The use of mortality data in setting priorities for disease prevention

The examination of specific disease mortality by five-year age groups helps identify health problems as problems of people and how they live. Traditional methods of examining data in broad classifications tend to obscure etiological factors and the importance of behaviour. Violence, a major cause of death in young adults, gives way to so-called diseases of indulgence in middle age, especially among men who have a much higher death rate than women. Male life expectancy at age 40 has increased only marginally in the past 40 years. Health-related human behaviour must be considered within an ecological framework since social, cultural and physical environmental differences as well as personal factors influence life-style. The responsibility for prevention rests more with the individual and society at large than with health workers. Probability tables, Health Hazard Appraisal (a system of personal risk assessment) and personal counselling can reinforce healthful life-styles and help correct hazardous ones.
