Early experience with the contraceptive use of depot medroxyprogesterone acetate in an inner-city clinic population.
There are few data on the experience of American women with the injectable depot medroxyprogesterone acetate (DMPA) since its recent approval by the Food and Drug Administration for contraceptive use in the United States. An exploratory study was conducted using chart reviews and telephone interviews of 261 women who initiated DMPA use between December 1992 and June 1994 at either a hospital-based (48%) or community-based (49%) clinic in New York City. Most DMPA users were single (70%), had had at least one birth (88%), had had at least one abortion (67%) and had ever practiced contraception (75% of those with available data). Life-table DMPA continuation rates were 63% at six months and 42% at 12 months and were not affected by the users' age, marital status, pregnancy history, clinic site or proximity of residence to the clinic. Among adults, the risk of DMPA discontinuation was highest during the three-month period following the second injection, while among adolescents, this risk increased throughout the duration of use. The most commonly reported reasons for method discontinuation were side effects, primarily menstrual irregularities (30%) and weight gain (24%).
