Tobacco use

Maternal smoking during pregnancy increases risk of miscarriage, complications in birth and labour (placental problems, premature rupture of membranes, ectopic pregnancy), premature birth, low birth weight, perinatal death (e.g. still birth, sudden infant death after birth) and reduced lung function and chronic breathing problems in newborns. The overall percentage of women who report smoking at the time of their first antenatal booking has decreased consistently from 29.0% in 1995 to a new low of 19.3% in 2011. The percentage of 'unknowns' rose from 5% in 1995 to 14.2% in 2009 before decreasing to 4.8% in 2011- this may include a proportion of smokers.
