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 .
A randomized study of financial incentives to increase physical activity among sedentary older adults.
OBJECTIVE Less than half of all U.S. adults meet public health recommendations for physical activity , and even fewer older adults ( aged 50 years and over ) are sufficiently active . Because inactivity increases the risk of costly medical complications , successful efforts to increase physical activity among older adults may potentially be cost-effective . We sought to test if financial incentives for walking could increase physical activity among sedentary older adults . METHODS We conducted a 4-week r and omized controlled study using pedometers .  A total of 51 adults age 50 + from the Raleigh-Durham area of North Carolina participated in the study in April-May 2007 . Individuals were r and omized into one of two arms . The control group received a fixed payment of $ 75 ; the intervention group received a fixed payment of $ 50 plus up to $ 25 more per week depending on the number of weekly aerobic minutes  , defined as 10 + minutes of continuous walking or jogging . RESULTS The control group logged 2.3 h per week , on average . The intervention group logged 4.1 h per week and received an additional weekly payment of $ 17.50 , on average . CONCLUSION Modest financial incentives tied to aerobic minutes are an effective , and potentially cost-effective , approach for increasing physical activity among sedentary older adults
