Abstract
Objective: To investigate the effect of physical activity (PA) on development (motor, cognitive, social-emotional) in children 4-5 years old born <30 weeks' gestation, and to describe subgroups of children at risk of low PA in this cohort.
Design: Longitudinal cohort study.
Patients: 123 children born <30 weeks were recruited at birth and assessed between 4 and 5 years' corrected age.
Main outcome measures: Development was assessed using the Movement Assessment Battery for Children, Second Edition (MABC-2), Little Developmental Coordination Disorder Questionnaire (L-DCDQ), Wechsler Preschool and Primary Scale of Intelligence (Fourth Edition; WPPSI-IV), and Strengths and Difficulties Questionnaire (SDQ). To measure PA, children wore an accelerometer and parents completed a diary for 7 days. Effects of PA on developmental outcomes, and associations between perinatal risk factors and PA, were estimated using linear regression.
Results: More accelerometer-measured PA was associated with better MABC-2 aiming and catching scores (average standard score increase per hour increase in PA: 0.54, 95% CI 0.11, 0.96; p=0.013), and lower WPPSI-IV processing speed index scores (average composite score decrease per hour increase in PA: -2.36, 95% CI -4.19 to -0.53; p=0.012). Higher accelerometer-measured PA was associated with better SDQ prosocial scores. Major brain injury in the neonatal period was associated with less moderate-vigorous and less unstructured PA at 4-5 years.
Conclusions: Higher levels of PA are associated with aspects of motor, cognitive and social-emotional skill development in children 4-5 years old born <30 weeks. Those with major brain injury in the neonatal period may be more vulnerable to low PA at preschool age.
期刊介绍:
Archives of Disease in Childhood is an international peer review journal that aims to keep paediatricians and others up to date with advances in the diagnosis and treatment of childhood diseases as well as advocacy issues such as child protection. It focuses on all aspects of child health and disease from the perinatal period (in the Fetal and Neonatal edition) through to adolescence. ADC includes original research reports, commentaries, reviews of clinical and policy issues, and evidence reports. Areas covered include: community child health, public health, epidemiology, acute paediatrics, advocacy, and ethics.
