Children's environmental health and disaster resilience in Puerto Rico and the U.S. Virgin Islands.

The environment plays a significant role in the global burden of disease for children. Climate-related disasters such as the 2017 Atlantic hurricane season are increasingly contributing to this burden. United Nations designated Small Island Developing States (SIDS) like Puerto Rico and the U.S. Virgin Islands are particularly at risk due to environmental health hazards caused by natural disasters, and health care structure vulnerabilities. United Nations' Sustainable Development Goals (UN SDG), specifically UN SDG 3, 13 and 17, focus on climate impacts via promotion of health preparedness and building partnerships between different sectors of society, respectively. The Pediatric Environmental Health Specialty Unit's (PEHSU) work is consistent with these most notably via the delivery of environmental health services along with training nurses, doctors, and other health professionals, formation of partnerships and linking resources. Therefore, training a diverse array of health professionals and linking these groups to relevant community resources is of utmost importance and has the potential to enhance the effective management and early prevention of top environmental health (EH) risks. Nursing is identified as a key health sector to engage for this initiative. This article describes the work of the Federal Region 2 PEHSU in Puerto Rico and the U.S. Virgin Islands that supports health professionals' knowledge building, development of environmental health services, and promotion of wide scale access to such services for children and families. The PEHSU's work is consistent with these most notably with regards to the delivery of environmental health services in pediatrics.

Co-exposure to manganese and lead and pediatric neurocognition in East Liverpool, Ohio.

Exposure to metal mixtures may lead to health impacts greater than the effects associated with singular exposures. Two common childhood environmental exposures, manganese (Mn) and lead (Pb), are associated with similar adverse neurodevelopmental effects; however, the effects surrounding concurrent exposure to both metals remain unclear. We study the impact of joint exposure to Mn and Pb on cognitive performance in school-aged children participating in the Communities Actively Researching Exposure Study (CARES) based in East Liverpool, Ohio. Blood Pb levels were measured for each child (geometric mean (GM) = 1.13 µg/dL, range 0.30 µg/dL - 6.64 µg/dL). Mn was measured in participant blood, hair, and toenails with GMs of 10.1 µg/L, 360 ng/g, 0.974 µg/g, respectively. Trained team members administered the Wechsler Intelligence Scale for Children-IV (WISC-IV) to assess intelligence quotient (IQ). The WISC-IV provides scores for Full Scale IQ, Perceptual Reasoning, Processing Speed, Working Memory, and Verbal Comprehension. Interactions between blood Pb and all Mn biomarkers were tested in linear models adjusted for child sex, household income, and serum cotinine. Separate regression models were run for each of the Mn biomarkers. The cohort was comprised of 106 children with a mean age of 8.4 years. Interactions between blood Pb and hair Mn were significant (p < 0.05) for four out of the five IQ domains. The effect of blood Pb on IQ was more pronounced at higher levels of hair and toenail Mn. No significant associations were observed when characterizing the main effect of Mn using blood. Uncovering the health impacts associated with exposure mixtures is critical to understanding the impact of real-life conditions. Our findings suggest that joint exposure to Mn and Pb may produce heightened neurocognitive impacts even at blood Pb levels below the CDC reference concentration of 5 µg/dL.

Developing and implementing core competencies in children's environmental health for students, trainees and healthcare providers: a narrative review.

Knowledge of the health impacts of environmental exposures (such as pollution disasters, poor air quality, water contamination, climate change) on children's health has dramatically increased in the past 40 years. The World Health Organization (WHO) estimated that 23% of all deaths worldwide were attributable to the environment, and 26% of deaths in children less than 5 years old could be prevented with removal of environmental risks factors. Yet, little has permeated medical education, leaving pediatric providers ill equipped to address these issues. To address this gap, members from the Pediatric Environmental Health Specialty Units, a United States nationwide network of academically affiliated experts who have created numerous environmental health educational materials and programs, have identified fifteen core environmental health (EH) competencies needed by health care providers to enable them to effectively address environmental health concerns. These competencies can serve as the foundation for the development and implementation of relevant educational programs. The core EH competencies are based upon these foundational elements: 1) Definition of "children's environmental health" that describes how environmental exposures (positive and negative) in early life influence the health and development in childhood and across the entire human life span 2) Children are not "little adults" and so have unique vulnerabilities to environmental hazards; 3) Environmental health inequities exist, causing some children to have a disproportionate amount of unhealthy exposures and consequently a greater risk of adverse effects; 4) Climate change will translate to numerous adverse health effects that will particularly affect children worldwide. In this article, the authors describe the core environmental health competencies and provide resources, online tools, strategies, and examples targeted to all levels of training and practice to better enable leaders and educators to bring this important content to the forefront.

Media Coverage of Pediatric Environmental Health Risks and its Effects on Mothers' Protective Behaviors.

This study explores the relationship between exposure to U.S. media coverage of chemical threats to pediatric environmental health and mothers' behaviors to protect their children. Prior content analytic work revealed that media coverage volume from September 2012 to February 2013 differed significantly by type of chemical (i.e., pesticides = high coverage volume; bisphenol A [BPA] = moderate; and arsenic = low). Survey data collected from new and expecting mothers in March 2013 (n = 822) revealed mothers incidentally encountered-or scanned-this information in the media in the prior six months, and after adjusting for a series of potential confounders, such scanning was positively associated with mothers' self-reported behaviors to reduce chemical exposures. To test the hypothesis that coverage volume moderates the relationship between scanning and behavior, content analysis and survey data were combined in mixed effects regression analyses. Results showed significant differences between the effects of media scanning at different levels of coverage volume, but in a direction not entirely consistent with the study's hypothesis. The relationship between scanning and behavior was strongest for BPA, suggesting that a characteristic of media coverage other than volume may drive maternal responses to environmental health threats. Implications of these findings for risk communication research and practice are discussed.

Epigenome-wide association study of fluoride exposure during early adolescence and DNA methylation among U.S. children.

Exposure to fluoride in early childhood has been associated with altered cognition, intelligence, attention, and neurobehavior. Fluoride-related neurodevelopment effects have been shown to vary by sex and very little is known about the mechanistic processes involved. There is limited research on how fluoride exposure impacts the epigenome, potentially leading to changes in DNA methylation of specific genes regulating key developmental processes. In the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS), urine samples were analyzed using a microdiffusion method to determine childhood urinary fluoride adjusted for specific gravity (CUFsg) concentrations. Whole blood DNA methylation was assessed using the Infinium MethylationEPIC BeadChip 850 k Array. In a cross-sectional analysis, we interrogated epigenome-wide DNA methylation at 775,141 CpG loci across the methylome in relation to CUFsg concentrations in 272 early adolescents at age 12 years. Among all participants, higher concentrations of CUF were associated with differential methylation of one CpG (p < 6 × 10-8) located in the gene body of GBF1 (cg25435255). Among females, higher concentrations of CUFsg were associated with differential methylation of 7 CpGs; only three CpGs were differentially methylated among males with no overlap of significant CpGs observed among females. Secondary analyses revealed several differentially methylated regions (DMRs) and CpG loci mapping to genes with key roles in psychiatric outcomes, social interaction, and cognition, as well as immunologic and metabolic phenotypes. While fluoride exposure may impact the epigenome during early adolescence, the functional consequences of these changes are unclear warranting further investigation.

An Update on Pediatric Environmental Health Specialty Units: Activities and Impacts, 2015-19.

OBJECTIVE: Pediatric Environmental Health Specialty Units (PEHSUs) address health concerns impacting children and their families related to environmental hazards by providing consultation and education to families, communities, and health care professionals. This analysis evaluated the productivity of the national PEHSU program. METHODS: PEHSUs reported data on services provided to US communities between October 1, 2014 and September 30, 2019. Descriptive statistics and qualitative analysis are presented. RESULTS: During this period, 6102 consultations and 4644 educational outreach activities were recorded. PEHSU faculty and staff published 462 articles, reviews, book chapters, fact sheets, commentaries, short informational pieces, and other materials between 2014 and 2019. These included 190 articles in scientific peer-reviewed journals and 29 textbook chapters to increase professional capacity in pediatric and reproductive environmental health. Lead, other metals, substances of abuse, pesticides, mold, and air pollution were frequently reported as agents of concern and educational topics. Requests for an overview of pediatric environmental health and outdoor pollutants were other frequently reported topics. CONCLUSIONS: PEHSUs work to decrease harmful exposures and improve children's health. They serve as expert resources for families, health care professionals, and communities on health effects related to environmental exposures. Data show the breadth and depth of concerns addressed and demonstrate the productivity and impact of this national program.

Evaluating Effectiveness of Online Learning Modules in Pediatric Environmental Health Education.

OBJECTIVE: Content and training about pediatric environmental health are lacking in healthcare professionals' education. In an initiative to improve pediatric environmental health education, the Pediatric Environmental Health Specialty Unit (PEHSU) program offers free, interactive, web-based ("eLearning") modules on environmental health topics. The aim of this study is to determine the effectiveness of PEHSU eLearning modules in increasing knowledge about pediatric and reproductive environmental health. METHODS: This is a retrospective analysis of 994 users who had completed at least one of the 12 PEHSU eLearning modules and its associated pre-test and post-test scores between March 2016 and November 2018. Users who completed modules between March 2016 and April 2018 received a 6-month follow-up survey to assess the impact of the knowledge gained on their clinical practice. RESULTS: A wide range of clinical professionals and nonclinical professionals utilized and completed the PEHSU eLearning modules. For all users, post-test scores were significantly higher than pre-test scores, with an increase of 30.55% ± 22.37 (paired t-test, p < 0.0001), after completion of eLearning modules. CONCLUSION: PEHSU eLearning modules are effective at increasing environmental health knowledge of clinical and nonclinical professionals. Further studies are needed to determine long-term knowledge retention and clinical impact.

Private well water testing promotion in pediatric preventive care: A randomized intervention study.

Over 43 million U.S. residents rely on private unregulated wells for their drinking water, raising public health concerns, particularly in regions like northern New England where widespread groundwater arsenic contamination is now recognized. Children are particularly vulnerable to adverse health effects from arsenic exposure. Despite AAP Guidelines, approaches to engage pediatric clinicians in promoting private well testing have not been previously described. We sought to determine the most effective practice approaches to achieve successful well water testing in routine pediatric care. 12 primary care clinics were block randomized to one of four study arms. Two intervention variables were assessed: (1) test results access (parent only vs. parent and clinic) and (2) follow up approaches (yes/no). Parents of children under 12 months using a private well were eligible. Prepaid water tests were provided. Primary outcome was parental water test completion. Eleven clinics successfully implemented processes identifying well users. 240 testing kits were dispensed. Completion rates averaged 29% (range 10 to 61%). The study arm with both clinic results access and staff follow up system was 2.3 times more likely to achieve test completion than other arms (95% CI 1.12-4.86, p = .03). Kit distribution by clinicians versus nursing staff, irrespective of study arm, had 2.4 times greater completion (95% CI 1.13-5.11, p = .02). Systematic drinking water source screening can be improved in pediatric care. Higher testing completion was found in practices randomized to reminders and structured follow up versus single visit discussion, but clinician involvement was the most predictive factor.

Pediatric Environmental Health Specialty Units: An Analysis of Operations.

BACKGROUND: In 1998 the Agency for Toxic Substances and Disease Registry (ATSDR) secured the first federal funding to develop an innovative network of public health-oriented entities: Pediatric Environmental Health Specialty Units (PEHSUs). PEHSU goals were to provide pediatric and environmental health education to health care providers and health profession students, to offer consultation to health care professionals, parents, and others regarding environmental health exposures, and to provide referrals to specialized medical resources when necessary. This report analyzes the productivity of US PEHSUs from 1999 to 2014. METHODS: This was a retrospective analysis of federally mandated quarterly reports filed by each PEHSU. These reports document specific goal-related deliverables outlined under cooperative agreements awarded to the Association of Occupational and Environmental Clinics (AOEC) with funding from the Environmental Protection Agency (EPA) and ATSDR. Costs were obtained from grant budget information available from the administrator of the grants, AOEC. RESULTS: Total EPA/ATSDR funding for PEHSUs paid to AOEC during 1999-2014 was $23,847,452. The average cost to the EPA/ATSDR of running each PEHSU in 2014 was $169,256. Through over 8000 consultations and educational activities, PEHSUs reached 702,506 people: 298,936 health professionals, 61,947 health professional trainees, 323,817 members of the public, and 17,806 public health officials and others. CONCLUSIONS: PEHSUs have grown into an established, productive network of clinical and educational centers whose expertise and activities have benefited both the public and health care professionals alike. The federal contributions to the cost of operating these centers have been more than offset by the benefits PEHSUs have conferred on the communities they serve.

Children's Environmental Health: A Brief History.

BACKGROUND: Children's environmental health (CEH), the branch of pediatrics that studies the influence of the environment on children's health, has grown substantially in the past 3 decades and become an increasingly visible and important component of pediatric medicine. GOALS: To trace the historical origins of CEH; to identify factors responsible for its recent growth. FINDINGS: CEH has historical roots in toxicology, epidemiology, and occupational medicine. It arose in the second half of the 20th century through a melding of insights from pediatric toxicology, nutritional epidemiology, and social science research. Convergent research in these 3 fields has documented children's unique sensitivities to chemical, nutritional, and psychosocial hazards during windows of vulnerability in early development and has shown that early-life exposures can produce disease and disability in childhood and across the life span. Key events in the development of CEH were: 1) formation by the American Academy of Pediatrics in 1957 of a committee on environmental health that has nurtured the growth of the field for 5 decades and evolved into the Council on Environmental Health; 2) observations made in the 1980s that nutritional deficiency in utero increased risk for adult-onset obesity, diabetes, and cardiovascular disease-work that led to the hypothesis of the developmental origins of health and disease; 3) social science research showing that early exposure to psychosocial stress and trauma increases risk for chronic illness; and 4) publication in 1993 by the National Academy of Sciences of a report, Pesticides in the Diets of Infants and Children, which elevated awareness among national policy makers of children's vulnerability to toxic hazards, moved US environmental policy toward protection of children's health, and catalyzed research investment in CEH in the United States and globally. CONCLUSIONS: CEH has made substantial progress but faces emerging challenges, including new chemicals and pesticides; increasing movement of polluting industries to poor countries where environmental and public health protections are few; and global climate change. In the future, CEH will require continued investment in research and education and will need to adopt an increasingly global perspective.
