This study examines the phenomenon of contraceptive risk-taking, which
is the nonuse of contraception by women who are sexually active, fert
ile and not pregnant or trying to become pregnant. Based on a survey s
ample of low-income women in their childbearing years who had not rece
ived family planning care or advice from a doctor or clinic for at lea
st three years, the study analyzed demographic predictors of contracep
tive risk-taking and also compared levels of contraceptive knowledge a
nd pregnancy histories of noncontraceptors versus barrier contraceptor
s. Contraceptive risk-taking was found to be higher for minority women
, for parous women, for those age 30 and younger, and for those whose
knowledge of the fertility cycle is incorrect, but risk-taking was fou
nd to be unrelated to the women's marital status. Noncontraceptors wer
e less knowledgeable concerning contraceptive methods and substantiall
y more likely to have had previous unwanted pregnancies due to nonuse
of contraception, suggesting that current contraceptive risk-taking pr
obably represents a relatively enduring feature of reproductive behavi
or for a subgroup of the medically undeserved low-income population.
