Adolescent Risk Behaviors Lesley Cottrell, PhD West Virginia University, Department of Pediatrics Section Chief: Epidemiological, Psychosocial, & Behavioral Research
Rationale for Prevention among Youth • Adolescence is a time… • of new-found freedom and exploration • when behaviors are established that have both an immediate and long-lasting health impact. • to provide prevention messages as patterns of health behaviors are being established.
Overview • Epidemiology • Current State of Science • Intervention Research • Emerging Issues • Interventions in the pipeline

HIV, STI, and Pregnancy Among Youth • Of the 19 million new STIs that occur in US each year, 48% are among young people ages 15 – 24. • 15% to 30% of new HIV cases occur among individuals under 25 years of age. • There were 757,000 pregnancies in 2002 among 15-19 year olds. • African American and Hispanic/Latino youth are disproportionately affected by these outcomes.
Sexually Transmitted Disease • 15 – 24 year-olds acquire nearly 50% of all new STDs. • 9.1 million cases of STDs occur among 15-24 year olds each year. • Increased rates of some STDs, primarily because of improved screening.

STDs • Greater risk for STDs than people in other age groups. • Female youth and youth of color are disproportionately affected. • African Americans have the highest rates of sexually transmitted diseases (STDs). • In 2005, compared to Whites, African Americans were about: • 18 times as likely to have gonorrhea • 7 times as likely to have Chlamydia • 5 times as likely to have syphilis. • The presence of certain STDs can increase one’s chances of contracting HIV 3- to 5-fold.
Adolescent Pregnancy • Decrease in rates of pregnancy overall • smaller decreases in ethnic minority youth; • most recent data suggest rates are not continuing to decrease and in most states have remained level. • 831,000 pregnancies occur each year among 15-19 year olds.

Critical Issues Affecting Disparities • Behavioral Factors • Early sexual debut • Multiple sex partners • High risk sexual behavior • Contextual Factors • Cultural beliefs about sexuality • Gender roles • Access to health care services • Structural Factors • Social, economic and race based inequality • Social Networks • Black young adults at high risk even when their behaviors are normative • Factors other than individual risk behaviors and covariates appear to account for racial disparities

Identifying Effective Interventions:Prevention Research Synthesis (PRS) Project • Goal: • Review and synthesize cumulative body of evidence from the scientific research literature to help inform policy decisions, programmatic efforts, and future research • Identify evidence-based behavioral interventions • Results: • 31 interventions identified as “best evidence” • 7 were for youth • Ongoing review for earlier and later years
PRS Project Website Fact Sheet: • Target population • Intervention • Research study • Key findings
Interventions Identified by PRS for Youth (n=15) • Best Evidence (n=7) • Becoming a Responsible Teen (BART) (St. Lawrence, 1995) • Be Proud! Be Responsible! (Jemmott, 1992) • Focus on Kids (FOK) + Informed Parents and Children Together (ImPACT) (Wu, Stanton, 2003) • Sistas, Informing, Healing, Living and Empowering (SiHLE) (DiClemente, 2004) • Sisters saving Sisters (Jemmott, 2005) • Choosing Life: Empowerment, Actions, Results (CLEAR-in person) Rotheram-Borus, 2004) • ¡Cuídate! (Take Care of Yourself) (Villarruel, 2006)
Interventions Identified by PRS for Youth Promising Evidence (5) • Safer Sex– (Shrier, 2001) • Focus on Kids (FOK) (Stanton, 1996) • Intensive AIDS Education (Magura, 1994) • Street Smart (Rotheram-Borus, 2003) • Together Learning Choices—(Rotheram-Borus, 2001) Compendium (3) • AIDS Community Demonstration Projects (Community PROMISE) (ACDP, 1999) • Reducing the Risk (School based) • Get Real about AIDS 1992 (School based)
Common Intervention Messages • peer opinion leaders to assist in program delivery • active social learning methods, involving role plays, behavioral rehearsal, and group discussion • inclusion of parents through homework and other activities • the same risk and protective factors may predict various problems • risk and protective factors may be found in the environment as well as in the individual • developmental needs, processes, and tasks should be taken into account
