Autonomy and coercion in disease prevention and health promotion

Most of the attention regarding the balance between autonomy and paternalism has been focused on the therapeutic relation. Much less attention has been devoted to the problem of autonomy in the application of medical knowledge for preventive purposes. Here, because the good to be achieved is social as well as individual, an unavoidable dilemma ensues. Effective preventive measures of benefit to all must necessarily limit autonomy and involve some coercion. I argue that there are principles which can be established to guide society in a moral use of coercion. The question of employing medical knowledge is not, as it is in therapeutic medicine, to preserve or enhance autonomy. Rather its aim is to enhance voluntary co-operation. Principles for moral use of coercion must thereby be derived from health as a moral value.
