Height and weight of school children and adolescent girls and boys in Oslo 1970.

Height and weight measurements of the school children of Oslo in 1970 (aged 7 to 19 years) are reported. Weights show considerably skewed distributions with long tails towards higher weights. Weight precentiles are calculated by interpolation in the empirical distributions. Percentiles and tables for both sexes, showing height for age, weight for height and weight for age, are presented. A comparison with existing Norwegian data from Sundal, 1956, Bergen shows that the application of statistics based on normal distribution for weight, has introduced considerable error in these percentiles. Oslo children in 1970 are taller by 5-6 cm at age eighteen, than USA (Iowa) standards and 4-5 cm taller compared to Tanner-s English percentiles. Oslo children are also taller than Swedish children, and have reached a stature higher than found in any other comparable study.
