Identify four potential risk factors that may lead adolescents to engage in sexual behavior resulting in teenage pregnancy.

1. Lack of comprehensive sex education: Adolescents who do not receive accurate and comprehensive information about sexual health and contraception may be more likely to engage in risky sexual behavior.

2. Peer pressure: Adolescents may feel pressure from their peers to engage in sexual activity, especially if they believe it will make them more popular or accepted.

3. Low self-esteem: Adolescents with low self-esteem may seek validation through sexual activity, leading them to engage in risky behavior without considering the potential consequences.

4. Family dynamics: Adolescents who come from unstable or dysfunctional family environments may be more likely to engage in risky sexual behavior as a way to seek attention or escape from their home life.
