The Texas Breast Screening Project: Part II. Demographics, risk profiles, and health practices of participants

Tailored messages, external barriers, and women's utilization of professional breast cancer screening over time

BACKGROUND

The efficacy of tailored messages on women's utilization of professional breast screening over time has not been examined often or in combination with external barriers (e.g., costs and access). The objectives of this study were to test the effects of alternative messages on mammography and clinical breast examination (CBE) utilization over time and to examine the combined effects of such messages and external barriers.

METHODS

In a randomized, controlled trial, three message conditions were compared: no message (control group), recommendations about screening, or recommendations plus tailored discussion (on beliefs, feelings, costs, and access). Messages were delivered by advanced practice nurses over the telephone. Participants were women ages 51-80 years who had not had mammography in the prior 13 months. Outcome measures were women's mammography and CBE utilization 3-6 months postintervention (short-term follow-up) and 13-16 months after short-term follow-up (long-term follow-up).

RESULTS

Both messages promoted mammography and CBE utilization at short-term follow-up. Utilization increased over time in all groups. Mammography utilization was greater for the tailored-message group compared with the recommendations-only group at long-term follow-up. Messages and external barriers had combined effects (Ps < 0.01). Among participants with high external barriers, participants in the message conditions-especially the tailored message-had the highest screening rates; among participants with low barriers, screening rates were similar across conditions.

CONCLUSIONS

Clinicians can tailor discussions on beliefs, feelings, cost, and access about screening to promote professional breast screening over time, especially with women who have not had mammograms as recommended and who have external barriers to screening.

Mammography and Pap test screening among low-income foreign-born Hispanic women in USA

Little is known about the factors influencing screening among low-income Hispanic women particularly among recent immigrants. A sample of 148 low-income, low-literate, foreign-born Hispanic women residing in the Washington DC metropolitan area participated in the study. The mean age of the sample was 46.2 (SD=11.5), 84% reported annual household incomes ($15,000. All women were Spanish speakers and had low acculturation levels. Ninety six percent had reported having a Pap smear, but 24% were not in compliance with recommended screening (Pap test within the last 3 years). Among women 40 and older, 62% had received a mammogram, but only 33% were compliant with age appropriate recommended mammography screening guidelines. Women in this study had more misconceptions about cancer than Hispanics in other studies. Multivariate logistic models for correlates of Pap test and mammography screening behavior indicate that factors such as fear of the screening test, embarrassment, and lack of knowledge influenced screening behavior. In conclusion, women in this study had lower rates of mammography screening than non-Hispanic women and lower rates of compliance with recommended Mammography and Pap test screening guidelines.

Improved screening for breast cancer associated with a telephone-based risk assessment

BACKGROUND

Our objective was to develop and field-test a telephone-based breast cancer risk assessment and to assess its efficacy in improving screening behavior. The study was performed at a financial institution and a manufacturing corporation with main offices in Boston, Massachusetts, and branch offices in various regions of the United States.

METHODS

A longitudinal study consisting of an initial health risk assessment administered by telephone, with a subsequent follow-up study initiated 8 months later, was performed. Study design was influenced by some of the suggestions made by the benefits departments of the corporate sponsors. A voice-response, telephone system collected risk information from callers and gave real-time risk assessment. These callers could receive a risk assessment over the phone and remain completely anonymous or furnish name and address to receive a more detailed written report. Main outcome measures included the response rate and demographics of the respondents, risk profiles of the callers, and breast cancer screening statuses.

RESULTS

There were 343 participants of whom 189 relinquished anonymity to receive more detailed information by mail and were available for a follow-up study. Sixty-three women (18%) reported a family history of breast cancer, with 34 women (10%) responding that one first-degree blood relative had been diagnosed before the age of 50. A strong positive correlation between the level of familial risk and the decision to remain anonymous existed (P < 0.0001). There was an increase in compliance with breast self-examination from 34% (40/119) at time of use of the system to 62% (74/119) at follow-up, P < 0.0001. Clinical breast exams showed similar improvements, from 82 (98/119) to 92% (110/119), P < 0.0137. Paired and unpaired data of women 40 years of age and older indicate an improvement in mammography compliance from time of system use to follow-up, 76 (22/29) to 93% (27/29), P < 0.0572, and 79 (33/42) to 93% (27/29), P < 0.0129, respectively.

CONCLUSIONS

A population of women with a risk profile higher than that of the U.S. population called the survey. System use is associated with an improvement in breast cancer screening habits. Self-reported, increased genetic risk for breast cancer was strongly correlated with a decision to remain anonymous.

Breast and cervical cancer screening among women with physical disabilities

OBJECTIVE

This article reports findings from the National Study of Women with Physical Disabilities about rates of screening for breast and cervical cancer and factors associated with regular screening in a large sample of women with a variety of physical disabilities and a comparison group of women without disabilities.

DESIGN

Case-comparison study using written survey. Data were analyzed using measures of central tendency, chi 2 analysis, logistic regression, and risk using odds ratios.

SETTING

General community.

PARTICIPANTS

A total of 843 women, 450 with disabilities and 393 of their able-bodied friends, aged 18 to 65, who completed the written questionnaire. The most common primary disability type was spinal cord injury (26%), followed by polio (18%), neuromuscular disorders (12%), cerebral palsy (10%), multiple sclerosis (10%), and joint and connective tissue disorders (8%). Twenty-two percent had severe functional limitations, 52% had moderate disabilities, and 26% had mild disabilities.

MAIN OUTCOME MEASURES

Outcomes were measured in terms of frequency of pelvic exams and mammograms.

RESULTS

Women with disabilities tend to be less likely than women without disabilities to receive pelvic exams on a regular basis, and women with more severe functional limitations are significantly less likely to do so. No significant difference was found between women with and without disabilities, regardless of severity of functional limitation, in receiving mammograms within the past 2 years. Perceived control emerged as a significant enhancement factor for mammograms and marginally for pelvic exams. Severity of disability was a significant risk factor for noncompliance with recommended pelvic exams, but not mammograms. Race was a significant risk factor for not receiving pelvic exams, but not mammograms. Household income and age did not reach significance as risk factors in either analysis.

CONCLUSIONS

Women with physical disabilities are at a higher risk for delayed diagnosis of breast and cervical cancer, primarily for reasons of environmental, attitudinal, and information barriers. Future research should focus on the subpopulations that were not surveyed adequately in this study, women with disabilities who have low levels of education or income, or who are of minority status.

Acceptability of mobile mammography among community-dwelling older women

OBJECTIVE

To test the acceptability of mobile mammography among community-dwelling older women and to identify factors predictive of mobile mammography acceptance.

DESIGN

Case series.

SETTING

Twelve community meal sites sponsored by the City of Los Angeles Area on Aging.

PARTICIPANTS

Two hundred fifty-five volunteers aged 60 to 84 years who attended community meal sites.

INTERVENTION

On-site mammography offered to women who had not had a mammogram within the last year.

MEASUREMENTS

Mammography acceptance rates, reasons for accepting or declining the mammogram, and breast cancer knowledge, beliefs, and intentions.

MAIN RESULTS

One hundred seven of the 255 (42%) women were ineligible because they had received mammograms within the last year. Of the 148 women eligible, 57% accepted the mammograms and 43% declined; moreover, 20 of the 42 (48%) women who had not had a mammogram within the last 5 years or who never had a mammogram also accepted on-site mammography in the mobile van. Variables identified as predictive of mammogram acceptance included Asian American status, not being an HMO member, being married, a reported willingness to accept a screening mammogram if recommended by a physician, and previous mammogram screening history.

CONCLUSION

Mobile mammography is acceptable to many older community-dwelling women. Although mobile mammography does not eliminate all barriers that inhibit a woman from receiving a mammogram, it may substantially increase screening for some groups.

A national survey of attitudes regarding participation in prostate carcinoma testing

BACKGROUND

The prevalence of prostate carcinoma testing is rapidly changing. Little is known about the frequency of testing in the non-Medicare population in the United States. The current study was conducted for a better understanding of who is being tested and some of the reasons why.

METHODS

A randomized national telephone survey was administered to 800 men by the George H. Gallup International Institute. Questions in the survey were evaluated for their association with participation in prostate carcinoma testing reported by the men interviewed.

RESULTS

Participation in prostate carcinoma testing approximated the frequency of colon carcinoma testing Eighty-six percent of the men surveyed believed that prostate carcinoma is a serious malignancy, and 78% believed that it could be cured often if detected early. Multivariate logistic regression models identified six factors that increased the likelihood of men in the survey being tested: white race, willingness to be tested, previous conversation with a physician or health professional, having had serum cholesterol tested, having been tested for colon carcinoma, and belonging to successively advanced age groups.

CONCLUSIONS

Prostate carcinoma testing is commonly performed in men older than 40 years. Physician counsel and patient prevention consciousness appear to be the major influences when a patient decides to be tested. If early detection is considered beneficial, special efforts would be needed to reach the nonwhite population.

Financial incentive and the use of mammography among Hispanic migrants to the United States

Researchers in migrant health clinics in Washington state found cost to be the single most commonly reported reason given by foreign-born Hispanic women for never having had a mammogram. The true significance of this finding beyond self-report was unknown. A randomized intervention trial designed to test the effect of fully subsidized mammograms on utilization was conducted within this population. Women in the intervention group received standard clinic instruction plus a voucher for a free mammogram. Controls received standard clinic instruction alone. Eighty-seven percent of women receiving vouchers obtained a mammogram within 30 days, compared with 17.5% of controls. Logistic regression analysis revealed that women receiving vouchers were 47 times more likely to obtain a mammogram than controls. This confirms women's self-report that cost is a major barrier to accessing screening mammograms in this low-income migrant population, and that women are more likely to utilize this service when financial barriers are removed.

Patient compliance in mobile screening mammography

RATIONALE AND OBJECTIVES

We assessed the follow-up behavior of women who had abnormal results of screening mammograms taken on a mobile van.

METHODS

A retrospective cohort study was conducted between 1988 and 1991 of all women served by a mobile mammography van in rural North Carolina. Compliance with radiologist recommendations for follow-up was assessed through review of patient records and mail surveys of patients with incomplete records.

RESULTS

Compliance was 44% for negative or benign mammograms, 57% for indeterminate mammograms, and 62% for probably malignant or malignant mammograms. Women who had a previous mammogram or had a malignant finding were more likely to comply with follow-up recommendations (p < .0001) than women with normal or benign results and no history of mammography. Compliers and noncompliers did not differ with respect to family history of breast cancer or personal history of breast discomfort.

CONCLUSION

Compliance with recommendations in this setting was lower than expected. This may be because rural women using mobile van mammography have limited access to the resources needed for appropriate follow-up. Further research is needed to examine explanations for poor compliance in this setting.
