As the HIV/AIDS epidemic and the spread of sexually transmitted infections (STIs) in China has come to the forefront of public health attention, female sex workers (FSWs) and their clients (CFSWs) are becoming increasingly important to HIV/STI prevention efforts. This secondary analysis uses data abstracted from the Chinese Health and Family Life Survey 1999-2000 to report prevalence rates of two STIs as well as sexual risk behaviors for CFSWs - men who paid for sex with FSWs in the past 12 months - in comparison with men who had not patronized FSWs. Among 1879 Chinese CFSWs who completed anonymous interviews and urine testing, 152 (6.3%, weighted) said they had paid for sex in the past 12 months and 18.8% of CFSWs (weighted) tested positive for gonorrhea. CFSWs were 10 times more likely to have an STI (either self-reported or tested) than non-client Chinese men, and they were equally likely to use condoms inconsistently with their spouses. This study highlights the importance of studying CFSWs who use condoms inconsistently and do not practice safe sex with their spouse as a potential bridge population. Prevention and intervention efforts should target this bridge population and include education on HIV/AIDS and STI transmission, condom promotion, marriage counseling, destigmatization of HIV and STIs, and promotion of STI diagnosis and treatment.

Summary This study aims to describe and compare the gender-specific prevalence of chlamydia and gonorrhea, sexual behaviors and experiences, and risk factors associated with STIs among migrants vs. rural as well as urban residents in China. Data were abstracted from the Chinese Health and Family Life Survey conducted from 1999 to 2000 which provided a nationally representative adult (ages 20 to 64) sample. STI results were determined using a urine-based technology. Of the samples, the prevalence of chlamydia for migrant women was triple that of rural non-migrant women. Migrants were more likely to engage in STI-associated risk behaviors than non-migrants (e.g., receiving money for sex). Being female was a significant risk factor of STIs among migrants. The high STI prevalence among migrants highlighted the urgent need to implement comprehensive sexual behavior prevention and intervention programs targeting the cultural, social and structural needs for migrants in the city, especially female migrants.

Because men account for nearly half of the HIV cases in South Africa, it is critical to understand the contexts in which they live and the behaviors in which they engage. The purpose of this study was to describe and examine gender differences in intimate partner violence on substance abuse, sexual risks, and depression among a sample of South Africans in Cape Town. We found that recent exposure to intimate partner violence among men was associated with all forms of drug use, whereas women who were recently abused were more likely to suffer from depression and problem drinking. We also found high levels of problem drinking among both men (58%) and women (42%). Men were more likely to use drugs. Exposure to community violence increased sexual risk behaviors among men. Overall, these gender differences have important implications for alcohol and drug prevention strategies as they relate to HIV transmission risk.
