Secular trend of growth in pre-school children in Singapore.

An anthropometric study was conducted on more than 13 500 children aged 04 years in 1988. Percentile charts were plotted for height for age, weight for age, weight for height and head circumference for age. When compared to an earlier study done in 1972, it was found that Singapore pre-school children had increased in height by 4.4 %; weight by 10.9 %; and head circumference by 4.1 %. When the median height for age, weight for age and head circumference for age were plotted against those of the NCHS charts (1978), Singapore's pre-school children were generally shorter, lighter and had smaller head circumferences than their American counterparts of the same age. But, the median weight-for-height for each age group was comparable to the Americans. The results indicate the secular trend of growth in Singapore children and a trend towards reaching their full genetic potential for growth.
