Study Arms (2)

Short Message Service (SMS)

EXPERIMENTAL

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.

Behavioral: Short Message Service (SMS)

Standard usual care
