端视ICP—AES法测定尿中Pb,Mn,Cd,As,Se,Cr,Be,Ni,Cu,Zn等微量元素

尿中Ｐｂ、Ｍｎ、Ｃｄ、Ａｓ、Ｓｅ、Ｃｒ、Ｂｅ、Ｎｉ、Ｃｕ、Ｚｎ等微量元素是反应职业接触水平的重要指标,其准确测定为职业病防治、急慢性中毒诊断等提供科学依据。已建立的方法有化学比色法〔２〕、原子吸收法〔２、７、１１〕、示波极谱法〔２〕、荧光分光光度法〔２〕、气相色谱法〔２〕、阳极溶出伏安法〔２〕等,但这些方法大部分具有操作复杂、灵敏度低、消耗试剂多、分析周期长、可能接触有毒有害试剂等缺点。ＩＣＰ－ＡＥＳ法测定尿中多种元素,国内外文献已有报道〔１、３－６、８－１０、１２〕。但传统的ＩＣＰ－ＡＥＳ法检…     

Alt, krank, arbeitslos, chancenlos?

Illness can be the cause and consequence of unemployment. These relationships are well documented but only few data on the effectiveness of interventions are available. The study examines the effectiveness of a combined health and employment promotion intervention (AmigA - currently projected in several sites in Germany) for the older long-term unemployed with the main goals of an improvement of health and integrability as well as sustainable reintegration into the labour market. The evaluation design is a randomised controlled trial with a multi-method approach. A total of 71 participants could be included in the evaluation. Initial results confirm earlier findings on health and unemployment and show a psychologically and physically highly burdened sample. The intervention tended to improve depression, self-efficacy and quality of life. No effects were found for physical health, integrability and sustainable reintegration. It is discussed whether a longer duration and a higher intensity of the intervention might produce better results. The necessity of help and interventions for this highly burdened group of persons is evident but further studies are necessary to decide if the evaluated intervention is adequate to reach the goals of health and employment promotion as a standard measure.     

Europe and hospitals--strengths and requirements

Hospitals all over Europe must get ready to face the important challenge of 1993 at all levels: micro-economic, macro-economic, local, regional and European. Despite the liberalization trends which will inevitably appear with the increased freedom of exchange and movement, hospitals must strive to remain havens of peace to patients.     

企业职工高尿酸血症与血压、血脂、血糖的相关性研究

目的探讨企业职工高尿酸血症（HUA）与血压、血脂、血糖的相关性,为企业进行健康管理提供依据。方法以中国石油长庆油田公司各下属企业为抽样单位,整群随机抽取2个单位,每个单位中所有的HUA者作为HUA组,共720人;同时在尿酸水平正常者中随机选取620人为正常组。通过Logistic回归分析HUA与年龄、性别、血压、血脂、血糖的关系。结果HUA合并高血压、高血脂、空腹m糖受损任意一项、两项、三项的比例均远高于正常组（OR值分别为：4．036,2．562,4．174）。多因素Logistic回归发现：男性、收缩压、总胆固醇、三酰甘油、低密度脂蛋白胆固醇是HUA的危险因素（OR值分别为7．736,2．309,1．721,2．761,1．411）;高密度脂蛋白胆固醇为HUA的保护因素（OR值为0．211）。结论HUA存在性别差异,且与血压、血脂密切相关。企业对职工的健康管理应充分考虑多危险因素的综合作用,全面的进行健康教育及干预。     

Self-Esteem and Fruit and Vegetable Intake in Women and Men

Influences on food choices are multifactorial, and limited research has been reported on the role of social-psychological variables. Earlier studies have linked self-esteem with a variety of health behaviors. The purpose of this study was to extend the research to examine the relationship of self-esteem to dietary behaviors, specifically the intake of fruits and vegetables and their key nutrients. Subjects were 155 married couples in a stratified random sample of households in one mid-western state. Husbands and wives were interviewed separately in their own homes. Independent variables were age, education, income, body mass index, and self-esteem.The dependent variables were number of servings and variety of vegetables and fruits per week and energy-adjusted intakes of fiber, folate, and vitamins A and C. Self-esteem was measured by the Rosenberg questionnaire, while dietary intake was assessed by a semiquantitative food frequency questionnaire. Women reported significantly more servings of fruits per week, greater variety in both fruit and vegetable choices, and higher energy-adjusted nutrient intakes than did their husbands. Women met Food Guide Pyramid (FGP) recommendations for fruit intake and approached the recommendation for vegetable servings. Men fell short of FGP recommendations for both fruit and vegetables. After adjustment for age, education, income, and body mass index, self-esteem was a significant predictor of vitamin C and folate intake among women and folate intake among men. No other dietary variables were associated with self-esteem, although for men there was a trend for increased weekly servings of vegetables and increased variety in vegetable choices with higher self-esteem. One implication for practice is that age and education appear to be far stronger factors contributing to fruit and vegetable intake than is self-esteem. Additional research is needed to clarify the strength of self-esteem as a factor in specific food choices, especially among subpopulations.
