  • Pregnant women with BMI of 35 or more twice as likely to lose child
  • Mothers from ethnic minorities more likely to have stillbirths or neonatal death

Numbers of deaths in newborn babies where the mother is obese are worryingly high, an expert said today.

Since 2000, stillbirth and neonatal mortality rates in the UK have shown a downward trend, according to the Perinatal Mortality 2009 report, published today by the Centre for Maternal and Child Enquiries.

However, 10 per cent of mothers who had a stillbirth or whose babies died in the neonatal period in 2009 had a BMI (Body Mass Index) of 35 or more, an indicator of obesity, the report found.

This is twice the UK rate (5 per cent) of all deliveries to women with a BMI of 35 or more at any point in pregnancy.

In addition, the report found links between stillbirths and neonatal deaths and age. Mothers who had stillbirths and neonatal deaths were more likely to be younger (less than 25 years old) and older (40 plus).

The youngest (less than 20 years old) mothers were 1.4 times more likely to have a stillbirth and 1.2 times more likely to have a neonatal death than mothers of 25-29.

The older (40 plus) were 1.7 and 1.3 times more likely to have a stillbirth or neonatal death respectively compared to mothers of 25-29.

Ethnicity was also a significant factor. Mothers from ethnic minority groups are more likely to have stillbirths and neonatal deaths, the report found.

Mothers of black ethnic origin were 2.1 times more likely to have a stillbirth and 2.4 times more likely to have a neonatal death than mothers of white ethnic origin.

Similarly, mothers of Asian ethnic origin were 1.6 times more likely to have a stillbirth or a neonatal death than mothers of white ethnic origin.

Dr Tony Falconer, president of the Royal College of Obstetricians and Gynaecologists, said: ‘Every stillbirth is a tragic event. This report highlights a promising downward trend of perinatal mortality over the last 10 years. However, worryingly, the numbers of perinatal deaths linked to rising obesity is high.

‘Maternal obesity is a key public health concern and pregnant women who are obese need to know about the possible risks to them and their baby. The ideal situation of course would be for women to maintain a healthy weight before they fall pregnant to ensure the best outcome for them and their babies. Therefore, it is vitally important for women to be encouraged to lead healthy lifestyles throughout their lives and they can get good information from their GPs on diet, nutrition and exercise.’

The stillbirth rate decreased from 5.4 per 1,000 total births in 2000, to 5.2 per 1,000 total births in 2009. The perinatal mortality rate showed a downward trend from 8.3 per 1,000 total births in 2000 to 7.6 per 1,000 total births in 2009 and the neonatal mortality rate decreased from 3.9 per 1,000 live births in 2000 to 3.2 per 1,000 live births in 2009.

A stillbirth is where a baby is delivered without signs of life after 23 to 29 weeks of pregnancy. A neonatal death is the death of a live born baby occurring before 28 completed days after birth. A perinatal death is the death of a foetus or newborn in the perinatal period, commencing at 24 completed weeks of gestation and ending before seven completed days after birth.

Royal College of Midwives general secretary Cathy Warwick said: ‘This is good news as the stillbirth rate has dropped marginally from 2000.

‘However, the effect of obesity, deprivation and ethnicity on maternal health outcomes continues and this emphasises the need to direct more resources to mothers in these groups in order to reduce the gap between best and worst outcomes during childbirth.

‘At a time when resources are tight, it is vital that care is both effective and efficient.
