The growth of children whose parents originated from the Indian sub-continent (Asians) was compared with that of indigenous, white children in Rochdale (Caucasians) in a longitudinal study during the first 2 years of life. Reference was made to growth standards currently used in the UK and a small cross-sectional growth study was also carried out on related infants living in Pakistan. With the exception of birthweight, analysis of variance revealed few significant differences in individual growth parameters between the two populations living in the UK.
