Prenatal lifestyle interventions found to improve child neurodevelopmental outcomes

Maternal structured lifestyle interventions during pregnancy based on a Mediterranean diet or mindfulness-based stress reduction (MBSR) improve child neurodevelopmental outcomes at age 2 years, according to a study published online on Aug. 22 in JAMA Network Open.

Francesca Crovetto, M.D., Ph.D., from the University of Barcelona in Spain, and colleagues examined whether structured interventions based on a Mediterranean diet or MBSR during pregnancy improve child neurodevelopment at age 2 years in a prespecified analysis of a parallel-group randomized clinical trial.

A total of 1,221 singleton pregnancies with a high risk for developing newborns who were small for gestational age were randomly assigned to a Mediterranean diet intervention, including educational sessions and free provision of extra virgin olive oil and walnuts; an MBSR program adapted for pregnancy; or usual care per institutional protocols.

Neurodevelopment was assessed in 626 children at a mean age of 24.8 months. The researchers found that children in the Mediterranean diet group had higher scores in the cognitive and social-emotional domains than children from the usual care group (β, 5.02 and 5.15, respectively), while children from the stress reduction group had higher scores in the social-emotional domain (β, 4.75).

"These results need replication in further randomized clinical trials as well as assessment in additional patient populations," the authors write.
