Risk behaviors for HIV infection. A review of emerging trends

Amplified HIV Transmission Risk Among People Living With HIV in Southeast Brazil

ABSTRACT

This study investigated the factors associated with amplified HIV transmission risk among people living with HIV from a city in southeast Brazil. A cross-sectional study was conducted with 397 people living with HIV recruited in infectious diseases clinics. Data on risk of HIV transmission, sociodemographic characteristics, sexual behaviors, professional counseling, serological HIV status, HIV-related clinical data, and beliefs about risk of HIV transmission were collected through interviews and medical records. Hierarchical ordered multinomial regression analyses were performed. Amplified HIV risk transmission was associated with lower age, alcohol consumption before having sex, illicit drug use before sexual intercourse, and not receiving professional counseling about HIV transmission. The belief that HIV can be transmitted to a partner not living with HIV was associated with lower likelihood of amplified risk for HIV transmission. Our findings suggest the importance of minimizing substance use before having sex, professional counseling, and beliefs about HIV transmission on amplified HIV risk transmission.

Risky Sexual Behaviour among HIV-Infected Adults in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

Background

Risky sexual behaviour raises serious public health concerns. The pooled prevalence of risky sexual behaviours among adults living with HIV/AIDS in sub-Saharan Africa was unknown. This systematic review determined the pooled prevalence of risky sexual behaviours and associated factors among HIV-infected adults in sub-Saharan Africa.

Methods

International databases such as PubMed, CINAHL, Google Scholar, and African Journals OnLine were systematically searched to identify articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline was used to conduct the review. All necessary data were extracted independently. Heterogeneity and publication bias were assessed by I-squared statistics and Egger's test, respectively. The random-effects meta-analysis model was used to estimate the pooled prevalence. The association between predictors and dependent variable was determined by a pooled odds ratio (OR) with a 95% confidence interval (CI).

Result

In this study, 3713 articles were retrieved from various databases, and 22 of them were included. The pooled prevalence of risky sexual behaviour in sub-Saharan Africa was 36.16% (95% CI: 28.36-44.34) with significant heterogeneity among studies (I2 = 98.86%, p < 0.001). Risky sexual behaviour was significantly associated with the nondisclosure of HIV status (AOR = 1.97, 95% CI: 1.18, 2.76) and alcohol consumption (AOR = 2.29, 95% CI: 1.21, 3.36).

Conclusion

A significant percentage of participants engaged in risky sexual behaviour. Risky sexual behaviour was associated with failure to disclose HIV status and alcohol consumption. Healthcare professionals should advise HIV-positive patients on risk reduction measures like disclosing their HIV status to their sexual partners and avoiding alcohol use in order to promote consistent condom use.

Cognitive Behavioral Therapy for AIDS Prevention among College Students in China: A Cluster Randomized Controlled Trial

BACKGROUND

Acquired immune deficiency syndrome (AIDS) is a serious worldwide public health problem and has become the focus of prevention and control in China, while the student population is the key population for AIDS prevention.

OBJECTIVE

The purpose of this study was to investigate the effects of cognitive behavioral therapy (CBT) on college students' AIDS-related cognitions, attitudes, and behaviors, and to find programmatic strategies for AIDS prevention in terms of changing college students' cognitions and behaviors.

METHODS

In a cluster randomized controlled trial, 233 undergraduate students were assigned to the CBT group (CBT-based intervention, n=92), the TAU group (treatment as usual, n=72), and the CON group (no intervention, n=59). AIDS-related knowledge, attitudes, and behaviors of participants were assessed at pre-intervention, post-intervention, and follow-up.

RESULTS

After one month of the study, AIDS-related knowledge, attitudes, and behaviors improved in both the TAU and CBT groups, while there were no significant changes in the CON group. The intervention effect was more significant and sustainable in the CBT group compared to the TAU group.

CONCLUSIONS

The application of CBT in AIDS prevention among college students is feasible, acceptable, and effective. CBT can increase the level of knowledge about AIDS, improve AIDS-related attitudes, and increase willingness to use condoms. CBT is expected to replace traditional health education as an innovative tool for AIDS prevention because of its long-lasting and efficacious nature.

Internalized homophobia and sexual risk behavior in men who have sex with men: The mediational role of sexual self-concept

Men who have sex with men (MSM) are one of the populations most likely to be infected with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) worldwide. Sexual risk behaviors (SRB) are the main route of HIV transmission. Among the factors associated with SRB, internalized homophobia (rejection of one’s sexuality) is a risk factor unique for MSM. However, how this factor influences SRB is not clear. Therefore, the present study attempts to clarify the mechanism of action of the relationship between internalized homophobia on SRB based on the mediating effects of sexual self-concept. A study was conducted with 124 MSM living in Chile over 18 years of age (M = 24.4 and SD = 4.19). Through path analysis, it was observed that internalized homophobia has slight inverse effects on SRBs (multiple sexual partners and sexual activity under the influence of alcohol or drugs) when the sexual self-efficacy dimension acts as a mediating variable. These findings suggest that developing sexually transmitted infections (STIs) and HIV/AIDS prevention campaigns focused on MSM must highlight the development of a healthy sexual self-concept and address self-stigma.

Hepatitis B and C in Immigrants and Refugees in Central Brazil: Prevalence, Associated Factors, and Immunization

Introduction: Eliminating hepatitis B and C in immigrant and refugee populations is a significant challenge worldwide. Given the lack of information in Brazil, this study aimed to estimate the prevalence of infections caused by hepatitis B and C viruses and factors associated with hepatitis B in immigrants and refugees residing in central Brazil. Methods: An observational, cross-sectional, and analytical study was conducted from July 2019 to January 2020 with 365 immigrants and refugees. Hepatitis B was detected by a rapid immunochromatographic test, enzyme immunoassay, and chemiluminescence, and hepatitis C by rapid immunochromatographic test. Multiple analysis was used to assess factors associated with hepatitis B infection. Results: Of the participants, 57.8% were from Haiti and 35.6% were from Venezuela. Most had been in Brazil for less than 2 years (71.2%). The prevalence of HBV infection and exposure was 6.6% (95% CI: 4.5–9.6%) and 27.9% (95% CI: 23.6–2.8%), respectively, and 34% had isolated anti-HBs positivity. Reporting a sexually transmitted infection was statistically associated with HBV infection (OR: 7.8; 95% CI: 2.3–26.4). No participant with positive anti-HCV serology was found. Conclusions: The study showed that participants were outside the reach of prevention and control actions for hepatitis B. Therefore, public health strategies must be designed to reach, inform, and vaccinate this group.

HIV/AIDS-Related Knowledge and Attitudes Among Chinese College Students and Associated Factors: A Cross-Sectional Study

In recent years, adolescent has become one of the high-risk groups for HIV. Meanwhile, good HIV awareness and positive attitude are essential for HIV prevention. This study aims to evaluate the extent to which college students understand HIV and their attitudes toward HIV-infected patients, as well as the correlative factors. The data used in this study came from a cross-sectional survey. An anonymous online questionnaire was used to investigate the demographic characteristics, HIV/AIDS-related knowledge, and attitudes toward HIV-infected patients of 17,678 students from a university in Henan. Descriptive statistics, Chi-square test and logistic regression were used to analyze differences and connections between variables in SPSS version 25.0. Participants' HIV/AIDS-related knowledge awareness rate was 80.8%. Levels of students' HIV/AIDS-related knowledge correlated with their gender, nationality, marital status, and their grade (p < 0.01). Female students [OR = 0.757, 95% CI (0.699-0.820)] and minority students (OR = 0.717, 95% CI (0.619-0.832)] had insufficient HIV health education knowledge. Meanwhile, male students (OR = 0.845, 95% CI (0.773-0.924)], and students with good HIV knowledge (OR unaware-ness/awareness = 2.385, 95% CI (2.111-2.694)] were more likely to hold a positive attitude toward HIV-infected patients. The relevant education departments should strengthen and promote the education of AIDS transmission and prevention. Many college students still hold negative attitude toward HIV-infected patients. The government should further make efforts to eliminate social discrimination in HIV-infected patients and lead people to approach HIV-infected patients fairly.
