Selected AbstractsJob categories and acute ischemic heart disease: a hospital-based, case-control study in TaiwanAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 6 2007Jong-Dar Chen MD Abstract Background Most studies of the relationship between work and acute ischemic heart disease (IHD) were performed in western populations, and the extent to which their findings hold in Asian populations is largely unknown. The purpose of this study was to examine the association between job categories and non-fatal, first episodes of acute IHD in Taipei, Taiwan. Methods A hospital-based, case-control design was used. Cases were patients with a first episode of non-fatal acute IHD who were admitted to the department of cardiology. Two controls without known cardiovascular disease were matched to each case for age, gender, and date of admission. A total of 119 cases and 238 controls were enrolled between April and September 2004. Results Compared with white-collar workers, blue-collar workers had a 5.3-fold (95% CI: 1.5, 18.5) increased risk of a first episode of non-fatal acute IHD, while self-employed workers and managers/professionals had a slightly lower odds ratio of 0.6 (95% CI: 0.1, 2.4) and 0.5 (95% CI: 0.1, 2.2), respectively. Hypertension, diabetes, obesity, physical inactivity, and sleep disturbance were significant risk factors for acute IHD. A clustering of the cardiovascular risk factors was found in blue-collar workers. Conclusions Blue-collar workers had a 5.3-fold increased risk of a first event of non-fatal acute IHD compared with white-collar workers, and this increased risk was associated with a clustering of cardiovascular risk factors.

[source] Are immigrants, ethnic and linguistic minorities over-represented in jobs with a high level of compensated risk?AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 9 2010Canada study using census, Results from a montréal, workers' compensation data Abstract Objectives Few Canadian data sources allow the examination of disparities by ethnicity, language, or immigrant status in occupational exposures or health outcomes. However, it is possible to document the mechanisms that can create disparities, such as the over-representation of population groups in high-risk jobs. We evaluated, in the Montréal context, the relationship between the social composition of jobs and their associated risk level. Methods We used data from the 2001 Statistics Canada census and from Québec's workers' compensation board for 2000,2002 to characterize job categories defined as major industrial groups crossed with three professional categories (manual, mixed, non-manual). Immigrant, visible, and linguistic minority status variables were used to describe job composition. The frequency rate of compensated health problems and the average duration of compensation determined job risk level. The relationship between the social composition and risk level of jobs was evaluated with Kendall correlations. Results The proportion of immigrants and minorities was positively and significantly linked to the risk level across job categories. Many relationships were significant for women only. In analyses done within manual jobs, relationships with the frequency rate reversed and were significant, except for the relationship with the proportion of individuals with knowledge of French only, which remained positive. Conclusions Immigrants, visible, and linguistic minorities in Montréal are more likely to work where there is an increased level of compensated risk. Reversed relationships within manual jobs may be explained by under-reporting and under-compensation in vulnerable populations compared to those with knowledge of the province's majority language.

[source] Occupational exposure to methyl tertiary butyl ether in relation to key health symptom prevalence: the effect of measurement error correctionENVIRONMETRICS, Issue 6 2003Aparna P. Keshaviah Abstract In 1995, White et al. reported that methyl tertiary butyl ether (MTBE), an oxygenate added to gasoline, was significantly associated with key health symptoms, including headaches, eye irritation, and burning of the nose and throat, among 44 people occupationally exposed to the compound and for whom serum MTBE measurements were available (odds ratio (OR),=,8.9, 95% CI,=,[1.2, 75.6]). However, these serum MTBE measurements were available for only 29 per cent of the 150 subjects enrolled. Around the same time, Mannino et al. conducted a similar study among individuals occupationally exposed to low levels of MTBE and did not find a significant association between exposure to MTBE and the presence of one or more key health symptoms among the 264 study participants (OR,=,0.60, 95% CI,=,[0.3, 1.21]). In this article, we evaluate the effect of MTBE on the prevalence of key health symptoms by applying a regression calibration method to White et al.'s and Mannino et al.'s data. Unlike White et al., who classified exposure using actual MTBE levels among a subset of the participants, and Mannino et al., who classified exposure based on job category among all participants, we use all of the available data to obtain an estimate of the effect of MTBE in units of serum concentration, adjusted for measurement error due to using job category instead of measured exposure. After adjusting for age, gender and smoking status, MTBE exposure was found to be significantly associated with a 50 per cent increase in the prevalence of one or more key health symptoms per order of magnitude increase in blood concentration on the log10 scale, using data from the 409 study participants with complete information on the covariates (95% CI,=,[1.00, 2.25]). Simulation results indicated that under conditions similar to those observed in these data, the estimator is unbiased and has a coverage probability close to the nominal value. The methodology illustrated in this article is advantageous because all of the available data were used in the analysis, obtaining a more precise estimate of exposure effect on health outcome, and the estimate is adjusted for measurement error due to using job category instead of measured exposure.

[source] Does Gender Still Matter?GENDER, WORK & ORGANISATION, Issue 4 2007A Study of the Views of Women in the ICT Industry in New Zealand Using data from in-depth interviews with female information and communication technology (ICT) professionals from New Zealand's four main cities, this article uses a social constructivist framework to investigate the women's perceptions of their ICT work place. The results show that there are regional differences in organization type, job category and salaries, as well as in the perceptions of the women towards their environment. Most women did not actively seek to be employed in ICT , rather their entry was serendipitous. While they enjoyed working in the environment, there was an obvious gendering of the workforce with most technical positions being held by men and women working mainly in the softer side of ICT. The women perceived their gendered roles to be a highly important and an integral part of ICT and believed their salaries were equitable with their male colleagues. Having a greater understanding of how women view their ICT work place will contribute to attracting and retaining them in an industry where a shortage of skills is envisaged in the near future. [source] Attitude of hospital personnel faced with living liver donation in a Spanish center with a living donor liver transplant programLIVER TRANSPLANTATION, Issue 7 2007A. Ríos In Spain, despite its high rate of cadaveric donation, death while on the liver transplant waiting list is high. For this reason, living liver donation is being encouraged despite of the risk of morbidity for the donor. The objective of this study was to analyze attitudes toward living liver donation among hospital personnel in a hospital with a recently authorized living donor liver transplantation program. A random sample was taken and was stratified by type of service and job category (n = 1,262). Attitude was evaluated by means of a validated psychosocial questionnaire. The questionnaire was completed anonymously and was self-administered. Statistical analysis included the Student t test, the ,2 test, and logistical regression analysis. The questionnaire completion rate was 93% (n = 1,168). Only 15% (n = 170) of respondents were in favor of living liver donation if it were unrelated. An additional 65% (n = 766) were in favor if this donation, but only for relatives. Of the rest, 9% (n = 107) did not agree with living liver donation, and the remaining 11% (n = 125) were undecided. The variables related to this attitude were age (P = 0.044); job category (P = 0.002); type of service (according to whether it is related to organ donation and transplantation) (P = 0.044); participation in prosocial activities (P = 0.026); attitude toward cadaveric organ donation (P <0.001); attitude of a respondent's partner toward organ donation (P = 0.010); a respondent's belief that in the future, he or she may need a transplant (P < 0.001); and a willingness to receive a donated living liver organ if one were needed (P < 0.001). There is also a close relationship between attitude toward living kidney donation and living liver donation (P < 0.001). In the multivariate analysis, the only common independent variable from the bivariate analysis was a willingness to receive a living donor liver transplant if one were needed (odds ratio = 9.3). Attitude toward living liver donation among hospital personnel in a hospital with a solid organ transplant program is favorable and is affected by factors related to cadaveric donation, altruistic activity, and feelings of reciprocity. Physicians and the youngest hospital workers are those who are most in favor, which leads us to think that there is a promising future for living liver transplantation, which is essential given the cadaveric organ deficit and the high mortality rate while on the waiting list.

[source] Psychosocial work environment and medical symptoms among Swedish commercial airline cabin crewAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 7 2010Kurt Wahlstedt MD Abstract Background Associations between stress measured by the demands-control model, iso-strain model, and stress-related symptoms among cabin crew were studied. Methods A questionnaire about psychosocial work environment and symptoms was answered by 918 (82%) flight attendants, stewards, and pursers at one airline company in 2005. Adjustment was made for age, gender, smoking, job category, and flight length using multiple logistic regression. Results Weekly headaches, concentration difficulties, fatigue, and gastrointestinal symptoms were reported at rates of 18%, 10%, 56%, and 13%, respectively. Pursers scored higher on control than the others and they had lower associations between the strain measured by the demands-control model and symptoms than stewards and flight attendants. All symptoms were more common in the high strain situation than in the low strain (reference). An active situation was related to an excess of symptoms. Low social support in the iso-strain model increased risk of symptoms. Conclusions Demands-control and iso-strain models are useful in studying stress-related symptoms in cabin crews. The dimension of social support adds explanatory value. Am. J. Ind. Med. 53:716,723, 2010. © 2010 Wiley-Liss, Inc. [source] Urinary 1-hydroxypyrene concentrations in Chinese coke oven workers relative to job category, respirator usage, and cigarette smokingAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 9 2007Bo Chen PhD Abstract Background 1-Hydroxypyrene (1-OHP) is a biomarker of recent exposure to polycyclic aromatic hydrocarbons (PAHs). We investigated whether urinary 1-OHP concentrations in Chinese coke oven workers (COWs) are modulated by job category, respirator usage, and cigarette smoking. Methods The present cross-sectional study measured urinary 1-OHP concentrations in 197 COWs from Coking plant I and 250 COWs from Coking plant II, as well as 220 unexposed referents from Control plant I and 56 referents from Control plant II. Results Urinary 1-OHP concentrations (geometric mean, µmol/mol creatinine) were 5.18 and 4.21 in workers from Coking plants I and II, respectively. The highest 1-OHP levels in urine were found among topside workers including lidmen, tar chasers, and whistlers. Benchmen had higher 1-OHP levels than other workers at the sideoven. Above 75% of the COWs exceeded the recommended occupational exposure limit of 2.3 µmol/mol creatinine. Respirator usage and increased body mass index (BMI) slightly reduced 1-OHP levels in COWs (P,<,0.1). Cigarette smoking significantly increased urinary 1-OHP levels in unexposed referents (P,<,0.005), but had no effect in COWs (P,>,0.1). Conclusions Chinese COWs, especially topside workers and benchmen, are exposed to high levels of PAHs. Urinary 1-OHP concentrations appear to be modulated by respirator usage and BMI in COWs, as well as by smoking in unexposed referents. Am. J. Ind. Med. 50:657,663, 2007. © 2007 Wiley-Liss, Inc. [source] Primary health care personnel faced with cadaveric organ donation: a multicenter study in south-eastern SpainCLINICAL TRANSPLANTATION, Issue 5 2008A. Ríos Abstract:, Introduction:, Primary health care (PHC) is the first point of contact between the public and the health system and it is an important channel for the communication and promotion of organ donation and transplantation. The objective of this study was to analyze the attitude of PHC personnel toward donation and to determine the psychosocial variables affecting this attitude. Materials and methods:, A random sample was stratified by job category and geographical location among PHC personnel (n = 482) from 32 health centers. Attitude was evaluated using a questionnaire validated in our local area. (It was completed anonymously and was self-administered.) Results:, The questionnaire completion rate was 86% (n = 414): 78% (n = 325) are in favor and the remaining 22% (n = 89) are either against or are not sure. The reason given for a negative attitude is fear of apparent death (16%; n = 14). There are many independent factors that affect attitude: (i) job category (OR = 2.4); (ii) knowledge of the concept of brain death (OR = 2.2); (iii) a preference for alternatives to burial (OR = 2.99); (iv) being in favor of cremation (OR = 01.87) and (v) knowledge of the attitude of one's partner toward organ donation (OR = 0.312). Conclusion:, PHC personnel have a favorable attitude toward donation, especially physicians, although it would be useful to provide more information to PHC personnel. Physicians could be a key element in the direct and indirect promotion of donation and transplantation. [source] | ||||||||||
