Correlates of trichomonas prevalence among street-recruited, drug-using women enrolled in a randomized trial

Health outcomes associated with crack-cocaine use: Systematic review and meta-analyses

BACKGROUND

Crack-cocaine use is prevalent largely in socio-economically marginalized populations in the Americas. Its use has been associated with diverse health outcomes, yet no recent or systematic reviews of these exist.

METHODS

A systematic review of health outcomes associated with crack-cocaine use was performed, using MEDLINE, Scopus, Web of Science, CINAHL, PsycINFO, and LILACS up to October 2016. Search terms included crack-cocaine and health outcome-related keywords, targeting peer-reviewed studies on quantified health outcomes associated with crack-cocaine use. Random effects meta-analyses produced pooled odds ratios. Levels of evidence for major results were assessed using the GRADE approach. A review protocol was registered with PROSPERO (CRD42016035486).

RESULTS

Of 4700 articles returned, 302 met eligibility criteria, reporting on health outcomes for 14 of 22 ICD-10 chapters. Conclusive evidence and meta-analyses showed positive associations between crack-cocaine use and blood/sexually transmitted diseases (HIV and hepatitis C virus, others); moderate evidence and meta-analyses supported associations with neonatal health, and violence. There were mixed associations for mental and other health outcomes, yet insufficient evidence to perform meta-analyses for many categories (e.g., mortality). Most underlying research was of limited or poor quality, with crack-cocaine commonly assessed as a secondary covariate.

CONCLUSIONS

Crack-cocaine use was associated with a range of health outcomes, although it was unclear if there was direct causal impact, interactions between risk factors, or external drivers of both crack-cocaine use and outcomes. Rigorous epidemiological studies are needed to systematically assess health outcomes of crack-cocaine use and underlying pathways, also to inform evidence-based interventions.

Factors associated with syphilis seroreactivity among polydrug users in Northeast Brazil: A cross-sectional study using Respondent Driven Sampling

BACKGROUND

The burden of sexually transmitted infections (STIs), such as syphilis, is higher in low-income countries, with serious consequences and profound impact on sexual and reproductive health and human immunodeficiency virus (HIV) spread. Syphilis prevalence tend to be higher among people who misuse drugs than in the general population.

OBJECTIVE

To assess syphilis and associated factors among polydrug users (PDU) in the city of Salvador, Northeast Brazil.

METHODS

A cross-sectional study was conducted in 10 Brazilian cities between September and November 2009 using Respondent Driven Sampling (RDS). Participants answered an Audio Computer-Assisted Self Interview (ACASI) and were rapid tested for HIV and syphilis. We performed multivariable regression models for correlates of syphilis on Stata 10.0. Estimates were weighted by the inverse size of the individual social network size and homophily.

RESULTS

Mean age was 29.3 years (range: 18-62), 74.0% were males, and 89.8% were non-white. Syphilis prevalence was 16.6%. Females (adjwOR:2.14; 95%CI:1.09-4.20), individuals over 29 years old (adjwOR:4.44; 95%CI:2.41-8.19), those who exchanged sex for money or drugs (adjwOR:3.51; 95%CI:1.84-6.71), "No/low" self-perceived risk of HIV infection (adjwOR:5.13; 95%CI:1.36-19.37), and having nine or less years of education (adjwOR:2.92; 95%CI:1.08-7.88) were associated with syphilis.

CONCLUSION

One of the most pressing needs for syphilis prevention/control is the availability of rapid point-of-care diagnostic tests and treatment. Interventions should be tailored to PDU needs and their multiple burdens as shown in the present study, that may contribute to future studies aiming to better understand the relationships between drug use and syphilis.

Correlates of Trichomonas vaginalis Among Middle Age and Older Adults Who Use Drugs

BACKGROUND

Recent studies have reported high rates of Trichomonas vaginalis among middle age and older adults. Though trichomoniasis risk factors in this age cohort remain largely unknown, illicit drug use has been associated with increased incidence of sexually transmitted infections (STIs). The number of mid-older adults using illicit drugs has increased significantly in recent years suggesting the need to understand the relationship between drug use and STIs in this age cohort.

OBJECTIVES

This study examined the relationship between drug use, sexual-risk behaviors, and biologically confirmed T. vaginalis in a sample of mid-older and younger adults who reported recent drug use.

METHODS

The cross-sectional design examined the relationship between past 6-month drug use, sexual risk-behaviors, and PCR-confirmed T. vaginalis in 264 adults age 18-64 who were recruited from Baltimore, Maryland. These relationships were also explored in the age-stratified sample among those 18-44 years ("younger") and individuals 45+ years ("mid-older").

RESULTS

Trichomoniasis prevalence did not differ significantly between younger (18.8%) and mid-older (19.1%) adults. Mid-older adults that tested positive for T. vaginalis were more likely to have used marijuana and crack in the past 6 months. Among younger adults, there were no associations between trichomoniasis and past 6-month drug use and sexual-risk behavior.

CONCLUSIONS/IMPORTANCE

Age- and drug-related immune decline is hypothesized to contribute to increase susceptibility to T. vaginalis in mid-older adults. Broad screening for trichomoniasis, particularly among older adults who are often not regarded as at risk for STIs, is needed to control this often asymptomatic infection.

Chlamydia trachomatis infection among female inmates at Briman prison in Saudi Arabia

BACKGROUND

Chlamydia trachomatis infection is the most common sexually transmitted infection (STI) in the western countries; its prevalence in the conservative Muslim population of Saudi Arabia is not known, but it is generally believed to be low. This study is the first to investigate the prevalence of and risk factors for C. trachomatis infection in the high-risk group of female inmates at Briman Prison in Jeddah.

METHODS

The inmates were interviewed using a pre-designed questionnaire, and their urine samples were tested for C. trachomatis infection by real-time PCR assay.

RESULTS

The overall prevalence of C. trachomatis infection was 8.7% in the study population. The ≤25 age group was predominantly affected, with an average prevalence of 16.6%. Two out of five (2/5, 40%) Yamani, (4/33 12.1%) Indonesian, (3/33, 9.1%) Somalian and (2/26, 7.7%) Ethiopian inmates were positive for infection. None of the Saudi inmates (0/14) were positive for infection. Among the studied variables, only age was significantly associated with the infection rate. The other variables (marital status, nationality, religion, employment status, education level, nature of the offense committed, knowledge about protection from STIs, and knowledge about condom use and the purpose of condom use) did not show a significant correlation with Chlamydia infection.

CONCLUSIONS

The overall prevalence of C. trachomatis infection was within the range published by other reports in similar prison settings in developed countries. The results indicate the need for a countrywide screening and treatment program for all inmates at the time of entry into prison.

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

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.

Three city feasibility study of a body empowerment and HIV prevention intervention among women with drug use histories: Women FIT

BACKGROUND

New intervention models are needed for HIV prevention among drug-using women.

METHODS

The Women Fighting Infection Together (Women FIT) feasibility study enrolled 189 women in three U.S. cities (Providence, New York, Philadelphia) with drug-using histories, who also reported risky sexual behavior. Eligible women had participated previously in a yearlong study of HIV Counseling and Testing (HIV-CT) and limited case management. Two thirds of the sample were black, most were unemployed, and about two thirds reported prior or current crack use. Women were randomized into two groups. In one group, women participated in a manualized, four-session, peer-led, interactive group intervention that stressed body knowledge, woman-initiated HIV/sexually transmitted infection (HIV/STI) prevention, including a focus on women's health (reproductive health screening, sexual violence, self-breast examination, STI signs, symptoms), which aimed to increase comfort with and pride in their bodies. Control group women received HIV-CT enriched by female condom counseling. Outcomes included study retention, session attendance and ratings, changes in knowledge, and use of protection methods.

RESULTS

The study successfully retained 95% of the participants for a 2-month follow-up. Positive assessments from participants and peer leaders exceeded preset thresholds for success. Pre-post changes in body knowledge (p < 0.0001) and protection methods knowledge (p < 0.01) was greater among the intervention women than the control women.

CONCLUSIONS

The body empowerment model deserves further elaboration in interventions focusing on women at high risk of HIV/STI acquisition.

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.

Dual HIV risk and vulnerabilities among women who use or inject drugs: no single prevention strategy is the answer

PURPOSE OF REVIEW

This article examines the dual HIV and sexually transmitted infection (STI) risk behaviors engaged in by women who use or inject drugs; the individual, social, and structural drivers of HIV and STI risk; prevention strategies; and the implications for multilevel, combined, sex-specific HIV prevention strategies.

RECENT FINDINGS

Women who use or inject drugs, especially female sex workers, are at dual risk for HIV, the hepatitic C virus (HCV), and other STIs. In countries with HIV prevalence higher than 20% among injecting drug users (IDUs), female IDUs have slightly higher HIV prevalence than male IDUs. Women who use or inject drugs face multilevel drivers that increase their vulnerabilities to HIV, HCV, and STIs. Despite advances in behavioral HIV prevention strategies for this population, most prevention studies have not sufficiently targeted dyadic, social, and structural levels. Few recent advances in biomedical HIV prevention have focused on women who use drugs and their unique needs.

SUMMARY

HIV prevention strategies and services need to address the unique and multilevel drivers that increase the vulnerabilities to HIV, HCV, and STIs among women who use drugs including those who engage in sex work. Scaling-up and improving access to multilevel and combined HIV prevention strategies for these women is central to combating the HIV epidemic.

Prevalence and predictors of sexually transmitted infections in hazardously-drinking incarcerated women

Incarcerated women are at high risk for sexually transmitted infections. Left untreated, these infections can have severe adverse health effects. In this study the authors present prevalence rates of trichomonas, chlamydia, and gonorrhea, and factors related to having a sexually transmitted infection in a sample of 245 hazardously-drinking incarcerated women who reported heterosexual intercourse in the previous 3 months. Vaginal swabs were collected following the self-report baseline assessment. Participants averaged 34.0 (±8.8) years of age; 174 (71.3%) were non-Hispanic Caucasian, 47 (19.3%) were African-American, 17 (7.0%) were Hispanic, and 6 (2.5%) were of other racial or ethnic origins. Twenty-three percent of participants tested positive for chlamydia, trichomonas, or gonorrhea. Being African-American, more frequent sex with a casual partner, and reporting more than one male partner were significantly positively related to sexually transmitted infection, while more frequent sex with a main partner was inversely related. Due to the high rates of infection in this population, jail admission provides a public health opportunity to access a concentrated group of sexually transmitted infectious women. Sexually transmitted infection testing targeted at specific demographic factors, for instance younger age, will miss infected women. Risky sexual partnerships, as well as the benefit of maintaining stable main partnerships may be important topics during sexually transmitted infection prevention interventions.

Incidence of sexually transmitted infections among hazardously drinking women after incarceration

INTRODUCTION AND BACKGROUND

At the time of incarceration, women have a high prevalence of sexually transmitted infections (STI). In the months after community release, women remain at high risk for new infections. This study assessed the rates and predictors of incident chlamydia, gonorrhea, and trichomoniasis in a sample of hazardously drinking women after incarceration.

METHODS

Self-reported behavioral data were collected from 245 incarcerated women. Vaginal swabs were collected at baseline, and 3- and 6-month time points and tested for chlamydia, gonorrhea, and trichomoniasis. Treatment was provided for all positive tests.

RESULTS

Participants' mean age was 34.1 years of age; 175 (71.4%) were Caucasian, 47 (19.2%) were African American, 17 (6.9%) were Hispanic, and 6 (2.4%) were of other ethnic origins. The STI incidence rate was estimated to be 30.5 (95% confidence interval, 21.3-43.5) new infections per 100 person-years. Number of male sex partners reported during follow-up was a significant (z = 2.16; p = .03) predictor of STI; each additional male sex partner increased the estimated hazard of STI by 1.26.

CONCLUSION

Incarcerated women who are hazardous drinkers are at high risk for STI in the months after their return to the community. In addition to testing and treatment during incarceration, post-release rescreening, education, partner treatment, and follow-up are recommended.
