Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, what proportion of pregnancies result in a diagnosis of post-natal depression.

We are advised by the Health and Social Care Information Centre that data is not collected on the diagnosis of post-natal depression.

The NHS Improving Quality report; Improving Access to Perinatal Mental Health Services in England – A review (published September 2015), says that post-natal depression prevalence within the first few post-natal months is estimated to be 13%. This suggests that following the 687,346 maternities in 2014 in England and Wales, there were around 90,000 women in 2014 who suffered from post-natal depression in the first few post-natal months.
