South Asians (i.e., people who originate from India, Pakistan, Sri Lanka, Nepal, and Bangladesh) have higher cardiovascular disease rates than other populations, and these differences persist in their offspring. Nutrition is a critical lifestyle-related factor that influences fetal development, and infant and child health in early life. In high-income countries such as Canada, nutrition-related health risks arise primarily from overnutrition, most strikingly for obesity and associated non-communicable diseases. Evidence for developmental programming during fetal life underscores the critical influence of maternal diet on fetal growth and development, backed by several birth cohort studies including the Pune Maternal Nutrition Study, the South Asian Birth Cohort Study, and the Born in Bradford Study. Gestational diabetes mellitus is a strong risk factor for type 2 diabetes, future atherosclerosis and cardiovascular disease in the mother and increases the risk of type 2 diabetes in her offspring. Non-pharmacological trials to prevent gestational diabetes are few, often not randomized, and are heterogeneous with respect to design, and outcomes have not converged upon a single optimal prevention strategy. The aim of this review is to provide an understanding of the current knowledge around perinatal nutrition and gestational diabetes among the high-risk South Asian population as well as summarize our research activities investigating the role of culturally-tailored nutrition advice to South Asian women living in high-income settings such as Canada. In this paper, we describe these qualitative and quantitative studies, both completed and underway. We conclude with a description of the design of a randomized trial of a culturally tailored personalized nutrition intervention to reduce gestational glycaemia in South Asian women living in Canada and its implications.

Abstract Background South Asian women are at a high risk of developing gestational diabetes mellitus than other women in Australia. Gestational diabetes affects up to 14–19% of all pregnancies among South Asian, South East Asian, and Arabic populations placing women at risk of adverse pregnancy outcomes. Although, gestational diabetes resolves after childbirth, women with gestational diabetes are up to seven times more likely to develop type 2 diabetes within five to ten years of the index pregnancy. Increasingly, South Asian women are being diagnosed with gestational diabetes in Australia. Therefore, we aimed to gain a better understanding of the lived experiences of South Asian women and their experiences of self-management and their health care providers’ perspectives of treatment strategies. Methods Using an ethnographic qualitative research methodology, semi-structured one-on-one, face-to-face interviews were conducted with 21 health care providers involved in gestational diabetes management and treatment from the three largest tertiary level maternity hospitals in Melbourne, Victoria, Australia. In-depth interviews were conducted with 23 South Asian women post diagnosis between 24–28 weeks gestation in pregnancy. Results Health care providers had challenges in providing care to South Asian women. The main challenge was to get women to self-manage their blood glucose levels with lifestyle modification. Whilst, women felt self-management information provided were inadequate and inappropriate to their needs. Women felt ‘losing control over their pregnancy’, because of being preoccupied with diet and exercise to control their blood glucose level. Conclusions The gestational diabetes clinical practice at the study hospitals were unable to meet consumer expectations. Health care providers need to be familiar of diverse patient cultures, rather than applying the current ‘one size fits all’ approach that failed to engage and meet the needs of immigrant and ethnic women. Future enabling strategies should aim to co-design and develop low Glycaemic Index diet plans of staple South Asian foods and lifestyle modification messages.

Increased Risk

Gestational diabetes mellitus (GDM) is a serious pregnancy complication, in which women without previously diagnosed diabetes develop chronic hyperglycemia during gestation. In most cases, this hyperglycemia is the result of impaired glucose tolerance due to pancreatic β-cell dysfunction on a background of chronic insulin resistance. Risk factors for GDM include overweight and obesity, advanced maternal age, and a family history or any form of diabetes. Consequences of GDM include increased risk of maternal cardiovascular disease and type 2 diabetes and macrosomia and birth complications in the infant. There is also a longer-term risk of obesity, type 2 diabetes, and cardiovascular disease in the child. GDM affects approximately 16.5% of pregnancies worldwide, and this number is set to increase with the escalating obesity epidemic. While several management strategies exist—including insulin and lifestyle interventions—there is not yet a cure or an efficacious prevention strategy. One reason for this is that the molecular mechanisms underlying GDM are poorly defined. This review discusses what is known about the pathophysiology of GDM, and where there are gaps in the literature that warrant further exploration.
