High-risk behaviors and their association with awareness of HIV status among participants of a large-scale prevention intervention in Athens, Greece

Knowledge on Sexually Transmitted Infections and Dedicated Health Care Centers Among Italian Adults: Insights From a Nationwide Cross-Sectional Study

BACKGROUND

Sexually transmitted infections (STI) are a global concern. In Italy, despite the presence of publicly funded STI diagnostic centers, limited attention has been given to the knowledge of these services among the adult population. This study primarily aimed to evaluate Italian adults' knowledge about STI and dedicated health care centers. Secondarily, it explored condom usage behaviors.

METHODS

Conducted nationwide, this cross-sectional study used an online questionnaire. The primary outcomes included knowledge of dedicated STI centers and scores on the Sexually Transmitted Disease Knowledge Questionnaire (STD-KQ); secondary outcomes included inconsistent condom usage rates during various forms of intercourse.

RESULTS

With a participant count of 1036, results indicated that only 36% were aware of dedicated STI centers. The median STD-KQ score was 11 (interquartile range, 6-15). Multivariable regression models unveiled factors significantly associated with knowledge. Lesbian, gay, bisexual, transsexual, and queer (LGBTQ) individuals, health care workers, and those with higher STD-KQ scores exhibited greater STI centers' awareness. Better STD-KQ scores correlated with higher education levels, substance use, past STI diagnosis, and health care employment. Around 80% of the sample reported inconsistent condom use during different forms of intercourse. Although enhanced knowledge correlated with increased condom use, certain groups exhibited discrepancies between knowledge of STI and actual condom use.

CONCLUSIONS

These findings emphasize the need for targeted awareness campaigns to enhance accessibility to STI centers, underscoring the necessity for multifaceted interventions beyond information dissemination to address suboptimal condom usage. In providing insights into STI knowledge and behaviors among Italian adults, this research informs interventions and policy adjustments to combat STI.

Incidence of primary hepatitis C infection among people who inject drugs during 2012-2020 in Athens, Greece

One of the World Health Organization's targets for the 2030 viral hepatitis elimination strategy is to reduce new hepatitis C (HCV) infections. In Athens, Greece, people who inject drugs (PWID) have a high HCV prevalence, with increasing trends since the 2000s. This analysis aims to assess primary HCV incidence among PWID during 2012-2020. Two community-based interventions were implemented in 2012-2013 and 2018-2020 with repeated sero-behavioural surveys in each period. Participants enrolled in multiple surveys were identified through linkage. To assess trends in HCV transmission, three indicators were estimated: (i) anti-HCV prevalence among 'new' injectors (those injecting ≤2 years), (ii) indirect HCV incidence among 'new' injectors, assuming infection occurred at the midpoint between initiating injection and the first positive test, and (iii) HCV incidence from repeat participants. There were 431 and 125 'new' injectors, respectively, in 2012-2013 and 2018-2020. Αnti-HCV prevalence [95% CI] declined from 53.6% [48.8%, 58.3%] in 2012-2013 to 40.0% [31.3, 49.1%] in 2018-2020 (25.4% reduction, p = .007). The indirect estimate [95% CI] of HCV incidence among 'new' injectors decreased from 56.1 [49.3, 63.8] to 39.0/100 person-years (PYs) [29.6, 51.5] (30.5% reduction, p = .020). HCV incidence [95% CI] based on seroconversions in repeat participants (16/63 in 2012-2013 and 9/55 in 2018-2020) declined from 64.6 [39.6105.4] to 13.8/100 PYs [7.2, 26.5], respectively (78.6% reduction, p < .001). Primary HCV incidence remains high among PWID in Athens. Consistent implementation of combined interventions, including high-coverage harm reduction programs and initiatives tailored to increase access to HCV treatment, is essential to sustain the declining trends documented during 2012-2020.

Advancing the Global Fight Against HIV/Aids: Strategies, Barriers, and the Road to Eradication

HIV/AIDS remains one of the most significant global health challenges, affecting millions of people worldwide. Since the inception of the disease, various global response strategies have been devised and implemented, aiming to mitigate its impact and ultimately eradicate it. While these strategies have yielded remarkable progress, there are still key barriers impeding the global fight against the disease. This paper, thus, delves into the key global response strategies employed in response to the HIV/AIDS epidemic since its inception, examines the impediments to their successful implementation, and outlines the trajectory towards a world without AIDS. To continue the momentum in the fight against HIV/AIDS, it is imperative to adopt a multifaceted approach that addresses the existing barriers. One pivotal aspect of this approach involves intensifying efforts to improve the uptake of HIV testing. Encouraging individuals to get tested is a critical step, as it not only aids in identifying more cases of HIV infection but also facilitates the linkage of those affected to appropriate care and support services.

Hepatitis B and human immunodeficiency virus infections within correctional facilities in Ghana

Previous studies have suggested high Immunodeficiency Virus (HIV) and hepatitis B virus (HBV) prevalence in prisons in Ghana. However, this study was part of a nationally representative bio-behavioural survey and determined the prevalence of HIV and HBV among prison inmates and identified factors associated with these infections. Both biomedical and behavioural data were collected from a total of 2,443 prison inmates from 19 prison stations during 2013 in Ghana; 12 male prisons and 7 female prisons selected across the country. The national HIV screening algorithm was used for HIV testing while two rapid detection tests were used to confirm HBV infections. HIV and HBV prevalence among prisoners in Ghana were approximately 2.34% and 12.38% respectively. Only 5 inmates, had co-infection with both viruses. The prevalence of HIV was significantly lower among male inmates (1.5%) compared to the female inmates (11.8%). Age, sex, and marital status, were significantly associated with both HIV and HBV infections. However, BMI category, IDU, and time spent in prison were associated with HIV infections. The educational level was significantly associated with HBV infections. After binary logistic regression, being female (AOR: 0.18, 95% CI: 0.07-0.45, p<0.001) and having a stay of 5 years or more (AOR: 0.07, 95% CI: 0.01-0.60, p = 0.016), increased the risk of having HIV infection. While, those with no formal education (AOR: 0.65, 95% CI: 0.45-0.95, p = 0.024) and are underweight (AOR: 0.51, 95% CI: 0.27-0.99, p = 0.046), were more likely to have HBV infection. Forced penetrative sex may be a problem in the prisons. The need to have and strengthen an integrated screening, treatment and vaccination plan for the prison is emphasized. The prison does not serve as an exceptionally high risk to the general population. The findings support a critical look at the issue of forced penetrative sex in the prisons.

Comparative analysis of sexual behavior and assessment of awareness of STIs and HIV infection among young people of two generations

Background: A comparative analysis of the results of a survey of young people (belonging to two different generations: millennials and zoomers) on sexual behavior and awareness of STIs and HIV infection allows us to assess the existing characteristics of the sexual behavior of young people and contribute to the further improvement of preventive measures among young people regarding STI/HIV infection. Aims: Comparative analysis of sexual behavior and assessment of the level of knowledge about STIs and HIV infection among young people (generations Y and Z). Materials and methods: For a comparative assessment of the level of awareness on the issues of prevention and risky sexual behavior in relation to STIs and HIV infection, data from earlier sociological surveys of young people in 20012002 and in 20172020 in the city of Novosibirsk were used. Among the respondents, a questionnaire was used, consisting of 23 questions, developed by the staff of the Department of Dermatovenereology of the St. acad. I.P. Pavlov and the Center for the Sociology of Deviance and Social Control of the Institute of Sociology of the Russian Academy of Sciences, adapted by the authors. Statistical analysis was carried out using Microsoft Excel and SPSS programs. The 2 test and the independent Student's t-test were evaluated. Statistical significance was set as p0.05 Results: A total of 772 young men took part in the study, of which 321 students were interviewed in 2001-2002. (Generation Y), and 451 students in 2017-2020. (Generation Z). The results show that generations of young people (millineals and zoomers) differ from each other in terms of the source of information about STIs, sexual intercourse with strangers, condom use, and the frequency of same-sex sexual intercourse. Conclusions: There is a positive trend in the sexual behavior of the younger generation. But a more structured promotion of STI/HIV prevention is needed, which will take into account current trends and features of obtaining information from young people.

Modeling the impact of interventions during an outbreak of HIV infection among people who inject drugs in 2012-2013 in Athens, Greece

BACKGROUND

A large HIV outbreak in People Who Inject Drugs (PWID) occurred in Athens, Greece in 2011-2013. In response, opioid substitution treatment (OST) and needle and syringe programs (NSP) were scaled-up and a seek-test-treat program was introduced in mid-2012. We aim to assess the impact of these interventions.

METHODS

A mathematical model of HIV transmission among PWID was calibrated to data available over time (2009-2013) on HIV prevalence, NSP/antiretroviral treatment (ART) coverage and high-risk injection. A combined interventions scenario, including decrease in high-risk injection through linkage to OST and modification of risk behaviours and access to NSP and ART, was compared to a counterfactual scenario (no improvement at the levels of these interventions), with HIV incidence being the main outcome.

RESULTS

HIV incidence increased from <0.1 new cases/100 person-years (in 2009) to 11.0 new cases/100 person-years (in 2012). Under both models, a subsequent decline was projected following early 2012, with incidence at the end of 2013 in the combined interventions scenario being lower by 77% compared to the counterfactual. The projected reduction in incidence under the intervention scenario was in agreement with empirical data. HIV prevalence would have escalated to 20.4% (95% CrI: 16.9%, 23.6%) in 2013 under the counterfactual scenario (vs. 16.8% (95% CrI: 11.2%, 23.0%) under the combined interventions scenario). In total, 31.4% of HIV cases (392) were averted over 2012-2013.

CONCLUSION

These results underline the importance of high-coverage harm reduction programs and of community-based interventions to rapidly reach PWID most in need.

Interventions to Increase HIV Testing Uptake in Global Settings

Purpose of Review

HIV testing is the critical first step to direct people living with HIV (PLWH) to treatment. However, progress is still being made towards the UNAIDS benchmark of 95% of PLWH knowing their status by 2030. Here, we discuss recent interventions to improve HIV testing uptake in global settings.

Recent Findings

Successful facility-based HIV testing interventions involve couples and index testing, partner notification, and offering of incentives. Community-based interventions such as home-based self-testing, mobile outreach, and hybrid approaches have improved HIV testing in low-resource settings and among priority populations. Partnerships with trusted community leaders have also increased testing among populations disproportionally impacted by HIV.

Summary

Recent HIV testing interventions span a breadth of facility- and community-based approaches. Continued research is needed to engage men in sub-Saharan Africa, people who inject drugs, and people who avoid biomedical care. Interventions should consider supporting linkage to care for newly diagnosed PLWH.

Awareness, Knowledge and Risky Behaviors of Sexually Transmitted Diseases among Young People in Greece

Sexually transmitted diseases (STDs) affect mainly young individuals and cause health, social, and economic problems worldwide. The present study used a web questionnaire to assess the awareness, knowledge, sexual behaviors, and common practices regarding STDs in young Greek adults. The 1833 individuals, aged 18–30 years, who responded to the study seem to be particularly knowledgeable regarding STDs such as AIDS (97.7%), warts (97%), Chlamydia (92.2%), genital herpes (89.9%), syphilis (81.9%), and gonorrhea (72.1%), whereas lower percentages were noted for trichomoniasis (39.3%), Molluscum contagiosum (12.9%), mycoplasmosis (11.6%), and amoebiasis (7.4%). Regarding oral STD transmission, participants replied correctly for genital herpes (45%), warts (35.8%), and AIDS (HIV; 33.8%), whereas 30.2% were unfamiliar with oral sexual transmission. Of the participants, 52% were not aware that STDs might cause infertility. Only 40.4% of the respondents reported always using condoms during sexual intercourse, and 48.6% had never been tested for STDs. The majority of the young population (55%) presented a moderate knowledge STD score (41–60%) and was associated with demographic parameters such as age, gender, sexual preference, number of sexual partners, and residence (p < 0.05). These findings provide important information regarding the prevention of STDs and highlight the significance of developing more effective sex education programs for young people in Greece.

Contextual factors associated with knowledge and attitudes of HIV/AIDS among Malawian women of reproductive age

BACKGROUND

Increasing the knowledge and attitude toward human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a key in the management of the condition. However, in Malawi, there is limited information regarding individual- and community-level factors associated with HIV/AIDS knowledge and attitudes. This study examined the contextual factors associated with HIV/AIDS knowledge and attitudes among women of childbearing age (WOCBA) (aged 15-49 years) in Malawi.

METHODS

The 2015-16 Malawi demographic and health survey was used to analyze 24 562 WOCBA who were nested in 850 communities. Mixed effects logistic regression models were fitted to estimate the fixed and random effects of individual- and community-level factors on HIV/AIDS knowledge and attitudes.

RESULTS

Approximately 30.9% of the participants had good HIV/AIDS knowledge while 80.5% had good HIV/AIDS attitudes. Among others, at the individual-level, woman's age, educational level and household wealth were positively associated with both good HIV/AIDS knowledge and attitudes. At the community-level, those from communities with a high percentage of women complaining about the distance to health facility were less likely to have both good HIV/AIDS knowledge and attitudes.

CONCLUSIONS

Individual- and community-level factors have been shown to be associated with HIV/AIDS knowledge and attitudes among WOCBA in Malawi. Additionally, residual heterogeneity in terms of HIV/AIDS knowledge and attitudes across communities was observed. Therefore, thorough profiling of communities when designing public health programs and strategies may prove beneficial.
