Neighborhood greenspace exposure as a protective factor in dementia risk among U.S. adults 75 years or older: a cohort study.

BACKGROUND: Research suggests that greenspace may confer neurocognitive benefits. This study examines whether residential greenspace is associated with risk of dementia among older adults. METHODS: Greenspace exposure was computed for 3047 participants aged 75 years and older enrolled in the Gingko Evaluation of Memory Study (GEMS) across four U.S. sites that prospectively evaluated dementia and its subtypes, Alzheimer's disease (AD), vascular dementia (VaD), and mixed pathologies, using neuropsychiatric evaluations between 2000 and 2008. After geocoding participant residences at baseline, three greenspace metrics-Normalized Difference Vegetative Index, percent park overlap within a 2-km radius, and linear distance to nearest park-were combined to create a composite residential greenspace measure categorized into tertiles. Cox proportional hazards models estimated the associations between baseline greenspace and risk of incident all-cause dementia, AD, and Mixed/VaD. RESULTS: Compared to low residential greenspace, high residential greenspace was associated with a reduced risk of dementia (HR = 0.76 95% CI: 0.59,0.98) in models adjusted for multiple covariates. After additional adjustment for behavioral characteristics, Apolipoprotein E ɛ4 status, and other covariates, the association was slightly attenuated (HR = 0.82; 95% CI:0.63,1.06). Those exposed to medium levels of greenspace also had 28% lower risk (HR = 0.72; CI: 0.55, 0.95) of dementia compared to those with low greenspace in adjusted models. Subtype associations between high residential greenspace and AD were not statistically significant. Greenspace was not found to be significantly associated with mixed/vascular pathologies. CONCLUSIONS: This study showed evidence for an association between residential greenspace and all-cause dementia among older adults. Future research with larger sample size, precise characterization of different dementia subtypes, and assessment of residential greenspace earlier in life may help clarify the role between exposure to greenspace and dementia risk.

Home visitor perspectives on implementing a precision approach to home visiting in communities serving Native American families.

Family Spirit (FS) is a federally endorsed evidence-based home visiting programs serving as a key prevention strategy for expectant families and families with young children. Like other home-visiting programs, it shares client challenges in retention and engagement during implementation. We assessed (1) the feasibility and acceptability of implementing a precision approach to FS; and (2) differences in approaches to FS delivery. Home visitors, serving primarily Native American families, that delivered a standard (N = 6) or a precision approach (N = 6) to FS across four study sites each participated in up to four virtual focus group discussions (FGDs) (N = 16). Facilitators and barriers to implementation were identified across the curriculum approach, relational and contextual levels. Facilitators: Relevant and culturally sensitive lessons, lesson structure, client-home visitor relationship, client buy-in, home visitor autonomy, leadership support, flexible funding, and training. Barriers: Irrelevant lessons, substance use content, missing topics, families experiencing crises, client and home visitor availability, client feedback, nonsupportive leadership, inadequate funding, and organizational policies and practices. The precision approach offers (1) tailoring of lessons that supports relevance of content to clients; and (2) a target timeframe that supports flexibility in lesson delivery. This model structure may improve client participation and retention.

Espíritu de Familia (FS) es un programa de visitas a casa con base en la evidencia y respaldado federalmente, el cual sirve como una estrategia clave de prevención para familias con niños pequeños que esperan otro niño. Tal como otros programas de visitas a casa, éste comparte los retos de los participantes en cuanto a retención y participación activa durante la implementación. Evaluamos 1) la factibilidad y accesibilidad de implementar un acercamiento de precisión a FS; y 2) las diferencias en cuanto al acercamiento del ofrecimiento de FS. Los visitadores a casa, quienes primariamente les sirven a familia nativo-americanas, y que ofrecieron un acercamiento estándar (N = 6) o uno de precisión (N = 6) a FS a través de 4 lugares de estudio, cada uno participó en un máximo de 4 discusiones virtuales de grupos de enfoque (N = 16). Los aspectos que facilitaron y las barreras a la implementación se identificaron a lo largo de los niveles de acercamiento, relacionales y contextuales del currículo. Aspectos que facilitaron: lecciones relevantes y culturalmente sensibles, estructura de lecciones, la relación entre el participante-casa y el visitador, la aceptación por parte del participante, la autonomía del visitador a casa, el apoyo de liderazgo, la flexibilidad de los fondos, así como el entrenamiento. Barreras: lecciones irrelevantes, contenido sobre uso de sustancias, temas que no se incluyeron, las familias que experimentaban una crisis, la disponibilidad del participante y del visitador, información aportada por el participante, falta de apoyo del liderazgo, fondos inadecuados, así como las políticas y prácticas organizacionales. El acercamiento de precisión ofrece 1) moldear las lecciones que apoyan la relevancia del contenido a los participantes; y 2) un definido marco de tiempo que apoya la flexibilidad del ofrecimiento de las lecciones. Esta estructura de modelo pudiera mejorar la participación y retención de participantes.

Le programme Family Spirit (FS, soit Esprit de Famille) est une programme américain, basé sur des données probantes, avalisé par le gouvernement américain, de visite à domicile, servant de stratégie de prévention clé pour les familles attendant un enfant ou les familles avec de jeunes enfants. Comme d'autres programmes de visite à domicile, ce programme partage des difficultés dans la rétention et l'engagement des clients durant la mise en oeuvre. Nous avons évalué 1) la fiabilité et l'acceptabilité de la mise en œuvre d'une approche de précision du FS; et 2) des différences dans les approches de l'application du FS. Les visiteurs à domicile, servant principalement des familles amérindiennes américaines, qui ont présenté une approche standard (N = 6) ou une approche de précision (N = 6) du FS et au travers de 4 sites d'étude chacun ont participé à jusqu'à 4 discussions de groupe d'étude virtuels (n = 16). Les aspects facilitateurs et les barrières à la mise en place ont été identifiés au travers de l'approche du curriculum, des niveaux relationnels et contextuels. Aspects de facilitation: leçons pertinentes et culturellement sensibles, structure de la leçon, relation client-visiteur à domicile, adhésion du client, autonomie du visiteur à domicile, soutient des dirigeants, budget flexible, formation. Barrières: leçons n'étant pas pertinentes, contenu d'usage de substance, sujets qui manquent, familles faisant l'expérience de crises, disponibilité du client et du visiteur à domicile, retour du client, dirigeants qui n'offrent aucun soutien, budget inadéquat, et politiques et pratiques organisationnelles. L'approche de précision offre 1) une adaptation sur mesure des leçons qui soutient la pertinence du contenu pour les clients; et 2) un délai ciblé qui soutient la flexibilité de l'enseignement. Cette structure de modèle peut améliorer la participation et la rétention.

Greenspace exposure and COVID-19 mortality in the United States: January-July 2020.

BACKGROUND: Mortality from the novel coronavirus disease-2019 (COVID-19) continues to rise across the United States. Evidence is emerging that environmental factors may contribute to susceptibility to disease and mortality. Greenspace exposure promotes enhanced immunity and may protect against risk of mortality among those with COVID-19. OBJECTIVES: Our objective was to determine if high county level greenspace exposure is associated with reduced risk of COVID-19 mortality. METHODS: Greenspace exposure was characterized in 3049 counties across the conterminous United States using Leaf Area Index (LAI) deciles that were derived from satellite imagery via Moderate Resolution Imaging Spectroradiometer from 2011 to 2015. COVID-19 mortality data were obtained from the Center for Systems Science and Engineering at Johns Hopkins University. We used a generalized linear mixed model to evaluate the association between county level LAI and COVID-19 mortality rate in analyses adjusted for 2015-2019 county level average total county population, older population, race, overcrowding in home, Medicaid, education, and physical inactivity. RESULTS: A dose-response association was found between greenness and reduced risk of COVID-19 mortality. COVID-19 mortality was negatively associated with LAI deciles 8 [MRR = 0.82 (95% CI: 0.72, 0.93)], 9 [MRR = 0.78 (95% CI: 0.68, 0.89)], and 10 [MRR = 0.59 (95% CI: 0.50, 0.69)]. Aside from LAI decile 5, no associations were found between the remaining LAI deciles and COVID-19 mortality. Increasing prevalence of counties with older age residents, low education attainment, Native Americans, Black Americans, and housing overcrowding were significantly associated with increased risk of COVID-19 mortality, whereas Medicaid prevalence was associated with a reduced risk. DISCUSSION: Counties with a higher amount of greenspace may be at a reduced risk of experiencing mortality due to COVID-19.

Identifying family-child activities among children with prenatal drug exposure in a Tribal Nation: Caregiver perspectives on barriers, facilitators and positive outcomes.

BACKGROUND: Native American newborns experience high rates of prenatal drug exposure leading to devastating outcomes within Indigenous communities. Such children are at heightened risk of maladaptive outcomes if early intervention does not occur. A need exists to identify strategies that promote resilience. OBJECTIVES: Identify barriers and facilitators that families experience in family-child engagement activities across the community, culture, outdoors, and home settings to inform a cultural-sensitive and community-relevant study aimed at quantifying positive family-child engagement activities as a resilience factor in this population. METHODS: Biological parents and caregivers to children, ages 0-3 years old with or without prenatal drug exposure (N = 15) were recruited from the Confederated Salish and Kootenai Tribes to participate in an in-person semi-structured interview. Data analysis consisted of research yarning and directed content analysis to collect unique stories and to identify common activities, barriers, supports and positive outcomes to families, respectively. RESULTS: Attending multiple powwows/celebrations, swimming, and reading were the most mentioned activities. Cost and transportation were common barriers. The most common support mechanism provided was having family or friends present to participate in activities. Cultural knowledge and bonding were common positive outcomes for a child engaging in activities. A collection of stories identified both familial barriers to traditional ways of knowing and participation in community, and community-implemented efforts to bridge that gap among families with a history of drug and alcohol use. CONCLUSIONS: This study identifies potential resilience factors specific to families to children with prenatal drug exposure that reside in Indigenous communities.

Increasing Native Research Leadership Through an Early Career Development Program.

Inequities impact American Indian, Alaska Native, and Native Hawaiian populations across various health conditions; in particular, many Native communities bear a disproportionate burden of substance use disorder. Such inequities persist despite concerted efforts of communities and significant research directed toward prevention and intervention. One factor hampering these efforts is the underrepresentation of researchers who are themselves Native and uniquely equipped to respond to the needs of their communities. This paper describes the innovative Native Children's Research Exchange (NCRE) Scholars program, now entering its ninth year of successful career development support for emerging Native scholars. We summarize the history of NCRE Scholars, outline the mentoring and training approaches taken to meet the unique needs of early-career Native scholars, and present key progress of program alumni. The current cohort of Scholars provide first-person perspectives on how four key program elements have supported their career development to date. NCRE Scholars has been an effective approach for supporting the next generation of Native research leaders and for helping to build an essential mass of Native researchers prepared to respond to Native community health priority needs.

Improving mammography access for women with disabilities: Outcomes of the CDC's right to know campaign.

Women with disabilities share similar risks for breast cancer as other women yet experience a lack of access to cancer screening and are less likely to receive screening mammograms in accordance with recommended guidelines. The present study evaluated mammography centers across the state of Montana in response to the Centers for Disease Control and Prevention's Right to Know campaign, which focused on addressing barriers to breast cancer screening. Mammography centers were originally evaluated in 2009 and were reassessed in 2011 and 2015 after being given action plans to address accessibility barriers. The current study examined changes in accessibility across time in four priority areas: 1) van and standard parking, 2) exterior and interior routes, 3) mammography rooms, and 4) restrooms. Results indicate all mammography centers had a least one mammography machine that lowered for patients in a seated position and that accessibility of the four priority areas improved over time; however, improvements were still needed to encourage health equity for women with disabilities.

Policy compliance of smokers on a tobacco-free university campus.

OBJECTIVES: To explore factors influencing compliance with campus tobacco policies and strategies to increase compliance. PARTICIPANTS: Sixty tobacco smokers (April 2012). METHODS: A 22-item intercept-interview with closed- and open-ended questions was conducted with smokers in adjacent compliant and noncompliant areas at 1 university with a 100% tobacco ban. Data were analyzed using descriptive statistics and content analysis. RESULTS: Most reported that the smoking policy was not enforced. Noncompliant smokers had less knowledge of locations where tobacco use was permitted and were more likely to identify their smoking location as compliant and had knowingly violated the policy. Choice of location to smoke was related to convenience and a desire to follow the policy. Smokers recommended consequences for noncompliance and structures that accommodated smoking to increase adherence to the tobacco ban. CONCLUSIONS: Additional education, environmental, and contingency strategies are needed to increase compliance with the policy banning tobacco use on this campus.
