The study was conducted from May to July in 1995 to investigate lifestyle variables associated with anemia in some female workers of the six large plants in Taegu. Cases were selected by a doctor based on symptoms and physical exmination and controls were matched according to age limits (?) and plant employed. The final subjects analyzed were 385 excluding. 36 who had underlying diseases associated with anemia or many missing values. Anemia was defined by the blood hemoglobin level less than 12 g/dL. Anemic subjects were 190(49.4%) with nonsignificant age distribution between cases and controls. Univariate logistic regression showed that there was no statistically significant difference in sociodemographic and occupational variables. Number of pad used during menstruation (odds ratio, OR=1.03, 95% Confidence interval ei,1.00-l-1.05) was the only significant among the menstruation-related variables. None of the lifestyle variables were significant but those who consume more than 4 cups of coffee a day vs. none and animal iron intake showed borderline statistical significance with the ORs 2.60 and 0.99, respectively. After controlling for marital status, native place and number of pad with the multiple logistic regression, those who consume more than 4 cups of coffee a day vs. none showed statistically significant OR 2.93(95% CI 1.01-8.49). Animal iron intake and diet to lose weight indicated borderline significance with ORs 0.99(p=0.06) and 1.47(p=0.09), respectively. These results suggest that there are some anemia-associated lifestyle variables and these variables may be important for the behavior modification to prevent anemia in female workers.
