Population/study
information [6]
Children starting kindergarten in
1998-9 school year in over 1000 US
schools (Early Childhood
Longitudinal Study - Kindergarten
Class). 5 year follow up.
Adolescents 12-18yrs followed from

from the National Longitudinal Study of

Results [8] Using data adjusted for confounders,
birth weight was not associated with
a significant change in BMI from
either kindergarten to third grade (-
0.039 kg/m 2 , SE 0.021m, P=0.-63) or
kindergarten to fifth grade (-0.041
kg/m 2 , SE 0.030, P=0.177).
For males, birth weight (each 100 g
increase) is associated with an increased
prevalence of overweight adj OR 1.03,
(95% CI 1.00-1.07) in early adulthood.
There was no association in females.
BMI at age 17yrs was higher with birth
weight >4000 g 1.37 kg/m 2 (95% CI
0.22-2.53) P
