  1. Infant mortality and soil type : a case study in south-central England. Discussion. Authors'reply.

    Article - En anglais

    We have analysed the differences in infant mortality for 1981 to 1990 in areas of contrasting soil types in south-central England.

    The soils overlie rocks of varied lithology and hydrology, ranging from porous and permeable Chalk and limestones, to the generally wet and impermeable Oxford and Lower Jurassic Clays.

    The study area comprises 504 administrative wards, for each of which the soil has been classified as being predominantly'Wet'Intermediate'or'Dry'depending on the degree of seasonal or periodic waterlogging.

    The soil classes used are those mapped by the Soil Survey of England and Wales and relate closely to the underlying geology.

    We find proportionately more infant deaths on the'Wet'soils, and a gradation towards lower infant mortality rates on the drier soils.

    Overall, infant mortality on the'Wet'soils is 31.9 percent greater than on the'Dry'soils, for reasons that remain unexplained.

    This relation between infant mortality and soil moisture remains after the effect of social class has been removed.
