Sexual Risk Behavior among South African Adolescents: Is Orphan Status a Factor?

There is concern that orphans may be at particular risk of HIV infection due to earlier age of sexual onset and higher likelihood of sexual exploitation or abuse; however, there is limited empirical evidence examining this phenomenon. Utilizing data from 1694 Black South African youth aged 14–18, of whom 31% are classified as orphaned, this analysis explores the relationship between orphan status and sexual risk. The analysis found both male and female orphans significantly more likely to have engaged in sex as compared to non-orphans (49% vs. 39%). After adjusting for socio-demographic variables, orphans were nearly one and half times more likely than non-orphans to have had sex. Among sexually active youth, orphans reported younger age of sexual intercourse with 23% of orphans having had sex by age 13 or younger compared to 15% of non-orphans. Programmatic implications of these findings for the care and protection of orphans are discussed.

Sexual Risk Taking, STI and HIV Prevalence Among Men Who Have Sex with Men in Six Indonesian Cities

Using surveillance data on men who have sex with men (MSM) from six Indonesian cities, this article reports prevalence of sexual risk taking, HIV and other sexually transmitted infections. Factors associated with HIV, other STIs and consistent condom use were assessed. Behavioral data were collected from 1,450 MSM, among whom 749 were tested for HIV and syphilis and 738 for gonorrhea and Chlamydia. Associations were assessed using multivariate logistic regression. Over 80% of MSM knew HIV transmission routes, 65% of MSM had multiple male sexual partners, 27% unprotected anal sex with multiple male partners, and 27% sex with a female in the prior month. Consistent condom use ranged from 30 to 40% with male partners and 20 to 30% with female partners, depending upon partner type. HIV prevalence averaged 5.2%, but was 8.0% in Jakarta. Prevalence of rectal gonorrhea or Chlamydia was 32%. Multivariate analyses revealed recent methamphetamine use and current rectal gonorrheal or chlamydial infection to be associated with HIV infection. The data confirm diverse sexual networks and substantial sexual risk-taking, despite relatively high levels of education and HIV-related knowledge. In addition to promoting partner reduction and more consistent condom and lubricant use, prevention efforts must also address substance abuse.

HIV prevalence and risk behaviours among injecting drug users in six indonesian cities implications for future HIV prevention programs

BackgroundThe HIV prevalence among injecting drug users (IDUs) in Indonesia reached 50% in 2005. While drug use remains illegal in Indonesia, a needle and syringe program (NSP) was implemented in 2006.MethodsIn 2007, an integrated behavioural and biological surveillance survey was conducted among IDUs in six cities. IDUs were selected via time-location sampling and respondent-driven sampling. A questionnaire was administered face-to-face. IDUs from four cities were tested for HIV, syphilis, gonorrhoea and chlamydia. Factors associated with HIV were assessed using generalized estimating equations. Risk for sexual transmission of HIV was assessed among HIV-positive IDUs.ResultsAmong 1,404 IDUs, 70% were daily injectors and 31% reported sharing needles in the past week. Most (76%) IDUs received injecting equipment from NSP in the prior week; 26% always carried a needle and those who didn’t, feared police arrest. STI prevalence was low (8%). HIV prevalence was 52%; 27% among IDUs injecting less than 1 year, 35% among those injecting for 1–3 years compared to 61% in long term injectors (p < 0.001). IDUs injecting for less than 3 years were more likely to have used clean needles in the past week compared to long term injectors (p < 0.001). HIV-positive status was associated with duration of injecting, ever been imprisoned and injecting in public parks. Among HIV-infected IDUs, consistent condom use last week with steady, casual and commercial sex partners was reported by 13%, 24% and 32%, respectively.ConclusionsAlthough NSP uptake has possibly reduced HIV transmission among injectors with shorter injection history, the prevalence of HIV among IDUs in Indonesia remains unacceptably high. Condom use is insufficient, which advocates for strengthening prevention of sexual transmission alongside harm reduction programs.

Addressing the high prevalence of gonorrhoea and chlamydia among female sex workers in Indonesia: results of an enhanced, comprehensive intervention

Objectives The authors developed a comprehensive STI-control programme to decrease gonorrhoea and chlamydia prevalence, and increase consistent condom use among brothel-based sex workers in Indonesia. Methods The STI-control programme for brothel-based sex workers in Bintan Island (Riau Islands) and Salatiga (Central Java) included (1) provision of adequate drugs for gonorrhoea and chlamydia as periodic presumptive treatment (PPT) followed by syndromic treatment; (2) condom-use promotion by involving the local community and ensuring sufficient condom supply. Endocervical samples were collected and tested for gonorrhoea and chlamydia by PCR. Cross-sectional assessments of gonorrhoea and chlamydia prevalence, and consistent condom use with clients in the last week were made at several time points for sex workers attending the STI clinic. Results 580 sex workers participated in the programme. A steady decrease in prevalence was observed for gonorrhoea (36.1–7.6%) and chlamydia (33.7–10.2%) (both p<0.01) among sex workers in Bintan from March 2008 until June 2009. Sex workers in Salatiga showed a sharp initial decrease in prevalence, followed by an increase after provision of the old drug regimen. Gonorrhoea and/or chlamydia prevalence among those who had received at least one PPT round was lower compared with that in newcomers (p<0.01). The proportion of sex workers reporting consistent condom use doubled to 40% in June 2009 compared with November 2007 (p<0.01). Conclusion The STI-control programme was effective in reducing infection prevalence and increasing condom use among sex workers. This intervention has been scaled up and may decrease national STI levels and reduce HIV transmission.

Sexual risk taking, sexually transmitted infections and HIV prevalence among four "high-risk" occupational groups of Indonesian men.

Objectives: This article reports new surveillance data on the prevalence of sexual risk taking, HIV and other sexually transmitted infections (STI) among four occupational groups of Indonesian men thought to be at elevated risk of infection. Methods: Behavioural survey data were collected from 3008 men in 11 cities, among whom 2158 men were tested for HIV and syphilis and 1950 for gonorrhoea and chlamydia. Risk factors for STI were assessed using multivariable logistic regression. Results: Thirty-six per cent of men had sex with a female sex worker (FSW) in the previous year and 20% with non-marital female partners. Consistent condom use was low with both sex workers (17%) and other non-marital partners (13%). HIV prevalence was 2% in Papua and less than 1% elsewhere, but was for the first time detectable in a non-core transmitter male population outside of Papua. STI rates were high for a non-core transmitter group, especially syphilis. Truck drivers were the most at risk. Multivariable analyses revealed exposure to FSW and inconsistent condom use, along with geographical location (Papua vs non-Papua) and unobserved factors associated with certain occupational groups, to be key risk factors for STI infection. Conclusions: The results confirm that men in the four occupational groups are reasonable proxies for “high-risk men” for surveillance purposes in Indonesia. Although HIV prevalence was low, the extent of sexual risk taking and the moderately high levels of STI among these men, along with rising HIV rates among FSW, indicate the potential for HIV/AIDS transmission in Indonesia to accelerate.
