Biological Factors in Adolescent Risky Behaviors

What are the biological factors among all adolescents that could contribute to risky behaviors in adolescence?

What are the key biological factors that can influence risky behaviors in adolescents?


Adolescent risky behaviors can be influenced by several biological factors including the uneven development of the brain.

Among adolescents, one key biological factor that can contribute to risky behaviors is the rapid and uneven development of the brain, specifically in the neural reward center. During adolescence, this part of the brain undergoes significant growth and refinement, which can lead to increased risk behaviors. This growth is typically more pronounced and accelerates at a quicker pace than other parts of the brain regulating self-control and assessing potential danger, which can result in adolescents engaging in risky behaviors as they are more prone to valuing immediate rewards over potential long-term consequences.

Furthermore, puberty is a significant biological factor during adolescence. The different rates of physical development brought about by puberty can result in varying mental and emotional health outcomes which may incite risk-taking behavior. For instance, early maturing boys and girls may be at greater risk for substance abuse, early sexual activity, depression, eating disorders, while late maturing individuals may struggle with self-consciousness, depression, and conflict.

Lastly, genetic predispositions may also contribute to the probability of risk-taking behavior. Some adolescents may possess genetic tendencies towards impulsivity and emotional instability, which can increase the likelihood of participating in risky behaviors.
