Smoking during pregnancy is linked to poor pregnancy outcomes including low birth weight, very pre-term birth and perinatal death. Statistics show that 45 percent of pregnant women who smoke are under the age of 20 compared to nine percent over the age of 35. Smoking is also strongly linked to low socio-economic status and women from these groups are most likely to carry on smoking during pregnancy. Research shows that people who engage with smoking cessation support services are more likely to quit, but due to the sensitivity and social stigma attached to smoking and pregnancy, these services remain underused. Currently there is a gap in the information provided to pregnant women and information provided specifically to teenagers who are pregnant. Information for pregnant teenagers about smoking and pregnancy and smoking cessation support services are greatly needed.
