Maternal hypertension linked to mental health issues in children
Maternal hypertensive disorders are caused by high blood pressure during pregnancy. These conditions include preeclampsia, eclampsia, gestational hypertension, and chronic hypertension.
Hypertensive pregnancy disorders are a leading cause of maternal mortality, and increase the risk of stillbirth and preterm birth.
A study focused on more than 4,700 mother-child pairs revealed that preeclampsia, in particular, was associated with an increased risk of behavioral and emotional disorders among children.
The researchers established a 66-percent higher risk of mental health issues among children whose mothers had preeclampsia.
The experts determined that the severity of maternal preeclampsia also played a role in the development of mental disorders during childhood.
“While previous studies have shown significant effects of preeclampsia on ADHD, autism spectrum disorder and schizophrenia in the offspring, a novel aspect of our findings was that the predisposing effects of maternal preeclampsia extended to any childhood mental disorder in the offspring,” said study senior author Dr. Marius Lahti-Pulkkinen.
The researchers found that when a maternal hypertensive disorder was combined with obesity and diabetes, the risk of the child developing a mental health disorder jumped from 6.6 to 22.2 percent.
“The findings emphasize the need for preventive interventions and treatments for maternal hypertensive disorders, since such interventions have the potential to benefit both the well-being of the expectant mother and her offspring,” said Dr. Lahti-Pulkkinen.
“The findings also shed important new light on the etiology of childhood mental disorders. This information may help in targeting preventive interventions and support for families at risk, and aid clinicians in understanding issues and the underlying causes of childhood mental disorders.”
The study is published in the journal Hypertension.
