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.

Footprints of children in Bangkok.

A total of 4,371 children, 2,220 boys and 2,151 girls, age ranging from one month to 18 years, in Bangkok were studied during 1985-1986. The studies of footprints included age, sex, height and weight. The footprint was measured the length of a tip of big toe to sole. It was found that the footprint was correlated with age (r = 0.91), height (r = 0.97) weight (r = 0.86). During the infancy period the growth of footprint was fast corresponded to height, weight, then gradually increase, and showed a spurt during puberty period prior to height and weight spurt. The footprint could predict the age, height and weight. The average male and female adult footprint was 26 and 23 cm respectively, which was double the average footprint at the age of 1 year 6 months in boys and 1 year 2 months in girls. The measurements of footprints may be valuable in predicting other parameters in anthropometry.
