| Adolescence is a stage in human life between childhood and adulthood when physical, mental and psychosocial traits changed rapidly. At this stage, adolescents try new things because of their increased curiosity. These changes can cause many problems, and one of them is in reproductive health. The study was conducted to obtain information about sexual behavior, and the relationship between their knowledge and attitude on reproductive health of students aged 17-19 years (n=395). It was a cross sectional study. Results showed that 8.4% students had sexual intercourse. Bivariate analysis of Pearson Chi-Square showed that knowledge and attitude of reproductive health had no significant correlation with sexual behavior. |
