[Interruption of pregnancy in Switzerland 1982-1986].

Official statistics available for the 5-year period considered in this paper reveal a general trend: decrease in the number of terminations, in absolute terms, both in women non-resident and in women resident in Switzerland. Amongst the latter, figures show a relative decrease in the 15 to 44-year age group and in relation to birth rate. Attitudes in 'liberal cantons' concerning termination of pregnancy are clearly justified. Efforts to ensure more widespread use of modern contraceptive methods must be continued (in conjunction with AIDS prevention).
