Determinants of Heterosexual Adolescents Having Sex with Female Sex Workers in Singapore

Exposure to Pornography and Adolescent Sexual Behavior: Systematic Review

BACKGROUND

Formative experiences in adolescence lay the foundation for healthy and pleasurable romantic and sexual relationships. Exposure to pornography may affect these experiences.

OBJECTIVE

We aimed to synthesize evidence published in the past decade on the relationship between exposure to pornography and sexual behavior (earlier age of first sex [<16 years], condomless sex, past-year multiple partners [>1], lifetime multiple partners [>1], group sex, sexual aggression including forced sex, paid sex, teenage pregnancy, and history of sexually transmitted infection) in adolescents aged between 10 and 19 years.

METHODS

We identified 19 eligible studies by searching MEDLINE, PsycINFO, Cochrane, CINAHL, Embase, and Web of Science databases from January 2010 to November 2022.

RESULTS

Out of 8 studies that assessed earlier age of first sex, 5 studies, including 1 longitudinal study, found a statistically significant association with exposure to pornography. Given that most studies were cross-sectional or had substantial limitations, causal inference could not be made. Also, exposure to pornography was not measured consistently. The evidence was conflicting or insufficient to draw any conclusions regarding other outcomes.

CONCLUSIONS

More quantitative research is needed to elucidate the association between pornography exposure and sexual behavior, and sex education should adopt evidence-based approaches to minimize the potential harms from pornography.

The Potential Cutaneous Effects of Pornography Addiction: A Narrative Review

Pornography addiction is an area of increasing concern, particularly due to the ubiquitous nature of pornographic material on the Internet. Even so, there is no formal Diagnostic and Statistical Manual of Mental Disorders (DSM-5) inclusion of compulsive pornography use as a behavioral addiction. Although the psychosocial impacts of pornography addiction have been studied, the risk of direct skin injuries and behavioral changes brought about by excessive pornography usage remain to be seen. Adult males constitute the majority of cases of engaging in risky and violent sexual behaviors with an unclear association with pornography consumption. Adult females may be likely to copy pubic hair trimming patterns analogous to those seen in pornographic content, even though attitudes towards labiaplasty are unclear. Finally, adolescents regularly exposed to pornography have been found to replicate sexual activity seen in pornographic material and have earlier sexual activity. In the literature evaluated, an association between pornographic material and direct cutaneous disease remains a major area of further research.

Systematic Review of Interventions to Reduce HIV Risk Among Men Who Purchase Sex in Low- and Middle-Income Countries: Outcomes, Lessons Learned, and Opportunities for Future Interventions

Along with other partners of key population groups, men who purchase sex (MWPS) contributed to around 18% of new reported HIV cases in 2018 among people aged 15-49 years worldwide. A systematic review was performed to evaluate interventions conducted to reduce HIV risk among MWPS in low- and middle-income countries (LMICs). A comprehensive search of studies published in Embase, Medline, Global Health, Scopus, and Cinahl was performed. Among 32,115 studies found, 21 studies met the review's inclusion criteria. Only four studies recruited MWPS, while the rest recruited groups often used as proxy populations for MWPS. The interventions were made primarily to increase HIV-related knowledge or perceptions through education and to improve condom usage rates through promotion and distribution. Few studies evaluated the impact of interventions on HIV testing rates and none looked at HIV treatment. Given the important role of testing as a prevention gate, together with UNAIDS' 90-90-90 testing and treatment coverage goals for people infected with HIV, more studies which evaluate the impact of HIV testing and treatment provision among this group are needed.

HIV Prevalence and Factors Influencing the Uptake of Voluntary HIV Counseling and Testing among Older Clients of Female Sex Workers in Liuzhou and Fuyang Cities, China, 2016-2017: A Cross-Sectional Study

Objective

To compare the prevalence of HIV and associated factors for participating HIV voluntary counseling and testing (VCT) among older clients of female sex workers (CFSWs) in Liuzhou City and Fuyang City in China.

Methods

A cross-sectional study was conducted and the study employed 978 male CFSWs, aged 50 years and above from October 2016 to December 2017. All participants were required to complete a questionnaire and provide blood samples for HIV testing. Multivariate logistic regression analysis was used to analyze the influential factors of using VCT program and tested for HIV.

Results

The HIV infection prevalence rate was 1.2% and 0.5%, while 52.3% and 54.6% participants had ever utilized VCT service and tested for HIV in Liuzhou City and Fuyang City, respectively. The older CFSWs who ever heard of VCT program were more likely to uptake VCT program in both cities (OR_Liuzhou = 2.224, OR_Fuyang = 2.421). Participants, whose marital status was married or cohabiting (OR_Liuzhou = 0.548, OR_Fuyang = 0.495), who have stigma against individuals who are living with HIV/AIDS (OR_Liuzhou = 0.273, OR_Fuyang = 0.371), whose monthly income is more than 500 yuan (OR_Liuzhou = 0.622, OR_Fuyang = 0.600), and whose age is more than 60 years old (OR_Liuzhou = 0.639, OR_Fuyang = 0.554), were less likely to visit VCT clinics. Those who are worried about HIV-infected participants were more likely to utilize VCT services in Fuyang City (AOR = 1.838, 95%CI : 1.146‐2.948).

Conclusion

Combine strategy will be needed to promote the utilization of VCT service, based on the socioeconomic characteristics of older male CFSWs in different cities of China.

Sexual behavior pattern in the young attending sexually transmitted infection clinic in a tertiary health-care center

INTRODUCTION

Half of all new HIV infections occur in young people(15-24years). Unfortunately, the study on the sexual behaviour pattern in these age group is lacking.

MATERIALS AND METHODS

It is retrospective, cross sectional study assessing adolescent and youth between 10 to 24 years presenting to STD clinic in a tertiary health care centre as a part of their risk assessment.

RESULTS

Adolescent and youth were a total of 17.13%(165) amongst 963 STD clinic attendees. The male to female ratio was 84:81. The mean age for male±1SD was 21.17±2.26 years and for female±1SD was 20.54±2.37 years. Around 47.27% (78) were students at various levels of education. Earliest onset of sexual activity was at 14 years. Risky sexual behaviour was reported in 75.75% clients. Onset of sexual activity was earlier in females with 24.6% having sex before the age of 18 years as compared to 15.4% in males. Condom use was poor. Around 63% had heard of HIV or AIDS.

CONCLUSION

The young being a vulnerable age group, education on safe sex, condom use and other protective measures should be strengthened.

Risky sexual behaviors among Malay adolescents: a comparison with Chinese adolescents in Singapore

OBJECTIVE

Malays, with majority of the individuals being Muslim, form the largest ethnic group in Southeast Asia. This region is experiencing a rising incidence of HIV infections. Due to circumcision and prohibition of sex outside marriage, being Muslim was argued to be a protective factor against sexually transmitted infections (STI) and Human Immunodeficiency Virus (HIV). However, Malay adolescents were found to be more likely to contract chlamydia and gonorrhea than non-Malay adolescents in Singapore.

DESIGN

Using a cross-sectional survey, we examined and compared safer sex knowledge, attitudes and self-efficacy, and sexual behaviors of 248 sexually active Malay adolescents with 384 Chinese adolescents aged 16-19 years in Singapore. Poisson regression, adjusted for socio-demographic characteristics, was used for modeling each dependent variable. Adjusted prevalence ratios (aPR) with 95% confidence intervals (CI) were obtained.

RESULTS

On multivariate analysis, Malay adolescents were more likely to report marginally unfavorable attitude towards condom use (aPR 1.21 CI 1.00-1.48) and significantly lower confidence in using condoms correctly (aPR 1.24 CI 1.05-1.47) than Chinese adolescents. They were also more likely to report significantly younger first sex age (aPR 0.98 CI 0.96-1.00), never use of condoms for vaginal sex (aPR 1.32 CI 1.16-1.49) and anal sex (aPR 1.75 CI 1.11-2.76) and non-use of contraceptives at last sex (aPR 1.30 CI 1.17-1.45) than Chinese respondents. Malay males were less likely to buy sex (aPR 0.56 CI 0.37-0.85), but they reported higher likelihood of inconsistent condom use with female sex workers (aPR 2.24 CI 1.30-3.87).

CONCLUSION

Malay ethnicity was associated with unfavorable condom use attitude and lower self-efficacy in using condoms, which was consistent with risky sexual behaviors such as non-use of condoms. Future research should use mixed methods to explore and identify cultural influences to these behaviors.
