Abstract
The objective of the analysis reported here was to examine risk factors for early discontinuation of Norplant implant use due to perceived menstrual problems. Cox's proportional hazard regression model was used to calculate adjusted hazard ratios that would reflect the relationship of selected subject characteristics to the risk of early discontinuation due to perceived menstrual problems. Approximately 13% of the study population discontinued for perceived menstrual problems. At the end of year 2, the gross cumulative life table discontinuation rate for perceived menstrual problems was 9.4 per 100 women and it rose to 16.4 per 100 women at the end of year 5. Women in this study were significantly more likely to discontinue Norplant implant use due to perceived menstrual problems if they had a higher eduction level (>12 years), had used no contraceptives in the month before Norplant implant insertion, or had a relatively long average duration of menstrual flow at admission. Identifying potential risk factors such as these may help providers to counsel and prepare women to use the Norplant implant method.
