USE EFFECTIVENESS OF IUD A CLINICE IN ISPHAHAN

Abstract

Previous studies have revealed that the results of most conteroceptive devices, especially IUD, show similar patterns at various localities. However, certain differences have also been observed. The present study describes the pattern of IUD use effectiveness at Aalami-Harandi clinic in Isphahan over a four year period (March 1976 up to May 1980). When compard with previous study carried out at Farman –Farmaian Health Center Tehran in 1975, certain differences were obvious. The probability of pregnancy after 6 months and 1 year in present study has been 1.26% and 2.72% respectively whereas similar data for the previous study was 0.28% and 0.76%. The expulsion rate for the present study was twice as high as in the previous study and the probability of retention after one year was 70.15% which is about 8% less than the study done at Farman Farmaian Health center. The differences between two studies are ascribed to the characteristics of the population attending these clinics, which were mainly manual laborers in present study.
