A Diagram of the Social-Ecological Conditions of Opioid Misuse and Overdose.

The United States is experiencing a crisis of opioid misuse and overdose. To understand the underlying factors, researchers have begun looking upstream to identify social and structural determinants. However, no study has yet aggregated these into a comprehensive ecology of opioid overdose. We scoped 68 literature sources and compiled a master list of opioid misuse and overdose conditions. We grouped the conditions and used the Social Ecological Model to organize them into a diagram. We reviewed the diagram with nine subject matter experts (SMEs) who provided feedback on its content, design, and usefulness. From a literature search and SME interviews, we identified 80 unique conditions of opioid overdose and grouped them into 16 categories. In the final diagram, we incorporated 40 SME-recommended changes. In commenting on the diagram's usefulness, SMEs explained that the diagram could improve intervention planning by demonstrating the complexity of opioid overdose and highlighting structural factors. However, care is required to strike a balance between comprehensiveness and legibility. Multiple design formats may be useful, depending on the communication purpose and audience. This ecological diagram offers a visual perspective of the conditions of opioid overdose.

Active Drug-Using Women Use Female-Initiated Barrier Methods to Reduce HIV/STI Risk: Results from a Randomized Trial.

UNLABELLED: Background. We tested an original, woman-focused intervention, based on body empowerment, and female-initiated barrier methods, including the female condom (FC) and cervical barriers. Methods. Eligible women were >= 18 years of age, HIV seronegative, and active drug users, reporting 30% or greater unprotected sex acts. Both controls (C) and intervention (I) participants received enhanced HIV/STI harm reduction counseling. I participants underwent 5 additional weekly group sessions. We compared change in frequency of unprotected vaginal intercourse across arms at 12 months. Results. Among 198 enrolled women, over 95% completed followup. Two-thirds were African-American; most of them used crack, had a primary partner, and reported sex exchange. In paired t-tests from baseline to followup, the frequency of unprotected vaginal sex dropped significantly for I (primary P < 0.00, nonprimary P < 0.002) and C (primary P < 0.008, nonprimary P < 0.000) arms with all partners. The difference in change across arms was of borderline significance for primary partner (P = 0.075); no difference was seen for nonprimary partner (P = 0.8). Use of male condom and FC increased with both partner types over time, but more consistently among I women. CONCLUSION: The "value-added" impact of the intervention was observed mainly with primary partners. Body knowledge with routine FC counseling should be incorporated into interventions for drug-using women.

Basic body knowledge in street-recruited, active drug-using women enrolled in a "body empowerment" intervention trial.

BACKGROUND: Drug-using women remain at high risk for HIV infection. Female condoms (FC) have proven potential and cervical barriers have promise to reduce HIV risk; their effective use may be boosted by familiarity and confidence about female anatomy. Women with high levels of crack cocaine use were assessed for their knowledge about reproductive anatomy, HIV/STI risk, as well as cancer screening behaviors. METHODS: Women were recruited for a randomized trial of a behavioral intervention via mobile vans in Philadelphia known for high crack use and sex exchange. Knowledge and behavioral data on 198 women were collected via interviewer-administered questionnaire. Women were randomized into control (n=99) and intervention (n=99) arms. Five weekly, small-group, intervention sessions stressed "body empowerment" and teaching use of female-initiated barrier methods. Follow-up body knowledge data were collected at 12 months. Changes in and correlates of body knowledge were analyzed and compared. RESULTS: Most participants were African-American (66%); their mean age was 39.6 years. At baseline, 44% of the sample erroneously believed women have sex and urinate from the same place; 62% erroneously believed that tampons could get lost in the abdominal cavity. Only 27% knew douching increased STI transmission risk; only 10% knew condoms reduce cervical cancer risk. At follow-up, overall body knowledge improved substantially, across both arms. Race was associated with high body knowledge at baseline but not at follow-up. CONCLUSIONS: Knowledge favoring use of women-initiated methods and cervical cancer prevention was very low in this hard-to-reach sample. Body knowledge improved substantially with enhanced voluntary counseling and testing (VCT) as well as the women-focused intervention. Body knowledge education must be targeted and tailored to drug-using women.

HIV incidence rates and risk factors for urban women in Zambia: preparing for a microbicide clinical trial.

OBJECTIVES: A preparedness study was conducted to evaluate the suitability of sites and populations following the same study procedures intended for a larger scale microbicide efficacy trial. In the process the study evaluated human immunodeficiency virus (HIV) incidence, prevalence, and risk profiles for HIV-acquisition among young women in urban Zambia. METHODS: Women aged 16 to 49 years were screened for participation in the study that involved HIV/sexually transmitted infection testing and the assessment of sexual behavioral characteristics. Two hundred thirty-nine eligible women were enrolled and followed up for 12 months. RESULTS: Baseline HIV prevalence at screening was 38.7% (95% CI: 34.2%-43.3%). The highest age-specific prevalence of HIV was 54.1% (95% CI: 46.3%-61.8%) seen in women aged 26 to 34 years. HIV incidence was 2.6% per 100 woman years. Pregnancy rates were high at 17.4 per 100 woman years (95% CI: 12.2-24.1). CONCLUSION: It was concluded that our general population sample, characterized by high HIV prevalence and ongoing incidence rates despite receiving regular risk reduction counseling and free condoms qualifies for future microbicide studies.A microbicide preparedness study conducted in Lusaka, Zambia found high HIV prevalence and appreciable HIV incidence in a population of women in an urban setting.
