CHAPTER 4
TEENAGE PREGNANCY AND ITS RESOLUTION
Sandra L. Hofferth
One major source of confusion in the literature dealing
pregnancy and childbearing is precisely the distinction between
pregnancy and its outcomes. People often say they're referring to
teenage pregnancy when they only beve information on births. Pregnancy
can be resolved in a number of ways, only one of which is a live birth
kept by the mother. However, in talking about the problems of teen
pregnancy, the problems that have been well-documented to date are
those associated with that one outcome--bearing and raising a child as
a teenager. Another set of confusions revolves around the process
which leads ultimately to childbearing and its implications for policy
and programs. For example, an agency may be interested in developing
a profile of young women at risk of teen childbearing to target them
for intervention. As discussed in earlier chapters, in order to become
a teen mother, a young woman must first become sexually active, next,
not use contraception or fail in its use in some way (including experi-
encing method failure), and, finally, once pregnant, decide to bear and
raise the child herself. There are several points at which a~terna-
tives present themselves. Some teens choose one way, others choose
another. Thus the agency has several possible points at which to tar-
get its interventions: at initiation of sexual activity, at contracep-
tive use, or, at the resolution of a pregnancy.
In this chapter some basic demographic description of the number
and rates of teen pregnancies, births and abortions are first presented
for the United States. Comparisons are drawn with Denmark, a country
with registers of health events. Statistics showing the actual way
pregnancies to O.S. teens are resolved are presented, followed by a
discussion of research that sheds light on the factors associated with
resolving a pregnancy one way rather than another. A summary and
conclusions section closes the chapter.

BACKGROUND
In 1984 there were 469,682 births to teenagers 15 to 19, 9,965
births to teens under 15. This represents a considerable decline in
births to teens over the decade, from a high of 656,000 in 1970. The
78

79
number of pregnancies rose slightly until 1980 and has declined
slightly since then. There were over a million pregnancies to teens
in 1984 (Table 3.1~.
However, the change in the absolute numbers of births and pregnan-
cies does not adequately indicate the incidence of teen pregnancy and
childbearing because it does not take into account changes in the
number of teen women. The number of teens rose during the 1970s,
leveling off in the mid 1970s and declining since 1979. Nor does it
take into consideration the number of women at risk, that is, the
number of women who are sexually active (see Hofferth et al., 1986~.
This is especially important for teenagers, only a portion of whom are
sexually active. Pregnancy ratesl per 1000 women 15 to 19 rose 9
per- cent between 1974 and 1984; however, because the proportion who
were sexually active also rose over the period, the pregnancy rates
per 1000 sexually active women 15 to 19 actually fell 8.7 percent
between 1974 and 1984.
What does this mean for individual women? The pregnancy rate in
1984 was 231 per 1000 sexually active women. This means that in 1984,
23 percent of sexually active teenagers would have become pregnant.
This figure, however, only indicates the proportion of teens who would
become pregnant in any one year. A more interesting figure is the pro-
portion of young women who would ever become pregnant before reaching
age 20. That is, what is the chance that a young woman would become
pregnant as a teenager? Although this probability has been estimated
using survey data, since abortions are underestimated in such data, the
estimates of pregnancy will be low. Better estimates are obtained from
reporting data such as those collected by the Centers for Disease Con-
trol and the Alan Guttmacher Institute. Based on such data it was
estimated that in 1981 about 44 percent of young women will become
pregnant before reaching age 20, 40 percent of white and 63 percent of
black women (Forrest, 1986; Table 3.3~.
Of course, this estimate, too, is rather crude, since among those
young women are some who became sexually active very early in their
teens, others who became sexually active very late and others who were
still virgins at age 20. The data that are most helpful in showing
what the actual risk of pregnancy is among those who are sexually
active, breaks the probability down by the length of time since first
intercourse and uses a life table methodology to estimate the risk of
conception within the first two years after first intercourse (Zabin,
1979; Koenig and Zelnik, 1982~. Data collected in 1976 (Zabin, 1979)
indicate that within the first three months 9 percent of white and 14
percent of black teenage women will have experienced a first premarital
pregnancy (Table 3.7~. By the end of the first year that figure has
risen to 17 percent for whites and 27 percent for blacks, and by the
end of two years, 30 percent of whites and 37 percent of black teen-
agers will have experienced a first premarital pregnancy. Data from
1979 (Koenig and Zelnik, 1982) suggest a slight increase in the proba-
bility of pregnancy during the first two years after first intercourse
between 1976 and 1979, with 33 percent of white teenagers and 43 per-
cent of black teenagers experiencing a first premarital pregnancy with
OCR for page 78
80
in two years after first intercourse (Table 3.5~. me probability of
a first pregnancy is strongly affected by two factors--the age at first
intercourse and the use of contraception (Tables 4.6 and 4.8~. Preg-
nancy rates are much for those older at first intercourse and for those
who always used a contraceptive method. There was little difference in
pregnancy between those who used a prescription and non-prescription
methods, as long as they always used it (Koenig and Zelnik, 1982~.
THE RESOLUTION OF TEEN PREGNANCIES
What happens to these one million teenage pregnancies? Many more
young women under 20 become pregnant than bear a child, almost twice
as many. In 1982 the total births to teenagers 15 to 19 represented
47 percent of the total number of pregnancies (abortions plus births
plus miscarriages [Table 3.11~.
Table 3.2 shows how pregnancies in 1982 were divided: 40 percent
of the pregnancies were aborted, and 13 percent miscarried; thus
slightly under half, 47 percent, resulted in a live birth. The 47
percent which were live births are divided as follows: 13 percent
were postmaritally conceived births, 11 percent were premaritally con-
ceived but born postmaritally, and 23 percent were born out-of-wedlock
(estimates from Table 3.1 and O'Connell and Rogers, 1984~.
The resolutions to a premarital pregnancy considered here are
abortion versus having a live birth, marriage versus non-marriage, and
adoption versus keeping the child.
Live Birth versus Abortion
The proportion of teenage pregnancies that ended in a live birth
decreased over the past decade (Table 3.1~. The number of teen preg-
nancies has risen, but because the number of abortions has risen even
faster, the number of births has been declining. Both the number of
abortions and the abortion rate increased by 50 percent between 1974
and 1980. The percent of teenage pregnancies terminated by abortions
climbed rapidly, increasing from 27 percent to 40 percent between 1974
and 1980. Since 1980, the abortion rate and ratio have remained level.
Birth rates for all women have remained fairly level; rates for those
sexually active beve declined. (Table 3.1~.
Of course, it is difficult to interpret these figures without some
comparison. What is a high level of pregnancy, of births, of abortions
for teenagers? Unfortunately, there are only limited international
data on abortions, especially by age of the woman. The United States
has a high abortion rate for young women compared to western European
countries (Jones et al., 1985; Henshaw and O'Reilly, 1983~. The United
States also leads in the percent of abortions to teenagers (Tietze,
1983; Bachu, 19831. In spite of the large number of abortions, births
to United States teens are also high, relative to other countries (AGI,
1981; Jones et al., 19853.

81
Denmark is a good country with which to compare the United States.
Levels of sexual activity among teenagers are actually higher in Den-
mark than in the U.S. (Rasmussen and David, 1981~. Abortion laws were
liberalized there about the same time as in the United States--the
early 1970s. Most important, Denmark has an excellent abortion re-
porting system. With a unique identifying number for each person and
a centralized information gathering system, the data on abortion in
Denmark are among the most complete in any nation.
Pregnancy rates in the United States have been about twice the
level of Denmark for the past decade (David et al., 1982; Table 3.11.
In both countries the pregnancy rates increased initially after
liberalization of abortion, but levels in Denmark returned to those
prior to liberalization, while those in the United States continued to
rise. As a result, rates of abortions and births in the U.S. in 1980
and 1981 are considerably higher than in 1970. Abortion rates in both
countries rose. However, while they have leveled off in Denmark, they
have continued to rise in the United States.
The rapid increase in pregnancy and abortion rates in the U.S.
during the 1970s was due to the rapid increase in sexual activity over
the same period. Apparently, levels of sexual activity rose dramati-
cally in Denmark during the 1960s (Rasmussen and David, 1981~; thus by
the time abortion was legalized in both countries, sexual activity had
begun to level off in Denmark at a higher level. In contrast, the
major increase in sexual activity in the U.S. occurred dur ing the
1970s, with a leveling off during the early 1980s (see discussion,
Chapter 1~. As Table 3.1 showed, pregnancy rates among those sexually
active actually showed a decline between 1974 and 1984.
Two valuable lessons from these data and from a recent study of
five western European nations fJones et al., 1986) are that 1) high
levels of sexual activity do not necessarily result in high pregnancy
rates, given adequate use of contraception, and 2) low birth rates do
not necessarily imply high abortion rates; they may simply imply low
pregnancy rates. Low abortion rates and low birth rates are com-
patible.
Among teens, the proportion of pregnancies terminated by abortion
is higher in Denmark than in the United States, primarily due to the
high abortion ratio among 15 to 17 year old Danes (David et al., 1982~.
15 to 17 year old United States teens are much more likely to bear
their babies than Danish 15 to 17 year olds. Jones et al. (1985) also
found that in each of 5 developed nations they investigated, that 15-17
year olds were much more likely to abort a pregnancy than 18-19 year
olds: the difference was smallest in the U.S. This suggests substan-
tial differences between United States and other countries in choice
of resolution for unplanned pregnancies, differences which will be
pursued a little later.
Marriage
One way of resolving an out-of-wedlock teenage pregnancy is by
marrying. So far all teenage pregnancies have been lumped together.
OCR for page 78
82
In fact, some 13 percent of all teenage births are postmaritally con-
ceived (Table 3.2), and such births are not generally considered to be
problematic. In 1980 only 5 percent of abortions to teens 15 to 19
(about 2 percent of all pregnancies) were to married women (Henshaw et
al., 1985~. Assuming that abortions indicate that a pregnancy was un-
intended, it can be inferred that most pregnancies to married women are
intended. Zeloik (1979) found that 53 percent of first births to women
who were married were unintended. If to the proportion of postmarital
births are added a proportion of the miscarriages and a small propor-
tion of the abortions, it can be seen that that between 15 and 20 per-
cent of all pregnancies to women under 20 occur to married women. The
remainder, 80 to 85 percent, are premarital pregnancies.
Earlier, it was pointed out that about 24 percent of sexually
active teenagers age 14 become pregnant each year. However, this does
not tell us how many teenagers age 14 become pregnant before they reach
20 or marry. According to 1979 survey data (Zelnik and Kantner, 1980),
16 percent of all metro teenage women 15 to 19 had ever experienced a
premarital pregnancy, double that of 1971. Of those sexually active,
33 percent had ever experienced a premarital pregnancy, a small in-
crease since 1971. Thus, when control is introduced for the increase
in sexual activity over the decade of the 1970's, the incidence of pre-
marital pregnancy has not changed very much. The major reason for the
large apparent increase in premarital pregnancy is the increase in
sexual activity. There was an increase in premarital pregnancy among
sexually active white teens, but not among black teens. The lack of
increase among blacks is probably due to underreporting of abortion.
Thus premarital pregnancy has increased, but not as much among those
sexually active as it appears from the increase in the population of
teenagers. Data from the 1982 National Survey of Family Growth show a
slight decline in premarital pregnancy among teenagers between 1979
and 1982, although the difference is probably not statistically sig-
nificant. In 1982 14 percent of all teen women 15 to 19 had ever
experienced a premarital pregnancy, compared with 16 percent in 1979.
Of those premaritally sexually active, 30 percent experienced a pre-
marital pregnancy.
These figures substantially underestimate the true proportion of
teenagers who become pregnant before they reach age 20 or marry because
abortions are substantially underreported in surveys--by as much as 50
percent. Some subgroups report more accurately than other subgroups
(Mosher, 1985~. Unmarried black teenage females are the least likely
to accurately report their abortions, with unmarried white teenage
females only slightly more accurate. Older married white females are
the most accurate reporters of their own abortions. Since accurate
pregnancy estimates depend on accurate abortion reports, the reports
of pregnancy obtained from surveys will be lower than those estimated
on the basis of nationally collected data from organizations such as
the Centers for Disease Control and the Alan Guttmacher Institute.
Recent calculations from the latter (Forrest, 1986; Table 3.3) suggest
that based on 1981 data about 40 percent of white teenagers 15-19 and
63 percent of black teenagers would experience a first pregnancy
before reaching age 20.

83
The increase in premarital pregnancy over the decade of the 1970s
was not due to an increased wontedness of pregnancy. Table 3.6 shows
that the proportion of premaritally pregnant teens who were unmarried
at resolution who wanted the pregnancy actually declined between 1971
and 1979 for whites and blacks alike, and the proportion using contra-
ception increased (Zelnik and Kantner, 1980; Table 4.4~. Of course,
premaritally conceived but marital births, which constitute about 11
percent of teen pregnancies, are excluded here. However, since the
proportion who marry to resolve a premarital pregnancy also declined,
the proportion who wanted a pregnancy probably also declined for all
premaritally pregnant teen women.
Contraceptive use generally improved between 1971 and 1982. A
smaller proportion reported never using contraception, a higher pro-
portion reported always using it. A larger proportion used contra-
ception at first intercourse and at last intercourse in 1982 than in
1971. Unfortunately, Table 3.4 shows that the percentage of pre-
maritally sexually active teen women who ever experienced a premarital
first pregnancy rose in all contraceptive use statuses 1976-79, except
for those who used contraception at first intercourse but not always
(Zelnik and Kantner, 1980~. The largest increase was among never
users, but increases also occurred among those who always used contra-
ception. The authors attribute this increase in pregnancy, parti-
cularly among the youngest teens, to sharply increased frequency of
intercourse and to decreased reliance on the most effective methods of
contraception (Koenig and Zelnik, 1982~. Data are not yet available
from the 1982 NSFG to see whether pregnancy rates continued to increase
among contraceptive users as well as non-users. We suspect they have
not, since pregnancy rates have been declining.
Adoption
Data from three surveys of young women (Bachrach, 1985) show that
the proportion of teenage women whose first pregnancy ended in a first
premarital birth and who gave their baby up for adoption declined in
the 1970s between 1971 and 1976 and leveled off at a low level between
1976 and 1982 (Table 8.1~. Eighteen percent of white teenagers re-
ported having terminated parental rights in 1971, 2 percent of blacks.
By 1976 only 7.0 of whites and no blacks reported having given up a
baby for adoption. By 1982 7.4 percent of whites and fewer than 1 per-
cent of blacks reported having given up a child for adoption. Based
on data from the National Survey of Family Growth, the estimated
annual number of unrelated adoptions declined to a low in 1976 and has
been gradually increasing since then.
Agency data support survey evidence which showed declining adoption
placements from the early to the mid-1970s (Bachrach, 1985~. Legal
abortion became an alternative to adoption for many young women who had
an unintended pregnancy and who would have adopted if abortion were not
available. It has been argued that the reduced social stigma attached
to unwed pregnancy caused a shift away from adoption as an alternative
OCR for page 78
84
to childbirth. The subsequent apparent increase in adoption may be a
response to the substantial demand for babies to adopt as well as a re-
sponse to the many concerns about the ethics of abortion. This is just
speculation, since there is no research that would allow us to shed
light on these changes. Just documenting the changes that have occur-
red is a difficult task.
RESEARCH
Factors Associated with Resolution of Premarital Teen
Pregnancies: Delivering the Baby
Once a teenager is pregnant, what factors are associated with
whether she has an abortion or carries the pregnancy to term and de-
livers the baby? One study found that the younger the teen at concep-
tion, the more likely she was to carry the pregnancy to term (Zelnik
et al., 1981~. In this study 13 to 16 year olds were more likely to
have a live birth compared with 17 to 19 year olds comparable on other
factors. This is supported by data from another study, which found
that of those 13 to 19, the 16 to 17 year olds were most likely to have
a live birth. However, national statistics on abortion ratios do not
support these findings. The true explanation may be the underreporting
of abortions in sample surveys of teenagers, which is likely to be most
serious for the younger teens. An underreporting of abortions would
increase the apparent proportion who carry pregnancies to term. Thus,
due to underreporting of abortion, it is not clear whether factors are
related to choice of abortion or birth or to whether abortion is re-
ported. This is a serious problem for analytic study of abortion
using sample surveys.
The birth year of the teenager is important. At a given age, ear-
lier birth cohorts are more likely than more recent cohorts to have a
live birth (Zelnik et al., 1981~.
Young women are more likely than in the past to resolve a premari-
tal pregnancy by abortion (Table 4.5~. White teenagers were 1.3 times
and black teenagers 2.5 times more likely to have an induced abortion
in 1978 than in 1972. Although in the early 1970s black teenagers had
a lower likelihood of using abortion to resolve pregnancy, according
to these abortion ratios, after 1974 the abortion ratios are similar
or slightly higher for blacks than whites. Since abortion data appear
to be underreported more for blacks (Zelnik and Kantner, 1980), the
difference in levels between blacks and whites may be underestimated.
The abortion ratio appears to have levelled off after 1980, according
to national figures (Table 3.1~.
The black-~hite difference in likelihood of abortion varies by age.
Among young teenagers the ratio of abortions to births is lower for
blacks than whites (Table 4.6~. However, this difference declines such
that ratios are similar for 19 year olds. Among older women, ratios
are higher for blacks than for whites.
OCR for page 78
85
One source of difference is the age at which abortions and preg-
nancies are measured. The Ezzard et al. {1982) study (Table 4.5)
adjusted age to age at conception. This is particularly important at
younger ages. Only a third of women who became pregnant before age 15
were still under 15 at delivery, while three-fourths of those obtaining
abortion were still under 15 at the time of abortion (Henshaw et al.,
1985~. Thus differences between the figures will be sharpest at
youngest ages.
Zelnik et al. (1981) found that the more religious a young women,
the more likely she is, once pregnant, to bear the child. Another
study using data from a small study of health providers in Ventura
County California found white Catholics to be less likely to have a
live birth, once pregnant than either white non-Catholics or Hispanic
Catholics (Eisen et al., 1983~. Emus the particular religious affili-
ation appears less important in the decision than the strength of
religious conviction.
Teens living in the East or North central United States or in an
urban area are more likely to have a live birth, once pregnant, than
those in other regions or in non-urban areas (Zelnik et al., 1980~.
The most important family factor associated with delivering a baby
versus aborting a pregnancy is parental education. The higher the
education of parents, the lower the likelihood that a teenager, once
pregnant, will have a live birth (Zeloik et al., 1980~. The mother's
opinion of abortion is important, with girls whose mothers are more
favorably disposed toward abortion less likely to have a live birth
(Eisen et al., 1983~.
Peer environment is important. The more positive a likely a young
pregnant girl is to have a live birth (Eisen et al., 1983~. In addi-
tion, girls who know a single teen mother are more likely to have a
live birth (Eisen et al., 1983~.
Among the most important factors affecting the outcome of the preg-
nancy was whether the pregnancy was wanted. Girls who said they wanted
the pregnancy were much more likely to have a live birth than those who
didn't (Zelnik et al., 1980~. Of course, this measure of wontedness
was obtained after the resolution of the pregnancy; ex-post facto
rationalization may be measured here.
Beliefs about abortion and birth are important. Having favorable
attitudes toward and beliefs about abortion prior to the event were
associated with a lower probability of having a live birth (Eisen et
al., 1983) and with a positive abortion intention (Smetana and Adler,
1979~. Intention to have an abortion was associated with a lower
probability of having a live birth (Smetana and Adler, 1979~. Positive
beliefs about having a child were associated with a low intention to
have an abortion. Finally, women choosing either abortion or birth be-
lieved others wanted them to follow this alternative, with women
intending abortion most motivated to comply with friends' expectations
(Smetana and Adler, 1979~.

86
Among the most important factors associated with choice of preg-
nancy resolution are expectations and academic achievement. High
school dropouts and those not enrolled in school, those with a low
grade point average, and those with low educational expectations have
been found more likely, once pregnant, to have a live birth (Eisen et
al., 1983; Leibowitz et al., 1980; Devaney and Hubley, 1981~.
Two studies have looked at the relationship between receipt of
AFDC and pregnancy resolution decision. Moore and Caldwell looked at
the probability of abortion, marriage and out-of-wedlock birth among
premaritally pregnant U.S. women aged 15 to 19 in 1971, data collected
by Kantner and Zelnik in the National Survey of Young Women. Control-
ling for a number of individual characteristics, such as education of
the father, wontedness of pregnancy, importance of religion and race,
they found the probability of abortion to be significantly lower in
states having relatively generous AFDC benefit levels (Moore and
Caldwell, 19771.
Eisen et al. (1983) and Leibowitz et al. (1980) examined a group
of 299 pregnant teenagers who went to health providers in Ventura
County, California between 1972 and 1974 for assistance in terminating
a pregnancy or for prenatal care. The teens were interviewed twice,
once prior to abortion or delivery and a second time six months after
the resolution of the pregnancy. The authors hypothesized that young
women who received state support would be more likely to choose de-
livery than girls who were self-supporting. They found that both
receiving financial aid f ram the family and receiving financial aid
from the state (AFDC) were associated with choosing delivery {Eisen et
al., 1983; Leibowitz et al., 1980~. However, more young women than
those currently living in welfare families would be eligible for wel-
fare if they did give birth; thus the study really measures the effect
of actual receipt of welfare benefits, rather than their availability.
Factors Associated with Marriage Before Birth (Legitimation)
Young women are less likely now than in the past to resolve a pre-
marital pregnancy by marrying. The proportion of women pregnant before
marriage who resolved a premarital pregnancy by marrying dropped by 50
percent between 1971 and 1979 for both whites and blacks {Zelnik and
Kantner, 1980~. The data show very little additional change between
1979 and 1982, although the data are not completely comparable, and the
total number of pregnancies is underreported (Horn, 19853.
If we look only at pregnancies that end in a live birth, we see
that of the total first births to white and black teenagers, the pro-
portion conceived outside of marriage has risen, and the proportion
premaritally conceived but legitimated before birth rose then declined
to about the same initial level {O'Connell and Rogers, 1985~. As a
result, the proportion born out of wedlock rose sharply.
Two studies have examined factors associated with whether a pre-
maritally pregnant teenager who subsequently had a birth married prior
OCR for page 78
87
to that birth: Zeloik et al. (1981) used data from the National Survey
of Young Women in 1971 and 1976. They found that (among those who were
premaritally pregnant and gave birth) white teenagers, those from a
higher socioeconomic status background and those who wanted the baby
were more likely to marry before bearing the child. me second study
used the data from Ventura County, California (Eisen et al., 1983~.
m ey found that (among those who carried to term) the only factor that
discriminated between those who married before the birth and those who
didn't was whether the family had been receiving financial aid from
the state. Those girls whose families had been receiving financial
aid from the state during pregnancy were less likely to marry than
those who had not been receiving such assistance (Eisen et al., 1983~.
Factors Associated with Bearing an Out-of-Wedlock Child
The resolution many people are interested in is that of bearing a
child out-of-wedlock compared with all other options. The previous
analyses have explored the decisions in temporal sequence: that is,
they have looked at, first, the decision to abort or carry a premarital
pregnancy to term, and, second, the decision to marry or not marry
before birth among those who carry to term. Several analyses have
studied this decision as a joint one with three choices: 1) abortion,
2) marriage and birth, and 3) bearing an out-of-~edlock child. The
results of studies viewing the decision this way do not differ from
the results of studies using paired comparisons only, but this approach
allows simultaneous comparison among all alternative resolutions.
Young women who are black, who live in a metropolitan area, whose
parents are of low educational levels, who are young at first concep-
tion, and who live in a large family are more likely to bear a child
out-of-wedlock than to either abort or marry (Eisen et al., 1983;
Leibowitz et al., 1980; Devaney and Hubley, 1981; Zelnik et al., 1980~.
In addition, Leibowitz et al., 1980 and Eisen et al., 1983 found teens
living in families receiving financial aid from the state to be more
likely than their peers to bear an out-of-wedlock child. In contrast,
using 1971 data from the National Survey of Young Women, Moore and
Caldwell (1977) found no relationship between level of AFDC benefits
and having an out-of-wedlock birth. The latter found a negative rela-
tionship between AFDC acceptance rates and the probability of having
an out-of-wedlock birth. That is, young women in states with high
acceptance rates were less likely to have an out-of-wedlock birth
(Moore and Caldwell, 1977~. There was no significant association be-
tween AFDC benefit levels and acceptance rates and the probability of
marrying before the birth (Moore and Caldwell, 19771.
Adoption
Only a few studies beve compared teens who have made adoption plans
with teens who have kept and parented their children. These are sum-
marized in Resnick (1984~. The results suggest that teenagers who make
adoption plans are similar to those who have abortions but different
from those who take on parenting responsibilities. The former tend to
OCR for page 78
88
be older, to have more parental influence and less male partner influ-
ence, and to be of higher socioeconomic status. Parenting teens tend
to be younger, to have less schooling, to not be attending school and
to come from non-intact homes. Thus those who make adoption plans
tend to have more prospects for the future. In addition, they were
reared in smaller towns and cities and have more traditional attitudes
about abortion and family life (Resnick, 1984~.
Recent data from the 1982 National Survey of Family Growth (Bach-
rach, 1985) show that teenagers under 18, whose parents have had some
college, whose baby was born before 1973, and who were living with both
parents at age 14 were more likely than other teenagers to place the
child for adoption if they had a premarital birth.
Two recent studies (Kallen, 1984; Resnick, 1984) are funded by the
Office of Adolescent Pregnancy Programs to look more closely at the
factors affecting the decision of unmarried pregnant teens to make an
adoption plan. At this writing no results are yet available.
Factors Associated with Decision Satisfaction
It is obvious that no one decision is the "right" decision for all
adolescents, since the circumstances differ among individuals. How-
ever, researchers have found some regularities in the extent to which
individuals express satisfaction or dissatisfaction about the decisions
they have made in resolving their pregnancies. A study of a Danish
sample found that the degree of satisfaction with the decision depended
on the firmness of the decision in the first place. Of those who had
made a firm decision to abort soon after learning about pregnancy, 94
percent said that the decision was correct 6 months later. Of those
who were not so certain, 72 percent said that the decision was correct
6 months later (David et al., 1982~. Of those whose decision was firm,
59 percent experienced relief afterward, compared with 28 percent of
the less firm. None of the Danish women expressed feeling of guilt
over the decision.
A study of United States teen women (Rosen, 1983) found that the
more alternatives considered, the greater the dissatisfaction with the
decision. This probably reflects greater uncertainty as to what to do,
and is consistent results from the Danish study (David et al., 19821.
The Eisen and Zellman (1984) study of pregnant teens in Ventura
County, California found no significant difference in decision satis-
faction 6 months after pregnancy resolution by type of decision made,
age or ethnic group. Nearly all--80 percent--expressed satisfaction
in their decision. There were some differences in degree of satisfac-
tion depending on the decision made. Among teenagers who chose abor-
tion, those with better educated mothers, who had advocated abortion
for themselves, who were more approving of abortion in general and who
used contraception more consistently following abortion were more
satisfied (Eisen and Bellman, 19841. Among teens who chose single
motherhood, those not enrolled in formal schooling during the six

months after birth were more likely to be satisfied with the decision,
as were those with maternal support for single parent status. Among
teens who married, none of the variables utilized significantly dit-
ferentiated those who were satisfied with their decision from those
who weren't.
Interesting and Controversial Issues
Three issues are worth looking at further. The first issue is the
relationship between age and pregnancy resolution. Young teenagers in
the United States have a very high probability of bearing the child,
once pregnant, compared to older teenagers or teenagers in other coun-
tries (Jones et al., 1985~. Data from the Danish study (David et al.,
1982) show abortion ratios (abortions divided by births plus abortions)
to IS to 17 year olds that are twice those of U.S. 15-17 year olds.
Three-quarter of the pregnancies to young Danish teens are terminated
by abortion, compared with 40 percent of those to young U.S. teens.
Abortion ratios for 18 to 19 year olds are very similar in the U.S.
and in Denmark. Results from the National Survey of Young women sug-
gested that, net of other factors, girls younger at conception are
more likely than older teens to carry a pregnancy to term. Although
the differences are exaggerated because of the underreporting of
abortion at younger ages, it could be expected that abortion would be
higher at younger ages than at older ages, as shown by the Danish
sample, since few young women wanted these pregnancies.
Thus the lack of difference by age in the United States is of in-
terest. Why are 15 to 17 year old pregnant teens in the United States
so much more likely to bear a child than comparable teens in a country
such as Denmark and other countries? Why are they as likely to bear a
child as their 18 to 19 year old peers in the U.S.?
The second important issue is that of race differences in pregnancy
resolution. The chapter has emphasized differences between blacks and
whites, but conclusions about race differences in pregnancy resolution
based on analyses of survey data are of necessity weak because of dif-
ferential reporting of abortion by race in those data sets. The best
information on subgroup characteristics come from the Centers for
Disease Control, AGI, and from the National Center for Health Statis-
tics and they are good. However, such data do not provide the depth
of information needed to explore causal factors in decision-making.
Another problem is whether to use abortion rates or ratios. The abor-
tion ratio is higher among blacks than whites for all ages except the
teen years (Table 4.63. During the teen years, the ratio of induced
terminations of pregnancy to live births is higher for whites than for
blacks. However, if you look at the abortion rate (Table 4.4) the
rate is higher for non-whites than for whites at all ages. This is
because the pregnancy rate for non-whites is also higher. Thus, in
this case, using the abortion rate would lead to a completely
different and erroneous conclusion about black-white differences.
Analysts need to choose the appropriate measure for their purposes.

One reason for the differences between blacks and whites in abor-
tion is that blacks appear to use abortion for spacing or to end child-
bearing more than to postpone a first birth. Sixty-five percent of
abortions to whites occurred to childless women, compared to 39
percent of abortions to blacks (Table 4.71.
However, there is another problem with the data. Figures are often
based on age of the woman at pregnancy outcome. Since birth occurs
nine months and abortion approximately 3 months after a conception, a
proportion of the young women who conceived (and who eventually bore a
child) at the same time as those who conceived and who eventually ter-
minated the pregnancy through abortion would be one year older at out-
come. Thus the event (pregnancy) occurred at the same age, but this
would not be reflected in the statistics. Adjusting the data to age
at conception would take care of this problem, but would also alter
the number of births and abortions, especially at younger ages. Thus
the Ezzard et al. (1982) study (Table 4.5) shows almost no black-white
difference in abortion ratios when abortions and births are adjusted
to age at conception. This raises an important issue of comparability
of measures across studies. The Alan Guttmacher Institute teas moved
toward reporting ratios adjusted to age at conception. The other
organizations that report abortion statistics do not yet do so {the
Centers for Disease Control and the National Center for Health
Statistics).
A third interesting issue is that of repeat abortion. In 1980
one-third of O.S. aborters had previously had an abortion {Tietze,
1978; Henshaw and O'Reilly, 1983: Table 7~. The figure is smaller for
teenagers, as could be expected, since they have not had as much time
to have one, let alone two abortions. NCHS data suggest that 12 per-
cent of abortions to 15 to 17 year olds, and 22 percent of abortions
to 18 to 19 year olds are repeat abortions (Table 4.7~. There are two
potential reasons for concern. First, there may be negative effects of
abortion on later childbearing and subsequent pregnancies. Second,
there may be (over~utilization of abortion as substitute for contracep-
tion.
Are there negative effects of abortion on later childbearing and
subsequent pregnancies? This literature has been reviewed in Strobino
(in this volume) and Hogue (1982~; the reader is referred to those
sources. After adjusting for the fact that abortions performed on
teenagers are performed later in pregnancy, which is somewhat more
risky, rates of mortality and morbidity from abortion are somewhat
lower for teenagers than for adult women. There is only one instance
in which teenagers appeared to be at higher risk of injury than adults.
Teenagers appeared to be at higher risk of cervical damage than older
women (Cates et al., 1983; Cates, 1981~.
Although there is little evidence that having had one prior abor-
tion increases a woman's risk of miscarriage, premature birth or
bearing a low birth weight baby, there is some evidence that having
had multiple abortions may increase this risk, although, again, the
results of several different studies do not agree (Levin et al., 1980;
Chung et al., 1982~.

Is abortion overutilized as a substitute for contraception? me
concern that abortion is becoming a substitute for contraception does
not seem founded. Although in 1971 the percentage of teen women who
had a premarital second pregnancy was higher 2 years after the outcome
of the first premarital pregnancy for those who had an abortion than
for those who had a birth, by 1979 the figures were reversed. In 1979
teen women who had terminated their premarital first pregnancy by abor-
tion were less likely to have a second pregnancy within two years than
those who had carried the first pregnancy to term (Koenig and Zelnik,
1982~. Tietze (1978) argued that the increasing number of repeat
abortions reflects the increasing number of women who have had a first
abortion and are, therefore, at risk of having a second abortion. This
appears to be born out by a recent study that shows few differences
between women obtaining a first and those obtaining a repeat abortion
(Berger et al., 1984~. Those obtaining a repeat abortion were older,
less likely to be married and more tolerant of legal abortion than were
women having a first abortion. Hey had intercourse more frequently
and they were more likely to have been contracepting when they became
pregnant. They did not differ on type of method used or on any other
demographic, psychological or attitudinal measures. Finally, results
from a 1982 national survey show that fewer than one half of 1 percent
of women exposed to the risk of unintended pregnancy, who did not use
contraception, mentioned the availlability of abortion as a reason for
nonuse (Forrest and Henshaw, 1983~.
SUMMARY AND CONCLUSIONS
How women choose to resolve their pregnancies has become one of the
major factors determining the number and rate of births to teens. Only
about half of all pregnancies to teens end in a live birth. Yet only
a very small amount of research has been conducted on this important
issue. One important issue that researchers have just begun to address
is whether miscarriage and abortion have psychological, social, health,
familial, educational, economic or other consequences for adolescents
and for their families. A few studies have focused on short term
psychological effects, but there are no long term studies. The many
studies of health effects that have been conducted have found little
negative impact on health (Hogue et al., 1982~.
One major question that several researchers have addressed is why
individual women choose one form of resolution to a pregnancy over
another. The major studies in this area use two data sets: the
National Surveys of Young Women (1971, 76, 79) and a study of 299
women in Ventura County, California in 1972-74. These are the only
studies to provide multivariate evidence on the issue, and they are
the only studies to have focused on the resolution of premarital teen
pregnancies (as distinguished from postmarital teen pregnancies). It
is important to make this distinction. Few people consider maritally
conceived pregnancies problematic, although, among young teenagers,
they may be. Research suggests that a premaritally pregnant teen is
more likely to give birth rather than obtain an abortion if she wanted
the pregnancy, is of lower socioeconomic status, is unfavorably dis

posed to abortion, has lower aspirations and educational expectations,
receives parental financial assistance, currently lives in a family
that receives public assistance, and lives in a state with higher AFDC
benefit levels. These results are based on a very limited set of
studies, however, and all these studies suffer from underreporting of
abortion.
Among those who give birth, those who are of lower socioeconomic
status, who are younger, and who are black are less likely to marry
than their peers.
Two types of data are needed: 1) Vital statistics data that can
provide national estimates of abortion (and, as a result, pregnancies)
by age and, simultaneously, by race/ethnicity, and 2) Survey data that
not only provide reasonable estimates of abortion but also contain
variables that could be used to test hypotheses about relationships
among variables both at one point and over time. At the present time
there are no national reporting requirements for abortions. Abortion
data are presently estimated from three sources: a national survey of
providers by the Alan Guttmacher Institute, counts of characteristics
of abortion patients obtained by the Centers for Disease Control and
counts of abortions obtained in 12-13 reporting states by the National
Center for Health Statistics. National estimates of abortions in sur-
vey data can be obtained from the National Survey of Young Women (1971,
1976) and the National Survey of Young Women and Young Men (1979), the
National Survey of Family Growth, Cycle ITI (1982), and the National
Longitudinal Survey of Youth, Ohio State University (1979-1985~. Un-
fortunately, all these surveys have documented substantial under-
reporting of abortions, so they should be used cautiously until we
have a better understanding of the bias this introduces into our
analyses.
Note
1 Pregnancies = Births and abortions plus miscarriages. Accurate
abortion data are needed to calculate the number of pregnancies.
Abortion was legalized in the U.S. in 1973. Prior to this year, the
annual number of abortions in the U.S. could only be estimated.
Therefore, 1974 was selected as a comparison year since it is probably
the first full year with good abortion statistics.
