Standards for height, weight and head circumference from one month to six years based on Stockholm children born in 1980

Growth data on height, weight and head circumference were collected from Stockholm children from one month to six years of age, born in 1980, and representing all socio-economic groups. The sample consisted of 2471 children (1264 boys and 1207 girls), most of whom were measured on 10–15 occasions. From these measurements centile standards were constructed using a statistical technique which separates between-individual and within-individual variation, since only the former is appropriate to distance standards. Compared to former Swedish standards the present heights and weights were similar up to 2.0 years of age but thereafter considerably greater. Head circumference was larger throughout, perhaps due to a difference in measurement technique.
