A follow-up study of oral-contraceptive and intrauterine-device acceptors in the early years of the Ceylon family planning programme was undertaken to determine the effect of a 1968 policy decision to cut the per cycle price of oral contraceptives by half and to allow nonclinical prescription and distribution of the pills by trained field midwives under medical supervision. While pill acceptance increased, study findings suggest that continuation did not. On balance, the intrauterine device proved much more effective than oral contraceptives in preventing unplanned pregnancies, reflecting the higher continuation rates of IUD acceptors. Although the availability of both methods clearly contributed to expansion of the programme, the demographic and administrative implications of initial choice of method, and the finding that pregnancy rates for pill users are not lower than for IUD wearers, suggest the need for more realistic counselling by clinic and field staff at the time of choice.
在锡兰计划生育项目开展的最初几年,对口服避孕药和宫内节育器的使用者进行了一项随访研究,以确定1968年一项政策决定的影响。该政策决定将口服避孕药的每个周期价格减半,并允许经过培训的现场助产士在医疗监督下进行非临床处方和分发避孕药丸。虽然避孕药的接受率有所提高,但研究结果表明持续使用率并未提高。总体而言,宫内节育器在预防意外怀孕方面比口服避孕药有效得多,这反映出宫内节育器使用者的持续使用率更高。虽然这两种方法的可获得性显然有助于该项目的扩大,但方法的初始选择所带来的人口统计学和行政管理方面的影响,以及避孕药使用者的怀孕率并不低于宫内节育器佩戴者这一发现,表明诊所和现场工作人员在选择时需要提供更现实的咨询服务。
