Summary
This summary is machine-generated.

Pregnant women using cannabis had slightly smaller babies, but it was linked to socioeconomic factors and other substance use, not cannabis itself. Cannabis use during pregnancy is not a major risk factor for pregnancy outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatal Epidemiology
  • Reproductive Health

Background:

  • Cannabis use during pregnancy is a public health concern.
  • Understanding the impact of cannabis on pregnancy outcomes is crucial for clinical guidance.
  • Socioeconomic factors and polysubstance use often confound the effects of specific drug use.

Purpose of the Study:

  • To investigate the association between cannabis use and pregnancy outcomes in a large cohort.
  • To determine if cannabis use independently affects fetal growth and development.
  • To explore the role of socioeconomic status and other substance use in this association.

Main Methods:

  • Retrospective cohort study of 12,885 pregnant women in Copenhagen.
  • Questionnaires assessed alcohol, tobacco, cannabis, and other drug use.

  • Cannabis users were matched with non-users based on age, parity, and study period.
  • Infant outcomes including birthweight, length, and head circumference were compared.

    • Main Results:

    • The prevalence of cannabis use among pregnant women was 0.8%.
    • Cannabis-using mothers were socioeconomically disadvantaged and reported higher rates of other substance use.
    • Infants born to cannabis users showed significantly lower birthweight, length, and head circumference.
    • These differences were eliminated when controlling for maternal tobacco smoking, suggesting tobacco as a confounder.

    Conclusions:

    • Cannabis use during pregnancy is not an independent major prognostic factor for pregnancy outcomes.
    • Cannabis use in this cohort was an indicator of socioeconomic disadvantage and polysubstance use.
    • Maternal tobacco smoking appears to be a significant confounder for the observed effects on fetal growth.
