Modelling the spatial distribution of teenage conception rates within Wessex.

This study attempts to determine which factors account for the spatial variation in teenage conception rates within the former Wessex Regional Health Authority and what factors account for the eventual outcomes of these conceptions. Postcoded data on all teenage conceptions from 1991 to 1994 were collected and related to census ward level information and indicators of accessibility to family planning services. The results show that the variation in teenage conception rates and conception outcomes is principally determined by the age of the teenager, deprivation levels, the presence of certain homogeneously distinct groups and the distance to the nearest youth-oriented family planning clinic.
