Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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. Pre-diabetes is a prevalent and potentially reversible condition, 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 a community setting to reduce diabetes risks in Hong Kong Chinese people with pre-diabetes .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Type 2 diabetes (T2DM) is a major non-communicable disease and one of the world's fastest growing health problem. It is associated with significant morbidity, including increased risk of heart disease and stroke, hypertension, retinopathy and blindness, renal failure and leg amputation, which place an enormous burden on individuals, society and the healthcare system. The T2DM trend in Hong Kong mirrors the global trend. It is a major cause of mortality and morbidity with approximately 700,000 people diagnosed with diabetes, representing 10% of Hong Kong's total population.

T2DM is a non-reversible, yet a preventable condition. The onset of T2DM is gradual, with most individuals progressing through a state of 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.

International clinical trials demonstrated that lifestyle interventions targeting at least 5% weight loss in individuals with pre-diabetes can be cost-effective in preventing T2DM. Lifestyle intervention (which includes diet, physical activity and behavioural modification components) and self-management of pre-diabetes has been listed as an effective means of decreasing the incidence of T2DM in the international guidelines on management of pre-diabetes.

The aim of this study is to translate preventive research into effective community-based intervention by setting up a culturally appropriate lifestyle intervention programme for the prevention of T2DM in Hong Kong Chinese adults with pre-diabetes.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

It is a 12-month 2-arm randomised controlled trial, RCT (the lifestyle intervention group and the SMS intervention group) with a 3 year follow up. The programme will proceed in two phases: the intensive intervention phase (0-6 months) and the maintenance phase (7-12 months). During the intensive intervention phase, participants in the lifestyle intervention group will attend 7 group-based interventions plus two sessions of individual face-to-face dietician consultation. During the maintenance phase, participants will receive monthly phone call from the research team.

The SMS intervention group will receive regular SMS during both the intensive intervention and the maintenance phases.
