Evaluating e-Connect: Mitigating Race by Gender Disparities in Behavioral Health Referral Among Youths on Probation, Northeast United States, 2019.

Addressing the behavioral health needs of youths involved in the justice system is key to reducing recidivism risk and preventing long-term system involvement. However, rates of treatment referral and initiation remain low, especially among minoritized youths and boys. The e-Connect System, a digital, clinical decision support system, addresses this problem by increasing rates of behavioral health treatment referral and initiation rates among youths on probation. In this study, we examine whether e-Connect helps improve equity in referral and treatment initiation outcomes.

E-Connect: Linking probation youth at risk for suicide to behavioral health services.

OBJECTIVE: Youth involved in the justice system (YIJ) have higher rates of suicidal thoughts and behaviors (STB) and associated behavioral health (BH) problems, yet lower levels of service use compared to youth in the general population. This study examined the efficacy of e-Connect, a digital clinical decision support system (CDSS), at improving STB risk identification, referral, and linkage to BH services by probation officers. As the intervention spanned pre- and post-COVID-19 shutdown periods, we also examined the disruption in public agencies' service provision on study outcomes. METHOD: Administrative record data (1,488 youth, ages 10-18 years, 56% male, 56% White) allowed examination of differences between care-as-usual (baseline) and e-Connect in screening, identification of STB and BH problems, referral, and treatment initiation. RESULTS: Compared to care-as-usual, probation officers using e-Connect were over five times as likely to identify YIJ with STB (adjusted odds ratio [aOR] = 5.86; 95% confidence interval, CI [3.24, 11.7]) and over 11 times more likely to refer YIJ in need of BH services to treatment (aOR = 11.04; 95% CI [6.54, 19.43]). In turn, youth referred to treatment via e-Connect were nearly 17 times more likely to initiate (aOR = 16.92; 95% CI [9.17, 32.60]). Results remained unchanged during the pre- and post-COVID-19 shutdown periods. CONCLUSION: e-Connect is one of the first digital STB screening, referral, and linkage-to-service systems that use CDSS technology to successfully assist probation officers in linking youth on their caseload to treatment. Such an approach may support identification of STB and cross-systems linkage in other youth-serving organizations, such as schools, that increasingly manage youth BH problems with minimal clinical support.

The comparative effectiveness of Core versus Core+Enhanced implementation strategies in a randomized controlled trial to improve substance use treatment receipt among justice-involved youth.

BACKGROUND: Most justice-involved youth are supervised in community settings, where assessment and linkage to substance use (SU) treatment services are inconsistent and fragmented. Only 1/3 of youth with an identified SU need receive a treatment referral and even fewer initiate services. Thus, improving identification and linkage to treatment requires coordination across juvenile justice (JJ) and behavioral health (BH) agencies. The current study examines the comparative effectiveness of two bundled implementation intervention strategies for improving SU treatment initiation, engagement, and continuing care among justice-involved youth supervised in community settings. Exploration, Preparation, Implementation, Sustainment (EPIS) served as the conceptual framework for study design and selection/timing of implementation intervention components, and the BH Services Cascade served as the conceptual and measurement framework for identifying and addressing gaps in service receipt. METHODS: Part of a larger Juvenile-Justice Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) Cooperative, this study involved a multisite, cluster-randomized control trial where sites were paired then randomly assigned to receive Core (training teams on the BH Services Cascade and data-driven decision making; supporting goal selection) or Core+Enhanced (external facilitation of implementation teams) intervention components. Youth service records were collected from 20 JJ community supervision agencies (in five states) across five study phases (baseline, pre-randomization, early experiment, late experiment, maintenance). Implementation teams comprised of JJ and BH staff collaboratively identified goals along the BH Cascade and used data-driven decision-making to implement change. RESULTS: Results suggest that Core intervention components were effective at increasing service receipt over time relative to baseline, but differences between Core and Core+Enhanced conditions were non-significant. Time to service initiation was shorter among Core+Enhanced sites, and deeper Cascade penetration occurred when external facilitation (of implementation teams) was provided. Wide variation existed in the degree and nature of change across service systems. CONCLUSIONS: Findings demonstrate the criticality of early EPIS phases, demonstrating that strategies provided during the formative exploration and preparation phases produced some improvement in service receipt, whereas implementation-focused activities produced incremental improvement in moving youth farther along the Cascade.

Using structured implementation interventions to improve referral to substance use treatment among justice-involved youth: Findings from a multisite cluster randomized trial.

INTRODUCTION: Youth involved in the justice system have high rates of alcohol and other drug use, but limited treatment engagement. JJ-TRIALS tested implementation activities with community supervision (CS) and behavioral health (BH) agencies to improve screening, identification of substance use service need, referral, and treatment initiation and engagement, guided by the BH Services Cascade and EPIS frameworks. This paper summarizes intervention impacts on referrals to treatment among youth on CS. METHODS: This multisite cluster-randomized trial involved 18 matched pairs of sites in 36 counties in seven states randomly assigned to core or enhanced conditions after implementing the core intervention at all sites for six months. Enhanced sites received external facilitation for local change team activities to reduce unmet treatment needs; Core sites were encouraged to form interagency workgroups. The dependent variable was percentage referred to treatment among youth in need (N = 14,012). Two-level Bayesian regression assessed factors predicting referral across all sites and time periods. Generalized linear mixed models using logit transformation tested two hypotheses: (H1) referrals will increase from baseline to the experimental period, (H2) referral increases will be larger in enhanced sites than in core sites. RESULTS: Although the intervention significantly increased referral, condition did not significantly predict referral across all time periods. Youth who tested drug positive, had an alcohol/other drug-related or felony charge, were placed in secure detention or assigned more intensive supervision, or who were White were more likely to be referred. H1 (p < .05) and H2 (p < .0001) were both significant in the hypothesized direction. Interaction analyses comparing site pair differences showed that findings were not consistent across sites. CONCLUSIONS: The percentage of youth referred to treatment increased compared with baseline overall, and enhanced sites showed larger increases in referrals over time. However, variations in effects suggest that site-level differences were important. Researchers should carry out mixed methods studies to further understand reasons for the inconsistent findings within randomized site pairs, and how to further improve treatment referrals across CS and BH systems. Findings also highlight that even when CS agencies work collaboratively with BH providers to improve referrals, most justice-involved youth who need SU services are not referred.

Mixed metals exposure and cognitive function in Bangladeshi adolescents.

BACKGROUND: Over 57 million people in Bangladesh have been chronically exposed to arsenic-contaminated drinking water. They also face environmental exposure to elevated levels of cadmium (Cd), manganese (Mn), and lead (Pb), all of which have been previously observed in environmental and biological samples for this population. These metals have been linked to adverse neurocognitive outcomes in adults and children, though their effects on adolescents are not yet fully characterized. Additionally, previous studies have linked selenium (Se) to protective effects against the toxicity of these other metals. OBJECTIVES: To examine the associations between mixed metals exposure and cognitive function in Bangladeshi adolescents. METHODS: The Metals, Arsenic, & Nutrition in Adolescents study (MANAs) is a cross-sectional study of 572 Bangladeshi adolescents aged 14-16 years, whose parents were enrolled in the Health Effects of Arsenic Longitudinal Study (HEALS). Biosamples were collected from these adolescents for measurement of whole blood metalloid/metal levels of As, Cd, Mn, Pb, and Se. Participants also completed an abbreviated version of The Cambridge Neuropsychological Test Automated Battery (CANTAB), a cognitive function test designed to measure performance across several aspects of executive function. Linear regression was used to examine associations for each metal while controlling for the other metals. Bayesian Kernel Machine Regression (BKMR) assessed the overall mixture effect in addition to confirming the effects of individual metal components observed via linear regression. RESULTS: Linear regression revealed negative associations for Spatial Working Memory and both As and Mn (As B=-2.40, Mn B=-5.31, p < 0.05). We also observed negative associations between Cd and Spatial Recognition Memory (B=-2.77, p < 0.05), and Pb and Delayed Match to Sample, a measure of visual recognition and memory (B=-3.67, p < 0.05). Finally, we saw a positive association for Se and Spatial Span Length (B=0.92, p < 0.05). BKMR results were largely consistent with the regression analysis, showing meaningful associations for individual metals and CANTAB subtests, but no overall mixture effect. Via BKMR, we observed negative associations between Pb and Delayed Match to Sample, and Cd and Spatial Recognition Memory; this analysis also showed positive associations for Se and the Planning, Reaction Time, and Spatial Span subtests. BKMR posterior inclusion probability consistently reported that Se, the only component of the mixture to show a positive association with cognition, was the most important member of the mixture. CONCLUSIONS: Overall, we found Se to be positively associated with cognition, while Mn and As were linked to poorer working memory, and Cd and Pb were associated with poorer visual recognition and memory. Our observations are consistent with previous reports on the effects of these metal exposures in adults and children. Our findings also suggest agreement between linear regression and BKMR methods for analyzing metal mixture exposures. Additional studies are needed to evaluate the impact of mixed metals exposure on adverse health and poorer cognition later in life for those exposed during adolescence. Findings also suggest that metal exposure mitigation efforts aimed at adolescents might influence lifelong cognitive outcomes in regions where environmental exposure to metals is endemic.

Bridging juvenile justice and behavioral health systems: development of a clinical pathways approach to connect youth at risk for suicidal behavior to care.

BACKGROUND: Justice-involved youth have high rates of suicidal behavior and co-morbid psychiatric disorders, yet low rates of service use. Implementation efforts aimed at supporting cross-agency linkage protocols may be useful components of interventions promoting behavioral healthcare service access for youths on probation. The purpose of this study was to develop clear referral Pathways for three suicide risk classifications of youth, across 10 counties in a single state through a community-academic partnership in New York state, a strategic planning process between county Probation departments and community Behavioral Health. RESULTS: We sought to clarify service destinations for youth in three classes of risk for suicidal behavior: Class I (Crisis, Imminent Risk); Class II (Crisis, Non-Imminent Risk); and Class III (Non-Crisis but in Need of Service). Prior to Pathway Meetings, there was a low degree of agreement between Probation and Behavioral Health leadership for the appropriate service destination for youths in crisis, whether at imminent risk (Class I: 57.8% overlap) or at lower than imminent risk (Class II: 45.6% overlap). Options for referral destinations for Classes I and II decreased significantly (indicating greater overlap) as a result of Pathway Meetings [(Class I: from 2.5 to 1.1 (t(9) = 3.28, p < 0.01); Class II: from 2.8 to 1.3 (t(9) = 4.025, p < 0.003)]. Pathway Meetings allowed Behavioral Health and Juvenile Justice systems to make joint decisions regarding referral pathways, resulting in innovative solutions, such as the use of mobile crisis. CONCLUSIONS: The community-academic partnership served to bring internal (Juvenile Justice) and external (Behavioral Health) contexts together to successfully generate agreed upon Pathways to care for youths demonstrating risk for suicidal behavior. Bridging Behavioral Health and Juvenile Justice systems together to agree to referral Pathways for each risk class can increase appropriate service use.

The Missing Link(age): Multilevel Contributors to Service Uptake Failure Among Youths on Community Justice Supervision.

OBJECTIVES: Youths in the juvenile justice system often do not access needed behavioral health services. The behavioral health services cascade model was used to examine rates of substance use screening, identification of substance use treatment needs, and referral to and initiation of treatment among youths undergoing juvenile justice system intake and to identify when treatment access is most challenged. Characteristics associated with identification of behavioral health needs and linkage to community services were also examined. METHODS: Data were drawn from administrative records of 33 community justice agencies in seven states participating in Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System, funded by the National Institute on Drug Abuse (N=8,307 youths). Contributions of youth, staff, agency, and county characteristics to identification of behavioral health needs and linkage to community services were examined. RESULTS: More than 70% (5,942 of 8,307) of youths were screened for substance use problems, and more than half needed treatment. Among those in need, only about one-fifth were referred to treatment, and among those referred, 67.5% initiated treatment. Overall, <10% of youths with identified needs initiated services. Multivariable multilevel regression analyses revealed several contributors to service-related outcomes, with youths' level of supervision being among the strongest predictors of treatment referral. CONCLUSIONS: Community justice agencies appear to follow an approach that focuses identification and linkage practices on concerns other than youths' behavioral health needs, although such needs contribute to reoffending. Local agencies should coordinate efforts to support interagency communication in the referral and cross-system linkage process.

Falling between two systems of care: Engaging families, behavioral health and the justice systems to increase uptake of substance use treatment in youth on probation.

Justice-involved youth (JIY) in the US have high rates of substance use (SU) problems, yet 50%-80% of these youth do not receive necessary services. There has been no systematic exploration of the use of treatment services for JIY that examines viewpoints across stakeholders in justice- and treatment-systems as well as the families. We conducted qualitative interviews and focus groups with n = 58, youth, their caregivers, SU treatment providers and probation officers in a Northeastern state. Interviews explored how families, staff- and system-level factors influence uptake of and retention in SU treatment services in youth on probation. We conducted a thematic analysis of all interview texts. Caregiver engagement is essential for youth treatment uptake and retention. Difficulties achieving caregiver engagement and agreement that treatment was necessary stemmed from distrust in the "system"; denial or minimization of youth's SU problem; relational barriers; and overburden and chaos within the family system. Structural barriers to service uptake were lack of available treatment options, SU agency practices and policies, and interagency collaboration between SU treatment agencies and probation. Enhancing family engagement at the point of referral to SU treatment is essential. Improvements in interagency collaboration and communication between SU treatment and probation agencies are necessary. Implications for policy and intervention are discussed.

Early life and adolescent arsenic exposure from drinking water and blood pressure in adolescence.

OBJECTIVES: Evidence of the association between inorganic arsenic (As) exposure, especially early-life exposure, and blood pressure (BP) in adolescence is limited. We examined the association of As exposure during early childhood, childhood, and adolescence with BP in adolescence. METHODS: We conducted a cross-sectional study of 726 adolescents aged 14-17 (mean 14.75) years whose mothers were participants in the Bangladesh Health Effects of Arsenic Longitudinal Study (HEALS). Adolescents' BP was measured at the time of their recruitment between December 2012 and December 2016. We considered maternal urinary As (UAs), repeatedly measured during childhood, as proxy measures of early childhood (<5 years old, A1) and childhood (5-12 years old, A2) exposure. Adolescents' current UAs was collected at the time of recruitment (14-17 years of age, A3). RESULTS: Every doubling of UAs at A3 and maternal UAs at A1 was positively associated with a difference of 0.7-mmHg (95% confidence interval [CI]: 0.1, 1.3) and a 0.7-mmHg (95% CI: 0.05, 1.4) in SBP, respectively. These associations were stronger in adolescents with a BMI above the median (17.7 kg/m2) than those with a BMI below the median (P for interaction = 0.03 and 0.03, respectively). There was no significant association between any of the exposure measures and DBP. The Weighted Quantile Sum (WQS) regression confirmed that adolescents' UAs at A3 and maternal UAs at A1 contributed the most to the overall effect of As exposure at three life stages on SBP. Mixture analyses using Bayesian Kernel Machine Regression identified UAs at A3 as a significant contributor to SBP and DBP independent of other concurrent blood levels of cadmium, lead, manganese, and selenium. CONCLUSION: Our findings suggest an association of current exposure and early childhood exposure to As with higher BP in adolescents, which may be exacerbated by higher BMI at adolescence.

Organizational Context and Individual Adaptability in Promoting Perceived Importance and Use of Best Practices for Substance Use.

This study examines associations among organizational context, staff attributes, perceived importance, and use of best practices among staff in community-based, juvenile justice (JJ) agencies. As part of the National Institute on Drug Abuse's Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) study, 492 staff from 36 JJ agencies were surveyed about the perceived importance and use of best practices within their organization in five substance use practice domains: screening, assessment, standard referral, active referral, and treatment support. Structural equation models indicated that supervisory encouragement and organizational innovation/flexibility were associated with greater individual adaptability. Adaptability (willingness to try new ideas, use new procedures, adjust quickly to change), was positively correlated with importance ratings. Importance ratings were positively associated with reported use of best practices. Organizational climates that support innovation likely affect use of practices through staff attributes and perceptions of the importance of such services.

Disruptive Mood Dysregulation Disorder in Juvenile Justice.

Disruptive mood dysregulation disorder (DMDD) is a new diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). We compared juvenile justice involved youths with DMDD to those with disruptive behavior disorders (DBDs) and other mood disorders, to clarify the differences and to investigate differential correlates to DMDD relative to DBDs or mood disorders. Diagnostic and demographic data were available for 9,819 youths served by 57 juvenile justice sites. A subsample of 2,498 youths had data relevant to our study. The youths self-assessed mental health status on the Voice Diagnostic Interview Schedule for Children (V-DISC), and we retrofitted the V-DISC data to derive an approximate DMDD diagnosis. The retrofitted criteria for DMDD were met by 3.3 percent of justice-involved youths. Results from multinomial regression showed that, after adjustment for covariates, those with DMDD had fewer differences compared with those with other mood disorders than did those meeting criteria for DBDs. Consistent with the DSM-5 classification of DMDD as a depressive disorder, those with DMDD shared more characteristics with youths with mood disorders than with those reporting DBDs. Externalizing behaviors leading to justice involvement may overshadow internalizing symptoms of DMDD, but mood-related conditions should be identified and treated in this population.

A cross-sectional study of water arsenic exposure and intellectual function in adolescence in Araihazar, Bangladesh.

BACKGROUND: Exposure to inorganic arsenic (As) from drinking water is associated with modest deficits in intellectual function in young children; it is unclear whether deficits occur during adolescence, when key brain functions are more fully developed. OBJECTIVES: We sought to determine the degree to which As exposure is associated with adolescent intelligence, and the contributory roles of lead, cadmium, manganese and selenium. METHODS: We recruited a cross-section of 726 14-16 year olds (mean age = 14.8 years) whose mothers are participants in the Bangladesh Health Effects of Arsenic Longitudinal Study (HEALS), and whose household well water As levels, which varied widely, were well characterized. Using a culturally modified version of the WISC-IV, we examined raw Full Scale scores, and Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed Indices. Blood levels of As (BAs), Mn, Pb, Cd and Se were assessed at the time of the visit, as was creatinine-adjusted urinary As (UAs/Cr). RESULTS: Linear regression analyses revealed that BAs was significantly negatively associated with all WISC-IV scores except for Perceptual Reasoning. With UAs/Cr as the exposure variable, we observed significantly negative associations for all WISC-IV scores. Except for Se, blood levels of other metals, were also associated with lower WISC-IV scores. Controlling for covariates, doubling BAs, or UAs/Cr, was associated with a mean decrement (95% CI) of 3.3 (1.1, 5.5), or 3.0 (1.2, 4.5) points, respectively, in raw Full scale scores with a sample mean of 177.6 (SD = 36.8). Confirmatory analyses using Bayesian Kernel Machine Regression, which identifies important mixture members, supported these findings; the primary contributor of the mixture was BAs, followed by BCd. CONCLUSIONS: Our data indicate that the adverse consequences of As exposure on neurodevelopment observed in other cross-sectional studies of younger children are also apparent during adolescence. They also implicate Cd as a neurotoxic element that deserves more attention.

Comparison of the Overlap between Juvenile Justice Processing and Behavioral Health Screening, Assessment and Referral.

Given the large proportion of youth involved in the juvenile justice system who meet criteria for behavioral health disorders, the system is charged with delivering not only criminal justice programing, but also behavioral health services. Behavioral health service delivery is typically done through collaborative partnerships with behavioral health agencies. This study created process maps which describe the flows and boundaries of these partnerships with respect to screening, assessment and referral to treatment. Process maps of juvenile justice and behavioral health systems from six juvenile departments in different states (Mississippi, Kentucky, New York, Georgia, Texas, and Pennsylvania) are presented. Both the methodology of creating process maps and results from the analysis of the maps are presented. Results indicate that behavioral health screening, assessment, and referral to treatment were occurring at all sites, typically with standardized tools. Overall trends were that juveniles tended to have more screenings, assessments, and referrals to behavioral health services as they moved deeper into the juvenile justice system and were placed into more formal juvenile justice services. Within the analysis of interagency communication, these results were mirrored; settings that were more formal and located deeper into the juvenile justice system had more robust interagency communication.

The Juvenile Justice Behavioral Health Services Cascade: A new framework for measuring unmet substance use treatment services needs among adolescent offenders.

OVERVIEW: Substance use and substance use disorders are highly prevalent among youth under juvenile justice (JJ) supervision, and related to delinquency, psychopathology, social problems, risky sex and sexually transmitted infections, and health problems. However, numerous gaps exist in the identification of behavioral health (BH) problems and in the subsequent referral, initiation and retention in treatment for youth in community justice settings. This reflects both organizational and systems factors, including coordination between justice and BH agencies. METHODS AND RESULTS: This paper presents a new framework, the Juvenile Justice Behavioral Health Services Cascade ("Cascade"), for measuring unmet substance use treatment needs to illustrate how the cascade approach can be useful in understanding service delivery issues and identifying strategies to improve treatment engagement and outcomes for youth under community JJ supervision. We discuss the organizational and systems barriers for linking delinquent youth to BH services, and explain how the Cascade can help understand and address these barriers. We provide a detailed description of the sequential steps and measures of the Cascade, and then offer an example of its application from the Juvenile Justice - Translational Research on Interventions for Adolescents in the Legal System project (JJ-TRIALS), a multi-site research cooperative funded by the National Institute on Drug Abuse. CONCLUSION: As illustrated with substance abuse treatment, the Cascade has potential for informing and guiding efforts to improve behavioral health service linkages for adolescent offenders, developing and testing interventions and policies to improve interagency and cross-systems coordination, and informing the development of measures and interventions for improving the implementation of treatment in complex multisystem service settings.

Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS): a cluster randomized trial targeting system-wide improvement in substance use services.

BACKGROUND: The purpose of this paper is to describe the Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) study, a cooperative implementation science initiative involving the National Institute on Drug Abuse, six research centers, a coordinating center, and Juvenile Justice Partners representing seven US states. While the pooling of resources across centers enables a robust implementation study design involving 36 juvenile justice agencies and their behavioral health partner agencies, co-producing a study protocol that has potential to advance implementation science, meets the needs of all constituencies (funding agency, researchers, partners, study sites), and can be implemented with fidelity across the cooperative can be challenging. This paper describes (a) the study background and rationale, including the juvenile justice context and best practices for substance use disorders, (b) the selection and use of an implementation science framework to guide study design and inform selection of implementation components, and (c) the specific study design elements, including research questions, implementation interventions, measurement, and analytic plan. METHODS/DESIGN: The JJ-TRIALS primary study uses a head-to-head cluster randomized trial with a phased rollout to evaluate the differential effectiveness of two conditions (Core and Enhanced) in 36 sites located in seven states. A Core strategy for promoting change is compared to an Enhanced strategy that incorporates all core strategies plus active facilitation. Target outcomes include improvements in evidence-based screening, assessment, and linkage to substance use treatment. DISCUSSION: Contributions to implementation science are discussed as well as challenges associated with designing and deploying a complex, collaborative project. TRIAL REGISTRATION: NCT02672150 .

Child Intelligence and Reductions in Water Arsenic and Manganese: A Two-Year Follow-up Study in Bangladesh.

BACKGROUND: Arsenic (As) exposure from drinking water is associated with modest intellectual deficits in childhood. It is not known whether reducing exposure is associated with improved intelligence. OBJECTIVE: We aimed to determine whether reducing As exposure is associated with improved child intellectual outcomes. METHODS: Three hundred three 10-year-old children drinking from household wells with a wide range of As concentrations were enrolled at baseline. In the subsequent year, deep community wells, low in As, were installed in villages of children whose original wells had high water As (WAs ≥ 50 µg/L). For 296 children, intelligence was assessed by WISC-IV (Wechsler Intelligence Scale for Children, 4th ed.), with a version modified for the study population, at baseline and approximately 2 years later; analyses considered standardized scores for both Full Scale IQ and Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed Indices. Creatinine-adjusted urinary arsenic (UAs/Cr), blood As (BAs), and blood manganese (BMn) were assessed at both times. RESULTS: UAs/Cr concentrations declined significantly by follow-up for both the high (≥ 50 µg/L) and low (< 50 µg/L) WAs subgroups. At baseline, adjusting for maternal age and intelligence, plasma ferritin, head circumference, home environment quality, school grade, and BMn, UAs/Cr was significantly negatively associated with Full Scale IQ, and with all Index scores (except Processing Speed). After adjustment for baseline Working Memory scores and school grade, each 100-µg/g reduction in UAs/Cr from baseline to follow-up was associated with a 0.91 point increase in Working Memory (95% CI: 0.14, 1.67). The change in UAs/Cr across follow-up was not significantly associated with changes in Full Scale IQ or Index scores. CONCLUSIONS: Installation of deep, low-As community wells lowered UAs, BAs, and BMn. A greater decrease in UAs/Cr was associated with greater improvements in Working Memory scores, but not with a greater improvement in Full Scale IQ.

Evaluation of an Elementary School-based Educational Intervention for Reducing Arsenic Exposure in Bangladesh.

BACKGROUND: Chronic exposure to well water arsenic (As) remains a major rural health challenge in Bangladesh and some other developing countries. Many mitigation programs have been implemented to reduce As exposure, although evaluation studies for these efforts are rare in the literature. OBJECTIVES: In this study we estimated associations between a school-based intervention and various outcome measures of As mitigation. METHODS: We recruited 840 children from 14 elementary schools in Araihazar, Bangladesh. Teachers from 7 schools were trained on an As education curriculum, whereas the remaining 7 schools without any training formed the control group. Surveys, knowledge tests, and well-water testing were conducted on 773 children both at baseline and postintervention follow-up. Urine samples were collected from 210 children from 4 intervention schools and the same number of children from 4 control schools. One low-As (< 10 µg/L) community well in each study village was ensured during an 18-month intervention period. RESULTS: After adjustment for the availability of low-As wells and other sociodemographic confounders, children receiving the intervention were five times more likely to switch from high- to low-As wells (p < 0.001). We also observed a significant decline of urinary arsenic (UAs) (p = < 0.001) (estimated ß = -214.9; 95% CI: -301.1, -128.7 µg/g creatinine) among the children who were initially drinking from high-As wells (> Bangladesh standard of 50 µg/L) and significantly improved As knowledge attributable to the intervention after controlling for potential confounders. CONCLUSIONS: These findings offer strong evidence that school-based intervention can effectively reduce As exposure in Bangladesh by motivating teachers, children, and parents.

A cross-sectional study of well water arsenic and child IQ in Maine schoolchildren.

BACKGROUND: In recent studies in Bangladesh and elsewhere, exposure to arsenic (As) via drinking water is negatively associated with performance-related aspects of child intelligence (e.g., Perceptual Reasoning, Working Memory) after adjustment for social factors. Because findings are not easily generalizable to the US, we examine this relation in a US population. METHODS: In 272 children in grades 3-5 from three Maine school districts, we examine associations between drinking water As (WAs) and intelligence (WISC-IV). RESULTS: On average, children had resided in their current home for 7.3 years (approximately 75% of their lives). In unadjusted analyses, household well WAs is associated with decreased scores on most WISC-IV Indices. With adjustment for maternal IQ and education, HOME environment, school district and number of siblings, WAs remains significantly negatively associated with Full Scale IQ and Perceptual Reasoning, Working Memory and Verbal Comprehension scores. Compared to those with WAs < 5 µg/L, exposure to WAs ≥ 5 µg/L was associated with reductions of approximately 5-6 points in both Full Scale IQ (p < 0.01) and most Index scores (Perceptual Reasoning, Working Memory, Verbal Comprehension, all p's < 0.05). Both maternal IQ and education were associated with lower levels of WAs, possibly reflecting behaviors (e.g., water filters, residential choice) limiting exposure. Both WAs and maternal measures were associated with school district. CONCLUSIONS: The magnitude of the association between WAs and child IQ raises the possibility that levels of WAs ≥ 5 µg/L, levels that are not uncommon in the United States, pose a threat to child development.

Service referral for juvenile justice youths: associations with psychiatric disorder and recidivism.

Secondary multiple regression analyses related disorder profile, probation officers' mental health/substance use service referrals, and recidivism in 361 juvenile justice youths. Those with externalizing (disruptive behavior or substance use) disorder or substance offenses were most likely to receive service referrals. Substance disordered youths with service referrals had lower recidivism risk compared to counterparts without referrals; referral lowered the recidivism odds to approximately that for youths without a substance use disorder. Providing juvenile justice youths with systematic mental health assessment and linking those with substance use disorder to mental health and substance use services likely reduces recidivism risk.
