Insights
Developmental Coordination Disorder (DCD) affects 11.3% of children born very preterm at age 11, impacting cognition and quality of life. Despite challenges, their health-related quality of life exceeds general population norms.
Area of Science:
- Pediatrics
- Neurodevelopmental Disorders
- Child Psychology
Background:
- Children born very preterm face higher risks for neurodevelopmental challenges.
- Developmental Coordination Disorder (DCD) is a common motor disorder affecting children's daily lives.
- Understanding DCD's impact on cognition and quality of life in this population is crucial.
Purpose of the Study:
- To determine the prevalence of DCD in children born very preterm at 11 years of age.
- To investigate the correlation between DCD, cognitive function, and self-experienced health-related quality of life (HRQoL).
- To compare the HRQoL of very preterm children with DCD to their peers and population norms.
Main Methods:
- A prospective follow-up study of 170 children born very preterm in Finland.
- Motor skills assessed using Movement Assessment Battery for Children - Second Edition (Movement ABC-2).
- Cognitive abilities evaluated with Wechsler Intelligence Scale for Children - Fourth Edition (WISC-IV); HRQoL measured by the 17-Dimensional Illustrated Questionnaire (17D).
Main Results:
- 11.3% of very preterm children were diagnosed with DCD (Movement ABC-2 score ≤5th percentile).
- DCD correlated with poorer cognitive scores (Full-Scale IQ 76.8 vs 91.6, p=0.001) and lower self-reported HRQoL (17D 0.93 vs 0.96, p=0.03).
- Despite lower HRQoL compared to peers without motor impairment, very preterm children reported better HRQoL than Finnish population norms (p<0.001).
Conclusions:
- DCD remains prevalent at age 11 in children born very preterm.
- DCD is associated with impaired cognitive development and reduced health-related quality of life.
- Very preterm children, even with DCD, demonstrate a higher HRQoL compared to the general population.
Objective:
To evaluate the rate of developmental coordination disorder (DCD) and its correlation to cognition and self-experienced health-related quality of life (HRQoL) in children born very preterm.
Design:
Prospective follow-up study.
Setting:
Regional population of children born very preterm in Turku University Hospital, Finland, in 2001-2006.
Patients:
A total of 170 children born very preterm were followed up until 11 years of age.
Main Outcome Measures:
Motor and cognitive outcomes were evaluated using the Movement Assessment Battery for Children - Second Edition (Movement ABC-2) and the Wechsler Intelligence Scale for Children - Fourth Edition, respectively, and HRQoL using the 17-Dimensional Illustrated Questionnaire (17D). The Touwen neurological examination was performed to exclude other neurological conditions affecting the motor outcome.
Results:
Eighteen children born very preterm (17 boys) (11.3%) had DCD, defined as Movement ABC-2 total test score ≤5th percentile. A positive correlation between motor and cognitive outcome (r=0.22, p=0.006) was found. Children born very preterm with DCD had lower cognitive scores than those without DCD (Full-Scale IQ mean 76.8 vs 91.6, p=0.001). Moreover, children born very preterm with DCD reported lower HRQoL than children born very preterm without motor impairment (17D mean 0.93 vs 0.96, p=0.03). However, HRQoL was higher in this group of children born very preterm compared with population-based normative test results (p<0.001).
Conclusions:
DCD was still common at 11 years of age in children born very preterm in 2000s. DCD associated with adverse cognitive development and lower self-experienced HRQoL. However, this group of children born very preterm reported better HRQoL in comparison with Finnish norms.
