Project Background:

This MRC-PHE centre study lead by Kings College London aims to describe and understand the patterns of exposure of the population in London to traffic pollution (including air and noise) and their relationships to health. The consortium of over 20 investigators has a wide range of work packages. SAHSU related deliverables are to quantify relationships between traffic noise and air pollution and the following health outcomes: mortality, hospital admissions and adverse birth outcomes including low birth weight in the study period 2003-10.

Study Aims:

Air pollution data comes from the Environmental Research Group at Kings College and noise exposures have been modelled at Imperial.  Health outcome data comes from HES maternity, ONS (and NN4B) birth records and ONS mortality records. Address- and postcode-level records are used in order to accurately estimate exposures at residential address.  We also propose (subject to appropriate permissions in place) to link HES maternity and ONS/NN4B birth records to provide ONS birth records with gestation weeks which is important for accurate exposure estimation and outcome interpretation.

Health data:

NHS Digital HES maternity, ONS births, ONS mortality, ONS NN4B

Benefits to Public:

The results of this study will allow for better understanding of the health problems caused by air pollution and noise from traffic in London. Any findings are likely to have a high media-profile and have the potential to influence air pollution policy and regulatory practices in London and the UK.  Output from this work will be disseminated via peer reviewed publication and academic conferences presentations.  The outputs of the project will be published in peer-reviewed journals during the course of the study and after completion, which is expected by 2016.
