dc.description.abstractPneumonia is currently the major killer of children in the developing world, and air pollution has been implicated as one of the causes. Little research has been done in the area of third world urban air pollution and pneumonia. A pilot case-control study was conducted at the Children's Hospital in Bangkok Thailand, between February and July 1993, to examine the association between particulate levels in Bangkok homes and the risk of childhood pneumonia in the under 2 age group, to examine environmental sources of particulates, and also to explore other environmental and demographic risk factors for pneumonia. In this study 61 cases and 67 controls were enroled. Pneumonia cases came from two inpatient wards, and the controls came primarily from a well baby immunization clinic at the same hospital. Interviews were conducted in the hospital, and then cases and controls were visited at home for an environmental audit of their homes which included a 24 hour sample of inhalable particulates called 'PM10', a measure of the fine particulate matter most relevant to respiratory health. Univariate analyses and multivariate logistic regression were performed in order to obtain unadjusted and adjusted odds ratios (OR) and their confidence intervals (CI), used as a measure of strength of association between the various risk factors and pneumonia. The results of this study indicate a preliminary estimate of relative risk of pneumonia of at least 2.0 for children from homes with PM10 levels over 150 ug/m3 , adjusted for nutritional status, maternal education, childcare and ventilation. As expected, in this pilot study, this association was not significant (OR 2.06, CI 0.51- 8.40). Using PM10 as a continuous variable however, gives an almost statistically significant adjusted odds ratio of 3.27 (CI 0.96-11.18) for every 100 ug/m3 increment in PM10. From the univariate analysis, however there was no evidence of a dose response relationship. Almost 40% of the study population, were exposed to levels of PM10 over the U.S. EPA standard of 150 ug/m3 ...en
