This paper is a report of a epidemiological study of the use effectiveness of four kinds of IUDS: the stainless steel uterine cavity shaped device (UCD), the stainless steel single ring (SSR), MLCu 250, and the TCu220C in Jiangsu Province, China. 711 parity one breast-feeding rural women aged 22-32 who were 3-9 months post partum were recruited to participate in the study. They were randomly assigned for insertion of one of the four kinds of IUDs on the 8th day after starting the menstrual period. Regular follow-up was conducted after the IUD insertion. The cumulative discontinuation rate at 28 months was the lowest for UCD (18.03%). The rate for MLCu 259 was 27.6, for TCu 220c was 28.01%, and SSR was the highest (50.6%), and by far the worse (p.01). Removal due to excessive menstrual bleeding or cramping was the highest for TCu 220c (13.83%) and the lowest for MLCu 250 (2.81%) (p.01). Rural women are usually subjected to the heavy physical labor of farming, and breast-feeding women generally have thinner and softer uterine walls. The horizontal arm of TCu 220c may produce more irritation to the uterine wall than MLCu 250. The conclusion of the study is that for rural farming women and breast-feeding women, UCD and MLCu would be better types of IUDs than TCu 220c and SSR.
