What is the prevalence of intra uterine growth retardation in Finland?

== Definition ==

=== Data ===

Intra uterine growth retardation is a clinical diagnosis for foetuses whose growth is restricted in the womb. The diagnosis can be made antenatally, as well as post partum. Partly due to inconsistencies in clinical monitoring and partly due to misinterpretation, IUGR is commonly also defined in the same way as small for gestational age (SGA). For example: "IUGR has a prevalence of 10% for all pregnancies. However, the figure varies in different patient populations, with rates of 3-5% for healthy mothers and 25% or higher for some high-risk groups, such as hypertensive mothers."[1] While a high proportion of SGA babies (based on post partum measurements relative to standardised curves of foetal growth (adjusted for age and ethnicity)) are IUGR, this is not the case for all of them. Some may simply be the children of small parents or parents of an ethnic group for which standardised growth curves have not been employed (i.e. they are genetically predisposed to being smaller). IUGR prevalence figures for the population of Finland are not currently available. For these reasons (and reasons touched upon here), the estimate of IUGR prevalence has been based on the definition of SGA with some variability, to account both for the lack of accurate standardisation of growth curves (i.e. variability within the population owing to ethnicity, for example) and for inherent misclassification. <ref>THL 2008: Births and newborns 2008.
