Summary

The Second Taiwan IUD Follow-up Survey, reported on here, is a representative sample of all IUD acceptors in Taiwan up to the middle of 1966. The data show that 30 months after insertion, 36% of acceptors are continuing users, on a first segment basis, and that if reinsertions are taken into account, the proportion increases to 45%. Compared with extensive clinic data from the city of Taichung, the island-wide termination rates are about 5% higher at 30 months, for first segments, but the all segment rates show little difference at this duration.

Termination rates by social and demographic characteristics show that these rates decline with increasing age and parity, as expected. Sizable differentials in these rates were also found when acceptors were classified as to their purpose in using an IUD—for limiting or spacing—and as to their desire for more children. These effects were partially independent of age and parity. These ‘motivational’ variables were used in cross-tabulations to show how they might clarify the effect of age and parity, as well as to derive a number of other implications for the evaluation and operation of a family planning programme. The effects of education, urban-rural residence, and prior use of contraception, on IUD termination are studied in some detail by cross-classifying these characteristics with age and with one another.

Lastly, this study presents reinsertion rates in relation to a number of social and demographic factors. The rate of reinsertion is seen to depend on the type of termination and, taking this into account, to be generally inverse to the patterns of termination by social and demographic characteristics.
