| description | Introduction
China is the largest tobacco consumer in the world, and tobacco poses
a serious threat to the health of pregnant women. However, there are relatively
few domestic studies on smoking during pregnancy and childbirth outcomes
among pregnant women. The purpose of this study was to analyze the effect of
active and passive smoking on pregnant women and their pregnancy outcomes,
providing evidence and recommendations for intervention measures.
Methods
This was a cohort study in Shanghai from April 2021 to September 2023.
According to the smoking status of pregnant women, they were divided into
three groups: active smokers, passive smokers and non-smokers. A self-designed
questionnaire was utilized to conduct the survey, and their pregnancy outcomes
were tracked and followed up.
Results
A total of 3446 pregnant women were included in this study, among which
2.1% were active smokers, 43.5% were passive smokers, and 54.4% were nonsmokers.
The average age of the pregnant women was 29.9 years, and 41.2%
had a university degree or higher. The education level of active smokers and
passive smokers was significantly lower than that of non-smokers (p<0.05).The
average gestational age of non-smokers was 38.6 weeks, and the birth weight was
3283.2 g, which was higher than those of active smokers and passive smokers
(p<0.05). Logistic regression analysis showed that passive smoking increased the
likelihood of preterm birth (AOR=1.38; 95% CI: 1.05–1.81), low birth weight
(AOR=1.53; 95% CI: 1.10–2.12), and intrauterine growth restriction (AOR=1.35;
95% CI: 1.02–1.79), while active smoking increased the likelihood of preterm
birth (AOR=2.98; 95% CI: 1.50–5.90), low birth weight (AOR=4.29; 95% CI:
2.07–8.88), intrauterine growth restriction (AOR=2.70; 95% CI: 1.37–5.33) , and
birth defects (AOR=2.66; 95% CI: 1.00–6.97).
Conclusions
Our findings illustrate that active and passive smoking can lead to
adverse pregnancy outcomes. This study provides data on the relationship between
smoking during pregnancy and delivery outcomes among pregnant women. In
the future, we need more effective strategies to protect pregnant women from
the harm of tobacco. |
