Background: Early marriage is a public health problem that violates the adolescent girl's 
basic human rights. The Sustainable Development Goals had incorporated early marriage in 
target 5.3, aiming to eliminate by 2030. Aim of the study was to evaluate the effect of 
empowerment program on knowledge, attitude and practice of rural adolescent girls 
regarding health consequences of early marriage. Subjects and Method: Design: A quasiexperimental research design was utilized. Setting: The study was conducted in two 
preparatory schools at Zagazig city. Subjects: A sample of 100 female students randomly 
selected from east and west educational administrations. Tools of data collection: A selfadministered questionnaire consists of four parts; socio demographic characteristics, 
knowledge regarding health consequences of early marriage, attitude toward early marriage 
and healthy practices of adolescent girls. Results: The study results revealed that there were 
statistically significant improvements in knowledge, attitude and practice of adolescent girls 
regarding health consequences of early marriage after the program (p < .0001). The result 
also showed that knowledge score was positively correlated to attitude score (r = .379) and 
practices score (r = .399) at post program phase. Conclusion: The program's implementation 
was shown to be successful in improving adolescent girls' knowledge, attitude and practices 
regarding health consequences of early marriage. Recommendations: Further researches 
should continue to identify determinants of early marriage to assist in building more girlcentered interventions and norms change interventions that empower adolescent girls, 
particularly, in rural areas in order to advocate for themselves against child marriage.
