Maternal Lifestyle Study (MLS)
MLS was a longitudinal multi-site observational study of the long-term effects of in-utero exposure to cocaine on child development. MLS was conducted at four geographically diverse sites across the United States of America. Participants were identified during the newborn period while in the hospital and consisted of around 1,400 infant-mother dyads. Baseline assessment occurred from 1993 to 1995 and there were follow-ups of caregivers, children and the environment from one month to 16 years after baseline.
