This paper presents the findings of a study of K. C. Chan, Research Officer of the Family Planning Association of Hong Kong, whose purpose was to determine whether IUD retention rates could be increased by home visits to acceptors. Concern with this problem has mounted in many countries where the IUD is the main contraceptive method offered and where very high removal rates have led to low retention rates. Graphs, statistical data, and narrative material indicate that reassurance visits have very little long term effect on IUD acceptors and do not lead to significant reduction in the number of removals. The additional services of home visits, as offered in this study, were a heavy, time-consuming output and consequently considered a procedure too costly to be adopted. Also included in the paper are two further reports: An Experimental Population Education Program in Rural India and Use of the Agent System in Seoul. The first is a proposal for an educational program relating aspects of the population problem to the lives of students in their immediate environment. The second describes an agent system for recruiting IUD acceptors and evaluates the first nine months of such a program. (BL)
