Tobacco chewing in pregnancy

K Krishna

    British Journal of Obstetrics and Gynaecology
    |October 1, 1978
    PubMed
    Summary

    Pregnant women who chewed tobacco faced significantly higher stillbirth rates and lower infant birth weights. This practice also resulted in a reduced male to female infant sex ratio, largely due to premature births.

    Area of Science:

    • Obstetrics and Gynecology
    • Public Health
    • Reproductive Health

    Background:

    • Tobacco use during pregnancy is a significant public health concern.
    • Understanding the specific risks of different forms of tobacco use, like chewing, is crucial for maternal and infant health.
    • Existing research often focuses on smoking, necessitating further investigation into tobacco chewing's impact.

    Purpose of the Study:

    • To investigate the adverse effects of tobacco chewing during pregnancy on pregnancy outcomes.
    • To quantify the impact on stillbirth rates, infant sex ratio, and birth weight.
    • To determine the contributing factors to reduced birth weight in offspring of tobacco-chewing mothers.

    Main Methods:

    • A comparative study design was employed.
    • Mothers were categorized based on tobacco chewing habits during pregnancy.
    • Key perinatal outcomes including stillbirth, infant sex ratio, and birth weight were analyzed and compared between groups.

    Main Results:

    • Tobacco-chewing mothers exhibited a significantly elevated stillbirth rate compared to non-users.
    • A notable decrease in the male:female infant sex ratio was observed in the tobacco-chewing group.
    • A substantial reduction in mean birth weight was recorded, primarily attributed to early delivery.

    Conclusions:

    • Tobacco chewing during pregnancy poses severe risks to fetal development and survival.
    • The practice is associated with increased stillbirths, skewed infant sex ratios, and low birth weight due to prematurity.
    • Public health initiatives should address and discourage tobacco chewing among pregnant women to improve maternal and infant outcomes.
