RESUMO
Objective@#This study aims to validate a Filipino version of the questionnaire by Delclos et al on occupational risk factors and asthma among the health care workers of the Philippine General Hospital.@*Methodology@#Forward and backward translation method for bilinguals was used in this study. The Filipino translation was administered to 110 health care workers selected by stratified random sampling. After 24 hours, the retranslated English version was given to the same respondents. Testing for internal consistency reliability was done by computing for Cronbach's alpha. Construct validity was subsequently determined using the Cramer's V Coefficient.@*Results@#The Filipino questionnaire showed good internal consistency reliability, as shown by the overall Cronbach’s alpha of 0.9016, which is comparable to that of the original version by Delclos. Likewise, our Filipino questionnaire showed good construct validity, supported by the Cramer’s V coefficients ranging from 0.2204 (strong relationship) to 0.7843 (very strong relationship).@*Conclusion@#Overall, the Filipino version of the questionnaire for work-related asthma tested among the health care workers of Philippine General Hospital showed good reliability and validity. This may now be used as screening tool for occupational asthma among health care workers who are at risk of developing the disease. In addition, this research tool may be utilized to establish the prevalence of occupational asthma in hospitals and later on, aid in the development of a better working environment for the whole health care team.

PURPOSE: To determine the incidence and epidemiological characteristics of work-related asthma in Korea. METHODS: During 2004-2009, the Korea Work-Related Asthma Surveillance (KOWAS) program collected data on new cases of work-related asthma from occupational physicians, allergy and chest physicians, regional surveillance systems, and workers' compensation schemes. The incidence was calculated on the basis of industry, occupation, sex, age, and region. In addition, the distribution of causal agents was determined. RESULTS: During the study period, 236 cases of work-related asthma were reported, with 77 cases from more than 1 source. A total of 22.0% (n=52) were reported by occupational physicians, 52.5% (n=124) by allergy and chest physicians, 24.2% (n=57) by regional surveillance systems, and 43.2% (n=102) by workers' compensation schemes. The overall average annual incidence was 3.31 cases/million workers, with a rate of 3.78/million among men and 2.58/million among women. The highest incidence was observed in the 50-59-year age group (7.74/million), in the Gyeonggi/Incheon suburb of Seoul (8.50/million), in the furniture and other instrument manufacturing industries (67.62/million), and among craft and related trades workers (17.75/million). The most common causal agents were isocyanates (46.6%), flour/grain (8.5%), metal (5.9%), reactive dyes (5.1%), and solvents (4.2%). CONCLUSIONS: The incidence of work-related asthma in Korea was relatively low, and varied according to industry, occupation, gender, age, and region. Data provided by workers' compensation schemes and physician reports have been useful for determining the incidence and causes of work-related asthma.
