Obstetric data collected for 1966-cohort's children whose mothers were living permanently in the city of Oulu.
Prenatal information concerning mother's health condition during pregnancy was obtained from the antenatal cards requested from the antenatal clinics.
Delivery data was collected (1965-1967) by filling in a questionnaire in the maternity hospitals in Oulu by midfives. The forms were coded and saved to the punch cards by the researh secretary according to detailed instructions under the supervision of the researcher. The data were double-checked by punching the forms twice and after verifying differences between the two punchings the values were corrected to the data.
