Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will receive regular semi-personalized lifestyle reminders sent via mobile phone text messages for 6 months. Each participants will receive 4 text messages per week for 6 months. These will be sent at random times of the day (9.00am, 12noon, 3.00pm, 5.00pm) and on random days of the week (Monday through Friday). Non-smokers will receive two general messages, one nutritional message and one physical activity message per week. Smokers will receive one general message, one nutritional message, one physical activity message and one smoking cessation message per week. Messages will be practical in nature, less than 160 characters in length and will be generic for varying age and genders. Prior to study commencement, a bank of 100 messages will be developed based on scientific literature and multidisciplinary expert review and finalised via a qualitative review process.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be approached directly by the research assistant during a very brief face to face meeting during the inpatient stay. The researcher will establish whether the patient is interested in volunteering and if they consent they will be randomised.
The patients will be allocated by central randomisation by computer and the on site staff will not have access to the details of randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by computer software (computerised sequence generation).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
