The housing environment of participants in the Avon Longitudinal Study of Parents and Children (ALSPAC): a resource for studies of influences on health

Abstract

Background: Early life environmental health exposures related to housing can have a significant impact on an individual’s physical and mental health and physical development. Housing exposures can fall into two main areas – a representation of social circumstances and physical conditions.   Methods: During pregnancy and post-delivery, self-completion questionnaires concerning the housing environment were administered until the study offspring were aged 18 to the ALSPAC (Avon Longitudinal Study of Parents & Children) study mothers and their partners. Data collected included types of housing, housing tenure, numbers of rooms in the home, whether shared or sole use of kitchen and indoor flushing toilet, household moves, Council Tax band, difficulties in affording rent/mortgage and becoming homeless. Here we also describe the historic development of housing in the Bristol and surrounding Avon areas.   Results: Data collected included the tenure (e.g., owned/rented) of the home, its size (indexed by the number of rooms), the presence of over-crowding (measured by the number of residents per room), presence of amenities, and frequency of household moves. This information was collected on over 13,000 women during pregnancy >8000 at age 10 and >4000 at 18 years. Council Tax bands were asked at 10 and 18 years.   Conclusions: This is the first of two Data Notes on the housing type and housing circumstances of the families enrolled in ALSPAC. A second Data Note will detail their internal housing conditions. The data provides an excellent resource for researchers when considering the influences of housing on physical and mental health and development.
