Barriers and facilitators of lifestyle management among adult South Asian migrants living with chronic diseases: A mixed-methods systematic review.

BACKGROUND AND AIM: South Asian migrants have a higher prevalence of chronic diseases than Caucasians. Despite much literature that has explored challenges in chronic disease management amongst the South Asian population in the past decades, their chronic disease management is still suboptimal. Understanding their determinants of disease management behaviour using the Theoretical Domains Framework will inform the development of a culturally sensitive intervention relevant to consumer-end-users. This study aimed to synthesise qualitative and quantitative studies on chronic disease management among adult South Asian immigrants. METHODS: A mixed-methods systematic review was conducted using electronic databases. The Mixed Methods Appraisal Tool assessed the quality of the included studies. Quantitative data were transformed into qualitative data and analysed thematically. Subthemes were mapped in the Theoretical Domains Framework presenting barriers and facilitators under each theme. RESULTS: 18293 studies were identified, of which 37 studies were included. The barriers and facilitators identified were categorised into four overarching themes: patient-provider interaction and relationship (e.g., complex language use by health professionals), the impact of migration (e.g., weather conditions had an impact on engagement with physical activity), heritage-based practices (e.g., an obligation to consume energy-dense food in social gatherings), and chronic disease management strategies (e.g., lack understanding of appropriate disease management strategies). CONCLUSION: This review provides a comprehensive understanding of the complexity of chronic disease management among South Asian migrants and insights into developing multifaceted interventions to address barriers to chronic disease management, guiding the healthcare professionals in helping overcome South Asians perceived barriers to managing chronic disease in the host countries.

Dietary management of type 2 diabetes mellitus among South Asian immigrants: A mixed-methods study.

AIMS: There is a high prevalence of South Asian immigrants in Australia living with type 2 diabetes mellitus, with the dietary management of the condition presenting as a key challenge. However, their current dietary patterns and barriers to diabetes self-management are unclear. Therefore, this study aims to (i) investigate current dietary patterns and (ii) explore barriers and facilitators to dietary management in this population. METHODS: A concurrent mixed-methods study comprising three 24-h dietary recalls and a semi-structured interview for each self-identified South Asian immigrant adult with diabetes recruited across Victorian primary care clinics and social media to address the aforementioned two aims. Dietary recall data were converted into food groups using Foodworks, and data analysed in SPSS. Qualitative data were thematically analysed using NVivo. RESULTS: Among 18 participants recruited, 14, 16 and 17 participants had grain, fruit and dairy intake lower than daily Australian recommendations, respectively. These findings echoed qualitative data that participants viewed diabetes management as reducing carbohydrate intake. Participants reported difficulties incorporating diabetes-related dietary and lifestyle recommendations into their routine and a lack of knowledge about available organisational support. They mentioned challenges in receiving social support from families and friends and relied on support from health professionals. Facilitators included proficiency in nutrition information label reading and self-blood glucose monitoring skills. CONCLUSION: Enhancing the accessibility to organisational support, facilitating the adaption of dietary recommendations into individuals' routines, and strengthening support from health professionals are essential components in intervention development to improve diabetes management for South Asians.
