Parent and Adolescent Views on Barriers to Adolescent Preventive Health Care Utilization.

OBJECTIVES: To determine adolescent and parent views of barriers to annual adolescent preventive care. STUDY DESIGN: A nationally recruited cross-sectional study of adolescents between ages 13 and 18 years, and parents of adolescents from different families, were recruited. The primary outcome was self-report of preventive care in the last 12 months. Demographic, family health discussions, physical/emotional health importance, and preventive care barriers were gathered from adolescents and parents. RESULTS: The majority of the sample (500 adolescents and 504 parents in different families) reported a primary care visit within 12 months (parents = 78.7%; adolescents = 66.9%). Adolescent participants identified more barriers than parents (parents = 0.69; adolescents = 1.42). Adolescent who reported having discussions with parents about health (aOR 1.57, 95% CI 1.26-1.98) and seeing a subspecialist provider (aOR 3.72, CI 1.21-11.47) were more likely to report preventive visits. Barriers for parents and adolescents include the belief that an appointment is only needed when a child is sick (parent aOR 0.21, CI 0.08-0.61; adolescent aOR 0.29, CI 0.17-0.51) and family cannot afford cost (parent aOR 0.34, CI 0.15-0.81; adolescent aOR 0.50, CI 0.26-0.97). Barriers for parents include the child sees a specialist (aOR 0.26, CI 0.08-0.88) and their child does not need a checkup (aOR 0.12, CI 0.05-0.34). Lastly, a barrier for adolescents was parents never schedule preventive visits (aOR 0.31, CI 0.17-0.58). CONCLUSIONS: The Affordable Care Act has the potential to limit preventive care barriers. The results of the current study find there are parental and adolescent issues regarding preventive services that should be addressed.

Perspectives of family medicine physicians on the importance of adolescent preventive care: a multivariate analysis.

BACKGROUND: The study objective was to identify commonalities amongst family medicine physicians who endorse annual adolescent visits. METHODS: A nationally weighted representative on-line survey was used to explore pediatrician (N = 204) and family medicine physicians (N = 221) beliefs and behaviors surrounding adolescent wellness. Our primary outcome was endorsement that adolescents should receive annual preventive care visits. RESULTS: Pediatricians were significantly more likely (p < .01) to endorse annual well visits. Among family medicine physicians, bivariate comparisons were conducted between those who endorsed an annual visit (N = 164) compared to those who did not (N = 57) with significant predictors combined into two multivariate logistic regression models. Model 1 controlled for: patient race, proportion of 13-17 year olds in provider's practice, discussion beliefs scale and discussion behaviors with parents scale. Model 2 controlled for the same first three variables as well as discussion behaviors with adolescents scale. Model 1 showed for each discussion beliefs scale topic selected, family medicine physicians had 1.14 increased odds of endorsing annual visits (p < .001) and had 1.11 greater odds of endorsing annual visits with each one-point increase in discussion behaviors with parents scale (p = .51). Model 2 showed for each discussion beliefs scale topic selected, family medicine physicians had 1.15 increased odds of also endorsing the importance of annual visits (p < .001). CONCLUSIONS: Family medicine physicians that endorse annual visits are significantly more likely to affirm they hold strong beliefs about topics that should be discussed during the annual exam. They also act on these beliefs by talking to parents of teens about these topics. This group appears to focus on quality of care in thought and deed.

Proactive parents are assets to the health and well-being of teens.

OBJECTIVES: To analyze parents who self-identified themselves as being proactive parents (PPs) compared with non-PPs who were queried about their teen's health to understand common adolescent health concerns, parenting practices/behaviors around health, and whether their adolescent had received a preventive care visit in the last year STUDY DESIGN: Secondary analyses of parents (n = 504) from a nationally representative online panel were surveyed to assess health beliefs/attitudes, perceived adolescent health concerns, frequency of health discussions, topics that pediatricians should discuss, and their teen's last annual visit. Demographics, parental beliefs, frequency of health conversations, and topics that physicians should discuss were compared. Logistic regression determined the likelihood of PPs compared with non-PPs reporting a teen annual health visit within the last year. RESULTS: Greater education and having a single-child household were slightly more common among PPs. PPs expressed greater concern about their teens getting good grades, getting sick, and their teen's future (P < .001). PPs indicated a greater severity of worry (P < .02) across all health topics and rated issues of sexual health, vaccines, and stress/mental health as very important for pediatricians to discuss (P < .01). Controlling for demographics, PPs were 3.4 (95% CI 2.06-5.56) times more likely to report an annual visit of their teen in the last year. CONCLUSION: PPs are an asset to the health promotion and the well-being of their teens. PPs were more likely to have their teen receive an annual visit, report more frequent discussions about health, and place a high value on physician discussions about health.

Adolescent relationship violence: help-seeking and help-giving behaviors among peers.

Young people tend to disclose relationship violence experiences to their peers, if they disclose at all, yet little is known about the nature and frequency of adolescent help-seeking and help-giving behaviors. Conducted within a sample of 1,312 young people from four New York City high schools, this is the first paper to ask adolescent help-givers about the various forms of help they provide and among the first to examine how ethnicity and nativity impact help-seeking behaviors. Relationship violence victims who had ever disclosed (61%) were more likely to choose their friends for informal support. Ethnicity was predictive of adolescent disclosure outlets, whereas gender and nativity were not. Latinos were significantly less likely than non-Latinos to ever disclose to only friends, as compared to disclosing to at least one adult. The likelihood of a young person giving help to their friend in a violent relationship is associated with gender, ethnicity, and nativity, with males being significantly less likely than females to give all forms of help to their friends (talking to their friends about the violence, suggesting options, and taking action). Foreign-born adolescents are less likely to talk or suggest options to friends in violent relationships. This study also found that Latinos were significantly more likely than non-Latinos to report taking action with or on behalf of a friend in a violent relationship. This research shows that adolescents often rely on each other to address relationship violence, underlining the importance of adolescents' receipt of training and education on how to support their friends, including when to seek help from more formal services. To further understand the valuable role played by adolescent peers of victims, future research should explore both which forms of help are perceived by the victim to be most helpful and which are associated with more positive outcomes.

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.

Predictors of physical intimate partner violence in the lives of young women: victimization, perpetration, and bidirectional violence.

BACKGROUND: Dating violence in young people is highly prevalent, and bidirectional violence characterizes most violent relationships. However, there is limited data on predictors of bidirectional violence in young relationships. PURPOSE: To examine the frequency of victimization, perpetration, and bidirectional physical violence in young women's relationships and compare individual and relationship characteristics across violence profiles. METHODS: Six hundred eighteen young women visiting an urban reproductive health care clinic completed an anonymous survey using the Conflict in Adolescent Dating Relationships Inventory to measure their experience of violence with a partner in the last year. RESULTS: Thirty-four percent of women reported at least one instance of physical violence (3% "victim only" 12% "perpetrator only," 19% "bidirectional"). The frequency of violence in the previous year within the bidirectional profile was significantly higher than both the victim-only and perpetrator-only profiles. In all adjusted models, younger age, childhood sexual abuse, witnessing parental intimate partner violence (IPV), and relationship length remained significant. Black race was predictive of both perpetration and bidirectional violence, but not victimization. Compared to nulliparous women or those with one previous pregnancy, those who had had two or more had twice the odds of both victimization and bidirectional, but no increase in odds of perpetration. CONCLUSIONS: Bidirectional violence was the most common profile and was associated with the highest frequency of violent behaviors. Contrary to expectation, only two variables differed significantly across the three violence profiles. However, as hypothesized, bidirectional relationships were characterized by longer length, lending moderate support for social learning theory as one explanation underlying the occurrence of bidirectional violence.

Text4Health: impact of text message reminder-recalls for pediatric and adolescent immunizations.

OBJECTIVES: We conducted 2 studies to determine the impact of text message immunization reminder-recalls in an urban, low-income population. METHODS: In 1 study, text message immunization reminders were sent to a random sample of parents (n = 195) whose children aged 11 to 18 years needed either or both meningococcal (MCV4) and tetanus-diphtheria-acellular pertussis (Tdap) immunizations. We compared receipt of MCV4 or Tdap at 4, 12, and 24 weeks with age- and gender-matched controls. In the other study, we compared attendance at a postshortage Haemophilus influenzae B (Hib) immunization recall session between parents who received text message and paper-mailed reminders (n = 87) and those who only received paper-mailed reminders (n = 87). RESULTS: Significantly more adolescents with intervention parents received either or both MCV4 and Tdap at weeks 4 (15.4% vs 4.2%; P < .001), 12 (26.7% vs 13.9%; P < .005), and 24 (36.4% vs 18.1%; P < .001). Significantly more parents who received both Hib reminders attended a recall session compared with parents who only received a mailed reminder (21.8% vs 9.2%; P < .05). After controlling for age, gender, race/ethnicity, insurance status, and language, text messaging was still significantly associated with both studies' outcomes. CONCLUSIONS: Text messaging for reminder-recalls improved immunization coverage in a low-income, urban population.

Human papillomavirus vaccine in adolescent women: a 2012 update.

PURPOSE OF REVIEW: Despite recommendations from the Advisory Committee on Immunization Practices (ACIP) for routine vaccination of adolescents with the human papillomavirus (HPV) vaccine, U.S. coverage among women remains less than 50%, with that of adolescent men below 2%. RECENT FINDINGS: Ongoing studies document the efficacy and safety of the HPV vaccine. Nevertheless, misconceptions and negative attitudes persist and serve as barriers to vaccine uptake. Additionally, other factors such as age, insurance status, poverty status, and racial or ethnic background have been associated with diminished vaccine uptake and poor completion rates. Internationally, HPV vaccination programs and school-based programs have achieved increased rates of uptake and series completion. HPV vaccination coverage may also be facilitated by improving communication between physicians, parents, and adolescents as well as by addressing common misconceptions about the vaccine. SUMMARY: This review highlights significant findings of recent literature on HPV vaccination of adolescent women with a special focus on uptake, series completion, communication, disparities in vaccine coverage, and other health outcomes associated with HPV vaccination.

Changes in Tdap and MCV4 vaccine coverage following enactment of a statewide requirement of Tdap vaccination for entry into sixth grade.

OBJECTIVES: We evaluated changes in tetanus toxoid, reduced diphtheria toxoid, acellular pertussis (Tdap), and tetravalen meningococcal (MCV4) vaccine coverage following enactment of a New York State mandate requiring Tdap before entering sixth grade. METHODS: Using data from a hospital-based immunization registry, we measured Tdap and MCV4 coverage among youths aged 11 to 14 years in New York City at 3 time points: premandate, mandate year 1, and mandate year 2. RESULTS: Among overlapping cohorts of 4316 (premandate), 4131 (mandate year 1), and 3639 (mandate year 2) youths, Tdap coverage increased steadily over time (29%, 58%, and 83%, respectively). Increases were observed among all ages. Across the same time points, MCV4 coverage also increased (10%, 30%, and 60%, respectively). Most adolescents did not receive MCV4 during the same visit they received Tdap. CONCLUSIONS: A Tdap school-entry mandate was associated with substantial increases in immunization coverage, even in age groups not directly affected by the mandate. At the postmandate time points, MCV4 coverage remained lower than Tdap coverage. Provider education should emphasize the importance of reviewing vaccine records and administering all recommended vaccines at every clinical encounter.

Text4Health: a qualitative evaluation of parental readiness for text message immunization reminders.

We conducted focus groups and individual interviews in a diverse population of parents to qualitatively explore preferences and readiness for text message immunization reminders. We used content analysis to review and independently code transcripts. Text message reminders were well-accepted by parents; many thought they would be more effective than standard phone or mail reminders. Parents preferred text message reminders to be brief and personalized. Most parents were able to retrieve sample text messages but many had difficulty with interactive texting.

Comparability of contraceptive prevalence etimates for women from the 2002 Behavioral Risk Factor Surveillance System.

OBJECTIVE: This article assesses the comparability of contraceptive use estimates for adult women obtained from the 2002 Behavioral Risk Factor Surveillance System (BRFSS), using the 2002 National Survey of Family Growth (NSFG) as a benchmark. The 2002 BRFSS uses data collection methods that are considerably different from the NSFG. METHOD: We compared demographic differences and national estimates of current contraceptive methods being used and reasons for nonuse. Variables were recoded in the BRFSS and NSFG systems to make the two samples comparable. RESULTS: Women in the NSFG and BRFSS were similar in age and race/ethnicity. Compared with the NSFG, the BRFSS sample was more educated and of higher income, less likely to be cohabiting, and more likely to be married. After adjusting for differences in the coding of hysterectomy, many BRFSS estimates for current contraceptive use were statistically similar to those from the NSFG. Small but statistically significant differences were found for vasectomy (7.7% and 6.3%), the pill (21.9% and 19.6%), rhythm (1.5% and 1.0%), the diaphragm (0.5% and 0.2%), and withdrawal (0.3% and 2.7%) for the BRFSS and NSFG, respectively. Major reasons for nonuse were similar: seeking pregnancy and currently pregnant. The percentage of women who were not currently sexually active was higher in the BRFSS (16.0%) compared with the NSFG (12.5%). CONCLUSIONS: The BRFSS is a useful source of population-based data on contraceptive use for reproductive health program planning; however, planners should be cognizant that lower-income women are not fully represented in telephone surveys.

Dating violence, sexual assault, and suicide attempts among urban teenagers.

OBJECTIVE: To evaluate the relationship between dating violence, sexual assault, and suicide attempts among urban adolescents. DESIGN: Secondary analysis of the 2005 New York City Youth Risk Behavior Survey. SETTING: Eighty-seven New York City public high schools. PARTICIPANTS: Representative population-based sample of 8080 students, 14 years and older. MAIN EXPOSURES: Dating violence in the past year and lifetime history of sexual assault. OUTCOME MEASURE: One or more suicide attempts in the past year. RESULTS: Respondents were 50.0% female and primarily black (36.0%) or Hispanic (40.1%). In the past year, 11.7% of females and 7.2% of males reported 1 or more suicide attempts. Lifetime history of sexual assault was reported by 9.6% of females and 5.4% of males. Dating violence in the past year was reported by 10.6% of females and 9.5% of males. In multivariate models, controlling for persistent sadness, sexual orientation, and significant risk behaviors, recent dating violence (odds ratio, 1.61; 95% confidence interval, 1.05-2.47) was associated with suicide attempts in adolescent girls, while lifetime history of sexual assault (odds ratio, 3.86; 95% confidence interval, 2.11-7.06) was associated with suicide attempts in adolescent boys. CONCLUSIONS: In this population of urban youth, recent dating violence among females and lifetime history of sexual assault among males were significantly associated with suicide attempts. Clinicians and educators should be trained to routinely screen adolescents for violence victimization and should have a low threshold for referring these at-risk teenagers for mental health services.

Stage of change behavioral assessment tool fails to predict the prevalence of chlamydia in an urban adolescent health clinic.

STUDY OBJECTIVE: Strategies to reduce STI among adolescents and young adults have failed to consistently demonstrate effectiveness. A universal approach may not be appropriate because individuals are at different stages with respect to self-management behaviors. Thus, the Stage of Change Transtheoretical Model has been advocated. This study was conducted to determine whether staging could be accomplished in an urban adolescent clinic and whether it provides a tool to predict STI risk. DESIGN: Participants were interviewed and staged according to a standardized instrument with respect to sexual risk behaviors and contraceptive use. SETTING: Urban adolescent health clinic. PARTICIPANTS: 103 females (ages 18-24). INTERVENTIONS: A physical examination and diagnostic tests for syphilis, HSV, HCV, chlamydia, gonorrhea and HPV were performed. MAIN OUTCOME MEASURES: Stages for behaviors to reduce STI risk and to utilize contraception and STI prevalence. RESULTS: 78% of the participants were in the three earliest stages of behavior (precontemplative, contemplative, and ready for action) with respect to condom use for STI prevention; conversely only 47% were in early stages with respect to birth control practices. Of the participants tested, 12/81 (15%) had chlamydial infection detected by molecular techniques, whereas no participants had gonorrhoeae. Among the subset tested for HPV DNA, 18/45 (40%) were positive. The diagnostic behavior stage for STI prevention did not correlate with the presence of chlamydia. CONCLUSIONS: A staging instrument can be implemented into adolescent health clinic practice, but cannot be used as a risk assessment tool for the presence of chlamydia. Additionally females are more likely to protect themselves against pregnancy than against an STI.

Disclosure of date/acquaintance rape: who reports and when.

OBJECTIVE: To estimates rates and correlates of disclosure of date/acquaintance rape or attempted rape and verbally coercive sex among a diverse sample of adolescent and young adult females. DESIGN: Secondary data analysis of cross sectional data. SETTING: Urban adolescent healthcare facility. PARTICIPANTS: Adolescents who were identified as having experienced rape/attempted rape (n = 86) or verbally coerced sex (n = 68) in the last 12 months from study examining sexual violence. MAIN OUTCOME MEASURES: Disclosure of forced sex (logistic regression) and the timing of disclosure (survival analysis). INTERVENTIONS: None. RESULTS: Almost 60% of victims who experienced rape/attempted rape disclosed this information to one or more individuals, whereas only 47% of those who experienced verbally coerced sex told another person. Multivariate analyses found that drinking by the partner (AOR = 4.6) and shorter dating history (AOR = 6.3) were associated with disclosure of rape/attempted rape; timing of this disclosure was facilitated by Caucasian ethnicity (RR = 3.5), having a dating partner who drank > or = 1 drinks (RR = 2.5), and the perpetrator being someone other than the victim's boyfriend or partner (RR = 2.5). With regards to verbally coerced sex, reporting no pressure to use alcohol (AOR = 10.7) was the only factor associated with disclosure. No significant predictors of timing to disclosure were detected for this type of victimization. CONCLUSIONS: Perpetrator's alcohol use and a shorter dating history are important variables associated with disclosure of rape/attempted rape as well as timing to disclosure. Factors affecting the disclosure of verbally coerced sex and the latency associated with disclosure are less well defined.

The role of parental attitudes and provider discussions in uptake of adolescent vaccines.

The purpose of this study was to examine the relationship between parental vaccine attitudes, the number of specific vaccines discussed with a provider, and immunization outcomes including discussing immunization with their teen, knowledge of adolescent vaccine schedule, and their son or daughter being up-to-date on recommended vaccines using a nationally weight sample. Parents completed an internet-based survey between December 2012 and January 2013 and we computed a vaccine attitude scale (higher scores indicating stronger and more positive attitudes toward vaccination of teen) for each parent and categorized them into one of three groups: low (n=76), medium (n=207) or high (n=215). We also constructed a vaccine discussion scale representing the number of vaccines discussed with their adolescent's physician. Parents who were identified as having high vaccine attitudes were significantly more likely to report their physician talked with them about a particular vaccine. Using logistic regression and controlling for respondent's gender and age, income, and teen's gender, we found medium as compared to low-attitude parents had a 6.21 (95%CI=3.08, 12.51) greater odds of reporting that their teen had all recommended vaccines. Similarly, high as compared to low-attitude parents reported a 23.02 (95% CI=11.27, 46.99) greater odds of having a teen who was up-to-date on recommended vaccines. We detected that for each additional vaccine discussed, there was a 1.24 (95%CI=1.11, 1.39) increase in odds of the teen having all recommended vaccines. Parental immunization attitudes and provider discussion about vaccines are key ingredients to improving immunization rates among adolescents. While some parents may be reluctant to immunize their son or daughter with a recommended vaccine, vaccine-specific discussions between physicians and parents represent an important first step to continued discussions with providers regarding vaccination. Moreover, vaccine discussions must occur within the context of ongoing conversations about health and disease prevention.

School-based HPV immunization of young adolescents: effects of two brief health interventions.

Adolescent immunization rates for human papillomavirus (HPV) are low and interventions within school-based health centers (SBHCs) may increase HPV uptake and series completion. We examined the effect of a parent health message intervention on HPV vaccination intent, first dose uptake and series completion among adolescents who received care at SBHCs. Via computer-assisted telephone interviews (CATI), 445 parents of young adolescents were randomly assigned to 2 two-level interventions using a 2 × 2 design (rhetorical question (RQ) or no-RQ and one-sided or two-sided message). The RQ intervention involved asking the parent a question they were likely to endorse (e.g., "Do you want to protect your daughter from cervical cancer?") with the expectation that they would then behave in a manner consistent with their endorsement (i.e., agree to vaccinate). For the one-sided message, parents were given information that emphasized the safety and effectiveness of HPV vaccine, whereas the two-sided message acknowledged that some parents might have concerns about the vaccine, followed by reassurance regarding the safety and effectiveness. At CATI conclusion, parents indicated intentions to have their adolescents vaccinated. Parents who endorsed any intent were sent a consent form to return and all adolescents with signed returned consents were vaccinated at SBHCs. Medical records were reviewed for uptake/completion. Parents were 87% female; adolescents were 66% male and racially/ethnically diverse. 42.5% of parents indicated some intention to immunize, 51.4% were unsure, and 6.1% were not interested. 34% (n = 151) of adolescents received their first dose with series completion rates of 67% (n = 101). The RQ component of the intervention increased intention to vaccinate (RR = 1.45; 95%CI 1.16,1.81), but not first dose uptake or series completion. The 1-sided and 2-sided messages had no effect. This brief, RQ health intervention enhanced intent, but did not impact vaccination rates, likely due to the time delay between the intervention and consent form receipt.

Effect of abuse on health: results of a national survey.

HYPOTHESIS: The magnitude of risk would be highest for those reporting both types of abuse compared with those reporting 1 type or none. OBJECTIVE: To examine the independent associations between physical or sexual abuse or both and self-reported health status, mental health, and health-risk behaviors among a national school-based sample of adolescent girls. DESIGN: A secondary data analysis of a cross-sectional survey. SETTING: A nationally representative sample of 3015 girls in grades 5 through 12 from 265 public, private, and parochial schools (with an oversampling of urban schools) completed an anonymous survey conducted by the Commonwealth Fund Adolescent Health Survey. PATIENTS OR OTHER PARTICIPANTS: Girls were eligible for this study if they responded to 2 questions assessing past physical and sexual abuse. RESULTS: Among the respondents, 246 (8%) reported a history of physical abuse; 140 (5%), sexual abuse; and 160 (5%), both. Logistic regression controlling for grade, ethnicity, family structure, and socioeconomic status found that those who reported both types of abuse compared with those who did not report any were significantly more likely to experience moderate to severe depressive symptoms (adjusted odds ratio [AOR], 5.10), moderate to high levels of life stress (AOR, 3.28), regular smoking (AOR, 5.90), regular alcohol consumption (AOR, 3.76), use of other illicit drugs in the past 30 days (AOR, 3.44), and fair to poor health status (AOR, 1.74). Finally, girls who reported both types of abuse were 2.07 times more likely to report moderate to high depressive symptoms compared with those reporting only sexual abuse (95% confidence interval, 1.14-3.74). CONCLUSIONS: The magnitude of risk for adolescents reporting both types of abuse compared with no abuse is much greater than that for either abuse type alone. However, compared with both types, no significant increase in risk was detected in those reporting physical abuse only, and only depressive symptoms increased in those reporting sexual abuse only.

Prevalence and patterns of intimate partner violence among adolescent mothers during the postpartum period.

OBJECTIVE: To examine prevalence, frequency, severity, and patterns of intimate partner violence (IPV) during the first 24 months' post partum within a multiethnic cohort of adolescents. DESIGN: A prospective study of adolescent girls followed up for 24 months into the postpartum period. Follow-up surveys were completed at 3, 6, 12, 18, and 24 months' post partum. Overall, 74% completed at least 4 of the 5 follow-up surveys. SETTING: Postpartum unit at a university teaching hospital in Galveston, Tex. PARTICIPANTS: A total of 570 adolescents (18 years or younger; 219 Mexican Americans, 182 African Americans, and 169 European Americans) completed face-to-face interviews within 48 hours of delivery and returned at least 4 of 5 follow-up surveys. MAIN OUTCOME MEASURES: Prevalence of IPV and frequent and severe IPV. RESULTS: Prevalence of IPV was highest at 3 months' post partum (21%) and lowest at 24 months (13%). The percentage of assaulted mothers who experienced severe IPV increased from 40% to 62% across this period. Seventy-five percent of mothers reporting IPV during pregnancy also reported IPV within 24 months following delivery. Of importance, 78% who experienced IPV during the first 3 postpartum months had not reported IPV before delivery. Ethnic differences in IPV were observed at 3, 6, and 18 months' post partum. CONCLUSIONS: Adolescents are at high risk for experiencing IPV during the postpartum period. Frequent screening for IPV by health care practitioners is critical to maximize detection.

Rates and risk factors for sexual violence among an ethnically diverse sample of adolescents.

OBJECTIVES: To investigate the occurrence of rape/attempted rape and verbal sexual coercion among an ethnically diverse adolescent population and to evaluate whether unique risk factors existed for victims of either type of forced sexual experience. DESIGN: Cross-sectional survey assessing sexual violence within the past 12 months, behaviors that occurred on each subject's most recent date, and the occurrence of unwanted sexual experiences on any dates in the past year and details about that date. Subjects identified as experiencing either rape/attempted rape or verbal sexual coercion were compared with nonvictims using bivariate and multivariate analyses. SETTING: Urban adolescent health care facility. PARTICIPANTS: Female adolescents and young adults (n = 689) between the ages of 14 and 23 years who presented for care and met the eligibility criteria. RESULTS: Approximately 30% of young women reported having an unwanted sexual experience in the past year. The risk of rape/attempted rape was increased by past mild to moderate (adjusted odds ratio [AOR] = 4.27) or severe (AOR = 15.24) physical aggression by the dating partner; date-specific behaviors, including decreased level of romantic involvement (AOR = 0.63 per point decline) and going to the perpetrator's house to be alone (AOR = 3.01); past sexual victimization as an adolescent (AOR = 4.70); and lower levels of self-reported ethnic identity (AOR = 1.07 per point decline). More important, alcohol use by the victim or perpetrator was unrelated to an increased risk of rape/attempted rape. The risk of verbal sexual coercion was increased by past mild to moderate (AOR = 4.38) or severe (AOR = 13.79) verbal aggression from the dating partner; date-specific behaviors, including decreased level of romantic involvement (AOR = 0.70 per point decline) and greater number of past dates (AOR = 7.53); going to the perpetrator's house to be alone (AOR = 3.52); past sexual victimization as an adolescent (AOR = 9.83); pressures to use alcohol (AOR = 9.49); the victim not drinking alcohol during the date (AOR = 14.38); and increasing age discrepancy between victim and perpetrator (AOR = 1.23 per year increase). CONCLUSIONS: Approximately 1 in 4 urban young women reported having experienced verbal sexual coercion or rape/attempted rape by a date or acquaintance in the past year. Distinct risk profiles for rape/attempted rape and verbal sexual coercion were identified when compared with those who did not report any victimization.

Effects of hormonal contraception on bone mineral density after 24 months of use.

OBJECTIVE: To measure the effect of 24 months of depot medroxyprogesterone acetate use on bone mineral density compared with oral contraception (pills) and nonhormonal contraception. METHODS: Women aged 18-33 years self-selected oral contraception, depot medroxyprogesterone acetate, or nonhormonal contraception (controls). Those selecting pills were randomized to formulations containing either 35 microg ethinyl estradiol and norethindrone or 30 microg ethinyl estradiol and desogestrel. Controls were frequency matched on age and race/ethnicity to hormonal contraception users. Dual-energy X-ray absorptiometry of the lumbar spine (L1-L4) was performed at baseline, 12 months, and 24 months. Percent change in bone mineral density was analyzed by using analysis of covariance, adjusting for age, race/ethnicity, weight-bearing exercise, calcium intake, smoking status, and body mass index. RESULTS: Of the 191 women making up the final sample, 86 used pills, 47 used depot medroxyprogesterone acetate, and 58 used nonhormonal contraception. Women using depot medroxyprogesterone acetate for 24 months experienced, on average, a 5.7% loss in bone mineral density, with a 3.2% loss occurring between months 12 and 24. On average, users of desogestrel pills experienced a 2.6% loss in bone mineral density after 24 months. Bonferroni-adjusted pairwise comparisons demonstrated that bone mineral density changes from baseline to 24 months among depot medroxyprogesterone acetate users differed significantly from changes experienced by either of the pill groups or the control group. Changes in bone mineral density among users of either pill did not significantly differ from each other or from controls. CONCLUSION: Loss of bone mineral density associated with depot medroxyprogesterone acetate use appears to be linear during the first 2 years of use. Shifts in bone mineral density among pill users were not significant when compared with controls.
