A systematic review by Laith Abu-Raddad and colleagues collates and analyzes the epidemiology of HIV among men who have sex with men in Middle Eastern and North African countries

HIV-1 molecular epidemiology evidence and transmission patterns in the Middle East and North Africa.

The distribution of HIV-1 subtypes in a population tracks the spread and evolution of the epidemic. This study is a systematic review of all available evidence on HIV-1 molecular epidemiology and subtype distribution in the Middle East and North Africa. Sources of data included Medline and various institutional documents and databases. In several countries, a diverse distribution of HIV-1 subtypes was observed principally reflecting travel-related exogenous exposures. A trend for a dominant HIV-1 subtype was observed in a few other settings and was often linked to HIV transmission within specific high-risk groups such as subtype A and CRF35_AD among injecting drug users and subtype C among commercial sex networks. Multiple exogenous introductions of HIV-1 variants seemed common to all countries, as observed from the high diversity in subtypes, or the high genetic divergence among any specific subtype even if predominant. In several countries though, epidemic-type clustering of specific subtypes suggests established or nascent HIV epidemics among classic core risk groups for HIV infection. HIV prevention efforts in MENA must be prioritized for these high-risk groups

Epidemiology of HIV infection in the Middle East and North Africa.

OBJECTIVE: The Middle East and North Africa (MENA) region continues to be perceived as a region with very limited HIV epidemiological data, raising many controversies about the status of the epidemic in this part of the world. The objective of this review and synthesis was to address the dearth of strategic interpretable data on HIV in MENA by delineating a data-driven overview of HIV epidemiology in this region. METHODS: A comprehensive systematic review of HIV, sexually transmitted infections (STIs) and risk behavior studies in MENA, irrespective of design, was undertaken. Sources of data included Medline for peer-reviewed publications, Google Scholar for other scientific literature published in nonindexed local and regional journals, international organizations reports and databases, country-level reports and database including governmental and nongovernmental organizations publications, as well as various other institutional documents. RESULTS: Over 5000 sources of data related to HIV and STIs were identified and reviewed. The quality of data and nature of study designs varied substantially. There was no evidence for a sustainable HIV epidemic in the general population in any of the MENA countries, except possibly for southern Sudan. The general pattern in different countries in MENA points towards emerging epidemics in high-risk populations including injecting drug users, men who have sex with men (MSM) and to a lesser extent female sex workers, with heterogeneity between countries on the relative role of each of these high-risk groups. Exogenous HIV exposures among nationals linked to travel abroad appeared to be the dominant HIV transmission pattern in a few MENA countries with no evidence for much epidemic or endemic transmission. The role of bridging populations in bridging the HIV infection to the general population was found to be very limited. CONCLUSION: Although they do not provide complete protection against HIV spread, near universal male circumcision and possibly the prevailing sexually conservative cultural norms seemed to have played so far a protective role in slowing and limiting HIV transmission in MENA relative to other regions. If the existing social and epidemiological context remains largely the same, HIV epidemic transmission is likely to remain confined to high-risk populations and their sexual partners, in addition to exogenous exposures. HIV prevention efforts in this region, which continue to be stymied by stigma associated with HIV/AIDS and related risk behaviors, need to be aggressively expanded with a focus on controlling HIV spread along the contours of risk and vulnerability. There is still a window of opportunity to control further HIV transmission among high-risk groups in MENA that, if missed, may entail a health and socioeconomic burden that the region, in large part, is unprepared for

Characterising HIV/AIDS knowledge and attitudes in the Middle East and North Africa: Systematic review and data synthesis

This article reviews HIV/AIDS knowledge and attitudes in various population groups in the Middle East and North Africa (MENA), and highlights their relevance to HIV epidemiology and the design and implementation of preventions and treatment efforts. PubMed and the MENA HIV/AIDS Epidemiology Synthesis Project database of grey/unpublished literature were searched. Levels of knowledge were categorised based on presence of basic knowledge, comprehensive knowledge, and misconceptions and misinformation. Attitudes towards people living with HIV/AIDS (PLHIV) were classified into positive or negative. Basic knowledge was overall high among key populations at higher risk of infection (KPAR), and bridging and general population groups, but still a few population pockets had low basic knowledge. Level of comprehensive knowledge was overall low, and misinformation and misconceptions were prevalent. Some KPAR, including people who inject drugs, men who have sex with men, and female sex workers, were unaware of some modes of HIV transmission. Perception of risk of infection was low even among KPAR. We found differentials in knowledge putting women, rural populations, refugees, and other marginalised minorities at a disadvantage. Attitudes towards PLHIV tended to be negative. These findings are of concern, particularly for KPAR currently experiencing emerging HIV epidemics

The distribution of new HIV infections by mode of exposure in Morocco.

OBJECTIVES: Building on a wealth of new empirical data, the objective of this study was to estimate the distribution of new HIV infections in Morocco by mode of exposure using the modes of transmission (MoT) mathematical model. METHODS: The MoT model was implemented within a collaboration with the Morocco Ministry of Health and the Joint United Nations Programme on HIV/AIDS. The model was parameterised through a comprehensive review and synthesis of HIV and risk behaviour data in Morocco, mainly through the Middle East and North Africa HIV/AIDS Synthesis Project. Uncertainty analyses were used to assess the reliability of and uncertainty around our calculated estimates. RESULTS: Female sex workers (FSWs), clients of FSWs, men who have sex with men (MSM) and injecting drug users (IDUs) contributed 14%, 24%, 14% and 7% of new HIV infections, respectively. Two-thirds (67%) of new HIV infections occurred among FSWs, clients of FSWs, MSM and IDUs, or among the stable sexual partners of these populations. Casual heterosexual sex contributed 7% of HIV infections. More than half (52%) of HIV incidence is among females, but 71% of these infections are due to an infected spouse. The vast majority of HIV infections among men (89%) are due to high-risk behaviour. A very small HIV incidence is predicted to arise from medical injections or blood transfusions (0.1%). CONCLUSIONS: The HIV epidemic in Morocco is driven by HIV incidence in high-risk population groups, with commercial heterosexual sex being the largest contributor to incidence. There is a need to focus HIV response more on these populations, mainly through proactive and sustainable HIV surveillance, and the expansion and increased geographical coverage of services such as condom promotion among FSWs, voluntary counselling and testing, harm reduction and treatment

Co-occurrence of tobacco product use, substance use, and mental health problems among youth: Findings from wave 1 (2013–2014) of the population assessment of tobacco and health (PATH) study

Introduction: Cigarette use is associated with substance use and mental health problems among youth, but as- sociations are unknown for non-cigarette tobacco product use, as well as the increasingly common poly-tobacco use. Methods: The current study examined co-occurrence of substance use and mental health problems across tobacco products among 13,617 youth aged 12–17 years from Wave 1 (2013–2014) of the nationally representative Population Assessment of Tobacco and Health (PATH) Study. Participants self-reported ever cigarette, e-cigar- ette, smokeless tobacco, traditional cigar, cigarillo, filtered cigar, hookah, and other tobacco product use; al- cohol, marijuana, and other drugs; and lifetime substance use, internalizing and externalizing problems. Results: In multivariable regression analyses, use of each tobacco product was associated with substance use, particularly cigarillos and marijuana (AOR=18.9, 95% CI: 15.3–23.4). Cigarette (AOR=14.7, 95% CI: 11.8–18.2) and cigarillo (AOR = 8.1, 95% CI: 6.3–10.3) use were strongly associated with substance use pro- blems and tobacco users were more likely to report internalizing (AOR = 1.6, 95% CI: 1.4–1.8) and ex- ternalizing (AOR = 1.4, 95% CI: 1.3–1.6) problems. Female tobacco users were more likely to have internalizing problems than male tobacco users. Poly-tobacco users were more likely than exclusive users to use substances (AOR = 3.4, 95% CI: 2.7–4.3) and have mental health (AOR = 1.2, 95% CI: 1.0–1.5) and substance use (AOR = 4.7, 95% CI: 3.4–6.6) problems. Conclusions: Regardless of the tobacco product used, findings reveal high co-occurrence of substance use and mental health problems among youth tobacco users, especially poly-tobacco users. These findings suggest the need to address comorbidities among high risk youth in prevention and treatment settings

Mental Health Problems and Onset of Tobacco Use Among 12- to 24-Year-Olds in the PATH Study

Objective: To examine whether mental health problems predict incident use of 12 different tobacco products in a nationally representative sample of youth and young adults. Method: This study analyzed Wave (W) 1 and W2 data from 10,533 12- to 24-year-old W1 never tobacco users in the Population Assessment of Tobacco and Health (PATH) Study. Self-reported lifetime internalizing and externalizing symptoms were assessed at W1. Past 12-month use of cigarettes, electronic nicotine delivery systems (ENDS), traditional cigars, cigarillos, filtered cigars, pipe, hookah, snus pouches, other smokeless tobacco, bidis and kreteks (youth only), and dissolvable tobacco was assessed at W2. Results:In multivariable regression analyses, high-severity W1 interalizing (adjusted odds ratio [AOR] = 1.5, 95% CI = 1.3 - 1.8) and externalizing (AOR=1.3, 95% CI=1.1-1.5) problems predicted W2 onset of any tobacco use compared to no/low/moderate severity. High-severity W1 internalizing problems predicted W2 use onset across most tobacco products. High-severity W1 externalizing problems predicted onset of any tabacco (AOR=1.6, 95% C1=1.3-1.8), cigarettes (AOR=1.4, 95% CI=1.0-2.0), ENDS (AOR=1.8, 95& CI=1.5-2.1), and cigarillos (AOR=1.5, 95% CI=1.0-2.1) among youth only. Conclusion: Internalizing and externalizing problems predicted onset of any tobacco use. However, findings differed for internalizing and exter- nalizing problems across tobacco products, and by age, gender, and race/ethnicity. In addition to screening for tobacco product use, health care providers should screen for a range of mental health problems as a predictor of tobacco use. Interventions addressing mental health problems may prevent youth from initiating tobacco use
