Insights
Paternal smoking is linked to lower birth weight in infants, even when maternal smoking is considered. Maternal smoking increases infant cough risk, but paternal smoking shows no significant association with this respiratory symptom.
Area of Science:
- Pediatrics
- Public Health
- Environmental Health
Background:
- Secondhand smoke exposure is a significant concern for infant health.
- Understanding the distinct impacts of maternal versus paternal smoking is crucial for targeted interventions.
Purpose of the Study:
- To investigate the independent effects of maternal and paternal smoking on infant birth weight and respiratory symptoms.
- To quantify the association between parental smoking habits and infant health outcomes at one month of age.
Main Methods:
- Multivariate analysis of data from 518 couples with one-month-old infants.
- Collected data included parental smoking habits, social class, maternal age, parity, and alcohol consumption.
- Assessed infant birth weight and respiratory symptoms (cough).
Main Results:
- Infants of fathers who smoked were, on average, 113g lighter at birth (95% CI 8-216g), an effect sustained at one month (112g, 95% CI 0-224g), even after accounting for maternal smoking.
- Maternal smoking doubled the likelihood of infant cough (Relative Risk = 2.0, 95% CI 1.05-3.68).
- No significant association was found between paternal smoking and infant cough.
Conclusions:
- Paternal smoking independently contributes to reduced infant birth weight.
- Maternal smoking is a significant risk factor for infant cough.
- Public health strategies should address both maternal and paternal smoking to improve infant health outcomes.
Abstract:
From 518 couples with a 1 month old baby, information was obtained on the couple's smoking habit, social class, age of mother, parity, alcohol consumption during pregnancy and respiratory symptoms of the baby. Allowing for these factors, a multivariate analysis revealed that, even allowing for mother's smoking habit, babies whose father smoked were lighter at birth by an average of 113 g (95% CI 8-216 g) and this effect was unchanged at 1 month (112 g, 95% CI 0-224 g). Babies whose mothers smoked were twice as likely to have a cough (Relative Risk = 2.0, 95% CI 1.05-3.68), than those whose mothers did not, but we failed to find a significant association with the father's smoking habit.
