Less than one-half of a national sample of 20-37-year-old women survey
ed in 1991 report having been aware of the hormonal contraceptive impl
ant within the year following its approval by the U.S. Food and Drug A
dministration; there is considerable variation between groups of women
in levels of awareness and in knowledge of the implant's attributes.
Nearly one-third of the women surveyed say they intend to use such a m
ethod in the future. Subgroups with the greatest potential interest in
using this method are young women, single women, those who already ha
ve a child and those who would like to postpone their next birth for s
everal years or want to have no more children. Women who are using coi
tal methods of contraception and those not using any method are more l
ikely than others to express interest in using the implant. Interest i
n using the implant also increases with knowledge of the characteristi
cs of this contraceptive method.
