Abstract：
:This paper presents a secondary analysis of 3419 Norplant users from 11 countries throughout Asia, Africa and Latin America. The main objective was to identify the menstrual problems associated with a high risk of early discontinuation of Norplant use. Eligible participants were divided into two groups: those who continued use (n = 2667) for the first 3 years and those who discontinued use because of bleeding or pain (n = 752) during the first 3 years of use. Menstrual characteristics of the women were compared between groups using a logistic regression model with generalized estimating equations. Flow duration of more than 7 days, excessive amount of flow, dysmenorrhea and intermenstrual bleeding for more than 7 days were associated with a significant risk of discontinuation. The highest risk was observed in association with flow duration of more than 7 days (adjusted odds ratios of 1.85, 2.01 and 2.20 at 1, 2 and 3 years, respectively). The appropriate management of prolonged or excessive bleeding, namely by continuous counseling, is essential for successful Norplant use.
