6、y，getting the latest possible data from the five countries on areas such as breast cancer and leukemia survival，suicide rates，death rates from asthma,vaccination rates and cancer screening研究表明美国在医疗卫生方面的花销没有使它成为最好的根据星期二发布的研究结果，美国在卫生保健方面的花费是其他富裕国家的两倍，但并设有得到相应的结果。在医疗事件杂志上发表的对五个富有国家的研究中，研究者们发现没有哪个国家有明显的
7、最坏或最好的医疗体系。约翰霍普金斯大学的公共卫生学院的Gerard Arderson及其同事制定出一个21个医疗领域的名单，他们将横向地比较五个国家澳大利亚、加拿大、英国、新西兰和美国。安德森在对记者的电话简报中说：“在这所有的2l项指标里，这五个国家中没有一个始终保持是最好的或最坏的。”“如果你正在寻找一个能够得到最好的医疗的地方，没有这个地方。每个国家至少有一个指标是排在第一位的，也至少有一个指标排在最后。”但是，他说美国的钱花得不值。“鉴于我们比别的国家多花一倍的钱，美国应该尤其关心这些结果。花的钱多并不一定就会有好的结果。”由联邦基金资助的Anderson的国际卫生专家团花了五年的时间

13、measures and public health strategies are needed to shift the overall populati,on risk downward，they add在美国大多数成年人有低风险的心脏疾病根据美国心脏病学杂志上的报告，80%以上的美国成年人在今后十年内患心脏病的风险不到10%。只有3%的人患心脏病的风险超过了20%。来自美国疾病控制中心的第一作者Earl S. Ford博士在一次报告中说：“我希望这些数字能够使外科医生、研究者、卫生政策分析家和其他人更好地了解冠心病在美国人口中的分布状况。”这些研究结果基于对13769个20岁至79岁的实
14、验对象的数据分析得到的，他们参与了1988年到1994年的第三次全国卫生和营养普查。总的来说，82%的成年人患心脏病的风险低于10%，15%的人风险在10%-20%之间，3%的人风险高于20%。实验对象年龄越大，在最高风险组中所占的比例越大;男人进入该组的可能性亦大于女人。对比之下，种族对心脏病风险的分布没有什么作用。来自洛杉矶的西达西奈医学中心的Daniel S. Berman博士和来自加利福尼亚大学的Nathan D. wang博士在一个相关的评论中说道，尽管报告显示大多数成年人十年内患心脏病的风险较低，但是在有风险者中，很大一部分所面临的风险却是很高的或是刻不容缓的。他们补充说，需要积极
15、的治疗措施和公共卫生政策来使整体人口的患病的风险降低。SmokingSince 1939, numerous studies have been conducted to determine whether smoking is a health hazard.The trend of the evidence has been consistent and indicates that there is a serious health risk.Research teams have conducted studies that show beyond all reasonable dou
16、bt that tobacco smoking is associated with a shortened life expectancy.Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and cancer of the throat and is believed to be related to cancer of some other organs of the
17、 body.Male cigarette smokers have a higher death rate from heart disease than non-smoking males.Female smokers are thought to be less affected because they do not breathe in the smoke so deeply.Apart from statistics,it might be helpful to look at what smoking tobacco does to the human body.Smoke is
18、a mixture of gases,vaporized chemicals,minute particles of ash and other solids.There is also nicotine,which is powerful poison,and black tar.As smoke is breathed in，all those components form deposits on the membranes of the lungs.One point of concentration is where the air tube and bronchus divides
19、.Most lung cancer begins at this point.Filters and low tar tobacco are claimed to make smoking to some extent safer, but they can only slightly reduce, not eliminate the hazards.抽烟自 1939年以来，人们进行了无数次研究，以确定抽烟是否危害健康，证据的趋向是一致的，显示出抽烟对健康有严重危害。研究组进行的研究确凿无疑地表明抽烟与人的预期寿命的缩短有关。这个领域的大部分研究人员部认为抽烟是肺癌和喉癌产生的重要原因，并且
20、和人体其他某些器官的癌症有关。抽烟的男性因心脏病而死亡的机率高于不抽烟的男性。女性吸烟者被认为受的影响较小，因为她们不深吸烟。除了统计之外，看一看吸烟对人体的影响也可能会有帮助。烟是各种气体、蒸发的化学物质、微小的灰和其他固体颗粒的混合物。里面还有很强的毒素尼古丁和黑焦油。当烟被吸入时，所有这些成分形成肺膜上的沉淀物，其集中的一点是气管和支气管分叉的地方。大部分肺癌开始于这一点。过滤嘴和焦油含量低的烟草被宣称使抽烟在某种程度上安全一些，但是它们只能稍微降低而不是消除危害。Some Sleep Drugs Do More Than Make You SleepThe United States

28、国国会官员，罗得岛会议员代表Patrick Kennedy说他就有驾车梦游的事，把车撞到类立法人员办公楼附近的安全栅栏上。幸亏事故发生在深夜，所以无人受伤。Kennedy说，那天晚上睡前他服用了安眠药，也服用了使人困倦的胃药。食品及药品管理局并没有说明类似的有记载的驾车梦游的事件有多少。然而，纽约时报去年报道类有关人们承认自己服用Ambien安眠药后有奇怪梦游行为的事件，包括梦游与驾车梦游。也有人在早晨醒来后发现自己梦游时做过饭或吃过东西，但是却不能回忆起睡梦中的行为。食品及药品管理局的一位官员说，治疗睡眠障碍的药物产生类似的严重副作用是比较少见的。不过，他也说道，可能实际病例要比报道的多。他
29、说，食品及药品管理局认为如果人们按照说明谨慎服药，并且服药时不喝酒，这样的危险行为就会减少。食品及药品管理局已经向药品生产厂家提出建议，希望他们能针对这一问题进行研究。Dangers Await Babies with AltitudeWomen who live in the worlds highest communities tend to give birth to underweight babies，a new study suggestsThese babies may grow into adults with a high risk of heart disease and
30、strokesResearch has hinted that newborns in mountain communities are lighter than averageBut it wasnt clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished-many people who live at high altitudes are relatively poor compared with those living
31、 lower downTo find out more，Dino Giussani and his team at Cambridge University studied the records of400 births in Bolivia during 1997 and 1998The babies were born in both rich and poor areas of two cities：La Paz and Santa CruzLa Paz is the highest city in the world，at 3.65 kilometers above sea leve
32、l，while Santa Cruz is much lower，at 0.44 kilometersSure enough，Giussani found that the average birthweight of babies in La Paz was Significantly lower than in Santa CruzThis was true in both high and lowincome familiesEven babies born to poor families in Santa Cruz were heavier on average than babie

34、s team also found that highaltitude babies tended to have relatively larger heads compared with their bodiesThis is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to the rest of t11e body Giussani wants to find out if such babies have a higher risk o
35、f disease in later lifePeople born in La Paz might be prone to heart trouble in adulthoodfor exampleLow birthweight is a risk factor for coronary heart diseaseAnd newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life高海拔地区的婴儿有危险一
36、项新的研究表明，住在世界高海拔地区的女人通常生下体重不足的婴儿。这些婴儿在长大成人后患心脏病和中风的风险很大。研究暗示，在山区出生的新生儿低于平均体重。但是还不清楚这是由于在高海拔地区氧气不足，还是由于他们的母亲没有获得足够的营养许多住在高海拔地区的人相对比住在低海拔地区的人穷。为了了解更多情况，剑桥大学的Dina Giussani 和他的团队研究了1997年至1998年玻利维亚的400个新生儿的记录。这些婴儿出生于两个城市的富有和贫困地区：拉巴斯和圣克鲁斯。拉巴斯是世界上海拔最高的城市，海拔3.65千米，而圣克鲁斯低很多，海拔440米。当然，Giussani发现拉巴斯的新生儿的平均出生体重明
37、显低于圣克鲁斯的新生儿，无论高收入家庭还是低收入家庭都是如此。甚至圣克鲁斯的贫穷家庭的婴儿比拉巴斯的富有家庭的婴儿平均体重还要重。Giussani说：“我们对这个结果感到吃惊。”这个结果表明在高海拔地区出生的婴儿出生前就缺氧。Giussani说：“这可能会触发调节胎儿成长的荷尔蒙的释放或抑制。”他的团队还发现高海拔地区出生的婴儿通常有相对身体来说较大的头部。这可能是因为一个缺氧的胚胎会首先把充氧的血液输送到脑部，然后才送到身体的其他部位。Giussani想要查出这样的婴儿在今后的生活中是不是更容易患病。例如在拉巴斯出生的人在成年之后更可能患心脏病。出生时体重轻是患冠心病的一个危险因素。头部相对
38、身体较大的新生儿在今后的生活中通常更容易患高血压和中风。US Signs Global Tobacco TreatyThe United States has taken the first step toward approving a global tobacco treaty that promises to help control the deadly effects of tobacco use throughout the world. Health and Human Services Secretary Tommy Thompson signed the Framework
39、Convention on Tobacco Control (FCTC) this week at the United Nations. The Senate must still approve the treaty before the US can implement its provisions.The FCTC was developed by the World Health Organization and approved by members of the World Health Assembly，including the United States，last year
40、. Countries that ratify it would be required to enact strict tobacco control policies.For instance, cigarettes sold in those countries would have to have health warnings on at least 30% of the front and back of every pack. The treaty calls for higher tobacco taxes, restrictions on smoking in public
41、places, and more promotion of tobacco prevention and cessation programs. It also requires bans on tobacco advertising, though there are some exceptions for countries like the United States, where the Constitution prohibits such an outright ban.The impact of the treaty could be huge. The World Health
42、 Organization estimates that tobacco use kills nearly 5 million people worldwide every year. In the US alone, about 440,000 people die each year from tobacco-related illnesses; about one-third of all cancers in the US are caused by tobacco use. If current trends continue, WHO estimates, by 2025 toba
43、cco will kill 10 million people each year.The treaty must be ratified by at least 40 countries before it can take effect. So far，109 countries have signed it, and 12 have ratified it.美国签订了全球烟草协议美国朝着批准一项全球性烟草协议迈出了第一步。该协议有望在世界范围内控制使用烟草所产生的致命性影响。卫生和人类服务大臣托米汤普森本周在联合国签署了烟草控制框架性协议(FCTC)。在美国能够实施其条款之前参议院还必须
44、要批准这个协议。FCTC是由世界卫生组织制定的，并且是由世界卫生大会的成员们去年批准的，其中包括美国。批准该协议的国家将被要求制定严格的烟草控制政策。例如，在那些国家出售的香烟将必须在每包烟的正反面至少30%的地方注明吸烟有害健康的警告。这个协议呼吁对烟草收取更多的税，限制在公共场所吸烟和进一步推动禁止烟草的计划。它还要求禁止烟草广告，但是对像美国这样的国家有例外，这些国家的宪法禁止这么直率的禁令。这个协议的影响可能是巨大的。世界卫生组织估计世界上每年有500万人因为吸烟而死亡。仅在美国，每年大约有44万人死于与烟草相关的疾病;美国所有的癌症中约有1/3是因为吸烟导致的。如果目前的趋势持续的话
45、，世界卫生组织估计，到2025年烟草将每年夺取一千万人的生命。这个协议至少被40个国家批准才能生效。到目前为止，109个国家已经签订了这个协议，12个国家已经批准了它。Napping to a Healthier Heart?Researchers say they have developed a simple test that can tell if at person with heart disease is likely to stiffer a heart attack2 The test measures levels of a protein in the blood.
