Effect of high dose vitamin D supplementation on subsequent immune responses to administration of the live herpes zoster vaccine to long-term care residents
Levin MJ , Ginde AA , Schmid DS , Lang N , Canniff J , Schwartz RS , Weinberg A . Vaccine 2024 Thirty-three long-term care residents (mean age 76.5 years), who were participating in a study in which they were randomized to receive either oral daily standard dose (400-1000 IU/day) 25-hydroxy vitamin D (vitamin D3) (SD) or high dose (3000-4000 IU/day) (HD) vitamin D3, were vaccinated with the live, attenuated herpes zoster vaccine. Blood was drawn at vaccination and three weeks later to determine varicella-zoster virus (VZV) antibody and T-cell mediated immune responses. ELISA and neutralizing antibodies increased significantly, but to the same extent, in both groups. The antibody avidity significantly increased from pre- to post-vaccination only in the HD group. VZV-CMI, as measured by FLUOROSPOT significantly increased post-vaccination in both groups, but the difference in interferon-γ spot-forming cells (SFC) and interleukin-2 SFC was lower in the HD than SD group. The increase in VZV-CMI correlated inversely with circulating regulatory T cells in the HD group. We conclude that pre-treatment with HD vitamin D3 does not appreciably enhance the antibody response to a live vaccine and that VZV-CMI responses were diminished in HD vitamin D3 recipients. |
Supporting school staff: Insights from employee health and well-being programs
Pitt Barnes S , Lang JE . J Sch Health 2023 93 (9) 842-852 BACKGROUND: The workplace is an important setting for health protection, health promotion, and disease prevention programs. In the school setting, employee health and well-being programs can address many physical and emotional concerns of school staff. This systematic review summarizes evidence-based approaches from employee health and well-being interventions supporting nutrition and physical activity (PA) in a variety of workplace settings. METHODS: The 2-phase systematic review included a search for articles within systematic reviews that met our criteria (addressing employee health and well-being programs; published 2010-2018; Phase 1) and the identification of individual articles from additional searches (addressing school-based employee interventions; published 2010-2020; Phase 2). We included 35 articles. FINDINGS: Across all studies and types of interventions and workplace settings, findings were mixed; however, multicomponent interventions appeared to improve health behaviors and health outcomes among employees. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Schools can apply this evidence from employee health and well-being programs in various workplace settings to implement coordinated and comprehensive employee health and well-being programs. CONCLUSIONS: Employee health and well-being programs may be effective at supporting nutrition and PA. Schools can use findings from employee health and well-being programs in workplaces other than schools to support school staff. |

As part of initial response activities in the United States, enhanced contact investigations were conducted to enable early identification and isolation of additional cases and to learn more about risk factors for transmission.Methods Close contacts of nine early travel-related cases in the United States were identified. Close contacts meeting criteria for active monitoring were followed, and selected individuals were targeted for collection of additional exposure details and respiratory samples. Respiratory samples were tested for SARS-CoV-2 by real-time reverse transcription polymerase chain reaction (RT-PCR) at the Centers for Disease Control and Prevention.Results There were 404 close contacts who underwent active monitoring in the response jurisdictions; 338 had at least basic exposure data, of whom 159 had ≥1 set of respiratory samples collected and tested. Across all known close contacts under monitoring, two additional cases were identified; both secondary cases were in spouses of travel-associated case patients. The secondary attack rate among household members, all of whom had ≥1 respiratory sample tested, was 13% (95% CI: 4 – 38%).Conclusions The enhanced contact tracing investigations undertaken around nine early travel-related cases of COVID-19 in the United States identified two cases of secondary transmission, both spouses. Rapid detection and isolation of the travel-associated case patients, enabled by public awareness of COVID-19 among travelers from China, may have mitigated transmission risk among close contacts of these cases.Competing Interest StatementThe authors have declared no competing interest.Funding StatementNo external funding was sought or received.Author DeclarationsAll relevant ethical guidelines have been followed; any necessary IRB and/or ethics committee approvals have been obtained and details of the IRB/oversight body are included in the manuscript.YesAll necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived.YesI understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov.

Recent O-antigen diversification masks highly pathogenic STEC O104:H4 (preprint)
Lang C , Fruth A , Campbell IW , Jenkins C , Smith P , Strockbine N , Weill FX , Nubel U , Grad YH , Waldor MK , Flieger A . bioRxiv 2022 15 Background: Shiga toxin-producing E. coli (STEC) can give rise to a range of clinical outcomes from diarrhea to the life-threatening systemic condition, hemolytic uremic syndrome (HUS). A major outbreak of HUS occurred in 2011, and was caused by a rare serotype, STEC O104:H4. Prior to 2011 and since the outbreak, STEC O104:H4 were rarely associated with human infections. Method(s): From 2012 to 2020 intensified STEC surveillance was performed in Germany where subtyping of ~8,000 clinical isolates by molecular methods including whole genome sequencing was carried out. Virulence traits and phylogenetic context were investigated for a subset of strains. Result(s): A rare STEC serotype O181:H4 associated with HUS was identified, belonging to sequence type (ST) 678, like the STEC O104:H4 outbreak strain. Virulence and genomic comparisons revealed that the two strains are phylogenetically related and differ principally in the gene cluster encoding their respective lipopolysaccharide O-antigens. In addition, five other serotypes belonging to ST678 from human clinical infection were identified from diverse locations worldwide. Conclusion(s): Our data suggest the high virulence ensemble of STEC O104:H4 remains a global threat, but that horizontal exchange of O-antigen gene clusters has cloaked the pathogen with new O-antigens, confounding interpretation of their potential risk.

Reported Cases of Multisystem Inflammatory Syndrome in Children (MIS-C) Aged 12-20 Years in the United States Who Received COVID-19 Vaccine, December 2020 through August 2021 (preprint)
Yousaf AR , Cortese MM , Taylor AW , Broder KR , Oster ME , Wong JM , Guh AY , McCormick DW , Kamidani S , Schlaudecker EP , Edwards K , Creech CB , Staat MA , Belay ED , Marquez P , Su JR , Salzman MB , Thompson D , Campbell AP , Museru O , Howard LM , Parise M , Finn LE , Kim M , Raman KV , Komatsu KK , Spiker BL , Burkholder CP , Lang SM , Soslow JH . medRxiv 2022 05 Background: Multisystem inflammatory syndrome in children (MIS-C) is a hyperinflammatory condition associated with antecedent SARS-CoV-2 infection. In the United States, reporting of MIS-C after vaccination is required under COVID-19 vaccine emergency use authorizations. This case series describes persons aged 12-20 years with MIS-C following COVID-19 vaccination reported to passive surveillance systems or through clinician outreach to CDC. Method(s): We investigated potential cases of MIS-C after COVID-19 vaccination reported to CDC's health department-based national MIS-C surveillance, the Vaccine Adverse Event Reporting System (VAERS, co-administered by CDC and the U.S. FDA), and CDC's Clinical Immunization Safety Assessment Project (CISA) from December 14, 2020, to August 31, 2021. We describe cases meeting the CDC MIS-C case definition. Any positive SARS-CoV-2 serology test satisfied the case criteria although anti-nucleocapsid antibody indicates SARS-CoV-2 infection, while anti-spike protein antibody indicates either infection or COVID-19 vaccination. Finding(s): We identified 21 persons with MIS-C after COVID-19 vaccination. Of these 21 persons, median age was 16 years (range, 12-20 years); 13 (62%) were male. All were hospitalized; 12 (57%) had intensive care unit admission, and all were discharged home. Fifteen (71%) of the 21 had laboratory evidence of past or recent SARS-CoV-2 infection, and six (29%) did not. Through August 2021, 21,335,331 persons aged 12-20 years had received >=1 dose of COVID-19 vaccine, making the overall reporting rate for MIS-C following vaccination 1.0 case per million persons receiving >=1 vaccine dose in this age group. The reporting rate for those without evidence of SARS-CoV-2 infection was 0.3 cases per million vaccinated persons. Interpretation(s): In our case series, we describe a small number of persons with MIS-C who had received >=1 COVID-19 vaccine dose before illness onset. Continued reporting of potential cases and surveillance for MIS-C illnesses after COVID-19 vaccination is warranted.

O-antigen diversification masks identification of highly pathogenic shiga toxin-producing Escherichia coli O104:H4-like strains
Lang C , Fruth A , Campbell IW , Jenkins C , Smith P , Strockbine N , Weill FX , Nübel U , Grad YH , Waldor MK , Flieger A . Microbiol Spectr 2023 11 (3) e0098723 Shiga toxin-producing Escherichia coli (STEC) can give rise to a range of clinical outcomes from diarrhea to the life-threatening systemic condition hemolytic-uremic syndrome (HUS). Although STEC O157:H7 is the serotype most frequently associated with HUS, a major outbreak of HUS occurred in 2011 in Germany and was caused by a rare serotype, STEC O104:H4. Prior to 2011 and since the outbreak, STEC O104:H4 strains have only rarely been associated with human infections. From 2012 to 2020, intensified STEC surveillance was performed in Germany where the subtyping of ~8,000 clinical isolates by molecular methods, including whole-genome sequencing, was carried out. A rare STEC serotype, O181:H4, associated with HUS was identified, and like the STEC O104:H4 outbreak strain, this strain belongs to sequence type 678 (ST678). Genomic and virulence comparisons revealed that the two strains are phylogenetically related and differ principally in the gene cluster encoding their respective lipopolysaccharide O-antigens but exhibit similar virulence phenotypes. In addition, five other serotypes belonging to ST678 from human clinical infection, such as OX13:H4, O127:H4, OgN-RKI9:H4, O131:H4, and O69:H4, were identified from diverse locations worldwide. IMPORTANCE Our data suggest that the high-virulence ensemble of the STEC O104:H4 outbreak strain remains a global threat because genomically similar strains cause disease worldwide but that the horizontal acquisition of O-antigen gene clusters has diversified the O-antigens of strains belonging to ST678. Thus, the identification of these highly pathogenic strains is masked by diverse and rare O-antigens, thereby confounding the interpretation of their potential risk. |
Profiles of children with cortical visual impairment who use augmentative and alternative communication: A retrospective examination
Blackstone S , Luo F , Barker RM , Sevcik RA , Romski M , Casella V , Roman-Lantzy C . Am J Speech Lang Pathol 2022 31 (6) 2707-2721 PURPOSE: Cortical visual impairment (CVI) is the most common cause of visual impairment in children today and can impact the outcomes of children who rely on augmentative and alternative communication (AAC). This study provides baseline data of 13 children with CVI who used AAC during their first year of participation in an integrated CVI program. One purpose was to describe similarities and differences in the student's demographic, functional vision, communication, and educational profiles. A second purpose was to examine differences in students described with different communicator profiles. METHOD: Archived student records were de-identified and reviewed using a systematic coding scheme. Two researchers independently reviewed and coded all student records. Reliability was established. Measures included CVI Range scores; supports for positioning, mobility, vision, and writing; AAC systems, including modes, access methods, and language representation; communicative competence; self-determination; literacy; and mathematics. RESULTS: The study yielded a rich description of similarities and differences among students at baseline and led to careful consideration of differences among the participants with emergent communicator and context-dependent communicator profiles. CONCLUSIONS: Currently, limited evidence exists that informs practice regarding AAC assessment and intervention for children with CVI. This article describes a small sample of children with CVI who use AAC. Results underscore the need for educators and practitioners to ensure that vision functioning in students with CVI is evaluated carefully and regularly when conducting AAC assessment and intervention and formulating communication or education goals.

MMWR Morb Mortal Wkly Rep 2022 71 (44) 1418-1424 In July 2022, a case of paralytic poliomyelitis resulting from infection with vaccine-derived poliovirus (VDPV) type 2 (VDPV2)(§) was confirmed in an unvaccinated adult resident of Rockland County, New York (1). As of August 10, 2022, poliovirus type 2 (PV2)(¶) genetically linked to this VDPV2 had been detected in wastewater** in Rockland County and neighboring Orange County (1). This report describes the results of additional poliovirus testing of wastewater samples collected during March 9-October 11, 2022, and tested as of October 20, 2022, from 48 sewersheds (the community area served by a wastewater collection system) serving parts of Rockland County and 12 surrounding counties. Among 1,076 wastewater samples collected, 89 (8.3%) from 10 sewersheds tested positive for PV2. As part of a broad epidemiologic investigation, wastewater testing can provide information about where poliovirus might be circulating in a community in which a paralytic case has been identified; however, the most important public health actions for preventing paralytic poliomyelitis in the United States remain ongoing case detection through national acute flaccid myelitis (AFM) surveillance(††) and improving vaccination coverage in undervaccinated communities. Although most persons in the United States are sufficiently immunized, unvaccinated or undervaccinated persons living or working in Kings, Orange, Queens, Rockland, or Sullivan counties, New York should complete the polio vaccination series as soon as possible. |
Toward ending the HIV epidemic: Temporal trends and disparities in early art initiation and early viral suppression among people newly entering HIV care in the United States, 2012-2018

Open Forum Infect Dis 2022 9 (8) ofac336 BACKGROUND: In 2012, the US Department of Health and Human Services updated their HIV treatment guidelines to recommend antiretroviral therapy (ART) for all people with HIV (PWH) regardless of CD4 count. We investigated recent trends and disparities in early receipt of ART prescription and subsequent viral suppression (VS). METHODS: We examined data from ART-naïve PWH newly presenting to HIV care at 13 North American AIDS Cohort Collaboration on Research and Design clinical cohorts in the United States during 2012-2018. We calculated the cumulative incidence of early ART (within 30 days of entry into care) and early VS (within 6 months of ART initiation) using the Kaplan-Meier survival function. Discrete time-to-event models were fit to estimate unadjusted and adjusted associations of early ART and VS with sociodemographic and clinical factors. RESULTS: Among 11 853 eligible ART-naïve PWH, the cumulative incidence of early ART increased from 42% in 2012 to 82% in 2018. The cumulative incidence of early VS among the 8613 PWH who initiated ART increased from 83% in 2012 to 93% in 2018. In multivariable models, factors independently associated with delayed ART and VS included non-Hispanic/Latino Black race, residence in the South census region, being a male with injection drug use acquisition risk, and history of substance use disorder (SUD; all P ≤ .05). CONCLUSIONS: Early ART initiation and VS have substantially improved in the United States since the release of universal treatment guidelines. Disparities by factors related to social determinants of health and SUD demand focused attention on and services for some subpopulations. |
The CDC Worksite Health ScoreCard: A tool to advance workplace health promotion programs and practices
Roemer EC , Kent KB , Goetzel RZ , Krill J , Williams FS , Lang JE . Prev Chronic Dis 2022 19 E32 INTRODUCTION: The CDC Worksite Health ScoreCard (ScoreCard) is a free, publicly available survey tool designed to help employers assess the extent to which they have implemented evidence-based interventions or strategies at their worksites to improve the health and well-being of employees. We examined how, how broadly, and to what effect the ScoreCard has been applied. METHODS: We analyzed peer-reviewed and grey literature along with the ScoreCard database of online submissions from January 2012 through January 2021. Our inclusion criteria were workplace settings, adult working populations, and explicit use of the ScoreCard. RESULTS: We found that the ScoreCard had been used in 1) surveillance efforts by states, 2) health promotion training and technical assistance, 3) research on workplace health promotion program effectiveness, and 4) employer efforts to improve program design, implementation, and evaluation. CONCLUSION: The ScoreCard has been used as intended to support the development, planning, monitoring, and continuous improvement of workplace health promotion programs. Our review revealed gaps in the tool and opportunities to improve it by 1) enhancing surveillance efforts, 2) engaging employers in low-wage industries, 3) adding new questions or topic areas, and 4) conducting quantitative studies on the relationship between improvements in the ScoreCard and employee health and well-being outcomes. |

Lancet Child Adolesc Health 2022 6 (5) 303-312 BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a hyperinflammatory condition associated with antecedent SARS-CoV-2 infection. In the USA, reporting of MIS-C after vaccination is required under COVID-19 vaccine emergency use authorisations. We aimed to investigate reports of individuals aged 12-20 years with MIS-C after COVID-19 vaccination reported to passive surveillance systems or through clinician outreach to the US Centers for Disease Control and Prevention (CDC). METHODS: In this surveillance activity, we investigated potential cases of MIS-C after COVID-19 vaccination reported to CDC's MIS-C national surveillance system, the Vaccine Adverse Event Reporting System (co-administered by CDC and the US Food and Drug Administration), and CDC's Clinical Immunization Safety Assessment Project. A multidisciplinary team adjudicated cases by use of the CDC MIS-C definition. Any positive SARS-CoV-2 serology test satisfied case criteria; although anti-nucleocapsid antibodies indicate previous SARS-CoV-2 infection, anti-spike protein antibodies indicate either past or recent infection or COVID-19 vaccination. We describe the demographic and clinical features of cases, stratified by laboratory evidence of SARS-CoV-2 infection. To calculate the reporting rate of MIS-C, we divided the count of all individuals meeting the MIS-C case definition, and of those without evidence of SARS-CoV-2 infection, by the number of individuals aged 12-20 years in the USA who received one or more COVID-19 vaccine doses up to Aug 31, 2021, obtained from CDC national vaccine surveillance data. FINDINGS: Using surveillance results from Dec 14, 2020, to Aug 31, 2021, we identified 21 individuals with MIS-C after COVID-19 vaccination. Of these 21 individuals, median age was 16 years (range 12-20); 13 (62%) were male and eight (38%) were female. All 21 were hospitalised: 12 (57%) were admitted to an intensive care unit and all were discharged home. 15 (71%) of 21 individuals had laboratory evidence of past or recent SARS-CoV-2 infection, and six (29%) did not. As of Aug 31, 2021, 21 335 331 individuals aged 12-20 years had received one or more doses of a COVID-19 vaccine, making the overall reporting rate for MIS-C after vaccination 1·0 case per million individuals receiving one or more doses in this age group. The reporting rate in only those without evidence of SARS-CoV-2 infection was 0·3 cases per million vaccinated individuals. INTERPRETATION: Here, we describe a small number of individuals with MIS-C who had received one or more doses of a COVID-19 vaccine before illness onset; the contribution of vaccination to these illnesses is unknown. Our findings suggest that MIS-C after COVID-19 vaccination is rare. Continued reporting of potential cases and surveillance for MIS-C illnesses after COVID-19 vaccination is warranted.

Myocarditis Cases Reported After mRNA-Based COVID-19 Vaccination in the US From December 2020 to August 2021.
Oster ME , Shay DK , Su JR , Gee J , Creech CB , Broder KR , Edwards K , Soslow JH , Dendy JM , Schlaudecker E , Lang SM , Barnett ED , Ruberg FL , Smith MJ , Campbell MJ , Lopes RD , Sperling LS , Baumblatt JA , Thompson DL , Marquez PL , Strid P , Woo J , Pugsley R , Reagan-Steiner S , DeStefano F , Shimabukuro TT . JAMA 2022 327 (4) 331-340 IMPORTANCE: Vaccination against COVID-19 provides clear public health benefits, but vaccination also carries potential risks. The risks and outcomes of myocarditis after COVID-19 vaccination are unclear. OBJECTIVE: To describe reports of myocarditis and the reporting rates after mRNA-based COVID-19 vaccination in the US. DESIGN, SETTING, AND PARTICIPANTS: Descriptive study of reports of myocarditis to the Vaccine Adverse Event Reporting System (VAERS) that occurred after mRNA-based COVID-19 vaccine administration between December 2020 and August 2021 in 192 405 448 individuals older than 12 years of age in the US; data were processed by VAERS as of September 30, 2021. EXPOSURES: Vaccination with BNT162b2 (Pfizer-BioNTech) or mRNA-1273 (Moderna). MAIN OUTCOMES AND MEASURES: Reports of myocarditis to VAERS were adjudicated and summarized for all age groups. Crude reporting rates were calculated across age and sex strata. Expected rates of myocarditis by age and sex were calculated using 2017-2019 claims data. For persons younger than 30 years of age, medical record reviews and clinician interviews were conducted to describe clinical presentation, diagnostic test results, treatment, and early outcomes. RESULTS: Among 192 405 448 persons receiving a total of 354 100 845 mRNA-based COVID-19 vaccines during the study period, there were 1991 reports of myocarditis to VAERS and 1626 of these reports met the case definition of myocarditis. Of those with myocarditis, the median age was 21 years (IQR, 16-31 years) and the median time to symptom onset was 2 days (IQR, 1-3 days). Males comprised 82% of the myocarditis cases for whom sex was reported. The crude reporting rates for cases of myocarditis within 7 days after COVID-19 vaccination exceeded the expected rates of myocarditis across multiple age and sex strata. The rates of myocarditis were highest after the second vaccination dose in adolescent males aged 12 to 15 years (70.7 per million doses of the BNT162b2 vaccine), in adolescent males aged 16 to 17 years (105.9 per million doses of the BNT162b2 vaccine), and in young men aged 18 to 24 years (52.4 and 56.3 per million doses of the BNT162b2 vaccine and the mRNA-1273 vaccine, respectively). There were 826 cases of myocarditis among those younger than 30 years of age who had detailed clinical information available; of these cases, 792 of 809 (98%) had elevated troponin levels, 569 of 794 (72%) had abnormal electrocardiogram results, and 223 of 312 (72%) had abnormal cardiac magnetic resonance imaging results. Approximately 96% of persons (784/813) were hospitalized and 87% (577/661) of these had resolution of presenting symptoms by hospital discharge. The most common treatment was nonsteroidal anti-inflammatory drugs (589/676; 87%). CONCLUSIONS AND RELEVANCE: Based on passive surveillance reporting in the US, the risk of myocarditis after receiving mRNA-based COVID-19 vaccines was increased across multiple age and sex strata and was highest after the second vaccination dose in adolescent males and young men. This risk should be considered in the context of the benefits of COVID-19 vaccination. |
Behavioral and Socioemotional Outcomes of the Legacy for Children Randomized Control Trial to Promote Healthy Development of Children Living in Poverty, 2 to 6 Years Postintervention
Barry CM , Robinson LR , Kaminski JW , Danielson ML , Jones CL , Lang DL . J Dev Behav Pediatr 2021 43 (1) e39-e47 OBJECTIVE: The objective of this article was to assess the impact on behavioral and socioemotional development, 2 to 6 years postintervention (depending on the curriculum), of Legacy for Children, a public health approach to improve child developmental outcomes among families living in poverty. METHODS: Mothers who were recruited prenatally or at the time of childbirth participated in a set of Legacy parallel design randomized control trials between 2001 and 2009 in Miami, Florida, or Los Angeles, California. Of the initial 574 mother-child dyads, 364 completed at least 1 behavioral or socioemotional outcome measure at the third-grade follow-up. Intention-to-treat analyses compared Legacy and comparison groups on behavioral and socioemotional outcomes. RESULTS: Children of Legacy mothers in Los Angeles were at lower risk for externalizing behaviors and poor adaptive skills than children whose mothers did not participate in the intervention. No significant outcome differences by group assignment were found in Miami. CONCLUSION: Group-based positive parenting interventions such as Legacy may have a sustained impact on children's behavioral and socioemotional development several years after intervention completion. |
Effects of Dating Matters on sexual violence and sexual harassment outcomes among middle school youth: A cluster-randomized controlled trial
DeGue S , Niolon PH , Estefan LF , Tracy AJ , Le VD , Vivolo-Kantor AM , Little TD , Latzman NE , Tharp A , Lang KM , Taylor B . Prev Sci 2020 22 (2) 175-185 Sexual violence (SV), including sexual harassment (SH), is a significant public health problem affecting adolescent health and well-being. This study extends prior research by evaluating the effectiveness of a comprehensive teen dating violence prevention model, Dating Matters, on SV and SH perpetration and victimization, inclusive of any victim-perpetrator relationship, among middle school students. Dating Matters includes classroom-delivered programs for youth in 6th, 7th, and 8th grades; community-based programs for parents; a youth communications program; training for educators; and community-level activities. Middle schools in four urban areas in the USA were randomly assigned to receive Dating Matters (DM, N = 22) or a standard-of-care intervention (SC, N = 24) over four consecutive school years (2012-2016). The analytic sample included two cohorts who entered the study in 6th grade and completed 8th grade by the end of the study allowing for full exposure to Dating Matters (DM: N = 1662; SC: N = 1639; 53% female; 50% black, non-Hispanic; 6 waves of data collection for each cohort). Structural equation modeling was employed with multiple imputation to account for missing data. Dating Matters was associated with significant reductions in SV and SH perpetration and victimization scores in most-but not all-sex/cohort groups by the end of 8th grade relative to an evidence-based TDV prevention program. On average, students receiving Dating Matters scored 6% lower on SV perpetration, 3% lower on SV victimization, 4% lower on SH perpetration, and 8% lower on SH victimization by the end of middle school than students receiving an evidence-based violence prevention program. Overall, Dating Matters shows promise for reducing SV and SH, occurring both within and outside dating relationships, through middle school. Clinicaltrials.gov Identifier: NCT01672541. |

PLoS One 2020 15 (9) e0238342 Coronavirus disease 2019 (COVID-19), the respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China and has since become pandemic. In response to the first cases identified in the United States, close contacts of confirmed COVID-19 cases were investigated to enable early identification and isolation of additional cases and to learn more about risk factors for transmission. Close contacts of nine early travel-related cases in the United States were identified and monitored daily for development of symptoms (active monitoring). Selected close contacts (including those with exposures categorized as higher risk) were targeted for collection of additional exposure information and respiratory samples. Respiratory samples were tested for SARS-CoV-2 by real-time reverse transcription polymerase chain reaction at the Centers for Disease Control and Prevention. Four hundred four close contacts were actively monitored in the jurisdictions that managed the travel-related cases. Three hundred thirty-eight of the 404 close contacts provided at least basic exposure information, of whom 159 close contacts had ≥1 set of respiratory samples collected and tested. Across all actively monitored close contacts, two additional symptomatic COVID-19 cases (i.e., secondary cases) were identified; both secondary cases were in spouses of travel-associated case patients. When considering only household members, all of whom had ≥1 respiratory sample tested for SARS-CoV-2, the secondary attack rate (i.e., the number of secondary cases as a proportion of total close contacts) was 13% (95% CI: 4-38%). The results from these contact tracing investigations suggest that household members, especially significant others, of COVID-19 cases are at highest risk of becoming infected. The importance of personal protective equipment for healthcare workers is also underlined. Isolation of persons with COVID-19, in combination with quarantine of exposed close contacts and practice of everyday preventive behaviors, is important to mitigate spread of COVID-19. |

Emerg Infect Dis 2020 26 (8) 1671-1678 We describe the contact investigation for an early confirmed case of coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in the United States. Contacts of the case-patient were identified, actively monitored for symptoms, interviewed for a detailed exposure history, and tested for SARS-CoV-2 infection by real-time reverse transcription PCR (rRT-PCR) and ELISA. Fifty contacts were identified and 38 (76%) were interviewed, of whom 11 (29%) reported unprotected face-to-face interaction with the case-patient. Thirty-seven (74%) had respiratory specimens tested by rRT-PCR, and all tested negative. Twenty-three (46%) had ELISA performed on serum samples collected approximately 6 weeks after exposure, and none had detectable antibodies to SARS-CoV-2. Among contacts who were tested, no secondary transmission was identified in this investigation, despite unprotected close interactions with the infectious case-patient. |
Effects of the Dating Matters(R) comprehensive prevention model on health- and delinquency-related risk behaviors in middle school youth: A cluster-randomized controlled trial
Estefan LF , Vivolo-Kantor AM , Niolon PH , Le VD , Tracy AJ , Little TD , DeGue S , Latzman NE , Tharp A , Lang KM , McIntosh WL . Prev Sci 2020 22 (2) 163-174 Teen dating violence (TDV) is associated with a variety of delinquent behaviors, such as theft, and health- and delinquency-related risk behaviors, including alcohol use, substance abuse, and weapon carrying. These behaviors may co-occur due to shared risk factors. Thus, comprehensive TDV-focused prevention programs may also impact these other risk behaviors. This study examined the effectiveness of CDC's Dating Matters(R): Strategies to Promote Healthy Teen Relationships (Dating Matters) comprehensive TDV prevention model compared to a standard-of-care condition on health- and delinquency-related risk behaviors among middle school students. Students (N = 3301; 53% female; 50% black, non-Hispanic; and 31% Hispanic) in 46 middle schools in four sites across the USA were surveyed twice yearly in 6th, 7th, and 8th grades. A structural equation modeling framework with multiple imputation to account for missing data was utilized. On average over time, students receiving Dating Matters scored 9% lower on a measure of weapon carrying, 9% lower on a measure of alcohol and substance abuse, and 8% lower on a measure of delinquency by the end of middle school than students receiving an evidence-based standard-of-care TDV prevention program. Dating Matters demonstrated protective effects for most groups of students through the end of middle school. These results suggest that this comprehensive model is successful at preventing risk behaviors associated with TDV. clinicaltrials.gov Identifier: NCT01672541. |
Emergency preparedness training for hospital nursing staff, New York City, 2012-2016
Jacobs-Wingo JL , Schlegelmilch J , Berliner M , Airall-Simon G , Lang W . J Nurs Scholarsh 2019 51 (1) 81-87 PURPOSE: Many nurses are trained inadequately in emergency preparedness (EP), preventing them from effectively executing response roles during disasters, such as chemical, biological, radiological, nuclear, and explosive (CBRNE) events. Nurses also indicate lacking confidence in their abilities to perform EP activities. The purpose of this article is to describe the phased development of, and delivery strategies for, a CBRNE curriculum to enhance EP among nursing professionals. The New York City (NYC) Department of Health and Mental Hygiene (DOHMH) and the National Center for Disaster Preparedness at Columbia University's Earth Institute led the initiative. METHODS: Curriculum development included four phases. In Phases I and II, nursing staff at 20 participating NYC hospitals conducted 7,177 surveys and participated in 20 focus groups to identify training gaps in EP. In Phase III, investigators developed and later refined the CBRNE curriculum based on gaps identified. In Phase IV, 22 nurse educators (representing 7 of the original 20 participating hospitals) completed train-the-trainer sessions. Of these nurse educators, three were evaluated on their ability to train other nurses using the curriculum, which investigators finalized. FINDINGS: The CBRNE curriculum included six modules, a just-in-time training, and an online annual refresher course that addressed EP gaps identified in surveys and focus groups. Among the 11 nurses who were trained by three nurse educators during a pilot training, participant knowledge of CBRNE events and response roles increased from an average of 54% (range 45%-75%) on the pre-test to 89% (range 80%-90%) on the posttest. CONCLUSIONS: By participating in nursing CBRNE training, nurses increased their knowledge of and preparedness to respond to disasters. The train-the-trainer curriculum is easily adaptable to meet the needs of other healthcare settings. CLINICAL RELEVANCE: The CBRNE curriculum can be used to train nurses to better prepare for and more effectively respond to disasters. |
The CDC Worksite Health ScoreCard: An assessment tool to promote employee health and well-being
Lang JE , Mummert A , Roemer EC , Kent KB , Koffman DM , Goetzel RZ . Am J Health Promot 2020 34 (3) 319-321 The Centers for Disease Control and Prevention (CDC) Worksite Health ScoreCard (CDC ScoreCard) is a free and publicly available tool designed and validated to help employers assess the extent to which they have implemented evidence-based health promotion interventions or strategies at their worksites to improve the health and well-being of their employees.1 The current version of the CDC ScoreCard has 154 yes/no questions that address a range of health promotion and disease prevention strategies, including lifestyle counseling services, physical/social environmental supports, workplace policies, and health plan benefits across 18 core topic areas (see Table 1). Each question represents an individual intervention, strategy, or action an employer can put into practice at the worksite. |
Prevalence of workplace health practices and policies in hospitals: Results from the Workplace Health in America Study
Mulder L , Belay B , Mukhtar Q , Lang JE , Harris D , Onufrak S . Am J Health Promot 2020 34 (8) 890117120905232 PURPOSE: To provide a nationally representative description on the prevalences of policies, practices, programs, and supports relating to worksite wellness in US hospitals. DESIGN: Cross-sectional, self-report of hospitals participating in Workplace Health in America (WHA) survey from November 2016 through September 2017. SETTING: Hospitals across the United States. PARTICIPANTS: Random sample of 338 eligible hospitals participating in the WHA survey. MEASURES: We used previous items from the 2004 National Worksite Health Promotion survey. Key measures included presence of Worksite Health Promotion programs, evidence-based strategies, health screenings, disease management programs, incentives, work-life policies, barriers to health promotion program implementation, and occupational safety and health. ANALYSIS: Independent variables included hospital characteristics (eg, size). Dependent characteristics included worksite health promotion components. Descriptive statistics and chi(2) analyses were used. RESULTS: Eighty-two percent of hospitals offered a wellness programs during the previous year with larger hospitals more likely than smaller hospitals to offer programs (P < .01). Among hospitals with wellness programs, 69% offered nutrition programs, 74% offered physical activity (PA) programs, and 84% had a policy to restrict all tobacco use. Among those with cafeterias or vending machines, 40% had a policy for healthier foods. Only 47% and 25% of hospitals offered lactation support or healthy sleep programs, respectively. CONCLUSION: Most hospitals offer wellness programs. However, there remain hospitals that do not offer wellness programs. Among those that have wellness programs, most offer supports for nutrition, PA, and tobacco control. Few hospitals offered programs on healthy sleep or lactation support. |
Middle school effects of the Dating Matters(R) Comprehensive Teen Dating Violence Prevention Model on physical violence, bullying, and cyberbullying: A cluster-randomized controlled trial
Vivolo-Kantor AM , Niolon PH , Estefan LF , Le VD , Tracy AJ , Latzman NE , Little TD , Lang KM , DeGue S , Tharp AT . Prev Sci 2019 22 (2) 151-161 Few comprehensive primary prevention approaches for youth have been evaluated for effects on multiple types of violence. Dating Matters(R): Strategies to Promote Healthy Teen Relationships (Dating Matters) is a comprehensive teen dating violence (TDV) prevention model designed by the Centers for Disease Control and Prevention and evaluated using a longitudinal stratified cluster-randomized controlled trial to determine effectiveness for preventing TDV and promoting healthy relationship behaviors among middle school students. In this study, we examine the prevention effects on secondary outcomes, including victimization and perpetration of physical violence, bullying, and cyberbullying. This study examined the effectiveness of Dating Matters compared to a standard-of-care TDV prevention program in 46 middle schools in four high-risk urban communities across the USA. The analytic sample (N = 3301; 53% female; 50% Black, non-Hispanic; and 31% Hispanic) consisted of 6th-8th grade students who had an opportunity for exposure to Dating Matters in all three grades or the standard-of-care in 8th grade only. Results demonstrated that both male and female students attending schools implementing Dating Matters reported 11% less bullying perpetration and 11% less physical violence perpetration than students in comparison schools. Female Dating Matters students reported 9% less cyberbullying victimization and 10% less cyberbullying perpetration relative to the standard-of-care. When compared to an existing evidence-based intervention for TDV, Dating Matters demonstrated protective effects on physical violence, bullying, and cyberbullying for most groups of students. The Dating Matters comprehensive prevention model holds promise for reducing multiple forms of violence among middle school-aged youth. ClinicalTrials.gov Identifier: NCT01672541. |

Roemer EC , Kent KB , Mummert A , McCleary K , Palmer JB , Lang JE , Matson-Koffman D , Goetzel RZ . J Occup Environ Med 2019 61 (9) 767-777 OBJECTIVE: To evaluate the reliability and validity of the updated 2019 CDC Worksite Health ScoreCard (CDC ScoreCard), which includes four new modules. METHODS: We pilot tested the updated instrument at 93 worksites, examining question response concurrence between two representatives from each worksite. We conducted cognitive interviews and site visits to evaluate face validity, and refined the instrument for public distribution. RESULTS: The mean question concurrence rate was 73.4%. Respondents reported the tool to be useful for assessing current workplace programs and planning future initiatives. On average, 43% of possible interventions included in the CDC ScoreCard were in place at the pilot sites. CONCLUSIONS: The updated CDC ScoreCard is a valid and reliable tool for assessing worksite health promotion policies, educational and lifestyle counseling programs, environmental supports, and health benefits. |
An RCT of Dating Matters: Effects on Teen Dating Violence and Relationship Behaviors
Niolon PH , Vivolo-Kantor AM , Tracy AJ , Latzman NE , Little TD , DeGue S , Lang KM , Estefan LF , Ghazarian SR , McIntosh WLK , Taylor B , Johnson LL , Kuoh H , Burton T , Fortson B , Mumford EA , Nelson SC , Joseph H , Valle LA , Tharp AT . Am J Prev Med 2019 57 (1) 13-23 INTRODUCTION: Teen dating violence is a serious public health problem with few effective prevention strategies. This study examines whether the Dating Matters comprehensive prevention model, compared with a standard of care intervention, prevented negative relationship behaviors and promoted positive relationship behaviors. STUDY DESIGN: This longitudinal, cluster-RCT compared the effectiveness of Dating Matters with standard of care across middle school. Standard of care was an evidence-based teen dating violence prevention curriculum (Safe Dates) implemented in eighth grade. SETTING/PARTICIPANTS: Forty-six middle schools in high-risk urban neighborhoods in four U.S. cities were randomized. Schools lost to follow-up were replaced with new schools, which were independently randomized (71% school retention). Students were surveyed in fall and spring of sixth, seventh, and eighth grades (2012-2016). The analysis sample includes students from schools implementing Dating Matters or standard of care for >2 years who started sixth grade in the fall of 2012 or 2013 and had dated (N=2,349 students, mean age 12 years, 49% female, and 55% black, non-Hispanic, 28% Hispanic, 17% other). INTERVENTION: Dating Matters is a comprehensive, multicomponent prevention model including classroom-delivered programs for sixth to eighth graders, training for parents of sixth to eighth graders, educator training, a youth communications program, and local health department activities to assess capacity and track teen dating violence-related policy and data. MAIN OUTCOME MEASURES: Self-reported teen dating violence perpetration and victimization, use of negative conflict resolution strategies, and positive relationship skills were examined as outcomes. Imputation and analyses were conducted in 2017. RESULTS: Latent panel models demonstrated significant program effects for three of four outcomes; Dating Matters students reported 8.43% lower teen dating violence perpetration, 9.78% lower teen dating violence victimization, and 5.52% lower use of negative conflict resolution strategies, on average across time points and cohorts, than standard of care students. There were no significant effects on positive relationship behaviors. CONCLUSIONS: Dating Matters demonstrates comparative effectiveness, through middle school, for reducing unhealthy relationship behaviors, such as teen dating violence and use of negative conflict resolution strategies, relative to the standard of care intervention. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.gov NCT01672541. |
Results of the Workplace Health in America Survey
Linnan LA , Cluff L , Lang JE , Penne M , Leff MS . Am J Health Promot 2019 33 (5) 890117119842047 PURPOSE: To provide a nationally representative snapshot of workplace health promotion (WHP) and protection practices among United States worksites. DESIGN: Cross-sectional, self-report Workplace Health in America (WHA) Survey between November 2016 and September 2017. SETTING: National. PARTICIPANTS: Random sample of US worksites with >/=10 employees, stratified by region, size, and North American Industrial Classification System sector. MEASURES: Workplace health promotion programs, program administration, evidence-based strategies, health screenings, disease management, incentives, work-life policies, implementation barriers, and occupational safety and health (OSH). ANALYSIS: Descriptive statistics, t tests, and logistic regression. RESULTS: Among eligible worksites, 10.1% (n = 3109) responded, 2843 retained in final sample, and 46.1% offered some type of WHP program. The proportion of comparable worksites with comprehensive programs (as defined in Healthy People 2010) rose from 6.9% in 2004 to 17.1% in 2017 ( P < .001). Occupational safety and health programs were more prevalent than WHP programs, and 83.5% of all worksites had an individual responsible for employee safety, while only 72.2% of those with a WHP program had an individual responsible for it. Smaller worksites were less likely than larger to offer most programs. CONCLUSION: The prevalence of WHP programs has increased but remains low across most health programs; few worksites have comprehensive programs. Smaller worksites have persistent deficits and require targeted approaches; integrated OSH and WHP efforts may help. Ongoing monitoring using the WHA Survey benchmarks OSH and WHP in US worksites, updates estimates from previous surveys, and identifies gaps in research and practice. |
CDC Grand Rounds: New frontiers in workplace health
Fischer LS , Lang JE , Goetzel RZ , Linnan LA , Thorpe PG . MMWR Morb Mortal Wkly Rep 2018 67 (41) 1156-1159 Approximately 150 million Americans go to work each day, and where and how they work are closely linked to health and disease. Thus, workplace health promotion programs provide an opportunity to affect the health of the nation. Workplace health promotion programs traditionally rooted in occupational safety and health focus on preventing injury and illness resulting from the workplace environment. As gains have been made in reducing workplace hazards, and the prevalence of disease has shifted toward chronic diseases, employers have encountered rising health care costs. In the United States, chronic diseases are responsible for approximately seven in 10 deaths and account for 86% of health care costs (1,2). Approximately 20% of employer health care spending is associated with 10 modifiable health risks in the U.S. workforce: depression, high blood glucose, high blood pressure, obesity, tobacco use, physical inactivity, high stress, high cholesterol, poor nutrition and eating habits, and high alcohol consumption (3). Many employers have sought to establish workplace health promotion programs to improve employee health and lower health care costs; results of these efforts have been mixed. For example, some employers, especially smaller firms with limited resources, report barriers to implementing workplace health promotion programs, including lack of knowledge of program design, difficulty identifying credible information, and lack of awareness of program benefits (4,5). Evaluation and research continue to increase knowledge about workplace health promotion program design and identify ways to overcome the challenges of establishing effective programs. State health departments can provide assistance to employers and employees. In 2017, the CDC Workplace Health Resource Center was launched as a source for reliable evidence and best practices to improve worker health and productivity, address research gaps, and potentially reduce health care costs. |
Bat rabies in Washington State: Temporal-spatial trends and risk factors for zoonotic transmission (2000-2017)
Bonwitt J , Oltean H , Lang M , Kelly RM , Goldoft M . PLoS One 2018 13 (10) e0205069 BACKGROUND: Rabies is a zoonotic viral disease that can affect all mammals. In the United States, the majority of human rabies cases are caused by bats, which are the only known reservoirs for rabies virus (RABV) in Washington State. We sought to characterize bat RABV epidemiology in Washington among bats submitted by the public for RABV testing. METHODS: We examined temporal and spatial trends in RABV positivity (% positive) for taxonomically identified bats submitted to diagnostic laboratories during 2006-2017. For a subset of Myotis species, we evaluated sensitivity and predictive value positive (PPV) of morphological identification keys, using mitochondrial markers (cytochrome b) as a reference. For bats tested during 2000-2016, we analyzed RABV positivity by circumstances of encounters with humans, cats, and dogs. RESULTS: During 2006-2017, RABV positivity for all bat species was 6.0% (176/2,928). Among species with >/=100 submissions, RABV positivity was 2.0%-11.7% and highest among big brown bats (Eptesicus fuscus). An increasing trend in annual positivity was significant only for big brown bats (P = 0.02), and was circumstantially linked to a geographic cluster. Sensitivity and PPV of morphological identification keys was high for M. evotis but varied for M. lucifugus, M. californicus, M. yumanensis, and M. septentrionalis. A positive RABV result was significantly associated with nonsynanthropic species, abnormal behavior, abnormal hiding, injury, biting, found in a body of water, found alive, found outdoors, and caught by a dog. CONCLUSION: Monitoring passive RABV surveillance trends enables public health authorities to perform more accurate risk assessments. Differences in temporal and spatial trends in RABV positivity by bat species indicate the importance of collecting taxonomic data, although morphological identification can be unreliable for certain Myotis species. Current public health practices for RABV exposures should be maintained as RABV infection in bats can never be excluded without diagnostic testing. |
Quantification of microcystin-LR in human urine by immunocapture liquid chromatography tandem mass spectrometry
Wharton RE , Ojeda-Torres G , Cunningham B , Feyereisen MC , Hill KL , Abbott NL , Seymour C , Hill D , Lang J , Hamelin EI , Johnson RC . Chem Res Toxicol 2018 31 (9) 898-903 Microcystins are toxins produced by many cyanobacteria species, which are often released into waterways during blue-green algal blooms in freshwater and marine habitats. The consumption of microcystin-contaminated water is a public health concern as these toxins are recognized tumor promoters and are hepatotoxic to humans and animals. A method to confirm human exposures to microcystins is needed; therefore, our laboratory has developed an immunocapture liquid chromatography tandem mass spectrometry (LC-MS/MS) method targeting the conserved adda portion of microcystins for the quantitation of a prevalent and highly toxic congener of microcystin, microcystin-LR (MC-LR). An acute exposure method was initially evaluated for accuracy and precision by analyzing calibrators and quality control (QC) samples ranging from 0.500 to 75.0 ng/mL in urine. All calibrators and QC samples characterized were within 15% of theoretical concentrations. An analysis of acutely exposed mouse urine samples using this method identified MC-LR levels from 10.7 to 33.9 ng/mL. Since human exposures are anticipated to result from low-dose or chronic exposures, a high-sensitivity method was validated with 20 calibration curves and QC samples ranging from 0.0100 to 7.50 ng/mL. Relative standard deviations (RSDs) and inaccuracies of these samples were within 15%, meeting United States Food and Drug Administration (FDA) guidelines for analytical methods, and the limit of detection was 0.00455 ng/mL. In conclusion, we have developed a method which can be used to address public health concerns by precisely and accurately measuring MC-LR in urine samples. |
High completion rate for 12 weekly doses of isoniazid and rifapentine as treatment for latent Mycobacterium tuberculosis infection in the Federal Bureau of Prisons
Schmit KM , Lobato MN , Lang SG , Wheeler S , Kendig NE , Bur S . J Public Health Manag Pract 2018 25 (2) E1-E6 CONTEXT: Correctional facilities provide unique opportunities to diagnose and treat persons with latent tuberculosis infection (LTBI). Studies have shown that 12 weekly doses of isoniazid and rifapentine (INH-RPT) to treat LTBI resulted in high completion rates with good tolerability. OBJECTIVE: To evaluate completion rates and clinical signs or reported symptoms associated with discontinuation of 12 weekly doses of INH-RPT for LTBI treatment. SETTING/PARTICIPANTS: During July 2012 to February 2015, 7 Federal Bureau of Prisons facilities participated in an assessment of 12 weekly doses of INH-RPT for LTBI treatment among 463 inmates. MAIN OUTCOME MEASURES: Fisher exact test was used to assess the associations between patient sociodemographic characteristics and clinical signs or symptoms with discontinuation of treatment. RESULTS: Of 463 inmates treated with INH-RPT, 424 (92%) completed treatment. Reasons for discontinuation of treatment for 39 (8%) inmates included the following: 17 (44%) signs/symptoms, 9 (23%) transfer or release, 8 (21%) treatment refusal, and 5 (13%) provider error. A total of 229 (49.5%) inmates reported experiencing at least 1 sign or symptom during treatment; most frequently reported were fatigue (16%), nausea (13%), and abdominal pain (7%). Among these 229 inmates, signs/symptoms significantly associated with discontinuation of treatment included abdominal pain (P < .001), appetite loss (P = .02), fever/chills (P = .01), nausea (P = .03), sore muscles (P = .002), and elevation of liver transaminases 5x upper limits of normal or greater (P = .03). CONCLUSIONS: The LTBI completion rates were high for the INH-RPT regimen, with few inmates discontinuing because of signs or symptoms related to treatment. This regimen also has practical advantages to aid in treatment completion in the correctional setting and can be considered a viable alternative to standard LTBI regimens. |
Elements of a workplace culture of health, perceived organizational support for health, and lifestyle risk
Payne J , Cluff L , Lang J , Matson-Koffman D , Morgan-Lopez A . Am J Health Promot 2018 32 (7) 890117118758235 PURPOSE: We investigated the impact of elements of a workplace culture of health (COH) on employees' perceptions of employer support for health and lifestyle risk. DESIGN: We used 2013 and 2015 survey data from the National Healthy Worksite Program, a Centers for Disease Control and Prevention (CDC)-led initiative to help workplaces implement health-promoting interventions. SETTING: Forty-one employers completed the CDC Worksite Health Scorecard to document organizational changes. PARTICIPANTS: Eight hundred twenty-five employees provided data to evaluate changes in their health and attitudes. MEASURES: We defined elements of a COH as environmental, policy, and programmatic supports; leadership and coworker support; employee engagement (motivational interventions); and strategic communication. Outcomes included scores of employees' perceptions of employer support for health and lifestyle risk derived from self-reported physical activity, nutrition, and tobacco use. ANALYSIS: We estimated effects using multilevel regression models. RESULTS: At the employee level and across time, regression coefficients show positive associations between leadership support, coworker support, employee engagement, and perceived support for health ( P < .05). Coefficients suggest a marginally significant negative association between lifestyle risk and the presence of environmental and policy supports ( P < .10) and significant associations with leadership support in 2015 only ( P < .05). CONCLUSION: Relational elements of COH (leadership and coworker support) tend to be associated with perceived support for health, while workplace elements (environmental and policy supports) are more associated with lifestyle risk. Employers need to confront relational and workplace elements together to build a COH. |
