Understanding human sexual networks: a critique of the promiscuity paradigm

Factors influencing HIV-risk perception among MSM students at a university in Durban, South Africa

Risk perception is embedded in attitudes and beliefs that determine how one ultimately behaves. In relation to HIV-risk behaviours, risk perception is a key dimension in most health behaviour models used to construct health promotion campaigns. This study aimed to understand HIV-risk perception and associated factors among men who have sex with men (MSM). The qualitative data used in this study came from 15 in-depth interviews with MSM studying at the University of KwaZulu-Natal in Durban, South Africa. The findings show that MSM perceive themselves to be at risk for HIV due to their awareness of the main routes of infection. This perception exists because HIV has affected them through the loss of close family members. With each sexual encounter, risk perception changed based on factors such as the sexual role being assumed (insertive versus receptive), the socio-economic status of the partner, perceived level of discriminatory dating patterns, and the use of preventive measures. High levels of risk perception among the men did not translate into positive attitudes towards condoms as many of them preferred to have unprotected sex with trusted partners. Despite perceiving their risk of HIV infection to be high, MSM continue to engage in multiple sexual partnerships and high partner turnover. However, the men in this study were keen to protect their health; with time, they have developed more positive attitudes towards HIV and they understand that it is possible to protect oneself before and after infection.

Factors associated with numbers of client partners of female sex workers across five districts in South India

BACKGROUND

This study investigated the structural-environmental and individual-level social factors associated with the numbers of commercial sex clients of female sex workers (FSWs) per month (CPM).

METHODS

Data were analyzed from cross-sectional surveys of FSWs in 5 districts in Karnataka state, India (2004-2005). Bivariate and multivariable negative binomial regression models with generalized estimating equations were constructed for each district. Normalized weights were used to account for complex sampling design.

RESULTS

Median (average) CPM varied significantly (P < 0.001) across districts, from 40.0 (56.9) CPM in the district with the highest immunodeficiency virus prevalence (33.9%) to 16.0 (26.1) in the district with the lowest prevalence (9.7%). In multivariable analysis, there was a significant positive association between rates of CPM and sex work as sole income in 4 districts (adjusted incidence rate ratios, AIRR: [95% confidence intervals]: AIRR: 1.3 [1.0-1.7], P < 0.005-1.7 [1.2-2.5], P < 0.01); age, typology (place of solicitation), and marital status were significantly associated with CPM in 3 districts, with an inverse association between age and CPM (P < 0.01). FSWs soliciting clients in brothels had higher rates of CPM than home-based FSWs in 2 districts (AIRR: 1.5 [1.1-2.0]-1.6 [1.0-2.7], P < 0.05), whereas public places-based FSWs had higher rates in 1 district (AIRR: 1.4 [1.1-1.8], P < 0.01); cohabiting FSWs had higher rates than married FSWs in 3 districts, whereas single FSWs had higher rates in one district.

CONCLUSIONS

These results provide support for the continued development of structural core group interventions that address common elements of sex work placing FSWs at higher risk for immunodeficiency virus, as well as geographically focused programs that account for local differences in sexual structure.

HIV status differences in venues where highly sexually active gay and bisexual men meet sex partners: results from a pilot study

Highly sexually active men who have sex with men (MSM) are a critical population in which to provide HIV prevention and education. To inform the tailoring and placement of such services, this study reports on HIV status differences in nine venues where 50 highly sexually active MSM (defined as those who had nine or more male partners in the past 90 days) met recent male sex partners. HIV-positive men (95%) were significantly more likely than HIV-negative/unknown status men (68%) to have used the Internet to meet partners but were less likely to meet partners in bars/clubs (37% vs. 71%). Although both HIV-positive and HIV-negative/unknown status men reported a sizable portion of their total partners from the Internet (55% and 29%, respectively), HIV-positive MSM also gravitated toward meeting partners through sexual networks (private sex parties and via other sex partners), whereas HIV-negative/unknown status also gravitated toward gay bars/clubs and public cruising. Overall, HIV-positive men were more likely to report unprotected anal sex than to HIV-negative/unknown status men. Among HIV-negative/unknown status men, the highest rates of unprotected sex were with men they met online (20% of online partners) and through other sex partners (25% of these partners). Efforts targeted toward highly sexually active HIV-negative/unknown status men might be best positioned online and in gay bars/clubs, whereas those tailored for highly sexually active HIV-positive men may consider targeting the Internet and peers/sexual networks.
