Smoking substantially inhibits the activities of both monamine oxidase (MAO) A and B enzymes.

Aims of this study: to compare MAO activities and nicotine and cotinine in peripheral blood of smoking and nonsmoking pregnant women, in their placenta and in cord blood and relate them with the behavior of their newborns being observed during 48 hours after birth.


Study Type: Observational

Primary Outcome Measures:
  • monoamine oxidase markers [ Time Frame: at birth ]

Biospecimen Retention:   Samples Without DNA
plasma DHPG, HVA, 5HIAA, 5HT, cotinine

Enrollment: 59
Study Start Date: March 2004
Study Completion Date: November 2007
Primary Completion Date: November 2007 (Final data collection date for primary outcome measure)
pregnant smokers
pregnant non smokers

Detailed Description:

40 pregnant smoking and 40 pregnant nonsmoking women will be included at the end of the 2nd trimester.

Assessments: smoking characteristics, plasma cotinine, DHPG, DOPAC, 5HIAA concentrations reflecting MAOA activity and platelet MAOB activity will be measured just after inclusion (end of 2nd trimester), just before delivery in venous maternal blood and just after delivery in cord blood.

The newborns' behavior (wellbeing) will be assessed every 8 hour after birth for 2 days.

Comparisons will be made between smoking and nonsmoking women and their newborns.
