Determinants of post-migration changes in dietary and physical activity behaviours and implications for health promotion: Evidence from Australian residents of sub-Saharan African ancestry

Physical activity amongst culturally and linguistically diverse communities in Australia: a scoping review

BACKGROUND

Australia's overseas-born population continues to grow. This population is disproportionately affected by chronic, non-communicable diseases. Physical activity is the cornerstone of all chronic disease management. Engaging people from culturally and linguistically diverse (CALD) backgrounds in physical activity is an important public health objective. The purpose of this scoping review was to examine the factors that shape physical activity participation among people from CALD backgrounds in Australia.

METHODS

This scoping review followed Arksey and O'Malley's framework. Medline, Embase and CINAHL were searched with key words relating to 'physical activity', 'CALD' and 'Australia' in July 2021 and again in February 2022 for qualitative studies published in English since 2000. Exclusion criteria were: participants < 18 years old, studies specifically focusing on populations with health issues, pregnant or postpartum states. Methodological quality of included studies was evaluated using the Critical Appraisal Skills Programme with the purpose of informing future research. Data extracted from each study were analysed thematically and results were interpreted using Acculturation theory.

RESULTS

Of the 1130 studies, 17 met the inclusion criteria. Findings from each study were captured in three themes: Perceptions of physical activity; Acceptability and Appropriateness; and Access. Following migration, a decrease in physical activity, especially leisure-time activity, was reported. Common factors influencing physical activity engagement included perceptions of physical activity and wellbeing; language, financial and environmental barriers; as well as social, cultural, and religious considerations.

CONCLUSION

This review identified several factors which may interact and contribute to the decline in self-reported physical activity upon migration. Findings from this review may be used to inform future health promotion initiatives targeting people from CALD backgrounds. Future research may benefit from devising a shared definition of physical activity and studying different CALD communities over time.

Post-Migration Changes in Dietary Patterns and Physical Activity among Adult Foreign Residents in Niigata Prefecture, Japan: A Mixed-Methods Study

The migrant population of Japan is gradually increasing, but it is not well known how and why diet and physical activity (PA) change post-migration. Therefore, this study used a mixed-method approach to investigate the changes in dietary patterns and PA through a web- and paper-based survey (n = 128) and understand the contextual factors for those changes through semi-structured interviews (n = 21). Descriptive and thematic analyses of quantitative and qualitative data were conducted, respectively. The majority of survey (57.8%) and interview (66.7%) participants were female, and the mean duration of stay in Japan was 5 and 3.6 years, respectively. The survey revealed an increased consumption of foods attached to Japanese culture, frozen and microwavable food, and a reduced consumption of fruits. We identified environmental (availability, accessibility, and affordability of foods; food safety and diet-related information; and climate), individual (living status; post-migration lifestyle; and food preferences and limitations), or socio-cultural (relationships with Japanese people; cultural differences; and religious influences) factors that impact diet changes. Language proficiency and the duration of stay shape dietary behaviors. Determinants of PA changes were climate, lifestyle, and the influence of Japanese culture. In conclusion, immigrants in Japan experience post-migration diet and PA changes, and this study adds knowledge about how and why such changes occur.

"I am not really into the government telling me what I need to eat": exploring dietary beliefs, knowledge, and practices among ethnically diverse communities in England

BACKGROUND

Communities with diverse ethnicity in high-income countries are disproportionately affected by poor diet-related health outcomes. In England, the United Kingdom's government's healthy eating dietary resources are not well accepted and are underutilised among this population. Thus, this study explored perceptions, beliefs, knowledge, and practices around dietary intake among communities with African and South Asian ethnicity residing in Medway, England.

METHODS

This qualitative study generated data from 18 adults aged 18 and above using a semi-structured interview guide. These participants were sampled using purposive and convenience sampling strategies. All the interviews were conducted in English over the telephone, and responses were thematically analysed.

RESULTS

Six overarching themes were generated from the interview transcripts: eating patterns, social and cultural factors, food preferences and routines, accessibility and availability, health and healthy eating, and perceptions about the United Kingdom government's healthy eating resources.

CONCLUSION

The results of this study indicate that strategies to improve access to healthy foods are required to improve healthy dietary practices among the study population. Such strategies could help address this group's structural and individual barriers to healthy dietary practices. In addition, developing a culturally responsive eating guide could also enhance the acceptability and utilisation of such resources among communities with ethnic diversity in England.

Food behaviours and eating habits among Sub-Saharan African migrant mothers of school-aged children in South Australia

Overweight, obesity and chronic conditions like diabetes, stroke and heart disease represent a significant burden to public health. Traditional foods and healthy dietary habits can reduce the risk of these conditions. Therefore, this study aimed to explore traditional food patterns and eating habits among Sub-Saharan African migrant mothers of school-aged children in South Australia. The study was a qualitative inquiry that used face-to-face interviews with 15 mothers of school-aged children in South Australia. Snowballing was used to sample participants, and data were audio-recorded, transcribed verbatim, coded, and analysed thematically. Four broad themes described participants' food behaviours and eating habits, including maintaining traditional food patterns, changes in traditional food patterns and eating habits, concerns with food environments in Australia, and challenges with traditional food availability and access in Australia. This study found that although mothers were committed to maintaining their traditional foods, they found it increasingly difficult to continue such habits. Participants reported challenges as their children are increasingly demanding westernised foods. While some parents pushed back against such demands from their children, others felt helpless and relented. Some views showed that food environments, food systems, access, and scarcity of traditional foods in Australia influenced the participants' food patterns and eating habits. Appropriately tailored healthy eating health promotion actions targeting school-aged children and mothers in this population need to consider their food contexts. Promoting the use of traditional foods, their preparation practices, and processing might be helpful in this community when developing healthy eating programs.

Self-Care of African Immigrant Adults with Chronic Illness

This cross-sectional study aims to describe the self-care of adult African immigrants in the US with chronic illness and explore the relationship between acculturation and self-care. A total of 88 African immigrants with chronic illness were enrolled. Self-care was measured with the Self Care of Chronic Illness Inventory v3 and the Self-Care Self-Efficacy scale. Scores are standardized 0 to 100 with scores >70 considered adequate. Acculturation was measured using a modified standardized acculturation instrument and predefined acculturation proxies. The self-care scores showed adequate self-care, with the mean scores of 78.6, 77.9, and 75.6 for self-care maintenance, monitoring, and management. Self-care self-efficacy mean score was 81.3. Acculturation was not significantly associated with self-care. Self-care self-efficacy was a strong determinant of self-care maintenance (p < .0001), monitoring (p < .0001), and management (p < .0001). The perception of inadequate income was a significant determinant of poor self-care management (p = .03). Self-care self-efficacy and perceived income adequacy were better determinants of self-care than acculturation.

Developing a Complex Understanding of Physical Activity in Cardiometabolic Disease from Low-to-Middle-Income Countries-A Qualitative Systematic Review with Meta-Synthesis

Physical activity behaviour is complex, particularly in low-resource settings, while existing behavioural models of physical activity behaviour are often linear and deterministic. The objective of this review was to (i) synthesise the wide scope of factors that affect physical activity and thereby (ii) underpin the complexity of physical activity in low-resource settings through a qualitative meta-synthesis of studies conducted among patients with cardiometabolic disease living in low-to-middle income countries (LMIC). A total of 41 studies were included from 1200 unique citations (up to 15 March 2021). Using a hybrid form of content analysis, unique factors (n = 208) that inform physical activity were identified, and, through qualitative meta-synthesis, these codes were aggregated into categories (n = 61) and synthesised findings (n = 26). An additional five findings were added through deliberation within the review team. Collectively, the 31 synthesised findings highlight the complexity of physical activity behaviour, and the connectedness between person, social context, healthcare system, and built and natural environment. Existing behavioural and ecological models are inadequate in fully understanding physical activity participation in patients with cardiometabolic disease living in LMIC. Future research, building on complexity science and systems thinking, is needed to identify key mechanisms of action applicable to the local context.

Food environment interactions after migration: a scoping review on low- and middle-income country immigrants in high-income countries

Objective:

To map and characterise the interactions between the food environment and immigrant populations from low- and middle-income countries living in high-income countries.

Design:

A scoping review was carried out following the framework outlined by Arksey and O’Malley, as well as Levac et al. Peer-reviewed studies in English published between 2007 and 2021 were included. Two reviewers screened and selected the papers according to predefined inclusion criteria and reporting of results follows the PRISMA-ScR guidelines. A ‘Best fit’ framework synthesis was carried out using the Analysis Grid for Environments Linked to Obesity (ANGELO) framework.

Setting:

High-income countries.

Participants:

Immigrants from low- and middle-income countries.

Results:

A total of sixty-eight articles were included, primarily based in the USA, as well as Canada, Australia and Europe, with immigrants originating from five regions of the globe. The analysis identified three overarching themes that interconnected different aspects of the food environment in addition to the four themes of the ANGELO framework. They demonstrate that in valuing fresh, healthy and traditional foods, immigrants were compelled to surpass barriers in order to acquire these, though children’s demands, low incomes, time scarcity and mobility influenced the healthiness of the foods acquired.

Conclusion:

This study brought together evidence on interactions between immigrant populations and the food environment. Immigrants attempted to access fresh, traditional, healthier food, though they faced structural and family-level barriers that impacted the healthiness of the food they acquired. Understanding the food environment and interactions therein is key to proposing interventions and policies that can potentially impact the most vulnerable.

Pre- and Post-Migration Influences on Weight Management Behaviours before and during Pregnancy: Perceptions of African Migrant Women in England

The prevalence of overweight/obesity is high among Black women in England, who also face high risks of pregnancy and childbirth complications. This study explored African migrant women’s perceptions of pre- and post-migration influences on their weight-related behaviours and weight management support during pregnancy. Interviews were conducted with women of child-bearing age from Ghana, Nigeria, and Cameroon (n = 23). Data were analysed using thematic analysis. Four themes were identified: changing dietary behaviours after migration, changing physical activity (PA) behaviours after migration, increased discourse on obesity, and weight management advice and support received. Navigating a new food environment, interactions with other populations in England, and the need to socialise influenced changes in dietary behaviours. Participants considered that living in England ‘makes you lazy’ due to its obesogenic environment, while increased discourses on obesity heightened weight awareness. Women struggled to relate to dietary advice from midwives but found PA advice useful. Relatives provided valuable support but could influence unhealthy weight-related practices. There is a need for interventions addressing gaps in weight management support for these women, especially considering their migrant backgrounds and multicultural identities. Further research is needed to understand their unique challenges, and collaborations with relatives could inform the development of effective weight management interventions.
