Comparing injecting and sexual risk behaviors of long-term injectors with new injectors: A meta-analysis

Incarceration history is associated with HIV infection among community-recruited people who inject drugs in Europe: A propensity-score matched analysis of cross-sectional studies

AIMS

We measured the association between a history of incarceration and HIV positivity among people who inject drugs (PWID) across Europe.

DESIGN, SETTING AND PARTICIPANTS

This was a cross-sectional, multi-site, multi-year propensity-score matched analysis conducted in Europe. Participants comprised community-recruited PWID who reported a recent injection (within the last 12 months).

MEASUREMENTS

Data on incarceration history, demographics, substance use, sexual behavior and harm reduction service use originated from cross-sectional studies among PWID in Europe. Our primary outcome was HIV status. Generalized linear mixed models and propensity-score matching were used to compare HIV status between ever- and never-incarcerated PWID.

FINDINGS

Among 43 807 PWID from 82 studies surveyed (in 22 sites and 13 countries), 58.7% reported having ever been in prison and 7.16% (n = 3099) tested HIV-positive. Incarceration was associated with 30% higher odds of HIV infection [adjusted odds ratio (aOR) = 1.32, 95% confidence interval (CI) = 1.09-1.59]; the association between a history of incarceration and HIV infection was strongest among PWID, with the lowest estimated propensity-score for having a history of incarceration (aOR = 1.78, 95% CI = 1.47-2.16). Additionally, mainly injecting cocaine and/or opioids (aOR = 2.16, 95% CI = 1.33-3.53), increased duration of injecting drugs (per 8 years aOR = 1.31, 95% CI = 1.16-1.48), ever sharing needles/syringes (aOR = 1.91, 95% CI = 1.59-2.28) and increased income inequality among the general population (measured by the Gini index, aOR = 1.34, 95% CI = 1.18-1.51) were associated with a higher odds of HIV infection. Older age (per 8 years aOR = 0.84, 95% CI = 0.76-0.94), male sex (aOR = 0.77, 95% CI = 0.65-0.91) and reporting pharmacies as the main source of clean syringes (aOR = 0.72, 95% CI = 0.59-0.88) were associated with lower odds of HIV positivity.

CONCLUSIONS

A history of incarceration appears to be independently associated with HIV infection among people who inject drugs (PWID) in Europe, with a stronger effect among PWID with lower probability of incarceration.

Prevalence and associates of non-fatal overdose among people who inject drugs in Saveh, Iran

Background

As a public health issue, non-fatal overdose (NFOD) is highly prevalent among people who inject drugs (PWID). This can lead to an elevated risk of future overdose, causing various harms including possible death. It is essential to improve knowledge concerning this problem and its associated risk factors to inform overdose prevention and assistance programs. The primary aim of the present study was to determine the prevalence of NFOD and associated risk factors among PWID in Saveh, Iran.

Methods

In the present cross-sectional study, 272 PWID living in Saveh, Iran were interviewed face-to-face using a structured survey. Data concerning socio-demographics, substance use, risky behaviors, and services utilization data were collected. The outcome variable (i.e., NFOD) was assessed by answering “Yes” to the question: “In the past three months, have you ever overdosed (at least once) by accident?”

Results

The prevalence of NFOD among PWID in the past three months was 54%. The characteristics and behaviors that were associated with an increased risk of experiencing NFOD in the past three months were being of older age (AOR = 5.2, p < 0.05), drug use initiation under the age of 22 years (AOR = 7.8, p < 0.05), being an alcohol user (AOR = 3.0, p < 0.05), and being a simultaneous multiple drug user (AOR = 5.8, p < 0.05). Also, more recent initiates to injecting (< 2 years) had an increased risk of experiencing a non-fatal overdose in the past three months. Findings also indicated that those who (i) attended a needle and syringe program (AOR: 0.3, p < 0.05), (ii) were visited by a general practitioner (AOR: 0.03, p < 0.05), and (iii) received a psychosocial intervention (AOR: 0.1, p < 0.05) were 0.3, 0.03 and 0.1 times less likely to report non-fatal overdosing than other participants, respectively.

Conclusions

The results indicate that intervention and prevention initiatives seeking to reduce NFOD among PWID should not only be focused on the primary drug used but also the use of alcohol and polysubstance use. Specific and tailored psychological interventions combined with pharmacotherapy may be highly beneficial for PWID who experience more severe types of substance use, including alcohol use disorders and/or polysubstance abuse.

Prevalence, socio-demographics and service use determinants associated with disclosure of HIV/AIDS status to infected children: a systematic review and meta-analysis by 1985-2021

BACKGROUND

Human immunodeficiency virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) is a public health issue of global importance. To our knowledge, no previous meta-analysis documenting the prevalence, socio-demographic, and service use determinants associated with HIV/AIDS disclosure to infected children has been conducted. The present study aimed to determine the prevalence, socio-demographics and service use determinants associated with the disclosure of HIV/AIDS status to infected children.

METHODS

Studies in English published between 01 January 1985 and 01 November 2021, and available on PubMed, Scopus, Web of Science, and Cochrane electronic databases were searched. After reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria. We used fixed and random-effects meta-analysis models to estimate the pooled prevalence, pooled odds ratio (OR), and 95% confidence intervals.

RESULTS

After article duplicates were excluded, assessments of abstracts were completed, and full-text papers evaluated, 37 studies were included in this meta-analysis. The prevalence of the disclosure of HIV status to children was measured to be 41% in this research. The odds that a child of 10 years and older is informed that they are HIV-positive is 3.01 time the odds that younger children are informed. Those children who had primary or lower schooling level were 2.41 times more likely to be informed of their HIV-positive status than children with higher levels of schooling. Children who had a non-biological parents were 3.17 times more likely to have been disclose being HIV-positive; social support (OR = 8.29, 95%CI = 2.34, 29.42), children who had higher levels of social supports were 8.29 times more likely to disclose HIV-positive; the primary educational level of caregivers (OR = 2.03, 95%CI = 1.43, 2.89), respondents who had caregivers with primary education level were 2.03 times more likely to disclose HIV-positive; antiretroviral treatment (ART) adherence (OR = 2.59, 95%CI = 1.96, 3.42), participants who adhered to ART were 2.59 times more likely to disclose HIV-positive and hospital follow-up (OR = 2.82, 95%CI = 1.85, 4.29), those who had hospital follow-up were 2.82 times more likely to disclose HIV-positive; were all significantly associated with the disclosure of HIV/AIDS status to infected children.

CONCLUSION

Such data are of importance for healthcare pediatrics HIV care professionals. Facilitating HIV diagnosis and disclosure to the infected children and ensuring access to HIV treatment will likely prevent secondary HIV transmission. Healthcare professionals are expected to provide age-appropriate counseling services to this population.

Socio-demographic, clinical and service use determinants associated with HIV related stigma among people living with HIV/AIDS: a systematic review and meta-analysis

Background

Defining HIV-related stigma (HRS) can be problematic due to structural inequalities, cultural differences, discrimination by health care providers and the limitations of tools measuring stigma for people living with HIV (PLWH). This meta-analysis aimed to determine self-reported HRS and its association with socio-demographic and clinical determinants.

Methods

PubMed, Scopus, Web of Science, PsycInfo, SciELO and Cochrane electronic databases were searched and after reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes criteria. We used fixed and random-effects meta-analysis models to estimate the pooled prevalence, pooled odds ratio (OR) and 95% confidence intervals.

Results

Thirty-one studies containing 10,475 participants met the eligibility criteria. Among the potential risk factors: age > 30 years (OR = 0.93, 95%CI = 0.86, 1), living with a spouse (OR = 0.07, 95%CI = 0.02, 0.17), CD4 count < 200 (OR = 0.5, 95% CI = 0.31, 0.68), medication adherence (OR = 0.96, 95%CI = 0.94, 0.99), poor access to care (OR = 0.79, 95%CI = 0.65, 0.93), time since diagnosis, and accessibility to care (OR = 0.37, 95%CI = 0.11, 0.86) were all significantly associated with self-reported HIV stigma among PWLH.

Conclusion

Stigma is correlated with numerous negative consequences in marginalised populations including PLWH. Considering the negative association that stigma has on HIV prevention and treatment targeted evidence-based stigma reduction interventions are recommended. Interventions that are focused on a particular group, such as healthcare professionals are warranted. Rigorously designed studies with specific and validated outcome measures associated with targeted interventions may help to improve the reduction of HRS for PLWH.

Non -fatal overdose among people who inject drugs in Tehran, Iran

BACKGROUND

With increasing frequencies of non-fatal overdose in people who inject drugs (PWID), it is essential to improve our knowledge about associated risk factors for overdose to inform overdose prevention and assistance programs. The aim of present study was to determine the prevalence of non-fatal overdose and the associated risk factors among PWID in Tehran, Iran.

METHODS

Snowball sampling was used to collect data from 465 participants in Tehran using a cross-sectional survey. Consenting participants who reported drug injecting in the past month and were able to speak and comprehend Farsi enough to respond to survey questions were interviewed. The endpoint of interest was non-fatal overdose in the previous 6 months, or answering "Yes" to the question: "In the last six months, have you ever overdosed by accident? (at least once)". We used STATA v. 14 for this analysis. Statistical significance was defined as p < 0.05 for all analyses.

RESULTS

Of 465 PWIDs who participated in this study, all were male, and about half had less than a high school education. The prevalence of self-reported non-fatal overdose in the past 6 months was 38% (CI95%: 34, 43%). Our findings indicate that characteristics and behaviors that were associated with an increased risk of experiencing an overdose in the past 6 months were drug use initiation under 22 years (AOR =2.2, P < 0.05), using methamphetamine (AOR =2.8, P < 0.05), and using multiple drugs at the same time (AOR =2.1, P < 0.05). Also, more recent initiates to injecting (< 2 years) had an increased risk of experiencing an overdose in the past 6 months. The odds of experiencing a non-fatal overdose among PWIDs who regularly attended NSP were 0.6 times less than for those who did not attend regularly (OR = 0.6,95% CI: 0.2-0.9).

CONCLUSION

Methamphetamine and alcohol use were the most significant association for non-fatal overdose among PWIDs. Our results indicate that intervention and prevention initiatives seeking to reduce overdoses among PWIDs should not only be focused on the primary drug used but also the use of alcohol and poly-drug use.

Methamphetamine use and HIV risk behavior among men who inject drugs: causal inference using coarsened exact matching

BACKGROUND

Understanding the association between methamphetamine (MA) use and HIV risk behavior among people who inject drugs (PWID) will assist policy-makers and program managers to sharpen the focus of HIV prevention interventions. This study examines the relationship between MA use and HIV risk behavior among men who inject drugs (MWID) in Tehran, Iran, using coarsened exact matching (CEM).

METHODS

Data for these analyses were derived from a cross-sectional study conducted between June and July 2016. We assessed three outcomes of interest-all treated as binary variables, including distributive and receptive needle and syringe (NS) sharing and condomless sex during the month before interview. Our primary exposure of interest was whether study participants reported any MA use in the month prior to the interview. Firstly, we report the descriptive statistics for the pooled samples and matched sub-samples using CEM. The pooled and matched estimates of the associations and their 95% CI were estimated using a logistic regression model.

RESULTS

Overall, 500 MWID aged between 18 and 63 years (mean = 28.44, SD = 7.22) were recruited. Imbalances in the measured demographic characteristics and risk behaviors between MA users and non-users were attenuated using matching. In the matched samples, the regression models showed participants who reported MA use were 1.82 times more likely to report condomless sex (OR = 1.82 95% CI 1.51, 4.10; P = 0.031), and 1.35 times more likely to report distributive NS sharing in the past 30 days, as compared to MA non-users (OR = 1.35 95% CI 1.15-1.81). Finally, there was a statistically significant relationship between MA use and receptive NS sharing in the past month. People who use MA in the last month had higher odds of receptive NS sharing when compared to MA non-users (OR = 4.2 95% CI 2.7, 7.5; P = 0.013).

CONCLUSIONS

Our results show a significant relationship between MA use and HIV risk behavior among MWID in Tehran, Iran. MA use was related with increased NS sharing, which is associated with higher risk for HIV exposure and transmission.

HIV and drug related stigma and risk-taking behaviors among people who inject drugs: a systematic review and meta-analysis

The impact of HIV-related stigma on people living with HIV has been well documented, but there have been few studies examining how drug-related stigma impacts risk-taking in the lives of people who inject drugs (PWID). This meta-analysis aimed to determine HIV and drug-related stigma and the association it has with risk-taking behaviors among PWID. We searched PubMed, Science Direct, Web of Science, and Cochrane electronic databases independently in March 2019. After reviewing for any study duplicates the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria. We used fixed and random-effects meta-analysis models to estimate the pooled prevalence, pooled odds ratio (OR) and 95% confidence intervals. After a detailed assessment, a total of 14 studies containing 13,689 participants met the eligibility criteria. Among the potential risk factors: employment status, depression and sharing injecting paraphernalia had a significant relationship with HIV and drug stigma among PWIDs respectively (OR = 0.78, 95%CI = 0.62-0.98), (OR = 1.84, 95%CI = 1.45-2.33) and (OR = 2.20, 95%CI = 1.84-1.63). Illicit drug use related stigma was found to be associated with several concurrent effects. The impact of stigma should be considered in the development of drug use prevention strategies. Perceived stigma is correlated with numerous negative consequences in other populations including people living with HIV/AIDS. These data suggest this could also be generalized to people who inject drugs because it seems that individuals with internalized stigma experience drug dependence, reduced comfort in seeking help from services and higher rates of depression.
