Abstract
Data from the Swedish Medical Birth Registration, 1977–1981 were used to apply methods of constructing reference standards for size at birth. Using clinical information a ‘healthy’ sub‐population was extracted. The conditional distributions of birthweight (BW) and birth‐length (BL) for each week of Gestational age, and the conditional distribution of birthweight given birthlength were modelled using truncated Normal distributions, after making use of Box‐Cox power transformations. Spline functions were then used in conjunction with a multiplicative method to obtain appropriate percentage point curves. Examples of this analysis are given.Keywords
