Some healthcare plans are paying people to stop smoking, to attend pre-natal classes or to lose weight. The idea is that an immediate incentive will be more effective than the delayed incentive of better health, or of avoiding a future complication such as a heart attack. So far, the results are mixed. This study released today tested the effect of paying people in rural Mississippi up to $200 to lose weight, increase physical activity, and improve several other clinical measures. They report that the incentives had little effect, although there was a positive trend for weight loss. Would something like this work for you? Let us know at firstname.lastname@example.org.
