Prenatal alcohol use puts mothers and their children at risk for complications during pregnancy, birth, and the neonatal periods. This paper describes a currently implemented community-based pilot program to reduce drinking among pregnant mothers. The program has worked in collaboration with case managers from Crow Wing County Social Services. Participants were required to provide daily breath samples with monetary incentives on alcohol-negative sample submissions. The program has treated four pregnant mothers so far, with an average of 94 percent compliance rate and no alcohol-positive breath samples. Future planned adjustments include using a remotely reloadlable debit card to reinforce daily sample submission, switching to completely random monitoring schedules to avoid falsenegative results, and expanding the program service in other counties. The community-based program using mobile technology has promise to increase opportunities to reinforce healthy lifestyle during pregnancy.
