Maternal Stress and Overweight Girls

The number of children with overweight or obesity—especially among kids younger than 6—is rising in modern societies. Being overweight before preschool increases the likelihood that children will develop obesity as they grow older.

Researchers from the Helmholtz Centre for Environ┬¡mental Research in Leipzig, Germany, conducted a longitudinal analysis of data on 498 mother–child pairs, from pregnancy through birth and on through each child’s first 5 years. Each pair’s data included the child’s biometrics and the mother’s perceived and actual stressors during pregnancy and the child’s first 2 years.

Data analysis showed a strong association between mothers’ perceived stress levels and the development of childhood overweight in girls. The association was true only for females. Study authors recommended finding ways of reducing mental stress in mothers to help lower childhood obesity risks.

These findings support encouraging women to participate in physical activity programs during pregnancy, since exercise training is beneficial and safe, and it reduces maternal stress during prenatal and postpartum periods.
