a strong family history of breast cancer

BACKGROUND: Despite the importance of breast cancer screening to reduce morbidity and mortality, limited information is available on screening practices among African American women with a family history that is suggestive of hereditary breast cancer. OBJECTIVES: To describe adherence to breast cancer screening recommendations among African American women with a family history that is suggestive of hereditary disease. METHODS: Participants were unaffected African American women (n=65) who had a family history of cancer that was suggestive of hereditary breast cancer. Breast cancer screening practices were evaluated by self-report. The study was conducted at the University of Pennsylvania in Philadelphia, PA. Women were recruited to participate in the study from February 2003-December 2005. RESULTS: Most women were adherent to recommendations for mammography (75%) and CBE (93%). A sizeable minority of women (41%) also performed excessive BSE. Being older than age 50 was associated significantly with mammography adherence (FET<0.05). Employment had a significant independent association with BSE; unemployed women were most likely to perform excessive BSE (OR=3.28, 95% CI: 1.05, 10.21, p<0.05). CONCLUSIONS: The results of this study suggest a complex pattern of breast cancer screening practices among African American women at increased risk for hereditary breast cancer.     

What Australian women want and when they want it: cervical screening testing preferences,decision‐making styles and information needs

Background New testing technologies and human papillomavirus (HPV) vaccines have recently brought changes to cervical cancer screening. In 2006, the Australian government also changed the protocol for managing abnormal Pap smears. Australian women’s attitudes and preferences to these changes are largely unknown. Quantitative data on information needs and community attitudes to informed decision making in screening in Australia are also limited. Objective This national study measures women’s preferences for testing and management of abnormal screening results, preferred decision‐making styles and information needs for cervical cancer screening. Design A randomly selected sample of Australian women aged 18–70 participated in a structured telephone questionnaire, exploring testing preferences, information and decision‐making needs. Results A total of 1279, of 1571 eligible women, participated in the study with an overall response rate of 81.4%. Half of the women (n = 637) preferred having their Pap smears at least annually, and 85% wanted concurrent HPV testing. A large proportion of women preferred to be involved in decision making for both routine Pap smears (87%) and follow‐up for abnormal results (89%). The majority of women wanted information on screening risks (70%) and benefits (77%); of these 81 (85%) wanted this information before screening. However, 63% of women only wanted information about follow‐up examinations if they had an abnormal Pap test result. Conclusion Australian women want to be involved in decision making for cervical cancer screening and require information on the risks and benefits of Pap testing prior to undergoing any screening.     

Cervical cancer screening beliefs among young Hispanic women

OBJECTIVES: This study examined beliefs, attitudes, and personal characteristics that correlated with self-reported cervical cancer screening history among Hispanic women aged 18 to 25 years old in El Paso, TX, a large metropolitan area on the U.S.-Mexico border. METHODS: Data were collected through a cross-sectional, face-to-face survey. The study questionnaire was based primarily on the Health Belief Model, and included scales that measured perceived susceptibility and seriousness of cervical cancer, and perceived benefits and barriers to Pap test screening. The study questionnaire also included measures of acculturation, Pap test history, pregnancy and sexual history, use of birth control, type of medical insurance, and educational attainment. RESULTS: Sixty-nine percent reported ever having had a Pap test and 56% reported having had a test in the past year. Eighty percent reported that they were sexually active, and of these, 63% reported using birth control. Respondents understood the seriousness of cervical cancer, their susceptibility to cervical cancer, and the benefits of Pap testing; however, only 61% agreed that most young women whom they know have Pap tests. Greater acculturation and the belief that most young unmarried women have Pap tests were positively associated with ever having screening. The perception that the test would be painful and not knowing where to go for the test were negatively associated with ever having a Pap test. CONCLUSIONS: This study found suboptimal rates of screening for cervical cancer in a sample of young Hispanic women residing along the U.S.-Mexico border. Although women may understand the seriousness of cervical cancer and the benefits of screening, perceptions about Pap tests may pose barriers to undergoing screening. Efforts to increase screening also may need to focus specifically on women who are least acculturated, as they also were least likely to have had prior Pap tests.     

Engaging women's interest in colorectal cancer screening: a public health strategy

Screening rates for colorectal cancer are unacceptably low. New guidelines, public education campaigns, and expanded coverage of screening costs by healthcare insurance are expected to increase screening rates, but interventions targeting women may accelerate this change. Most American women already participate in regular cancer screening, in the form of Papanicolaou (Pap) tests and mammography, so they may be receptive to tailored messages about the need to add regular colorectal cancer screening to their preventive health regimen. In addition, their role in promoting the health of family members may position women to influence screening behavior in family and friends. Women may be particularly valuable change agents in populations where screening rates are traditionally low, such as medically underserved populations, the elderly or low socioeconomic status groups with competing health priorities, and populations with cultural values or practices inconsistent with the adoption of a new screening behavior. To serve as agents of change in their family and social networks, women must understand that colorectal cancer is not solely a man's disease and that the benefits of colorectal screening are similar to those of Pap testing and mammography. Colorectal cancer screening should also be promoted within a framework of a lifelong strategy for health maintenance for both men and women. The message to women should emphasize the value of colorectal cancer screening rather than the disagreement among experts over preferred screening strategies and should emphasize the value of shared decision making between the patient and her healthcare provider.     

Pap smear receipt among Vietnamese immigrants: the importance of health care factors

Objective. Recent US data indicate that women of Vietnamese descent have higher cervical cancer incidence rates than women of any other race/ethnicity, and lower levels of Pap testing than white, black, and Latina women. Our objective was to provide information about Pap testing barriers and facilitators that could be used to develop cervical cancer control intervention programs for Vietnamese American women.

Design. We conducted a cross-sectional, community-based survey of Vietnamese immigrants. Our study was conducted in metropolitan Seattle, Washington, DC. A total of 1532 Vietnamese American women participated in the study. Demographic, health care, and knowledge/belief items associated with previous cervical cancer screening participation (ever screened and screened according to interval screening guidelines) were examined.

Results. Eighty-one percentage of the respondents had been screened for cervical cancer in the previous three years. Recent Pap testing was strongly associated (p<0.001) with having a regular doctor, having a physical in the last year, previous physician recommendation for testing, and having asked a physician for testing. Women whose regular doctor was a Vietnamese man were no more likely to have received a recent Pap smear than those with no regular doctor.

Conclusion. Our findings indicate that cervical cancer screening disparities between Vietnamese and other racial/ethnic groups are decreasing. Efforts to further increase Pap smear receipt in Vietnamese American communities should enable women without a source of health care to find a regular provider. Additionally, intervention programs should improve patient–provider communication by encouraging health care providers (especially male Vietnamese physicians serving women living in ethnic enclaves) to recommend Pap testing, as well as by empowering Vietnamese women to specifically ask their physicians for Pap testing.     

Young Asian Americans’ Knowledge and Perceptions of Cervical Cancer and the Human Papillomavirus

Cervical cancer is a major health disparity among Asian Americans, with cervical cancer rates of Vietnamese women being significantly higher than for the general US female population and low screening rates reported for Asian American females. Focus groups and interviews were conducted with young Vietnamese, Filipino, and Korean adults (ages 18–29) to collect information on knowledge, perceptions and sources of information regarding cervical cancer, Pap tests and the human papillomavirus. 16 Korean, 18 Vietnamese, and 18 Filipino (50% female) adults participated in the study. Many participants had never heard of HPV, cervical cancer and Pap testing. Cervical cancer screening rates were low for Korean and Vietnamese females and were influenced by moral beliefs and lack of awareness. Culturally relevant education materials that consider specific Asian ethnicity and language are needed to increase awareness of cervical cancer, Pap testing, and HPV among Asian American young adults     

Cervical Cancer among Asian American Women: A Neglected Publica Health Problem?

PURPOSE OF THE PAPER: Relatively little attention has been paid to cervical cancer control in Asian American populations. We summarize available cervical cancer incidence and mortality dat, present information on levels of Pap testing use, and review factors that may be associated with cervical cancer screening participation. METHODS: We reviewed the literature pertaining to cervical cancer and Pap testing among Asian populations in North America. PRINCIPAL FINDINGS: Cancer registry data suggest that women from Southease Asia have a nearly five­fold increased risk of invasive cervical cancer (when compared to non­Hispanic White women). Filipino and Korean populations also have elevated risks. The excess invasive cervical cancer burden appears to be concentrated among women aged 40 and older. Pap testing use by Asians is less than for all toher racial/ethnic groups in the U.S., and recent studies suggest that over one­third of Vietnamese immigrants have never been screened. Barriers to Pap testing participation by less acculturated Asian women include a lack of familiarity with Western preventive concepts, a lack of knowledge concerning cervical cancer, embarrassment in association with gynecologic exams, the role of women in some Asian cultures, the cost of health care, and language difficulties. CONCLUSIONS: There is a considerable need for ethnoculturally appropriate cervical cancer control programs targeting Asian American populations. RELEVANCE TO ASIAN PACIFIC ISLANDER AMERICAN POPULATIONS: This paper is relevant to Asian American women from East, South, Southeast, and Island Asia.     

BMI and cervical cancer screening among white, African-American, and Hispanic women in the United States

OBJECTIVES: We examined cervical cancer screening by BMI in white, African-American, and Hispanic women and explored women's reasons for not undergoing screening. RESEARCH METHODS AND PROCEDURES: We used logistic regression to examine Pap testing in the preceding 3 years across BMI groups for white (n = 6419), African-American (n = 1715), and Hispanic women (n = 1859) age 18 to 75 years who responded to the 2000 National Health Interview Survey. We used bivariable analyses to describe women's reasons for not undergoing testing and examined whether unscreened women received physician recommendations for screening. RESULTS: Of 12,170 women, 50% were normal weight, 26% were overweight, and 21% were obese. The proportion who reported Pap testing in the last 3 years was 86% in whites, 88% in African Americans, and 78% in Hispanics. After adjustment for sociodemographics, health care access, and illness burden, severely obese white women (BMI = 40+ kg/m2) were significantly less likely to undergo Pap testing (relative risk, 0.92; 95% CI, 0.83 to 0.99) compared with normal weight women. BMI was not associated with screening in African Americans or Hispanics. A higher proportion of obese white women than normal weight women cited putting off the test or embarrassment or discomfort as the primary reason for not undergoing screening. Among the unscreened, obese women were as likely as normal weight women to receive a physician recommendation to undergo screening. DISCUSSION: Disparities in cervical cancer screening by body weight persist for white women with severe obesity. Disparities were not explained by differences in the rate of physician recommendations for screening, but obese white women may be more likely to delay screening or to find screening painful, uncomfortable, or embarrassing than normal weight white women. Efforts to increase screening among obese women should address women's reservations about screening.     

Cancer screening among jail inmates: frequency, knowledge, and willingness

OBJECTIVES: We determined jail inmates' knowledge of cancer screening tests, their frequency of screening, and their willingness to undergo screening in jail in order to assess preventive health services for jail inmates. METHODS: We performed a cross-sectional interview survey of random samples of county jail inmates (n=133). RESULTS: Approximately half (53%) the participants were African American, 17% were White, 11% were Latino, and 9% reported multiple ethnicities. Among women aged 18 years and older, 90% had had a Papanicolaou (Pap) test within 3 years, and 94% were willing to be screened in jail. Having ever had a Pap test while incarcerated was significantly associated with being up to date on cervical cancer screening. For women aged 40 years and older, 41% reported having had a mammogram within 2 years, and 88% were willing to have one. Among men (n=51) and women (n=4) aged 50 years and older, 25% had knowledge of colon cancer screening, 31% were up to date, and 69% were willing to be screened. Increased knowledge about colon cancer screening was significantly associated with being White and having insurance. Jail inmates, particularly African Americans, had significantly lower frequency of sigmoidoscopy and colonoscopy than the general population. CONCLUSIONS: Jail could be an appropriate venue in which to provide cancer screening for a high-risk population. Inmates were receptive to jail-based screening.     

Race and Ethnic Disparities in Cervical Cancer Screening in a Safety-Net System

Objectives: The three objectives of this research were: 1) to examine the use of Pap smear tests among low-income women, including minority and immigrant women who were patients in a safety-net healthcare system; 2) to identify policy relevant variables that could lead to changes in use of Pap smear screening services for these women; and 3) to contribute to the literature on use of Pap smear screening, especially among minorities and immigrants. The Behavioral Model for Vulnerable Populations was used as the theoretical framework. Methods: Pap smear screening predictors were examined using telephone interviews with a random sample of women aged 18–60, including 465 Non-Hispanic Whites, 285 African Americans, 164 Hispanic Americans, and 256 Hispanic immigrants, enrolled in a safety-net healthcare system in Texas in Fall 2000. Binary logistic regression analysis was used. Results: The research revealed that Non-Hispanic Whites were most likely to have been screened ever and in the past 3 years, followed by African Americans, Hispanic immigrants, and Hispanic Americans. Among Hispanics, immigrants were most likely to have had Pap smear screening, supporting the “healthy immigrant hypothesis.” Older women were most likely to have ever been screened, with younger women, most likely in the past year. Having a usual source of healthcare and a checkup for current pregnancy increased screening, while competing needs (food, clothing, housing) affected screening negatively. Conclusions: Culturally competent, community-based care for women is needed to increase Pap smear screening among minority groups, especially Hispanic immigrant and Hispanic American women.
