Intrauterine growth and postnatal skeletal development: findings from the Southampton Women's Survey
Intrauterine growth and postnatal skeletal development: findings from the Southampton Women's Survey
We have previously demonstrated associations between fetal growth in late pregnancy
and postnatal bone mass. However, the relationships between the intrauterine and
early postnatal skeletal growth trajectory remain unknown. We addressed this in a
large population-based mother–offspring cohort study.A total of 628 mother–offspring
pairs were recruited from the SouthamptonWomen’s Survey. Fetal abdominal circumference
was measured at 11, 19 and 34 weeks gestation using high-resolution ultrasound
with femur length assessed at 19 and 34 weeks. Bone mineral content was
measured postnatally in the offspring using dual-energy X-ray absorptiometry at birth
and 4 years; postnatal linear growth was assessed at birth, 6, 12, 24, 36 and 48 months.
Late pregnancy abdominal circumference growth (19–34 weeks) was strongly (P < 0.01)
related to bone mass at birth, but less robustly associated with bone mass at 4 years.
Early pregnancy growth (11–19 weeks) was more strongly related to bone mass at 4
years than at birth. Postnatal relationships between growth and skeletal indices at 4
years were stronger for the first and second postnatal years, than the period aged 2–4
years. The proportion of children changing their place in the distribution of growth
velocities progressively reduced with each year of postnatal life. The late intrauterine
growth trajectory is a better predictor of skeletal growth and mineralisation at birth,
while the early intrauterine growth trajectory is a more powerful determinant of
skeletal status at age 4 years. The perturbations in this trajectory which influence
childhood bone mass warrant further research.

Abstract
We have previously demonstrated associations between fetal growth in late pregnancy
and postnatal bone mass. However, the relationships between the intrauterine and
early postnatal skeletal growth trajectory remain unknown. We addressed this in a
large population-based mother–offspring cohort study.A total of 628 mother–offspring
pairs were recruited from the SouthamptonWomen’s Survey. Fetal abdominal circumference
was measured at 11, 19 and 34 weeks gestation using high-resolution ultrasound
with femur length assessed at 19 and 34 weeks. Bone mineral content was
measured postnatally in the offspring using dual-energy X-ray absorptiometry at birth
and 4 years; postnatal linear growth was assessed at birth, 6, 12, 24, 36 and 48 months.
Late pregnancy abdominal circumference growth (19–34 weeks) was strongly (P < 0.01)
related to bone mass at birth, but less robustly associated with bone mass at 4 years.
Early pregnancy growth (11–19 weeks) was more strongly related to bone mass at 4
years than at birth. Postnatal relationships between growth and skeletal indices at 4
years were stronger for the first and second postnatal years, than the period aged 2–4
years. The proportion of children changing their place in the distribution of growth
velocities progressively reduced with each year of postnatal life. The late intrauterine
growth trajectory is a better predictor of skeletal growth and mineralisation at birth,
while the early intrauterine growth trajectory is a more powerful determinant of
skeletal status at age 4 years. The perturbations in this trajectory which influence
childhood bone mass warrant further research.
