A/RES/48/96 Page 7 18. The term "handicap" means the loss or limitation of opportunities to take part in the life of the community on an equal level with others. It describes the encounter between the person with a disability and the environment. The purpose of this term is to emphasize the focus on the shortcomings in the environment and in many organized activities in society, for example, information, communication and education, which prevent persons with disabilities from participating on equal terms. 19. The use of the two terms "disability" and "handicap", as defined in paragraphs 17 and 18 above, should be seen in the light of modern disability history. During the 1970s there was a strong reaction among representatives of organizations of persons with disabilities and professionals in the field of disability against the terminology of the time. The terms "disability" and "handicap" were often used in an unclear and confusing way, which gave poor guidance for policy-making and for political action. The terminology reflected a medical and diagnostic approach, which ignored the imperfections and deficiencies of the surrounding society. 20. In 1980, the World Health Organization adopted an international classification of impairments, disabilities and handicaps, which suggested a more precise and at the same time relativistic approach. The International Classification of Impairments, Disabilities, and Handicaps 11/ makes a clear distinction between "impairment", "disability" and "handicap". It has been extensively used in areas such as rehabilitation, education, statistics, policy, legislation, demography, sociology, economics and anthropology. Some users have expressed concern that the Classification, in its definition of the term "handicap", may still be considered too medical and too centred on the individual, and may not adequately clarify the interaction between societal conditions or expectations and the abilities of the individual. Those concerns, and others expressed by users during the 12 years since its publication, will be addressed in forthcoming revisions of the Classification. 21. As a result of experience gained in the implementation of the World Programme of Action and of the general discussion that took place during the United Nations Decade of Disabled Persons, there was a deepening of knowledge and extension of understanding concerning disability issues and the terminology used. Current terminology recognizes the necessity of addressing both the individual needs (such as rehabilitation and technical aids) and the shortcomings of the society (various obstacles for participation). Prevention 22. The term "prevention" means action aimed at preventing the occurrence of physical, intellectual, psychiatric or sensory impairments (primary prevention) or at preventing impairments from causing a permanent functional limitation or disability (secondary prevention). Prevention may include many different types of action, such as primary health care, prenatal __________ 11/ World Health Organization, International Classification of Impairments, Disabilities, and Handicaps: A manual of classification relating to the consequences of disease (Geneva, 1980). /...
