Previous studies have shown a link between mental health functioning and involvement in HIV risk practices. The present research examines how well one specific group of men who have sex with other men (MSM) fare in terms of their mental health functioning, and then focuses on how mental health functioning relates to HIV risk practices in this population. The study was based on a national random sample of 332 MSM who use the Internet to seek men with whom they can engage in unprotected sex. Data collection was conducted via telephone interviews between January 2008 and May 2009. Depression is more common among men in this population than in the adult male population-at-large. All other measures of mental health functioning that were examined (self-esteem, impulsivity, current life satisfaction, optimism about the future) indicated low rates of mental health problem. Contrary to expectations, in nearly all instances, mental health functioning was not related to HIV risk practices.

More work needs to be done to understand the causes of depression among these men, and to assess how, if at all, depression relates to risk practices in this population. These findings suggest that factors other than mental health problems must be considered if one wishes to understand HIV risk taking in this population.

The purpose of this study is to explore the contextual determinants of HIV risk among people who inject drugs (PWID) in public settings in Nigeria.

In-depth, individual interviews were conducted with 29 street-based PWID recruited through snowball sampling in Uyo, Nigeria. Interviews were tape-recorded, transcribed, coded and analysed hematically.

Homelessness and withdrawal pains encouraged consumption of drugs in public spaces (e.g. bunks, public parks). Conversely, the benefits of participation in street drug-use scenes, including reciprocity norms that guarantee free drugs during withdrawal and protection during overdose, fostered a preference for public injecting. Although participants recognized the need to inject with sterile syringes, scarcity of syringes compelled them to improvise with old syringes or share syringes, increasing risk for HIV transmission. HIV risk was exacerbated by unlawful and discriminatory policing practices, which deterred possession of syringes and encouraged risky behaviours such as rushing injection and sharing of equipment.

Contextual factors are key determinants of HIV risk for street-based PWID. Implementation of needle and syringe programmes as well as reforming legal frameworks and policing practices to support harm reduction are needed responses.

This is one of very few qualitative studies that explore risk factors for HIV transmission among PWID in West Africa. The focus on scarcity of sterile syringes and HIV risk is unique and has important policy implications.

Informed consent, confidentiality, disclosure, policy and the wider consequences of HIV testing are issues explored in this paper concerning a man with learning disabilities who tested positive for HIV. The events and outcomes are summarised, with lessons identified for policy and practice in HIV risk management and adult protection in services for people with learning disabilities.

The purpose of this study is to explore the potential causes of HIV prevalence among young women in South Africa. Human immunodeficiency virus (HIV) is one of the leading causes of death in sub-Saharan Africa. South Africa (SA) has the largest HIV pandemic in the world with approximately 7.2 million people living with HIV as of 2017. There is a disproportionate incidence of HIV between women and men, particularly affecting young women 15–24 years of age. This paper reviewed 10 articles on the impact of HIV in SA among young women.

A total of 10 articles on HIV in SA were selected for review using academic databases including Library One Search Pro, Google Scholar, the British Medical Journal and Elsevier. The search generated 11,095 articles, which were narrowed down to 10 by the criteria of being specific to gender and age and publication period.

Five themes were identified from the findings as to the potential causes of HIV prevalence among young women these included age-disparate relationships, social factors and sexual behaviour. Impact of HIV on communities and individuals, gender and patriarchy including poverty and social isolation.

The paper shows the impact of inequalities between men and women leading to HIV infection among young women. It also shows some gaps that require further research with regards to HIV infections among young women.

Injecting drug use addiction is a main factor in hepatitis B, C infection and HIV–AIDS infection. The purpose of this paper is to measure seroprevalence of hepatitis B, C virus and HIV–AIDS amongst injecting drug users (IDUs) and its influencing factors.

The cross-sectional method was used in mid-2017 in Ahwaz city, southwest Iran. In total, 133 IDUs, aged 29–71 years (mean age=48.21 ± 10.4), were chosen from Aria addiction treatment centre. The data were collected on demographic and behavioural characteristics. In addition, serum samples were screened for those diseases.

In a total of 131 IDUs, 2 (1.5 per cent) were HIV+, 16 (11.7 per cent) HCV+ and 8 (6.1 per cent) HBV+. There was a significant correlation between diseases and IDU. Results of multiple regression stated that IDU was a more predicting variable as β=0.76 and the model was able to predict 74.1 per cent of the variance, F (3, 35)=12.42, ρ<0.001, R²=0.741, OR=3.01, 95% CI [1.44, 3.83]. The synchronised pairwise effect of age, imprisonment and IDU with GLM analysis was significant, F (2, 114)=20.433, ρ<0.000, η HCV + 2 = 0.609 , η HBV + 2 = 0.616 , and η HCV + 2 = 0.612 , λ_Wilks’=0.056. The infection rate among IDUs was significant and the most important risk factor for these infections has been intravenous drug use, together with age of misusing and imprisonment.

The non-cooperation of two samples, lack of participation of three addiction rehabilitation centres in Ahwaz city, the end of cooperation in the first two months of the implementation of the plan, and the lack of consistency of the three serum samples in the cases (two cases) were limitations of the study.

Based on the results, the following suggestions could be presented: establishing “Intervention Clubs” for treatment in the peripheral urban areas for the participation of women drug users – the responsible organisation is Cultural and Social Deputy of Ahwaz Municipality Organisation. Integration of “Small Self-caring Groups” in Sepidar Women’s Penitentiary in the East Ahwaz region – the responsible organisation is Khuzistan Province Prisons Organisation (the southwestern Iranian prisons authority); constructing “Community-based Committees” to increase the level of social intervention – the responsible organisation is the Iran Drug Control Headquarters at Iranian Presidential Office; screening of injecting drug use in the populations at risk, especially girls and women in marginalised areas – the responsible organisation is Deputy Director of Prevention and Treatment of Addiction in the Iran Welfare and Rehabilitation Organisation; establishing an “Patient Treatment Center” in high-risk areas along with directing drug users and supervising the relevant authorities – the responsible organisation is Deputy Police Commander on Social Assistance; providing education to families involved with addiction in the “Neighborhood Parks” – the responsible organisation is Deputy for Health Affairs.

They are mixed with practical implications as well.

The comprehensive harm reduction plan and prison-related issues of IDUs with shared syringe along with the pairwise age and imprisonment need to consider the above factors.

People who inject drugs (PWID) face multiple health problems, including infectious diseases and drug overdoses. Applying syndemic and risk environment frameworks, this paper aims to examine the co-occurrence and clustering of drug-related harms and their association with incarceration experience with or without in-prison drug injection.

The authors used data from a cross-sectional survey conducted in 2015 among 557 active opioid injectors. Self-reported data were collected through face-to-face or online questionnaires. They distinguished three harm categories, namely, viral infections, bacterial infections and overdoses, and built an index variable by summing the number of harm categories experienced, yielding a score from 0 to 3. Association between incarceration experience and co-occurrence of harms was modelled using a multinomial logistic regression.

Of the 557 participants, 30% reported lifetime experience of drug-related viral infection, 46% bacterial infection and 22% drug overdose. Multinomial logistic models showed that those who injected drugs during incarceration were more likely to report two (aOR = 2.35, 95% CI: 1.03–5.36) and three (aOR = 9.72, 95% CI: 3.23–29.22) harm categories than those who had never been incarcerated. They were also more likely to report three harm categories than formerly incarcerated respondents who did not inject drugs in prison (aOR = 5.14, 95% CI: 1.71–15.48).

This study provides insights of the syndemic nature of drug-related harms and highlights that drug injection during incarceration is associated with co-occurring harms. Public health interventions and policy changes are needed to limit the deleterious impact of prison on PWID.

HIV prevention among drug users continues to be a daunting challenge. Previous efforts have shown limited success. A major research question for the next generation of HIV prevention interventions for drug users is how do we design, implement, and evaluate harm reduction interventions that reach the appropriate audiences, are programmatically sustainable, maintain behavior change, and lead to meaningful changes in participants' lives. The goal of this chapter is to critique the current state of HIV prevention research and to propose using additional social science theories and methods in future approaches to behavior change. The first section of this chapter examines some of the historical and psychological factors that may have hindered progress in the field of behavioral HIV prevention. The next section presents a theoretical foundation for a social influence approach to HIV prevention interventions for drug users that considers opportunity structures within an individual's social environment. This approach emphasizes behavioral Settings, Norms, and Network Approaches to AIDS Prevention (SNNAAP). By capitalizing on naturally occurring social influence processes, promoting HIV-related behavior change among drug users may be possible. The section discusses social behavioral theories, social-oriented research methods, and individual-level factors that have been inadequately pursued in the field of HIV prevention. Examples of interventions that have incorporated social behavioral theory are presented. Next, several approaches to improving HIV prevention research methods are discussed. Finally, future directions of HIV prevention research are proposed.

Positive sexual growth is a key developmental challenge for all children and adolescents. An acquired brain injury (ABI) can create major hurdles to achieving this goal. A conceptual model will be outlined that suggests sexual growth is achieved by progress across six domains, namely: social competence versus social isolation; identity formation, individuation and independence versus dependence and lack of individual identity; physical development versus physical challenge; sexually informed and educated versus sexually ignorant and uneducated; sexually experienced versus sexually inexperienced; and sexually appropriate behaviour versus sexually inappropriate behaviour. The ability to form successful peer relationships is a key mediating factor in the developmental process. Drawing on this model, a number of strategies will be outlined that support the positive sexual development of children and adolescents after ABI.

This paper aims to examine whether greater consideration should be given to the timing of sexual health interventions within the calendar year.

The paper uses a review of the literature.

The evidence points to seasonality in a number of areas of sexual health among young people, including: the timing of first intercourse and conceptions, both of which peak in the summer and over Christmas; abortions which peak approximately two months later in February and late summer and sexually transmitted infections, which peak over the summer and autumn. In the case of conceptions there is evidence that the seasonal pattern among young people is different from that of adults. Potential explanations fall into four main categories: biological; behavioural; social, and service‐related.

Many of the studies included in this review are from the USA, and some are based on either small samples or specific risk groups, which raises questions of representativeness and generalisability. Further, it is notable how little research there has been regarding seasonal variations in other aspects of sexual behaviour, such as risk reduction practice and other potential explanatory factors such as health‐seeking behaviour and availability of services.

The findings consistently point to periods of heightened sexual activity among young people in the summer and over Christmas, and suggest that greater consideration should indeed be given to the timing of sexual health interventions within the calendar year.

To the best of the authors' knowledge, no other review of this kind has yet been found.
