The Healthy Babies Project is an effectiveness trial designed to determine the effects of clinic-based behavioral counseling on environmental tobacco smoke (ETS) exposure among low-SES infants of smoking mothers, as measured by parent reports and babies' urine cotinine values. One hundred and fifty women with children age three and younger have been recruited from two community clinic populations receiving well-baby care. Mothers were randomly assigned to a usual-treatment control group or to an experimental/counseling group which receives seven counseling sessions over six months. Counseling is administered by trained clinic staff. Mothers are assisted in setting personal goals for reducing their infants' ETS exposure. Contingency contracting, shaping, and stimulus control are incorporated into individualized sessions which encourage mothers to decrease their babies' exposure to ETS. All participants are interviewed at baseline, 3-months (mid-intervention), 6-months (post-intervention), and 12-months (follow-up). Urine samples are obtained from babies at each measurement for cotinine analysis. Mothers also are asked to provide saliva samples for cotinine analysis if they report smoking cessation. Nicotine air monitors are placed in subjects' homes for the duration of their participation. The specific aims of this project are: 1) to determine the effects of a clinic-based behavioral counseling program on home ETS exposure among low-SES babies, as measured by parent reports and babies' urine cotinine assays, 2) to validate parent-reported ETS exposure measures using urine cotinine assays and environmental nicotine monitors, 3) to determine the effects of participation on mothers' level of smoking and proportion of mothers who quit smoking, 4) to explore health outcome measures associated with decreased ETS exposure.
