Objectives-To determine the presence and magnitude of any relation between short term variations in ambient concentrations of particulate matter under 10 mum in diameter (PM10) and hospital admissions and mortality in Birmingham, United Kingdom.
To find the relative risk associated with various concentrations of PM10, and to estimate the potential public health benefit of reducing PM10 to below various thresholds.
Methods-Retrospective ecological study.
Air pollution data were taken from a national network monitoring station between 1 April 1992 and 31 March 1994, and weather data for the same period from the University of Birmingham Weather Service.
Daily total hospital admissions for the same period for asthma, bronchitis, pneumonia, chronic obstructive pulmonary disease (COPD), acute ischaemic heart disease, acute cerebrovascular disease, all respiratory conditions, and all circulatory conditions were obtained from the West Midlands Regional Health Authority, as well as daily total deaths from 1 April 1992 to 31 December 1994 for chronic obstructive pulmonary disease, pneumonia, all respiratory diseases, all circulatory diseases, and all causes.
Multiple linear regression models were constructed after adjusting for confounding factors (day of week, month, linear trend, relative humidity, and temperature). (...)
