    The aim of ALSPAC is to determine which biological, environmental, social, psychological and psychosocial factors are associated with the survival and optimal health and development of the fetus, infant and child, and the ways in which causal relationships might vary with the genetic composition of mother and/or child.

    To identify the complex ways in which environmental features may be associated with the optimal development, health and well-being of the child, will involve a study of the ways in which genes and the environment interact. A child's ability to meet environmental and social challenges is influenced by genetic variation, but the interactions are complex. Genetic susceptibility or resistance to common disorders is likely to be bestowed by one or more genetic polymorphisms, the impact of which will change as various environmental and developmental stresses on the child change. ALSPAC was specifically designed to analyse this interplay between genes and environment with respect to important relatively common health outcomes.

    20,800 DNA samples at present [Nov 2007] consist of approx 10,000 mothers, 10,000 children and 800 fathers. The latter are from buccal cells. Ultimately, the aim is to get DNA from as many of the participants as possible. Lymphocytes are gradually being transformed to generate cell lines (again on as many as possible).
