Relationship between selected health problems and exposures among women semiconductor workers in Malaysia

A study conducted between 1998-2001 on the semiconductor industry in Penang and Selangor found that irregular menstruation, dysmenorrhea and stress were identified as the three leading health problems by women workers from a checklist of 16 health problems. After adjusting for confounding factors, including age, working duration in current factory, and marital status, in a multiple logistic regression model, wafer polishing workers were found to experience significantly higher odds of experiencing irregular menstruation. Dysmenorrhea was found to be significantly associated with chemical usage and poor ventilation, while stress was found to be related to poor ventilation, noise and low temperatures.
