Disparities within the region
When looking at populations in the Western Pacific, stark disparities become apparent. Diabetes prevalence is more than 10% in almost all the Pacific Island countries – Cook Islands, Fiji, Marshall Islands, Nauru, Samoa, Tonga and Tuvalu. Particularly vulnerable Pacific Islander populations face a higher risk of developing type 2 diabetes earlier compared to their counterparts in Australia and other regions. Furthermore, people in these communities often experience more severe diabetes-related complications and a higher mortality rate because of these complications. Cardiovascular diseases (CVD) and chronic kidney disease (CKD) are among the most common complications people with diabetes develop.
Lifestyle factors found in other regions of the world also contribute to the high incidence of diabetes in the Western Pacific. Chiefly, Western lifestyles with poor dietary choices and eating more highly processed foods rich in sugars and unhealthy fats have become more prevalent with the advent of globalisation.
Diabetes impact on Indigenous People
One distinctive feature of the Western Pacific region is that Indigenous Peoples make up the majority in most Pacific Island countries, where genetics also plays a role with certain populations at greater risk of developing type 2 diabetes. Indigenous Peoples account for over 476 million in 90 countries, and diabetes is now one of the most common health disparities that disproportionately impact these populations.
In Papua New Guinea, the Tolai, the Indigenous People of East New Britain, are an example of this susceptibility to develop diabetes. They are recognised as having a predisposed risk of type 2 diabetes on top of their risk as Pacific Islanders and Indigenous people. Looking at diabetes complications, East New Britain has the highest recorded rate of type 2 diabetes and diabetes related amputations throughout PNG.
Additionally, socioeconomic factors can impact health outcomes. Diabetes disproportionately affects isolated and difficult-to-reach communities with limited access to education, resources, and healthcare. Governments have implemented action plans, including national plans, to increase early diagnosis and improve health outcomes. For instance, in 2013, Australia launched the Western Pacific Diabetes Declaration. The plan committed AUD 25 million over four years to combat NCDs, including diabetes, through education, screening, and strengthening the healthcare system.
