Health Promotion Interventions

Background Rates of sexually transmissible infections (STIs) have increased over recent years among gay men and other men who have sex with men (MSM) in England and Wales. HIV diagnoses remain high in this group and men with diagnosed HIV are disproportionally affected by STIs. MSM are therefore a priority for health promotion efforts to reduce STIs. Understanding awareness of and attitudes towards STIs is essential in developing health promotion interventions to reduce prevalence. Methods: Eight focus group discussions (FGDs) with a total of 61 MSM in four English cities included a ranking exercise to gauge how ‘scary’ participants thought 11 STIs are. The exercise sought insights into participants’ awareness of, knowledge about and attitudes towards STIs and blood-borne viruses (BBVs). FGDs were audio-recorded, transcribed and data analysed thematically. Results: All groups ranked HIV and Hepatitis C virus (HCV) as the scariest infections, and the majority ranked syphilis and herpes as highly scary. Scabies was ranked as the least scary by most groups. Rankings were dependent on how well informed participants felt about an infection, its transmission mechanisms, health affect and the availability of vaccines and treatment. Personal experience or that of friends influenced perceptions of particular infections, as did their prevalence, treatment options, visibility of symptoms and whether an STI could be cleared from the body. Conclusions: The study findings suggest that, although some MSM are well informed, there is widespread lack of knowledge about the prevalence, modes of transmission, health implications and treatment regimens of particular STIs.

Background Hepatitis A is a fecal-oral infection caused by hepatitis A virus (HAV). Men who have sex with men (MSM) and transgender women (TW) have been reported as target groups for HAV infection. This study aimed to determine the seroprevalence, risk factors, and circulating strains associated with HAV infection among MSM and TW in Central Brazil. Methods A cross-sectional study was conducted from November 2011 to September 2013. Serum samples were collected from 425 individuals for anti-HAV antibody testing and HAV molecular characterization. Of them, 149 (35.1%) participants were self-identified as transgender women. Statistical analysis was performed to evaluate the risk factors of HAV seropositivity. Results The seroprevalence of HAV exposure was 69.7% (95% Confidence Interval: 65.3–74.0%). Serological evidence of HAV was significantly higher in participants who self-identified as transgender women (83.2%) than MSM (62.3%). Increasing age, non-white race, and lower monthly household income were independently associated with HAV exposure among MSM. Only lower monthly household income was independently associated with HAV exposure among TW. One anti-HAV IgM positive sample, from a transgender woman (0.2%), was detected and classified as subgenotype IA. Conclusions High HAV prevalence was observed, markedly among TW. Considering the risky sexual behaviors this population is exposed to, HAV vaccination and prevention programs targeting this population should be considered to prevent outbreaks and the burden of the disease.

Abstract This research reports on newspaper representations of PrEP, a HIV-prevention drug recently made available on a trial basis to at-risk individuals in England. Using corpus-assisted queer critical discourse analysis, we investigate the linguistic representations of the users of PrEP within three leading British newspapers from across the political spectrum between 2014–18. We find that users of PrEP are most frequently positioned as ‘men who have sex with men’ or ‘gay men’, a representation that we argue limits public awareness of HIV itself, and of available HIV prevention. Furthermore, while the most left-leaning newspaper in our corpus focuses on the human benefit of PrEP, the most right-leaning newspaper takes a moralistic stance which frames gay men as risk-taking and therefore less deserving of healthcare funding than other groups. We therefore argue that certain representations of PrEP’s beneficiaries are implicitly homophobic, and that most representations are unhelpfully restrictive.

Abstract Background A hepatitis A epidemic occurred among men who have sex with men (MSM) in Japan in 2017–2018. In this study, we employ a parsimonious mathematical model to epidemiologically investigate the dynamics of infection, aiming to evaluate the effectiveness of campaign-based interventions among MSM to raise awareness of the situation. Methods A mathematical model describing a mixture of human-to-human transmission and environmental transmission was fitted to surveillance data. Taking seasonally varying environmental transmission into account, we estimated the reproduction number of hepatitis A virus during the course of epidemic, and, especially, the abrupt decline in this reproduction number following campaign-based interventions. Results The reproduction number prior to the countermeasures ranged from 2.6 to 3.1 and then began to decrease following campaign-based interventions. After the first countermeasure, the reproduction number decreased, but the epidemic remained supercritical (i.e., Rt > 1). The value of Rt dropped well below one following the second countermeasure, which used web articles to widely disseminate information about the epidemic risk. Conclusions Although the effective reproduction number, Rt, changes because of both intrinsic and extrinsic factors, the timing of the examined countermeasures against hepatitis A in the MSM population was consistent with the abrupt declines observed in Rt. Even without vaccination, the epidemic was brought under control, and risky behaviors may have been changed by the increase in situation awareness reached through web articles.

Between 1 September 2008 and 9 March 2009, 150 cases of hepatitis A were reported in Barcelona, representing a threefold increase compared with the same period in the previous two years. The majority of the cases occurred in adult men, including 87 who reported having sex with men. This indicated the possibility of an outbreak ongoing in the population of men who have sex with men (MSM) and emphasised the need to target this community with more effective vaccination programmes.

An increased number of hepatitis A cases among refugees, asylum seekers and migrants residing in hosting facilities in Greece were recorded between April and December 2016. In total, 177 laboratory-confirmed symptomatic cases were reported; of these, 149 (84%) occurred in hosting camps mostly among Syrian children under 15 years. All cases reported symptom onset after their entry into the country. Public health interventions focused on hygiene measures and vaccination.
