The measurement of physical activity is an important issue in health promotion and Public Health campaigns in Australia. This paper examines six community-based national surveys since 1980, each estimating the prevalence of physical activity. These surveys show an apparent increase in the number of highly active Australians. However, the issue of reliable and valid physical activity measures has not been adequately addressed. The different measures used generated different estimates of activity prevalence. Serial surveys in 1985 and 1986, when adjusted for differential measurement error, failed to demonstrate an increase in the number of active Australians. Consistent and validated measurement of physical activity patterns is necessary before public health and preventive programs are developed in this area. 相似文献

The prevalence of byssinosis in a sample of cotton ginnery workers in Greece was investigated. The respiratory symptoms, F.E.V. 1·0, and V.C. of 70 male ginnery workers were recorded. No case of clinical byssinosis was found, but a statistically significant relationship exists between years of exposure to cotton dust and impairment of lung function. On the contrary no significant relationship exists between smoking and lung function, or between sputum production and lung function. The findings suggest the hypothesis that the cotton dust may exert, in the case of a prolonged exposure, a chronic deleterious action without producing the typical symptoms of clinical byssinosis. 相似文献

当年幼的孩子步入青春期,就意味着打开了人生的另一扇大门,虽然眼中的世界依旧精彩.但是他们已经学会思考。伊甸园里那个能辨识善恶的苹果,想是这个时候被偷食的.不然亚当、夏娃吃后怎么会因彼此衣不遮体而顿感羞涩。同懵懂的孩童相比他们显然有了较强的性别意识.然而正是这种性别意识让处在青春期的青少年被置于一个尴尬的境地。事实上尽管他们兼具儿童和成年人的某些特点,但他们既不是儿童.也不是成年人,而是经历着人生从生理、心理和社会性全面走向成熟的重要阶段。[编按] 相似文献

随着生活水平和社会开放程度的不断提高,现在的青少年"成熟"得越来越早.相比父辈所受到的传统观念的影响,他们更多接触到的是新事物、新文化的冲击.在校园里,异性的交往和接触日显活跃.与此同时,一些书报、网络和影视中司空见惯的亲吻、搂抱的刺激镜头,无形中助长了青少年对性这个"神秘世界"的好奇心和"探索"欲. 相似文献

随着医院市场化步阀的加快,人民群众维权意识的加强,医患关系日趋紧张,"看病难、看病贵"的呼声一时鹊起。为了缓和医患矛盾、促进医患和谐,如何加强医院物价管理不单是患者与主管部门的要求,也是医院加强自身管理与制度建设的重点工作之一。 相似文献

自1991年4月以来,通过对报告的急性弛缓性麻痹(AFP)病例和病人接触者的粪便标本检测,山东省未发现脊髓灰质炎(脊灰)野病毒。自1992年开始引用世界卫生组织(WHO)的诊断标准,每年均有一定数量的临床确诊脊灰病例。WHO提出,分离到野病毒作为唯一的确诊依据,在消灭脊灰后期很有必要。卫生部提出,在WHO推荐标准基础上结合专家组诊断意见,能保证临床符合病例具有较高特异性。山东省所有确诊脊灰病例均由专家组诊断,对专家组诊断的临床脊灰病例仍应引起高度重视,以便综合分析是否有野病毒引起的可能。15岁以下儿童非脊灰AFP病例报告发病率已连续3年达到1/10万的指标,AFP病例的粪便标本采集率达到80.2%,与医院的及时报告率提高有密切关系。受病例麻痹到就诊的时间间隔和其它客观因素的影响,麻痹两周内采集到合格粪便标本的期望比例为93.5%,市、县两级医院能否及时报告和采便是提高监测系统敏感性和质量的关键。报告AFP病例中经省专家组诊查剔除非AFP病例191例,占报告病例的31.2%。在强调监测敏感性的同时,也应注意提高监测工作的特异性,以全面提高监测工作的质量。 相似文献

江苏省1991年建立起急性弛缓性麻痹(AFP)病例监测系统,1996年各项监测指标达到或基本达到消灭脊髓灰质炎(脊灰)工作的要求。1996年共报告AFP病例191例,其中临床诊断脊灰3例,15岁以下儿童非脊灰AFP病例报告发病率以市为单位均已达到1/10万。我省已连续4年未发现由脊灰野病毒引起的麻痹病例,标志着我省已进入消灭脊灰后期关键阶段 相似文献

面对当前医院发展的新形势和新特点,每年都会有大批医学院校毕业生进入医院,为使每一个入院的新职工顺利完成从单纯的校园生活到社会生活的转变,完成从单纯的学生到合格医务工作者的转变,完成从拥有文凭到拥有能力的转变,树立职业理想,尽快进入角色,对新职工进行岗前教育培训,已成为医院人力资源管理的一项常规工作。它是医院人才培养的第一步,也是作为加强医院人才队伍 相似文献

Following a summary background to the research, development and diffusion of in vitro fertilization (IVF) and related technologies in Australia from 1971 to 1989, two arguments are developed. The first is that what evaluations have so far been done of the safety, efficacy and effectiveness of the techniques used in this country have revealed worrying results. The second suggests that the existing methodologies of technology assessment and ethical control of human experimentation are themselves too limited to meet the recent goal, adopted by the 1988 Australian Health Ministers' Conference, of reducing inequities in health. The discussion offers suggestions for a more comprehensive methodology for the technical, ethical and social evaluation of these (and other) medical and health technologies, derived from recent social science research. 相似文献

One-second forced expiratory volume (F.E.V. 1·0) and forced vital capacity (F.V.C.) were measured before starting work in five flax hacklers with symptoms of grade II byssinosis and in five matched controls. Similar measurements were taken in each group at the end of the day shift. A significant (P < 0·05) decline in F.E.V.1·0 was observed in the hacklers during the day on Monday, Tuesday, Wednesday, and Friday. The F.V.C. also declined significantly in the hacklers on Monday, Tuesday, and Wednesday. In the control group, ventilatory function tended to decline during the day, but this was significant only for F.E.V.1·0 on Monday. The reason for this is discussed. Variations in the dust concentrations in the mill and in outdoor air pollution are shown to be unlikely to have affected the findings. Morning values of F.E.V.1·0 and of F.V.C. were consistently lower in the byssinotic group than in the matched controls, suggesting that the inhalation of flax dust causes not only daily variations in lung function but longer-term impairment of ventilatory capacity as well. Additional evidence is given for this conclusion from two other studies. 相似文献

1992年夏,在呼和浩特市所辖6个旗(县、区)随机采集384名2~39岁正常人的血标本,检测麻疹血凝抑制(HI)抗体。结果阳性 376人,阳性率为 97.92%。几何平均滴度(GMT)为 1:18.45。经统计学处理,各年龄组之间、男女之间、城乡之间的抗体阳性率和GMT均无显著性差异;不同地区之间在抗体阳性率上无显著性差异,但GMT却有显著性差异.从本次结果看,本市近期内不会有麻疹流行。 相似文献
