Child abuse remains a critical issue in Indonesia. Cases have been tracked in real time through the Online Information System for the Protection of Women and Children (SIMFONI-PPA) since 2016; however, long-term trends have not been comprehensively analysed. This study examined national child abuse trends in Indonesia and explored health promotion strategies for prevention. Secondary data from SIMFONI-PPA were analysed to identify trends in abuse types, victim profiles, perpetrator profiles, and locations. A literature review was conducted to identify prevention strategies employing a health promotion framework grounded in the Ottawa Charter. Findings showed a steady increase in reported child abuse cases. Sexual violence was the most reported abuse, 2-3 times higher than physical or psychological violence and several times more than trafficking or exploitation. Adolescent girls (approximately 70% of victims), aged 13-17 (over 50% victims), were the most affected; about one-third of victims were attending junior high school. Perpetrators were known to the victims, such as lovers or peers (about a quarter of cases), and most incidents occurred at home (around half of reported cases). Indonesia has implemented several prevention strategies, including policy reform, education, and community-based efforts. The rising trend of child abuse in Indonesia underscores the urgent need for multisectoral, context-sensitive interventions focused on improving data collection, service access, and reducing stigma. Future research should explore socio-cultural factors and evaluate the effectiveness of existing prevention programs. © The Authors, published by EDP Sciences, 2025.
