Child abuse presents major social and public health challenges, resulting in numerous negative outcomes for children and adolescents. This study examines the effects of child abuse on children aged 3-13 years in the Ikotun local government area of Lagos State. Employing a descriptive research design, a sample of 150 children was selected using a convenience sampling technique. Data collection was carried out through a semi-structured questionnaire with a reliability index of 0.858. Three research questions were analyzed using descriptive statistics, while one hypothesis was tested through inferential statistics, specifically the Pearson correlation coefficient, significance level of 0.05. at a The findings revealed that sexual abuse is the most common form of child abuse, with contributing factors including caregivers' lack of self-control and inadequate penalties for offenders. The primary effects of child abuse identified were unwanted pregnancies and early marriages. Hypothesis testing demonstrated a significant relationship between respondents' gender and the impact of child abuse (P=0.010, P>0.05). Recommendations based on these findings include launching social awareness campaigns to educate the public on child abuse and its consequences, enacting and enforcing effective child protection laws, and implementing strict penalties for perpetrators.
