Depression of either parent linked to premature birth
Depression of either parent linked to premature birth
Depression in both expectant mothers and fathers increases the risk of premature birth, found a new study.

Depression in women during pregnancy is known to be associated with low birth weight and increased risk of premature birth. Maternal stress has also been shown to increase the risk of premature birth. However, little research has examined the impact of paternal depression on the health of the mother or the unborn child, Daily Mail‎ wrote.

In this study, more than 350,000 births in Sweden between 2007 and 2012 were investigated for parental depression and incidences of either very preterm birth (between 22 and 31 weeks) or moderately preterm birth (32-36 weeks).

For both men and women, depression was defined as having had a prescription of antidepressant medication, or receiving outpatient/inpatient hospital care, from 12 months before conception to the end of the second trimester of pregnancy. People with depression were classed as new cases if they had had no depression in the 12 months prior to diagnosis, all other cases were defined as recurrent depression.

While both new and recurrent depression in the mothers was associated with an increased risk of moderately preterm birth of around 30-40 percent, new depression in the fathers was associated with a 38-percent increased risk of very preterm birth. Recurrent depression in the fathers was not associated with preterm birth at all.

Professor Anders Hjern, from the Center for Health Equity Studies in Stockholm (CHESS), said, "Depression of a partner can be considered to be a substantial source of stress for an expectant mother, and this may result in the increased risk of very preterm birth seen in our study. Paternal depression is also known to affect sperm quality, have epigenetic effects on the DNA of the baby, and can also affect placenta function. However, this risk seems to be reduced for recurrent paternal depression, indicating that perhaps treatment for the depression reduces the risk of preterm birth.

"For the mothers, depression increased the risk of preterm birth, regardless of whether the depression was new or recurrent.

"Our results suggest that both maternal and paternal depression should be considered in preterm birth prevention strategies and both parents should be screened for mental health problems. Since men are less likely to seek professional help for any mental health problems, a proactive approach towards targeting the wellbeing of expectant fathers may be beneficial."

John Thorp, BJOG deputy editor-in-chief, added, “This study highlights the importance of treating depression for both men and women, and the impact untreated depression can have on the health of offspring.”
