Ethnomedical (folk) remedies for childhood asthma in a mainland Puerto Rican community

Isolation and Identification of Bioactive Compounds from Bidens spp. Using HPLC-DAD and GC-MS Analysis and Their Biological Activity as Anticancer Molecules

The genus Bidens a member of family Compositae, is widely documented as an ethno-medicinally important genus of plants. In the present study, anticancer potential of three ethno-medicinally important species i.e., B. bipinnata, B. biternata and B. pilosa were tested. For in-vitro evaluation, an MTT (Thiazolyl blue tetrazolium bromide) assay was performed against cervical cancer cells (HeLa), hepatocellular carcinoma (HepG), and adenocarcinoma human alveolar basal epithelial cells (A549). For in vivo evaluation, Artemia salina, Danio rerio, and Caenorhabditis elegans were used. Among all the tested extracts, the ethanol extract of B. biternata appeared to have highest anticancer activity, and the compounds responsible for this activity were identified to be Tris (2,4-di-tert-butylphenyl), 4-hydroxy-2,4′-dimethoxychalcone, and 2,4-di-tert-butylphenol. This is the first report of the isolation of Tris (2,4-di-tert-butylphenyl) phosphate from the genus Bidens and the first report of 4-hydroxy-2,4′-dimethoxychalcone and 2,4-di-tert-butylphenol from B. biternata. Among the isolated compounds, 4-hydroxy-2,4′-dimethoxychalcone showed the highest anticancer activity with an LD50 value of 236.7 µg/mL. Therefore, this compound carries promising potential for being established as a pharmaceutical for chemoprevention and chemotherapy.

[Cultivation and use of medicinal plants and association with reporting of childhood asthma: A case-control study in the Bogotá savanna]

Introduction

The prevalence of childhood asthma has increased in recent years. The World Health Organization has called for conducting research exploring the role of traditional medicine and medicinal plants in respiratory disease control.

Objective

To identify the relationship between the prevalence of childhood asthma and traditional care of the respiratory system, including cultivation and use of medicinal plants.

Methods

We conducted an observational, analytic, case-control study that included children 2 to 14 years old who used official health services in eight municipalities near Bogota between 2014 and 2015. Cases were children diagnosed with asthma. We randomly selected the controls among the remaining patients of the same healthcare facilities. We applied an 18-question survey. The Mantel-Haenszel procedure identified significant associations using 95% confidence intervals.

Results

We surveyed the caretakers of 97 cases and 279 controls in eight municipalities. Some 23.4% (88/376) and 37.9% (142/375) reported using traditional remedies for fever control and common cold management, respectively. 8.8% (33/376) reported following traditional care during a common cold, 30.4% (114/375) reported growing medicinal plants at home, and 45% (166/369) reported using medicinal plants for health purposes in their household. Multivariate analysis showed that having and using medicinal plants at home is associated with a lower reporting of asthma (odds ratio 0.49; 95% confidence interval: 0.25 to 0.99).

Conclusions

Cultivating and using medicinal plants at home is associated with a lower reporting of childhood asthma. Researchers should consider the therapeutic, environmental, and cultural properties of medicinal plants to prevent respiratory diseases.

Evaluation of a Spanish language version of the Asthma Trigger Inventory

Background: Perceptions of asthma triggers provide important guidance for patients' disease management. A psychometrically valid instrument, the Asthma Trigger Inventory (ATI), is available in English and German language versions, however, a version in Spanish as major world language has been missing.Method: A Spanish-language version of the ATI was evaluated in 339 adult patients with asthma, 223 of these in Peru and 107 in the USA. Principal Component analysis (PCA) with Varimax rotation was used to identify coherent trigger domains across and within samples. Resulting subscales were evaluated for internal consistency.Results: PCA suggested differences in factor structures between sites. Whereas the USA sample largely replicated original factors for animal allergens, pollen allergens, physical activity, air pollution/irritants, infections, and psychology, the initial analysis of the Peru sample suggested substantial overlap of air pollution/irritant, infection, and allergen items. Subsequent analysis of an expanded research form of the ATI for the Peru site culminated in extraction of five factors related to psychology, climate/temperature, combined pollen and animal allergens, physical activity, and infection. Internal consistencies were in an acceptable to excellent range (α = 0.74 to 0.94). Additional free trigger responses confirmed the importance of climate variables for patients in Peru. Psychological triggers were reported by 26% (Peru) and 31% (USA) of patients.Conclusion: Coherent trigger domains are readily identified and measured reliably by a Spanish-language ATI version. However, factor structures vary between samples from different Hispanic/Latino cultural and geographic domains. Culturally adapted versions of this instrument are therefore required for Hispanic/Latino population studies.

Disparities in complementary alternative medicine use and asthma exacerbation in the United States

Background: Complementary and alternative medicines (CAM) are associated with poor asthma medication adherence, a major risk factor for asthma exacerbation. However, previous studies showed inconsistent relationships between CAM use and asthma control due to small sample sizes, demographic differences across populations studied, and poor differentiation of CAM types.Methods: We examined associations between CAM use and asthma exacerbation using a cross-sectional analysis of the 2012 National Health Interview Survey. We included adults ≥18 years with current asthma (n = 2,736) to analyze racial/ethnic differences in CAM use as well as the association between CAM use and both asthma exacerbation and emergency department (ED) visit for asthma exacerbation across racial/ethnic groups. We ran descriptive statistics and multivariable logistic regressions.Result: Blacks (OR = 0.63 [0.49-0.81]) and Hispanics (OR = 0.66 [0.48-0.92]) had decreased odds of using CAM compared to Whites. Overall, there was no association between CAM use and asthma exacerbation (OR = 0.99 [0.79-1.25]) but the subgroup of 'other complementary approaches' was associated with increased odds of asthma exacerbation among all survey respondents (1.90 [1.21-2.97]), Whites (OR = 1.90 [1.21-2.97]), and Hispanics (OR = 1.43 [0.98-2.09). CAM use was associated with decreased odds of an ED visit for asthma exacerbation (OR = 0.65 [0.45-0.93]). These associations were different among racial/ethnic groups with decreased odds of ED visit among Whites (OR = 0.50 [0.32-0.78]) but no association among Blacks and Hispanics.Conclusion: We found that both CAM use and the association between CAM use and asthma exacerbation varied by racial/ethnic group. The different relationship may arise from how CAM is used to complement or to substitute for conventional asthma management.

Spirituality among American Indians in Health and Disease: Culturally Appropriate Recommendations for Health Care Providers

There are close to 560 different tribes in the United States of America and to be able to understand the complexity of the different tribes and cultures, there is a need to understand that while most tribes have differences they share certain values. These differences do not, for the most part, conflict with some of the values we will discuss later in this article. They are mostly of language and cultural practices, but the basic values remain the same. Even though many of the American Indian tribes have been viewed as having become acculturated, many American Indians have retained ties to their culture through language, spiritual practices, and family. These spiritual values will be discussed in relation to infant care practice.

Latino Caregiver Coping With Children's Chronic Health Conditions: An Integrative Literature Review

In this study we examined research pertaining to how Latino caregivers cope with their children's chronic health conditions. An understanding of this topic could facilitate appropriate interventions by health care staff to promote optimal child health outcomes. In this integrative review we categorized 21 studies by publication characteristics, methodology, findings, and their focus on emotion-focused and/or problem-focused coping. Thirteen studies used a qualitative design. Five studies included fathers in the sample. Twelve studies investigated coping with child's asthma, primarily in Mexican or Puerto Rican families. Coping strategies utilizing religion/spirituality, alternate healing practices, family support, and education about the child's illness were identified. Language, cultural dissimilarities, receiving inadequate information about the child's health care, differences in health beliefs, and feeling disrespected by providers were frequently cited coping challenges. Addressing these barriers is imperative to enhance coping of caregivers. Inconsistencies in research samples regarding income, education, immigration, and acculturation histories make findings difficult to generalize; recommendations for further research are suggested.

Culture and Dehydration: A Comparative Study of Caída de la Mollera (Fallen Fontanel) in Three Latino Populations

A sunken soft-spot or fontanel is a sign for dehydration in infants. Around the world, folk illnesses, such as caída de la mollera in some Latin American cultures, often incorporate this sign as a hallmark of illness, but may or may not incorporate re-hydration therapies in treatment strategies. This report describes a study of lay descriptions of causes, symptoms, and treatments for caída de la mollera in three diverse Latin American populations. A mixed-methods approach was used. Representative community-based samples were interviewed in rural Guatemala, Guadalajara, Mexico, and Edinburgh, Texas, with a 132 item questionnaire on the causes, susceptibility, symptoms, and therapies for caída de la mollera. Cultural consensus analysis was used to estimate community beliefs about caída. Interviews conducted in rural Guatemala (n = 60), urban Mexico (n = 62), and rural Texas on the Mexican border (n = 61) indicated consistency in thematic elements within and among these three diverse communities. The high degree of consistency in the illness explanatory models indicated shared beliefs about caída de la mollera in each of the communities and a core model shared across communities. However, an important aspect of the community beliefs was that rehydration therapies were not widely endorsed. The consistency in explanatory models in such diverse communities, as well as the high degree of recognition and experience with this illness, may facilitate communication between community members, and health care providers/public health intervention planners to increase use of rehydration therapies for caída de la mollera. Recommendations for culturally informed and respectful approaches to clinical communication are provided.

Minority mothers' healthcare beliefs, commonly used alternative healthcare practices, and potential complications for infants and children

PURPOSE

Complementary and alternative healthcare practices have increased substantially in the United States especially with low-income ethnic minority mothers. These mothers often have provider mistrust, language barriers, differing health belief systems, and as a result are less likely to seek preventive health screening, access healthcare services, and use alternative remedies for their infants and children that are potentially harmful or lethal. Therefore, the purpose of this article is to examine healthcare beliefs, commonly used alternative healthcare practices, and their potential complications for infants and children.

DATA SOURCES

A search of CINAHL and PubMed (1980-2012) was conducted using the following terms: alternative healthcare practice, mothers' health beliefs, cultural health beliefs, folk remedies, and infant health practices.

CONCLUSION

Given the changing U.S. population and an increasing immigrant population, examining alternative healthcare practices mothers use for their infants and children is especially important for providers in addressing healthcare for this group.

IMPLICATIONS FOR PRACTICE

The use of alternative healthcare practices is rarely discussed by parents with healthcare providers for fear of disapproval. When interviewing ethnic minority mothers and caregivers questions should include the use of alternative healthcare practices for infants and children and information regarding the potential dangers should be provided to them.

The adolescent with asthma

The adolescent with asthma experiences a period of physical and psychosocial changes that affect their health and well-being. Overall, adolescents with asthma are at increased risk for asthma morbidity and death. Increased rates of depression and anxiety, for the adolescent and their caregivers, can lead to non-adherence to their medical regimens, poor symptom control, and poor treatment outcomes. Contextual factors, such as race, ethnicity, and living situation, affect the prevalence, morbidity, and mortality for the adolescent with asthma. These factors also affect the transition process for adolescents entering adult medical care. An overview is presented of how the adolescent with asthma differs and how healthcare providers can promote effective asthma management and better asthma control.

Complementary and alternative medicine use and adherence to asthma medications among Latino and non-Latino white families

OBJECTIVE

The current study sought to evaluate patterns of complementary and alternative medicine (CAM) use in a sample of Latino and non-Latino white (NLW) children with asthma to determine whether parental beliefs about conventional medications and barriers to obtaining these medications were related to CAM use and to assess whether CAM use was associated with decreased adherence to controller medications.

METHODS

Participants included 574 families of children with asthma from NLW, Puerto Rican (PR), and Dominican backgrounds from Rhode Island (RI) and from Island PR. All parents completed a brief checklist of barriers to medication use and an assessment of CAM approaches. A subsample of 259 families had controller medication use monitored objectively for approximately 1 month by MDILog (fluticasone propionate), TrackCap (montelukast), or dosage counter (fluticasone/salmeterol combination).

RESULTS

Prevalence of CAM use was high among Latino families. Perceived barriers to obtaining medication were related to increased CAM use in PR families from RI. Elevated medication concerns were positively associated with CAM use among NLW and Island PR families. CAM use was positively related to objective adherence within NLW families, and unrelated in other groups.

CONCLUSIONS

CAM use is common among Latino families with asthma. Among some families, CAM use may be initiated as a way to cope with barriers to obtaining medication or when parents have concerns about conventional medications. Families who report CAM use do not appear to be substituting CAM for conventional asthma medication.

Intercultural health and ethnobotany: how to improve healthcare for underserved and minority communities?

ETHNOPHARMACOLOGICAL RELEVANCE

The present conceptual review explores intercultural healthcare--defined as the integration of traditional medicine and biomedicine as complementary healthcare systems--in minority and underserved communities. This integration can take place at different levels: individuals (patients, healers, biomedical healthcare providers), institutions (health centers, hospitals) or society (government policy).

BACKGROUND

Contemporary ethnobotany research of traditional medicine has primarily dealt with the botanical identification of plants commonly used by local communities, and the identification of health conditions treated with these plants, whereas ethnopharmacology has focused on the bioactivity of traditional remedies. On the other hand, medical anthropology seems to be the scholarship more involved with research into patients' healthcare-seeking itineraries and their interaction with traditional versus biomedical healthcare systems. The direct impact of these studies on public health of local communities can be contested.

AIM OF THE REVIEW

To compare and discuss the body of scholarly work that deals with different aspects of traditional medicine in underserved and minority communities, and to reflect on how gaps identified in research can be bridged to help improve healthcare in these communities.

KEY FINDINGS

The literature covers a broad range of information of relevance to intercultural healthcare. This information is fragmented across different scientific and clinical disciplines. A conceptual review of these studies identifies a clear need to devote more attention to ways in which research on traditional medicine can be more effectively applied to improve local public health in biomedical resource-poor settings, or in geographic areas that have disparities in access to healthcare.

CONCLUSIONS

Scholars studying traditional medicine should prioritize a more interdisciplinary and applied perspective to their work in order to forge a more direct social impact on public health in local communities most in need of healthcare.

Psychosocial factors and behavioral medicine interventions in asthma

OBJECTIVE

This review examines the evidence for psychosocial influences in asthma and behavioral medicine approaches to its treatment.

METHOD

We conducted a systematic review of the literature on psychosocial influences and the evidence for behavioral interventions in asthma with a focus on research in the past 10 years and clinical trials. Additional attention was directed at promising new developments in the field.

RESULTS

Psychosocial factors can influence the pathogenesis and pathophysiology of asthma, either directly through autonomic, endocrine, immunological, and central nervous system mechanisms or indirectly through lifestyle factors, health behaviors, illness cognitions, and disease management, including medication adherence and trigger avoidance. The recent decade has witnessed surging interest in behavioral interventions that target the various pathways of influence. Among these, self-management training, breathing training, and exercise or physical activation programs have proved particularly useful, whereas other essential or promising interventions, such as smoking cessation, dietary programs, perception and biofeedback training, and suggestive or expressive psychotherapy, require further, more rigorous evaluation. Given the high comorbidity with anxiety and mood disorders, further evaluation of illness-specific cognitive behavior therapy is of particular importance. Progress has also been made in devising community-based and culturally tailored intervention programs.

CONCLUSION

In concert with an essential medication treatment, behavioral medicine treatment of asthma is moving closer toward an integrated biopsychosocial approach to disease management.

The challenge of asthma in minority populations

The burden and disparity of asthma in race/ethnic minorities present a significant challenge. In this review, we will evaluate data on asthma epidemiology in minorities, examine potential reasons for asthma disparities, and discuss strategies of intervention and culturally sensitive care.

Ethnic differences in caregiver quality of life in pediatric asthma

OBJECTIVE

The aim of this study was to determine ethnic and site differences in quality of life (QOL) in a sample of Latino (Puerto Rican [PR] and Dominican) and non-Latino white caregivers of children with asthma in mainland US and Island PR. We also investigated ethnic and site differences in associations between caregiver QOL and indicators of asthma morbidity.

METHOD

Seven hundred and eighty-seven children with asthma (7-16 years of age) and their primary caregivers participated in the study. Primary caregivers completed a measure of QOL, child asthma control, and emergency department utilization, among other measures.

RESULTS

Ethnic and site differences were found on total QOL scores (ΔF(1,783) = 29.46, p < .001). Island PR caregivers reported worse QOL scores than Rhode Island (Rl) Latino and non-Latino white caregivers; Rl Latino caregivers reported significantly worse QOL scores than non-Latino white caregivers. In Rl Latino and Island PR children, worse caregiver QOL was associated with asthma that was not in control and with one or more emergency department visits.

CONCLUSION

Latino caregivers may be experiencing a greater level of burden related to their child's asthma than non-Latino white caregivers. Caregiver QOL in pediatric asthma may be a reflection of broader contextual stress that some Latino caregivers experience on a daily basis (e.g., cultural beliefs, acculturation). Future research should continue to investigate mechanisms that explain the burden associated with pediatric asthma in Latino families, as well as whether QOL assessments should consider the impact of everyday stressors on caregiver QOL in pediatric asthma.

Complementary and alternative medicine use and psychosocial outcomes among urban adolescents with asthma

Objective. Many adolescents with asthma use complementary and alternative medicine (CAM) for asthma symptom management. The purpose of this study was to investigate cross-sectional and longitudinal differences in psychosocial health outcomes between high and low CAM users among urban adolescents with asthma. Methods. Adolescents (Time 1: N = 151, Time 2: N = 131) completed self-report measures regarding the use of 10 CAM modalities, mental health, and health-related quality of life (HRQoL) following two clinic visits 1 year apart as part of a larger observational study. Multivariable regression analyses using backward elimination examined relationships between CAM use at Time 1 and outcomes at Time 1 and Time 2, controlling for key covariates and, in longitudinal analyses, Time 1 functioning. Results. Participants (M(age) = 15.8, SD = 1.85) were primarily African-American (n = 129 [85%]) and female (n = 91 [60%]) adolescents with asthma. High and low CAM users differed significantly in terms of several psychosocial health outcomes, both cross-sectionally and longitudinally. In cross-sectional multivariable analyses, greater frequency of praying was associated with better psychosocial HRQoL (R(2) = 0.22). No longitudinal relationships remained significant in multivariable analyses. Conclusions. Specific CAM techniques are differentially associated with psychosocial outcomes, indicating the importance of examining CAM modalities individually. Greater frequency of praying was cross-sectionally associated with better psychosocial HRQoL. When controlling for key covariates, CAM use was not associated with psychosocial outcomes over time. Further research should examine the effects of CAM use in controlled research settings.

Gerardo: asthma and cultural beliefs in a Latino family

Gerardo is an 8-year-old Latino boy who saw his primary care pediatrician with a second asthma exacerbation this year. His frustration with his illness was immediately apparent when he said, "I hate having to go to the nurse's office to take my albuterol!" His mother expressed concern that her son frequently refused to take his prevention medication for asthma, montelukast, each morning. When questioned about compliance with his inhaled steroid, his mother hesitated and then admitted that she discontinued the controller medication because she is afraid to "poison his body with so many chemicals." She consistently gave her son the inhaled steroid for 12 months, until care by the allergy specialist was unexpectedly transferred to a Spanish-speaking allergist. She complained that the new doctor is "cold and acts like a veterinarian, not a pediatrician." Gerardo is a first generation Mexican-American who was born in the United States to Spanish-speaking parents. There is no family history of asthma, although his mother fears that she may have contributed to Gerardo's condition. She explained that during pregnancy, she worked cleaning houses where she was exposed to many toxic household cleaners. She has always worried that by inhaling these fumes during pregnancy, she induced her son's asthma. Gerardo presented with his first episode of reactive airway disease at 9 months of age. His mother vividly recalled his high temperature, rapid breathing, and their ambulance ride to the hospital. He was hospitalized for 3 days, and he has not been hospitalized since. Allergy testing revealed sensitivity to weed pollen only. Gerardo sleeps with a nonallergenic pillow and bed cover. Gerardo's mother explained that 3 days before his current exacerbation, he was playing at an amusement park with his friends on a hot day. Gerardo and his friends ran through a large fountain. His mother reported that he was soaked in water and stated, "He knows that he will get sick with asthma if he gets wet!" She recalled that 3 years ago at a friend's birthday party, Gerardo abstained from running through the sprinklers with the other children without instruction from his parents. Since that event, she has trusted Gerardo to care for his "weak lungs." She is frustrated now with his regression in self-care.

Knowledge and use of ethnomedical treatments for asthma among Puerto Ricans in an urban community

PURPOSE

Puerto Ricans have higher lifetime and current asthma prevalence than other racial and ethnic groups in the United States. A great many Hispanics use ethnomedical therapies for asthma. This study elicited participant knowledge of ethnomedical therapies, developed a typology of the therapies, and considered whether some types are used or deemed efficacious based, in part, on information source.

METHODS

Eligible participants were randomly selected from the medical records of an inner-city primary care clinic serving a predominantly Hispanic community in Buffalo, New York. Thirty adult Puerto Ricans who had asthma or were care-givers of children with asthma were interviewed in person using a semistructured instrument. Qualitative data analysis followed a content-driven immersion-crystallization approach. Outcome measures were ethnomedical treatments for asthma known to participants, whether these treatments were used or perceived effective, and the participant's information source about the treatment.

RESULTS

Participants identified 75 ethnomedical treatments for asthma. Behavioral strategies were significantly more likely to be used or perceived effective compared with ingested and topical remedies (P <.001). Among information sources for ingested and topical remedies, those recommended by community members were significantly less likely to be used or perceived effective (P <.001) compared with other sources.

CONCLUSIONS

This sample of Puerto Ricans with a regular source of medical care was significantly more likely to use or perceive as effective behavioral strategies compared with ingested and topical remedies. Allopathic clinicians should ask Puerto Rican patients about their use of ethnomedical therapies for asthma to better understand their health beliefs and to integrate ethnomedical therapies with allopathic medicine.

The role of culture in health literacy and chronic disease screening and management

Cultural and language differences and socioeconomic status interact with and contribute to low health literacy, defined as the inability to understand or act on medical/therapeutic instructions. Health literacy is increasingly recognized as an important factor in patient compliance, cancer screening utilization, and chronic disease outcomes. Commendable efforts have been initiated by the American Medical Association and other organizations to address low health literacy among patients. Less work has been done, however, to place health literacy in the broader context of socioeconomic and cultural differences among patients and providers that hinder communication and compliance. This review examines cultural influences on health literacy, cancer screening and chronic disease outcomes. We argue that cultural beliefs around health and illness contribute to an individual's ability to understand and act on a health care provider's instructions. This paper proposes key aspects of the intersection between health literacy and culturally varying beliefs about health which merit further exploration.

Use of folk remedies among families of children hospitalised in Taiwan

AIMS

To describe the attitudes toward and the use of folk remedies among caregivers of children who were hospitalised in Taiwan.

BACKGROUND

Parents incorporate folk remedies into the care of sick children in many cultures, including Taiwan. Twelve common folk remedies are commonly used in the Taiwanese culture for the care of sick children.

DESIGN

The study employed a descriptive, exploratory design using survey methods. Participants were 92 caregivers (parents) whose children were hospitalised for at least three days in a hospital in the middle district of Taiwan.

RESULTS

Sixty per cent of the participants used some form of folk remedies in the care of their hospitalised children. The most frequently used remedies were: spirit-calling (63%); carrying a cross or incense bag (47%), praying a Buddhist mantra (36%). There was a positive relationship between a positive attitude towards folk remedies and current use with children (p < 0.05). Logistic regression analysis revealed that parents' previous experience of using folk remedies (odds ratio = 0.272, p = 0.037), and parents' knowledge of the care of disease (odds ratio = 18.044, p = 0.015) were the strongest predictors of use of folk remedies. Almost three-fourths (73%) of all participants expected that health care providers would respect and not interfere with their use of folk remedies; 72% of parents stated that they would not tell healthcare providers about the use of folk remedies.

CONCLUSIONS

The majority of the parents of hospitalised children in Taiwan can be expected to use folk remedies for the purpose of psychological and spiritual support during child hospitalised.

RELEVANCE TO CLINICAL PRACTICE

Healthcare providers need to be aware of the folk remedies used within various cultural groups so that culturally appropriate and safe care can be provided for the child and family.

Beliefs and barriers to medication use in parents of Latino children with asthma

OBJECTIVE

Disparities in asthma outcomes exist between Latino and non-Latino white (NLW) children. We examined rates of medication use, medication beliefs, and perceived barriers to obtaining medication in US and island Puerto Rican parents of children with asthma.

HYPOTHESES

Island PR parents would report the lowest rates of controller medication use, followed by RI Latino and RI NLW parents; Latino parents would report more medication concerns than NLW parents; and Island PR parents would report the most barriers to medication use.

STUDY DESIGN

Five hundred thirty families of children with persistent asthma participated, including 231 Island PR, 111 RI NLW, and 188 RI Latino. Parents completed survey measures.

RESULTS

Group differences were found on reported use of ICS (X(2) = 50.96, P < 0.001), any controller medication (X(2) = 56.49, P < 0.001), and oral steroids (X(2) = 10.87, P < 0.01). Island PR parents reported a greater frequency of barriers to medication use than the other two groups (X(2) = 61.13, P < 0.001). Latino parents in both sites expressed more medication concerns than NLW parents (F = 20.18, P < 0.001). Medication necessity was associated with ICS use in all three groups (all P's < 0.01). Medication concerns were positively associated with ICS use in PR only (OR = 1.64, P < 0.05).

CONCLUSIONS

Differences in medication beliefs and the ability to obtain medications may explain the reported disparity in controller medication use. Further studies are needed to evaluate these obstacles to medication use.

Addressing asthma health disparities: a multilevel challenge

Substantial research has documented pervasive disparities in the prevalence, severity, and morbidity of asthma among minority populations compared with non-Latino white subjects. The underlying causes of these disparities are not well understood, and as a result, the leverage points to address them remain unclear. A multilevel framework for integrating research in asthma health disparities is proposed to advance both future research and clinical practice. The components of the proposed model include health care policies and regulations, operation of the health care system, provider/clinician-level factors, social/environmental factors, and individual/family attitudes and behaviors. The body of research suggests that asthma disparities have multiple, complex, and interrelated sources. Disparities occur when individual, environmental, health system, and provider factors interact with one another over time. Given that the causes of asthma disparities are complex and multilevel, clinical strategies to address these disparities must therefore be comparably multilevel and target many aspects of asthma care. Several strategies that could be applied in clinical settings to reduce asthma disparities are described, including the need for routine assessment of the patient's beliefs, financial barriers to disease management, and health literacy and the provision of cultural competence training and communication skills to health care provider groups.

Don't ask, don't tell: parental nondisclosure of complementary and alternative medicine and over-the-counter medication use in children's asthma management

INTRODUCTION

Parent-health care provider (HCP) communication is an important component of pediatric asthma management. Given the high prevalence of complementary and alternative medicine (CAM) and over-the-counter (OTC) medication use among this population, it is important to examine parental nondisclosure of these asthma management strategies.

METHOD

One-time interview and 1-year retrospective medical record review with 228 parents of 5- to 12-year-old children with asthma enrolled from six pediatric primary care practices examining parental nondisclosure of CAM and OTC medication use, reasons for nondisclosure, medical record documentation of CAM usage, and association between parent-HCP relationship and nondisclosure.

RESULTS

Seventy-one percent of parents reported using CAM and/or OTC medication for children's asthma management, and 54% of those parents did not disclose usage. Seventy-five percent "did not think" to discuss it. Better parent-HCP relationship led to decreased nondisclosure.

DISCUSSION

HCPs can play an important role in creating an environment where parents feel comfortable sharing information about their children's asthma management strategies in order to arrive at a shared asthma management plan for the child, leading to improved asthma health outcomes.

Complementary and alternative medicine for children's asthma: satisfaction, care provider responsiveness, and networks of care

We explain why some caretakers opt for alternative medicine for the treatment of children's asthma whereas others do not. In the past 15 years, asthma care has been standardized, with clinical practice guidelines centered on advanced pharmacological regimes. Clinicians argue that with proper biomedical treatment and environmental control, asthma should be a manageable chronic disease. Yet many patients forego available pharmacological treatments for alternative medicine or complement prescribed drugs with unconventional treatments. On the basis of open-ended, in-depth qualitative interviews with 50 mothers of children with asthma, we argue that the experience with biomedical treatments, social influence in mother's network of care, concerns about adverse and long-term effects, health care providers' responsiveness to such concerns, and familiarity with alternative treatments explain why some families rely on alternative medicine and others do not.

Complementary and alternative medicine use among Hispanics in the United States

OBJECTIVE

To review the use of complementary and alternative medicine (CAM) in Hispanics in the US and highlight the modalities most likely to be unfamiliar to healthcare practitioners.

DATA SOURCES

A search of the literature published in English and a subsequent bibliographic search were conducted using MEDLINE, International Pharmaceutical Abstracts, EMBASE, Cumulative Index of Nursing and Allied Health Literature, and Manual Alternative and Natural Therapy Index System (1980-March 2007). Primary search terms included, but were not limited to, Hispanic, Latino, complementary and alternative medicine, and dietary supplements. Studies that assessed or evaluated the use of CAM in the Hispanic population were reviewed. Articles that included both Hispanics and non-Hispanics were also included.

STUDY SELECTION AND DATA EXTRACTION

The literature search yielded 42 articles focused on the use of CAM by Hispanics. Survey was the most common method used in these studies, although some hybrid interviews were also conducted.

DATA SYNTHESIS

Hispanics were identified homogenously in some studies and more correctly as a heterogeneous population in others. Some trials examined overall CAM use, whereas others looked at specific dietary supplements and herbs. Most reports found a higher than expected rate of CAM use in Hispanics (50-90%). A number of products potentially unfamiliar to healthcare practitioners, such as linden, sapodilla, and star anise, were reported as commonly used in several studies. Many studies were limited by the sample size or use of only one Hispanic subgroup.

CONCLUSIONS

Hispanics use a wide range of CAM therapies, including several that may be unfamiliar to healthcare practitioners. Understanding the rationale, motivations, and history of Hispanics' use of CAM will enhance the cultural competence of healthcare professionals and help address these patients' medical needs.

Child health care decision making and experiences of Caribbean women

INTRODUCTION

The purposes of this study were to (a) obtain data about the child health care decision making and practices of immigrant English-speaking women from the Caribbean region and (b) describe their experiences with the U.S. health care system and providers of care.

METHOD

A qualitative design with purposeful sampling was used. Data were obtained from 12 women through focus group interviews.

RESULTS

Three descriptive categories were identified: child/family focus, childhood illnesses and remedies, and relationships with providers. Findings included use of "parallel utilization" practices by the caretakers; use of herbs and other alternative practices; a strong informal social support network within the community; and frustration with and lack of trust in health care providers.

DISCUSSION

Immigrant children and children of immigrant Caribbean adults are a vulnerable population that may be at risk for poor health and mental health outcomes when receiving care from multiple or inconsistent providers, when providers are unaware of folk practices administered to these children by caretakers, and because of a lack of research about the efficacy of folk medicines used in children either alone or in combination with prescribed Western medicines.

Complementary and alternative medicine use in asthma: who is using what?

Consumer interest in complementary and alternative medicine (CAM) has grown dramatically in Western countries in the past decade. However, very few patients volunteer information about CAM use unless directly questioned by their health-care practitioner. Therefore, by being informed about the prevalence and modality of CAM use for asthma, as well as characteristics of users, health-care practitioners may be better able to identify patients who use CAM. In turn, this may facilitate proactive discussion and optimization of the patient's overall asthma management. This review aims to summarize the current knowledge about use of CAM by people with asthma, and to assess the applicability of the available studies to the broader asthmatic population. Computerized literature searches were conducted on Medline, Embase, Cochrane and Allied and Complementary Medicine (AMED) databases from their inception to 13 April 2005. Search terms included: complementary medicine/therapies, alternative medicine/therapies and asthma. The bibliographies of accessible articles were searched for further papers. Seventeen studies have examined the use of CAM by people with asthma. The reported level of use for adults ranged from 4% to 79%, and for children from 33% to 89%. Among the most commonly used CAMs were: breathing techniques, herbal products, homeopathy and acupuncture. There is no strong evidence for effectiveness for any of these modalities. There is little consistency among available prevalence studies making conclusions difficult. Nevertheless, the high rates of CAM use reported in some studies indicate that CAM use should be taken into account when managing patients with asthma.

Disparities in complementary and alternative medical therapy recommendations for children in two different socioeconomic communities

OBJECTIVE

To compare the content, quality, and cost of recommendations for children made by complementary and alternative medicine (CAM) retailers within 2 New York City neighborhoods of divergent socioeconomic status (SES).

METHODS

Posing as consumers, researchers sought recommendations from CAM retailers for 2 clinical scenarios: 1) a febrile 6-week-old and 2) a 4-year-old with an upper respiratory infection (URI). All retailers selling CAM therapies outside the direction of a licensed provider within East Harlem (EH) and the Upper East Side (UES) were eligible and mapped. The febrile infant scenario was posed at sites in business in March (n = 23) and the URI scenario at sites that remained in business in April (n = 20) of 2004.

RESULTS

In response to the febrile infant scenario, 33% of UES retailers referred to a MD, 0% to the emergency department, and 47% made other recommendations-of which 43% were not indicated. In EH, 50% referred to a MD, 5% to the emergency department, and 37% made other recommendations. The mean price of UES recommendations was Dollars 9.66, whereas EH was Dollars 2.33 (P = .04). In response to the URI scenario, 93% of UES and 83% of EH retailers made recommendations. The mean price of UES recommendations was Dollars 10.55 while EH was Dollars 4.26 (P = .002).

CONCLUSIONS

Complementary and alternative medicine retailers made numerous recommendations for children, including some that were contraindicated for age. East Harlem retailers tended to refer an infant with a potentially serious condition to the emergency department or to an MD and made less expensive recommendations than their UES counterparts.

Asthma in Hispanics in the United States

The Hispanic population in the United States is diverse in many respects. Although there is marked variation in the prevalence, morbidity, and mortality of asthma among Hispanic subgroups in the United States, these differences are poorly understood. Future stu-dies of asthma should include large samples of Hispanic subgroups that are well characterized in terms of self-reported ethnicity, country of origin, place of birth, area of residence, and indicators of socioeconomic status. Because a significant proportion of Hispanics live in poverty, public health interventions aimed at improving access to health care and housing conditions would have a major impact on reducing asthma morbidity among Hispanics in the United States.

Asthma disparities in the prevalence, morbidity, and treatment of Latino children

The paper reviews the existing research related to asthma disparities and frames the results of this research within a conceptual model modified from the Institute of Medicine model in order to explain asthma health disparities in Latino children in the USA. The model of pediatric asthma disparity presented is based on the conceptualization of health disparities as the result of a complex interaction of factors related to four main domains: the individual and family, the environment or context in which the child lives, the health-care system, and provider characteristics. Asthma disparities are discussed as they are reflected in the process of care (access and quality of treatment) and outcome (prevalence, morbidity, severity) experienced by Latino children. The potential mechanisms that may account for the asthma disparities documented as reflected by the conceptual model proposed are discussed. Finally, several suggestions for future research examining determinants that account for asthma disparities are examined.

Applying epidemiologic concepts of primary, secondary, and tertiary prevention to the elimination of racial disparities in asthma

Despite medical and scientific advances, racial and ethnic disparities persist in US asthma morbidity and mortality rates. Progress in the elimination of these disparities will involve disentangling the contribution of social constructs, such as race, socioeconomic status, and culture, from that of the physical environment and genetic susceptibility. One approach to reducing asthma disparities is through the traditional disease prevention stages of intervention. As such, primary prevention targets reductions in asthma incidence; secondary prevention is the mitigation of established disease and involves disease detection, management, and control; and tertiary prevention is the reduction of complications caused by severe disease. Once causative factors at each level of disease prevention are understood, this knowledge can be translated into clinical practice and public health policy.

Heterogeneity of childhood asthma among Hispanic children: Puerto Rican children bear a disproportionate burden

OBJECTIVES

To estimate differences in asthma prevalence among Hispanic subgroups and non-Hispanic children living in the United States and to explore the association between these differences and risk factors.

METHODS

Weighted logistic regression analyses of merged 1997 to 2001 National Health Interview Survey data were used to estimate the prevalence of asthma diagnosis and asthma attacks in a sample of 46511 children (age: 2-17 years) living in the 50 states and the District of Columbia.

RESULTS

Puerto Rican children had the highest prevalence of lifetime asthma (26%) and recent asthma attacks (12%), compared with non-Hispanic black children (16% and 7%, respectively), non-Hispanic white children (13% and 6%, respectively), and Mexican children (10% and 4%, respectively). Adjustment for asthma risk factors did not change these comparisons appreciably. Compared with non-Hispanic white children, the adjusted odds ratios (ORs) for a lifetime asthma diagnosis were 2.33 (95% confidence interval [CI]: 1.90-2.84) for Puerto Rican children, 1.16 (95% CI: 1.04-1.29) for non-Hispanic black children, and 0.90 (95% CI: 0.79-1.03) for Mexican children. Birthplace influenced the association between ethnicity and lifetime asthma diagnosis differently for Puerto Rican and Mexican children. Compared with United States-born non-Hispanic white children with United States-born parents, the adjusted ORs were 1.95 (95% CI: 1.48-2.57) for Puerto Rican children in families with the child and parent(s) born in the 50 states/District of Columbia and 2.50 (95% CI: 1.51-4.13) for island-born Puerto Rican children with island-born parents. The corresponding adjusted ORs for Mexican children were 1.05 (95% CI: 0.90-1.22) for families born in the 50 states/District of Columbia and 0.43 (95% CI: 0.29-0.64) for those born in Mexico. The results were similar for recent asthma attacks.

CONCLUSIONS

The appreciably higher asthma morbidity rates experienced by Puerto Rican children cannot be explained by sociodemographic and other risk factors measured in the National Health Interview Survey. The heterogeneity of asthma among Hispanic subgroups should be considered in developing effective public health prevention and intervention strategies.

The role of culture in families' treatment decisions for children with autism spectrum disorders

There is little information available about how and why parents of children with autism spectrum disorders (ASD) make decisions regarding which of the many available treatments to implement with their children. Given the lack of available information regarding treatment efficacy, it is likely that parents' beliefs about child development, interpretation of the symptoms of ASD, its etiology and course, and their experiences with the health system influence treatment decisions. This article addresses these issues within the context of cultural influences. We review the small body of existing literature regarding cultural influences on decisions regarding ASD and draw implications for the study and treatment of ASD from the larger body of literature on culture and other health conditions of childhood. In addition to examining the potential for differences in clinical presentation by culture and different experiences with the healthcare system, we use Kleinman's framework of questions for understanding the role of culture in the interpretation and treatment of ASD. These questions address interpretation of symptoms and beliefs about their cause, course, and treatment. Finally, we present specific language for clinicians to use in discussion with families with different cultural beliefs about the use of less traditional treatment strategies.

Asthma in Hispanics

Hispanic individuals trace their ancestry to countries that were previously under Spanish rule, including Mexico, large parts of Central and South America, and some Caribbean islands. Most--but not all--Hispanics have variable proportions of European, Amerindian, and African ancestry. Hispanics are diverse with regard to many factors, including racial ancestry, country of origin, area of residence, socioeconomic status, education, and access to health care. Recent findings suggest that there is marked variation in the prevalence, morbidity, and mortality of asthma in Hispanics in the United States and in Hispanic America. The reasons for differences in asthma and asthma morbidity among and within Hispanic subgroups are poorly understood but are likely due to the interaction between yet-unidentified genetic variants and other factors, including environmental tobacco smoke exposure, obesity, allergen exposure, and availability of health care. Barriers to optimal management of asthma in Hispanics in the United States and in Hispanic America include inadequate access to health care, suboptimal use of antiinflammatory medications, and lack of reference values for spirometric measures of lung function in many subgroups (e.g., Puerto Ricans). Future studies of asthma in Hispanics should include large samples of subgroups that are well characterized with regard to self-reported ethnicity, country of origin, place of birth, area of residence, and indicators of socioeconomic status. Because Hispanics are disproportionately represented among the poor in the United States, implementation of adequate access to health care and social reforms (e.g., improving housing conditions) would likely have a major impact on reducing asthma morbidity in this population.

Rubbing ointments and asthma morbidity in adolescents

OBJECTIVE

To determine the relationship between the use of rubbing ointments and asthma morbidity in adolescents.

DESIGN

Cross-sectional study.

SETTINGS/LOCATION

Inner-city high school in the Bronx, New York.

SUBJECTS

165 adolescents with asthma.

OUTCOME MEASURES

Asthma morbidity, defined as emergency department (ED) use for asthma in the past year and over the lifetime.

RESULTS

While 127 (77%) of subjects used albuterol as the first treatment for their last asthma attack, 18 (11%) used rubbing ointments. The rubs and albuterol groups were similar in asthma severity, mean age, gender, and ethnicity. However, subjects in the the rubs group were less likely than subjects in the albuterol group to have made an ED visit over the past 12 months or over their lifetime. Regression analysis revealed that, after controlling for asthma severity, use of rubs independently predicted less lifetime ED use.

CONCLUSIONS

After controlling for asthma severity, use of rubs by adolescents with asthma was associated with lower asthma morbidity as measured by ED use.

The use of folk remedies among children in an urban black community: remedies for fever, colic, and teething

BACKGROUND

Folk remedy use is universal, occurring in all cultures. Folk remedies have been and still are relied on in the black community. In this study, folk remedies refer to herbs, over-the-counter medications, and items traditionally used for cooking that are used to treat a variety of ailments.

OBJECTIVE

To identify folk remedies used to treat fever, colic, and teething among black children in Detroit, Michigan.

METHODS

Structured interviews were conducted with caregivers of healthy black children <2 years of age who were patients of the general pediatric clinic at Children's Hospital of Michigan. Descriptive analysis of the frequency distribution of the responses was performed.

RESULTS

One hundred seven caregivers agreed to participate. All participants were familiar with the use of folk remedies. Most caregivers learned of these remedies from their mothers or grandmothers. Older parents were more likely to use folk remedies, but there was no difference in remedy use among different levels of maternal education.

CONCLUSIONS

The knowledge and use of folk remedies were active in this black community. Their use seems to be cultural, rather than attributable to decreased access to health care. Physicians should be aware of these remedies, to educate families about remedies that may be harmful. Most remedies used pose no threat to health. In some cases, remedies may be blended with traditional medical treatments to ensure better patient compliance.

The development and establishment of a care map in children with asthma in Taiwan

BACKGROUND

It is often difficult to predict the timing and frequency of asthma attacks. In addition to interrupting the daily life of both the affected child and his/her family, asthma can also pose sudden danger to a child. Based on clinical observations, many asthma-affected children and their parents must constantly adjust themselves to the uncertainty of the disease, which leads to increased stress on the family. The use of care maps has demonstrated increased efficiency and effectiveness in the care of asthma patients from a variety of settings.

OBJECTIVE

We designed this study to construct and evaluate a care map for asthmatic children in Taiwan. Specific attention was placed on comparing the study and control subjects by parental knowledge of asthma, medication used for asthma, hospital readmission, and health care resource usage.

SUBJECTS AND METHODS

The care map was constructed by in-depth interviews with eight sets of parents of children with asthma. Forty-four parents of 42 asthma children were randomized into two groups in the Allergic Clinic of the Chang Gung Children's Hospital. The experimental group of 22 parents received individual instruction and training sessions in addition to the regular care provided to the control group of 22 parents.

RESULTS

Forty-two children with asthma were surveyed in this study. To examine the reliability and validity of a care map for children with asthma, a quantitative survey was conducted with 42 outpatient parents with asthmatic children. There was less emergency room attending rate in experimental group (6/month; p<0.05) The understanding of the disease was much improved in parents of experimental group (13.85+/-1.04 vs. 10.91+/-2.14; p<0.01). Furthermore, parents acquired a more positive attitude to asthma, and almost all of the control group had irregular follow-ups by a physician and had irregular use of medication.

CONCLUSION

This study emphasizes that a care map in children with asthma (CACM) can be used to educate parents in how to provide the best treatment plan for their children. This study also shows how a CACM can help parents train their children in the best behaviors during asthma attacks. Empathetic assessment and elimination of cultural barriers, a well-designed educational program, and a mutually developed treatment plan could significantly improve the quality of life for families and specific asthma outcomes.

Acculturation and Latino health in the United States: a review of the literature and its sociopolitical context

This chapter provides an overview of the concept of acculturation and reviews existing evidence about the possible relationships between acculturation and selected health and behavioral outcomes among Latinos. The effect of acculturation on Latino health is complex and not well understood. In certain areas-substance abuse, dietary practices, and birth outcomes-there is evidence that acculturation has a negative effect and that it is associated with worse health outcomes, behaviors, or perceptions. In others-health care use and self-perceptions of health-the effect is mostly in the positive direction. Although the literature, to date, on acculturation lacks some breadth and methodological rigor, the public health significance of findings in areas in which there is enough evidence justifies public health action. We conclude with a set of general recommendations in two areas-public health practice and research-targeted to public health personnel in academia, community-based settings, and government agencies.

Cultural influences on health care use: differences in perceived unmet needs and expectations of providers by Latino and Euro-American parents of children with special health care needs

This study compares service use, perceived unmet needs, and expectations of providers of Latino and Euro-American families of children with disabilities enrolled in a Title V Program. Eighty-four families and 20 providers participated in open-ended, semistructured, and structured interviews. Latino families underused Title V services (p <.001). The Latino families were more likely to cite unmet needs in the following areas: an unresolved health problem (p <.05), rehabilitation therapy programs (p <.001), or need for more information or a support group (p <.001). The Euro-American families cited unmet needs in the following areas: lack of day care (p <.001), respite services (p <.001), recreational programs (p <.001), and home health aides (p <.007). Textual analysis of open interviews revealed that the two groups of families had different expectations of providers. Latino cultural values play a role in these differences, creating barriers for effectively communicating with providers and for meeting children's needs.

Understanding pediatric inner-city asthma: an explanatory model approach

Explanatory models (EMs) for asthma among inner-city school-age children and their families were examined as a means of better understanding health behaviors. Children and parents were interviewed about their concepts of asthma etiology, asthma medications, and alternative therapies. Drawings were elicited from children to understand their beliefs about asthma. Nineteen children with 17 mothers from a variety of cultural backgrounds were interviewed. Among children, contagion was the primary EM for asthma etiology (53%). Twenty-five percent of children reported fear of dying from asthma, while fear of their child dying from asthma was reported by 76% of mothers. Mothers reported a variety of EMs, some culturally specific, but the majority reported biomedical concepts of etiology, pathophysiology, and triggers. Although 76% of mothers knew the names of more than one of their children's medications, 47% thought their child's medications all had similar functions. Thirty-five percent of families used herbal treatments and 35% incorporated religion into asthma treatment. Seventy-one percent of families had discontinued medications and 23% reported currently not giving anti-inflammatory medication. Reasons for discontinuing daily medications included fears of unknown side effects (53%), addiction (18%), tachyphylaxis (18%), and feeling that their child was being given too much medicine (23%). The traditional focus of asthma education is not sufficient to ensure adherence. Asthma education for children should address their views of etiology and fears about dying from asthma. Conversations with parents about their EMs and beliefs about medications and alternative therapies could assist in understanding and responding to parental concerns and choices about medications and help achieve better adherence.

The use of complementary therapies in inner-city asthmatic children

Use of complementary/alternative medicine (CAM) has been increasing, especially among patients with a chronic illness. Although asthma is the most common chronic illness affecting children in the United States, very little is known about the use of CAM in children with asthma. Our objective was to determine the prevalence and correlates of CAM use among inner-city children with asthma. A cross-sectional survey of parents of children with asthma attending an urban health center was performed. Parents were surveyed regarding CAM use over the past year, perceived efficacy of CAM, severity of child's asthma symptoms and demographic information. Differences in proportions were tested by chi-square or Fisher's exact test as appropriate. Three hundred ten parents participated, of whom 61% were Hispanic and 37% were African American. Parental mean age was 33 years and the mean age of the child was 7.2 years; 89% of parents had treated their child in the past year with some form of CAM. However, only 18% had informed a physician of doing so. The most common forms of CAM used were as follows: prayers (53%), rubs (53%), and massage (45%). Of those who used CAM, 59% perceived it to be at least as effective as pharmacotherapy, and 44% used CAM as first treatment of an asthma attack. Mild and moderate persistent asthmatics had significantly higher rates of CAM use than did mild intermittent and severe persistent asthmatics. We found a very high rate of CAM use among children with asthma in this inner-city population. Most importantly, a very high proportion of parents perceived the therapies to be effective, used them as first treatment of an acute exacerbation, and did not inform a physician of doing so. These findings have implications for the care of asthmatic children by pediatricians practicing in urban settings.

Ethnic specific recommendations in clinical practice guidelines: a first exploratory comparison between guidelines from the USA, Canada, the UK, and the Netherlands

OBJECTIVES

To investigate whether clinical practice guidelines in different countries take ethnic differences between patients into consideration and to assess the scientific foundation of such ethnic specific recommendations.

DESIGN

Analysis of the primary care sections of clinical practice guidelines.

SETTING

Primary care practice guidelines for type 2 diabetes mellitus, hypertension, and asthma developed in the USA, Canada, the UK, and the Netherlands.

MAIN OUTCOME MEASURES

Enumeration of the ethnic specific information and recommendations in the guidelines, and the scientific basis and strength of this evidence.

RESULTS

Different guidelines do address ethnic differences between patients, but to a varying extent. The USA guidelines contained the most ethnic specific statements and the Dutch guidelines the least. Most ethnic specific statements were backed by scientific evidence, usually arising from descriptive studies or narrative reviews.

CONCLUSION

The attention given to ethnic differences between patients in clinical guidelines varies between countries. Guideline developers should be aware of the potential problems of ignoring differences in ethnicity.

Use of complementary and alternative medicine among children recently diagnosed with autistic spectrum disorder

This study examined the prevalence and correlates of use of different types of complementary and alternative medicine (CAM) among a sample of children with suspected or recently diagnosed autism. The authors' review of 284 charts of children seen at the Regional Autism Center of The Children's Hospital of Philadelphia, Pennsylvania, found that more than 30% of children were using some CAM, and that 9% were using potentially harmful CAM. Having an additional diagnosis was protective against CAM use and being Latino was associated with CAM use. Having seen a prior provider regarding the child's health condition was predictive of potentially harmful CAM use. Further research is required on cultural differences in treatment decisions about CAM, as well as the reasons for the association between the use of prior providers and CAM. The high prevalence of CAM use among a recently diagnosed sample indicates that clinicians should discuss CAM early in the assessment process.

Cultural aspects in the treatment of patients with skin disease

As the cultural distance between patient and physician widens, so does miscommunication. Negotiation between the belief systems of the physician and the patient may create a therapeutic environment of mutual trust and respect that increases the possibility of successful clinical outcomes.

Complementary and alternative medicine in children with asthma

BACKGROUND

The popularity of complementary and alternative medicine (CAM), particularly for chronic conditions such as asthma, is growing rapidly, but little is known about its use in asthmatic children.

OBJECTIVE

To evaluate the extent, characteristics, and possible predictors of CAM use in a group of Turkish children with asthma.

METHODS

The parents of asthmatic children were invited to participate in a questionnaire-based survey of 13 worldwide and 5 local methods of CAM. Current asthma treatment, asthma exacerbations, emergency admittances and hospitalizations due to exacerbations, and parental education levels were investigated as predictors that influenced the use of CAM.

RESULTS

Of the 304 asthmatic children (mean +/- SEM age, 10.5 +/- 0.2 years; range, 1-16 years), 49% (n = 150) had used some form of CAM previously, and 38% had used CAM within the previous year. The most popular forms of CAM were quail eggs (79%), herbal medicine (31%), Turkish wild honey (26%), speleotherapy (5%), and royal jelly (5%). The respondents learned about CAM through friends (61%), relatives (25%), the media (9%), and physicians (6%). Age, sex, and mother's and father's education levels were insignificant between the groups that used and did not use CAM (P = 0.40, P = 0.18, P = 0.15, and P = 0.09, respectively). The use of regular asthma treatment, the use of inhaled corticosteroids, asthma exacerbations, emergency admittances, and treatment score were significantly high in the CAM group (P = 0.006, P = 0.03, P = 0.008, P = 0.02, and P = 0.02, respectively). A significantly high percentage of respondents in the CAM group had considered using CAM for their child's asthma in the future (P = 0.001).

CONCLUSIONS

Asthmatic children in whom the disease is not well controlled are more likely to use CAM as complementary therapy.

The Tuskegee Legacy Project: history, preliminary scientific findings, and unanticipated societal benefits

This article is intended to provide a relatively complete picture of how a pilot study--conceived and initiated within an NIDCR-funded RRCMOH--matured into a solid line of investigation within that center and "with legs" into a fully funded study within the next generation of NIDCR centers on this topic of health disparities, the Centers for Research to Reduce Oral Health Disparities. It highlights the natural opportunity that these centers provide for multicenter. cross-disciplinary research and for research career pipelining for college and dental school students; with a focus, in this case, on minority students. Futhermore, this series of events demonstrates the rich potential that these types of research centers have to contribute in ways that far exceed the scientific outcomes that form their core. In this instance, the NMOHRC played a central--and critical, if unanticipated--role in contributing to two events of national significance, namely the presidential apology to the African American community for the research abuses of the USPHS--Tuskegee syphilis study and the establishment of the National Center for Bioethics in Research and Health Care at Tuskegee University. Research Centers supported by the NIH are fully intended to create a vortex of scientific activity that goes well beyond the direct scientific aims of the studies initially funded within those centers. The maxim is that the whole should be greater than the sum of its initial constituent studies or parts. We believe that NMOHRC did indeed achieve that maxim--even extending "the whole" to include broad societal impact. well beyond the scope of important, but mere, scientific outcomes--all within the concept and appropriate functions of a scientific NIH-funded research center.

Variation in asthma beliefs and practices among mainland Puerto Ricans, Mexican-Americans, Mexicans, and Guatemalans

This study reports on community surveys of 160 representative Latino adults in Hartford, CT, Edinburg, TX, Guadalajara, Mexico; and in rural Guatemala. A 142-item questionnaire covered asthma beliefs and practices (e.g., causes, symptoms, and treatments). The cultural consensus model was used to analyze the agreement among respondents within each sample and to describe beliefs. Beliefs were then compared across the four samples. Analysis of the questionnaire data shows that there was overall consistency or consensus regarding beliefs and practices among individuals at each site (intraculturally) and to a lesser extent across respondents of all four different Latino cultural groups (i.e., interculturally). This pattern of response is indicative of a shared belief system among the four groups with regard to asthma. Within this shared belief system though, there is systematic variation between groups in causes, symptoms, and treatments for asthma. The most widely recognized and shared beliefs concerned causes of asthma. Notable differences were present between samples in terms of differences in beliefs about symptoms and treatments. The biomedical model is shown to be a part of the explanatory model at all sites; in addition to the biomedical model, ethnocultural beliefs such as the humoral ("hot/cold") aspects and the importance of balance are also evident. The Connecticut Puerto Ricans had a greater degree of shared beliefs about asthma than did the other three samples (p < 0.00005). It was concluded that the four Latino groups studied share an overall belief system regarding asthma, including many aspects of the biomedical model of asthma. In addition, traditional Latino ethnomedical beliefs are present, especially concerning the importance of balance in health and illness. Many beliefs and practices are site-specific, and caution should be used when using inclusive terms such as "Hispanic" or "Latino," since there is variation as well as commonality among different ethnic groups with regard to health beliefs and practices.

Reducing disparities in asthma care: priorities for research--National Heart, Lung, and Blood Institute workshop report

Minority groups with diverse racial and ethnic heritages and persons living in poverty are much more likely to die of asthma and to require emergency care for exacerbations of asthma than white persons not living in poverty. The National Heart, Lung, and Blood Institute convened a multidisciplinary group of expert scientists and clinicians to review current research aimed at understanding risk factors for these disparities in asthma health outcomes, to describe key barriers to improving asthma outcomes, and to establish priorities for future research. Education programs for asthma and other chronic diseases were reviewed. Successful elements of clinic and community-based programs were identified. Factors potentially involved in producing disparities include gene-environment interaction, psychologic and social factors, and socioeconomic status. Stress potentially contributes to asthma morbidity at both the individual and community level. Recommendations are made to stimulate research to understand risk factors for disparities and their mechanisms (e.g., gene-by-environment interactions and the role of stress), to define appropriate research designs and methods for evaluating behavioral and community interventions, and to examine how differential access to care contributes to morbidity. Research is encouraged to identify strategies that improve cultural adaptation and adoption of proven programs in a variety of populations.

Complementary medicine use in children and young adults with inflammatory bowel disease

OBJECTIVES

We examined the use of complementary alternative medicine (CAM) in children and young adults with inflammatory bowel disease.

METHODS

After validation of a questionnaire and completion of a pilot survey, children and young adults with inflammatory bowel disease were enrolled in three centers of pediatric gastroenterology (Boston, Detroit, and London).

RESULTS

Two hundred eight questionnaires were completed in total (Boston, 120; Detroit, 37; London, 51). Ages ranged from 3.8 to 23.0 yr, 58% were male, 57% had Crohn's disease, and 35% had ulcerative colitis. The frequency of CAM use was 41%. The most common CAMs were megavitamin therapy (19%), dietary supplements (17%), and herbal medicine (14%). Parental CAM use and the number of adverse effects from conventional medicines were predictors of CAM use (odds ratio = 1.9, 95% CI = 1.2-3.1, p = 0.02; odds ratio = 1.3, 95% CI = 1.2-1.5, p < 0.001, respectively). The most important reasons respondents gave for using CAM were side effects from prescribed medicines, prescribed medicines not working as well as they had hoped, and hoping for a cure. Fifty-nine percent of respondents not taking CAM were interested in learning more about it.

CONCLUSIONS

In our survey over 40% of children with chronic inflammatory bowel disease used complementary medicine in addition to conventional therapies. Parental CAM use and number of adverse effects from conventional therapies were the only independent predictors of CAM use. Some complementary therapies have potential for adverse effects and for drug interactions with conventional treatments. Physicians should take a thorough history of CAM use in children with chronic inflammatory bowel disease.
