Special Issue Information

Dear Colleagues,  

Type 2 diabetes mellitus (T2D) increases the risk of cardiovascular disease (CVD). Globally, an estimated 17.8 million and 1.4 million deaths were caused by CVD and diabetes, respectively, in 2017—an increase of 21% in CVD and 34% in diabetes from 2007. In Europe, 19.9 million people are anticipated to be living with CVD and 60 million are living with diabetes. CVD costs the UK economy £7.4 billion annually, and the global economic burden of CVD is projected to reach USD 1044 billion by the year 2030—nearly a USD 200 billion rise from 2010. Similarly, the current global cost of diabetes is estimated to be USD 760 billion, and is projected to cost USD 825 billion by 2030.Obesity, especially visceral adipose tissue (VAT), is associated with T2D. The prevalence of obesity and overweight is approximately 25% in the UK, 40% in the US, and 13% worldwide. Obesity is linked to various metabolic abnormalities such as high triglycerides, low high-density lipoprotein cholesterol (HDL-C), elevated blood glucose, and hypertension, referred to as metabolic syndrome. Additionally, insulin resistance (IR), dyslipidaemia and low-grade inflammation often present with obesity and metabolic syndrome. This clustering of abnormalities is often referred to as cardiometabolic disease (CMD) and is highly associated with T2D and CVD. However, obesity is not a choice, and neither is T2D. Misconceptions regarding the onset, management and progression of obesity and type 2 diabetes exist, which reinforce stigma associated with these conditions. To reduce the onset initially, and to support those with established T2D or obesity, we must act. We must consider alternative approaches and strategies in their prevention and treatment. We must not simply assume that the science is static, and should be open to exploring new approaches. To change behaviours is not simply a process of engaging in knowledge and implementation; we must provide an environment which is all encompassing: to promote individual capacity, motivation and opportunity to engage.We propose this Special Issue to fully consider the bio-psycho-social model (Engel, 1977) to understand and work with people living with obesity or diabetes, and to further understand how these factors interact to influence the behaviours that contribute to, or maintain, obesity or type 2 diabetes.For this Special Issue, we call for papers which challenge the status quo: in understanding biology, services, interventions and treatments. We welcome papers which may affect policy, standards and guidelines for obesity or T2D; which may influence health professional training and supervision needs; or may explore the role of communication to the public, to patients or to health professionals.We welcome intervention studies, qualitative and quantitative empirical research, as well as reviews, position papers, brief reports and commentaries.

Systematic Review
Cultural Identity Conflict Informs Engagement with Self-Management Behaviours for South Asian Patients Living with Type-2 Diabetes: A Critical Interpretative Synthesis of Qualitative Research Studies

The prevalence of type-2 diabetes (T2D) is increasing, particularly among South Asian (SA) communities. Previous research has highlighted the heterogeneous nature of SA ethnicity and the need to consider culture in SA patients’ self-management of T2D. We conducted a critical interpretative synthesis (CIS) which aimed to a) develop a new and comprehensive insight into the psychology which underpins SA patients’ T2D self-management behaviours and b) present a conceptual model to inform future T2D interventions. A systematic search of the literature retrieved 19 articles, including 536 participants. These were reviewed using established CIS procedures. Analysis identified seven constructs, from which an overarching synthesizing argument ‘Cultural Conflict’ was derived. Our findings suggest that patients reconstruct knowledge to manage their psychological, behavioural, and cultural conflicts, impacting decisional conflicts associated with T2D self-management and health professional advice (un)consciously. Those unable to resolve this conflict were more likely to default towards cultural identity, continue to align with cultural preferences rather than health professional guidance, and reduce engagement with self-management. Our synthesis and supporting model promote novel ideas for self-management of T2D care for SA patients. Specifically, health professionals should be trained and supported to explore and mitigate negative health beliefs to enable patients to manage social-cultural influences that impact their self-management behaviours.
