Size at birth and blood pressure : cross sectional study in 8-11 year old children.
To identify which patterns of fetal growth, represented by different measurements of size at birth, are associated with increased blood pressure in children aged 8-11 years.
Design and setting
School based, cross sectional survey conducted in 10 towns in England and Wales in 1994.
3010 singleton children (response rate 75%) with physical measurements and information on birth weight from parental questionnaires.
Hospital birth records were examined for 1573.
Main outcome measures
Systolic and diastolic blood pressure at age 8-11 years.
In the whole group birth weight was inversely related to systolic pressure (regression coefficient - 1.48 mm Hg/kg ; 95%) confidence interval - 2.20 to - 0.76) after adjustment for current body size.
There was no significant association between birth weight and diastolic pressure.
The association with systolic pressure was much stronger in girls (-2.54 mm Hg/kg ; - 3.60 to - 1.48) than in boys (-0.64 mm Hg/kg ; - 1.58 to 0.30), with a significant difference between the sexes (P=0.006).
Among the other neonatal measures, head circumference and placental weight were inversely associated with subsequent blood pressure in girls, and placental ratio (placental weight : birth weight) was positively associated with blood pressure in boys.
Neither ponderal index at birth nor length : head circumference ratio was related to blood pressure in either sex. (...)
