Arms Assigned Interventions
Experimental: Short Message Service (SMS)
A computer-based text message database was created. Messages prompted subjects to get rid of smoking and eating out, to persevere with the quit smoking attempt with the emphasis on the peer pressure on the smoking cessation by the smoking ban in restaurants. They encouraged them to overcome the barriers of healthy eating diet and physical activity with a block of text messages.

Detailed Description:

Mobile phone use is almost a routine part of society worldwide. All mobile phones can deliver and receive short-messaging service text messages, providing a perfect medium for delivering information and support. Since short-messaging service is little exploited in clinical research or practice in Chinese population, this study examined the effectiveness of one-way messaging which is less expensive and is easier to undertake. We aimed to determine the effectiveness of using SMS to provide pre-diabetes and diabetes information by promoting healthy lifestyle modification and reducing the two-hour post-glucose loading plasma glucose, the risk of acquiring Type 2 Diabetes Mellitus among professional drivers with pre-diabetes.
