There is increasing consensus that the effects of extreme weather conditions in the form of drought, flooding and extreme temperature will have increasingly devastating impacts on those who depend on climate‐sensitive resources and ecosystems for their livelihoods. The most affected will be the poor in developing countries who have a low adaptive capacity to climate change due to high poverty levels. Despite these projections, there are, to date, insufficient empirical studies linking the relationship between climate change and migration, particularly in the context of southern Africa. Using field‐based data collected from two study locations in Zambia, this paper examines the complex relationship between extreme weather events and population movement. It is envisaged that the findings presented in this paper will contribute to current discussions on the complex relationship between extreme weather conditions and population movement specifically in the context of sub‐Saharan Africa and other developing countries. 相似文献

Introduction: Injuries at work may negatively influence mental health due to lost or reduced working hours and financial burden of treatment. Our objective was to investigate, in U.S. workers (a) the prevalence of serious psychological distress (SPD) by injury status (occupational, non-occupational, and no injury) and injury characteristics, and (b) the association between injury status and SPD. Methods: Self-reported injuries within the previous three months were collected annually for 225,331 U.S. workers in the National Health Interview Survey (2004–2016). Psychological distress during the past 30 days was assessed using the Kessler 6 (K6) questions with Likert-type scale (0–4, total score range: 0–24). SPD was defined as K6 ≥ 13. Prevalence ratios (PR) from fitted logistic regression models were used to assess relationships between injury and SPD after controlling for covariates. Results: The prevalence of SPD was 4.74%, 3.58%, and 1.56% in workers reporting occupational injury (OI), non-occupational injury (NOI), and no injury, respectively. Workers with head and neck injury had the highest prevalence of SPD (Prevalence: OI = 7.71%, NOI = 6.17%), followed by workers with scrape/bruise/burn/bite (6.32% for those with OI). Workers reporting OI were two times more likely to have SPD compared to those without injury (PR = 2.19, 95%CI: 1.62–2.96). However, there was no significant difference in SPD between workers with OI and workers with NOI (PR = 0.98, 95%CI: 0.65–1.48). Conclusion: The prevalence of SPD varied by injury status with the highest being among workers reporting OI. We found that the workers reporting OI were significantly more likely to have SPD than those without injury, but not more than those with NOI. Practical Applications: Mental health management programs by employers are necessary for workers who are injured in the workplace. 相似文献

The main purpose of this study was to ascertain whether occupational exposure to asphalt fumes, under normal working conditions, is associated with any hepatotoxic, nephrotoxic, or hematotoxic response. This was a cross-sectional study in which 210 subjects (80 exposed and 130 reference subjects) were investigated. Using standard methods, atmospheric concentrations of total particulate and benzene-soluble fractions of asphalt fumes were measured. Additionally, urine and blood samples were taken from subjects for complete blood count, white blood cell differential test, urinalysis, and routine biochemical tests of kidney and liver function. Both groups were similar as far as their demographic variables and smoking habits were concerned. The levels of exposure to total particulate and benzene-soluble fractions were estimated to be 0.9?±?0.2 and 0.32?±?0.09 mg m?3, respectively (mean?±?SD), both of which being lower than the existing threshold limit values. Statistically, significant associations between exposure to asphalt fumes and changes in most liver and kidney function tests and complete blood count parameters provided circumstantial evidence in favor of the notion that exposure to sub-threshold limit value levels of total particulate and benzene-soluble fractions is associated with early liver and kidney dysfunction as well as hematological disorders. 相似文献

作业场所职业危害监管监察力量配备研究 总被引:3,自引:3,他引:0
职业危害形势严峻与监管力量相对匮乏的矛盾,是我国当前职业危害监管需要解决的问题之一。但是,实现作业场所职业危害的有效监管,应当配备多少数量的监管人员,一直以来缺乏系统的研究论证。本文根据国务院经济普查数据,以及国家统计局公布的有关工业企业的数据,初步探讨了分级监管模式下作业场所职业危害监管力量的配备情况,认为实现作业场所职业危害的有效分级监管,万名工人监管人员数至少达到1.34较为适宜,根据我国当前的工业企业从业人员数,全国范围内宜配备至少18590名职业卫生监管人员。 相似文献

Chronic low-level exposure to synthetic pesticides is implicated in many health conditions that result from the induction of oxidative stress, including cytogenetic damage. The objective of this study was to assess the risk of genotoxicity using micronuclei (MN) formation in lymphocytes and to determine changes in blood antioxidants superoxide dismutase (SOD) in erythrocytes (E) and glutathione (GSH) in E and plasma (PL) in farm workers for six months during a growing season. Blood and urine samples were collected once a month for six months (June to November 2003) from farm workers (n = 15) and urban unexposed controls (n = 10). Lymphocytes from blood were separated by density gradient centrifugation using Histopaque and cultured using the standard technique. There was no significant difference in the cytokinesis blocked proliferation index (CBPI) of lymphocytes between the farm workers and the control group, but there was a 76% increase in average MN frequency in lymphocytes of the farm worker group (P ≤ 0.05). In addition, MN frequency peaked during August as compared to the other months and the controls (P ≤ 0.05). An 18% decline was observed in the activity of E-SOD in the farm worker group (P ≤ 0.05). GSH in E and PL were similar in both groups. These data suggest that the farm workers may be at a greater risk of developing genotoxicity due to continued exposure to pesticides, especially during the intensive growing season. 相似文献

Background
All employees in health care settings handling needles or other sharps are at risk for needle stick and sharps injuries (NSSIs). Health care workers in under developed countries are at greater risk of infection from blood borne pathogens because of the lack of safety devices and the high prevalence of these pathogens.Objectives
The aim of this study was to assess the prevalence of NSSIs and associated factors among health care workers in government health institutions in Gondar city, Ethiopia.Methods
Institution based cross sectional study was conducted from May-December, 2010. The study included 344 health care workers who were selected from the source population using simple random sampling technique. Data were collected through interviews using structured and pre-tested questionnaire and the collected data were entered and analyzed using SPSS version 16.0.Results
The prevalence of NSSIs among health care workers in the preceding 12 months was 106 (30.8%), of which 58 (54.7%) was reported by females. Lack of training on occupational health and safety, working more than 48 h/week, dissatisfaction with work environment and work culture, greater than 10 years of work experience and having low and moderate perception of risk were found to be significantly associated with NSSIs.Conclusion
The study found high prevalence of NSSIs among health care workers. Effective training, ongoing awareness on the risk of hazards, preventive measures such as engineering control, and post-exposure prophylaxis following NSSIs are essential to reduce the risk of such injuries. 相似文献107.

This paper analyses the role of local social, cultural, and political institutions in post‐disaster reconstruction projects. It contends that such institutions are important considerations within community‐driven reconstruction initiatives, but are often viewed with ambivalence by external aid organisations. This paper draws upon in‐depth qualitative interviews with aid workers involved in the post‐tsunami reconstruction in Aceh, Indonesia, to establish: (i) what roles community institutions were suited to play in the reconstruction; (ii) what were the limitations of community institutions when engaging with external aid agencies; (iii) how did external aid agencies engage with local community institutions; and (iv) how did external aid agencies perceive community institutions. 相似文献

中国农民工最新情况调查报告 总被引:9,自引:0,他引:9
《国务院关于解决农民工问题的若干意见》实施1年以来,农民工的状况得到有效的改善。特别是工资收入有了明显的提高,月均工资比2004年增加625元,拖欠问题有所缓解,政府给农民工提供的服务有所加强。但是农民工收入低、处境困难等基本问题还没有得到根本改变,尤其是农民工比较强烈的市民化愿望也远远没有实现。所以必须在进一步落实各项解决农民工问题的政策的同时,还需要进行制度创新,加大相关投入,逐步消除农民工市民化的制度障碍和资金困难,从根本上解决农民工问题。 相似文献

One of the dimensions treated as part of a company’s safety culture or climate is workers’ attitudes towards risk and safety. In the present study these personal aspects are defined as workers’ safety culture, which is understood as a way of acting focused on life and taking care of one’s health. A questionnaire on safety culture was filled out by 200 employees of a metallurgical enterprise. Factor analysis was used to determine empirical scales of the questionnaire, whereas variance analysis was used to test hypotheses. The results confirmed the hypotheses that people who experienced accidents, dangerous situations, and—to a lesser extent—health problems had a lower level of safety culture. Nevertheless not all of the scales determined during factor analysis turned out to be significant as far as all kinds of those undesirable situations are concerned. Proposals for future studies are formulated in the conclusion. 相似文献
