Effects of drug administration in pregnancy on children's school behaviour.

Files with prescription data were used to assess possible behavioural changes in children, whose mothers used benzodiazepines or neuroleptic drugs during the second half of their pregnancy. Prescriptions, bearing the identification number of women resident in one district of Prague, filed in pharmacies during 1974 and the first three months of 1975 represent the first part of the data.

For economical analysis of consumption of cardiovascular drugs, three methodological approaches (expenditure figures, material units--number of packages and DDD (Defined Daily Dosis), as a technical unit of measurement) were chosen.
