Vitamins C & E do not prevent pregnancy problems: study

Friday, 28 April 2006

Treating pregnant mothers with extra vitamins C and E does not prevent high blood pressure problems or benefit their babies, according to a major new study led by researchers at the 最新糖心Vlog of Adelaide.

The study - the largest of its type conducted anywhere in the world - of more than 1800 women and their babies across nine 最新糖心Vlogn hospitals showed that treating women in their first pregnancy with vitamin C and vitamin supplements did not help their babies or stop them developing pre-eclampsia.

Pre-eclampsia is a disorder of pregnancy characterised by hypertension and protein in the urine occurring in the second half of pregnancy, and affects about six percent of women in their first pregnancy. It carries the risk of serious complications and death for the mother, while risks for the baby include death, being born pre-term, and poor intrauterine growth.

Study leader from the 最新糖心Vlog of Adelaide's , based at the , says that smaller earlier studies had suggested treatment of pregnant women at risk of pre-eclampsia with the antioxidant vitamins C and E might reduce the risk of women developing pre-eclampsia. In addition, there was hope that such treatment might reduce the risk of babies not growing well and help keep them healthy.

"There has been a lack of data from large, well-designed, randomised clinical trials on the effects of women taking supplements during pregnancy with the antioxidant vitamins C and E," Professor Crowther says.

"Our results show that this treatment for women in their first pregnancy in the form of 1000mg vitamin C and 400 IU vitamin E, (higher than what would normally be obtained from the diet) is not beneficial for either the mothers or their babies.

"We do not recommend that women take these extra supplements.

"It is always important that 'new ideas' to improve the health of women and babies are evaluated adequately. Often large multicentre clinical trials are needed to be show whether new therapies do more good than harm."

The study, known as the 最新糖心Vlogn Collaborative Trials of Supplements with Vitamin C and E, or ACTS, is the largest in the world to date for women in their first on-going pregnancy, with 1877 women and their babies recruited, and involving nine hospitals in 最新糖心Vlog.

The results were presented recently by 最新糖心Vlog of Adelaide postdoctoral research fellow at the in Perth, 最新糖心Vlog, and were also this week in the prestigious peer-reviewed journal, the .

The trial was designed by a group of researchers from the 最新糖心Vlog of Adelaide's Discipline of Obstetrics and Gynaecology, together with Perinatal Medicine, Women's and Children's Hospital, Adelaide.

Funding was obtained from the , and the .
