Pubertal linear growth of Indian girls adopted in Sweden.

Pubertal linear growth in 66 adopted Indian girls was studied. The infancy-childhood-puberty standard was used, since it is applicable to Indian girls, and enables determination of the onset and height gain of the pubertal growth phase in an individual. At arrival in Sweden, mean height was -2.8 SDS. Despite rapid catch-up growth, the girls were still below the reference mean (-0.8 SDS) at the onset of the pubertal growth spurt, which occurred approximately 1.5 years earlier than in Swedish girls and also earlier than in Indian girls. The pubertal height gain, however, was equivalent to that in Swedish girls with similar timing of puberty. The short final height found in some of these girls appears to be related to shortness prior to puberty and to very early onset of an otherwise normal pubertal growth component.
