Purpose: The purpose of this study tvas to determine whether teenage g
irls who had been pregnant were more likely to engage in other risk or
problem behaviors than girls who had had sexual intercourse without b
ecoming pregnant. Methods: The 1993 Ohio Youth Risk Behavior Survey wa
s administered to a random sample of 2461 high school students. A subs
et of 592 girls (mean age 16.1 +/- 1.1 years, 69.2% Caucasian, 24.1% A
frican-American, 2.4% Hispanic, 4.3% other) reported sexual activity (
SA) on the anonymous survey. Demographic factors plus risk and problem
behaviors were compared between 98 girls who had been pregnant and 49
4 girls who had never been pregnant using Chi-square analysis. Risk an
d problem behaviors were classified into four distinct groups: recent
risk behaviors, age of onset of behavior, lifetime behavior, and gener
al behavior. Variables which were univariately significant at p < 0.15
were considered in one of four stepwise multiple logistic regression
models based on behavior type, with demographic factors considered in
all four models. The final logistic regression model was developed usi
ng variables which were significant at p < 0.01. Variables which were
significantly associated with pregnancy were summarized as odds ratios
(OR) and 99% confidence intervals (CI); these ORs were adjusted for t
he effects of the other variables in the model. Results: Pregnancy was
more common in girls of color than in Caucasian girls (OR 99% and CI,
2.09, 1.06-4.11) and in older girls than in younger girls (1.52, 1.12
-2.08). Among SA girls, weapon carrying in the past 30 days (4.06, 1.7
5-9.42) was significantly associated with pregnancy, whereas alcohol u
se in the past 30 days (0.37, 0.18-0.76) was less likely to be associa
ted with pregnancy. The risk of pregnancy increased 1.75 times (1.26-2
.43) for each additional sexual partner. Girls who had tried cocaine w
ere 4.88 times (1.40-16.95) more likely to have been pregnant, and the
risk of having been pregnant increased 1.43 times (1.14-1.80) for eac
h additional year of SA. Past history of sexually transmitted disease
(3.50, 1.28-9.55) was associated with increased pregnancy risk. Conclu
sions: Girls who had been pregnant also had engaged in other risk beha
viors, including recent weapon carrying and cocaine use. A history of
previous sexually transmitted diseases plus increasing numbers of part
ners add to the risk of pregnancy. Counseling and educational efforts
should continue to identify teens at risk both to prevent pregnancy an
d to decrease associated risks. (C) Society for Adolescent Medicine, 1
