Cervical cancer screening among Latinas recently immigrated to the United States

BACKGROUND: Little is known about the cancer screening practices of women whose behavior may place them at a high risk for cervical cancer. We explored factors that influence repeated Pap smear screening among recently immigrated Latinas working in bars also called cantinas. METHODS: Face-to-face interview were administered to 360 women working in 60 cantinas. Participants provided information about their cancer screening practices including the number of Pap smears completed in the 5 years before the interview. A theory-based model proposing that demographic characteristics, cancer screening barriers and facilitators, and psychosocial factors influence repeated Pap smear screening was tested with a hierarchical linear regression. RESULTS: Facilitators of cancer screening (recent visit to a physician and receiving a Pap smear in a clinic) and psychosocial variables (Pap smear beliefs, cancer screening intentions and lack of encouragement) were significantly associated with the total number reported Pap smears (adjusted R2 = 0.31, P < 0.0001). Cervical cancer risk behaviors were not significantly associated with repeated screening. CONCLUSIONS: While risk behaviors did not act as barriers, access to health care measures facilitated repeated Pap smear screening. Psychosocial factors hypothesized to function as antecedents of Pap smear screening appear instead to follow from repeated experience with the examination.     

Health beliefs and Pap smears among Thai women in Brisbane,Australia

Although a number of studies have assessed the use of Pap smear among Thai women in Thailand, little is known about factors influencing the use of this cervical cancer screening among potentially high risk Thai migrant women. We related health belief model (HBM) factors and sociodemographic variables to the use of Pap smears among migrant Thai women in Brisbane, Australia. A cross-sectional study was conducted in Brisbane, Queensland, Australia. A snowball sampling method was used to recruit 145 women. Thirty-nine percent reported regular Pap smears. Summary HBM index and self-efficacy index were positively associated with Pap smears. Barriers to screening were negatively associated. The HBM appears to be a useful framework for planning cervical cancer prevention. Strategies that reduce barriers to the screening and increase the confidence of women and their self-efficacy are likely to increase their participation.     

Low knowledge of cervical cancer and cervical pap smears among women in Peru, and their ideas of how this could be improved

Estimates of the percentage of women who have had Pap smears in Peru vary between 7% and 43%. This study explores what women know about cervical cancer and Pap smears, as well as their barriers to obtaining Pap smears. Focus group discussions (FGD) were conducted with a total of 177 women in four Peruvian cities. Discussions reveal that most women did not know what causes cervical cancer. Most women did not know the purpose of Pap smears, although knowledge about Pap smears was higher than knowledge about cervical cancer. Fear, embarrassment, and lack of knowledge were the main barriers identified for not getting Pap smears. Programs and policies aiming to increase Pap smear coverage must start by educating women on cervical cancer and its prevention in order to improve women's perceptions about the screening test and increase Pap smear seeking behaviors in the long term.     

Cervical cancer screening: who is not screened and why?

BACKGROUND: The decline in death rates from cervical cancer in the United States has been widely attributed to the use of Papanicolaou (Pap) smears for early detection of cervical cancer. METHODS: Pap smear screening rates, beliefs about appropriate screening intervals and factors affecting screening were examined using 1987 National Health Interview Survey data. RESULTS: Results indicate that through age 69, Blacks are screened at similar or higher rates than Whites. Hispanics, particularly those speaking only or mostly Spanish, are least likely to have received a Pap smear within the last three years. Of women who had never heard of or never had a Pap smear, nearly 80 percent reported contact with a medical practitioner in the past two years, while more than 90 percent reported a contact in the past five years. Overall, the most frequently reported reason for not having a recent Pap smear was procrastinating or not believing it was necessary. CONCLUSIONS: Thus, in developing screening programs, Hispanics, particularly Spanish speakers, must be targeted. In addition, educational programs should target unscreened women who forego the test due to underestimating its importance, procrastination, or because their medical care provider did not suggest the procedure. Women must be intensively educated that Pap smears should be scheduled routinely to detect asymptomatic cervical cancer.     

Perceptions of cervical cancer threat, benefits, and barriers of Papanicolaou smear screening programs for women in Iran

OBJECTIVES: The main purpose was to assess associations between HBM variables and participation in cervical cancer screening programs in a sample of Iranian women. METHODS: A total of 333 married women of childbearing age were recruited with cluster sampling. The study was conducted from spring 2002 to spring 2003 and a self-report questionnaire and structured interview were designed to measure the four HBM constructs and Iranian women's knowledge about Pap smear screening. RESULTS: A total of 68.5% reported having undergone at least one Pap test. Women were more likely to participate in Pap smears when they had access to knowledge about cervical cancer and screening programs. Furthermore, the perceived benefit and barrier variables of the Health belief model were two factors related to participation in Pap smear testing. CONCLUSIONS: Health care professionals must provide women with more information about cervical cancer and the benefits of participating in cervical cancer screening programs.     

Pap smear use in California: are we closing the racial/ethnic gap?

BACKGROUND: Minority women continue to be disproportionately affected by cervical cancer. Minority population groups at high risk for cervical cancer may be failing to fully comply with screening recommendations. The use of Pap smears among women in California was evaluated to identify ethnic groups at higher risk for noncompliance with cervical cancer screening. METHODS: Cross-sectional analysis of 2001 California Health Interview Survey data. Logistic regression was used to assess the independent contribution of race/ethnicity to the use of Pap smears. RESULTS: Hispanic (aPR = 1.03, 95% CI 1.02-1.05) and Black (aPR = 1.03, 95% CI 1.001-1.06) women are more likely to report a Pap smear in the past 3 years as compared to White women. Asians were the least likely to report cervical cancer screening despite a more favorable sociodemographic profile. Screening rates varied among Hispanic or Asian subgroups; Mexicans, Vietnamese, Chinese, and South Asians are particularly underserved. CONCLUSIONS: In contrast to the country as a whole, Hispanic women in California are more likely to report a recent Pap smear as compared to White women. However, racial/ethnic disparities in Pap smear use persist; Asian women are the least likely to report cervical cancer screening as compared to any other group.     

Papanicolaou smear: can we make a good test better? Technical and interpretive challenges for the practitioner

The Papanicolaou smear has proven to be an excellent screening test for cervical cancer and has resulted in a significant decrease in mortality from invasive cervical cancer. A relatively high false-negative rate of Pap smears might cause failure to diagnose preinvasive disease, especially when coupled with an increased screening interval. This review focuses on the causes of and methods to reduce the number of false-negative Pap smears. In addition, we address the clinical significance of ambiguous Pap smear diagnoses, such as atypical squamous/glandular cells of undetermined significance, and suggest a scheme for management of patients with these diagnoses. Although efforts to reduce false-negative Pap smears are important, the most effective way of reducing mortality from invasive cervical cancer is universal, organized, population-based screening of all women.     

Limited Pap screening associated with reduced risk of cervical cancer in South Africa

BACKGROUND: We investigated the effect of Pap smear screening on the incidence of invasive cancer of the cervix in the Western Cape, South Africa where screening is limited. METHODS: Data were derived from a case-control study of the association of hormonal contraceptives and invasive cervical cancer. Incident cases (n = 524) of invasive cervical cancer who presented at two tertiary hospitals and controls (n = 1540) series matched for age, race, and place of residence were interviewed. Information on a wide range of variables was collected including whether the women had previously had a Pap smear taken and the number and timing of smears. Odds ratios (OR) and 95% CI were calculated using multiple logistic regression. RESULTS: The OR of cervical cancer was reduced among women who had ever had a smear (OR = 0.3, 95% CI: 0.3-0.4). The OR declined with increasing number of smears to 0.2 for >/=>3 smears (trend P = 0.0003). Among women who had a smear <5 years previously the OR was 0.3, but even if the smear was taken >/=15 years previously the women remained at reduced risk (OR = 0.5). CONCLUSION: The data suggest that even limited Pap smear screening reduces the risk of cervical cancer. Should a screening programme be successfully implemented, the incidence of cervical cancer might be reduced by as much as 70%.     

Hispanic acculturation and utilization of cervical cancer screening in the US

BACKGROUND: Hispanic women have an incidence rate of invasive cervical cancer that is twice as high as that of non-Hispanic White women. Previous investigations have reported that Hispanics are less likely to utilize cancer screening services. Using data from the 2000 National Health Interview Survey, this study examined whether acculturation of Hispanic women was associated with cervical cancer screening. METHODS: The subjects included 2307 Hispanic women aged 21-70 who did not have a history of cervical cancer or a hysterectomy. Women were analyzed by acculturation level according to whether or not they ever had a Pap smear and had one in the previous year and previous 3 years. RESULTS: Acculturation levels tended to be inversely correlated with no Pap smear. Compared to lower acculturated women, women who were more acculturated were less likely to never had a Pap smear (OR = 0.86; 95% CI = 0.58-1.27 for moderate acculturated women and OR = 0.51; 95% CI = 0.29-0.89 for higher acculturated women). Similar results were found for having no Pap smear within the past 3 years (OR = 0.83; 95% CI = 0.61-1.13 for moderate acculturated women and OR = 0.73; 95% CI = 0.49-1.08 for higher acculturated women). CONCLUSION: The findings show that lower acculturation was associated with the under use of cervical cancer screening and suggest that these women might have barriers in accessing and utilizing Pap smears.     

Relationship between Pap smear performance and physician ordering a mammogram.

BACKGROUND. Although Pap smear screening for cervical cancer in general has been successfully implemented, mammography screening for breast cancer remains relatively underused. Patients having one screening test are more likely to have other screening tests performed. The objective of this study was to determine whether visits by women for Pap smears serve as opportunities for physicians to order a screening mammogram. METHODS. A matched case-control design was used for this retrospective study. Eligible women included those over 50 years of age who had no history of breast cancer or mastectomy and who had made at least one visit to a family practice residency program during the 2-year study period. Cases were randomly selected from women who had mammograms performed. For each case, one control subject who did not have a mammogram was matched by age and number of visits. A chart audit was performed to collect data on the characteristics of these women and whether they completed their screening tests. RESULTS. The adjusted odds ratio (controlling for the patient's age and number of physician visits) for mammogram completion among women who had a Pap smear compared with those who did not was 6.67. This effect persisted after controlling for other confounding factors using logistic regression. CONCLUSIONS. Performing a Pap smear appears to serve as a prompt for the physician to order a screening mammogram. That physicians appear to provide screening tests, particularly Pap smears and mammograms, as a package of services should be considered when future efforts to improve implementation are made.     

Repeated Pap smear screening among Mexican-American women

The factors that influence repeated cervical cancer screening among Latina women are not well understood. Studies of compliance in this population over-emphasize initial or recent screening and under-emphasize how this practice is repeated over time. The purpose of this study was to identify the demographic and psychosocial factors associated with repeated Pap smear screening among low-income Mexican-American women living in two urban communities in Texas. A total of 1804 Mexican-American women were interviewed as part of a community survey. Multiple regression results indicate that demographic characteristics such as age, marital status, level of acculturation and health insurance were associated with the total number of Pap smears reported for the 5 years prior to the interview. Pap smear beliefs were the strongest predictor of repeated screening, while global beliefs about cancer did not significantly explain the results. Health promotion interventions should take into consideration the cultural and psychosocial needs of Mexican-American women, placing emphasis on their specific screening-related beliefs, if they are to succeed in promoting repeated compliance with Pap smear screening guidelines.     

Inadequacy of cervical cancer screening among urban recent immigrants: a population-based study of physician and laboratory claims in Toronto, Canada

OBJECTIVE: In Canada, Pap smears are recommended from 18 to 69. Self-reported socioeconomic gradients in screening have been documented in North America but there have been few direct measures of Pap smear use among immigrants or socially disadvantaged groups. Our purpose was to investigate whether socioedemographic factors are related to cervical cancer screening in Toronto, Canada. METHOD: Pap smears were identified using fee and laboratory codes in Ontario physician service claims for 3 years (2000-2002 inclusive) for women aged 18-66. Area-level socioeconomic factors were derived from the 2001 census. At the individual level, recent registrants for health coverage, over 80% of whom are expected to be recent immigrants, were identified as women first registering after January 1, 1993. RESULTS: Among 724,584 women, 55.4% had Pap smears within 3 years. Recent immigration, visible minority, foreign language, low income and low education were all associated with significantly lower area rates. Recent registrants had much lower rates than non-recent registrants (36.9% versus 60.9%). CONCLUSION: Pap smear rates in Toronto fall below those dictated by evidence-based practice. Recent registrants, a largely immigrant group, have particularly low rates. Efforts to improve coverage need to emphasize women who recently immigrated and those with socioeconomic disadvantage.     

Incidence of cervical cancer following negative smear. A cohort study from Maribo County, Denmark

In order to estimate the risk of developing cervical cancer among women who originally had cytologically normal Papanicolaou (Pap) smears, information has been collected on all Pap smears taken in Maribo County, Denmark in 1966-1982 among women born 1918-1952. A total of 27,811 women are included in the study, and cases of invasive cervical cancer developed in the study population have been identified from the local department of pathology and from the Danish Cancer Registry. The incidence of cervical cancer has been tabulated by number of previous negative smears and by time elapsed since last negative smear. Women with one previous negative smear have a zero risk of developing cervical cancer during the first year following the negative smear. The incidence among these women increases with length of time since the negative smear and reaches the level of unscreened women during the fifth year of follow-up. Women with 2-4 previous negative smears also have a negligible risk of developing cervical cancer during the first two years following the last negative smear. The incidence among these women increases less over time than the incidence for women with one previous negative smear. No cases of cervical cancer were observed among 7,716 women with 5+ previous negative smears. The study indicates that the 5-year risk of developing cervical cancer is 48% lower in women with one previous negative smear than in an unselected population of unscreened women. The 5-year risk for women with 2-4 previous negative smears is 69% lower than that for unscreened women.     

Sociodemographic factors of Pap smear screening in Taiwan

Substantial evidence exists that regular screening is effective in preventing cervical cancer. However, the existing services are underused by many women in Taiwan. To examine the effects of sociodemographic characteristics on the underuse of Papanicolaou (Pap) smear screening, from September to December 1993 we conducted a questionnaire interview on a sample of 4,400 women aged 20 years and older in Taipei city using multistage sampling with probability proportional to size. Our results indicate that 40% of the women sampled have never had a Pap smear and 86% have not had one in the past year. Age is the strongest factor affecting Pap smear use, particularly for women below age 30 and over the age of 65. In addition, women with lower levels of education, women who are not employed, never-married women who live outside the city tend to underuse Pap smear screening. These findings help indicate priority groups which should be targeted to increase screening and consequently reduce cervical cancer. Our data also provides a good baseline for comparison of rates of Pap smear screening by various sociodemographic factors in the future.     

Perceptions of Cervical Cancer Threat,Benefits, and Barriers of Papanicolaou Smear Screening Programs for Women in Iran

ABSTRACT

Objectives: The main purpose was to assess associations between HBM variables and participation in cervical cancer screening programs in a sample of Iranian women.

Methods: A total of 333 married women of childbearing age were recruited with cluster sampling. The study was conducted from spring 2002 to spring 2003 and a self-report questionnaire and structured interview were designed to measure the four HBM constructs and Iranian women's knowledge about Pap smear screening.

Results: A total of 68.5% reported having undergone at least one Pap test. Women were more likely to participate in Pap smears when they had access to knowledge about cervical cancer and screening programs. Furthermore, the perceived benefit and barrier variables of the Health belief model were two factors related to participation in Pap smear testing.

Conclusions: Health care professionals must provide women with more information about cervical cancer and the benefits of participating in cervical cancer screening programs.     

Cancer screening behaviors among U.S. women: breast cancer, 1987-1989, and cervical cancer, 1988-1989.

Data from the Behavioral Risk Factor Surveillance System (BRFSS) were used to examine trends in breast and cervical cancer screening behaviors among U.S. women in selected states. Data reported are from the 1987, 1988, and 1989 BRFSS for breast cancer screening (mammography) and from the 1988 and 1989 BRFSS for cervical cancer screening (Papanicolaou [Pap] smear). Results are presented as either state-specific or state-aggregate data for the years noted above. State-specific analyses indicated that self-reported mammography utilization increased between 1987 and 1989. Although whites and blacks reported similar mammography utilization rates both for screening and for a current or previous breast problem, disparities were evident among women of different ages and incomes. The proportion of women who reported ever having had a Pap smear and having heard of a Pap smear were extremely high and remained fairly consistent across the 2 survey years. State-aggregate analyses, however, showed that the percentage of women who had had a Pap smear within the previous year was negatively associated with age and positively associated with income. A higher proportion of blacks than whites obtained Pap smears. These results indicate that certain segments of the population are not taking full advantage of available breast and cervical cancer screening technologies. Public health strategies, such as those outlined in the Breast and Cervical Cancer Mortality Prevention Act of 1990 (Public Law 101-354), should enhance screening opportunities for these women.     

Agreement between patient self-reports and medical records for Pap smear histories.

As part of a larger cervical cancer study, we tried to verify the Pap smear histories for 125 black women with cervical cancer. For 105 of the patients, we identified all possible providers for the five-year period before the calendar year of diagnosis. Agreement between the medical records and the patient reports was poor to fair (kappa = 0.34) for whether the patient had a Pap smear in the three-year period before diagnosis. Patients tended to report far more Pap smears than medical records confirmed. Important determinants of agreement were the number of Pap smears reported during the five-year period and the age of the patient. The older the patient and the more Pap smears reported, the larger the discrepancy between the medical record and her self-report. The medical records did not contain enough data for us to complete an investigation of the possible reasons for this disagreement. Our results suggest these implications: (1) clinicians should strongly consider performing Pap smears if they doubt a patient's screening history, and (2) Pap smear registries are required for reliable and efficient evaluations of cervical cancer control programs because neither the patient report nor medical records are adequate.     

Cancer screening in women: body mass index and adherence to physician recommendations

BACKGROUND: The reasons that obese women are less likely to obtain mammograms and Papanicolaou tests (Pap smears) are poorly understood. This study evaluated associations between body mass index (BMI) and receipt of and adherence to physician recommendations for mammography and Pap smear. METHODS: Data from the 2000 National Health Interview Survey (8289 women aged 40 to 74 years) were analyzed in 2006 using logistic regression. Women with previous hysterectomy were excluded from Pap smear analyses (n=5521). Outcome measures were being up-to-date with screening, receipt of physician recommendations, and women's adherence to physician recommendations for mammography and Pap smear. RESULTS: After adjusting for sociodemographic variables, healthcare access, health behaviors, and comorbidity, severely obese women (BMI > 40 kg/m(2)) were less likely to have had mammography within 2 years (odds ratio [OR]=0.50, 95% confidence interval [CI]=0.37-0.68) and a Pap smear within 3 years (OR=0.43, 95% CI=0.27-0.70). Obese women were as likely as normal-weight women to receive physician recommendations for mammography and Pap smear. Severely obese women were less likely to adhere to physician recommendations for mammography (OR=0.49, 95% CI=0.32-0.76). Women in all obese categories (BMI > 30 kg/m(2)) were less likely to adhere to physician recommendations for Pap smear (ORs ranged from 0.17 to 0.28, p<0.001). CONCLUSIONS: Obese women are less likely to adhere to physician recommendations for breast and cervical cancer screening. Interventions focusing solely on increasing physician recommendations for mammography and Pap smears will probably be insufficient for obese women. Additional strategies are needed to make cancer screening more acceptable for this high-risk group.     

Relative and attributable risk for cervical cancer: a comparative study in the United States and Italy

The attributable risk for invasive cervical cancer in the US and Italian populations has been estimated in relation to main 'aetiological' factors (number of sexual partners, age at first intercourse, parity, oral contraceptive use and smoking) and history of Pap smear using data from two case-control studies conducted in the US (466 cases and 788 controls) and Italy (528 cases and 456 controls). The risk of cervical cancer increased in both studies with multiple sexual partners, decreasing age at first intercourse, higher parity, oral contraceptive use and smoking. Levels of exposure to various risk factors were markedly different in the two countries (ie number of sexual partners, frequency of oral contraceptive use and smoking were greater in the US). Multiple Pap smears and a short interval since last Pap smear strongly reduced risk of cervical cancer in both populations, although screening was much more widespread in the US study population, with only 9% of controls reporting no previous smear versus 38% of the Italian control series. The combined population attributable risk for the five 'aetiological' risk factors was slightly greater in the US study (76%) than in the Italian one (69%), chiefly because of a higher prevalence of exposure to sexual factors in US study women. A substantially larger proportion of Italian cases were due in part to deficiency in screening (46% in US and 84% in Italy). Thus, further inclusion of the effect of screening programmes (number of Pap smears and time since last Pap) led to an overall proportion of cases attributable to the examined risk factors of 87% in the US and 95% in Italy.     

PAP SMEAR USAGE IN NEW SOUTH WALES - IMPACT OF ACTIVE PROMOTION

Less than 25 per cent of eligible Australian women have cervical (‘Pap’) smear tests in any year. Rates are particularly low (<8%) for women over 55 years, the group at highest risk of cervical cancer. A regional program, actively promoting Pap smears by widespread direct community intervention and attention to service needs, targeting women over 55 years and under 25 years, was conducted on the North Coast (population 132,000 women) immediately after a New South Wales State-wide media campaign in February 1988. The number of Pap smears done in the region increased 119 per cent for women over 55 years and 44 per cent for 15–24 year-olds during the promotion (63% overall) compared to New South Wales increases of 58 per cent for women over 55 years and 23 per cent for 15–24 year-olds (31% overall). Differences between the North Coast and New South Wales were statistically significant for all age groups in March and in April for women over 55 years. Differences between New South Wales and Australia (no active promotion) were significant for women over 55 years in March and April. Records from a sample of 152 women attending clinics during the campaign showed 63 per cent had not had a smear test for three or more years, 10 per cent never. The results indicate that an intensive, low-cost public health program, working in conjunction with general practitioners, can be effective in increasing smear rates and that well-designed strategies will have an impact on older women, a high risk group who traditionally are poor users of Pap smear services. The combined impact of the two campaign strategies on Pap smear usage was significantly greater than media alone. A Central New South Wales cervical screening database is essential for evaluation of screening promotion.
