Ischaemic heart disease and Australian immigrants: the influence of birthplace and language skills on treatment and use of health services

Admission rates for ischaemic heart disease (IHD), and the use of invasive cardiovascular procedures, separation mode and length of stay (LOS) were compared between Australians from non-English speaking background (NESB; n=8627) and English speaking background (ESB; n=13162) aged 20 years and over admitted to Victorian urban public hospitals. The study covered the period from 1993 to 1998. It was found that, compared with their ESB counterparts, the incidence of admission for acute myocardial infarction was significantly higher for NESB men and women before and after controlling for confounding factors. The age-adjusted ratios for NESB women compared with their ESB counterparts ranged from 1.23 to 1.89 for cardiac catheterisation, from 0.23 to 0.27 for percutaneous transluminal coronary angioplasty (PTCA), and from 1.04 to 1.80 for coronary artery bypass grafting (CABG).
Procedure rates were comparable in men for cardiac catheterisation and CABG but higher for PTA rates in NESB men (OR: 1.29, 95%CI: 1.11-1.50) than their ESB counterparts. Both NESB men (β=0.04, 95%CI: 0.01-0.07) and women (β=0.03, 95%CI: 0.02-0.08) experienced significantly longer hospital stays than their ESB counterparts. These findings indicate there may be systematic differences in patients’ treatment and service utilisation in Victorian public hospitals. The extent to which physicians’ bias and
patients’ choice could explain these differences requires further investigation.

A culturally appropriate diet and lifestyle intervention can successfully treat the components of metabolic syndrome in female Pakistani immigrants residing in Melbourne, Australia

This study was designed to test the effectiveness of a culturally appropriate diet and lifestyle intervention to treat metabolic syndrome in female Pakistani immigrants residing in Melbourne, Australia. Forty Pakistani women with metabolic syndrome (aged 20-50 years) completed a 12-week culturally appropriate diet and exercise program. Results indicate that, before intervention, participants were sedentary, taking 4000 ± 22.6 steps per day, and had an obese-classified body mass index (BMI) of 29.2 ± 0.46 kg/m2 (BMI was categorized in accordance with guidelines specifically designed for Asians) and high waist circumference of 132 ± 25.95 cm. Participants were hypertensive (systolic, 135 ± 1.3 mm Hg; diastolic, 86 ± 0.68 mm Hg), were dyslipidemic (total cholesterol, 6.8 ± 0.15 mmol/L; triglycerides, 2.9 ± 0.09 mmol/L), and had elevated blood glucose (6.4 ± 0.33 mmol/L) and fasting blood insulin (45 ± 6.3 μU/mL) levels. After the 12-week culturally appropriate intervention, activity increased (8600 ± 596.7 steps per day, P < .05); and BMI (27.8 ± 0.45 kg/m2), blood pressure (systolic, 125 ± 1.4 mm Hg; diastolic, 80 ± 0.6 mm Hg), cholesterol (5.5 ± 0.1 mmol/L), blood glucose (5.9 ± 0.33 mmol/L), and blood insulin (24.14 ± 1.8 μU/mL) levels were all significantly reduced (P < .05). This study revealed that the Pakistani female migrants who had metabolic syndrome and its components can successfully be treated via a culturally appropriate diet and lifestyle intervention. The success of the current program raises the possibility that other high-risk ethnic groups can also be treated with a culturally appropriate program.

Over and undernutrition in the children of Australian immigrants : assessing the influence of birthplace of primary carer and english language use at home on the nutritional status of 4-5-year-olds

Objective. To document the relationship between childhood nutrition status and ethnicity (defined as the birthplace of primary carer and English language use at home) using a nationally representative sample of 4- to 5-year-old children. Design and participants. Cross-sectional population survey of 4 983 4- to 5-year-old children (2 537 boys and 2 446 girls) as part of Wave 1 (2004) of the Longitudinal Study of Australian Children. Main outcome measures. Overweight/obesity and thinness using the newly published body mass index cut-off points of Cole (2007). Results. In total, 20.6% (95%CI 19.5, 21.7) of children aged 4 to 5 years were estimated to be overweight or obese, while 1.0% (95%CI 0.8, 1.3) was thin. Unadjusted analyses showed a significant relationship between childhood overweight/obesity and primary carer's country of birth (χ2=15.9, p<0.01), but the significance became minimal after adjusting for socio-economic and demographic factors. The adjusted model suggests that boys of primary carer's born in Europe (excluding UK and Ireland) were less likely to be overweight/obese than boys whose primary carers were born in Australia, but the overall effect size was negligible. No difference was found for girls. In addition, boys who mainly spoke English at home were less likely to be overweight/obese (OR=0.49; 95%CI 0.27, 0.88; p=0.017) and thin (OR=0.27; 95%CI 0.12, 0.62; p=0.002) than boys who spoke a language other than English at home. No difference was found for girls. Conclusions. There is a relationship between main language spoken at home and nutritional status in 4-5-year-old boys but not girls. The use of English language at home may be a protective factor for normal weight in young boys. After adjustment for socio-economic and demographics characteristics, there was a negligible relationship between overweight/obesity in children and their primary carer's country of birth.

Effectiveness of prevention programmes for obesity and chronic diseases amongst immigrants to developed countries - a systematic review

Objective: To determine whether interventions tailored specifically to  particular immigrant groups from developing to developed countries  decrease the risk of obesity and obesity-related diseases.

Design: Databases searched were MEDLINE (1966–September 2008), CINAHL (1982–September 2008) and PsychINFO (1960–September 2008), as well as Sociological Abstracts, PsychARTICLES, Science Direct, Web of Knowledge and Google Scholar. Studies were included if they were randomised control trials, ‘quasi-randomised’ trials or controlled before-and-after studies. Due to the heterogeneity of study characteristics only a narrative synthesis was undertaken, describing the target population, type and reported impact of the intervention and the effect size.

Results: Thirteen studies met the inclusion criteria. Ten out of thirteen (77 %) studies focused on diabetes, seven (70 %) of which showed significant improvement in addressing diabetes-related behaviours and glycaemic control. The effect on diabetes was greater in culturally tailored and facilitated interventions that encompassed multiple strategies. Six out of the thirteen studies (46 %) incorporated anthropometric data, physical activity and healthy eating as ways to minimise weight gain and diabetes-related outcomes. Of the six interventions that included anthropometric data, only two (33 %) reported improvement in BMI Z-scores, total skinfold thickness or proportion of body fat. Only one in three (33 %) of the studies that included cardiovascular risk factors reported improvement in diastolic blood pressure after adjusting for baseline characteristics. All studies, except four, were of poor quality (small sample size, poor internal consistency of scale, not controlling for baseline characteristics).

Conclusions: Due to the small number of studies included in the present review, the findings that culturally tailored and facilitated interventions produce better outcomes than generalised interventions, and that intervention content is more important than the duration or venue, require further investigation.

Undiagnosed and potentially lethal parasite infections among immigrants and refugees in Australia

Background: Intestinal parasite infections are a major cause of ill health in many resource-poor countries. This study compares the types and rates of these infections and their risk factors in recently arrived and long-term immigrants in Australia.

Method: Cross-sectional surveys of 127 East African and 234 Cambodian immigrants and refugees were undertaken in 2000 and 2002, respectively, to assess the burden of intestinal parasites and collect demographic information. Serum samples were assessed for eosinophilia and Strongyloides stercoralis and Schistosoma antibodies, and feces examined for ova, cysts, and parasites.

Results: Intestinal parasites were identified in 77/117 fecal samples from East African and in 25/204 samples collected from Cambodian participants. Eleven percent (14/124) of East Africans and 42% (97/230) of Cambodians had positive or equivocal serology for S stercoralis. Schistosoma serology was positive or equivocal in 15% (19/124) of East African participants.

Conclusion: Potentially serious intestinal parasite infections are common among recent and longer term immigrants despite multiple visits to health care providers. Immigrants and refugees from high-risk countries would benefit from comprehensive health checks soon after resettlement.

Bauman, strangerhood and attitudes towards immigrants among the Australian population

Through an investigation of the idea of the stranger, this article seeks to blend theory with empirical research. It does this in three ways. First, it engages with a social theory of the stranger articulated in the work of Zygmunt Bauman. Second, it examines data from the Australian Election Study surveys between 1996 and 2007 in order to explore attitudinal changes towards groups of immigrants. The findings from this survey suggests that attitudes towards immigrants in general have fluctuated in Australia, despite the negative effects of economic globalization, the growth in neoliberal economic reforms and terrorist attacks in the West. Third, drawing on Bauman's theory of the stranger we provide an interpretation of these fluctuating attitudes through the idea of the hybrid stranger. Finally, we argue that a more nuanced understanding of these attitudes towards immigrants in Australia is possible when a theory of the stranger is informed by a discussion on the constitution of host self, the influence of the media, the role of government policy, and the impact of class and geography.

Problems of psychological and sociocultural adaptation among Russian speaking immigrants in New Zealand

The problems immigrants experience during the process of their psychological and sociocultural adaptation to the host culture have far-reaching effects in terms of mental health, employment and lost benefits for the whole society. General models of the acculturation process (Ward 1996) and acculturation strategies (Berry 2001) provide a basis for the analysis of those problems. The current study employed a qualitative, case-oriented design, based on the grounded theory method to analyse interviews with six Russian-speaking immigrants in New Zealand. The purpose of the study was to investigate, from a psychological perspective, the problems in adaptation as a result of migration and resettlement, and the factors that influence this process. Two distinct patterns were revealed, linked to acculturation strategies of integration and separation. All the participants experienced high levels of psychological distress in the initial stage of their resettlement, but those who later chose the integration strategy of acculturation were more successful and satisfied with their adaptation than those who chose the strategy of separation. Factors contributing to the process of adaptation were migration motivation, proportion of perceived gains and losses, and cultural identity. This study has implications for social policies in the areas of employment, education and mental health.

Resisting immigrant myths : everyday consumer practices of Asian immigrants in America

Projective, depth interviews with U.S. Asian immigrants revealed their ambivalence toward the U.S. commercial sector’s colonial-era representations of Asian people. These commercial representations provide polarized depictions of Asian immigrants as either threatening aliens or as model citizens. These portrayals reflect “racialized otherness,” or racial stereotyping that represent Asian immigrants as inferior. Our findings indicate that Chinese immigrants strategically use everyday consumption related to foodways to resist the reverberation of American immigrant myths. In some instances, immigrants’ consumption practices instantiate a regional Asian identity. In other instances, however, immigrants’ consumption practices reflect a separation from the past and an acceptance of a new although not exclusively American way of life. Notwithstanding immigrant consumers’ resistance practices, the findings call for future research into immigrant consumers’ reactions to visual representations of race, ethnicity, and gender.

Stigma toward mental illness : a cross-cultural comparison of Taiwanese, Chinese immigrants to Australia and Anglo-Australians

This study investigated the relationship between culture and attitudes toward mental illness. In total, 196 men and 347 women were recruited from Australia and Taiwan. All participants completed a questionnaire assessing their attitudes toward mental illness. Australian-born Chinese and Chinese immigrants to Australia also completed a questionnaire assessing cultural values. Chinese immigrants to Australia and Taiwanese held more stigmatizing attitudes than Australian-born Chinese and Anglo-Australians. Australian-born Chinese adopted Australian cultural practices more than Chinese immigrants, but these groups did not differ in terms of adherence to Chinese cultural practices. The adoption of Australian cultural practices was significantly associated with lower stigmatizing attitudes. These findings reveal the influence of culture and acculturation processes on stigmatizing attitudes toward the mentally ill.

Experiences of migration and the determinants of obesity among recent Iranian immigrants in Victoria, Australia

Objectives. There is evidence to suggest that immigrant groups from low- or medium-human development index countries show a significant adoption of obesogenic behaviors and experience weight gain following migration to Australia. The objective of this study is to understand the changes that Iranian immigrants experience in relation to the determinants of obesity after migration to Victoria, Australia.

Design. We conducted five focus group discussions with 33 recent Iranian immigrants. This study took an interpretive qualitative approach to data analysis using the constant comparative method.

Results. Participants discussed individual level acculturation (e.g., in diet, body size, attitudes), as well as environmental level changes (e.g., physical/structural and sociocultural) that occurred after immigration. Stress during the initial immigration transition, which affected diet and physical activity habits, was a common experience among participants. Gender and the effect of political/religious changes were also important factors. Participants' discourse largely focused on their ability and willingness to adopt positive health behaviors after migration.

Conclusion. This study provides insight into the effect of migration on the determinants of obesity among Iranian immigrants in Victoria, Australia, and offers a contrast with the existing evidence by considering the experience of a group that is generally well educated, often emigrates for reasons related to personal freedom as opposed to material deprivation, and has rates of obesity similar to high-income countries.
