1 Multi-level Correlates of Adolescent Sexual Behavior and Risk for STD Kathleen A. Ethier, Ph.D. Christine J. De Rosa, Ph.D., Deborah H. Kim, MPH, Abdelmonem Afifi, Ph.D., Peter R. Kerndt, MD

2 Social/Ecological Model Individual Personal relationships: Family, peers, partners Institutions and Communities: School, Health Care Society and Policy

3 Multiple behaviors pose risk for HIV/STD and teen pregnancy Early age at first intercourse Multiple/new sex partners Unprotected intercourse Lack of STD screening Niccolai, et al. 2004; Fortenberry et al.,2005; Celentano, 2004; Weller & Davis, 2005; Paz-Bailey et al, 2005; Coker, et al., 1994; Van Ranson, et al., 2000; Kaestle, et al., 2005

4 Multiple social context level factors impact adolescent sexual behavior Parental monitoring Parental communication Family relationship quality School involvement After school supervision Health care services –School-based health services and referrals, STD screening, condom and contraceptive availability) Forehand et al., 1997; Miller, Kotchick & Forehand, 1999; Romer et al., 1999; Baker et al., 1999;Dittus, Jaccard & Gordon, 1999; Holtzman & Rubison, 1995; Miller, Levin, Whitaker & Xu, 1998; Romer et al., 1999; Whitaker, Miller, May & Levin, 1999; Karofsky et al., 2000; Hutchinson et al 2003; McNeely et al, 2002; Billy, Brewster, & Grady, 1994; Lammers et al., 2000; Manlove, 1998; McNeely et al., 2002; Bonny et al., 2000; Lonczak, 2002; Cohen et al., 2002; Miller et al., 1998; Sabo et al., 1998; Kirby, 2002

5 The Questions for STD Prevention Do multiple social context factors relate to sexual behavior that puts adolescents at risk for STD? Do relationships vary by specific behavior? Are there particular social context factors or combinations of factors that, if intervened on, will give us the most impact on STD risk?

6 Methodology Classroom-based survey of high school students (n=5930). Classrooms were randomly selected from a list identified as classes all students would have to take (e.g., social studies) and would contain a single grade level. Parental consent was obtained for all students under 18 years. Survey took approximately 30 minutes. Questions covered four social context areas (family, school, health care and community factors) and a wide range of sexual behaviors.

7 Analyses Step 1 A set of bivariate logistic regression analyses for each of five STD risk factors –ever had sex (yes/no) –consistent condom use –4 or more lifetime partners (yes/no) –new partner in the last 3 months (yes/no) –ever tested/treated for an STD (yes/no) 21 social context factors –7 family factors –5 school factors –4 health care factors –6 community factors

8 Analyses Step 2 A series of logistic regression analyses for each of the five STD risk factors –Included any social context factor that was significant at p<.10 in bivariate analyses –Controlled for age, race/ethnicity, and gender

9 Sample Characteristics Race/ethnicity –Latino = 76.6% –African American = 11.4% –White = 2.1 % –Other = 9.8% Grade –9th = 24.1% –10th = 19.7% –11th = 24.3% –12th = 31.9% Gender –Male = 44.7% –Female = 55.3% 67.4% received free or reduced lunch.

10 STD Risk Behavior 47.7% have ever had sex 40.0% used condoms every time/last 3 months* 18.3% have had 4+ lifetime sex partners* 12.3% had a new partner/last 3 months* 22.7% ever screened or treated for an STD* * Among those who had ever had sex

17 Level- specific Messages Family factors have high impact. –Monitoring is not only related to initiation of sexual activity, but more monitoring is related to fewer sex partners. –Content specific communication is important. Supervision is more important than where kids are supervised (school, community or home).

18 Multi-level Messages No single level or factor is sufficient to prevent most risk behaviors. Multiple levels of intervention could provide synergistic effects.
