Kh. Seal et al., Risk of hepatitis B infection among young injection drug users in San Francisco: opportunities for intervention, WEST J MED, 172(1), 2000, pp. 16-20
Objective To compare the demographic characteristics and risk behaviors for
hepatitis B infection among injection drug users younger than 30 years wit
h those aged 30 or older and to evaluate participants' knowledge, attitudes
, and experiences of infection, screening, and vaccination against hepatiti
s B virus. Design A systematic sample of injection drug users not currently
in a treatment program were recruited and interviewed at needle exchange p
rograms and community sites. Participants 135 injection drug users younger
than 30 years and 96 injection drug users aged 30 or older. Results Injecti
on drug users younger than 30 were twice as likely as drug users aged 30 or
older to report having shared needles in the past 30 days (36/135 [27%] vs
12/96 [13%]). Injection drug users younger than 30 were also twice as Like
ly to report having had more than two sexual partners in the past 6 months
(80/135 [53%] vs 29/96 [30%]). Although 88 of 135 (68%) young injection dru
g users reported having had contact with medical providers within the past
6 months only 13 of 135 (10%) had completed the hepatitis B vaccine series
and only 16 of (13%) perceived themselves as being at high risk of becoming
infected with the virus. Conclusion Few young injection drug users have be
en immunized even though they have more frequent contact with medical provi
ders and are at a higher risk for new hepatitis B infection than older drug
users. Clinicians caring for young injection drug users and others at high
risk of infection should provide education, screening, and vaccination to
reduce an important source of hepatitis B infection.
