3. Smoking leading cause of preventable death Txt2stop 5800 smokers willing to quit Allocated to txt2stop or control Doubled biochemically validated quitting at six months 10.7% txt2stop versus 4.9% control, relative risk 2.20 (95% CI 1.80 to 2.68), p<0.0001. Implemented UK with over 48,000 users since 2012

4. Systematic review of trials of mobile technology based interventions for health or health care Promising results Physical activity (only short term), hypertension Appropriate disease management for providers (11/25 outcomes showed statistically significant benefits) Clear small benefits appointment reminders. Mixed results few trials.e.g. asthma No clinically important benefits Weight loss Daily medication reminders RR 1.00 (95% CI 0.77 to 1.30)

5. Effects of texting interventions on HBA1C for diabetes

6. Summary Where there is good evidence of benefit strong implementation plans are needed e.g. smoking cessation Lack of evidence in many areas for NCD New and improved NCD interventions needed. Well designed and adequately powered trials to demonstrate the effectiveness of interventions are needed in many areas.
