Our primary conclusion is that there is a lack of compelling evidence that incentives of any form represent a compelling NCD reduction strategy .
The rising epidemic of non-communicable diseases ( NCDs ) poses substantial health and economic challenges to both individuals and society .
Application of incentive-based strategies based on traditional and behavioural economic theory has emerged as a potential strategy to address rising rates of NCDs .
Yet , whether or not incentives truly represent a promising strategy for addressing NCDs has not been systematic ally addressed nor is it clear whether certain behavioural economic strategies outperform others or simply offering a cash-based incentive for meeting a goal .
In this systematic review we aim to determine whether there is an evidence base for any of these strategies .
Healthy habits: efficacy of simple advice on weight control based on a habit-formation model
Objective : To evaluate the efficacy of a simple weight loss intervention , based on principles of habit formation . Design : An exploratory trial in which overweight and obese adults were r and omized either to a habit-based intervention condition ( with two subgroups given weekly vs monthly weighing ; n=33 , n=36 ) or to a waiting-list control condition ( n=35 ) over 8 weeks . Intervention participants were followed up for 8 months . Participants : A total of 104 adults ( 35 men , 69 women ) with an average BMI of 30.9 kg m−2.Intervention : Intervention participants were given a leaflet containing advice on habit formation and simple recommendations for eating and activity behaviours promoting negative energy balance , together with a self-monitoring checklist . Main outcome measures : Weight change over 8 weeks in the intervention condition compared with the control condition and weight loss maintenance over 32 weeks in the intervention condition . Results : At 8 weeks , people in the intervention condition had lost significantly more weight ( mean=2.0 kg ) than those in the control condition ( 0.4 kg ) , with no difference between weekly and monthly weighing subgroups . At 32 weeks , those who remained in the study had lost an average of 3.8 kg , with 54 % losing 5 % or more of their body weight . An intention-to-treat analysis ( based on last-observation-carried-forward ) reduced this to 2.6 kg , with 26 % achieving a 5 % weight loss . Conclusions : This easily disseminable , low-cost , simple intervention produced clinical ly significant weight loss . In limited re source setting s it has potential as a tool for obesity management
