Personal financial incentives can change habitual health-related behaviors and help reduce health inequalities .
However , their role in reducing disease burden is potentially limited given current evidence that effects dissipate beyond three months post-incentive removal
OBJECTIVES Uncertainty remains about whether personal financial incentives could achieve sustained changes in health-related behaviors that would reduce the fast-growing global non-communicable disease burden .
This review aims to estimate whether : i. financial incentives achieve sustained changes in smoking , eating , alcohol consumption and physical activity ; ii .
effectiveness is modified by ( a ) the target behavior , ( b ) incentive value and attainment certainty , ( c ) recipients ' deprivation level .
Effects of voucher-based incentives on abstinence from cigarette smoking and fetal growth among pregnant women.
AIMS This study examined whether voucher-based reinforcement therapy ( VBRT ) contingent upon smoking abstinence during pregnancy is an effective method for decreasing  maternal smoking during pregnancy and improving fetal growth . DESIGN , SETTING AND PARTICIPANTS A two-condition , parallel-groups , r and omized controlled trial was conducted in a university-based research clinic . A total of 82 smokers entering prenatal care participated in the trial . INTERVENTION Participants were assigned r and omly to either contingent or non-contingent voucher conditions . Vouchers exchangeable for retail items were available during pregnancy and for 12 weeks postpartum . In the contingent condition , vouchers were earned for biochemically verified smoking abstinence ; in the non-contingent condition , vouchers were earned independent of smoking status . MEASUREMENTS Smoking outcomes were evaluated using urine-toxicology testing and self-report . Fetal growth outcomes were evaluated using serial ultrasound examinations performed during the third trimester . FINDINGS Contingent vouchers significantly increased point-prevalence abstinence at the end-of-pregnancy ( 41 % versus 10 % ) and at the 12-week postpartum assessment ( 24 % versus 3 % ) . Serial ultrasound examinations indicated significantly greater growth in terms of estimated fetal weight , femur length and abdominal circumference in the contingent compared to the non-contingent conditions . CONCLUSIONS These results provide further evidence that VBRT has a substantive contribution to make to efforts to decrease maternal smoking during pregnancy and provide new evidence of positive effects on fetal health
