Trained counselors interviewed 192 women who had been trafficked and sexually exploited about abuse and evaluated their physical and mental health status within 14 days of entry into posttrafficking services. Most reported physical or sexual violence while trafficked (95%), pre-trafficking abuse (59%), and multiple posttrafficking physical and psychological problems. Newly identified trafficked women require immediate attention to address posttrauma symptoms and adequate recovery time before making decisions about participating in prosecutorial or immigration proceedings or returning home.

IMPORTANCE Human trafficking and exploitation of children have profound health consequences. To our knowledge, this study represents the largest survey on the health of child and adolescent survivors of human trafficking. OBJECTIVE To describe experiences of abuse and exploitation, mental health outcomes, and suicidal behavior among children and adolescents in posttrafficking services. We also examine how exposures to violence, exploitation, and abuse affect the mental health and suicidal behavior of trafficked children. DESIGN, SETTING, AND PARTICIPANTS A survey was conducted with 387 children and adolescents aged 10 to 17 years in posttrafficking services in Cambodia, Thailand, or Vietnam, which along with Laos, Myanmar, and Yunnan Province, China, compose the Greater Mekong Subregion. Participants were interviewed within 2 weeks of entering services from October 2011 through May 2013. MAIN OUTCOMES AND MEASURES Depression, posttraumatic stress disorder, anxiety, suicidal ideation, self-injury, and suicide attempts. RESULTS Among the 387 children and adolescent study participants, most (82%) were female. Twelve percent had tried to harm or kill themselves in the month before the interview. Fifty-six percent screened positive for depression, 33% for an anxiety disorder, and 26% for posttraumatic stress disorder. Abuse at home was reported by 20%. Physical violence while trafficked was reported by 41% of boys and 19% of girls. Twenty-three percent of girls and 1 boy reported sexual violence. Mental health symptoms were strongly associated with recent self-harm and suicide attempts. Severe physical violence was associated with depression (adjusted odds ratio [AOR], 3.55; 95% CI, 1.64-7.71), anxiety (AOR, 2.13; 95% CI, 1.12-4.05), and suicidal ideation (AOR, 3.68; 95% CI, 1.77-7.67). Sexual violence while trafficked was associated with depression (AOR, 2.27; 95% CI, 1.22-4.23) and suicidal ideation (AOR, 3.43; 95% CI, 1.80-6.54). CONCLUSIONS AND RELEVANCE Children and adolescents in posttrafficking care showed high symptom levels of depression, anxiety, and posttraumatic stress disorder, which are strongly associated with self-harm or suicidal behaviors. Mental health screening and reintegration risk assessments are critical components of posttrafficking services, especially in planning for family reunification and other social integration options.

OBJECTIVES This article reviews the available evidence regarding the efficacy, effectiveness, ethics, and sustainability of approaches to strengthen systems to care for and protect children living outside family care in low- and middle-income countries. METHOD For trafficked children, children of and on the street, children of conflict/disaster, and institutionalized children, a systems framework approach was used to organize the topic of sustainable approaches in low- and middle-income countries and addresses the following: legislation, policies, and regulations; system structures and functions (formal and informal); and continuum of care and services. The article draws on the findings of a focal group convened by the U.S. Government Evidence Summit: Protecting Children Outside of Family Care (December 12-13, 2011, Washington, DC), tasked with reviewing the literature on systems, strategies, and interventions for sustainable long-term care and protection of children with a history of living outside of family care in low- and middle-income country contexts. The specific methodology for the review is described in the commentary paper (Higgs, Zlidar, & Balster, 2012) that accompanies these papers. RESULTS For the most part, the evidence base in support of sustainable long-term care for the populations of interest is relatively weak, with some stronger but unreplicated studies. Some populations have been studied more thoroughly than others, and there are many gaps. Most of the existing studies identify population characteristics, needs, and consequences of a lack of systemic services to promote family-like care. There is some evidence of the effectiveness of laws and policies, as well as some evidence of service effectiveness, in improving outcomes for children outside of family care. CONCLUSIONS Despite the weaknesses and gaps of the existing research, there is a foundation of research for going forward, which should focus on developing and implementing systems for these most vulnerable children. The evidence reviewed indicates that child protection systems should aim for appropriate, permanent family care (including reunification, adoption, kinship care, or kafalah) for children in order to secure the best environment for a childs developmental prospects. Evidence also suggests that the quality and duration of care, including both permanent family care and alternative care, are important regardless of setting. The diversity of political, socioeconomic, historical, regional, community, and cultural contexts in which child protection systems operate need to be taken into account during programming and research design.

OBJECTIVES We conducted a large-scale study of newly arrived refugee children in the United States with data from 2006 to 2012 domestic medical examinations in 4 sites: Colorado; Minnesota; Philadelphia, Pennsylvania; and Washington State. METHODS Blood lead level, anemia, hepatitis B virus (HBV) infection, tuberculosis infection or disease, and Strongyloides seropositivity data were available for 8148 refugee children (aged < 19 years) from Bhutan, Burma, Democratic Republic of Congo, Ethiopia, Iraq, and Somalia. RESULTS We identified distinct health profiles for each country of origin, as well as for Burmese children who arrived in the United States from Thailand compared with Burmese children who arrived from Malaysia. Hepatitis B was more prevalent among male children than female children and among children aged 5 years and older. The odds of HBV, tuberculosis, and Strongyloides decreased over the study period. CONCLUSIONS Medical screening remains an important part of health care for newly arrived refugee children in the United States, and disease risk varies by population.

Background: The time-limited nature of health and public health research fellowships poses a challenge to trainees’ and community partners’ efforts to sustain effective, collaborative, community-based participatory research (CBPR) relationships.Objectives: This paper presents CBPR case studies of partnerships between health services research trainees and community organization leaders in a medium-sized city to describe how participation in the partnership altered community partners’ understanding and willingness to conduct research and to engage with research-derived data.Methods: Trainees and faculty used participatory methods with community leaders to identify research questions, and conduct and disseminate research. Throughout the process, trainees and faculty included research capacity building of community partners as a targeted outcome. Community partners were asked to reflect retrospectively on community research capacity building in the context of CBPR projects. Reflections were discussed and categorized by the authorship team, who grouped observations into topics that may serve as a foundation for development of future prospective analyses.Results: Important ideas shared include that trainee participation in CBPR may have an enduring impact on the community by increasing the capacity of community partners and agencies to engage in research beyond that which they are conducting with the current trainee.Conclusion: We posit that CBPR with research trainees may have an additive effect on community research capacity when it is conducted in collaboration with community leaders and focuses on a single region. More research is needed to characterize this potential outcome.

OBJECTIVES We examined the impact of a maternal-child home visitation program on birth spacing for first-time Latina mothers, focusing on adolescents and women who identified as Mexican or Puerto Rican. METHODS This was a retrospective cohort study. One thousand Latina women enrolled in the Pennsylvania Nurse-Family Partnership between January 1, 2003, and December 31, 2007, were matched to nonenrolled Latina women using propensity scores. The primary outcome was the time to second pregnancy that resulted in a live birth (interpregnancy interval). Proportional hazards models and bootstrap methods compared the time to event. RESULTS Home visitation was associated with a small decrease in the risk of a short interpregnancy interval (≤ 18 months) among Latina women (hazards ratio [HR] = 0.86; 95% confidence interval [CI] = 0.75, 0.99). This effect was driven by outcomes among younger adolescent women (HR = 0.80; 95% CI = 0.65, 0.96). There was also a trend toward significance for women of Mexican heritage (HR = 0.74; 95% CI = 0.49, 1.07), although this effect might be attributed to individual agency performance. CONCLUSIONS Home visitation using the Nurse-Family Partnership model had measurable effects on birth spacing in Latina women.

OBJECTIVES We describe trends in receipt of preventive dental care among Medicaid-enrolled children in Pennsylvania between 2005 and 2010, comparing the US children of immigrants with their co-ethnic peers in nonimmigrant families. METHODS We analyzed Pennsylvania Medicaid claims, birth records, and census data for children born in Pennsylvania and enrolled in Medicaid for 10 or more months during any of the calendar years assessed. RESULTS Receipt of preventive dental care was more likely among Latino children in immigrant families than among their peers in nonimmigrant families; also, it was more likely among White children in immigrant families than among their peers in nonimmigrant families. Rates of preventive dental care use among African American and Asian children in immigrant and nonimmigrant families were comparable. From 2005 to 2010, the percentage of Latino children in nonimmigrant families who received preventive dental care increased from 33% to 61%. Changes in other groups were significant but less dramatic. CONCLUSIONS Receipt of preventive dental care has increased among Medicaid-enrolled children in Pennsylvania, with marked gains among Latino children. Within each racial/ethnic group, the children of immigrants were either more likely than or equally likely as children in nonimmigrant families to receive care.

SETTING Philadelphia, PA, USA. OBJECTIVES To compare the evaluation and treatment of latent tuberculous infection (LTBI) in refugees seen at member clinics of the Philadelphia Refugee Health Collaborative (PRHC) vs. non-PRHC clinics. DESIGN Refugees with Class B (non-communicable) tuberculosis (TB) admitted to the United States from 2010 to 2012 who were being treated at PRHC clinics were compared to those treated at non-PRHC clinics. Odds ratios (ORs) for attending a follow-up appointment, completing treatment, and time from arrival to the United States to the first TB screening test were calculated. RESULTS Of the 2094 refugees who arrived in Philadelphia in 2010-2012, the Philadelphia Department of Public Health was notified of 149 who required additional evaluation for TB. Among these, 57 (38.3%) were confirmed to have LTBI, and none were diagnosed with active TB. All LTBI cases were recommended for anti-tuberculosis prophylaxis and 43 (75.4%) completed treatment. Refugees receiving care from PRHC clinics were more likely to be screened within 30 days of arrival (OR 4.70, 95%CI 2.12-10.44), attend a follow-up appointment (OR 4.53, 95%CI 1.36-16.27), and complete treatment (OR 9.44, 95%CI 2.39-37.3). CONCLUSION Refugees who attended PRHC clinics were more likely to be evaluated promptly and to complete LTBI treatment. The PRHC clinics serve as a model for communities seeking to improve refugee health care.

BackgroundThe aim of this study was to investigate the impact of Mental Health First Aid (MHFA) training for Bhutanese refugee community leaders in the U.S. We hypothesized that training refugee leaders would improve knowledge of mental health problems and treatment process and decrease negative attitudes towards people with mental illness.MethodsOne hundred and twenty community leaders participated in MHFA training, of whom 58 had sufficient English proficiency to complete pre- and post-tests. The questionnaires assessed each participants ability to recognize signs of depression, knowledge about professional help and treatment, and attitudes towards people with mental illness.ResultsBetween the pre- and post-test, participants showed significant improvement in the recognition of symptoms of depression and expressed beliefs about treatment that became more concordant with those of mental health professionals. However, there was no reduction in negative attitudes towards people with mental illness.ConclusionsMHFA training course is a promising program for Bhutanese refugee communities in the U.S. However, some adaptations may be necessary to ensure that MHFA training is optimized for this community.

Our objective was to examine refugees’ acute care use early in resettlement. We conducted a retrospective cohort study of acute care use, emergency room and hospital visits, by adult refugees arriving in Southern Connecticut between 2/1/2013 and 2/1/2015. We examined associations between any acute care use and collected demographic as well as health characteristics. Of the 248 refugees in our sample, 57% had a medical evaluation within 30 days of arrival. 102 (41%) had at least one acute care visit within 8 months of arrival. Male sex (OR 1.90, 95% CI 1.09–3.30) and prior history of hypertension (OR 2.87, 95% CI 1.06–7.33) were associated with greater likelihood of an acute care visit within 8 months of arrival, while having a medical evaluation within 30 days of arrival was associated with lower likelihood (OR 0.56, 95% CI 0.32–0.98). Designing systems to ensure timely evaluations of newly arrived refugees may reduce frequent acute care utilization.
