This study examines the extent to which transition from current use to past use is associated with method-specific beliefs using data from two rounds of a prospective longitudinal study collected from married women ages 15-39 years from Nairobi and Homa Bay Counties in Kenya. Information on fertility preferences, contraceptive behavior, method-related beliefs on six modern contraceptive methods and Calendar data were collected. Data analysis involved both single and multiple decrement life-table analysis. The twelve-month discontinuation rate for all methods was 36.5%, and the probability of method switching during the same period was 16.9%. The most common method specific beliefs reported included method causes infertility, it is unsafe to use a method for a long time without break, interference with menstruation and side effects. Method related concerns and beliefs contributed to nearly 52% of the overall discontinuation rate. The findings call for improved family planning counseling and quality of care.
