Abstract

The authors conducted a cross-sectional study to evaluate the differences of screening test results between clerks and laborers in an occupational health center in Taegu, 1992. A total of 10,207 workers was included in the study of these, male were 5,597 and female 3,610. Constitutional variables included were items of health examination and some confounding variables(sex, age, body weight and work duration). All analyses were conducted separately for each sex through the use of multiple logistic regression analysis on occupation, controlling for age, work duration, and body weight. laborers showed abnormal hearing test more often than clerks in both sexes. The blood pressure that showed statistical significance in univariate analysis in both sexes lost its significance after controlling covariates. Liver function and urine protein had statistically significant differences between two occupational groups in males and visual correction did in females. The results suggest that there are differences clerks and laborers in some of screening tests and analytic studies are needed to identify the causes of the differences.
