Risk factors for Chlamydia among young women in a northern california juvenile detention facility: implications for community intervention.
OBJECTIVE
Chlamydia infections are increasing in California, with rates highest in young women aged 15 to 24. Juvenile detention facilities are important venues for screening high-risk youth who may not otherwise access care. We, therefore, sought to identify risk factors for urogenital chlamydia among young women in a county juvenile detention facility between 2002 and 2005.


METHODS
With the state Chlamydia Screening Project (ClaSP), young women booked into the county detention facility were offered urine-based screening for urogenital chlamydia. Demographics, sexual history, and behavioral risk factors were self-reported through questionnaires completed during specimen collection.


RESULTS
Nine hundred and thirty-nine young women were screened for chlamydia. The 5% positivity rate remained steady over the 33-month study. Vaginal sex was reported by 82% of women, oral sex by 50%, and anal sex by 30%. Only 9% reporting anal sex always used condoms. In multivariate analysis, little distinguished those with urogenital chlamydia. Women from the southern region of the county (adjusted odds ratio, 3.5; 1.4-8.7) and surrounding urban centers (3.7; 1.2-11.4) had higher odds of infection, as did those with 2 to 3 lifetime partners (3.2; 1.2-8.2)-although there was no linear relationship between partner number and infection. Those who had been in drug/alcohol treatment had lower odds of infection (0.1; 0.01-0.6).


CONCLUSIONS
Our findings support universal chlamydia testing of young women detainees. The high prevalence of unprotected anal sex highlights an important modifiable HIV risk behavior in these adolescents. Risk factors reported here should inform the integration of prevention and treatment services in correctional settings and substance abuse treatment centers.
