health of the elderly

the increase in the number of old people in the world will be one of the most profound forces affecting health and social services in the next century. overall， the world s population has been growing at an annual rate of 1.7% during the period 1990-1995 - but the population aged over 65 is increasing by some 2.7% annually. of a world total of 355 million people over 65 in 1993， more than 200 million are in the developing world， where they make up 4.6% of the population， with more than 150 million in developed countries， where the proportion is 12.6%. although europe， japan and the usa currently have the "oldest" populations， the most rapid changes are being seen in the developing world， with predicted increases in some countries of up to 400% in people aged over 65 during the next 30 years.

alongside the increase in the number of people over age 65， there will also be a dramatic rise in the numbers of "old old" - people over 80. in 1993 they constituted 22% of those over 65 in developed countries and 12% in the developing world. the world elderly support ratio (the number of people over 65 years compared to those aged 20-64) in 1990 was 12 elderly to every 100 people of working age. it is estimated that the figure will be 12.8 in the year 2000 and 13.2 in . in other words， while population increase during1990-2000 is estimated to be 17%， the increase in the number of elderly is likely to be 30%.

one of the most difficult questions for health planners and politicians trying to allocate funds， as well as for the community and individuals themselves， is whether increased life expectancy means more health or simply more years of sickness. this is an area that is greatly underresearched， yet the question is assuming ever greater importance.

two of the most pressing problems in the future will be the provision of care for people with dementia and those needing joint replacements for arthritic diseases. who estimates that there are 165 million people in the world with rheumatoid arthritis. the long-term care of the frail elderly is becoming one of the most debated medical and political issues in many developed countries， and the developing world too will soon have to wrestlewith it. if people are not to be left destitute and uncared for at the end of their lives， more attention must be given to social mechanisms for the support of the elderly and the means to fund them.

general health issues

although in the past 10 years there has been a global trend towards the democratization of political systems， the much anticipated "peace dividend" has failed to materialize. poverty has continued， and will continue， to be a major obstacle to health development. the number of poor people has increased substantially， both in the developing world and among underprivileged groups and communities within developed as well as developing countries. during the second half of the 1980s， the number of people in the world living in extreme poverty increased， and was estimated at over 1.1 billion in 1990 - more than one-fifth of humanity.

the changing demographic picture across the world， together with the rapid shift towards urbanization， will have profound implications for the delivery of health services. the unplanned and often chaotic growth of megacities in the developing world will pose particular challenges， as poor sanitation and housing encourage the spread of infectious diseases.

against any optimism about the global economy throughout the remainder of this century and beyond should be set a number of major uncertainties. there has been a disproportionate flow of resources from the developing to the developed world - poor countries paying money to rich ones - because of debt servicing and repayment and as a consequence of prices for raw materials that favour the latter at the expense of the former. structural adjustment policies aimed at improving the economic performance of poor countries have in many cases made the situation worse. the words of robert mcnamara， spoken in 1980 when he was president of the world bank， still hold true: "the pursuit of growth and financial adjustment without a reasonable concern for equity is ultimately socially destabilizing".

a further worrying global trend is growing unemployment， especially in developing countries without social security arrangements to cushion those out of work. long-term unemployment is creating a new class of "untouchables" - by excluding a large group of people from the mainstream of development and society. the unemployed are a potent reminder of the dangers of assuming that the general prosperity of a country will trickle down to all its members.

there is also considerable concern about the adverse health effects of continuing environmental degradation， pollution and the uncontrolled dumping of chemical wastes， diminishing natural resources， depletion of the ozone layer and predicted global climate changes.

social mores are also undergoing profound changes， with a move towards shorter marriages and more divorces in many countries， leading to family breakdowns which have repercussions for individuals and for social services that may be called on to provide help for children and single parents.

beyond any considerations for improving the health of the world must be the recognition that the growing world population will strain to the limit the ability of social， political， environmental and health infrastructures to cope. health infrastructure - buildings and equipment， the staff， the drugs， the vehicles - is central to good health care. services must be integrated， cost-effective and provided as close as possible to the people who need them.

with health resources unlikely to be greatly increased but with ever growing demands for services， because of expanding populations and the advances of science which make more conditions treatable， the debate about the rationing of health care， with the attendant ethical problems， is likely to become intense. hard choices will have to be made - and greatly enhanced mechanisms found for listening to the voice of the health consume

who"s contributions to world health

within the framework of the organization s constitution and the guidance given in the periodic general programmes of work， all who activities are geared to respond to the priority problems of the age groups referred to in this summary. the full extent of who"s work at national， regional and global levels cannot be reflected here， but examples are given of different types of action.

child and adolescent health

who encourages self-reliance of countries in conducting immunization through basic health services. it cooperates with unicef in its initiative of supplying vaccines to over 100 countries. major priorities are to at least sustain the accomplishments of previous years and to continue to strive for achievement of the 1992 world summit for children goal of immunization against the six vaccine-preventable diseases (diphtheria， pertussis， tetanus， measles， poliomyelitis， tuberculosis).

in an effort to make the best use of limited resources to eliminate neonatal tetanus， who has given priority to countries that account for 80% of total cases and have an estimated mortality of 5 or more per 1 000 live births. who initiated a series of measures to arrest the spread of diphtheria in eastern europe， including the formulation of a plan of action and the establishment of a european task force. in 1993 progress towards the poliomyelitis eradication goal was heartening. efforts are being made to develop a more heat-stable poliovirus vaccine that can be delivered with a less rigorously maintained cold chain. large donations for poliomyelitis eradication were coordinated with different organizations. in 1994 the region of the americas committed itself to eliminating measles by the year 2000， and incidence is now at the lowest level ever. if the momentum is sustained the americas may well lead the way towards global elimination of this major killer of children.

by the end of 1994 virtually all developing countries had implemented plans of action against diarrhoeal diseases in children. nearly 42% of health staff in the countries had been trained in supervisory skills using materials developed by who， and almost 30% of doctors and other health workers had been trained in diarrhoea case management， many of them in the more than 420 diarrhoea training units established in over 90 countries. it is estimated that nearly 85% of the population of the countries had access to oral rehydration salts at the end of 1994.

particular emphasis is given to training in the management of acute respiratory infections who supports courses for workers in first-level health facilities and referral hospitals on standard case management， and distributes training and technical materials. more than 190 000 health managers， doctors， nurses and community health workers in over 60 countries have been trained so far. who is involved in numerous studies on acute respiratory infections in africa， asia and latin america.

activities for better nutrition are promoted in 62 countries， mostly in collaboration with fao and unicef. a global database on child growth was established and more than 90 countries are receiving technical and financial support to give effect to the international code of marketing of breast milk substitutes. the new who/unicef "baby-friendly hospital initiative" has proved hugely successful in encouraging proper infant feeding practices， starting at birth. it has already been implemented in two-thirds of african countries. a number of countries have introduced national nutrition policies with who support.

a wide range of who programmes focus on the needs of adolescents in such fields as nutrition， mental health， sexuality， disease and injury prevention， and substance abuse. a joint unicef/who/unfpa policy statement on the reproductive health of adolescents was disseminated. who supported the formulation of policies on adolescent health in 20 countries.

who activities broadly seek to improve and maintain the economic and social productivity of adults by promoting health and reducing premature morbidity and mortality.

as far as the major communicable diseases are concerned， efforts are being made to mobilize financial support to combat tuberculosis， which recently has shown a worrying resurgence. control programmes were reorganized in several countries， and operational and other studies were supported. the research has produced some important results which may have major implications for policy. a study of rifapentine suggests that it is a promising new drug. a large trial is being organized on the efficacy of sparfloxacin， another new drug， against multidrug-resistant tuberculosis. a study in uganda on the feasibility of tuberculosis chemoprophylaxis for hiv-infected persons suggests that this intervention is not easily applicable on a large scale in a developing country setting. who"s global task force on cholera control continues to support activities to strengthen national capacity to prepare for and respond to epidemics. several cholera vaccines are at different stages of development. all 45 countries where malaria is endemic received who financial support for control activities. national plans of work， based on a revised regional control strategy， were drawn up in a number of african countries. who， together with other agencies and ngos， responded promptly to requests for assistance in combating malaria epidemics in seven countries， including outbreaks among the 500 000 or so rwandan refugees. in view of the rapid spread of chloroquine-resistant and multidrug-resistant falciparum malaria， a multicentre research programme has been initiated to study ways of retarding development of drug resistance. the synthetic colombian malaria vaccine spf66 has been shown to be safe， to induce antibodies and to reduce the risk of clinical malaria by around 30% among children aged under 5 in the united republic of tanzania.

with regard to the other communicable diseases， all countries where leprosy is endemic have implemented national strategies and plans for elimination of the disease as a public problem by the year 2000. the onchocerciasis control programme in west africa， executed by who with support from undp， fao and the world bank， has succeeded in eliminating the disease as a public health problem in 11 endemic countries. remarkable progress has been made in eradication of dracunculiasis. national eradication programmes are under way in the 18 endemic countries. a reliable village-based surveillance system has also been implemented， with monthly reporting in operation in all countries. who is supporting a campaign to eliminate chagas disease from the southern cone of the americas. activities include the development of slow-release insecticidal paints which have shown to be nearly twice as effective as traditional sprays in controlling the triatomine vectors and about half as expensive. seven-day treatments with eflornithine have been shown to be effective against trypanosomiasis. as the drug is expensive， who has arranged to provide it to four countries on a cost-recovery basis， and is participating in the development of a low-cost synthesis and production method. support is given for research and training in the epidemiology and control of schistosomiasis， and a new candidate vaccine has been identified. emergency supplies for serological diagnosis and drug treatment of visceral leishmaniasis were provided by who and unicef during a recent epidemic in sudan. the outbreak of pneumonic plague in india in 1994 was a stern reminder that the disease often regarded as a scourge of the past still exists. who intervened promptly at the request of the indian authorities. travel advice was issued based on the international health regulations and an international team of experts was set up to conduct a thorough investigation. the results suggested that the outbreak involved far fewer cases than the number reported. no evidence was found of the plague spreading outside the focus; and no imported， confirmed plague was detected in any other country.

programmes against hiv/aids are under way with who support in most member states， including hiv surveillance activities in some 80 developing countries. similarly， staff from 80 countries were trained in hiv/aids programme management. agreements were concluded for bulk purchase of hiv test kits， ensuring quality and the best possible price for developing countries. a safety trial of a candidate vaccine against hiv， endorsed by who， was conducted for the first time in a developing country. policy guidance is given in such fields as blood safety， restrictions on hiv-positive travellers and hiv testing. hundreds of ngos and networks of organizations work with who in the fight against hiv/aids.

who is developing a network of centres and a database in support of a global programme to monitor and prevent cardiovascular diseases， and continues to coordinate the 10-year， 26-country monica project which monitors trends and determinants in cardiovascular diseases and measures the effectiveness of interventions. national programmes for the prevention of coronary heart disease were introduced in 41 countries. sixteen inter-health demonstration projects have been set up worldwide (9 of them in developing countries) to assess the effectiveness of integrated community-based intervention. the related cindi programme now covers 21 countries in europe. who supports the implementation of national cancer pain relief and palliative care policies in 46 countries， and participates in the development of national cancer registers. a model list of 24 essential drugs for cancer chemotherapy was updated. guidelines were produced on ethical issues in human genetics， and on the provision of genetic services for control of hereditary diseases. national programmes for control of diabetes and rheumatic diseases were established in several countries.

guidelines on mental retardation， epilepsy and suicide and other aspects of mental health were issued. studies are promoted on the long-term course and outcome of schizophrenia and obsessive/compulsive disorders. an international review of mental health legislation was undertaken. as part of efforts to prevent substance abuse， recommendations were made on international control of psychoactive substances and support is given to member states in revising policies and legislation on treatment and rehabilitation of drug and alcohol dependence.

"africa 2000"， a new investment initiative aimed at providing universal coverage of water supply and sanitation services， was launched. a broad programme of hygiene education and promotion of low-cost sanitation is being developed in cooperation with unicef and other organizations. training packages and manuals on the proper operation， maintenance and optimization of systems are being prepared， and one on health in water resources development is being tested. the healthy cities initiative now covers over 650 cities worldwide. the global who/unep networks for monitoring air and water quality are operational in more than 60 countries. revised who guidelines on drinking-water quality were issued. who and fao support the codex alimentarius commission in promoting the adoption of scientifically-based national food legislation. together with fao， who has established acceptable daily intakes for well over 700 food additives， contaminants and veterinary drug residues in food.

【医学口语】世界卫生状况英文报告2 篇2

the world"s biggest killer and the greatest cause of ill-health and suffering across the globe is listed almost at the end of the international classification of diseases. it is given the code z59.5 - extreme poverty.

poverty is the main reason why babies are not vaccinated， why clean water and sanitation are not provided， why curative drugs and other treatments are unavailable and why mothers die in childbirth. it is the underlying cause of reduced life expectancy， handicap， disability and starvation. poverty is amajor contributor to mental illness， stress， suicide， family disintegration and substance abuse. every year in the developing world 12.2 million children under 5 years die， most of them from causes which could be prevented for just a few us cents per child. they die largely because of world indifference， but most of all they die because they are poor.

in the time it takes to read this sentence， somewhere in the world a baby has died it its mother s arms. for that mother， the message that her neighbour"s infant will live is no consolation. it does not stem her grief to know that 8 out of 10 children in the world have been vaccinated against the five major killer diseases of childhood， or that globally since 1980 infant mortality has fallen by 25%， while overall life expectancy has increased by more than 4 years， to about 65 years.

beneath the heartening facts about decreased mortality and increasing life expectancy， and many other undoubted health advances， lie unacceptable disparities in health. the gaps between rich and poor， between onepopulation group and another， between ages and between the sexes， are widening. for most people in the world today every step of life， from infancy to old age， is taken under the twin shadows of poverty and inequity， and under the double burden of suffering and disease.

for many， the prospect of longer life may seem more like a punishment than a gift. yet by the end of the century we could be living in a world without poliomyelitis， a world without new cases of leprosy， a world without deaths from neonatal tetanus and measles. but today the money that some developing countries have to spend per person on health care over an entire year is just us $4 - less than the amount of small change carried in the pockets and purses of many people in developed countries.

a person in one of the least developed countries in the world has a life expectancy of 43 years according to 1993 calculations. a person in one of the most developed countries has a life expectancy of 78 - a difference of more than a third of a century. this means a rich， healthy man can live twice as long as a poor， sick man.

that inequity alone should stir the conscience of the world - but in some ofthe poorest countries the life expectancy picture is getting worse. in five countries life expectancy at birth is expected to decrease by the year 2000， whereas everywhere else it is increasing. in the richest countries life expectancy in the year 2000 will reach 79 years. in some of the poorest it will go backwards to 42 years. thus the gap continues to widen between rich and poor， and by the year 2000 at least 45 countries are expected to have alife expectancy at birth of under 60 years.

in the space of a day passengers flying from japan to uganda leave the country with the world s highest life expectancy - almost 79 years - and land in one with the world s lowest - barely 42 years. a day away by plane， but half a lifetime s difference on the ground. a flight between france and c?te d"ivoire takes only a few hours， but it spans almost 26 years of life expectancy. a short air trip between florida in the usa and haiti represents a life expectancy gap of over 19 years.

the purpose of the report is to highlight such inequities and to tackle the wider question: what are the global health priorities? it also tries to answer other crucially important questions. which are the major diseases， the major causes of death， handicap， disability and diminution of the quality of life? which conditions cause most misery， although they may not be fatal? which countries， or communities within countries， have the greatest health needs? where should health resources be targeted?

the report， for the first time， has attempted to examine the burden of ill-health not just by disease， but also by age， as the impact of illness differs across the age spectrum. where possible， the analysis of health status has been carried out for infants and children， adolescents， adults and the elderly. on the basis of the data available and considered to be reasonably reliable， ten leading causes of death， illness and disability have been identified. there is also an explanation of what who is doing to bridge the gaps in health， an attempt to assess health trends in the coming years， and an effort to chart a health future for mankind - a future in which a baby lives， not dies， in its mother"s arms.

child health

the number of children under 5 years who died in 1993 - more than 12.2 million - equals the entire populations of norway and sweden combined. of such deaths in the developing world， the great majority could have been avoided if those countries enjoyed the same health and social conditions as the world s most developed nations. the gap between the developed and the developing world in terms of infant and child survival is one of the starkest examples of health inequity.

the estimated global figure for mortality among children under 5 years in 1993 was 87 per 1 000 live births， an encouraging fall from rates of 215 during the period 1950-1955 and of 115 in 1980. yet in parts of the developed world only 6 out of 1 000 liveborns die before reaching age 5， whereas in 16 of the least developed countries the rate is over 200 per 1 000， and in one country it is 320 per 1 000.

infant mortality - deaths of children under 1 year - varies from 4.8 per 1 000 live births to 161 - a 33-fold difference. the gap in infant mortality between developed and developing world narrowed by 50% during the years 1960-1993， from 113 to 54 per 1 000 live births. but at the same time the gap widened between least developed and developing countries.

malnutrition contributes substantially to childhood disease and death but often goes unrecognized as such. in 1990 more than 30% of the world s children under 5 years were underweight for their age. as many as 43% of children in the developing world - 230 million - have low height for their age. micronutrient malnutrition is estimated to affect at least 2 billion people of all ages， but children are particularly vulnerable. as a result of iodine deficiency - a public health problem in 118 countries - at least 30 000 babies are stillborn each year and over 120 000 are born mentally retarded， physically stunted， deaf-mute or paralysed. a quarter of all children under age 5 in developing countries are at risk of vitamin a deficiency.

there have been improvements in child health， and 1993 saw the number of children dying from vaccine-preventable diseases reduced by 1.3 million compared to 1985 - equal to the population of trinidad and tobago. nevertheless， around 2.4 million children under 5 years are still dying every year from such diseases， particularly measles， neonatal tetanus， tuberculosis， pertussis， poliomyelitis and diphtheria. there are also worrying signs that recent immunization gains are being eroded or even reversed by economic and social conditions.

every year in the developing world acute respiratory infections， particularly pneumonia， kill more than 4 million children under 5 years - one death every 8 seconds - and are a leading cause of disability. they account for 30-50% of visits by children to health facilities everywhere. significant reductions in mortality could be achieved by treating the underlying bacterial infections with low-cost antibiotics for a few days.

diarrhoeal diseases， resulting from unsafe water and poor sanitation coupled with poor food-handling practices， are responsible for a further 3 million deaths a year among children under age 5 in the developing world - one every 10 seconds - and are a graphic example of the deadly synergy of poverty and lack of knowledge. worldwide there are an estimated 1.8 billion episodes of childhood diarrhoea annually. many of the deaths from diarrhoea could be prevented by using oral rehydration salts， which cost just us $0.07 on average.
