This national cohort study characterizes neurodevelopmental outcomes at age 6.5 years of children who had extreme preterm births (<27 weeks) in Sweden.
To examine the associations between active commuting to school and cognitive performance in adolescents.
Five cities (Granada, Madrid, Murcia, Santander, and Zaragoza) in Spain.
A total of 1700 adolescents (892 girls) aged 13 to 18.5 years.
Mode and duration of transportation to school and participation in extracurricular physical activity were self-reported.
Cognitive performance (verbal, numeric, and reasoning abilities and an overall score) was measured by the Spanish version of the SRA Test of Educational Ability.
Active commuting to school was associated with better cognitive performance (all P < .05) in girls but not in boys, independent of potential confounders including participation in extracurricular physical activity. In addition, adolescent girls who spent more than 15 minutes actively commuting to school had better scores in 3 of the 4 cognitive performance variables (all P < .05) than those who spent less time actively commuting to school (≤15 minutes) as well as better scores in all of the cognitive performance variables (all P < .001) than girls inactively commuting.
Active commuting to school and its duration may positively influence cognitive performance in adolescent girls.
Meador et al examined the effects of antiepileptic drug exposure via breastfeeding on cognitive functions at age 6 years among 181 children for whom both breastfeeding and IQ data were available. All mothers in this analysis continued taking drug after delivery. Differential Ability Scales IQ was the primary outcome. See the editorial by Harden.
This systematic review summarizes prognostic factors for poor cognitive development in children born very preterm or with very low birth weight.
To examine relationships of breastfeeding duration and exclusivity with child cognition at ages 3 and 7 years and to evaluate the extent to which maternal fish intake during lactation modifies associations of infant feeding with later cognition, Belfort et al followed up 312 Project Viva mothers and children to age 7 years. See the Editorial by Christakis.
This randomized clinical trial of the effectiveness of trauma-focused cognitive behavioral therapy for orphans and vulnerable children in Zambia found that the therapy decreased symptoms related to trauma and stress.
