Early sexual intercourse is not an unplanned experience for many teens. Decisions about initiation are strongly bound to social context with peers playing an important role in creating a sense of normative behavior. Specific components of peer norms impact the process of sexual initiation in both positive and negative ways. Interventions aimed at delaying the onset of sexual initiation need to focus on cohort norms as well as on an individual's perceptions and behaviors.

These new follow-up data confirm our previous finding that the TLC regimen of chelation therapy is not associated with neurodevelopmental benefits in children with blood lead levels between 20 and 44 microg/dL (0.96-2.17 micromol/L). These results emphasize the importance of taking environmental measures to prevent exposure to lead. Chelation therapy with succimer cannot be recommended for children with blood lead levels between 20 and 44 microg/dL (0.96-2.12 micromol/L).
