    • Public Health
    • Perinatal Medicine

    Background:

    • Maternal smoking during pregnancy is a significant public health concern.
    • Previous research indicates potential adverse effects on pregnancy outcomes.
    • Understanding demographic associations with smoking is crucial for targeted interventions.

    Purpose of the Study:

    • To investigate the prevalence of smoking among women giving birth.
    • To identify demographic factors associated with smoking during pregnancy.
    • To examine the relationship between maternal smoking and various pregnancy and neonatal outcomes.

    Main Methods:

    • A sample of 1248 women giving birth to live-born infants was analyzed.
    • Data on smoking habits throughout pregnancy were collected.

    Related Experiment Videos

  • Statistical analyses were performed to assess associations between smoking, maternal demographics, and infant outcomes.

    • Main Results:

    • Approximately 26% of women smoked throughout pregnancy, with an additional 8% smoking at some point.
    • Smoking was more prevalent among younger mothers, non-European mothers, those with no formal education, lower socioeconomic status, and mothers of ex-nuptial infants.
    • Maternal smoking was associated with decreased birth weight, increased risk of low birth weight (less than 2500g) infants, and a higher risk of spontaneous abortion.

    Conclusions:

    • Maternal smoking during pregnancy is common and linked to specific socio-demographic factors.
    • Smoking during pregnancy poses significant risks, including reduced birth weight and spontaneous abortion.
    • No significant association was found between smoking and labor complications, neonatal respiration onset, resuscitation use, or neonatal infection.
