Type 2 diabetes (T2DM) is a major global health issue and the cost to community is high and escalating. The Asia-Pacific region carries a high disease burden, with more than 60% of the global diabetic population living in Asian region. The onset of T2DM is gradual, with most individuals progressing through a state of pre-diabetes. A National Survey conducted in China in 2010 revealed that 50.1% of people aged 18 or older have pre-diabetes. People with pre-diabetes, defined as having impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or elevated glycated haemoglobulin (HbA1C) , are at increased risk of developing T2DM and its associated complications, such as heart diseases and retinopathy, which can develop even in the absence of progression to overt T2DM. Hence, it is essential that people with pre-diabetes are targeted for early intervention to prevent T2DM and related complications.~Obesity is a major risk factor for developing T2DM. International trials demonstrate that lifestyle interventions (which includes diet, physical activity and behavioural modification components) targeting at least 5% weight loss in individuals with pre-diabetes can reduce 3-year diabetes incidence by 58%. Growing evidence suggests that smartphones may be a promising platform for delivery of behavioural lifestyle intervention to achieve weight loss.~This project aims to translate the evidence-based diabetes prevention strategies into community setting and utilize mobile health technology to reduce diabetes risks in Hong Kong.
Type 2 diabetes (T2DM) is a serious chronic condition and one of the world's fastest growing health problems. The onset of T2DM is gradual, with most individuals progressing through a state of pre-diabetes, which provides an important window of opportunity for the prevention of T2DM and its complications. This project aims to translate the evidence-based diabetes prevention strategies into community setting and utilize mobile health technology to reduce diabetes risks in Hong Kong.
