Brief Summary

Maternal smoking during pregnancy (MSDP) increases the risk of adverse pregnancy and birth outcomes and may have long-lasting effects in the offspring.Financial incentives may increase smoking abstinence rate in pregnancy and therefore reduce MSDP related negative health effects. This is a randomized open label study comparing financial incentives for smoking abstinence with no financial incentives for smoking abstinence.Research objectives

  1. 1.To test the efficacy of financial incentives on smoking abstinence rate among pregnant smokers;
  2. 2.To explore the heterogeneity of efficacy according to individual characteristics: socioeconomic status, social background, smoking characteristics, personality traits, time and risk preferences to determine profiles of women which could benefit best from this kind of intervention;
  3. 3.To provide a cost-benefit analysis based on the cost of newborn and children disease due to maternal smoking during pregnancy.
