Castanon A, Kamineni A, Elfström KM, Lim AWW, Sasieni P. Exposure Definition in Case-Control Studies of Cervical Cancer Screening: A Systematic Literature Review. Cancer Epidemiol Biomarkers Prev 2021; 30:2154-2166. [PMID: 34526301 PMCID: PMC8643309 DOI: 10.1158/1055-9965.epi-21-0376] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 06/14/2021] [Accepted: 09/08/2021] [Indexed: 01/07/2023] Open
Abstract
The first step in evaluating the effectiveness of cervical screening is defining exposure to screening. Our aim was to describe the spectrum of screening exposure definitions used in studies of the effectiveness of cervical screening. This systematic review included case-control studies in a population-based screening setting. Outcome was incidence of cervical cancer. Three electronic databases were searched from January 1, 2012 to December 6, 2018. Articles prior to 2012 were identified from a previous review. The qualitative synthesis focused on describing screening exposure definitions reported in the literature and the methodologic differences that could have an impact on the association between screening and cervical cancer. Forty-one case-control studies were included. Six screening exposure definitions were identified. Cervical cancer risk on average decreased by 66% when screening exposure was defined as ever tested, by 77% by time since last negative test, and by 79% after two or more previous tests. Methodologic differences included composition of the reference group and whether diagnostic and/or symptomatic tests were excluded from the analysis. Consensus guidelines to standardize exposure definitions are needed to ensure evaluations of cervical cancer screening can accurately measure the impact of transitioning from cytology to human papillomavirus-based screening and to allow comparisons between programs.

Preston SM, Darrow WW. Are Men Being Left Behind (Or Catching Up)? Differences in HPV Awareness, Knowledge, and Attitudes Between Diverse College Men and Women. Am J Mens Health 2019; 13:1557988319883776. [PMID: 31787066 PMCID: PMC6887835 DOI: 10.1177/1557988319883776] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Revised: 09/26/2019] [Accepted: 09/27/2019] [Indexed: 11/21/2022] Open
Abstract
The aim of this cross-sectional survey was to assess awareness, knowledge, and attitudes in regard to human papillomavirus (HPV) and vaccination against HPV among college students. From 2015 to 2017, 386 diverse undergraduates were recruited from a south Florida university. A survey, part of which was researcher developed, of HPV awareness, knowledge, and attitudes was conducted. The majority (84%) of participants had heard of HPV, and 70% had favorable attitudes toward vaccination. Only 28% of men and 55% of women had received ≥1 dose vaccine (p = .01), and 4% of all participants reported that they had received 3 doses. Those with ≥1 dose (n = 123, 40.1%) were more knowledgeable about HPV (p = .01). High knowledge scores were recorded for 30% of respondents and were strongly associated with HPV vaccine initiation among both men and women (p < .001) and perceived knowledge among women only (p < .001). Negative attitudes toward HPV vaccine acceptance were associated with low knowledge scores (p = .01) and undervaccination (p < .001). Vaccinated women (n = 95) were over seven times more likely than were unvaccinated women (n = 115) to report positive vaccine attitudes (relative risk = 7.1). HPV vaccination status was not associated with vaccine attitudes among men. HPV knowledge and vaccine uptake remain problematic among college students, and deficits in both are associated with negative HPV vaccine attitudes. Although the knowledge gap is narrowing, HPV vaccination efforts should target young men, as HPV-related cancer morbidity continues to rise in men.

Abstract
The characteristics of women reporting cervical cytology screening has been evaluated using data from control subjects collected in the framework of a case-control study on invasive cervical cancer conducted since 1981 in the greater Milan area. A total of 515 women admitted for nonneoplastic, non-gynecologic, nonendocrine-related acute conditions to a network of general and university hospitals were interviewed. The frequency of cervical screening utilization decreased with age: regular screening (≥ 3 lifetime Pap smears) was reported by 46% of women aged 44 years or less, but only 11% of those aged 65 or more. Married women reported about 50% more frequently occasional (1 or 2) and about three times regular (≥ 3) cervical screening than unmarried ones. Parous women were more frequently screened, but no trend emerged with number of births. Similarly number of medical consultations in the year before the interview was associated with an increased number of Pap smears. There was no consistent association between number or recency of Pap smears and smoking, sexual habits or education, but women in low social classes tended to be less frequently screened. Ever contraceptive users (oral contraceptives or barrier methods) reported an increased probability to be screened regularly and within two years before the interview.

Abstract
Background Use of the Pap test has resulted in a decline in cervical cancer mortality in developed countries. Yet, despite established cervical cancer screening programs, a significant portion of Jamaican women are not undergoing screening for cervical cancer. This study was carried out to identify factors that affect Jamaican women's decisions to screen for cervical cancer. Methods A population survey was administered to 367 clinic-attending women 25 to 54 years of age in the Parish of Trelawny from May to July of 2005. An interviewer-administered questionnaire assessed the women's knowledge, attitudes, and practices regarding cervical cancer and cervical cancer screening. Results Overall, 11% of the women had never had a Pap smear and only 38% had a Pap test within the last year. Annual visits to a health provider have a strong influence on women's decisions to regularly screen for cervical cancer. Provider recommendation also positively affected initial receipt of a Pap smear as well as continued regular screening. Conclusions Programs that promote annual health checkups, encourage consistent provider recommendations, and emphasize screening as a preventive measure might positively influence women's decisions to screen for cervical cancer.

Abstract
OBJECTIVES The objectives of this study were to determine the prevalence and predictors of Pap smear screening among women aged 50 years and older. STUDY DESIGN This cross-sectional study was conducted at two large urban health centres in Selangor. A total of 515 women aged 50 and older were recruited. RESULTS The mean age of the respondents was 58.83±7.05, with a range of 50- 83 years. The prevalence of Pap smear screening was 39.22% (n=202). From the multivariate analysis, Pap smear screening was significantly associated with health care provider advice (adjusted odds ratio (AOR)=18.75; 95% CI=8.30, 42.37); tertiary (AOR=11.26; 95% CI=1.50, 84.68) and secondary education level (AOR=9.47; 95% CI=1.43, 62.84); use of contraception (AOR=2.90; 95% CI=1.48, 5.69); heart disease (AOR=0.22; 95% CI=0.05, 0.97); and worry about Pap smear results (AOR=0.20; 95% CI=0.09, 0.42). CONCLUSION The prevalence of Pap smear screening in the older women is unsatisfactory. Health care provider advice, education level, use of contraception, heart disease and worry about Pap smear results were predictors of undergoing Pap smear screening in this study population.

Abstract
Women need to practice cervical screening regularly to reduce morbidity and mortality. The purpose of this study was to examine the impact of an intervention program on knowledge, attitude, and practice of cervical screening in the population of Lebanese/Armenian women. The design was a cross-sectional, quasi-experimental posttest survey following a yearlong intervention program. The sample included 176 women, who were members of the Armenian Relief Cross in Lebanon. Interventions consisted of educational classes, media messages, and free screening. The instrument was a self-administered questionnaire. Knowledge of women with intervention was higher (p > .05) and practice rate increased between intervention and comparison groups. No difference in attitude was noted. The study was successful in raising awareness and increasing screening in the sample. It is recommended to continue helping women to overcome barriers for cervical screening.

Abstract
BACKGROUND Cervical screening consumes substantial resources, but little is known about utilization in the United States or compliance with guideline recommendations. METHODS To describe population screening coverage, utilization, and outcomes and examine time trends from 2008 to 2011, cervical cytology reports from women residing in New Mexico (981,063 tests from 511,381 women) were evaluated. RESULTS From 2008 to 2011 cervical screening utilization decreased at all ages, but especially in younger women, with a two-third reduction at ages 15 to 20 years. Ninety-four percent of women ages 25 to 29 years were screened within 48 months but coverage decreased at older ages to 69% at 45 to 49 years and 55% at 60 to 64 years. Intervals between screening tests were significantly longer in 2011 compared with 2008 [HR = 1.23; 95% confidence intervals (CI), 1.22-1.24], although the commonest rescreening interval was 13 months. In 2011, 91.9% of screening tests for women ages 21 to 65 years were negative, 6.6% showed minor abnormalities, and 1.0% high-grade abnormalities. High-grade abnormality rates were relatively constant over time, but minor abnormalities and atypical cells cannot rule out high-grade (ASC-H) were increasing. CONCLUSIONS This population-based evaluation of cervical screening shows high coverage under the age of 40 years, but lower levels in older women. Screening under age 21 years is becoming less common and screening intervals are lengthening, reflecting updates in national screening guidelines. IMPACT Assessment of cervical screening intervals and population outcomes is essential for accurately estimating the impact and effectiveness of changing recommendations and vaccination against human papilloma virus infections.

Abstract
BACKGROUND Although the effectiveness of cervical cancer screening has been firmly established in reproductive-age women, its usefulness in older women is unclear. We sought to evaluate the efficacy of cervical cancer screening in older women. METHODS We conducted a case-control study within two integrated health care systems in the northwestern United States. Cases (n = 69) were women aged 55-79 years who were diagnosed with invasive cervical cancer during 1980-1999. Controls (n = 208) were women with an intact uterus and no diagnosis of cervical cancer, but otherwise similar to cases in terms of age and length of enrollment in the health plan. We reviewed medical records to ascertain screening history during the 7 years prior to reference date. RESULTS Compared to cases, controls were more likely to have received a Pap test. After adjustment for age and current smoking status, screening prior to an estimated 1-year duration of the occult invasive phase of cervical cancer was associated with a substantial reduction in risk [odds ratio (OR) 0.23; 95% CI 0.11-0.44]. Similar results were obtained using different estimates of the duration of the occult invasive phase. Analysis of the relative incidence of invasive cervical cancer in relation to the time following a negative screening test suggested a large reduction during the first year (OR 0.09; 95% CI 0.03-0.24). The incidence remained low for several years thereafter, returning to the incidence among unscreened women after 5-7 years. CONCLUSIONS Cervical cancer screening by means of cytology is highly efficacious in older women. Our findings also suggest that five-yearly screening is approximately as efficacious as more frequent screening.

Abstract
Objective. To determine the frequency of high
risk (HR) HPV and intraepithelial neoplasia following ASCUS pap
cytology screens in menopausal women. Study
Design. Following IRB approval, we performed a
retrospective review of all cases of ASCUS pap tests, HPV results,
and relevant clinical-pathologic data in women age 50 or over from
November 2005 to January 2007 within a tertiary care center.
Statistical analyses were performed in EXCEL.
Results. 344 patients were analyzed for a total
of 367 screening pap tests. 25.29% (87/344) patients were HR
HPV positive, with greater percentages of HR HPV cases occurring
in women age 65–74. Within HR HPV cases, 79.3% (69/87)
underwent colposcopy. 27.5% (19/69) biopsy proven lesions were
discovered, including cervical, vulvar or vaginal (intraepithelial neoplasia). Within the
negative HR HPV group 3.1% (8/257) patients were diagnosed
with dysplasia or carcinoma. Within both HR HPV positive and
negative groups, patients with no prior history of lower genital
tract lesions or cancer were identified.
Conclusion. Reflex HPV testing plays an important
role in ASCUS triage in menopausal women. Pap test screening and
HPV testing should not be limited to women of reproductive age as
they may aid in the diagnosis of intraepithelial neoplasia in
women of older age.

Abstract
Background Lack of knowledge regarding preventive health services for women might impede campaigns to expand these services in the emergency department setting. For 18–55-year-old English-speaking women visiting an urban emergency department, we aimed to: (1) Ascertain their knowledge regarding the applicability, purpose, and recommended intervals of three women's cancer screening and three contraceptive methods; and (2) Determine if patient age, race/ethnicity, medical insurance status, and current or recent usage of these methods are associated with greater or lesser knowledge about them. Methods Emergency department-based survey on recent or current usage and knowledge about Pap smears, breast self-examinations, mammograms, condoms, birth control, and emergency contraception. Analyses included calculation of summary statistics and creation of multivariable logistic regression models. Results Of 1,100 patients eligible for the study, 69.9% agreed to participate. Most of the participants were < age 35, white, single (never married and no partner), Catholic, and had private medical insurance. Participant's recent or current usage of a particular cancer screening or contraceptive method varied by type of method: Pap smear within the past year (69.1%), breast self-exam within the past month (45.5%), mammogram within the past year (65.7% for women age 45–55), condom usage during every episode of sexual intercourse (15.4%), current usage of birth control pills (17.8%), and ever use of emergency contraception (9.3%). The participants correctly answered 87.9% of all survey questions about condoms, 82.5% about birth control pills, 78.5% about breast self-exams, 52.9% about Pap smears, 35.4% about mammograms, and 25.0% about emergency contraception. In multivariable logistic regression models, survey participants who had private medical insurance and those who recently or currently used a given screening or contraceptive method had a greater odds of correctly answering all questions about each cancer screening or contraceptive method. Conclusion Although these female ED patients demonstrated strong knowledge on some women's cancer screening and contraceptive methods, there were several areas of knowledge deficit. Women without private medical insurance and those who have not used a particular cancer screening or contraceptive method demonstrated less knowledge. Reduced knowledge about women's cancer screening and contraceptive methods should be considered during clinical encounters and when instituting or evaluating emergency department-based initiatives that assess the need for these methods.

Abstract
We sought to compare the take-up of cervical screening with Pap smears in a new outreach and pre-existing hospital-based setting (1) to assess the extent to which the two means of provision would overlap; (2) to establish how the utilization rate is influenced by demographic features and geographical distance from the point of provision; and (3) to access whether an outreach service would lead to increased utilization. We used a pre-test-post-test design and used multiple linear regression to assess the effect an outreach service has on utilization after adjusting for participants age, education and martial status. We found that the outreach service independently provided screening to 89% of eligible women and that coverage was inversely associated with distance from the pre-existing hospital provision. After controlling for age, education and martial status, there was a statistically significant increase (53%; 95% CI: 25, 80%) in utilization. There was little overlap between the outreach and hospital-based cervical screening services so that overall accessibility was enhanced, particularly for the elderly, widowed and less well educated. The outreach service also reduced inequalities due to geography.

Abstract
OBJECTIVE The purpose of this study was to determine the effectiveness of interventions designed to improve follow-up after an abnormal Pap smear. METHODS We performed a qualitative meta-analysis of interventions designed to improve follow-up after an abnormal Pap smear and included studies that met the following criteria: randomized or concurrently controlled study design, defined outcomes, and data available for abstraction. Interventions were classified as behavioral, cognitive, sociologic, or combined strategies (e.g., behavioral and cognitive). Abnormal Pap smears were defined as any test result requiring additional follow-up. Effectiveness was measured by the rate of compliance with recommended follow-up. RESULTS Twenty-two interventions in 10 studies met the inclusion criteria. Cognitive interventions utilizing interactive telephone counseling were the most effective, improving compliance by 24 to 31%. Behavioral interventions, such as patient reminders, were also effective, increasing follow-up by up to 18%. Not all of these results achieved statistical significance. The single sociologic intervention we identified used video-taped peer discussions to provide a message about abnormal Pap smears and appropriate follow-up. This intervention was not associated with increased follow-up after an abnormal test. The effectiveness of interventions using multiple types of strategies to improve follow-up was inconsistent. CONCLUSIONS Cognitive strategies led to the greatest improvement in compliance with follow-up of abnormal Pap smear screening tests. Extension of similar interventions to follow-up of abnormal breast and colon cancer screening, development of physician- and system-targeted interventions, and evaluation of the cost-effectiveness of these strategies are important priorities for future research.

Abstract
Factors associated with the level of utilization of screening mammography as a preventive practice were analyzed prior to initiating a population-based breast cancer screening program. A questionnaire was used to collect information about screening mammography utilization during the last 4 years among women invited to enroll in the program. Sociodemographic and health factors, and health services utilization were studied. A screening mammography in the last 4 years had been performed on 59.3% of the 8867 women interviewed. The utilization of mammography was higher among women who were younger, had a higher education level, or had previous visits to a physician (P < 0.001). The variables more strongly associated with use of screening mammography were: visit to a gynecologist and performance of a pap smear. Also associated with the utilization of screening mammography were: personal history of breast pathology, family history of breast cancer, breast self-examination, and recent visit to a general practitioner. Self-perceived health presented an inverse relation with screening mammography use (P < 0.001). The use of screening mammography appears to have increased in recent years, although inequalities persist which the breast cancer screening programs help to modulate. Mammographic frequency only would be deemed appropriate by the European guidelines in fewer than one-half of the cases.

Abstract
Preventive health behavior has been defined as behavior aimed at the prevention or detection of disease in an asymptomatic state. When cervical cancer is discovered and treated in the premalignant stage, the cure rate is 95% or higher. The success of the screening program for cervical cancer depends at least partially on women's acceptance of and compliance with the service. Compliance is related to women's underlying motivation and attitudes to cervical cancer and health and illness in general. The following paper provides an overview of the literature and examines who participates in cervical screening, the participant's feelings about the test and the place of testing, who are unlikely to participate and the reasons for this noncompliance. It is hoped that this overview will indicate possible ways of improving women's acceptance of this screening, whilst identifying negative attitudes and experiences which impede participation.

Abstract
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 and 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.

Abstract
Cytologic screening for cervical cancer has proven to be beneficial in many countries, although the value of this intervention in women older than 50 years remains controversial. The purpose of this study was to investigate the efficiency of detecting cancer in situ by means of a cytologic smear at different ages, with special emphasis on the benefit of screening in women above the age of 50. We analyzed 466,275 smears taken in an open cohort of 118,890 women in Sweden between 1969 and 1988. The number of cancers in situ detected per 1,000 smears, the detection ratio, was used as an outcome measure in univariate analyses and in multivariate regression models. Cancer in situ was detected in 1,076 women in the study cohort. The detection ratio peaked at ages 30 to 34 and decreased heavily during the next 15 years of age. The efficiency of taking smears at ages above 50 was only 20 per cent (OR, 0.19; 95% CI, 0.14-0.26) of that at ages 30 to 34. These results were not changed when adjusting for time period and time interval since the previous smear. In spite of a high incidence of invasive cervical cancer in older women, the benefit of cytologic screening to detect cancer in situ above the age of 50 is uncertain.

Abstract
OBJECTIVES The purpose of the study was to examine the efficacy of a Maryland law requiring Pap testing to be offered during hospital admissions. "In-reach" strategies emphasize cancer screening within existing health care contacts (such as inpatient stays) rather than additional visits solely for screening. METHODS Data from a 1986 telephone survey of Maryland women were used to examine the effect of hospitalization on self-reported Pap testing in a 3-year period. The effect of hospitalization on screening was examined by age and income to assess whether inpatient screening was more prevalent among certain subgroups of women. RESULTS For the group as a whole, the odds of Pap screening did not vary with hospitalization. However, among women aged 45 to 54 years with annual household incomes over $20,000, hospitalized women were more likely than nonhospitalized women to report recent Pap tests. For low-income women aged 75 years and older, hospitalization actually decreased the likelihood of reporting Pap tests. CONCLUSIONS Despite legislation, inpatient cervical cancer screening appears to mirror outpatient patterns, leaving elderly and low-income women unscreened. Methods for increasing inpatient Pap testing for underscreened women are discussed.

Abstract
We examined whether sociodemographic, health, and psychosocial factors predict stage at diagnosis in 444 women aged 55-84 with newly diagnosed, microscopically confirmed breast cancer. Stage was defined as local or advanced (regional or remote). One of the most interesting predictors of disease stage was living arrangement. The odds of being diagnosed with advanced disease were twice as great among women living with a spouse than among women living alone (95% CL = 1.16, 3.35), after adjusting for the effects of age, body mass index, income, comorbid conditions, smoking, and group membership. For those living with someone other than a spouse, the odds of advanced disease were 1.7 times greater than among those living alone (95% CL = 0.96, 3.06). Middle aged and older women who live alone may be more likely to monitor their own health and to use the health care system, and therefore have a greater chance of being diagnosed at an early stage of breast cancer.

Abstract
Older women participate in cervical cancer screening less regularly than do younger women. As a consequence, more lesions are found in more advanced and less curable stages in older women. Elderly black and Hispanic women have had lower rates of participation in cervical cancer screening than white women. There is a marked, inverse relationship between the stage of cervical cancer at diagnosis and the 5-year survival rate. The rate of cervical cancer screening among older women can be increased by offering education about Pap tests and onsite cervical cancer screening in housing for the elderly.

Abstract
Despite the extensiveness of cervical cancer screening programs, certain major issues are still at stake: (a) substantial false negative rates are common, mostly due to impaired test quality, (b) the optimal length of interval between screenings is uncertain, being a function of available resources and the physicians' attitude, (c) the postmenopausal population, in which incidence is highest, is inadequately tapped. Efforts must be made to optimise the process through more stringent control measures, and a more comprehensive cover of the target population.

Abstract
Administrative data have not been used extensively for case-control studies. As an example, data from the Manitoba Health Services Commission were used to assess the effectiveness of Papanicolaou (Pap) testing in screening for cancer of the cervix. Case patients were 415 women with invasive cancer (aged 25 to 64 years) from the Manitoba Cancer Registry and control subjects were women aged 25 to 64 years chosen from a random sample of the Manitoba female population (N = 29,926). For 82% of case patients there was information about Pap testing in a prior 5-year period, as compared to 91% of the controls. Since diagnostic tests could not be distinguished from screening tests, data for the year prior to diagnosis were not used. The odds ratios for Pap testing reducing the risk of cancer of the cervix was 0.82 (95% confidence interval [CI]: 0.53, 1.26) for women aged 25 to 34, 0.55 (95% CI: 0.35, 0.85) for women aged 35 to 44, 0.40 (95% CI: 0.23, 0.69) for women aged 45 to 54, and 0.45 (95% CI: 0.26, 0.78) for women aged 55 to 64. The overall 4-year relative odds adjusted for age and number of physician visits was 0.51 (95% CI: 0.43, 0.61). These results were similar to previously published values obtained from interview studies. Selection and recall bias are minimized and using claims avoids the expense of seeking neighborhood control subjects, carrying out interviews, or performing follow-up searches. As well, true population-based controls can be used.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Utilization of many screening procedures to detect cancer in early stages remains low. In order to design more effective strategies to increase utilization of these tests, we assessed the role and relative importance of different information sources on knowledge and use of cancer screening exams. Where individuals get useful information about disease prevention, and the relationship of information sources to cancer screening knowledge and behavior are reported using data from the 1987 National Health Interview Survey. Results indicate that physicians are perceived as important sources of information on how to prevent illness. However, persons who use print media as their most useful source of information are significantly more likely to have heard of cancer screening procedures than those who rely on the doctor as the source. Those who rely on electronic media tend to be less knowledgeable of all screening procedures examined. A strong and consistent association between doctor as the most useful source of information and actually having received the procedure was found. These results suggest that knowledge may not necessarily be a prerequisite to screening and indicate that reliance on the physician to recommend cancer screening may be critical in utilization of these services.

Abstract
STUDY OBJECTIVE The aim was to establish the public's perception of the relative importance of various environmental risk factors for cancer. DESIGN A postal survey was undertaken using a questionnaire to assess the public's knowledge of cancer morbidity and mortality and the role of lifestyle and genetic risk factors. Sociodemographic data were also collected. SETTING The survey was completed in the state of South Australia. PARTICIPANTS A random sample of 1500 names were selected from the electoral rolls of the state. These rolls contain the names of all Australian citizens over the age of 18 years. A response rate of 73% was achieved. MEASUREMENTS AND MAIN RESULTS The results of the survey showed that the knowledge base of the community was generally high, with few differences across sociodemographic groups. The relative importance of cancer as a contributor to mortality was, however, overestimated and the potential for "cure" underestimated. The role of both diet and cigarette smoking in cancer promotion was widely recognised but there was an overemphasis on the importance of pollution of the food supply compared to imbalance of nutrients. Respondents were more able to assign risk in relation to diet using a food based assessment, compared to a nutrient approach. There was wide acceptability that lifestyle change could have a profound effect on the cancer profile of the community. CONCLUSIONS With the relatively high degree of awareness and acceptance of lifestyle factors as cancer risk determinants, campaigns which involve skill transfer and removal of barriers to change would appear to be the most relevant approach to improvement in community behaviour.

Abstract
As a means of developing effective intervention strategies for promoting Pap smear screening, we analyzed data from a population-based women's health survey (N = 603) in a 36-county area in southeastern Kentucky. The cervical cancer mortality rate for white women in this area is one of the highest in the United States. By using selected sociodemographic, health-care utilization, health knowledge, and health behavior variables in age-specific logistic regression models, we discriminated between women who had had a Pap smear within 3.5 years and those who had not. Several variables predicted Pap screening status regardless of the woman's age. Women of all age groups who had not been recently screened had encounters with the medical-care system. A key variable that affected use of screening services was ever use of birth control pills. The main differences between the three age groups were as follows: the 18-44 age group was less likely to see a private physician and less likely to seek medical care of any type, except for care related to pregnancy; only the 45-59 age group believed that cost of medical care was a problem; and only for the 60 or older age group were socioeconomic variables associated with not having recently had a Pap test.

Abstract
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.

Abstract
The clinical, patient-oriented focus of medicine and psychology is contrasted with the epidemiologic (public health) approach in assessing the role of life-style factors and health promotion in cancer research. The unifying host-agent-environment epidemiologic paradigm is applied to contemporary cancer prevention issues, principally smoking cessation and dietary modification, to demonstrate differences in inferences, prevention strategies, and research opportunities. An integration of population-based approaches with the dynamics of patient behavior and risks for cancer is especially salient when considering the role of psychosocial stress and personal and social resources. The social epidemiologic perspective, the study of the psychosocial determinants of physical health status, offers one approach for resolving the outlined differences in perspectives and is particularly relevant for understanding the etiology of life-style behaviors and how they might be altered.

Abstract
Case-control studies have been used in recent years to evaluate the efficacy of cancer screening. However, relatively little work has been done to examine the methodology itself for this purpose. In this paper, it is demonstrated that because of self-selection bias the case-control study can yield a biased estimate of screening efficacy. Further, it is shown how this bias can be assessed using data from a randomized trial. Using data from the HIP breast cancer screening study, the magnitude of the self-selection bias is estimated and is seen to be substantial.

Abstract
Relative and population attributable risks for invasive cervical cancer in different age strata relative to screening practices have been estimated using data from a case-control study conducted since 1981 in the greater Milan area, northern Italy. A total of 548 women under 75 years of age with a histologically confirmed diagnosis of invasive cervical cancer were compared with 515 controls admitted to hospital for a spectrum of nongynecological, hormonal or neoplastic, acute conditions. The percentage of never-screened women increased with age: no Pap smear was reported in 34% of controls aged 44 years or younger and 63% of older women (greater than or equal to 65 years). A similar trend emerged in recency of Pap smear, with 14% of older controls and 52% of the younger group reporting a cervical smear within 3 years before the interview. The number of Pap smears was strongly and inversely related to cervical cancer risk at all ages. Compared with no Pap smear, three or more cervical smears decreased the risk of invasive cervical cancer by about 90%. Compared with women screened the last time 6 years before the interview or never, relative risks were about 60% lower in women reporting their last Pap within 2 years in all age groups. A slightly larger proportion of older cases were attributable to the absence or delay in the screening: population attributable risk estimates were 78% in women up to 55 years of age, and 86% in those 65 years or older. Thus, deficiencies in screening were greater at ages at which the incidence of disease was higher.

Abstract
This study investigated the relationships between health care utilization, knowledge, attitudes, sociodemographic characteristics, and adequacy of cervical cancer screening among a random sample of women from inner-city neighborhoods with high rates of cervical cancer mortality. Of 416 women interviewed, 30.3% reported hysterectomies; women with intact uteri (N = 290) are the subjects of this analysis. Over two-fifths (44.1%) reported not receiving adequate Pap testing during the previous 4 years. Compared with adequately screened women, they were more likely to be 45 years or older, have no medical insurance, report never having been to an obstetrician-gynecologist, recall never having been told by a medical provider how often to get a Pap test, rely on providers for adequate screening, report not seeking care as often as they think they should, have less knowledge of risk factors for cervical cancer, and believe that women should get Pap tests less than yearly. Separate models for younger and older women showed that these factors vary by age, demonstrating the need for interventions to be sensitive to age subgroups. These findings suggest that cancer control activities should place more emphasis on motivating women as well as influencing the health care delivery system to maximize reductions in cervical cancer.

Abstract
Cervical cancer is an important cause of cancer mortality in black women. Pap tests may prevent such deaths, but poor, rural black women are relatively less likely than others to be screened. In order to understand why that is so, the authors surveyed 149 women in three rural North Carolina counties. Thirty-three percent of the women interviewed had not had a Pap test in the preceding three years. Variables independently associated with not having a recent Pap test included: having no identifiable source of medical care; having more than one source of gynecologic care; having an internist provide gynecologic care; and perceiving psychological barriers to Pap tests and pelvic examinations. Income, educational level, and health insurance status were not associated with having a recent Pap test. Although access to care remains a problem for some, better use should be made of the medical care encounters available.

Abstract
Despite recommendations by the American Cancer Society and other organizations for use of screening mammography, data on reported utilization of this procedure by American women show that these guidelines are not being met. We reviewed published studies that reported participation rates or that examined factors associated with participation in selected breast screening programs. In general, women at high risk due to age and family or personal history of breast disease were not more likely to participate in breast screening programs than women without those risk factors. The one group of variables that was fairly consistently associated with participation was the practice of other preventive health behaviors. Women who expressed more concern about their health and who were more knowledgeable about breast cancer screening and its benefits also were more likely to complete mammography. Approaches to increasing participation are discussed in the context of the literature on this subject.
