Continuation of Contraception on Java-Bali: Preliminary Results from the Quarterly Acceptor Survey

Abstract

Review of recently tabulated contraceptive continuation and pregnancy rates for Java-Bali and the constituent provinces. It was found that IUD continuation rates are higher than those for pill or condom, although considerable variation between provinces occurs. East Java and Bali seem to be recording the most and Jakarta and Yogyakarta least success in use continuation. Older, higher parity acceptors tend to use for longer periods, irrespective of method. Similarly, age and parity do not seem to affect the relationship between pill, IUD and condom continuation rates. Pill acceptors are more likely to terminate for physical, emotional, or health reasons than condom or IUD acceptors. Younger and lower parity groups show a greater likelihood of termination in order to have another child. Sources of bias in the rates were also examined. Using a rough adjustment procedure it was found that women lost to follow-up are not a serious bias in the 1st round results, with the exception of differential response by province. As subsequent rounds of the survey are completed, however, the lost-to-follow-up bias is likely to be a more important source of error in reported continuation rates. Factors to adjust acceptor statistics for women who denied ever using family planning were also presented.
