Context: Researchers have examined the age of partners of young women at fi
rst intercourse and of young women who have given birth, but little is know
n about the age of partners of young women in current sexual relationships
or young women who have had an abortion.
Methods: Data from the 1995 National Survey of Family Growth (NSFG) were us
ed to examine age differences between women and their current partner and w
omen's use of contraceptives at last intercourse, by marital status and by
the age difference between women and their partner. Data from the NSFG and
the 1994-1995 Alan Guttmacher Institute Abortion Patient Survey with supple
mental information from other sources, were used to estimate 1994 pregnancy
rates for women by their age and marital status, according to the age diff
erence between the women and their partner.
Results: Among all sexually active women aged 15-44, 10% had a partner who
was three or more years younger, 52% a partner who was within two years of
their age, 20% a partner who was 3-5 years older, and 18% a partner who was
six or more years older. In contrast, 64% of sexually active women aged 15
-17 had a partner within two years of their age, 29% a partner who was 3-5
years older, and 7% a partner who was six or more years older. Among women
younger than 18, the pregnancy rate among those with a partner who was six
or more years older was 3.7 times as high as the rate among those whose par
tner was no more than two years older. Among women younger than 18 who beca
me pregnant, those with a partner who was six or more years older were less
likely to have an unintended pregnancy (70%) or to terminate an unintended
pregnancy (21%) than were those whose partner was no more than two years o
lder (82% and 49%, respectively). Among women younger than 18 who were at r
isk of unintended pregnancy 66% of those who had a partner who was six or m
ore years older had practiced contraception at last sex, compared with 78%
of those with a partner within two years of their own age. Young women who
were Catholic and those who had first had sex with their partner within a r
elatively committed relationship were less likely to be involved with a man
who was six or more years older than were young women who were Protestants
and those who first had sex with their partner when they were dating, frie
nds or had just met. Young women who had ever been forced to have sex were
twice as likely as those who had not to have a partner who was 3-5 years ol
der.
Conclusion: Although the proportion of 15-17-year-old women who have a much
older partner is small, these adolescents are of concern because of their
low rate of contraceptive use and their relatively high rates of pregnancy
and birth. Research is needed to determine why some young women have relati
onships with an older man, and how their partner's characteristics affect t
heir reproductive behavior.
