| Anabolic Steroids
Anabolic steroids is the familiar
name for synthetic substances related to the male sex hormones
(androgens). They promote the growth of skeletal muscle (anabolic
effects) and the development of male sexual characteristics (androgenic
effects), and also have some other effects. The term "anabolic
steroids" will be used through-out this report because of its
familiarity, although the proper term for these compounds is "anabolic-androgenic"
steroids.
Anabolic steroids were developed in the late 1930s primarily to
treat hypogonadism, a condition in which the testes
do not produce sufficient testosterone for normal growth, development,
and sexual functioning. The primary medical uses of these compounds
are to treat delayed puberty, some types of impotence,
and wasting of the body caused by HIV infection
or other diseases.
During the 1930s, scientists discovered that anabolic steroids could
facilitate the growth of skeletal muscle in laboratory animals,
which led to use of the compounds first by bodybuilders and weightlifters
and then by athletes in other sports. Steroid abuse has become so
widespread in athletics that it affects the outcome of sports contests.
More than 100 different anabolic steroids have been developed, but
they require a prescription to be used legally in the United States.
Most steroids that are used illegally are smuggled in from other
countries, illegally diverted from U.S. pharmacies, or synthesized
in clandestine laboratories.
What are steroidal supplements?
In the United States, supplements such as dehydroepian-drosterone
(DHEA) and androstenedione (street name Andro) can be purchased
legally without a prescription through many commercial sources including
health food stores. They are often referred to as dietary supplements,
although they are not food products. They are often taken because
the user believes they have anabolic effects.
Steroidal supplements can be converted into testosterone (an important
male sex hormone) or a similar compound in the body. Whether such
conversion produces sufficient quantities of testosterone to promote
muscle growth or whether the supplements themselves promote muscle
growth is unknown. Little is known about the side effects of steroidal
supplements, but if large quantities of these compounds substantially
increase testosterone levels in the body, they also are likely to
produce the same side effects as anabolic steroids.
What is the scope of steroid abuse in the
United States?
Recent evidence suggests that steroid abuse among adolescents is
on the rise. The 1979 Monitoring the Future study, a NIDA-funded
survey of drug abuse among adolescents in middle and high schools
across the United States, estimated that 2.7 percent of 8th- and
10th-graders and 2.9 percent of 12th-graders had taken anabolic
steroids at least once in their lives. For 10th-graders, that is
a significant increase from 1978, when 2.0 percent of 10th-graders
said they had taken anabolic steroids at least once. For all three
grades, the 1979 levels represent a significant increase from 1971,
the first year that data on steroid abuse were collected from the
younger students. In that year, 1.9 percent of 8th-graders, 1.8
percent of 10th-graders, and 2.1 percent of 12th-graders reported
that they had taken anabolic steroids at least once.
Few data exist on the extent of steroid abuse by a significant increase
from 1978, when 2.0 percent of 10th-graders said they had taken
anabolic steroids at least once. For all three grades, the 1979
levels represent a significant increase from 1971, the first year
that data on steroid abuse were collected from the younger students.
In that year, 1.9 percent of 8th-graders, 1.8 percent of 10th-graders,
and 2.1 percent of 12th-graders reported that they had taken anabolic
steroids at least once.
Few data exist on the extent of steroid abuse by adults. It has
been estimated that hundreds of thousands of people aged 18 and
older abuse anabolic steroids at least once a year.
Among both adolescents and adults, steroid abuse is higher among
males than females. However, steroid abuse is growing most rapidly
among young women.
