We conducted a randomized controlled trial of a sexual risk-reduction intervention targeting non-injection drug users (NIDUs) and members of their drug-use/sexual networks (N=270). The intervention was based primarily on the social-influencing approach, and was delivered in four sessions. Sexual risk behaviors were examined at baseline, and 3, 6, 9, and 12 months after the completion of the intervention using the vaginal equivalent episodes (VEE), a weighted sexual risk behavior index. VEE scores decreased in both the active and control conditions in the first six months post-intervention and continued to decline in the control group. However, in the active condition, VEE scores increased after the nine-month assessment and approached baseline levels by the 12-month assessment. There was no evidence of significant differences in high-risk sexual behaviors between the intervention and control conditions. Future studies are needed to improve behavioral interventions in this population.
"Recent studies have demonstrated that the overlap of sexual partnership between IDUs and NIDUs may be an important clue to understanding the increased prevalence (Howard and Latkin 2006, Jenness, Neaigus, Hagan, Murrill and Wendel 2010). Although sexual-risk reduction interventions targeting NIDUs and their sexual networks are emerging (Castor et al. 2010), it is possible that routine and frequent HIV testing may additionally contribute to elucidating the elevated HIV prevalence among NIDUs. However, the factors related to HIV testing among NIDUs are not clearly understood. "
[Show abstract][Hide abstract] ABSTRACT: Abstract HIV testing services and research among drug users has largely focused on injection drug users (IDUs); yet noninjection drug users (NIDUs) are also at increased risk for HIV due to high-risk sexual behaviors and overlapping networks with IDUs. This study examined drug use, sexual risk, and social network characteristics associated with recent HIV testing (testing within past year) among NIDUs. Interviewer-administered questionnaires were conducted among 418 NIDUs and log-binomial regression models were used to identify correlates of recent HIV testing. Prevalence ratios (PR) with 95% confidence intervals (CI) were reported. Nearly 97% of NIDUs reported having ever been tested for HIV and most participants (85.7%) indicated testing for HIV within the past year. Factors independently associated with recent HIV testing were higher educational attainment (PR: 1.86; 95% CI: 1.03, 3.34) and networks to discuss health and medical services (PR: 1.84; 95% CI: 1.06, 1.20). A prior positive sexually transmitted infection was associated with decreased likelihood of recent HIV test (PR: 0.43; 95% CI 0.25, 0.74). Identifying specific social network characteristics may be effective in facilitating HIV testing and prevention strategies targeting NIDUs.

[Show abstract][Hide abstract] ABSTRACT: People with severe mental illness (SMI) may be at increased risk for several adverse health conditions, including HIV/AIDS. This disproportionate disease burden has been studied primarily at the individual rather than community level, in part due to the rarity of data sources linking individual information on medical and mental health characteristics with community-level data. We demonstrated the potential of Medicaid data to address this gap.
We analyzed data on Medicaid beneficiaries with schizophrenia from eight states that account for 66% of cumulative AIDS cases nationally.
Across 44 metropolitan statistical areas (MSAs), the treated prevalence of HIV among adult Medicaid beneficiaries diagnosed with schizophrenia was 1.56% (standard deviation = 1.31%). To explore possible causes of variation, we linked claims files with a range of MSA social and contextual variables including local AIDS prevalence rates, area-based economic measures, crime rates, substance abuse treatment resources, and estimates of injection drug users (IDUs) and HIV infection among IDUs, which strongly predicted community infection rates among people with schizophrenia.
Effective strategies for HIV prevention among people with SMI may include targeting prevention efforts to areas where risk is greatest; examining social network links between IDU and SMI groups; and implementing harm reduction, drug treatment, and other interventions to reduce HIV spread among IDUs. Our findings also suggest the need for research on HIV among people with SMI that examines geographical variation and demonstrates the potential use of health-care claims data to provide epidemiologic insights into small-area variations and trends in physical health among those with SMI.

[Show abstract][Hide abstract] ABSTRACT: We examined the impact of a combination of home environmental interventions and nurse case management services on total settled dust loadings and on allergen concentrations in the homes of asthmatic children. METHODS Using a randomized longitudinal controlled trial study design, we randomly assigned homes of asthmatic children in Milwaukee to either a control (n = 64) or an intervention (n = 57) group. Control group homes received a visual assessment, education, bed/pillow dust mite encasings, and treatment of lead-based paint hazards. The intervention group received these same services plus nurse case management that included tailored, individual asthma action plans, provision of minor home repairs, home cleaning using special vacuuming and wet washing, and integrated pest management. Dust vacuum samples were collected from measured surface areas of floors in the TV room, kitchen, and child's bedroom at baseline and at three-, six-, and 12-month follow-up visits. Dust loading (mass per surface area) is a means of measuring total dust and the total amount of allergen present.
For the intervention group, geometric mean dust loadings declined significantly from baseline (39 milligrams per square foot [mg/ft2]) to postintervention (11 mg/ft2) (p < 0.001). Baseline dust loading, treatment group, visit, and season were significant predictors of follow-up dust loadings. Mean post-intervention dust loadings were 72% higher in the control group. The total amount of allergen in settled house dust declined significantly following the intervention because total dust loading declined; the concentration of allergens in settled dust did not change significantly.
The combination of nurse case management and home environmental interventions promotes collaboration between health and housing professionals and is effective in reducing exposures to allergens in settled dust.
