A contraceptive study of rural Bangladeshi women indicated that the previous death of children, number of living children, desire for additional children and son preference were important determinants of contraceptive continuation. The importance of these factors varies to some extent with use of different contraceptive methods.
A two-year controlled clinical study of the effectiveness of postcoital IUD as a continuing contraceptive method in 98 women requesting a postcoital contraception is presented. The control group was selected from women requesting an IUD as contraceptive choice. The rates of accidental pregnancy, expulsion and removal for medical reasons did not differ between the two groups. Removal for personal reasons was the only termination event that showed a significant difference at one year. Moreover, the removal for personal reasons of interceptive IUD users mainly occurred in the early months after insertion. Postcoital IUD has proved to be an effective continuing contraceptive method. Special attention and sympathetic counseling should be given to postcoital IUD users before insertion and during the three months following insertion.

A study of a random sample of 3,564 oral contraceptive acceptors in the Singapore national program clinics with a maximum of 60 months of experience produced findings as follows: The typical pill acceptor was aged 26.9 years with 2.5 children, married for 4.2 years, had at least primary education, was not working, and started on the pill 2.3 months after her last pregnancy. Thirty-three percent of the oral contraceptive acceptors were still continuing with the pill by the cutoff date for the study, 30 June 1972, and the median period of pill use among those still using was 33.6 cycles. The median number of cycles of pill use among discontinued users was only 5.2. The main reasons for discontinuation were side effects of the pill and planned pregnancy. For the discontinued users, 43 percent had used alternative methods of protection, mainly condoms. Cumulative continuation rates per thousand women were 792 after the first cycle, 680 after the third, and 475, 346, 247, and 225 after cycles 12, 24, 48, and 59, respectively.

The continuation contraceptive practise of 3,293 I.U.D., 1985 pill and 749 depo-provera acceptors was analysed by a survey of family planning records. The proportions of grand multiporae were 40.3%, 24.2% and 40.4% in the three groups. Pap smears were taken in from 12 to 38.5% of acceptors and the proportions of pathological smears varied from 8.9 to 13.3%. The percentages of acceptors who attended only once more were 11% (I.U.D.), 18.1% (pill) and 25.1% (d-p.), Pregnancy rates were for the I.U.D., 1.7 per Hundred Woman Years, for the 2.1 per H.W.Y. and for d-p, 0.4, per H.W.Y. Temporary interruptions of the contraceptive methods were common with the pill and d-p. In the long run the I.U.D. is superior to the other temporary methods of contraceptives. Continuation rates with the I.U.D. were 89.9% after one year and 70.9% after five years (similar rates for the pill were 55% and 16.5% and for d-p 50.5% and 10.3%). The importance of a proper pelvic examination and the need to have all methods available for any individual receiving contraceptives are emphasized in the discussion. Tubal ligations should always be considered as an alternative to the temporary methods of contraceptives in ground multiporae and others at special risk from further pregnancies.
This paper proposes a cross-sectional approach to the study of contraceptive continuation and use-effectiveness, based on data from surveys of married women of reproductive age rather than the more conventional follow-up surveys of family planning acceptors. Such an approach has the advantages of indicating the fertility effects of contraceptive practice during a particular period of time and providing information on the experience of users who obtain contraceptive information or supplies from nonprogram sources. An application of the approach in the context of a nationwide survey of wives living in areas covered by the Outreach Project of the Philippine Commission on Population is presented and the findings are discussed in relation both to program management and to the validity of the methodology.
Programs and contraceptive use continuation rates were obtained for a rural Georgia family planning clinic. Program continuation is a measurement of maintenance of clinic attendance, while use continuation is related to actual use of effective contraceptives regardless of clinic activity status. Program continuation rates ranged from 0.77 at 12 months to 0.48 at 36 months. Contraceptive use continuation rates were 0.78 at 12 months and 0.58 at 36 months. Women who moved or were otherwise lost to follow-up formed the largest category of discontinuation. The highest rate of discontinuation from clinic attendance occurred after the first visit with secondary peaks around the time of scheduled annual checkups. Women who were younger and had fewer living children had a greater likelihood of discontinuing clinic attendance and contraceptive use. The reasons for and timing of discontinuation from clinic attendance suggest that clinic personnel should place special emphasis on the first visits, arrange referral for women who might have plans to leave the service area before the scheduled return visit, send reminders before first revisits, and follow up patients soon after missed visits. Priority might be assigned to the younger women of low parity who have been shown to be at higher risk of discontinuation. Other factors which might influence continuation include method of contraception, marital status, and race. Program continuation can be determined by analysis of clinic records alone while contraceptive use continuation often requires follow-up of patients. Although the two continuation rates were not equivalent, program and use continuation were roughly parallel through much of the study period. This suggests that a simple review of records in the clinic or on computer tape, when available, to determine program continuation may give an estimate of actual contraceptive use in the population.
Contraceptive continuation rates-the rates at which people continue to use a particular contraceptive method-can be a great help in determining whether a family planning program is effective or whether new contraceptive methods should be introduced. Until now, very little systematic work has been done to study contraceptive continuation rates in Latin America. The present article reports the results of one of the few existing studies on this subject, which examined the IUD experiences of women admitted to a large family planning clinic in Guatemala City. The study showed that these experiences compared favorably with the IUD experience of groups previously studied in Costa Rica, Taiwan, and the United States.
A study was undertaken at the main PROFAMILIA clinic in Bogota, Colombia to compare the effectiveness of nurses and physicians in the delivery of family planning services. Contraceptive method continuation was the major outcome variable in this analysis. Clients were randomly assigned to physicians or nurses on their first visit and for the duration of care. On all revisits, data were collected pertaining to method prescribed, side effects, pregnancy, and method changes. There was a field survey at eight months to locate clinic drop-outs and determine their contraceptive use status. There were no significant differences in method continuation between clients who received services from physicians and those who received services from nurses. At nine months, the overall continuation of the first method prescribed was 79.1 per cent in the physicians' group and 75.8 per cent in the nurses' group (t = 1.057, p greater than .20). When controlling for first method used, the IUD users in the physicians' group had a continuation rate of 86.1 per cent and in the nurses' group 84.0 per cent (t = 0.556, p greater than .50). Of the pill users who received services from physicians, 78.1 per cent were continuing at nine months and 74.3 per cent of the pill clients in the nurses' group were continuing at nine months (t = 0.573, p greater than .50). There were no differences in pregnancy rates, side effects rates, and method change rates between the two groups. It may be concluded that these nurses were as effective as physicians in the delivery of family planning services.

The renal function of a total of 137 women without renal diseases taking contraceptive steroids continuously but for different periods of time (up to a maximum of 8 years) was investigated by isotope nephrography. Checking is done by using the semiquantitative evaluation prameters according to Zum Winkel. The results show that the application of hormonal contraceptives does not induce significant changes of renal function in the isotope nephrogram.

This paper examines oral contraceptive continuation rates and reported side effects in a large scale clinical research project conducted in Sri Lanka. The project evaluated standard- and low-dose pills used with and without vitamin supplements. Differences in continuation rates and perception of side effects are used to illustrate the impact that family planning field-workers can have on women's use of oral contraceptives.
