Adolescence is a crucial developmental stage that has long-term effects on a person's health and well-being as well as the welfare of society at large. Children learn how to understand abstract concepts, form moral beliefs, and create and sustain fulfilling relationships during adolescence. During adolescence, young people go through a variety of transformations as they become physically adults. Changes in the youth begin with the appearance of secondary sexual traits. Dynamic brain development that is distinguished by interaction with social circumstances throughout adolescence impacts the talents that a person carries into adulthood. In girls, there is the onset of the menstrual cycle, which leaves a big impact on their body. Adolescents across the globe have a lifestyle risk index comprising risky drug and alcohol consumption, unprotected sex, sleep duration, and smoking, which is a fair to good indicator of medical conditions connected to lethal (performing suicide and self-harm) and non-fatal (major depressive disorders and severe psychological distress) diseases. According to the findings of this study, the lifestyle risk index is a valuable summary indicator in the context of teenage health promotion and noncommunicable disease prevention. Adolescent lifestyle risk variables were discovered to cluster, giving additional backing for the deployment of numerous health behavior modification interventions rather than those having a single behavior emphasis.
