The hypothesis that birth weight predicts blood pressure inversely at age 7 through 11 years was examined in 1,446 white children and black children in Washington Parish, Louisiana.
Two data sets of the Bogalusa Heart Study were merged : 1) newborn cohort participants (n=233), initially examined at birth, 1973-1974, and reexamined in 1984-1985 at ages 9 through 11 years ; and 2) subjects examined at ages 7 through 11 years in 1987-1988 (n=1,213) whose birth weight was collected from birth certificates in 1991.
The prevalence ratios for being in the race-sex-and age-specific upper decile of diastolic blood pressure in children born with low birth weight (<2,500 g) versus those with birth weight =2,500 g were 0.85 (95% confidence interval 0.28-2.56) for white boys, 2.66 (95% confidence interval 1.24-5.70, p<0.05) for black boys, 1.38 (95% confidence interval 0.63-3.03) for white girls, and 1.05 (95% confidence interval 0.40-2.75) for black girls.
For systolic blood pressure, the corresponding prevalence ratio for each race-sex group did not differ from one.
When the analyses were restricted to full-term births, prevalence ratios in any race-sex group did not differ from one for systolic and diastolic blood pressure.
In multiple linear regression analyses, the concurrently determined Quetelet index (p<0.001) was a much stronger correlate of systolic and diastolic blood pressure after appropriate adjustment than was birth weight (p>0.05). (...)
