SMOKING

At Antenatal booking (where known) reported by :

21% of women with severe maternal morbidity from 2009 – 2012

20.4% of women giving birth in Scotland between 2009 - 2012

However, Women < 20 years of age with severe maternal morbidity were significantly more likely to smoke and come from the most deprived quintile

DEPRIVATION

DEPRIVATION QUINTILE OF WOMEN WITH SEVERE

MATERNAL MORBIDITY AND OF ALL WOMEN GIVING

BIRTH IN SCOTLAND 2009-2012

• Obesity increases the risk of severe maternal morbidity

• Smoking does not appear to influence severe maternal morbidity

• Women in the most and least deprived quintiles are those most likely to experience severe maternal morbidity.

• Further work to assess the impact of maternal age and deprivation on severe maternal morbidity is required
