Plain English Summary
Background and study aims
Pre-diabetes is a condition where the person is not yet diabetic but is at a great risk to be so. A person with pre-diabetes has high blood sugar but not high enough to be called diabetic. A major way to stop a pre-diabetic from becoming diabetic is to have good amount of daily physical activity and eat a healthy diet. There are many ways to help people live a healthy lifestyle. The aim of this study is to see whether encouraging people through text messages helps them to eat healthily and move more.
Who can participate?
People above the age of 18 who are pre-diabetic
What does the study involve?
Participants are randomly allocated to one of two groups. One group is sent the text messages and the other group does not get any messages. Their blood sugar is measured to see which group benefited more. Both groups also get a standard education session on how to eat healthily and move more.
What are the possible benefits and risks of participating?
The expected side effect is a little pain from the needle when taking blood to test blood sugar.

Intervention
A computer-generated randomization sequence (Matlab randperm version 6) based on Marsaglia's algorithm to randomly allocate patients (1:1) to individually tailored phone messaging or to a control group that received standard life modification advice at baseline visit only.
The intervention is lifestyle modification text messages that are tailored to the participant according to the Trans Theoretical Model (TTM) stage of change. Both control and intervention groups will receive a baseline standard lifestyle modification education session, and both groups take metformin tablets as prescribed by their treating physician.
