• Most 'unexplained' stillbirths were growth restricted    • Customised charts and appropriate protocols should be used   
• Most stillbirths with IUGR are avoidable    • Standardised FH measurement and referral improves detection      
• A/N detection improves outcome and reduces SB    • In high risk pregnancy, serial scans improve detection   

Effect on Stillbirth

A co-ordinated growth assessment programme has reduced ONS stillbirth rates in three English regions with high uptake (West Midlands, Yorkshire & The Humber, North East). For detailed analysis, see BMJ Open 2013 and J Public Health 2014

The reduction is mainly in stillbirths with IUGR                            The Times Leading Article

According to the latest (2019) ONS figures, stillbirth rates in England have fallen consistently for 8 years to 3.83/1000.

This represents a 28.4% reduction from the 2000-09 (10 year) average of 5.35, and equates to 1,005 babies saved per year.
