Mortality Study of the Population Ezposed to Chrysotile Asbestos
Objective To investigate the causes of death of the population exposed to chrysotile asbestos. Methods A mortality study on the causes of death was conducted. 2854 decedents of six towns in 2005-2006 were selected. According to the standard survey questionnaire, the issues of occupational history, disease history, smoking history and drinking behavior of decedents were investigated. The causes of death were categorized according to International Categories of Disease (ICD-10). The standardized proportionate mortality ratio (SPMR), and their corresponding 95% confidence intervals (CI) were calculated based on the age-standardized mortality ratios of local total population. Results The SPMR among female in middle-dose group was 1.44(CI 1.12-1.83) for death from respiratory diseases (68 deaths observed). The SPMR among female in high-dose group was 1.64(CI 1.27-2.09) for death from respiratory diseases (66 deaths observed) and 1.49(CI 1.04-2.07) for death due to lung cancers (35 deaths observed). Conclusions The results indicated that the excess of respiratory diseases and lung cancer among female were likely related to manual spinning of chrysotile asbestos operation. A further period of observation is required to monitor the mortality of the people exposed to chrysotile asbestos.
