Nutrition for pre-diabetes


This project is led by PhD Candidate Mari Somerville. 

Prediabetes is a state of increased risk of type 2 diabetes (1). Between 2-4 million people are living with prediabetes in Australia (2,3). Many people with prediabetes are unaware of their condition, and may not seek treatment to delay the onset of type 2 diabetes. However, once diagnosed, prediabetes may be effectively managed by improved diet quality and physical activity (4). Despite knowing how to manage prediabetes and prevent type 2 diabetes, it is unclear what level of care people with prediabetes are currently receiving in Australian primary care settings.


The aims of this research are:

  1. To understand patients’ experiences of receiving nutrition care following a prediabetes diagnosis.
  2. To explore health care provider practices and views towards managing people with prediabetes in an urban Australian general practice setting.
  3. To determine patients’ preferences for receiving nutrition care for chronic diseases in Australian primary care settings.


This research will impact patients with prediabetes as the findings from this work will shape future health care practices to better support people with prediabetes. This research will impact primary health care providers, including general practitioners, nurses and dietitians, by exploring ways these providers can better support their patients with prediabetes. This research will impact the Australian healthcare system as it will shed light on current gaps in care delivery and identify ways to improve healthcare services.
