Should "acculturation" be a variable in health research? A critical review of research on US Hispanics

Acculturation has become a popular variable in research on health disparities among certain ethnic minorities, in the absence of serious reflection about its central concepts and assumptions. Key constructs such as what constitutes a culture, which traits pertain to the ethnic versus "mainstream" culture, and what cultural adaptation entails have not been carefully defined. Using examples from a systematic review of recent articles, this paper critically reviews the development and application of the concept of acculturation in US health research on Hispanics. Multiple misconceptions and errors in the central assumptions underlying the concept of acculturation are examined, and it is concluded that acculturation as a variable in health research may be based more on ethnic stereotyping than on objective representations of cultural difference.

Genetic research and health disparities

Alleviating health disparities in the United States is a goal with broad support. Medical research undertaken to achieve this goal typically adopts the well-established perspective that racial discrimination and poverty are the major contributors to unequal health status. However, the suggestion is increasingly made that genetic research also has a significant role to play in alleviating this problem, which likely overstates the importance of genetics as a factor in health disparities. Overemphasis on genetics as a major explanatory factor in health disparities could lead researchers to miss factors that contribute to disparities more substantially and may also reinforce racial stereotyping, which may contribute to disparities in the first place. Arguments that promote genetics research as a way to help alleviate health disparities are augmented by several factors, including research funding initiatives and the distinct demographic patterns of health disparities in the United States.

Exploring loss to follow-up: abnormal Pap screening in Hispanic patients

PURPOSE

The loss of patients to follow-up for abnormal findings from Pap screenings is an important public health concern, particularly among poor and minority women. This study explores factors affecting incomplete follow-up among a group of Hispanic women with low incomes.

DESCRIPTION OF STUDY

A qualitative descriptive study was conducted of 11 Hispanic patients with incomplete Pap smear follow-up at a public clinic in a major city in south Texas. Patients were interviewed using a semistructured, open-ended schedule of questions, and their medical records were abstracted. The clinic's five staff members also were interviewed. Comparative chronologies were constructed for each case, contrasting patient and staff accounts of the same set of events. All data were coded by at least two investigators.

RESULTS

All study patients had mildly abnormal Pap smear results and had not met the follow-up criteria, but all understood and were committed to Pap screening. Although viewed by staff as noncompliant, none of the patients viewed her behavior this way. This staff-patient discrepancy was attributable to poor communication, mixed messages, clinic errors, and, perhaps most importantly, to a conflict between program policies and the specific circumstances of individual cases. Two case examples are presented to illustrate key points.

CLINICAL IMPLICATIONS

Strategies that may help to reduce loss to follow-up among similar patients include the following: allowing clinic staff more flexibility in follow-up procedures for women who have consistently normal follow-up tests, including Spanish translations of written messages; enlisting patients' agreement in setting appointments; and updating patient records to reflect follow-up care that had been received in other clinics.

Childbirth care-seeking behavior in Chiapas

This study was designed to better understand how women in a developing region choose between the multiple options available to them for birthing. We conducted focused, open-ended ethnographic interviews with 38 nonindigenous, economically marginal women in Chiapas, Mexico. We found that although medical services for birthing were readily available to them, these women most often chose traditional birth attendants (TBAs) for assistance with their births. They expressed a clear preference for TBAs in the case of a normal birth, but viewed medical services as useful for diagnosing and managing problem deliveries and for tubal ligations. They favored TBAs because they valued being able to choose birthing locations and birthing positions and to have relatives present during the birth, all features they must give up for medically attended births in this region.

Development of a life events/icon calendar questionnaire to ascertain occupational histories and other characteristics of migrant farmworkers

BACKGROUND

Specialized methods are necessary to collect data from migrant farmworkers for epidemiologic research.

METHODS

We developed a questionnaire that collected lifetime occupational histories and other lifestyle risk factors via a life events/icon calendar, and administered the questionnaire to a convenience sample of 162 migrant farmworkers in nine areas of the U.S.

RESULTS

The average duration of the interviews was about 1 h 30 min, with an average of 45 min for the work history section. The occupational histories covered a median of 27.6 years per person for men and 20.8 years per person for women. The median number of years spent in farm jobs was 11.3 for men and 5.8 for women. The median number of farm jobs (crop/task combination) per person was 59 among men and 27 among women. Many farmworkers performed the same crop/task combinations at multiple times throughout their lives, yielding a median of 13 unique farm jobs and 8 unique crops among men and 7 jobs and 5 crops among women.

CONCLUSIONS

The project demonstrated that it is feasible to collect detailed work histories and other risk factor data from farmworkers, documented the complexity of work histories encountered among farmworkers, and yielded recommendations for refining a questionnaire that will facilitate future epidemiologic research on farmworkers.

An analytical framework for contrasting patient and provider views of the process of chronic disease management

Medical anthropologists involved in clinical research are often asked to help explain patients' "noncompliance" with treatment recommendations. The clinical literature on "noncompliance" tends to problematize only the patient's perspective, treating the provider's perspective as an uncontroversial point of departure. Explicating the articulation between provider and patient assumptions, expectations, and perceptions in managing chronic illness is an area well suited to the unique perspective of medical anthropologists. In this article we present an analytical framework for contrasting patient and provider goals, strategies, and evaluation criteria in chronic illness management, using examples from research on type 2 diabetes care in South Texas. This approach goes beyond contrasting patient and provider concepts and explanations of the illness itself and examines their contrasting views within the dynamic process of long-term care. This approach may prove especially useful for research aimed at a clinical audience, since it maintains a clinically relevant focus while giving serious consideration to the patient's perspective.

Mismanaging prescription medications among rural elders: the effects of socioeconomic status, health status, and medication profile indicators

PURPOSE

This study assessed the extent to which community-dwelling rural older adults mismanage their prescription medication regimens and predicted mismanagement of medications from selected socioeconomic, health status, and medication profile characteristics.

DESIGN AND METHODS

Personal interviews with 499 community-dwelling adults aged 66 and over taking at least one prescription medication and living in a rural region of the Southeast. With approximately equal numbers of African American and white men and women, the SUDAAN multiple logistic regression procedure was used to predict the mismanagement of prescription medications.

RESULTS

The mismanagement of prescribed medication regimens is relatively common among older adults. Those more likely than others to mismanage their regimens are African American, younger, in poorer mental health, with more acute care physician visits, and those who find payment for their medications to be problematic.

IMPLICATIONS

The implications of the findings for what is known about the self-modification of drug regimens, targeting prescription drug cost benefits or interventions, and the limitations of the study are discussed.

Herbs, prayer, and insulin. Use of medical and alternative treatments by a group of Mexican American diabetes patients

BACKGROUND

Clinicians are often concerned that use of alternative treatments by Mexican American patients with diabetes competes with medical treatment. We examined the use and evaluation of alternative treatments for diabetes by a sample of these patients.

METHODS

Following a descriptive qualitative design, a convenience sample of 43 low-income Mexican Americans with type 2 diabetes were interviewed. We analyzed interview transcripts for alternative treatments named, patterns of use, evaluation of those treatments, and the use of biomedical approaches. We crosschecked the results for interrater reliability.

RESULTS

Herbs were mentioned as possible alternative treatments for diabetes by 84% of the patients interviewed. However, most had never or rarely tried herbs and viewed them as supplemental to medical treatments. Most said prayer influences health by reducing stress and bringing healing power to medicines. None used curanderos (traditional healers) for diabetes. Most actively used biomedical treatments and were less actively involved in alternative approaches. Statistical tests of association showed no competition between biomedical and alternative treatments, and alternative treatment activity tended to be significantly lower than biomedical. Most study participants emphasized medical treatment and only used alternative treatments as secondary strategies. Those patients very actively using alternative approaches also tended to be very actively using biomedical methods; they were using all resources they encountered.

CONCLUSIONS

Traditional attitudes and beliefs were not especially important to the patients in this study and presented no barriers to medical care. For these patients, it also cannot be assumed that belief in alternative treatments and God's intervention indicate fatalism or noncompliance but instead require consideration of individual treatment behaviors.

Contrasting patient and practitioner perspectives in type 2 diabetes management

Studies of self-care behaviors in the management of type 2 diabetes often focus on patient knowledge and motivation, without considering the role of practitioner orientations. Using an exploratory descriptive design, we conducted open-ended interviews with 51 type 2 diabetes patients and 35 practitioners from clinics in San Antonio and Laredo, Texas. We found critical differences between patient and practitioner goals, evaluations, and strategies in diabetes management, especially regarding such key concepts as "control" and "taking care of self". Practitioners' perspectives are rooted in a clinical context, emphasizing technical considerations, whereas patients' perspectives exist within a life-world context and foreground practical and experiential considerations. These result in very different approaches to treatment. Practitioners, presuming failed treatment indicates uncooperativeness, try to inform and motivate patients. The patients we interviewed, however, understood and were committed to type 2 diabetes self-care, but lacked full access to behavioral options due to their poverty and limited social power.

Abnormal Pap screening among Mexican-American women: impediments to receiving and reporting follow-up care

PURPOSE/OBJECTIVES

To understand impediments to receiving and reporting timely follow-up care for abnormal Pap tests among Hispanic women.

DESIGN

Descriptive, qualitative.

SETTING

A federally funded cancer screening clinic in urban South Texas.

SAMPLE

11 Mexican/Mexican-American women over 40 years old who appear in clinic records as "lapsed" in follow-up and 5 clinic staff members.

METHODS

Semistructured, qualitative interviews regarding staff and patient concepts about cancer, cancer screening, and follow-up. Abstraction of patients' clinic charts.

MAIN RESEARCH VARIABLES

Factors associated with women being classified as "lapsed" in follow-up care for abnormal Pap tests.

FINDINGS

Only two patients had no follow-up, while nine eventually had follow-up, either elsewhere or after several missed appointments. Contrary to expectations, poor knowledge, lack of social support, and lack of availability of care were not factors impeding follow-up. Reluctance to be examined by a male practitioner, lack of flexibility in scheduling clinic appointments, and poor staff communication regarding appointments and the seriousness of the condition were all influences negatively affecting follow-up behavior. Nevertheless, these women went to significant lengths to comply with follow-up recommendations.

CONCLUSIONS

The classification of patients' follow-up behavior as "lapsed" was not attributable to culturally based beliefs and attitudes, nor lack of knowledge and motivation, but was primarily the result of institutional features such as scheduling and record-keeping practices and policies.

IMPLICATIONS FOR NURSING PRACTICE

More thorough evaluation of actual behaviors would ensure more accurate assessment of follow-up behavior in this group. More female practitioners, better communication of appointments and of the seriousness of the condition, and more flexible scheduling options would reduce the difficulty these Hispanic patients encountered in having timely follow-up care.

Moral reasoning and the meaning of cancer: causal explanations of oncologists and patients in southern Mexico

Moral themes were a striking feature of the causal explanations for female cancers discussed by oncologists and patients in an ethnographic study of hospital-based cancer care in southern Mexico. These explanations integrate general biomedical explanations with everyday expectations and experiences, giving meaning to otherwise arbitrary events. Analysis of case examples shows that causal models incorporate local constructs about what constitutes a virtuous life, especially in terms of class-and gender-based values. Although patients and physicians draw on similar concepts of moral order, they apply these constructs in distinct ways. Because physicians' explanations are necessarily framed in terms of object, their causal stories employ generalized presumptions about how categories of persons behave (e.g., women, the lower class). In contrast, patients' explanations are framed in terms of subject; they are based on the specific details of their personal history. The article examines the distinct perspectives of physicians and patients, and provides an illustration of how biomedical culture articulates with the local moral constructs of a particular community.

Management of sexually transmitted disease by surgeons

The management of 63 patients diagnosed by surgeons as having sexually transmitted disease (STD) was audited. A diagnosis of STD was made in 51 (81%) of patients without taking a sexual history. Only 2 (3%) patients were referred to genitourinary medicine (GUM). Appropriate microbiological specimens were obtained from only two of 52 (4%) patients diagnosed with either pelvic inflammatory disease (PID) or epididymo-orchitis. Reliance was placed on inappropriate specimens in 22 (42%). There was widespread use of inappropriate antibiotics. The management of sexually transmitted disease by surgeons was very poor. These patients should all be referred to genito-urinary medicine.

Porque me tocó a mi? Mexican American diabetes patients' causal stories and their relationship to treatment behaviors

This paper reports findings from an ethnographic study of self-care behaviors and illness concepts among Mexican-American non-insulin dependent diabetes mellitus (NIDDM) patients. Open-ended interviews were conducted with 49 NIDDM patients from two public hospital outpatient clinics in South Texas. They are self-identified Mexican-Americans who have had NIDDM for at least 1 yr, and have no major impairment due to NIDDM. Interviews focused on their concepts and experiences in managing their illness and their self-care behaviors. Clinical assessment of their glucose control was also extracted from their medical records. The texts of patient interviews were content analyzed through building and refining thematic matrixes focusing on their causal explanations and treatment behaviors. We found patients' causal explanations of their illness often are driven by an effort to connect the illness in a direct and specific way to their personal history and their past experience with treatments. While most cite biomedically accepted causes such as heredity and diet, they elaborate these concepts into personally relevant constructs by citing Provoking Factors, such as behaviors or events. Their causal models are thus both specific to their personal history and consistent with their experiences with treatment success or failure. Based on these findings, we raise a critique of the Locus of Control Model of treatment behavior prevalent in the diabetes education literature. Our analysis suggests that a sense that one's own behavior is important to the disease onset may reflect patients' evaluation of their experience with treatment outcomes, rather than determining their level of activity in treatment.

How patients adapt diabetes self-care recommendations in everyday life

BACKGROUND

Our study explored behavioral factors affecting what patients with type 2 diabetes do for self-care and why they do it. The findings were used to develop clinical recommendations to improve intervention strategies.

METHODS

Interviewers, using open-ended questions, explored patients' own perceptions and assessments of self-care behaviors. The fifty-one subjects were self-identified Mexican Americans who had type 2 diabetes for at least 6 months, and had no major impairment as a result of this diabetes. Texts of patient interviews were analyzed by building and refining matrixes to display and compare central themes regarding treatment strategies and their contexts.

RESULTS

All patients were trying to control their diabetes, but none of them followed recommendations completely. Instead, they adapted self-care behaviors to the exigencies of everyday life. Key factors influencing patients' treatment choices were: (1) the belief in the power of modern medicine; (2) the desire to act and feel "normal"; (3) the desire to avoid physical symptoms; and (4) limited economic resources.

CONCLUSIONS

As patients apply treatment recommendations in the context of their everyday lives, they continually must make many small decisions affecting self-care behavior. The specific contexts of patients' lives, including their economic, educational, and cultural circumstances, determine how the generalized principles of type 2 diabetes management are implemented. Clinical strategies must be responsive to these circumstances in order to enable patients to make appropriate decisions when adapting their self-care behaviors to their own situations.

Endoscopic screening of relatives of patients with colorectal cancer

BACKGROUND

The risk of colorectal cancer is higher among relatives of those affected. The neoplastic yield reported from screening such individuals varies enormously between studies and depends on the age and strength of the family history of those screened.

AIMS

To ascertain the neoplastic yield of endoscopic screening of first degree relatives of patients with colorectal cancer by age and familial risk.

SUBJECTS

A total of 330 individuals with a family history of colorectal cancer.

METHOD

Endoscopic screening conducted according to a protocol.

RESULTS

Adenomas were found in 12%, and adenomas larger than 1 cm in 8%, of "high risk" individuals screened primarily by colonoscopy. Of those with neoplasia, 26% had lesions at or proximal to the splenic flexure. Neoplasia was found in 9.5% of individuals at lower familial risk, screened primarily by 60 cm flexible sigmoidoscopy, 4% of whom had neoplasia larger than 1 cm in size or cancer. Neoplastic yield was greatest in the fourth and fifth decades in those at highest risk, but increased with age in those at lower risk.

CONCLUSIONS

For individuals with two or more first degree relatives, or relatives who have developed colorectal cancer at a young age, colonoscopy appears to be the only satisfactory method of screening, but 60 cm flexible sigmoidoscopy may be useful in those at lower levels of risk.

NIDDM patients' fears and hopes about insulin therapy. The basis of patient reluctance

OBJECTIVE

This study examines NIDDM patients' attitudes toward insulin injections, the basis of these attitudes, and how they may affect patients' willingness to take insulin.

RESEARCH DESIGN AND METHODS

Forty-four low-income Mexican American NIDDM patients were interviewed using open-ended in-depth interviewing techniques. Transcripts were analyzed using techniques of content analysis. Data classification was cross-checked in analysis conferences and through a second researcher coding 50% of the cases, comparing the results, then resolving any discrepancies.

RESULTS

Patients' positive attitudes toward insulin focus on its efficacy and efficiency, the avoidance of complications, and feeling better and more energetic. Negative attitudes were much more frequently discussed and include "technical concerns": anxiety about the pain, proper techniques, and general hassles of taking injections; about hypoglycemic symptoms; and about insulin causing serious health problems; and "experimental concerns": sensing that the disease has progressed into a serious phase, that past treatment efforts have failed, and that the patient has not taken proper care. Attitudes were based on personal experience, observation, what others say, and interactions with health care professionals.

CONCLUSIONS

Results from the few published reports on NIDDM patients' attitudes about insulin from various cultural settings were consistent with our findings, indicating that these themes may be generally applicable to a wider population. It is recommended that health care providers take care to avoid unwitting promotion of negative attitudes toward insulin and actively elicit and respond to patient attitudes to reduce reluctance to take the medication.

Chemical and immunological testing for faecal occult blood in screening subjects at risk of familial colorectal cancer

BACKGROUND

People with a family history of colorectal cancer have an increased risk of the disease themselves. Many centres are advocating family history screening by endoscopy.

AIMS

The performance of chemical and immunological faecal occult blood tests (Haemoccult and Hemeselect) in 212 subjects with a family history of colorectal cancer was assessed.

RESULTS

Both Hemeselect and Haemoccult were positive in the only patient with colorectal cancer. Hemeselect was more sensitive than Haemoccult for adenomas (40% compared with 20%) (adenomas larger than 1 cm 75% compared with 50%). No additional abnormality was detected by the addition of Haemoccult or Hemeselect to 60 cm flexible sigmoidoscopy in screening people at lower levels of familial risk. A false positive rate of 16% for Hemeselect resulted in a high proportion of additional colonoscopies in this group.

CONCLUSIONS

At present faecal occult blood tests are not sufficiently sensitive or specific to replace endoscopy in screening people at risk of familial colorectal cancer.

Faecal occult blood testing and colonoscopy in the surveillance of subjects at high risk of colorectal neoplasia

Colonoscopy is the established method of surveillance of subjects at high risk of developing colorectal neoplasia but the procedure is expensive, time consuming and occasionally hazardous. Faecal occult blood tests can be prepared at home and are cheap, simple and safe. Hemeselect is an immunological faecal occult blood test that is more sensitive for colorectal cancer than Haemoccult. The aim of this study was to determine the sensitivity of the Hemeselect test for asymptomatic colorectal neoplasia in subjects at high risk of the disease who were undergoing colonoscopy, thus assessing its suitability as an alternative means of screening high-risk groups. A total of 919 asymptomatic subjects were asked to complete Hemeselect tests. These were completed satisfactorily by 808 individuals (compliance rate 88 per cent) and were positive in 164 patients (20 per cent). At colonoscopy 11 cancers were detected in ten patients (seven Hemeselect positive) and 36 (16 Hemeselect positive) had at least one adenoma 1 cm or more in diameter. The test sensitivites of Hemeselect for carcinoma and large (1 cm or more) adenomas were 70 and 44 per cent respectively. In a subset of 417 subjects who also completed Haemoccult tests, the sensitivities were 33 and 18 per cent. Hemeselect specificity is 88 per cent compared with 98 per cent for Haemoccult. While the sensitivity of Hemeselect is higher than that of Haemoccult, it is still insufficient to replace colonoscopy in high-risk groups.

Wheat fibre, lactulose and rectal mucosal proliferation in individuals with a family history of colorectal cancer

In a single-blind study 38 individuals at increased risk of developing colorectal cancer because of a family history of the disease were randomized to take 10.5 g wheat fibre (Trifyba) or 60 ml lactulose daily for 12 weeks. Rectal biopsies were taken before and after treatment and rectal mucosal proliferation was measured by the crypt cell production rate (CCPR). The mean(s.d.) CCPR was significantly lower in those taking wheat fibre after 12 weeks (7.2(3.4) crypt cells per crypt per h) compared both with values obtained before treatment with wheat fibre (10.2(5.1) crypt cells per crypt per h; P = 0.02) and after treatment with lactulose (9.4(3.8) crypt cells per crypt per h; P = 0.05). Proliferation in the lactulose group was not significantly different at 12 weeks compared with the value obtained before treatment. This study confirms an antiproliferative effect of wheat fibre in a group of high-risk individuals.
