Untreated prenatal depression can also carry risk of child behaviour problems

Researchers in Norway also found that untreated depression – without the use of prenatal antidepressants – is associated with behaviour problems in children.
The conclusions were met when scientists looked through data belonging to more than 20,000 pairs of siblings from the Norwegian Mother and Child Cohort study with babies and toddlers aged up to three.
Mothers’ mental health states were assessed with questions about symptoms of anxiety and depression while pregnant and six months after birth – including the use of prescribed medications – using a validated short version of the Hopkins Symptom Checklist.
They were also asked to report their lifetime history of major depression, which is characterised by sad moods, changes in appetite, loss of energy, feelings of guilt and worthlessness and problems concentrating for a period of more than two weeks.
More than 20 per cent of women suffer from depression in their child-bearing years, according to the study published in the International Journal of Epidemiology, and antidepressant prescriptions have doubled in the UK in the past 10 years.
This raises questions as to the level of impact antidepressants can have on the development of children, as the medication can travel through the placenta and unborn baby’s brain, and how behavioural traits can be influenced by mental states of parents.
Researchers claim that therapies and counselling sessions such as CBT, cognitive behavioural therapy, are more effective and safe than taking pills while expecting.
Smoking, drinking and drug use among pregnant women is more common in those who experience depression and anxiety and the study participants were questioned about whether they used alcohol and harmful substances during pregnancy.
Mothers were also asked to fill out the questionnaire about their child’s behaviour and emotional development at the ages of 18 months and 36 months.
Scientists found that anti-depressant use during pregnancy had clear connections to anxiety in young children. However, the use of medication was not related to emotional reactivity, somatic complaints, sleep problems, attention problems or aggression.
“At 36 months of age, the crude unmatched regression analyses showed significant associations between prenatal antidepressant exposure and internalizing behaviour,” the study states.
Comparing the differences between siblings is handy for scientists as they can easily assess the impact of genetic influence on their findings, says lead author and researcher Ragnhild Eek Brandlistuen.
Studying siblings also makes it easier to recognise and take into account the familial and environmental risk factors.
