Continuation rate of contraceptive methods and causes of their discontinuation in Zahedan

Although significant success is obtained on birth control in recent decades, but considering limitation of financial sources to control population growth, it seems necessary to conduct more studies on quality usage of contraceptives. Aim of this study to evaluate contraceptive continuation rate and main factors for their discontinuation in Zahedan in year of 2000. 1743 women were chosen who were using one of birth control methods: OCP, IUD, injections and Norplant f r o m beginning of 1998. The mean a of the omen was 27±6 years and mean age of their husband was 33±8 years. Average number of their children were 2.8±2, 89.6% of them were housewife and 28.7% were a. Oral contraceptive was the most popular method of contraception with frequency of 71.2%, and other methods included injection 12.9% , IUD 12.7% and Norplant 3.1% respectively. Kaplan Mayer technique showed that the highest continuation rates for LD 92%), Norplant (86%), IUD (82%), injection (53%) respectively at first year. At the end of three years continuation rate was Norplant users (78%), LD users (70%), 1 1 .Iʹ) and injection (44%) respectively. Common reason for discontinuation of O and injection was change of method and common cause of discontinuation for IUD and Norplant was side effects. Contraceptive continuation was not significantly the level . menʹs education and their husbandʹs, womenʹs job and their husbandʹs, number children and age of last child. Contraceptive continuation in Cox model showed a significant relation with type of contraceptives and health centers. Therefore more studies are proposed for the reasons and proper consultation with women on time of contraceptive methods and up to first six months.
