A case series of silicotics employed in the North Carolina dusty trades is presented. Working lifetimes quartz exposure summaries are estimated using both the simple cumulative, and weighted models. Linear regression techniques are applied to study the latency in disease development, using the time from first exposure to diagnosis as the dependent variable. In addition to quartz exposure, race, age at first exposure, smoking history and year of diagnosis, the magnitude of the peak quartz exposure and the timing of the peak exposure in the work history were found to be important independent variables. For the cumulative and weighted model exposure estimates the multiple correlation coefficient were approximately 0.44 (p < 0.0001) and (p < 0.0001), respectively. [ABSTRACT FROM PUBLISHER] |
