RESUMO
PIP: In an attempt to investigate in detail clients' reasons for discontinuing use of a particular contraceptive, a study was undertaken to develop and test a system of classification that would allow precise categorization of individuals in the study and to ascertain detailed medical and social reasons for discontinuing contraception. A total of 666 women, who had accepted a family planning method from 1 of 14 health clinics administered by the Bangkok Metropolitan Health Authority over a 6-month period in 1977, were traced and interviewed 1 year later. Of these, 46% were still using their initial method of contraception and their original supply source. A further 29% had changed either their method or their source of supply or both, and 26% were not using any contraception. The most frequent reason given for discontinuation referred to medical side effects; the 2nd most frequent reason was the woman's feeling that she had no need for contraception. However, the study indicated that preconceived ideas of a contraceptive method, rather than the side effects experienced, may play a leading role in determining whether the method will continue to be used.
