Fact Sheet N°84
Ethically Correct, Economically Sound
Hundreds of millions of people throughout the world are employed today in conditions that breed ill health and/or are unsafe.
Making working conditions safe and healthy the raison d' être of occupational health is in the interests of workers, employers and governments, as well as the public at large. Seemingly obvious and simple, this idea has not yet gained meaningful universal recognition.
The reasons for that are numerous and complex and include perceptions that there will always be plenty of young and strong workers to replace the old ones, both on production lines and in pension funds. Within the next 30-40 years, this will probably no longer be the case everywhere.
The burden of occupational diseases and injuries and world trends in this area should be a matter of special concern. Particularly, because today's picture is almost certainly based on underestimates.
Underestimated: The evaluation of the global burden of occupational diseases and injuries is difficult. Reliable information for most developing countries is scarce, mainly due to serious limitations in the diagnosis of occupational illnesses and in the reporting systems. WHO estimates that in Latin America, for example, only between 1 and 4 % of all occupational diseases are reported. Even in industrialized countries, the reporting systems are sometimes fragmented. For example, a 1993 economic impact analysis of hazardous substances regulations in Australia found data lacking in many areas and had to rely on extrapolations from Scandinavian and USA data.
There are two main problems common in developed as well as developing countries: unwillingness to recognize occupational causes of injuries or health problems, and failure to report them even when recognized. The history of occupational health is that of a struggle between workers fighting for protection and preventative measures or compensation, and their employers seeking to deny or reduce their liability for work-related diseases and injuries. This conflict has greatly influenced statistical reporting. As a result, the burden of disease due to occupational exposures is normally underestimated.
Economic Impact: The health status of the
workforce in every country has an immediate and direct impact on national and world
economies. Total economic losses due to occupational illnesses and injuries are enormous.
Such losses are a serious burden on
economic development. Thus, apart from health
considerations, the improvement of working conditions is a sound economic investment:
Population Ageing: In certain industrialized countries, within the next quarter-century, population ageing (with fewer children born and more people living longer) will change considerably the proportions between working and retired populations. This will undoubtedly increase pressure on the workforce for higher productivity and greater contributions to pension funds. Only a healthy workforce will be able to bear this pressure.
Occupational Hazards and Exposures: Hundreds of millions of workers in both developed and developing countries are at risk from exposure to physical, chemical, biological, psychosocial or ergonomic hazards in the workplace. For many of these people there is often the risk of combined exposures to different occupational hazards.
Occupational Health and Women:Women have been joining the workforce in increasing numbers, in sectors that include agriculture, industry and services, making up about 42% of the estimated global working population. Although they contribute appreciably to national economies, their special needs are seldom adequately met, even when they have access to some occupational health service.
Child Labour: According to the ILO, of the 250 million children between the ages of 5 and 14 working in developing countries today, nearly 70% work under hazardous conditions. Asia has the most child workers with 61% of the global total, Africa has 32%, and Latin America 7%. Africa, however, leads in the proportion of working children, with around 41% of all children aged between 5 and 14; the proportion in Asia is 22%, and in Latin America 17%.
Vulnerable Populations: Women, migrants, minorities and children are particularly vulnerable to occupational hazards. This is especially true in the informal sector, where workers are not necessarily protected and are often subjected to highly unsafe conditions in makeshift factories. Entire families may be exposed to hazards associated with industrial processes in the home, or entire communities may be affected by uncontrolled hazardous emissions from factories located adjacent to their homes.
WHO's Response: Since its inception in 1948, WHO has recognized the utmost importance of improving the health status of working populations and has been developing international collaboration in this area. Today, WHO Collaborating Centres carry out research, analyse data, identify trends, prepare and disseminate reports and make recommendations for national public health services and decision-makers. However, developing countries are yet to be fully involved in this work.
In order to arrive at more accurate estimates of the global burden of occupational disease and injuries, there is a need for further improvements and standartization of occupational health reporting in all countries, most particularly in developing countries. Another area, which needs particular attention, is the development of methods to estimate the economic impact of occupational injuries and diseases, as well as the cost-effectiveness of early occupational health interventions.
At present, the emphasis of WHO's Occupational Health Programme is on data collection and analysis, research, formulation of strategies and recommendations for hazard prevention and control, human resource development with special emphasis on developing countries, as well as rational development of the international network of collaborating centres.
WHO's Occupational Health Programme also addresses groups of workers with special needs. These include women and workers in small enterprises or in the informal sector, who are usually not covered by legislation and do not have access to occupational health services.
Strengthening international partnerships in the field of occupational health is yet another area of importance. WHO has paid special attention to cooperation and coordination of its work with the ILO, which works hand in hand with WHO to protect the workforce and to ensure safety and health at work. The Joint ILO/WHO Committee on Occupational Health meets periodically to review occupational health priorities and to make appropriate recommendations for international action.
WHO collaborates actively with the International Commission of Occupational Health (ICOH), the International Occupational Hygiene Association (IOHA), the International Ergonomic Association (IEA), the European Commission (EC) and other nongovernmental and inter-governmental organizations striving to protect the health of workers.
WHO has also launched the Prevention And Control Exchange (PACE) initiative, which aims at the development of national capabilities in the field of primary prevention of occupational hazards. This is achieved through the promotion of awareness and political will, transfer of appropriate technologies, development of human resources, promotion of applied research and information dissemination. On-going activities include the preparation of documents on the prevention and control of specific hazards, such as noise and dust. The publication on dust is also relevant to the Joint ILO/WHO International Programme on the Global Elimination of Silicosis.
Each year, WHO and its Collaborating Centres and NGOs plan joint activities to implement the Global Strategy on Occupational Health for All.
