<![CDATA[Smoking behavior among adolescents is one of the health problems commonly found in society and continues to increase. This study aims to determine the relationship between adolescents' knowledge of the dangers of smoking and smoking behavior in RT 04, Pegadungan Village, West Jakarta. This study used an analytical correlation design with a cross-sectional approach. The research sample consisted of 116 respondents selected using a purposive sampling technique. The research instruments used a knowledge questionnaire on the dangers of smoking consisting of 10 statements and a smoking behavior questionnaire consisting of 30 statements, both of which had met the validity and reliability tests. Data were analyzed using the Chi-Square test. The results showed that out of 116 respondents, the majority of adolescents with good knowledge had low smoking behavior (68.5%), while adolescents with sufficient knowledge (58.8%) and poor knowledge (85.7%) tended to have high smoking behavior. The Chi-Square test results showed a significant relationship between knowledge of the dangers of smoking and smoking behavior (p = 0.000; p < 0.05). In conclusion, the better the level of adolescents' knowledge about the dangers of smoking, the lower their tendency to engage in smoking behavior. Therefore, continuous educational efforts for adolescents, along with the involvement of families and schools in providing understanding about the dangers of smoking, are needed to prevent the formation of smoking behavior among adolescents.]]>
