Michigan Youth Risk Behavior Survey

SEXUAL BEHAVIOR
Fact
Sheet
The Michigan Youth Risk Behavior Survey (YRBS) is part of a nationwide surveying effort led by the
Centers for Disease Control and Prevention (CDC) to monitor students’ health risks and behaviors in six
categories identified as most likely to result in adverse outcomes. These categories include unintentional
injury and violence, tobacco use, alcohol and other drug use, sexual behaviors that contribute to unintended
pregnancy or disease, dietary behaviors, and physical inactivity. High response rates allow results of the
2005 YRBS to be generalized to all Michigan students in grades 9-12.
Of Vital Concern:
The National
Perspective
2005 Survey Results
Over half of all high school students have
never had sexual intercourse. Among
those who have had sexual intercourse, over a quarter
were abstinent the previous three months (Figure 1).

Adolescent Sexual Behavior
Percentage of MI H.S. Students
Age at first intercourse and number of
sexual partners is associated with
increased risk for unwanted pregnancy
and other sexually transmitted diseases,
including HIV infection. Latex condoms,
when used consistently and correctly,
are highly effective in preventing
transmission of HIV and can reduce the
risk of other sexually transmitted
diseases (STDs). Gonorrhea rates are
highest among females between the
ages of 15 and 19 (715.8 cases per
100,000) and males between the ages
of 20 and 24 (589.7 per 100,000).
Through 2002, 13% of persons
diagnosed with HIV/AIDS were 13-24
years old at diagnosis. The percentage
of high school students who ever had
sexual intercourse decreased from 54%
in 1991 to 47% in 2003, while condom
use among currently sexually active
students increased significantly from
46% in 1991 to 63% in 2003. In 2000,
73% of senior high schools taught HIV
prevention education in a required
health education course.

Significantly more twelfth
grade students than ninth and
tenth grade students reported
having sexual intercourse,
multiple partners,1 and
recent2 sex (Figures 2 and 3).
Among those students who
recently had sex, ninth and
tenth graders were more likely
than eleventh and twelfth
graders to have used a
condom. However, eleventh
and twelfth grade students
were more likely than ninth
graders to have used birth
control pills (Figure 3).
