Development of a cervical cancer control intervention program for Cambodian American women.

Southeast Asian immigrants have lower levels of Pap testing than any other racial/ethnic group in the US, and are particularly unfamiliar with western culture and biomedical concepts of prevention. We completed an ethnographic study (N = 42) focusing on cervical cancer screening among Cambodian American women. We also conducted a community-based survey (N = 413) to examine the generalizability of our qualitative results. This report summarizes the results, and describes how we used our findings to influence the content of a multifaceted intervention program targeting Cambodian immigrants. The following constructs were found to be barriers to cervical cancer control: a traditional orientation to the prevention, causation, and treatment of disease; lack of familiarity with western early detection concepts; low levels of knowledge about cervical cancer; concerns about the Pap testing procedure; and health care access issues. In general, the quantitative results confirmed our ethnographic findings. The intervention program, which is delivered by bicultural outreach workers, includes home visits, presentations at small group meetings, barrier-specific counseling, use of a Khmer-language video, and tailored logistic assistance (e.g., transportation and medical interpretation). Both the video and presentation provide cultural context while simultaneously addressing multiple barriers to screening (e.g., women's fear of surgery and preference for female providers). Outreach workers are trained to counsel women about 10 potential barriers including avoidance of biomedicine, perceptions that gynecologic exams are embarrassing, and lack of English proficiency. Our results reinforce the importance of considering health problems within the context of a population's traditional belief systems and daily routines.

Bridging cultures through the development of a cervical cancer screening video for Cambodian women in the United States.

BACKGROUND: Southeast Asian women have higher invasive cervical cancer rates than any other U.S. racial/ethnic population subgroup, and their levels of Pap testing do not even approach the year 2000 goals. Video is a particularly useful medium for cancer education in Cambodian refugee communities because of low literacy levels and high rates of VCR ownership. METHODS: The authors produced a motivational Pap-testing video for Cambodian American women. The 18-minute Khmer-language video is entitled "The Preservation of Traditions." Content, with respect to cervical cancer screening barriers and facilitators, was guided by intensive qualitative data collection. Barriers addressed were: beliefs that traditional postpartum practices protect against cervical disease, Cambodians do not get cervical cancer, and screening is unnecessary; fear of cancer as well as surgery; lack of understanding about preventive concepts and familiarity with the Pap test; concerns about embarrassment and pain; and problems with transportation and child care. Facilitators included the availability of female physicians and interpreters. A community coalition of Cambodian women and two community advisors participated in all aspects of the video development and production. Video techniques frequently used in American productions were adapted to the target audience. For example, cultural context was provided, use of biomedical terminology minimized, role modeling emphasized, and testimonial accounts avoided. CONCLUSION: The processes used to translate empirical evidence into meaningful educational messages, and to adapt American behavioral change techniques to Cambodian cultural norms, are generalizable to other less acculturated immigrant groups and cancer education topics.

A clinic-based mammography intervention targeting inner-city women.

OBJECTIVE: The objective was to evaluate the effect of a clinic-based intervention program on mammography use by inner-city women. DESIGN: A randomized controlled trial employing firm system methodology was conducted. SETTING: The study setting was a general internal medicine clinic in the university-affiliated county hospital serving metropolitan Seattle. PARTICIPANTS: Women aged 50 to 74 years with at least one routine clinic appointment (when they were due for mammography) during the study period were enrolled in the trial (n = 314). INTERVENTIONS: The intervention program emphasized nursing involvement and included physician education, provider prompts, use of audiovisual and printed patient education materials, transportation assistance in the form of bus passes, preappointment telephone or postcard reminders, and rescheduling assistance. Control firm women received usual care. MEASUREMENTS AND MAIN RESULTS: Mammography completion within 8 weeks of clinic visits was significantly higher among intervention (49%) than control (22%) firm women (p < .001). These effects persisted after adjustment for potential confounding by age, race, medical insurance coverage, and previous mammography experience at the hospital (odds ratio 3.5; 95% confidence interval 1.9, 6.5). The intervention effect was modified by type of insurance coverage as well as prior mammography history. Process evaluation indicated that bus passes and rescheduling efforts did not contribute to the observed increases in screening participation. CONCLUSIONS: A clinic-based program incorporating physician education, provider prompts, patient education materials, and appointment reminders and emphasizing nursing involvement can facilitate adherence to breast cancer screening guidelines among inner-city women.

Mammography use among women attending an inner-city clinic.

BACKGROUND: Low-income, minority, and inner city women have breast cancer screening rates that are below those of the general population. METHODS: The authors surveyed women who received primary care at Seattle's county hospital about their mammography behaviors in early 1995. Data were analyzed within the context of the PRECEDE framework. RESULTS: Only half (48%) of the women were obtaining regular screening. Breast cancer and mammography beliefs differed by racial group. The following factors differentiated between inner-city women who were and were not regular users: mammography beliefs concerning early detection of disease, pressure from the machine causing breast cancer, and cost (these were less important among white women than members of other racial groups); previous physician discussions, concerns about appointment scheduling, and transportation problems; and social support from physicians, family, and friends. CONCLUSION: Interventions to encourage regular screening among inner-city women should address predisposing, enabling, and reinforcing factors.

Anthropometric and hormone effects of an eight-week exercise-diet intervention in breast cancer patients: results of a pilot study.

To assess the feasibility of an exercise-diet intervention in sedentary, overweight breast cancer patients, we conducted a pilot 8-week intervention. Recruitment letters and interest surveys were sent to 99 stage 1 or 2 breast cancer patients, ages 25-75 years, who were identified through two Seattle breast surgery practices and the University of Washington Breast Clinic. Ten patients were eligible and interested and were enrolled in the intervention, which consisted of thrice-weekly monitored aerobic exercise sessions and a low-fat (20% of calories from fat) diet. Nine patients completed the program; all adhered well to the intervention and data collection protocol. The patients, ages 40-74 years, lost, on average, 2.6 pounds of body weight, 3.4 cm in waist circumference, 4.6 cm in hip circumference, 2.3% body fat, 3.3 systolic blood pressure points, 0.67 diastolic blood pressure points, and 4.0 pulse beats/min, and they gained an average of 2.3% lean mass. Slight, nonsignificant decreases were observed in serum concentration of total and free estradiol, estrone sulfate, total testosterone, androstenedione, and dehydroepiandrosterone. These pilot data indicate that breast cancer patients are highly motivated to join and adhere to an intense exercise-diet intervention and can experience significant measurable changes in anthropometric and fat mass measures.

Understanding mammography intention and utilization among women in an inner city public hospital clinic.

BACKGROUND: Most research on mammography utilization has been conducted among middle-class women. There is a need for research to identify factors affecting mammography utilization among low-income women to develop effective interventions for this underserved subgroup. METHODS: An expanded theory of reasoned action guided this research among low-income inner-city women who use a public hospital. Qualitative interviews were conducted to develop a questionnaire with items relevant to this population. The questionnaire included 5 affect measures, 13 behavioral beliefs, 5 sources of influence, and 6 facilitator/constraint measures. The survey was mailed to 584 women ages 50 to 69 identified through the hospital database. RESULTS: After those ineligible and undeliverable were excluded, responses rates were obtained from 361 women (84% adjusted response rate). Sixty-six percent had a mammogram within the previous year and 58% were very sure that they would get a mammogram in the next year. Affect, attitude, subjective norm, and facilitator scores were computed. All four constructs had significant correlations (r = 0.38 to 0.41) with intention to get a mammogram in the next year and all had significant multiple regression weights (R = 0.54). All but three items making up the model components were significantly correlated with screening intention. CONCLUSIONS: The data from applying a behavioral model indicate that intervention efforts to increase mammography utilization among low-income women should target all four model components. A clinic-based intervention could use multiple methods to deliver messages developed to target each of the model component items found to be associated with mammography intention.

Computerized tomography assessment of women with weight changes associated with adjuvant treatment for breast cancer.

It is common for women undergoing treatment for breast cancer to gain weight, although the characteristics of the weight change have not been described. We investigated the changes in abdominal fat accumulation that accompanied the change in weight associated with treatment for breast cancer in longitudinal and cross-sectional clinical studies in 34 women aged 39-73 y with early-stage primary breast cancer. Computerized tomography scans of abdominal subcutaneous and visceral adipose depots, bioelectrical impedance measurements of body fat mass, and measurements of body weight and girth were obtained early in the course of treatment and 6 mo later (longitudinal study; n = 8) or within 12 mo of treatment (cross-sectional study; n = 26). The longitudinal study found that, irrespective of the direction of weight change, seven of eight women gained body fat and lost lean body mass. In the five women who gained weight (median: 3.2 kg) two lost and three gained subcutaneous adipose fat (median: 19%) whereas all gained visceral fat (median: 23%). In the cross-sectional study 19 women gained weight and 7 lost weight or had stable weight since diagnosis. Change in weight was correlated with abdominal subcutaneous adipose fat (r = 0.39; P = 0.06) and hip circumference (r = 0.43; P = 0.03) but not abdominal visceral fat, the ratio of subcutaneous to visceral fat, or the ratio of waist to hip size. In the longitudinal sample, weight gain resulted in a variable response in subcutaneous adipose volumes but a consistent increase in visceral adipose depot. Although these results are preliminary, it appeared that regardless of weight gain or loss women were likely to lose lean body mass and gain fat mass during treatment for breast cancer.

Attitudes and beliefs toward mammography among women using an urban public hospital.

Although overall use of mammography is steadily increasing, low-income and minority women consistently have relatively lower screening rates than white, middle-class women. To assess the mammography-seeking behavior of low-income women using an urban public hospital, this study sought to understand why women in this population decide whether or not to obtain a screening mammogram. Two qualitative techniques, elicitation interviews and focus groups, were used to develop an understanding of attitudes, concerns, and barriers of this group relative to mammography. Fear, embarrassment, susceptibility to breast cancer, inconvenience, cost, concerns about efficacy of mammography, fear of acquiring cancer, and scheduling difficulties were identified as important concerns. "People in the news" were the most influential social referents for mammography decision making, followed by physicians, family members, and friends. The insights gained from these women will assist in developing interventions that encourage mammography-seeking behavior by low-income women.

Randomized trial of breast self-examination in Shanghai: methodology and preliminary results.

BACKGROUND: The efficacy of breast self-examination in helping to reduce mortality from breast cancer has not been rigorously demonstrated. PURPOSE: To assess efficacy, a large, randomized trial was initiated in Shanghai, China. METHODS: From October 1989 to October 1991, 267040 current and retired female employees associated with 520 factories in the Shanghai Textile Industry Bureau were randomly assigned on the basis of factory to either a self-examination instruction group (133375 women) or a control group (133665 women). The women were born within the period from 1925 through 1958. Women in the instruction group were given intensive training in breast self-examination, including the use of silicone breast models and personalized instruction, plus two subsequent reinforcement sessions and multiple reminders to practice the technique. Women in the control group were asked to attend training sessions on the prevention of low back pain. All women have been followed for the development of breast diseases and for death from breast cancer. RESULTS: A high level of participation during the first 4-5 years of the trial was documented among women in the instruction group. Randomly sampled women in this group demonstrated greater proficiency in detecting lumps in breast models than did randomly sampled women in the control group. Approximately equal numbers of breast cancers were detected in the two groups (331 in the instruction group and 322 in the control group) through 1994, which is the last year for which case-finding efforts have been completed. The breast cancers detected in the instruction group were not diagnosed at an appreciably earlier stage or smaller size than those in the control group. More benign breast lesions were detected in the instruction group than in the control group (1457 versus 623, respectively), suggesting a higher index of suspicion for women who received training. Cumulative breast cancer mortality rates through 5 years from entry into the study were nearly equivalent for the two groups. CONCLUSIONS: Breast self-examination has not led to a reduction in mortality from breast cancer in this study cohort in the first several years since the trial began. A shift toward the diagnosis of disease at a less advanced stage in women given instruction has also not been demonstrated. Longer follow-up of participants in this trial is required before final assessment can be made of the efficacy of breast self-examination. IMPLICATIONS: At this time, there is insufficient evidence to recommend for or against the teaching of breast self-examination.

Community organization to promote breast cancer screening ordering by primary care physicians.

Community organization has been viewed as a promising approach to changing preventive behaviors. We evaluated the impact of community organization strategies to promote breast cancer screening ordering by primary care physicians in Washington State. Physicians practicing in two intervention and two control communities were surveyed by mail pre-intervention (1989) and post-intervention (1993). Intervention activities targeting the health care sector included the formation of local physician planning groups, a series of informational mailings, medical office staff training sessions, and reminder system support. There were no significant post-intervention differences in the self-reported mammography ordering of physicians practicing in the intervention and control areas. Over the four-year study period, the proportions of physicians who ordered regular mammography increased by 36%. By 1993, over 80% of the respondents routinely used mammographic screening. Concerns about the high price of mammograms and inadequate insurance coverage were significantly reduced over time in both community pairs. Also, use of patient reminder systems increased significantly between 1989 and 1993. Secular trends resulting from diffusion of strategies to promote mammography were responsible for increases in physician ordering of the procedure. Year 2000 goals for breast cancer screening use by physicians may already have been met in some communities.

Community organization to promote breast cancer screening among women ages 50-75.

BACKGROUND: To reduce breast cancer mortality, ways to promote the use of mammography screening among women age 50 and above are needed. Community organization may be a useful approach. METHODS: The Washington State Community Breast Cancer Screening Project involved implementation of promotional activities initiated by physician and lay community boards in two communities. Two comparable communities served as controls for evaluation purposes. Random-digit-dial telephone interviews were used to assess recent use of mammography at baseline and follow-up in independent samples of women ages 50 to 75 from the four communities. The extent of exposure to intervention activities and the relationship between exposure to intervention activities and mammography use were estimated from data collected at follow-up. RESULTS: Exposure to patient reminders from physicians, wallet reminder cards, and newspaper advertisements were consistently related to mammography use. Physician office staff encouragement and a display board were significantly related to mammography use only in Intervention Communities A and B, respectively. Neither exposure to promotional activities nor the change in prevalence of mammography use was significantly higher in the intervention communities than in the comparison communities at follow-up. CONCLUSIONS: Although several activities were useful in promoting mammography use, organization of the community did not enhance efforts undertaken spontaneously by comparable communities.

Medical community involvement in a breast cancer screening promotional project.

The analysis, mobilization, and involvement of medical communities in two counties targeted for intervention by the Washington State Community Breast Cancer Screening Project is described. Principles of community organization were applied to the health care sectors in the counties, and the PRECEDE-PROCEED model was used as a conceptual framework for considering individual physician behavior. Quantitative and qualitative medical community assessment methods included a demographic study, a survey of primary care physicians, personal interviews with physicians, and medical office staff focus groups. In both intervention areas, physician planning groups selected, developed, and helped implement intervention activities targeting the health care sectors. These activities included informational mailings to physicians, training of medical office staff members and clinical mammographers, and support for a reminder system. The experience demonstrated that physicians practicing in medium-sized cities are willing to be active in community disease prevention programs.

A breast cancer screening educational intervention targeting medical office staff.

There is persistent evidence that breast cancer screening techniques remain under-utilized. While physicians cite lack of time as a barrier to the provision of preventive services, nurses and other medical office staff are in an ideal position to educate women and motivate adherence to screening recommendations. This paper describes the design, implementation and process evaluation of a breast cancer screening educational program targeting primary care medical office staff. This intervention was conducted in two Washington State counties as part of a larger community organization study. The PRECEDE model, educational outreach principles and focus groups were used to guide the program development. Consistent with 'academic detailing' concepts, the sessions were delivered at health care facilities. The program included a review of breast cancer-related data and screening methods, an overview of the nurse's role as a 'change agent' and breast self-examination instructor, and a discussion of women's barriers to mammography. Community-level penetration was relatively high, with sessions being completed by approximately 50% of the eligible staff. Overall, participants were positive about the value of the program. Medical office-based educational sessions have the potential of reaching a large proportion of primary health care workers and increasing disease prevention in communities.

Comparative analysis of modeling techniques for coliform organisms in streams.

The use of models for predicting changes in water quality parameters is currently considered an integral part of river basin management. The application of modeling techniques to coliform organisms is in its infancy due to the complexities involved and the lack of definitive information on coliform populations in natural environments. The purpose of this study was to make a comparative analysis of the available models for coliform organisms in order to improve on the state of the art of this subject. The available coliform models may be classified into deterministic or statistical types. In this study, six different models, three of each type, were selected for analysis and were applied to coliform data available on the Leaf River. Results of comparing the models indicated that a deterministic model was best suited for total coliform and a statistical model was best suited for fecal coliform. Ultimate selection of a model for coliform organisms is dependent not only on the accuracy of the model but on ease of implementation. Current technology would probably dictate the use of a deterministic model because of the lack of a complete data base on which to base statistical models.
