From JAMA Network Open: “In this cohort study involving 38, 219 mother-child pairs, maternal physical activity before and during pregnancy was associated with neurodevelopmental outcomes in late infancy. Moreover, higher levels of maternal exercise were associated with more favorable neurodevelopmental outcomes.
…Among the 38 ,219 mother-child pairs (maternal mean [SD] age, 31.1 [4.8] years; 19 429 [50.8%] male children), multivariable logistic regression showed that higher maternal physical activity was associated with child neurodevelopment. Higher prepregnancy activity was associated with significantly higher odds for each ASQ-3 domain at 6 months of age and higher midpregnancy activity with high odds for the gross motor (odds ratio [OR], 1.18; 95% CI, 1.06-1.33), fine motor (OR, 1.60; 95% CI, 1.37-1.86), and problem solving (OR, 1.23; 95% CI, 1.10-1.38) domains. Higher prepregnancy activity was associated with higher odds for the problem-solving domain (OR, 1.16; 95% CI, 1.01-1.34) at 3 years of age; there was no association with any other domain. Higher midpregnancy activity was not associated with higher odds of any ASQ domain at 3 years of age.“
