Study suggests better air quality led to improved lung function in California children

January 23, 2017

Research Report 190 describes a study by Frank Gilliland and colleagues that was funded under HEI's Accountability research program. The investigators collected air quality data and lung function and respiratory symptom measures in three cohorts of children who participated in the Children’s Health Study in Southern California. During the 20-year study period, nearly 20 major policy actions were implemented to reduce pollution from transportation and other sources. Gilliland and colleagues evaluated whether the improved air quality was associated with improved lung function and respiratory symptoms in these children.

This unpublished research report describes a two-year study aimed at building and testing a method for the semi-continuous measurement of reactive oxidant species (ROS) generated by particulate matter in a cellular assay. The assay relied on the use of a compound that turns into a fluorescent product upon reaction with ROS generated in the cells.

This newsletter reports on the approval of new HEI studies to examine potential health effects of low-level pollution; the completion of a review of diesel exhaust studies (Special Report 19) by an HEI-appointed panel; and WHO's plans to update global air quality guidelines. In addition, it announces the publication of an HEI report taking a closer look at exposure to PM2.5 and its composition and a report evaluating rapid heart rhythm changes after exposure to PM. HEI also announces the recipient of the 2015 Walter A. Rosenblith New Investigator Award and the appointment of three new HEI Research Committee members.

Research Report 171

October 2012

This report describes the first-ever multicity study to estimate the effect of short-term exposures to particulate matter (PM10) and to ozone on mortality in nine Latin American cities. Led by Dr. Isabelle Romieu in Mexico, in collaboration with Dr. Nelson Gouveia in Brazil and Dr. Luis Cifuentes in Chile, the researchers evaluated mortality from all causes and in different age groups, using a common analytic framework. They analyzed mortality in each city and the region as a whole, and explored two pollutant models in individual cities. They also used two meta-analytic statistical techniques to further analyze the effects from individual cities.
