Intimate partner violence in late adolescence and young adulthood and subsequent cardiovascular risk in adulthood.

BACKGROUND: Childhood maltreatment has been linked to adulthood cardiovascular disease (CVD). Little is known about the relationship between intimate partner violence (IPV) in late adolescence and young adulthood and CVD risk later in adulthood. PURPOSE: To examine whether IPV perpetration and victimization experienced in late adolescence and young adulthood are associated with CVD risk among adults in the United States and whether this relationship differs by sex. METHODS: Data include 9976 participants (50% female) in the National Longitudinal Study of Adolescent to Adult Health. Physical and sexual IPV were measured at wave 3 (2001/02) with items from the revised Conflict Tactics Scales. Participants'30-year risk of CVD was calculated at wave 4 (2008/09) using a Framingham prediction model. Linear regression models adjusted for confounders and IPV by sex interaction terms were tested to examine the relationship. RESULTS: The mean CVD risk score was 13.18% (95% CI: 12.71, 13.64). Aone-standard deviation increase in the victimization score was associated with a 0.28% (95% CI: 0.03, 0.54) increase in CVD risk. Perpetration was similarly positively associated with CVD risk (beta: 0.33, 95% CI: 0.03, 0.62). When measured as a composite, all violence types were associated with increased CVD risk but only prior exposure to both victimization and perpetration reached statistical significance (0.62%, 95% CI: 0.01, 1.22). No differences by sex were detected. CONCLUSIONS: Effect sizes are not large, but early detection of increased CVD risk in this relatively young population is notable and worthy of further study to inform the clinical response.

Adolescence as a critical stage in the MCH Life Course Model: commentary for the Leadership Education in Adolescent Health (LEAH) interdisciplinary training program projects.

The Life Course Perspective (LCP), or Model, is now a guiding framework in Maternal and Child Health (MCH) activities, including training, supported by the Health Resources and Services Administration's Maternal and Child Health Bureau. As generally applied, the LCP tends to focus on pre- through post-natal stages, infancy and early childhood, with less attention paid to adolescents as either the "maternal" or "child" elements of MCH discourse. Adolescence is a distinct developmental period with unique opportunities for the development of health, competence and capacity and not merely a transitional phase between childhood and adulthood. Adequately addressing adolescents' emergent and ongoing health needs requires well-trained and specialized professionals who recognize the unique role of this developmental period in the LCP.

A clinic-based youth development program to reduce sexual risk behaviors among adolescent girls: prime time pilot study.

Multifaceted, sustained efforts are needed to reduce early pregnancy and sexually transmitted diseases among high-risk adolescents. An important area for research is testing youth development interventions offered through clinic settings, where access to high-risk adolescents is plentiful and few efforts have rigorously evaluated a dual approach of building protective factors while addressing risk. This article presents findings from a pilot study of Prime Time, a clinic-based youth development intervention to reduce sexual risk behaviors among girls at risk for early pregnancy. Girls aged 13 to 17 years meeting specified risk criteria were assigned to Prime Time treatment groups. The Prime Time intervention included a combination of case management services and peer leadership groups. Participants completed self-report surveys at baseline, 12 and 18 months following enrollment. At 12 months, the intervention group reported significantly fewer sexual partners than the control group. At 18 months, the intervention group reported significantly more consistent condom use with trends toward more consistent hormonal and dual method use. Dose-response analyses suggested that relatively high levels of exposure to a youth development intervention were needed to change contraceptive use behaviors among adolescents at risk for early pregnancy. Given promising findings, further testing of the Prime Time intervention is warranted.

Protective factors in the lives of bisexual adolescents in North America.

OBJECTIVES: We compared protective factors among bisexual adolescents with those of heterosexual, mostly heterosexual, and gay or lesbian adolescents. METHODS: We analyzed 6 school-based surveys in Minnesota and British Columbia. Sexual orientation was measured by gender of sexual partners, attraction, or self-labeling. Protective factors included family connectedness, school connectedness, and religious involvement. General linear models, conducted separately by gender and adjusted for age, tested differences between orientation groups. RESULTS: Bisexual adolescents reported significantly less family and school connectedness than did heterosexual and mostly heterosexual adolescents and higher or similar levels of religious involvement. In surveys that measured orientation by self-labeling or attraction, levels of protective factors were generally higher among bisexual than among gay and lesbian respondents. Adolescents with sexual partners of both genders reported levels of protective factors lower than or similar to those of adolescents with same-gender partners. CONCLUSIONS: Bisexual adolescents had lower levels of most protective factors than did heterosexual adolescents, which may help explain their higher prevalence of risky behavior. Social connectedness should be monitored by including questions about protective factors in youth health surveys.

Res ipsa loquitur: "the thing speaks for itself": so why isn't evidence enough for enactment?

The gap between scientific evidence and its application poses profound challenges to adolescent healthcare researchers, educators, and advocates. These challenges are compounded by the alliance of political power with social and religious ideology, the consequence of which is the distortion and undermining of scientific evidence and inquiry. This article, based on a keynote presentation to the Center for Health Promotion Research Conference on Adolescent Health, describes examples of such interference and the need for effective response to those who deliberately seek to widen the gap between evidence-based approaches to adolescent health, as well as the implementation of such knowledge in programs and policy.

Protecting urban American Indian young people from suicide.

OBJECTIVE: To examine the likelihood of a past suicide attempt for urban American Indian boys and girls, given salient risk and protective factors. METHODS: Survey data from 569 urban American Indian, ages 9-15, in-school youths. Logistic regression determined probabilities of past suicide attempts. RESULTS: For girls, suicidal histories were associated with substance use (risk) and positive mood (protective); probabilities ranged from 6.0% to 57.0%. For boys, probabilities for models with violence perpetration (risk), parent prosocial behavior norms (protective), and positive mood (protective) ranged from 1.0% to 38.0%. CONCLUSIONS: Highlights the value of assessing both risk and protective factors for suicidal vulnerability and prioritizing prevention strategies.

Protective factors and suicide risk in adolescents with a history of sexual abuse.

OBJECTIVE: To test the hypothesis that certain protective factors will reduce the risk of suicide behaviors in youth who are sexually abused. STUDY DESIGN: Survey data come from 83,731 students in the 6th, 9th, and 12th grades in Minnesota. Four childhood sexual abuse groups were created: a) no history of sexual abuse; b) abuse by non-family member; c) abuse by family member; and d) abuse by both. Dependent variables included suicidal ideation and attempts. Four protective factors included: family connectedness, teacher caring, other adult caring, and school safety. Logistic regression was used in detecting differences in suicide behaviors across the 4 childhood sexual abuse categories. RESULTS: Four percent of students reported sexual abuse by a non-family member, 1.3% by a family member, and 1.4% by both. Although youth with a history of childhood sexual abuse were at increased risk for suicide behaviors compared with other youth, when protective factors were accounted for, the predicted probabilities of suicide behaviors for childhood sexual abuse youth were substantially reduced. Family connectedness was the strongest of the 4 protective factors. CONCLUSION: Modifying select protective factors, particularly family connectedness, may reduce suicide risk in adolescents with childhood sexual abuse.

Youth-Adult Connectedness:: A Key Protective Factor for Adolescent Health.

Over the past 30 years, prevention science in the adolescent health field has moved from interventions focused on preventing single problem behaviors to efforts employing a dual approach, addressing risk factors that predict problems while simultaneously nurturing protective factors and promoting positive development. Through an examination of previous research and empirical case examples with vulnerable youth, this article considers the hypothesis that adolescents' sense of connectedness to caring adults acts as a protective factor against a range of risk behaviors. Multivariate analyses with existing data examined indicators of youth-adult connectedness among two groups at high risk for poor health outcomes: (1) mentor-youth relationship quality in an urban, ethnically diverse sample of students in a school-based mentoring program (2014 survey, N=239); and (2) parent-youth connectedness in a statewide sample of high school students who reported homelessness in the past year (2013 survey, N=3,627). For youth in the mentoring program, a high-quality youth-mentor relationship was significantly associated with positive social, academic, and health-related behaviors. Among students who experienced homelessness, all measures of parent connectedness were significantly associated with lower sexual risk levels. Collectively, findings from these analyses and previously published studies by this research group provide evidence that strong, positive relationships with parents and other caring adults protect adolescents from a range of poor health-related outcomes and promote positive development. Youth-adult connectedness appears to be foundational for adolescent health and well-being. Program, practice, and policy decisions should consider what strengthens or hinders caring, connected youth-adult relationships.

Parental notification laws for minors' access to contraception: what do parents say?

BACKGROUND: Recent years have seen new challenges to laws protecting minors' confidential access to reproductive health services. Little research has explored parental views on the issue. OBJECTIVE: To examine parents' views about laws requiring parental notification (PNLs) when minor children seek to obtain prescription contraceptives, the exceptions parents would endorse, and the consequences they would expect. DESIGN: Fifteen-minute telephone surveys conducted in 2002. SETTING: Minnesota and Wisconsin. PARTICIPANTS: Population-based sample of 1069 parents of adolescents aged 13 to 17 years with a working telephone number. An additional 1095 eligible parents declined and 360 were not available to participate. MAIN OUTCOME MEASURES: Views about PNLs ("Do you think a law requiring notification of parents when a teen requests birth control from a clinic is a good idea, a bad idea, or neither a good nor a bad idea?"). RESULTS: Of the eligible parents, 42.4% completed the survey. More than half (55.1%) of participants thought PNLs were a good idea. However, 96.1% of parents expected at least 1 negative consequence and 47.6% expected 5 or more negative consequences to result with the enactment of PNLs. For exceptions to PNLs, 85.5% of parents endorsed at least 1, and 29.7% endorsed 5 to 6. Each additional anticipated positive consequence of enacting PNLs was significantly associated with more than twice the odds of favoring PNLs (odds ratio [OR], 2.28), and each additional negative consequence was associated with lower odds of supporting PNLs (OR, 0.87). Likewise, each additional exception endorsed was associated with lower odds of supporting PNLs (OR, 0.71). CONCLUSIONS: Many parents hold complex views on the need for confidentiality and the appropriate involvement of parents in adolescent health care services. Educating parents about the potential negative consequences of parental notification could change their support of PNLs.

Violence perpetration among urban american Indian youth: can protection offset risk?

OBJECTIVE: To predict the likelihood of violence perpetration given various combinations of the most statistically salient risk and protective factors related to violence perpetration. DESIGN: Urban Indian Youth Health Survey, conducted from October 9, 1995, to March 30, 1998, consisting of 200 forced-choice items exploring values, cultural identity, relationships, decision-making skills, and health and well-being. SETTING: Urban schools and an after-school youth development program at an urban American Indian center. PARTICIPANTS: Five hundred sixty-nine urban American Indian youth enrolled in grades 3 through 12. MAIN OUTCOME MEASURES: Violence perpetration dichotomized in 2 ways: (1) level of violence perpetration (ie, hitting someone 1-2 times in the past year vs picking fights, hitting repeatedly, participating in group fights, or shooting or stabbing someone in the past year) and (2) having shot and/or stabbed someone during the past year. RESULTS: In the final multivariate models with age as a covariate, most protective against violence perpetration were connections to school (odds ratio [OR], 0.17), positive affect (OR, 0.29), and peer prosocial behavior norms against violence (OR, 0.35). School connectedness (OR, 0.01) and positive affect (OR, 0.46) were also protective against shooting and/or stabbing someone, as was parental prosocial behavior norms against violence (OR, 0.23). The strongest risk factors for violence perpetration were substance use (OR, 2.60) and suicidal thoughts/behaviors (OR, 2.71); for shooting and/or stabbing, it was substance use (OR, 5.26). The likelihood of violence perpetration increased markedly (from 10% to 85%) as the exposure to risk factors increased and protective factors decreased. For shooting or stabbing someone, the probabilities ranged from 3% (0 risks and 3 protective factors) to 64% (1 risk and 0 protective factors). CONCLUSION: The dramatic reduction in the likelihood of violence involvement when risk was offset with protective factors in the probability profiles suggests the utility of a dual strategy of reducing risk while boosting protection.

Predicting adolescents' longitudinal risk for sexually transmitted infection: results from the National Longitudinal Study of Adolescent Health.

BACKGROUND: Influencing adolescents' sexual behaviors has the potential to influence trajectories of risk for sexually transmitted infections (STIs) among young adults. OBJECTIVE: To determine whether family, school, and individual factors associated with increased duration of virginity also protect against STIs in young adulthood. DESIGN: Prospective cohort study. Wave I of the National Longitudinal Study of Adolescent Health occurred in 1995 when participants were in grades 7 through 12. Six years later, all wave I participants who could be located were invited to participate in wave III and provide a urine specimen for STI testing. SETTING: In-home interviews in the continental United States, Alaska, and Hawaii. PARTICIPANTS: Population-based sample. Of 18,924 participants in the nationally representative weighted wave I sample, 14,322 (75.7%) were located and participated in wave III. Test results for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis were available for 11,594 (81.0%) of wave III participants. MAIN OUTCOME MEASURE: Positive test result for C. trachomatis, N. gonorrhoeae, or T. vaginalis. RESULTS: Controlling for biological sex, age, race/ethnicity, family structure, and maternal education, adolescents who perceived that their parents more strongly disapproved of their having sex during adolescence were less likely to have STIs 6 years later (adjusted odds ratio, 0.89; 95% confidence interval, 0.81-0.99). Those with a higher grade point average during adolescence were also less likely to acquire STIs (adjusted odds ratio, 0.84; 95% confidence interval, 0.71-0.99). Stratified analyses confirmed these findings among female, but not male, adolescents. Feelings of connection to family or school, reported importance of religion, attending a parochial school, and pledges of virginity during adolescence did not predict STI status 6 years later. CONCLUSIONS: Perceived parental disapproval of sexual intercourse and higher grades in school during adolescence have protective influences on the trajectory of risk for acquiring STIs, primarily among female adolescents. Most factors associated with increased duration of virginity in adolescence do not influence the trajectory of STI risk.

Parents' beliefs about condoms and oral contraceptives: are they medically accurate?

CONTEXT: Parents are encouraged to be the primary sex educators for their children; however, little is known about the accuracy of parents' views about condoms and oral contraceptives. METHODS: Telephone surveys using validated measures provided data on beliefs about the effectiveness, safety and usability of condoms and the pill among 1,069 parents of 13-17-year-olds in Minnesota and Wisconsin in 2002. Pearson chi-square tests and multivariate logistic regression models were used to compare beliefs according to sex, age, race, religion, education, income and political orientation. RESULTS: Substantial proportions of parents underestimated the effectiveness of condoms for preventing pregnancy and sexually transmitted diseases (STDs). Only 47% believed that condoms are very effective for STD prevention, and 40% for pregnancy prevention. Fifty-two percent thought that pill use prevents pregnancy almost all the time; 39% thought that the pill is very safe. Approximately one-quarter of parents thought that most teenagers are capable of using condoms correctly; almost four in 10 thought that most teenagers can use the pill correctly. Fathers tended to have more accurate views about condoms than mothers did; mothers' views of the pill were generally more accurate than fathers'. Whites were more likely than nonwhites to hold accurate beliefs about the pill's safety and effectiveness; conservatives were less likely than liberals to hold accurate views about the effectiveness of condoms. CONCLUSION: Campaigns encouraging parents to talk with their teenagers about sexuality should provide parents with medically accurate information on the effectiveness, safety and usability of condoms and the pill.

Primary and secondary sexual abstinence in high school students.

PURPOSE: To assess reasons for choosing not to have sexual intercourse among two groups: virgins (primary abstainers) and already sexually experienced youth (secondary abstainers). METHODS: 73,464 Minnesota ninth- and twelfth-grade adolescents completed the 1998 Minnesota Student Survey. Respondents identified reasons for abstinence from a checklist from which they could nominate all relevant items. Reasons for each group were analyzed using Chi-square with a conservative criterion value (p <.001) owing to large sample size. Logistic regression was used to examine the associations of gender, grade, and their interactions, with reasons for abstinence. RESULTS: Sixty-six percent reported never having had intercourse (primary abstainers). Among sexually experienced youth, 7.8% reported choosing not to have intercourse (secondary abstainers). Fear of pregnancy was the reason endorsed most often, more by girls than by boys (OR = 26 for primary abstainers, 6.9 for secondary abstainers). Fear of other adverse consequences, such as sexually transmitted infections, parental disapproval, or fear of getting caught, were generally selected by more girls than boys, and by more primary than secondary abstainers. Similarly, more girls and primary abstainers than boys or secondary abstainers generally selected statements reflecting normative beliefs on youth or their friends having intercourse. CONCLUSIONS: Fear of adverse consequences and normative beliefs about the appropriateness of having sexual intercourse were most frequently endorsed as important reasons by both groups of abstainers.

Unhealthy behaviors and psychosocial difficulties among overweight adolescents: the potential impact of familial factors.

PURPOSE: To compare overweight and non-overweight youth on a selection of self-reported eating, physical activity, dieting, educational, and emotional variables and identify familial factors that serve as protective forces against unhealthy behaviors and psychosocial difficulties among overweight adolescents. METHODS: Data were taken from a 1996 cross-sectional school-based survey of 9957 adolescents in grades 7, 9, and 11. Based on self-reported heights and weights, respondents were categorized as "overweight" (body mass index) > or =85th percentile or "non-overweight." Student's t-tests were used to compare the non-overweight and overweight sample on the self-reported health-related behaviors and psychosocial variables. Logistic and linear regressions were used to identify familial factors associated with a reduced risk of engaging in unhealthy behaviors and experiencing psychosocial distress. RESULTS: Overweight adolescents reported engaging in significantly more unhealthy behaviors and experiencing more psychosocial distress than their non-overweight peers. Among the overweight youth, higher levels of reported family connectedness and parental expectations and moderate levels of parental monitoring were associated with the lowest levels of unhealthy behaviors and psychosocial distress. CONCLUSIONS: Satisfying and developmentally appropriate parent-adolescent relationships are associated with reduced behavioral and psychosocial risk factors associated with overweight during adolescence.

Weight-related sports involvement in girls: who is at risk for disordered eating?

A 225-item questionnaire was completed by 5163 female 7th, 9th and 11th grade public school students in their classrooms to examine factors associated with eating disorders among girls involved in weight-related sports. Eating disorder symptoms were found in almost one third of girls involved in weight-related and non-weight-related sports. However, after controlling for grade, race, SES, and study design effect, girls in weight-related sports were 51% more likely to have eating disorder symptoms. Also, among girls in weight-related sports who had eating disorders, substance abuse, physical and sexual abuse history, depressive symptoms, suicide attempts, low family communication, and low parental caring were 98% to 377% more common.

Violence risk and protective factors among youth held back in school.

OBJECTIVE: To identify risk and protective factors for violence perpetration among youth with a history of grade retention. DESIGN: Longitudinal analysis of in-home interviews of 13,781 adolescents in grades 7 through 12 conducted in 1995 and 1996. METHODS AND MEASURES: Serious interpersonal violence perpetration at time 2 by time 1 independent variables including measures of community and school context, family context, and individual characteristics. RESULTS: The 20% of girls and 28% of boys who had repeated 1 or more grades were more likely than those who had not to be in the top quintile of violence perpetration at time 2 (P <.001). For both girls and boys with a history of grade repetition, predictive risk factors with an odds ratio of 3 or greater (P <.001) included time 1 violence perpetration, violence victimization, weapon carrying, school problems, and alcohol and marijuana use. Although a high grade point average was a significant protective factor against violence perpetration for both girls (odds ratio, 0.36; P <.05) and boys (odds ratio, 0.23; P <.001), performance on a validated measure of verbal knowledge was not associated with violence perpetration over the study period. School connectedness, parent-family connectedness, and emotional well-being were also significant universal protectors against violence perpetration. CONCLUSIONS: Youth who are held back in school are at heightened risk for violence perpetration. Violence-related behaviors and substance use considerably increase the likelihood of this outcome. The findings suggest that schools can participate in violence prevention by providing youth with a positive community and academic experience.

Sexually active students' willingness to use school-based health centers for reproductive health care services in North Carolina.

OBJECTIVE: School-based health centers (SBHCs) in North Carolina offer limited reproductive health care services. We investigate sexually active students' willingness to seek these services at SBHCs if available and predictors of willingness to seek services. METHODS: Cross-sectional survey of 949 sexually experienced students in 2 middle and 5 high schools in North Carolina in 1994. Bivariate and multivariate analyses tested the influence of sociodemographic characteristics, risk of pregnancy/sexually transmitted infections (STIs), and past health care utilization on willingness to use SBHCs for sexuality-related services. RESULTS: Participants were 52% female, 52% black, and median age at first coitus was 13.0 years. Many (49%) had sex at least once a month. Most (52%) reported inconsistent contraception use. One-fifth (18%) of females had been pregnant; 10% of males reported getting a partner pregnant. Seventy-five percent had used SBHCs. Most reported they would use SBHCs for information to protect against pregnancy and STIs (58%), pregnancy testing (51%), and birth control (48%) if available. Females were more likely than males to report they would use these services (adjusted odds ratio = 3.4, 95% confidence interval = 1.9-6.7), especially those receiving free lunch (adjusted odds ratio = 2.9, 95% confidence interval = 1.2-6.8]) and those with inconsistent use of contraception. We found no association between past health care and willingness to use SBHC services. CONCLUSIONS: Most sexually experienced students report they would use their SBHC for reproductive/STI services if they were available. Absence of these services in SBHCs represents a missed opportunity to provide health care to adolescents who are at substantial risk of pregnancy and STIs.
