Sensitivity of perceptuomotor measures for very low birthweight (VLBW < or = 1500 g) pre-schoolers
1Department of Management and Social Science, Queen Margaret College, Edinburgh, UK.
Insights
Very low birthweight (VLBW) preschoolers showed developmental differences compared to normal birthweight peers. VLBW children had poorer fine motor skills and lower IQ scores by 36 months.
Area of Science:
- Pediatrics
- Developmental Psychology
- Neuroscience
Background:
- Very low birthweight (VLBW) is associated with potential developmental challenges.
- Longitudinal data is crucial for understanding developmental trajectories in VLBW infants.
- Identifying specific areas of difference can inform early interventions.
Purpose of the Study:
- To compare cognitive and perceptuomotor development in VLBW preschoolers without major handicaps to matched normal birthweight controls.
- To identify developmental differences at key preschool ages (24, 30, 36 months).
Main Methods:
- Longitudinal study design.
- Inclusion of VLBW (< or = 1500 g) and normal birthweight preschool children.
- Matching of groups by gender, ethnicity, birth order, social class, and maternal age.
- Assessment of cognitive and perceptuomotor skills at 24, 30, and 36 months.
Main Results:
- Statistically significant developmental differences were observed between VLBW and control groups at 24, 30, and 36 months.
- The VLBW group consistently demonstrated less optimal fine motor skills across all test ages.
- By 36 months, VLBW children scored lower on IQ tests compared to controls.
Conclusions:
- VLBW children, even without major handicaps, exhibit distinct developmental patterns in early childhood.
- Fine motor skills and cognitive abilities (IQ) are particularly affected by VLBW status.
- The findings highlight the sensitivity of developmental measures in detecting subtle differences in VLBW populations.
Abstract:
This longitudinal study investigated whether very low birthweight (VLBW < or = 1500 g) pre-schoolers with no major handicap differed in cognitive and perceptuomotor development from a control group of normal birthweight children, matched for gender, ethnic origin, birth order, social class and maternal age. There were statistically significant differences between the groups at 24, 30 and 36 months. At all test ages, the VLBW group showed less optimal fine motor skills, and at 36 months, obtained lower IQ scores. The implications of the developmental differences and the sensitivity of the measures are discussed.
