本研究係在於評估美國密蘇里州聖路易士醫學中心針對吸毒婦女與她們所產下的嬰兒，有否接受戒毒處置與產前治療之服務方案之成效。在研究中，共有一百一十四名吸毒的孕（產）婦與她們所產下的嬰兒被列為觀察對象。其中半數的孕婦在妊娠期間獲得良好的產前檢查並且接受戒毒處置，有百分之二十九點八（三十四名）的孕婦則僅獲得一些產前檢查，另外的百分之二十點二（二十三名）的孕婦則沒有得到任何服務。本研究的結果證明了：同樣是在妊娠期間吸食毒品或酗酒的孕婦，對她們而言，接受良好的產前與戒毒治療處置，遠比不接受這些處置者，有較多機率產下健康嬰兒；同時，藉由方案提供的個案管理服務與戒毒處置治療，社工員協助大部分的案主解決了妊娠期間及生產之後在經濟、住宿、交通、工作、家庭等方面的問題；並且喚起案主對胎兒與自身健康的重視，使案主遠離毒品，同時教導案主照顧嬰兒的技巧，促進案主的親子互動關係。 The case-control study tested the hypothesis about that pregnant women who use drugs during pregnancy， if they received drug treatment and good prenatal care， they will have higher chance to deliver their infants with better health outcome than those women who use drugs during pregnancy without drug treatment and prenantal care. In this study the good prenatal care must be 5 visits. Controls were matched to cases by the pregnant womens' age， para， and race. 100% (114) cases were drug user during pregnancy， 50% (57) cases were received good prenatal care and drug treatment. 29.8% (34) cases were received some prenatal care only. 20.2% (23) cases were received no prenatal care and no drug treatment.
