Asthma in a Vietnamese refugee population

Prevalence of Complementary and Alternative Medicine Usage in Vietnamese American Asthmatic Children

This study examined the frequency and type of complementary and alternative medicine (CAM) therapy, as well as characteristics associated with CAM usage. A survey about parental preferences and beliefs regarding CAM usage was distributed to 5 schools with predominantly low socioeconomic Vietnamese children. For the 360 Vietnamese children previously diagnosed with asthma whose families responded, most preferred conventional therapy as prescribed by the physician. The prevalence of CAM usage was 38.1%. Common CAM therapies were steam inhalation, creams/topical oils, foods, prayer, oil inhalation, massage, herbal medication, coining, and cupping. Significant predictors of CAM usage were older age (11-12 years) (P = .038), English language of survey response (P = .001), environmental tobacco smoke exposure (P = .001), fear of long-term medication usage, and perception of asthma as a condition related to genetics (P = .023). These findings suggest that assessing CAM therapy will provide a more holistic approach to asthma therapy.

The prevalence of asthma risk and contributing factors in underserved Vietnamese children in Orange County, CA

OBJECTIVES

Vietnamese constitutes one of the fastest growing minority groups in America, with the largest concentration in Orange County (OC), CA. Yet, there are limited data on the prevalence of asthma in Vietnamese children. Our study evaluated the risk of asthma and key contributing factors among these children living in OC, CA.

METHOD

Five elementary schools in OC that were predominantly Vietnamese with low socioeconomic status were selected for participation. Validated surveys were sent to parents of all students ages 3-12 in these schools with materials available in English, Vietnamese and Spanish. Surveys included questions to identify the risk of asthma and related key factors. Surveys were completed by parents and returned to schools.

RESULTS

There were 1530 participants eligible for analysis. Asthma risk was 30.4%, and of these, 22.6% had no prior diagnosis. Contributing factors to identification of those at risk were male gender (p < 0.001), preferred use of the Vietnamese language (p = 0.004), longer duration in the United States (p = 0.019), and smoker in the household (p = 0.015).

CONCLUSIONS

The prevalence of asthma risk in our community of low socioeconomic status Vietnamese children was found to be higher than commonly appreciated. Furthermore, a considerable number of these children had not been previously diagnosed. Given the limited information in this population, our current findings of asthma risk and key contributing factors could affect health care policies that allow appropriate funding for programs dedicated to asthma care in this and other growing population.

Adaptation of an evidence-based intervention to promote colorectal cancer screening: a quasi-experimental study

Background

To accelerate the translation of research findings into practice for underserved populations, we investigated the adaptation of an evidence-based intervention (EBI), designed to increase colorectal cancer (CRC) screening in one limited English-proficient (LEP) population (Chinese), for another LEP group (Vietnamese) with overlapping cultural and health beliefs.

Methods

Guided by Diffusion of Innovations Theory, we adapted the EBI to achieve greater reach. Core elements of the adapted intervention included: small media (a DVD and pamphlet) translated into Vietnamese from Chinese; medical assistants distributing the small media instead of a health educator; and presentations on CRC screening to the medical assistants. A quasi-experimental study examined CRC screening adherence among eligible Vietnamese patients at the intervention and control clinics, before and after the 24-month intervention. The proportion of the adherence was assessed using generalized linear mixed models that account for clustering under primary care providers and also within-patient correlation between baseline and follow up.

Results

Our study included two cross-sectional samples: 1,016 at baseline (604 in the intervention clinic and 412 in the control clinic) and 1,260 post-intervention (746 in the intervention and 514 in the control clinic), including appreciable overlaps between the two time points. Pre-post change in CRC screening over time, expressed as an odds ratio (OR) of CRC screening adherence by time, showed a marginally-significant greater increase in CRC screening adherence at the intervention clinic compared to the control clinic (the ratio of the two ORs = 1.42; 95% CI 0.95, 2.15). In the sample of patients who were non-adherent to CRC screening at baseline, compared to the control clinic, the intervention clinic had marginally-significant greater increase in FOBT (adjusted OR = 1.77; 95% CI 0.98, 3.18) and a statistically-significantly greater increase in CRC screening adherence (adjusted OR = 1.70; 95% CI 1.05, 2.75).

Conclusions

Theoretically guided adaptations of EBIs may accelerate the translation of research into practice. Adaptation has the potential to mitigate health disparities for hard-to-reach populations in a timely manner.

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.

Comparison of health-seeking behaviour between poor and better-off people after health sector reform in Cambodia

This study compared health-seeking behaviour between poor and better-off people after health sector reform in Cambodia. The survey was conducted in the Prek Dach Health Centre coverage area, which is located in South-east Cambodia. The study population consisted of 257 housewives of reproductive age, selected at random. Data were collected through household surveys with a structured questionnaire. Data collected included socio-demographic information on the housewives, as well as episodes of illness of family members within 30 days prior to the survey. Two indicators, the floor area of living space and a rating scale on asset ownership, were used to identify poor and very poor people. When a family member became ill, subjects most often used home remedies as a first step, followed by self-medication. Subsequently, people used self-medication or the private health sector. Very poor people used the health centre more often than better-off people as a first step. For the second step, use of the health centre was also high among the poor compared with better-off people, although the difference was not statistically significant. Keeping the treatment fees low and abolishing informal fees maintained the affordability of health-centre services for the poor. However, this benefit diminished quickly with distance from the health centre. The significant difference between poor and better-off people disappeared for villages situated more than 2 km from the health centre. Thus, the health centre in the studied area was shown to be effective in providing primary health care to the economically disadvantaged, but only within a limited geographic area.

Asthma prevalence among inner-city Asian American schoolchildren

OBJECTIVE

Though asthma has been studied in many inner-city populations in the United States, there have been no studies specifically on Asian American immigrants. The authors conducted a cross-sectional survey of the prevalence of asthma among schoolchildren at the Josiah Quincy Elementary School, located in Boston Chinatown. Roughly 62% of the students in the school are Asian American.

METHODS

The authors utilized the Brief Asthma Pediatric Screen (BAPS), a five-question instrument that was validated through the Chicago public schools. The survey was administered to kindergarten through fifth grade students.

RESULTS

Of the 606 respondents (69.9% of the students), 16% had previously diagnosed asthma and 3% had possible undiagnosed asthma. Asthma was more prevalent in boys than in girls (relative risk [RR] 1.75; 95% confidence interval [CI] 1.20, 2.56). In addition, the respondents who lived in Chinatown were less likely to have been diagnosed with asthma (RR 0.59; 95% CI 0.39, 0.90), as were those with Asian surnames (RR 0.65; 95% CI 0.44, 0.97).

CONCLUSION

Although this study was preliminary, our results suggest that asthma rates are substantial among inner-city Asian immigrant children, but possibly lower than for other inner-city children.

Natural history of chronic asthma and its long-term effects on pulmonary function

Although asthma is a disease that has intrigued physicians since antiquity, its natural history has been incompletely determined. It has long been held that the presence of asthma, per se, does not carry with it any long-term deterioration in lung function, but recently this view has been challenged, and it has become fashionable to define asthma as being only partially reversible. At present, there are limited data to support such a view. All of the available information indicates that the vast majority of patients do not experience the development of a progressive decline in pulmonary mechanics or appear to be at risk for a diminution in life expectancy.

Adverse asthma outcomes among children hospitalized with asthma in California

OBJECTIVE

To use administrative data to determine whether adverse asthma outcomes for pediatric asthma hospitalizations are related to specific clinical and nonclinical patient characteristics.

DESIGN

Cross-sectional study.

SETTING

All pediatric (0 to 17 years of age) asthma-related hospital discharges, 1986 to 1993, in California.

PATIENTS

A total of 113 974 eligible patients with asthma-related discharges.

MAIN OUTCOME MEASURE

Adverse asthma outcomes (intubation, cardiopulmonary arrest, and death).

RESULTS

Adverse asthma outcomes occurred in 0.48% of subjects. The frequency of adverse asthma outcomes increased during the 1990s compared with 1986. After controlling for differences in gender, age, specific comorbid conditions, year, race, and insurance type, adverse asthma outcomes were more likely to occur in the 5- to 11-year-old group (odds ratio [OR]: 1.39; 95% confidence interval [CI]: 1.13-1.69) and in the 12- to 17-year-old group (OR: 4.48; CI: 3.20-6.21) compared with those children in the 0 to 4-year-old age group. Asian Pacific-American children were more likely (OR: 1.59; CI: 1.24-2.59) than were white children to experience an adverse asthma outcome. Children who had a secondary diagnoses of pneumonia (OR: 1.54; CI: 1. 19-2.00) also were more likely to experience an adverse asthma outcome. The odds of an adverse outcome increased progressively after 1986, becoming significant after 1989. Gender and insurance type were not associated with increased odds of experiencing an adverse asthma outcome.

CONCLUSIONS

Adverse asthma outcomes among hospitalized children are increasing in the 1990s and are associated with specific clinical and nonclinical patient characteristics.
