The growth of low-birth-weight children
Insights
Children born with low birth weight (LBW) show significantly poorer growth compared to normal birth weight peers and their parents. LBW children were shorter than parents, indicating long-term growth deficits.
Area of Science:
- Pediatric Growth and Development
- Perinatal Medicine
- Anthropometry
Background:
- Low birth weight (LBW) is a critical indicator of infant health and can impact long-term development.
- Understanding the growth trajectory of LBW children is essential for identifying potential health disparities.
- Previous studies suggest potential growth deficits in LBW populations, but comprehensive anthropometric comparisons are needed.
Purpose of the Study:
- To compare the physical growth of seven-year-old children born with low birth weight (≤2000 g) against their parents and normal birth weight peers.
- To assess anthropometric parameters including height, weight, head circumference, skeletal diameters, and skinfold thickness in LBW children.
- To investigate the relationship between head circumference and intellectual ability in this cohort.
Main Methods:
- A cohort of 171 seven-year-old children, free from major disabilities, was studied.
- Measurements included: height, weight, occipitofrontal circumference, biparietal, occipitofrontal, and bi-iliac diameters, and triceps and subscapular skinfold thickness.
- Comparisons were made between low-birth-weight children, their parents, and a control group of normal-birth-weight children.
Main Results:
- Low-birth-weight children were significantly shorter than their parents, while normal birth weight children were taller than their parents.
- All measured anthropometric parameters, especially weight, were significantly lower in the low-birth-weight group compared to controls.
- No significant correlation was found between occipitofrontal circumference and intellectual ability in the studied children.
Conclusions:
- Children born with low birth weight exhibit persistent growth deficits by age seven, falling behind both their parents and normal birth weight peers.
- These findings highlight the long-term impact of LBW on physical development, emphasizing the need for continued monitoring and support.
- Occipitofrontal circumference does not appear to be a reliable indicator of intellectual ability in this LBW cohort.
Abstract:
The growth of 171 seven-year-old children, free from major disability, with a birth weight of 2000 g or less was examined and compared with that of their own parents and of normal-birth-weight peers. Measurements included height, weight, occipitofrontal circumference, biparietal, occipitofrontal and bi-iliac diameters, triceps and subscapular skinfold thickness. Low-birth-weight children were shorter than their parents whereas those of normal birth weight were taller. For all parameters, particularly weight, the low-birth-weight children were significantly less well grown. There was no significant relationship between occipitofrontal circumference and intellectual ability.
