Social adversity doubles the chance of low birth weight

2 June 2011

Women who have experienced three or more stressful life events or social health issues during pregnancy have double the chance of having a baby with a low birth weight, according to a study by Murdoch Childrens.

The study surveyed over 4,000 mothers and asked questions about women's views and experiences of antenatal care, stressful life events and social health issues in the 12 months prior to the birth, and maternal and infant health outcomes.

Two thirds of women in the study reported one or more stressful life events or social health issues during pregnancy, and 17 per cent reported three or more issues.

The study found those who had experienced three or more stressful life events or social health issues were more likely to have their first pregnancy check-up later in pregnancy, and to attend fewer antenatal visits.

Infants that are born preterm or with a low birth weight have increased health risks in childhood, and a greater risk of developing chronic disease later in life.

The recommendations from the study include implementation of targeted preventive strategies in antenatal care to ensure antenatal care services respond effectively to social health issues affecting maternal, newborn and child health.
