Abstract:
Aim: Few studies have reported on early life risk factors for motor development outcomes past childhood.
Antenatal, perinatal and neonatal factors affecting motor development from late childhood to adolescence were explored.
As sex differences in motor development have been previously reported, males and females were examined separately.
Methods: Participants (n = 2868) were from the Western Australian Pregnancy Cohort Study.
Obstetric and neonatal data were examined to determine factors related to motor development at 10 (n = 1622), 14 (n = 1584) and 17 (n = 1221) years.
The Neuromuscular Development Index (NDI) of the McCarron Assessment of Motor Development determined offspring motor proficiency.
Linear mixed models were developed to allow for changes in motor development over time.
Results: Maternal pre-eclampsia, Caesarean section and low income were negatively related to male and female motor outcomes.
Lower percentage of optimal birthweight was related to a lower male NDI.
Younger maternal age, smoking during early pregnancy and stress during later pregnancy were related to lower female NDIs.
Conclusion: Events experienced during pregnancy were related to motor development into late adolescence.
Males and females were influenced differently by antenatal and perinatal risk factors; this may be due to sex-specific developmental pathways.
