Internet access and use among homeless and indigent drug users in Long Beach, California.

There has been a growing interest in using the Internet to access a variety of populations for prevention education and health care. It is not clear that this is viable for homeless and other marginalized populations. The purpose of this study was to describe Internet access and use among a sample of homeless and indigent drug users. A brief questionnaire was developed to assess computer ownership, use, email, and Internet access and use. Participants were recruited through a community-based human immunodeficiency virus (HIV) prevention program. 265 participants completed the questionnaire. While 55% had ever used a computer in their lifetime, only 25% had ever owned a computer, 24% had ever had their own email account, 33% had access to a working computer in the last 30 days, 10% had sent or received email in the last 30 days, and 19% had surfed or accessed information on the Internet in the last 30 days. Logistic regression predicting lifetime use of a computer showed predictive factors of having completed high school (Odds Ratio [OR] = 4.5; 95% Confidence Interval [CI] = 2.41, 8.38) and number of days used amphetamines in the last 30 days, per 5 days of use (OR = 1.64; 95% CI = 1.18, 2.27). Inversely related were age, per 5 years of age (OR = 0.78; 95% CI = 0.65, 0.93) and number of days used marijuana in the last 30 days, per 5 days of use (OR = 0.97; 95% CI = 0.76, 0.99). Very low access and usage suggest that Internet-based public health education models be reexamined for this population. The association with amphetamine use may indicate a facilitating effect of amphetamine by heightening awareness and increasing wakefulness.

High incidence of new sexually transmitted infections in the year following a sexually transmitted infection: a case for rescreening.

BACKGROUND: Studies show 11% to 15% of women treated for Chlamydia trachomatis are reinfected 3 to 4 months after treatment, suggesting the need for rescreening. There is little information on infections among men, infections with Neisseria gonorrhoeae or Trichomonas vaginalis, or long-term follow-up. OBJECTIVE: To determine the incidence of new sexually transmitted infections during the year after a visit to a sexually transmitted disease (STD) clinic and associated risk factors. DESIGN: Secondary analysis of data from a randomized, controlled trial (RESPECT-2). SETTING: 3 urban STD clinics. PATIENTS: Sexually active patients enrolled in an HIV prevention counseling trial. MEASUREMENTS: Patient characteristics at the initial visit; behaviors during follow-up; and new infections with C. trachomatis, N. gonorrhoeae, or T. vaginalis (women only) detected during 4 scheduled return visits and any other interim visits. RESULTS: 2419 persons had 8129 three-month follow-up intervals. Among 1236 women, 25.8% had 1 or more new infections (11.9% acquired C. trachomatis, 6.3% acquired N. gonorrhoeae, and 12.8% acquired T. vaginalis); among 1183 men, 14.7% had 1 or more new infections (9.4% acquired C. trachomatis, and 7.1% acquired N. gonorrhoeae). Black persons and those with sexually transmitted infections at baseline were at highest risk for recurrent infection (adjusted odds ratio, 2.5 and 2.4, respectively). For persons infected at baseline, the risk for infection was high at 3 and 6 months (16.3 per 100 three-month intervals) and remained high at 9 and 12 months (12.0 per 100 three-month intervals). Most (67.2%) infections were diagnosed during study-related visits, and 66.2% of these patients reported no symptoms. LIMITATIONS: Because patients were recruited from STD clinics, results may not be generalizable. CONCLUSIONS: Men and women who receive diagnoses of C. trachomatis, N. gonorrhoeae, or T. vaginalis infections should return in 3 months for rescreening because they are at high risk for new asymptomatic sexually transmitted infections. Although single-dose therapy may adequately treat the infection, it often does not adequately treat the patient.

Prevalence of and associated risk factors for fluoroquinolone-resistant Neisseria gonorrhoeae in California, 2000-2003.

BACKGROUND: Rates of fluoroquinolone-resistant Neisseria gonorrhoeae (QRNG) are increasing worldwide and in California. METHODS: As a supplement to established surveillance, the investigation of QRNG in California included expanded surveillance in southern California, with in-depth interviews of patients (who had QRNG during the period of January 2001-June 2002) and a cross-sectional study of patients at 4 sexually transmitted diseases clinics with gonococcal isolates that underwent susceptibility testing (for the period of July 2001-June 2002). RESULTS: The rate of QRNG increased from <1% in 1999 to 20.2% in the second half of 2003. The 2001-2002 expanded surveillance demonstrated that 66 (4.9%) of 1355 isolates were resistant to fluoroquinolones; the majority of these infections occurred after August 2001. Cross-sectional analysis of 952 patients with gonorrhea revealed that the prevalence of QRNG varied geographically during 2001-2002, with the highest rate being in southern California (8.9%) and the lowest being in San Francisco (3.6%). The QRNG prevalence was 8.6% among men who have sex with men (MSM), 5.1% among heterosexual men, and 4.3% among women. Although risk factors for QRNG varied by clinic, multivariate analysis demonstrated independent associations with race/ethnicity, recent antibiotic use, and MSM. CONCLUSIONS: The emergence and spread of QRNG in California appeared to evolve from sporadic importation to endemic transmission among both MSM and heterosexuals. Monitoring of both the prevalence of and risk factors for QRNG infections is critical for making treatment recommendations and for developing interventions to interrupt transmission.

Efficacy of a booster counseling session 6 months after HIV testing and counseling: a randomized, controlled trial (RESPECT-2).

BACKGROUND: HIV counseling prevents sexually transmitted diseases (STDs), with most of the benefit accumulating in the first 6 months. STUDY: The authors conducted a multicenter, randomized, controlled trial of a 20-minute additional (booster) counseling session 6 months after HIV counseling compared with no additional counseling for prevention of STDs (gonorrhea, chlamydia, trichomoniasis). Participants were 15- to 39-year-old STD clinic patients in Denver, Long Beach, and Newark. RESULTS: Booster counseling was completed by 1120 (67.8%) of 1653 assigned to receive it. An incident STD during the 6 to 12 months after initial counseling (and within the 6 months after scheduled booster counseling) was detected in 141 of 1653 (8.5%) participants in the booster counseling group and 144 of 1644 (8.8%) in the no-booster group (relative risk, 0.97; 95% confidence interval, 0.78-1.22). Three months after booster counseling, sexual risk behaviors were reported less frequently by the booster group than the no-booster group. CONCLUSIONS: Booster counseling 6 months after HIV testing and counseling reduced reported sexual risk behavior but did not prevent STDs.
