Synopsis

The PIAMA project's Natural History study: data collection from parents of two-year-oldsncidence of Asthma and Mite Allergy (PIAMA) project. PIAMA is a birth cohort study aimed at investigating prevention, incidence and risk factors pertaining to asthma and inhalation allergy. Recruitment of pregnant women for the PIAMA study took place between March 1996 and September 1997. The participating children (n=3291) in the Natural History study were born between July 1996 and October 1997. They will be followed until they are eight years old. Reported here is the collection of data on the children when they had reached the age of two. The data collection procedure and response to the questionnaire are described in detail. Results are summarised in tabular form. Of the original 3291 participants 128 (3.8%) were lost-to-follow-up before the age of two years. Questionnaires were therefore sent to 3167 parents and completed by 3053 (96.4%). Data collected covered potential risk factors in aspects of lifestyle and environment, such as nutrition, passive smoking, housing conditions, traffic near the home, use of day care and respiratory infections, as well as early signs and symptoms of allergy and asthma.
