The overall objective of this research project is to investigate the role of exposure to ambient airborne particulates in the development of adverse cardiovascular responses to identify possible mechanisms of action. These relationships will be investigated in a community cohort living in close proximity to a large Boston, MA, bus terminal. The specific objective of this research project is to examine cardiovascular changes in healthy individuals and individuals with predisposing risk factors such as chronic bronchitis, chronic obstructive pulmonary disease, and asthma. Serum fibrinogen and C-reactive protein levels also will be investigated in this group.
All equipment and supply orders were finalized and ordered. All necessary contracts with outside laboratories for Holter monitoring and blood and urine analyses were finalized. The informed consent and detailed questionnaire on occupational exposures, smoking history, respiratory and cardiac symptoms, and family history were finalized and translated into Portuguese and Spanish. The Access and Excel databases to compile this information were developed and finalized. Also, study personnel were trained.
Recruitment of study subjects from the North Dorchester-Roxbury, MA, neighborhoods began in October 2003, by obtaining a list of all eligible subjects, both healthy and compromised individuals. Compromised individuals were defined as those without asthma (adult onset, treated), chronic bronchitis, emphysema, chronic obstructive pulmonary disease, diabetes, and hypertension more than 18 years old and had been seen at the clinic within the last 6 months. Initial contact was made through an informational mailing, with followup recruitment made via telephone.
We will continue subject recruitment. All subjects will be asked to wear the Holter heart monitor in conjunction with the continuous PM2.5 monitor for a 24- to 48-hour period and have their blood drawn and urine collected. Subjects also will complete the detailed medical history, lifestyle questionnaire, and activity diary. All data obtained will be subjected to the outline quality control procedures and entered into the Access and Excel databases.
Preliminary data analyses will begin in the next reporting period.
