RESUMO

PURPOSE: While cross-sectional studies have shown that teen dating violence (TDV) victimization is linked to sexual risk behavior (SRB), the pathway between these variables is not well-understood. To address this knowledge gap, we explore the mediating role of self-efficacy to refuse sex in the longitudinal relationship between physical TDV victimization and subsequent SRB among adolescents. METHODS: Self-report data from three prior longitudinal studies were harmonized to create a single aggregated sample of primarily racial and ethnic minority adolescents (N = 4,620; 51.4% Hispanic, 38.5% Black, and 58% female) from 44 schools in the southwest U.S. Participants' physical TDV victimization at baseline (seventh and eighth grade), self-efficacy to refuse sex at 12-month follow-up, and SRB at 24-month follow-up was tested using mediation models with bias corrected bootstrapped confidence intervals. All regression models controlled for age, race, parental education, SRB at baseline, and intervention status. RESULTS: Physical TDV victimization at baseline was associated with refusal self-efficacy at 12 months and SRB (e.g., frequency of vaginal and oral sex, lifetime number of vaginal sex partners, and number of vaginal sex partners in the past three months without condom use) at 24 months. Refusal self-efficacy mediated the link between physical TDV victimization and increased risk of SRB for females and males, to a lesser extent. DISCUSSION: Adolescent victims of physical TDV report diminished self-efficacy to refuse sex, predisposing them to engage in SRBs, including condomless sex.

RESUMO

Being a victim of sexual violence (SV) is generally believed to be associated with subsequent sexual risk behavior (SRB) during adolescence. While this assumption makes intuitive sense, it is based on methodologically limited research, including a reliance on cross-sectional data. To address this gap in research, we test whether experiencing SV victimization in early adolescence is associated with self-reported SRB approximately two years later. The sample comprised 4,618 youth (58% female; 52% Hispanic; 39% Black) attending 44 schools in the southern United States. Self-reported data were collected using an audio computer-assisted self-interview (ACASI). Baseline data were collected when students were in 7th or 8th grade and follow-up data were collected approximately 24 months later when students were in 9th or 10th grade. Indices of SRB included behaviors related to oral, vaginal, and anal sex (e.g., number of partners, number of times without a condom). Girls, but not boys, who reported SV victimization at baseline reported engaging more frequently in all oral and vaginal SRBs at 24 month follow-up compared to their non-victimized female counterparts. Additionally, girls reporting SV victimization reported more anal sex partners than non-victimized girls. Girls who are victims of SV engage in significantly more SRB by early high school placing them at greater risk to contract STIs and become pregnant. Victims of SV should be screened for SRB and provided access to the appropriate resources. Teen pregnancy and STI prevention planning should consider SV victimization in their strategy planning.

RESUMO

Me & You: Building Healthy Relationships (Me & You) is a multilevel, technology-enhanced adolescent dating violence (DV) prevention program that aimed to reduce DV among ethnic-minority, early adolescent, urban youth. A group-randomized control trial of Me & You, conducted with 10 middle schools from a large urban school district in Southeast Texas in 2014-2015, found it to be effective in reducing DV perpetration and decreasing some forms of DV victimization. Economic evaluations of DV interventions are extremely limited, despite calls for more economic analyses to be incorporated in research. We help fill this gap by evaluating the cost-effectiveness from the payer and societal perspectives of implementing the Me & You program. Using cost data collected alongside the Me & You group-randomized trial, we computed incremental cost-effectiveness ratios. Our primary outcome was "any DV perpetrated" within 12 months of the intervention. We conducted a cost-benefit analysis beyond the intervention endpoint by using literature estimates of per-victim lifetime costs of DV. We performed sensitivity analyses to assess effects of uncertain parameters. Under the base-case scenario, the cost of the Me & You curriculum compared to the standard curriculum was $103.70 per-student from the societal perspective, and the effectiveness was 34.84 perpetrations averted, implying an incremental cost per perpetration averted of $2.98, which ranged from $0.48 to $73.24 in sensitivity analysis. Thus, we find the Me & You curriculum is cost-effective and cost-saving in most scenarios. Policymakers should carefully consider school-based DV prevention programs, and cost data should be regularly collected in adolescent prevention program evaluations.

RESUMO

Recent research has suggested the importance of understanding for whom programs are most effective (Supplee et al., 2013) and that multidimensional profiles of risk and protective factors may moderate the effectiveness of programs (Lanza & Rhoades, 2012). For school-based prevention programs, moderators of program effectiveness may occur at both the individual and school levels. However, due to the relatively small number of schools in most individual trials, integrative data analysis across multiple studies may be necessary to fully understand the multidimensional individual and school factors that may influence program effectiveness. In this study, we applied multilevel latent class analysis to integrated data across four studies of a middle school pregnancy prevention program to examine moderators of program effectiveness on initiation of vaginal sex. Findings suggest that the program may be particularly effective for schools with USA-born students who speak another language at home. In addition, findings suggest potential positive outcomes of the program for individuals who are lower risk and engaging in normative dating or individuals with family risk. Findings suggest potential mechanisms by which teen pregnancy prevention programs may be effective.

RESUMO

BACKGROUND: Although schools often implement evidence-based sexual health education programs to address sexual and reproductive health disparities, multiple factors may influence program effectiveness. METHODS: Using student-reported perceived impact measures as a proxy for program effectiveness, we employed a socio-ecological approach to examine student, teacher, school, and district factors associated with greater perceived impact of It's Your Game (IYG), an evidence-based middle school sexual health education program. The student sample was 58.7% female, 51.8% Hispanic, mean age 13.2 years, from 73 middle schools. We assessed students' (N = 4531) perceived impact of IYG on healthy decision-making (α = 0.75) and sexual communication (α = 0.71); satisfaction with IYG activities and teacher; and demographics. We assessed teachers' (N = 56) self-efficacy to teach IYG, perceived administrative support, implementation barriers, and demographics. School and district data were abstracted from state records. We used multilevel logistic regression to estimate associations between independent variables and student-reported perceived impact. RESULTS: In final multivariate models, students' demographics (sex, ß = 0.06, SE = 0.015), satisfaction with IYG (ß = 0.21, SE = 0.012), and their IYG teacher (ß = 0.18, SE = 0.013) (all p = .000) were significantly associated with perceived impact on healthy decision-making. Similar findings resulted for sexual communication. No other variables were significantly associated with perceived impact. CONCLUSIONS: Helping schools select age-appropriate, culturally relevant programs, and facilitate supportive learning environments may enhance the perceived impact of sexual health education programs.

RESUMO

Objectives. To test the efficacy of Me & You, a multilevel technology-enhanced adolescent dating violence (DV) intervention, in reducing DV perpetration and victimization among ethnic-minority early adolescent youths. We assessed secondary impact for specific DV types and psychosocial outcomes.Methods. We conducted a group-randomized controlled trial of 10 middle schools from a large urban school district in Southeast Texas in 2014 to 2015. We used multilevel regression modeling; the final analytic sample comprised 709 sixth-grade students followed for 1 year.Results. Among the total sample, odds of DV perpetration were lower among intervention students than among control students (adjusted odds ratio = 0.46; 95% confidence interval = 0.28, 0.74). Odds of DV victimization were not significantly different. There were significant effects on some specific DV types.Conclusions. Me & You is effective in reducing DV perpetration and decreasing some forms of DV victimization in early middle-school ethnic-minority students.

RESUMO

INTRODUCTION: Diffusion of sexual health evidence-based programs (EBPs) in schools is a complex and challenging process. iCHAMPSS ( CHoosing And Maintaining effective Programs for Sex education in Schools) is an innovative theory- and Web-based decision support system that may help facilitate this process. The purpose of this study was to pilot-test iCHAMPSS for usability and short-term psychosocial impact. METHOD: School district stakeholders from across Texas were recruited ( N = 16) and given access to iCHAMPSS for 3 weeks in fall 2014. Pre- and posttests were administered to measure usability parameters and short-term psychosocial outcomes. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test. RESULTS: Most participants reported that iCHAMPSS was easy to use, credible, helpful, and of sufficient motivational appeal. iCHAMPSS significantly increased participants' self-efficacy to obtain approval from their board of trustees to implement a sexual health EBP. Positive, though nonsignificant, trends included increased knowledge to locate EBPs, skills to prioritize sexual health education at the district level, and ability to choose an EBP that best meets district needs. CONCLUSIONS: iCHAMPSS is an innovative decision support system that could accelerate uptake of EBPs by facilitating diffusion and advance the field of dissemination and implementation science for the promotion of sexual health EBPs.

RESUMO

Much is known about the prevalence and correlates of dating violence, especially the perpetration of physical dating violence, among older adolescents. However, relatively little is known about the prevalence and correlates of the perpetration of cyber dating abuse, particularly among early adolescents. In this study, using a predominantly ethnic-minority sample of sixth graders who reported ever having had a boyfriend/girlfriend (n = 424, 44.2 % female), almost 15 % reported perpetrating cyber dating abuse at least once during their lifetime. Furthermore, using a cross-sectional design, across multiple levels of the socio-ecological model, the individual-level factors of (a) norms for violence for boys against girls, (b) having a current boyfriend/girlfriend, and (c) participation in bullying perpetration were correlates of the perpetration of cyber dating abuse. Collectively, the findings suggest that dating violence interventions targeting these particular correlates in early adolescents are warranted. Future studies are needed to establish causation and to further investigate the relative importance of correlates of the perpetration of cyber dating abuse among early adolescents that have been reported among older adolescents.

RESUMO

BACKGROUND: American Indian and Alaska Native (AI/AN) youth face multiple health challenges compared to other racial/ethnic groups, which could potentially be ameliorated by the dissemination of evidence-based adolescent health promotion programs. Previous studies have indicated that limited trained personnel, cultural barriers, and geographic isolation may hinder the reach and implementation of evidence-based health promotion programs among AI/AN youth. Although Internet access is variable in AI/AN communities across the United States, it is swiftly and steadily improving, and it may provide a viable strategy to disseminate evidence-based health promotion programs to this underserved population. OBJECTIVE: We explored the potential of using the Internet to disseminate evidence-based health promotion programs on multiple health topics to AI/AN youth living in diverse communities across 3 geographically dispersed regions of the United States. Specifically, we assessed the Internet's potential to increase the reach and implementation of evidence-based health promotion programs for AI/AN youth, and to engage AI/AN youth. METHODS: This randomized controlled trial was conducted in 25 participating sites in Alaska, Arizona, and the Pacific Northwest. Predominantly AI/AN youth, aged 12-14 years, accessed 6 evidence-based health promotion programs delivered via the Internet, which focused on sexual health, hearing loss, alcohol use, tobacco use, drug use, and nutrition and physical activity. Adult site coordinators completed computer-based education inventory surveys, connectivity and bandwidth testing to assess parameters related to program reach (computer access, connectivity, and bandwidth), and implementation logs to assess barriers to implementation (program errors and delivery issues). We assessed youths' perceptions of program engagement via ratings on ease of use, understandability, credibility, likeability, perceived impact, and motivational appeal, using previously established measures. RESULTS: Sites had sufficient computer access and Internet connectivity to implement the 6 programs with adequate fidelity; however, variable bandwidth (ranging from 0.24 to 93.5 megabits per second; mean 25.6) and technical issues led some sites to access programs via back-up modalities (eg, uploading the programs from a Universal Serial Bus drive). The number of youth providing engagement ratings varied by program (n=40-191; 48-60% female, 85-90% self-identified AI/AN). Across programs, youth rated the programs as easy to use (68-91%), trustworthy (61-89%), likeable (59-87%), and impactful (63-91%). Most youth understood the words in the programs (60-83%), although some needed hints to complete the programs (16-49%). Overall, 37-66% of the participants would recommend the programs to a classmate, and 62-87% found the programs enjoyable when compared to other school lessons. CONCLUSIONS: Findings demonstrate the potential of the Internet to enhance the reach and implementation of evidence-based health promotion programs, and to engage AI/AN youth. Provision of back-up modalities is recommended to address possible connectivity or technical issues. The dissemination of Internet-based health promotion programs may be a promising strategy to address health disparities for this underserved population.

RESUMO

PURPOSE: American Indian and Alaska Native (AI/AN) youth experience disparities associated with sexual and reproductive health, including early age of sexual initiation. Identifying factors that are most proximally related to early sexual intercourse and that are modifiable through health promotion interventions may help to reduce these disparities. Using a multisystem approach, we assessed individual (biological, psychological, and behavioral), familial, and extrafamilial (peer behavioral) factors associated with lifetime sexual experience among AI/AN early adolescents living in three geographically dispersed U.S. regions. METHODS: We analyzed cross-sectional data from 537 AI/AN youth aged 12-14 years, recruited from 27 study sites in Alaska, Arizona, and the Pacific Northwest. We used multilevel logistic regression models to estimate associations between independent variables and lifetime sexual intercourse (oral and/or vaginal sex) individually, within discrete systems, and across systems. RESULTS: The analytical sample was 55.1% female, with a mean age of 13.2 years (standard deviation = 1.06 years); 6.5% were sexually experienced. In the final model, we found that lower next-year intentions to have oral or vaginal sex (psychological factors), avoidance of risky situations, and nonuse of alcohol (behavioral factors) were associated with lower odds of lifetime sexual intercourse (all p ≤ .01). No other variables were significantly associated with lifetime sexual intercourse. CONCLUSIONS: Interventions that reduce sexual intentions, exposure to risky situations, and alcohol use may help to delay sexual initiation among AI/AN early adolescents.

RESUMO

PURPOSE: Few computer-based HIV, sexually transmitted infection (STI), and pregnancy prevention programs are available, and even fewer target early adolescents. In this study, we tested the efficacy of It's Your Game (IYG)-Tech, a completely computer-based, middle school sexual health education program. The primary hypothesis was that students who received IYG-Tech would significantly delay sexual initiation by ninth grade. METHODS: We evaluated IYG-Tech using a randomized, two-arm nested design among 19 schools in a large, urban school district in southeast Texas (20 schools were originally randomized). The target population was English-speaking eighth-grade students who were followed into the ninth grade. The final analytic sample included 1,374 students. Multilevel logistic regression models were used to test for differences in sexual initiation between intervention and control students, while adjusting for age, gender, ethnicity, time between measures, and family structure. RESULTS: There was no significant difference in the delay of sexual activity or in any other sexual behavior between intervention and control students. However, there were significant positive between-group differences for psychosocial variables related to STI and condom knowledge, attitudes about abstinence, condom use self-efficacy, and perceived norms about sex. Post hoc analyses conducted among intervention students revealed some significant associations: "full exposure" (completion of all 13 lessons) and "mid-exposure" (5-8 lessons) students were less likely than "low exposure" (1-4 lessons) students to initiate sex. CONCLUSIONS: Collectively, our findings indicate that IYG-Tech impacts some determinants of sexual behavior, and that additional efficacy evaluation with full intervention exposure may be warranted.

RESUMO

OBJECTIVES: We examined whether It's Your Game . . . Keep It Real (IYG) reduced dating violence among ethnic-minority middle school youths, a population at high risk for dating violence. METHODS: We analyzed data from 766 predominantly ethnic-minority students from 10 middle schools in southeast Texas in 2004 for a group randomized trial of IYG. We estimated logistic regression models, and the primary outcome was emotional and physical dating violence perpetration and victimization by ninth grade. RESULTS: Control students had significantly higher odds of physical dating violence victimization (adjusted odds ratio [AOR] = 1.52; 95% confidence interval [CI] = 1.20, 1.92), emotional dating violence victimization (AOR = 1.74; 95% CI = 1.36, 2.24), and emotional dating violence perpetration (AOR = 1.58; 95% CI = 1.11, 2.26) than did intervention students. The odds of physical dating violence perpetration were not significantly different between the 2 groups. Program effects varied by gender and race/ethnicity. CONCLUSIONS: IYG significantly reduced 3 of 4 dating violence outcomes among ethnic-minority middle school youths. Although further study is warranted to determine if IYG should be widely disseminated to prevent dating violence, it is one of only a handful of school-based programs that are effective in reducing adolescent dating violence behavior.

RESUMO

PURPOSE: An earlier randomized controlled trial found that two middle school sexual education programs-a risk avoidance (RA) program and a risk reduction (RR) program-delayed initiation of sexual intercourse (oral, vaginal, or anal sex) and reduced other sexual risk behaviors in ninth grade. We examined whether these effects extended into 10th grade. METHODS: Fifteen middle schools were randomly assigned to RA, RR, or control conditions. Follow-up surveys were conducted with participating students in 10th grade (n = 1,187; 29.2% attrition). RESULTS: Participants were 60% female, 50% Hispanic, and 39% black; seventh grade mean age was 12.6 years. In 10th grade, compared with the control condition, both programs significantly delayed anal sex initiation in the total sample (RA: adjusted odds ratio [AOR], .64, 95% confidence interval [CI], .42-.99; RR: AOR, .65, 95% CI, .50-.84) and among Hispanics (RA: AOR, .53, 95% CI, .31-.91; RR: AOR, .82, 95% CI, .74-.93). Risk avoidance students were less likely to report unprotected vaginal sex, either by using a condom or by abstaining from sex (AOR: .61, 95% CI, .45-.85); RR students were less likely to report recent unprotected anal sex (AOR: .34, 95% CI, .20-.56). Both programs sustained positive impact on some psychosocial outcomes. CONCLUSIONS: Although both programs delayed anal sex initiation into 10th grade, effects on the delayed initiation of oral and vaginal sex were not sustained. Additional high school sexual education may help to further delay sexual initiation and reduce other sexual risk behaviors in later high school years.

RESUMO

Adolescent sexually transmitted infection (STI) and birth rates indicate a need for effective middle school HIV/STI, and pregnancy prevention curricula to delay, or mitigate consequences of, early sexual activity. Individual and organizational barriers to adoption, implementation, and maintenance, however, can hamper dissemination of evidence-based sexual health curricula, adversely impacting fidelity and reach. Internet-based approaches may help mitigate these barriers. This paper describes the development and feasibility testing of It's Your Game (IYG)-Tech, a stand-alone 13-lesson Internet-based sexual health life-skills curriculum adapted from an existing effective sexual health curriculum-It's Your Game… Keep it Real (IYG). IYG-Tech development adaptation steps were to: 1) Select a suitable effective program and gather the original program materials; 2) Develop "proof of concept" lessons and test usability and impact; 3) Develop the program design document describing the core content, scope, and methods and strategies; and 4) produce the new program. Lab- and school-based tests with middle school students demonstrated high ratings on usability parameters and immediate impact on selected psychosocial factors related to sexual behavior-perceptions of friends' beliefs, reasons for not having sex, condom use self-efficacy, abstinence intentions, negotiating with others to protect personal rules, and improved knowledge about what constitutes healthy relationships (all p < .05). Youth rated IYG-Tech is favorably compared to other learning channels (>76.2% agreement) and rated the lessons as helpful in making healthy choices, selecting personal rules, detecting challenges to those rules, and protecting personal rules through negotiation and refusal skills (89.5% - 100%). Further efficacy testing is indicated for IYG-Tech as a potential strategy to deliver effective HIV/STI, and pregnancy prevention to middle school youth.

RESUMO

BACKGROUND: Whereas dating violence among high school students has been linked with sexual risk-taking and substance use, this association has been understudied among early adolescents. We estimated the prevalence of physical and nonphysical dating violence in a sample of middle school students and examined associations between dating violence, sexual, and substance use behaviors. METHODS: Logistic regression models for clustered data from 7th grade students attending 10 Texas urban middle schools were used to examine cross-sectional associations between dating violence victimization and risk behaviors. RESULTS: The sample (N = 950) was 48.5% African American, 36.0% Hispanic, 55.7% female, mean age 13.1 years (SD 0.64). About 1 in 5 reported physical dating violence victimization, 48.1% reported nonphysical victimization, and 52.6% reported any victimization. Adjusted logistic regression analyses indicated that physical, nonphysical, and any victimization was associated with ever having sex, ever using alcohol, and ever using drugs. CONCLUSIONS: Over 50% of sampled middle school students had experienced dating violence, which may be associated with early sexual initiation and substance use. Middle school interventions that prevent dating violence are needed.

RESUMO

Although sexting among U.S. youth has received much popular media attention, there are only limited data on its prevalence among ethnic minority youth. This study, therefore, specifically examined the prevalence and patterns of sexting (sending and/or receiving a nude or semi-nude picture/video or a sexual text-only message) among a sample of black and Hispanic youth. Data from 1,034 tenth graders from a large, urban school district in southeast Texas were used to calculate the prevalence of sexting by gender-race/ethnicity. Overlap among sexting behaviors was also examined. Electronic surveys were administered via an audio-computer-assisted self-interview on laptop computers. Prevalence estimates were obtained, and chi-square analyses were conducted to compare the distribution of sexting behaviors by gender-race/ethnicity subgroups. More than 20% of students reported sending either a nude or semi-nude picture/video or a sexual text-only message (jointly referred to as a "sext"), and more than 30% reported receiving a sext. Sexts were also frequently shared with unintended recipients. Black males and females reported similar prevalence estimates for sexting behaviors. However, they were more likely than Hispanic males to participate in some sexting behaviors. Hispanic females reported the lowest estimates for sexting behaviors for all gender-race/ethnicity subgroups. Many youth who sent or received a nude or semi-nude picture/video were also likely to have sent or received sexual text-only messages. The results of this study indicate that sexting is prevalent among ethnic minority youth. However, more research is needed to understand the specific context and circumstances around which sexting occurs in this population.

RESUMO

PURPOSE: To evaluate the efficacy of two, theory-based, multimedia, middle school sexual education programs in delaying sexual initiation. METHODS: Three-armed, randomized controlled trial comprising 15 urban middle schools; 1,258 predominantly African American and Hispanic seventh grade students followed into ninth grade. Both programs included group and individualized, computer-based activities addressing psychosocial variables. The risk avoidance (RA) program met federal abstinence education guidelines; the risk reduction (RR) program emphasized abstinence and included computer-based condom skills-training. The primary outcome assessed program impact on delayed sexual initiation; secondary outcomes assessed other sexual behaviors and psychosocial outcomes. RESULTS: Participants were 59.8% females (mean age: 12.6 years). Relative to controls, the RR program delayed any type of sexual initiation (oral, vaginal, or anal sex) in the overall sample (adjusted odds ratio [AOR]: .65, 95% CI: .54-.77), among females (AOR: .43, 95% CI: .31-.60), and among African Americans (AOR: .38, 95% CI: .18-.79). RR students also reduced unprotected sex at last intercourse (AOR: .67, 95% CI: .47-.96), frequency of anal sex in the past 3 months (AOR: .53, 95% CI: .33-.84), and unprotected vaginal sex (AOR: .59, 95% CI: .36-.95). The RA program delayed any sexual initiation among Hispanics (AOR: .40, 95% CI: .19-.86), reduced unprotected sex at last intercourse (AOR: .70, 95% CI: .52-.93), but increased the number of recent vaginal sex partners (AOR: 1.69, 95% CI: 1.01-2.82). Both programs positively affected psychosocial outcomes. CONCLUSIONS: The RR program positively affected sexually inexperienced and experienced youth, whereas the RA program delayed initiation among Hispanics and had mixed effects among sexually experienced youth.

RESUMO

PURPOSE: This study tested the effects of a theory-based, middle-school human immunodeficiency virus, STI, and pregnancy prevention program, It's Your Game: Keep it Real (IYG), in delaying sexual behavior. We hypothesized that the IYG intervention would decrease the number of adolescents who initiated sexual activity by the ninth grade compared with those in the comparison schools. METHODS: The target population consisted of English-speaking middle school students from a large, urban, predominantly African-American and Hispanic school district in Southeast Texas. Ten middle schools were randomly assigned either to receive the intervention or to the comparison condition. Seventh-grade students were recruited and followed through ninth grade. The IYG intervention comprises 12 seventh-grade and 12 eighth-grade lessons that integrate group-based classroom activities with computer-based instruction and personal journaling. Ninth-grade follow-up surveys were completed by 907 students (92% of the defined cohort). The primary hypothesis tested was that the intervention would decrease the number of adolescents who initiated sexual activity by the ninth grade compared with those in the comparison schools. RESULTS: Almost one-third (29.9%, n=509) of the students in the comparison condition initiated sex by ninth grade compared with almost one-quarter (23.4%, n=308) of those in the intervention condition. After adjusting for covariates, students in the comparison condition were 1.29 times more likely to initiate sex by the ninth grade than those in the intervention condition. CONCLUSIONS: A theory-driven, multi-component, curriculum-based intervention can delay sexual initiation up to 24 months; can have impact on specific types of sexual behavior such as initiation of oral and anal sex; and may be especially effective with females. Future research must explore the generalizabilty of these results.

RESUMO

Media consumption may contribute to childhood obesity. This study developed and evaluated a theory-based, parent-focused intervention to reduce television and other media consumption to prevent and reduce childhood obesity. Families (n = 202) with children ages 6-9 were recruited from a large, urban multiethnic population into a randomized controlled trial (101 families into the intervention group and 101 into the control group), and were followed for 6 months. The intervention consisted of a 2-hour workshop and six bimonthly newsletters. Behavioral objectives included: (i) reduce TV watching; (ii) turn off TV when nobody is watching; (iii) no TV with meals; (iv) no TV in the child's bedroom; and (v) engage in fun non-media related activities. Parents were 89% female, 44% white, 28% African American, 17% Latino, and 11% Asian, mean age 40 years (s.d. = 7.5); 72% were married. Children were 49% female, mean age 8 years (s.d. = 0.95). Sixty-five percent of households had three or more TVs and video game players; 37% had at least one handheld video game, and 53% had three or more computers. Average children's weekday media exposure was 6.1 hours. At 6 months follow-up, the intervention group was less likely to report the TV being on when nobody was watching (adjusted odds ratio (AOR) = 0.23, P < 0.05), less likely to report eating snacks while watching TV (AOR = 0.47, P < 0.05), and less likely to have a TV in the child's bedroom (AOR = 0.23, P < 0.01). There was a trend toward reducing actual media consumption but these outcomes did not reach statistical significance. Effective strategies to reduce children's TV viewing were identified.

RESUMO

BACKGROUND: This study examines the prevalence of vaginal, oral, and anal intercourse among a population of urban, public middle school students, the characteristics of early sexual initiators, and the sequence of sexual initiation. Such data are limited for early adolescents. METHODS: A total of 1279 seventh-grade students (57.3% female, 43.6% black, and 41.8% Hispanic), mean age 12.5 years (SD = 0.63) from 10 middle schools in a large southeastern US public school district completed a cross-sectional survey using audio computer-assisted self-interviews. Main outcomes included lifetime and past 3-months' experience of vaginal, oral, and anal sex; condom use; age of initiation; and number of lifetime partners. RESULTS: Overall, 12.0% of students had engaged in vaginal sex, 7.9% in oral sex, and 6.5% in anal sex. Among students who had initiated intercourse, approximately two thirds were currently sexually active and one quarter reported > or =4 lifetime partners. Six percent had engaged in 1 type of intercourse, 4% in 2 types of intercourse, and 4% in all 3 types of intercourse; vaginal sex was typically initiated at an earlier or at the same age as other types of intercourse. Only 2% had engaged in oral sex without engaging in vaginal sex. Although black students were significantly more likely to have initiated sex compared to other racial/ethnic groups, Hispanic students who had initiated each type of intercourse were more likely to be currently sexually active and to have engaged in recent unprotected sex. CONCLUSIONS: A small percentage of early adolescents are engaging in multiple sexual behaviors. These findings have implications for early adolescent school-based sexual health education.
