Differences in cardiometabolic risk markers among ethnic groups in Queensland, Australia

Modifiable Risk Factors for Dementia Among Migrants, Refugees and Asylum Seekers in Australia: A Systematic Review

While the prevalence of non-communicable disease risk factors is understood to be higher among migrants than for people born in host nations, little is known about the dementia risk profile of migrants, refugees and asylum seekers. This systematic review examines published literature to understand what is currently reported about 12 identified modifiable risk factors for dementia among migrants, refugees, and asylum seekers residing in Australia. Three literature databases (PubMed/CINAHL/MEDLINE) were systematically searched to find articles reporting excessive alcohol consumption, traumatic brain injury, air pollution, lack of education, hypertension, hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, and limited social contact in Australia's migrant, refugee and asylum seeker population samples. Papers were systematically reviewed following PRISMA guidelines. A total of 763 studies were found, of which 676 articles were excluded, and 79 articles remained. Despite wide variability in study design, size and purpose, the prevalence and correlates of modifiable risk factors of dementia appears markedly different among the studied samples. Compared with Australian-born participants, migrant samples had a higher prevalence of depression, social isolation, physical inactivity and diabetes mellitus. Insufficient information or conflicting evidence prevented inference about prevalence and correlates for the remaining dementia risk factors. A better understanding of the prevalence and correlates of modifiable dementia risk factors is needed in Australia's migrant, refugee and asylum seeker populations. This information, together with a deeper understanding of the contextual and cultural contributing factors affecting people who arrive in Australia through differing pathways is needed before preventive interventions can be realistically targeted and sensitively implemented.

The Evolution of Urban Australian Meat-Eating Practices

This qualitative study used social practice theory to explore how meat-eating practices are changing in contemporary urban Australia, drawing on a sample of Sydney residents aged 23–45 years. The research used an iterative study design and an inductive analysis approach. Semi-structured face-to-face in-depth interviews were the main mode of data collection, supplemented by observations in places such as markets and local neighborhoods. Research participants explained that the role of meat in their diet has changed in response to shifting conventions and social infrastructures. They have reduced consumption of red meat in favor of meats considered healthier or more ethical. Key factors driving the change include exposure to alternative eating practices brought about through changes in political policy and the advent of globalization. Changing discourses of masculinity and the move toward embracing more fluid representations of gender have, in turn, changed meanings in relation to the meat-eating man and a meat-heavy diet. Rising environmental and health consciousness, and concerns for animal welfare have also contributed to dietary changes. While several participants claimed to have increased their consumption of plant-based foods, meat still continues to maintain a significant presence within their diets. Many participants expressed interest in cutting back further on meat consumption and adopting more plant-based foods but they also identified several challenges—e.g., limited access to plant-based ingredients and recipes, negative meanings associated with vegetarian and vegan diets, and a lack of competence in relation to preparing and consuming appetizing meals using plant-based foods.

A Longitudinal Assessment of Risk Factors and Chronic Diseases among Immigrant and Non-Immigrant Adults in Australia

This study aimed to investigate the prevalence and trajectories of chronic diseases and risk behaviors in immigrants from high-income countries (HIC), low–middle-income countries (LMIC), to Australian-born people. Data were used from five waves of the HABITAT (2007–2016) study—11,035 adults living in Brisbane, Australia. Chronic diseases included cancer, diabetes mellitus, coronary heart disease, and chronic obstructive pulmonary disease (COPD). Risk factors assessed were body mass index (BMI), insufficient physical activity, and cigarette smoking. Diabetes mellitus increased in all groups, with the highest increase of 33% in LMIC immigrants. The prevalence of cancers increased 19.6% in the Australian-born, 16.6% in HIC immigrants, and 5.1% in LMIC immigrants. The prevalence of asthma increased in HIC immigrants while decreased in the other two groups. Poisson regression showed that LMIC immigrants had 1.12 times higher rates of insufficient physical activity, 0.75 times lower rates of smoking, and 0.77 times lower rates of being overweight than the Australian-born population. HIC immigrants had 0.96 times lower rates of insufficient physical activity and 0.93 times lower rates of overweight than Australian-born. The findings of this study can inform better strategies to reduce health disparities by targeting high-risk cohorts.

Definitions of Culturally and Linguistically Diverse (CALD): A Literature Review of Epidemiological Research in Australia

Objective: To identify how Culturally and Linguistically Diverse (CALD) communities are defined in epidemiological research in Australia and provide a definition of CALD status that aids the consistency and interpretability of epidemiological studies. Methods: Peer-reviewed literature from January 2015 to May 2020 was searched via four databases (Ovid Medline combined with PubMed, Embase, Emcare, and CINAHL) to identify quantitative studies of CALD people in Australia. Results: A total of 108 studies met the criteria for inclusion in the review. Country of birth was the most commonly used CALD definition (n = 33, 30.6%), with combinations of two or more components also frequently used (n = 31, 28.7%). No studies used all the components suggested as core to defining CALD status. including country of birth, languages other than English spoken at home, English proficiency, and indigenous status. Conclusions: There was considerable inconsistency in how CALD status was defined. The review suggests that CALD status would best be defined as people born in non-English speaking countries, and/or who do not speak English at home. Additionally, indigenous peoples should be considered separately. This recommended definition will support the better identification of potential health disparity and needs in CALD and indigenous communities.

Eating and physical activity behaviours among ethnic groups in Queensland, Australia

OBJECTIVE

To examine differences in eating and physical activity behaviours among ethnic groups in Queensland, Australia, and differences in those behaviours due to the duration of residency in Australia.

DESIGN

Cross-sectional study using baseline data collected for the Living Well Multicultural-Lifestyle Modification Program between October 2014 and June 2017.

SETTING

Culturally and linguistically diverse communities (CALD), including Afghani, Somali, Burmese, Pacific and South Sea Islander, Sri Lankan, Sudanese and Vietnamese, living in Queensland, Australia.

PARTICIPANTS

People were recruited if they were ≥18 years old and living in the targeted CALD communities.

RESULTS

Burmese/Vietnamese, on average, had better eating scores in line with Australian dietary guidelines, compared with Afghani/Arabic-speaking (difference = 2·05 points, 95 % CI 1·39, 2·72), Somali/Sudanese (difference = 1·53 points, 95 % CI 0·79, 2·28) and Pacific Islander (difference = 1·46 points, 95 % CI 0·79, 2·13). Association between ethnicity and meeting the physical activity guideline was not significant. Those who stayed in Australia longer than a year were less likely to meet the physical activity guideline than those staying <1 year (OR = 0·51, 95 % CI 0·31, 0·84). There was no significant association between duration of residency in Australia and eating scores.

CONCLUSIONS

Eating behaviours were significantly different among the ethnic groups in Queensland with Burmese/Vietnamese and Sri Lankan/Bhutanese having the healthiest diets. All ethnic groups were less likely to meet the physical activity guideline compared with the general Australian population. People with duration of residency of at least 1 year in Australia were less likely to meet the physical activity guideline compared with those who had shorter stays.

The effectiveness of living well multicultural-lifestyle management program among ethnic populations in Queensland, Australia

ISSUE

Some migrant groups have higher risks of deaths and chronic diseases due to barriers associated with socioeconomic disadvantage, social isolation, racism, language, poor access to health services and low levels of health literacy. However, few culturally tailored interventions have targeted ethnic groups in Australia. This study evaluated the effectiveness of the Living Well Multicultural-Lifestyle Management Program (LWM-LMP) in Queensland, Australia.

METHODS

The LWM-LMP was originally co-designed with the targeted communities. Participants aged ≥18 years were eligible to participate without a fee. The evaluation was a quasi-experimental design without a control group, with data collected at baseline, the end of the programme and after-programme follow-up at week 14. The programme lasted 8 weeks with one group-based session of 120 minutes delivered each week in local community venues. Each session also included time to undertake physical activity (PA). Eating and PA behaviours were self-reported. Weight, height, waist circumference and blood pressure were measured using standard protocols.

RESULTS

Participants were more likely to consume ≥2 servings of fruit/day, five servings of vegetable/day, low-fat milk, processed meat, fast food, hot chips/fries, salty snacks, sweet snacks, sweet beverages less than once per week and meet the PA recommendation of ≥150 minutes/wk (P < .001) at week 8. Weight, BMI, waist circumference, waist-to-height ratio and blood pressure were also improved at week 8. Many of the changes were sustained at week 14.

CONCLUSIONS

The LWM-LMP was effective in improving participants' lifestyle behaviours and cardiometabolic indicators.

SO WHAT

Engaging targeted communities in designing interventions focussed on healthy personal behaviours helps with delivery and implementation. Behavioural interventions should be culturally tailored to increase their effectiveness.

Exploring the Health Care Challenges and Health Care Needs of Arabic-Speaking Immigrants with Cardiovascular Disease in Australia

The Arabic-speaking immigrant group, which makes up the fourth largest language group in Australia, has a high prevalence of cardiovascular disease. The objective of this study was to explore the health care challenges and needs of Arabic-speaking immigrants with cardiovascular disease (CVD), using a comparative approach with English-speaking patients with CVD as the comparable group. Methods: Participants were recruited from community settings in Melbourne, Australia. Face-to-face semi-structured individual interviews were conducted at the recruitment sites. All interviews were audio-taped, transcribed, and coded thematically. Results: 29 participants with CVD were recruited; 15 Arabic-speaking and 14 English-speaking. Arabic-speaking immigrants, and to a lesser extent English-speaking patients with CVD may have specific health care challenges and needs. Arabic-speaking immigrants’ health care needs include: effective health care provider (HCP)-patient communication, accessible care, participation in decision-making, and empowerment. English-speaking participants viewed these needs as important for CVD management. However, only a few English-speaking participants cited these needs as unmet health care needs. Conclusion: This study suggests that Arabic-speaking immigrants with CVD may have unique needs including the need for privacy, effective HCP-patient communication that takes into account patients’ limited English proficiency, and pharmacist-physician collaboration. Therefore, there may be a need to identify a health care model that can address these patients’ health care challenges and needs. This, in turn, may improve their disease management and health outcomes.
