Results indicate that the NCHS height-for-age reference values for children between 5 and 9 years of age are "attainable" by Sri Lankan children, except at centiles above the 75th. The NCHS weight-for-age reference value are well above the corresponding values for Sri Lankan children between 10 and 18 years of age.

Colombo, 1988) Godawatta, R.; Wickramanayake, T.W.The mean age at menarche (MAM) of girls attending two schools in the City of Colombo catering families of a high socio-economic-educational status has been compared with that of girls of lower socio-economic status in the city and in rural Kadawata. The MAM for the former group is 11.8 years, lower than values reported earlier for more mixed Sri Lankan populations. In all schools studied those who have reached menarche are significantly taller, heavier, have a higher BMI, mid-arm-circum ference and skinfold thickness than those who have not attained age. The man weight of girls who have reached menarche is above 40 kg in all age groups and BMI is above 17.0. The importance of the socio-economic, educational and nutritional status, from the time of birth to the adolescent spurt, to the early onset of menarche, is stressed.
