Obese and underweight mums-to-be ‘at risk of problems during pregnancy’
Washington: Obese women run the risk of problems during pregnancy, labour and complications for the baby’s health, a new study has claimed.
A new study of more than 3000 expectant mothers confirms this, and also reveals that being underweight also has specific complications.
Researchers at University Hospital Virgen de las Nieves, in Granada, have identified the risks in pregnancy related specifically to obesity and have compared them to underweight women to confirm that extreme slimness also carries a risk.
“During pregnancy, obesity is linked to hypertension, gestational diabetes, premature labour, macrosomy of the foetus and unexplained death during labour,” Sebastian Manzanares, first author of the study, said.
“Nonetheless, there is still little data about the link between being underweight and perinatal complications,” he said.
The study includes a sample of 3,016 pregnant women, 168 (5.5 percent with extreme slimness, 2,597 (86.1 percent) with a normal weight and 251 (8.3 percent) being seriously or morbidly obese.
The results show that obese mothers have a higher risk of developing hypertension, diabetes mellitus, and colonization with group B streptococcus.
Also in these women it is more common to induce labour or undergo a caesarean section, whether elective or emergency. It is also more common for macrosomy or acidosis to occur at birth, or for the baby to die before it is born.
Furthermore, underweight women are more prone to oligohydramnios (reduction in the amount of amniotic liquid) and for their newborns to be underweight. The incidence of women going into labour prematurely or late did not differ significantly in relation to the mother``s weight.
“Severely or morbidly obese mothers have a higher risk of adverse results and perinatal mortality, and therefore should be advised about weight loss and how to recognise the early warning signs of possible complications.
“Nonetheless, this group, as well as underweight women, should be considered ‘high risk’,” he said.
The study has been published in the Journal of Maternal-Fetal and Neonatal Medicine.
