Sociodemographic Characteristics, Risk Groups, and Sexually Transmitted Infections

Abstract

Sexually transmitted infections (STIs) remain a public health concern. This cross-sectional study examined associations of sociodemographic characteristics and recorded risk groups with STI diagnoses using 201 patient records from a community health center in Mataram, Indonesia, in 2025. Data were analyzed using chi-square tests. Men who have sex with men comprised the largest recorded risk group (161; 80.1%). The most frequent diagnoses were gonorrhea (95; 47.3%), syphilis (69; 34.3%), bacterial vaginosis (20; 10.0%), and HIV (17; 8.5%). Age, employment, sex, and marital status were associated with STI diagnosis categories, whereas education was not (p = 0.348). Risk-group classification was also associated with diagnosis (p < 0.001). These findings describe patterns among service users rather than population-level risks.
