RESUMEN
BACKGROUND: Street children's level of knowledge, attitudes, and practice (KAP) regarding sexually transmitted infections (STIs) and HIV-related diseases remains a challenge since it is difficult to reach all key populations. This study aims to provide an overview of the findings of STI cases and their association with the KAP of street children in Jakarta and Banten. METHODS: We conducted a cross-sectional study on 259 male street children (aged 10 -21 years old). We collected the data through questionnaire interviews, history taking, physical examination, and specimen collection for STI and HIV testing. RESULTS: 5.8% (n = 15) STI cases were discovered, consisting of Hepatitis B (n = 6), Hepatitis C (n = 1), HIV (n = 2), Chlamydia (n = 3), Syphilis (n = 1), and Gonorrhea (n = 1). Buskers (44.4%) and other occupations like helping parents sell their wares, parking lot attendants, shoe shiners, or gathering (44.8%) dominated the sociodemographic characteristics. Condomless sex predominated risky sexual behavior, despite some subjects already having good knowledge. CONCLUSION: Sociodemographic characteristics and the KAP of street children in Indonesia are varied. The association between the KAP level and STI cases in street children is challenging to describe. Further studies covering more areas in Indonesia are required.
