Background Multimorbidity is increasing among adults in the United States. Yet limited research has examined multimorbidity clusters in persons aged 50 years and older with and without a history of cancer. An increased understanding of multimorbidity clusters may improve the cancer survivorship experience for survivors with multimorbidity. Methods We identified 7580 adults aged 50 years and older with 2 or more diseases—including 811 adults with a history of primary breast, colorectal, cervical, prostate, or lung cancer—from the 2018 National Health Interview Survey. Exploratory factor analysis identified clusters of multimorbidity among cancer survivors and individuals without a history of cancer (controls). Frequency tables and chi-square tests were performed to determine overall differences in sociodemographic characteristics, health-related characteristics, and multimorbidity between groups. Results Cancer survivors reported a higher prevalence of having 4 or more diseases compared to controls (57% and 38%, respectively). Our analysis identified 6 clusters for cancer survivors and 4 clusters for controls. Three clusters (pulmonary, cardiac, and liver) included the same diseases for cancer survivors and controls. Conclusions Diseases clustered differently across adults ≥ 50 years of age with and without a history of cancer. Findings from this study may be used to inform clinical care, increase the development and dissemination of multilevel public health interventions, escalate system improvements, and initiate innovative policy reform.

BackgroundLonger intervals between prostate-specific antigen (PSA) tests for routine prostate cancer screening can reduce the harms while maintaining the benefits of screening. Limited information has been published on PSA screening frequency. The purpose of this report is to describe the number of PSA tests in the last 5 years reported by men in the United States.MethodsUsing data from National Health Interview Survey Cancer Control Supplements in 2010, 2015, and 2018, the number of PSA tests in the last 5 years reported by men ≥40 years was categorized as 4 to 5 PSA tests, 1 to 3 PSA tests, and no PSA tests. Logistic regression was used to calculate model-adjusted prevalence risk ratios (aPRs) for the number of PSA tests in the last 5 years, adjusting for age, racial-ethnic group, education, marital status, and health insurance.ResultsThe proportion of men aged ≥70 years who reported 4 to 5 PSA tests in the last 5 years decreased from 37.2% in 2010 to 31.1% in 2018, while the proportion reporting 1 to 3 PSA tests increased from 25.5% to 31.9%. In 2018, aPRs for 4 to 5 PSA tests vs. 1 to 3 PSA tests in the last 5 years were significantly higher among men aged 70 to 79 years than among men aged 55 to 69 years.ConclusionsMen aged ≥70 years reported a small shift to less intense PSA testing between 2010 and 2018, but PSA testing intensity remained higher in men aged ≥70 years than in men aged 55 to 69 years.

Introduction Little is known about perceived health status and behavioral risk factors among prostate cancer survivors. The objective of this study was to describe racial and ethnic differences in self-reported health status, chronic conditions, and selected behavioral risk factors among prostate cancer survivors in the US. Methods We used data from the 2015 National Health Interview Survey to calculate the prevalence of various levels of health status, chronic conditions, behavioral risk factors, and sociodemographic characteristics among prostate cancer survivors aged 50 years or older. We stratified results by race and ethnicity. Results Of the 317 prostate cancer survivors in our sample, 33.1% reported no physical activity, 64.2% reported being current drinkers, 26.1% characterized their drinking as moderate/heavy, 42.3% reported being former smokers, and 8.7% were current smokers. Nearly one-third (29.1%) of survivors were obese (body mass index ≥30), and 15.1% had 3 to 6 chronic conditions. A greater percentage of White (29.7%) than Black (14.2%) or Hispanic (16.3%) survivors were moderate/heavy drinkers. A greater percentage of Black (16.2%) than White (7.5%) or Hispanic (7.3%) survivors were current smokers. A greater percentage of Black (25.1%) or Hispanic (27.7%) than White (11.4%) survivors had 3 to 6 chronic conditions. Conclusion As the population of older men increases, prostate cancer diagnoses and those surviving the disease will also increase. Significant racial and ethnic group differences in behavioral risk factors and chronic conditions exist among prostate cancer survivors. Public health could prioritize efforts to improve health behaviors among prostate cancer survivors and use targeted interventions to address disparities.

Introduction Screening can decrease colorectal cancer incidence and mortality and is recommended in clinical practice guidelines. Poor quality of colorectal cancer screening can negate the benefit of screening. The objective of this study was to assess the quality of screening services provided by the Centers for Disease Control and Prevention's Colorectal Cancer Control Program from July 2009 through June 2015. Methods We collected data from the program's 29 grantees, funded to provide colorectal cancer screening and diagnostic services to asymptomatic, low-income, and underinsured or uninsured adults aged 50 to 64. We collected data on the dates and results of all screening and diagnostic tests and, for colonoscopies, on whether the cecum was reached, whether bowel preparation was adequate, and endoscopists' recommendations for the next test. Results Overall, 82.9% (range among grantees, 50.0%-97.2%) of positive FOBTs/FITs were followed up by colonoscopy; 95.2% of colonoscopies occurred within 180 days of the positive stool test. Cecal intubation rates ranged among grantees from 94.2% to 100%. Adenoma detection rates met recommended threshold levels for almost all grantees. Recommendations for rescreening and surveillance intervals deviated from guidelines in both directions. Of clients with normal colonoscopies, 85.3% (range, 37.7%-99.7%) were told to return in 10 years, as recommended in national guidelines. Of clients with advanced adenomas, 55.2% (range, 20.0%-84.6%) were told to return in 3 years as recommended, 25.4% (range, 3.8%-56.6%) in 5 or more years, and 18.6% (range, 0%-47.2%) in less than 3 years. Conclusion Although overall screening quality was good, it varied considerably. Ongoing monitoring to identify performance problems is essential for all colorectal cancer screening activities, so that efforts designed to improve performance can be targeted to individual clinicians.

Introduction Prior studies suggest overuse of nonrecommended lung cancer screening tests in U.S. community practice and underuse of recommended tests. Methods Data from the 2010 and 2015 National Health Interview Surveys was analyzed from 2016 to 2018. Prevalence, populations, and number of chest computed tomography (CT) and chest x-ray tests were estimated for people who did and did not meet U.S. Preventive Services Task Force (USPSTF) criteria for lung cancer screening, among people aged ≥40 years without lung cancer. Results In 2015, among those who met USPSTF criteria, 4.4% (95% CI=3.0%, 6.6%), or 360,000 (95% CI=240,000, 535,000) people reported lung cancer screening with a chest CT; and 8.5% (95% CI=6.5%, 11.1%), or 689,000 (95% CI=526,000, 898,000) people reported a chest x ray. Among those who did not meet USPSTF criteria, 2.3% (95% CI=2.0%, 2.6%), or 3,259,000 (95% CI=2,850,000, 3,724,000) people reported a chest x ray; and 1.3% (95% CI=1.1%, 1.5%), or 1,806,000 (95% CI=1,495,000, 2,173,000) people reported a chest CT. The estimated population meeting USPSTF criteria for lung cancer screening in 2015 was 8,098,000 (95% CI=7,533,000, 8,702,000), which was smaller than the 9,620,000 people (95% CI=8,960,000, 10,325,000) in 2010. Conclusions The number of adults inappropriately screened for lung cancer greatly exceeds the number screened according to USPSTF recommendations, the prevalence of appropriate lung cancer screening is low, and the population meeting USPSTF criteria is shrinking. To realize the potential benefits of screening, better processes to appropriately triage eligible individuals to screening, plus screening with a USPSTF-recommended test, would be beneficial.

OBJECTIVE: In 2016, 19% of HIV diagnoses were in women. About 40% of HIV infections in women aged 18-34 years have been attributed to anal sex, suggesting that women who report high risk behaviors such as anal sex might benefit from HIV testing and prevention with preexposure prophylaxis (PrEP). In this analysis, we estimated HIV testing rates among women who reported anal sex. STUDY DESIGN: We analyzed data from the 2011-2015 National Survey of Family Growth to estimate the proportion of sexually active, nonpregnant US women aged 15-44 years who had an HIV test within the past year, stratified by those who reported anal sex and other risk factors, including >= 2 sexual partners, condomless sex with a new partner or multiple partners, gonorrhea in the past year, or any history of syphilis. RESULTS: Overall, 7.9 million of 42.4 million sexually active, nonpregnant US women (18.7%) reported an HIV test within the past year. Among 42.4 million sexually active women, 9.0 million (20.1%) reported they had anal sex in the past year. Among these 9.0 million women, 19.2% reported that their providers asked about their type of intercourse, and 20.1% reported an HIV test within the past year. Overall, HIV testing was higher among women who reported anal sex and reported that their providers asked about type of sex than those whose provider did not ask (37.8% vs 15.9%; P <.001). HIV testing in the past year was higher for women with other risk behaviors compared with anal sex, ranging from 35.8% to 47.2%. CONCLUSION: Overall, HIV testing rates within the past year were low among women with sexual behaviors that increase their risk of acquiring HIV and especially low among those who reported anal sex. Early detection and treatment of HIV, and HIV prevention with PrEP, are effective health services that protect women's health and well-being but that can be offered only based on HIV testing results. Women's health care providers are uniquely poised to assess risk for acquiring HIV, including taking a sexual history that asks about anal sex, and performing HIV testing to identify women who need HIV treatment or might benefit from PrEP.

Objectives: African American girls in juvenile detention are disproportionately affected by sexually transmitted diseases (STDs) and other psychosocial health problems, yet few studies have examined associations between experiencing multiple psychosocial health problems and sexual risk behaviors and STD diagnosis. Method: The study included 188 detained African American girls aged 13-17 years. We conducted three sets of logistic regressions. First, bivariate analyses assessed associations among seven psychosocial factors (substance use disorder; depression; post-traumatic stress disorder [PTSD]; emotional abuse; pregnancy coercion; physical abuse; and sexual abuse) and four outcomes (early sexual initiation; condomless sex; multiple sexual partners; self-reported STD) to examine their interrelationships. Second, we examined associations between experiencing multiple psychosocial factors and outcomes. Third, psychosocial factors were categorized into four domains: substance use disorder; mental health (depression, PTSD); psychological abuse (emotional abuse, pregnancy coercion); and violence (physical abuse, sexual abuse) and included as independent associations with each outcome to assess their relative importance. Results: Multiple interrelationships among psychosocial factors and outcomes were identified. An increase of one psychosocial health problem was associated with an 18% to 27% increased odds of sexual risk behaviors or a previous STD diagnosis. Reporting violence was associated with increased odds of having multiple partners (odds ratio = 3.31; confidence interval = 1.57-6.97), and experiencing psychological abuse was associated with increased odds of reporting an STD diagnosis (odds ratio = 3.95; confidence interval = 1.62-9.63). Conclusion: Multiple psychosocial health problems, particularly psychological abuse and violence, are associated with sexual risk and STDs in this vulnerable population.

HIV infection disproportionately affects Blacks in the southern United States (U.S.), a region where legal policies that may unintentionally impede earlier HIV detection and treatment are prevalent. Historically Black Colleges and Universities (HBCUs) have historically facilitated social change in communities of color and have been underexplored as partners for HIV prevention. We describe geographic and social determinants of health (SDH) in the southern U.S. to inform potential HBCU-public health partnerships that might improve HIV health equity. We evaluated the relationship between county-level HIV prevalences (2013), HBCU geographic coordinates, and SDH variables in the southern counties with HBCUs. U.S. Census-derived SDH variables included race/ethnicity (i.e., Black, White, Hispanic), unemployment, female head of household, poverty, percent owner-occupied housing units, urbanicity, and primary care provider rates. Associations were assessed using bivariate and multivariable linear regression. Of 104 HBCUs in the contiguous U.S., 100 (96%) were located in 69 southern counties with average Black populations of 40% and an average HIV prevalence of 615. 5 per 100,000, over two times the national rate (295.1 per 100,000). In bivariable analyses, higher HIV rates in these counties were associated with higher percent Black population, unemployment, female head of household, poverty, fewer owner-occupied housing units, and greater urbanicity (p < 0.05). In multivariable analyses, counties with higher HIV rates had higher percentages of Blacks, greater urbanicity, fewer owner-occupied housing units, and more female heads of households (p < 0.05). The southern U.S. is disproportionately affected by HIV, and many HBCUs are located in affected southern counties. HBCUs may be important public health partners for helping to develop structural interventions that strengthen HIV policies in support of health equity in these southern, mostly urban counties.

Rates of teenage pregnancy remain high in sub-Saharan Africa. The KEMRI Health and Demographic Surveillance System provided the sampling frame for a survey. Analysis focused on 1,952 girls aged 13–19 years. Over a third (37.2%; n = 727) were sexually active and 23.3% (n = 454) had ever been pregnant. Adjusted odds of reporting a history of pregnancy were greater for older compared to younger teens, teens who were ever married or cohabiting compared to those who were single, teens with a primary education or less compared to those with a higher level of education, and teens who experienced partner violence in the last 12 months. Three-quarters of teens pregnant in the last 12 months did not want to get pregnant (n = 190); only 64.2% (n = 122) answered yes to using any family planning method. Teen pregnancy and its consequences are serious public health issues. Higher education levels are a crucial component to address the problem.

Using the HIV Incident Risk Index for men who have sex with men—an objective and validated measure of risk for HIV acquisition, and self-perceptions of belief and worry about acquiring HIV, we identified individuals who underestimated substantial risk for HIV. Data from a racially/ethnically diverse cohort of 324 HIV-negative episodic substance-using men who have sex with men (SUMSM) enrolled in a behavioral risk reduction intervention (2010–2012) were analyzed. Two hundred and fourteen (66%) SUMSM at substantial risk for HIV were identified, of whom 147 (69%, or 45% of the total sample) underestimated their risk. In multivariable regression analyses, compared to others in the cohort, SUMSM who underestimated their substantial risk were more likely to report: a recent sexually transmitted infection diagnosis, experiencing greater social isolation, and exchanging sex for drugs, money, or other goods. An objective risk screener can be valuable to providers in identifying and discussing with SUMSM factors associated with substantial HIV risk, particularly those who may not recognize their risk.

Objective: To assess whether state criminal exposure laws are associated with HIV and stage 3 (AIDS) diagnosis rates in the United States.Design: We assessed the relationship between HIV and stage 3 (AIDS) diagnosis data from the National HIV Surveillance System and the presence of a state criminal exposure law as identified through WestlawNext by using generalized estimating equations.Methods: We limited analysis to persons aged at least 13 years with diagnosed HIV infection or AIDS reported to the National HIV Surveillance System of the Centers for Disease Control and Prevention. The primary outcome measures were rates of diagnosis of HIV (2001-2010 in 33 states) and AIDS (1994-2010 in 50 states) per 100 000 individuals per year. In addition to criminal exposure laws, state-level factors evaluated for inclusion in models included income, unemployment, poverty, education, urbanicity, and race/ethnicity.Results: At the end of the study period, 30 states had laws criminalizing HIV exposure. In bivariate models (P < 0.05), unemployment, poverty, education, urbanicity, and race/ethnicity were associated with HIV and AIDS diagnoses. In final models, proportion of adults with less than a high school education and percentage of the population living in urban areas were significantly associated with HIV and AIDS diagnoses over time; criminal exposure laws were not associated with diagnosis rates.Conclusion: We found no association between HIV or AIDS diagnosis rates and criminal exposure laws across states over time, suggesting that these laws have had no detectable HIV prevention effect.

This study uses county-level surveillance data to systematically analyze geographic variation and clustering of persons living with diagnosed HIV (PLWH) in the southern United States in 2011. Clusters corresponding to large metropolitan areas - including Miami, Atlanta, and Baltimore - had HIV prevalence rates higher (p<.001) than the regional rate. Regression analysis within the counties included in these clusters determined that race was a significant indicator for PLWH. These results provide a general picture of the distribution of PLWH in the southern United States at the county level and provide insights for identifying local geographic areas with a high number of PLWH, as well as subpopulations that may have an increased risk of infection.

The purpose of this study was to examine the social and behavioral factors associated with pregnancy history among a sample of African American adolescent girls recruited from a short-term juvenile detention center in order to better understand the needs of this vulnerable population. Data were collected from a sample of 188 detained African American, 13-17-year-old girls in Atlanta, Georgia, who participated in a larger HIV prevention study. An audio computer-assisted self-interviewing survey was completed by participants to obtain information on socioecological factors to include individual, parental/familial, sexual risk, psychosocial, and substance use factors. Among the 188 participants, 25.5 % reported a history of pregnancy. A multivariable logistic regression model showed that girls with a history of pregnancy were more likely to live in a household receiving government aid, use hormonal contraceptives at last sex, participate in sex trading, have casual sex partners, have condomless sex in the past 90 days, and have a history of physical abuse. Girls with no history of pregnancy were more likely to have been incarcerated at least twice and to have previously used alcohol. Detention-based interventions and pregnancy prevention programs for this vulnerable population may benefit by addressing factors related to sexual behavior and development, substance use, individual background, and psychosocial health.

Community-based organizations (CBOs) are critical to delivery of effective HIV prevention because of their reach to key populations. This online survey of a national sample of CBOs assessed their awareness of, interest in, and resources needed to provide nonoccupational postexposure prophylaxis (nPEP), preexposure prophylaxis (PrEP), and HIV treatment as prevention (TasP). One hundred seventy-five CBOs participated: 87 clinical and 88 nonclinical CBOs. For nPEP, PrEP, and TasP, program managers reported that awareness was high (94%, 90%, 85%), meeting current client need was low (20%, 13%, 18%), and the likelihood of increasing their current provision with additional resources was somewhat high (62%, 64%, 62%). Clinical CBOs were more prepared to support expansion of these biomedical interventions than nonclinical CBOs. Meeting the information, training, and resource needs of CBOs is critical for effective collaboration to reduce the number of new HIV infections through expanded delivery of PrEP, nPEP, and TasP.

This study examined study product adherence and its determinants in the Botswana oral pre-exposure prophylaxis efficacy trial. Among the 1,219 participants, the mean adherence by pill count and 3-day self-report was 94 % for each. In multivariable models, pill count adherence was significantly associated with adverse events (nausea, dizziness, vomiting) (RR 0.98 95 % CI 0.98–1.00; p = 0.03) and side effect concerns (RR 0.98 95 % CI 0.96–0.99; p = 0.01). Self-reported adherence was significantly associated with having an HIV-positive partner (RR 1.02 95 % CI 1.00–1.04; p = 0.02) and Francistown residence (RR 0.98 95 % CI 0.96, 0.99; p = 0.0001). Detectable drug concentrations showed modest associations with self-report and pill count adherence, and drug levels were higher among those self-reporting 100 % adherence than those reporting <100 %. Most common adherence barriers involved refill delays and other logistic challenges; cellphone alarm reminder use was the most common facilitator.

For the past three decades, legislative approaches to prevent HIV transmission have been used at the national, state, and local levels. One punitive legislative approach has been enactment of laws that criminalize behaviors associated with HIV exposure (HIV-specific criminal laws). In the USA, HIV-specific criminal laws have largely been shaped by state laws. These laws impose criminal penalties on persons who know they have HIV and subsequently engage in certain behaviors, most commonly sexual activity without prior disclosure of HIV-positive serostatus. These laws have been subject to intense public debate. Using public health law research methods, data from the legal database WestlawNext© were analyzed to describe the prevalence and characteristics of laws that criminalize potential HIV exposure in the 50 states (plus the District of Columbia) and to examine the implications of these laws for public health practice. The first state laws were enacted in 1986; as of 2011 a total of 67 laws had been enacted in 33 states. By 1995, nearly two-thirds of all laws had been enacted; by 2000, 85 % of laws had been enacted; and since 2000, an additional 10 laws have been enacted. Twenty-four states require persons who are aware that they have HIV to disclose their status to sexual partners and 14 states require disclosure to needle-sharing partners. Twenty-five states criminalize one or more behaviors that pose a low or negligible risk for HIV transmission. Nearly two-thirds of states in the USA have legislation that criminalizes potential HIV exposure. Many of these laws criminalize behaviors that pose low or negligible risk for HIV transmission. The majority of laws were passed before studies showed that antiretroviral therapy (ART) reduces HIV transmission risk and most laws do not account for HIV prevention measures that reduce transmission risk, such as condom use, ART, or pre-exposure prophylaxis. States with HIV-specific criminal laws are encouraged to use the findings of this paper to re-examine those laws, assess the laws’ alignment with current evidence regarding HIV transmission risk, and consider whether the laws are the best vehicle to achieve their intended purposes.

Sampling hard-to-reach populations can be difficult with traditional survey methods. Challenges arise because sampling frames are typically unknown, and individuals can be wary of authority or afraid of being identified by the stigmatized or illegal nature of their behaviors. A contemporary solution is respondent-driven sampling (RDS), a survey method spearheaded by Heckathorn (1997) that utilizes links in underlying social networks to create branching referral chains of respondents. Obtaining samples for the target population is heavily impacted by RDS parameters, such as field site and the location of the initial respondents (“seeds”). However, the relationship between the RDS parameters and the eventual sample is not yet thoroughly understood. This paper reviews spatial patterns in two RDS samples from Chicago and New Orleans to determine the relative importance of seed and field site location, as well as assess the impact of physical barriers.

Both air pollution exposure and socioeconomic status (SES) are important indicators of children’s health. Using highly resolved modeled predictive surfaces, we examine the joint effects of air pollution exposure and measures of SES in a population level analysis of pregnancy outcomes in North Carolina (NC).

Few HIV/STI interventions exist for African American adolescent girls in juvenile detention. The objective was to evaluate the efficacy of an intervention to reduce incident STIs, improve HIV-preventive behaviors, and enhance psychosocial outcomes. We conducted a randomized controlled trial among African American adolescent girls (13-17 years, N = 188) in juvenile detention from March 2011 to May 2012. Assessments occurred at baseline and 3- and 6-months post-randomization and included: audio computer-assisted self-interview, condom skills assessment, and self-collected vaginal swab to detect Chlamydia and gonorrhea. The Imara intervention included three individual-level sessions and four phone sessions; expedited partner therapy was offered to STI-positive adolescents. The comparison group received the usual care provided by the detention center: STI testing, treatment, and counseling. At the 6-month assessment (3-months post-intervention), Imara participants reported higher condom use self-efficacy (p < 0.001), HIV/STI knowledge (p < 0.001), and condom use skills (p < 0.001) compared to control participants. No significant differences were observed between trial conditions in incident Chlamydia or gonorrhea infections, condom use, or number of vaginal sex partners. Imara for detained African American adolescent girls can improve condom use skills and psychosocial outcomes; however, a critical need for interventions to reduce sexual risk remains.

Girls in juvenile detention have high rates of adverse sexual health outcomes, including pregnancy and sexually transmitted infections (STIs). Few studies have examined associations between pregnancy history and STI acquisition. The objective was to examine pregnancy history as a predictor of STI acquisition over 6 months of follow-up among African American girls recruited from juvenile detention centers. Non-pregnant, sexually active, African American girls (n = 188), 13-17 years, were recruited from short-term juvenile detention centers and enrolled in a randomized controlled HIV/STI prevention trial. Data were collected at baseline and 3- and 6-month follow-up assessments. At each assessment, participants completed an audio computer-assisted self-interview and provided a self-collected vaginal swab specimen assayed for Chlamydia and gonorrhea. The analytic sample included participants completing = 1 follow-up assessment. T-tests and chi-square statistics compared selected baseline characteristics among participants who did and did not report a pregnancy history at baseline. Logistic regression models examined associations between baseline pregnancy history and STI acquisition, defined as a positive STI test result during follow-up subsequent to a negative result or documented treatment. Adjusted models controlled for age and baseline differences significant at p < 0.1 among participants with and without a pregnancy history. Adjusted analyses did not include study condition since it was not associated with unprotected sex, STI acquisition nor pregnancy history. Of 179 (95.2%) participants who completed = 1 follow-up assessment, 45 (25.1%) reported a history of pregnancy. Of those 45, 66.7% reported 1 pregnancy, and 44.4% reported a live birth; 55.6% reported their current age as their age during their last pregnancy. At baseline, girls with a pregnancy history were more likely to report living in household receiving government assistance (82.2% vs. 66.4%, p = 0.045), a history of physical abuse (53.3% vs. 38.1%, p = 0.072), male sex partners = 4 years older (20% vs. 15.5%, p = 0.098), a casual partner (48.9% vs. 31.3%, p = 0.034), vaginal sex without a condom in the past 90 days (77.8% vs. 51.5%, p = 0.002) and hormonal contraceptive use at last sex (44.4% vs. 20.2%, p = 0.001). They also reported higher levels of stress (p = 0.005). Nearly half (48.9%) of girls with and 30.6% without a pregnancy history acquired an STI during follow-up (p = 0.026). In adjusted analyses, a history of pregnancy was associated with an increased likelihood of STI acquisition (AOR: 2.6, 95% CI: 1.2, 5.9). A high proportion of sexually active detained African American girls reported a history of pregnancy. A history of pregnancy independently predicted laboratory-confirmed STI acquisition over a 6-month follow-up period. Future prevention efforts may benefit by addressing the unique needs of detained African American girls with a history of pregnancy. Research exploring mechanisms by which pregnancy history is associated with elevated STI risk may aid development of prevention interventions for this population.
