目的 了解大学生故意自伤行为和自杀行为的发生情况,并分析其相关性.方法 整群选取某医科大学4063名一、二年级在校生为研究对象,采用x2检验比较不同性别大学生故意自伤行为、自杀行为检出率差异,建立多因素logistic回归模型拟合多种研究变量对故意自伤行为-自杀行为的影响.结果 4063名大学生最近1年故意自伤行为检出率为13.4%,其中单次自伤检出率为3.7%,多次自伤检出率为9.6%,男生高于女生;最近1年自杀意念、自杀计划、自杀未遂和自杀行为的检出率分别为4.5%、1.4%、0 6%和4.9%,性别间差异无统计学意义(P>0.05).采用多元logistic回归分析,以有自伤无自杀组为参考,有自伤有自杀组表现为积极应对程度低(OR=0.5,95%CI:0.3 ~ 0.8)、伙伴个数相对较少(3~5个vs.≤2个:OR=0.6,95%CI:0.3 ~0.9;≥6个vs.≤2个:OR=0.4,95%CI:0.2~0.8);消极应对(OR=2.1,95%CI:1.2 ~ 3.7)、抑郁症状(OR=2.9,95%CI:1.6 ~ 5.2)、焦虑症状(OR=2.2,95%CI:1,2 ~ 3.8)、睡眠问题(OR=1.7,95%CI:1.1~2.8)、自评体型偏胖(偏胖vs.正常:OR=2.0,95%CI:1.1~3.6)较为常见.logistic回归分析发现,大学生故意自伤行为者中自杀行为的发生风险显著增加(OR=4.7,95%CI:3.5~6.4),而抑郁、应对方式、自评体型等社会心理因素会减弱两者的关联程度(OR=3.3,95%CI:2.4 ~ 4.5).自杀行为发生的风险随自伤次数的增加而增加(OR=3.1 ~ 10.0),社会心理因素也会减弱两者的关联(OR=2.4~5.9).结论 自伤行为虽然不是个体自杀行为发生的信号,但有必要在自伤者中开展自杀行为发生可能性的评估.  相似文献

目的分析探讨社会心理因素对妇产科医务人员工作相关肌肉骨骼疾患(WMSDs)的影响,以降低社会心理负荷,促进职业健康。方法选取某市各级医院的妇产科医务人员679人为研究对象,主要为妇科、产科医生以及助产士,采用自主研发的肌肉骨骼问卷调查其肌肉骨骼疾患状况,并进行横断面研究,对可能的危险因素进行多元Logistic回归分析。结果 3个因素影响妇产科医务人员的WMSDs:自觉身体健康状况差,自觉竭尽全力,单一工作姿势。自觉身体健康状况差的WMSDs患病风险是自觉身体健康状况良好的11.063倍(OR=11.063,95%CI=2.680~45.666,P=0.001);自觉竭尽全力(OR=2.762,95%CI=1.285~5.935,P=0.009)和单一工作姿势(OR=1.862,95%CI=1.174~2.953,P=0.008)是WMSDs不可忽视的危险因素。结论社会心理因素对妇产科医务人员的WMSDs有一定程度的影响,从社会心理因素出发研究相关的预防改善措施具有重要意义。  相似文献

Epidemiological studies of calcium and osteoporosis have been hampered by the lack of a suitable tool for assessing calcium intake. This report describes a new frequency and amount questionnaire for measuring present and past calcium intake in the elderly. The validity of the questionnaire was tested against two commonly used standards of dietary assessment, five-day duplicate diets and seven-day weighed dietary inventories. The resulting correlation coefficients were, respectively, r = 0.76 and r = 0.69, while that for repeatability was r = 0.84. Furthermore, the questionnaire categorized subjects into thirds of the distribution of intake with almost no gross misclassification. It is suggested that the present findings may be extended to the majority of normal, healthy elderly subjects, implying wide application for the questionnaire in the assessment of calcium intake in the elderly.  相似文献

Unemployment is considered to be a public health concern sincedeterioration in the health of the unemployed is often anticipated.However, for some groups, such as miners, unemployment mightimprove health due to a cessation of potentially harmful occupationalexposures. This study evaluates the health of 79 miners in oneSwedish iron-ore mine, and 226 age-matched controls from thegeneral population, during one year after the closure of themine. The participants received a questionnaire regarding medicalhistory and subjective symptoms at the beginning of the studyperiod, and after one year. Statistically significant negativeeffects on self-reported health attributable to unemploymentwere not found, although neuropsychiatric symptoms were morecommon among the unemployed miners. The miners reported a statisticallysignificant improvement in grip force (p=0.031). They had asignificantly higher prevalence of symptoms associated withmining related exposures when compared with the population controls;pain in the upper extremities [relative risk (RR)=2.27, 95%confidence interval (Cl)=1.44–3.59), back pain (RR=1.84;Cl=1.237–2.75), vasospastic disease of the fingers (RR=2.05;Cl=1.18–3.57) and obstructive respiratory symptoms (attacksof dyspnea and wheezing: RR=3.67; Cl=1.167–11.6).  相似文献

Context

Tularemia is a zoonosis affecting humans and hares in France. We describe the results of surveillance in both species, in 2007 and 2008.

Methods

Human tularemia cases are mandatorily notifiable in France since 2003. In hares, surveillance relies on volunteer hunter associations in all districts of the country. Data from mandatory reports and volunteer surveillance in 2007/2008 were analyzed and compared with previous results.

Results

In 2007/2008, 144 cases were reported in humans and 117 cases in hares. This was a 100% increase compared to previous years. Human cases differed from those of previous years only by the frequency of contact with breeding animals. Human cases without any documented risk exposure were also more frequent.

Conclusion

An increase of tularemia cases occurred in 2007/2008 in both species. Complementary studies are needed to identify the species reservoir in France to understand the causes of this peak of cases.  相似文献

Occupational health hazards in mining: an overview   总被引:1,自引:0,他引:1  
This review article outlines the physical, chemical, biological, ergonomic and psychosocial occupational health hazards of mining and associated metallurgical processes. Mining remains an important industrial sector in many parts of the world and although substantial progress has been made in the control of occupational health hazards, there remains room for further risk reduction. This applies particularly to traumatic injury hazards, ergonomic hazards and noise. Vigilance is also required to ensure exposures to coal dust and crystalline silica remain effectively controlled.  相似文献

This paper provides an overview of the production and use of nanomaterials (NMs), particularly in the UK. Currently, relatively few companies in the UK are identifiable as NM manufacturers, the main emphasis being the bulk markets in metals and metal oxides, and some niche markets such as carbon nanotubes and quantum dots. NM manufacturing in the UK does not reflect the global emphasis on fullerenes, nanotubes and fibres. Some assumptions have been made about the types of NM that are likely to be imported into the UK, which currently include fullerenes, modified fullerenes and other carbon-based NMs including nanotubes. Many university departments, spin-offs and private companies have developed processes for the manufacture of NMs but may only be producing small quantities for research and development (R&D) purposes. However, some have the potential to scale up to produce large quantities. The nanotechnology industry in the UK has strong R&D backup from universities and related institutions. This review has covered R&D trends at such institutions, and appropriate information has been added to a searchable database. While several companies are including NMs in their products, only a few (e.g. manufacturers of paints, coatings, cosmetics, catalysts, polymer composites) are using nanoparticles (NPs) in any significant quantities. However, this situation is likely to change rapidly. There is a need to collect more information about exposure to NPs in both manufacturing and user scenarios. As the market grows, and as manufacturers switch from the micro- to the nanoscale, the potential for exposure will increase. More research is required to quantify any risks to workers and consumers.  相似文献

Red cell membranes, prepared from red blood cells of rats exposed to 4, 10, or 20 ppm nitrogen dioxide (NO2) for 1 to 10 days, were examined for evidence of changes in membrane components. Appreciable changes were not found in contents of phospholipid and cholesterol during exposure to 10 ppm NO2. By contrast, protein content altered with the time of exposure. Moreover, changes in protein composition were observed by employing sodium dodecyl sulfate — polyacrylamide gel electrophoresis. Twenty-four-hour exposure to NO2 at the concentration above 10 ppm resulted in a marked increase in the percentage of lysophosphatidylethanolamine (LysoPE) to the total phospholipids. The prolonged exposure to 10 ppm NO2 gave rise to a further increase in LysoPE, whereas the percentage of phosphatidylethanolamine (PE) showed a gradual decrease. A 1-day exposure to 4.0 ppm NO2 also caused an increase in sialic acid content and decreases in those of PE and hexose. In addition to contents of these components the percentage of LysoPE increased 5 days after exposure and the elevated values were maintained up to the end of exposure period. These results demonstrate that red blood cells in circulation exhibit different membrane properties in terms of lipid and carbohydrate composition during 10 days of exposure to 4.0 ppm NO2.  相似文献

Clusters of disease are common and occur in the workplace and in the general community. They often arouse considerable concern among the population. Investigations have sometimes lead to exciting new knowledge, but in general the investigation of clusters is difficult and often unrewarding, especially for community clusters. In the workplace, investigations are more likely to find associations and even new causes, but still many clusters remain enigmatic. Despite this, there are many reasons for investigating clusters, including allaying community concern and identifying uncontrolled exposures. A structure for investigating clusters in the workplace is suggested.  相似文献
