INTRODUCTION Many women continue tobacco use during pregnancy despite known adverse consequences on neonatal growth and development. Testing meconium, the first neonatal feces, for tobacco biomarkers offers objective evidence of prenatal tobacco exposure. However, relationships between the amount, frequency, and timing of cigarette smoking during gestation(More)
INTRODUCTION While much has been written about postpartum smoking relapse prevention, few have examined changes in smoking behavior from pregnancy (third trimester) through 9 months postpartum among pregnant smokers, particularly for the large number of women who decrease tobacco consumption during pregnancy but do not quit altogether. METHODS Data were(More)
This study examined the association between fetal tobacco exposure (FTE) and focused attention at 9 months of child age, and the role of child sex and infant behavioral reactivity as potential moderators of this association. Data were obtained from 203 mothers and their infants (105 fetally exposed and 98 non-exposed) on infant focused attention and(More)
Introduction Many studies on prenatal tobacco exposure (PTE) effects have relied on single item retrospective measures of PTE. However, it is unclear how these single item measures may relate to more intensive maternal self-reports and to biological markers of maternal use and/or fetal exposure. It is also unclear whether these measures may be more valid(More)
BACKGROUND Cannabis is the most frequently used illicit drug among pregnant women, but data describing the effects of prenatal cannabis exposure and concurrent nicotine and cannabis exposures on neonatal growth are inconsistent. Testing of meconium, the first neonatal feces, offers objective evidence of prenatal cannabis exposure, but the relative ability(More)
The purpose of this study was to examine the association between prenatal exposure to cigarettes and heart rate during an object manipulation task at 9 months of age. Second-by-second heart rate was recorded for 181 infants who were prenatally exposed to cigarettes and 77 nonexposed infants during the manipulation of four standardized toys. A series of(More)
