Supplementary Information

ALSPAC attempted to make contact with eligible women through media information encouraging study contact and recruitment staff visiting community locations. In parallel, routine antenatal and maternity health services were used to promote the study and distribute an ‘expression of interest’ card. Through returning this card, women were able to request further information on the study or to decline participation. Completed cards contained sufficient detail to allow ALSPAC staff to determine eligibility.

Posters were printed for display in a variety of different places - including chemist shops, libraries, mother and toddler groups, and pre-school playgroups, general practitioner waiting-rooms, antenatal clinics and any other area where a mother in early pregnancy was likely to be. In addition, there was considerable local and national coverage in the press, radio and television.
