Height and weight of Thai children: high socioeconomic group of the some selected urban population.

A total of 4,371 high socioeconomic children, 2,220 boys and 2,151 girls, from Bangkok Metropolis, from 1985 to 1986 was studied. The height and weight were computed according to sex and age, height and weight for age, and weight for height were calculated in different percentiles (P5, P25, P50, P75 and P95). It was found that height and weight for age of a selected population of children are generally higher, they are taller and heavier than the children of previous studies. At 18 years of age, the average boy is 171 cm and 58 kg, while the average girls is 157.5 cm and 47 kg. The growth rate of Thai adults should be better with socioeconomic improvement in the standards of living in the future. Weight for height is not different from the previous studies, this is a more reliable and better parameter to evaluate the growth of children.
