A Social-Ecological Systems Understanding of Risk & Protective Factors for Loneliness in LGBTQ+ Adults
LGBTQ+ adults are a marginalized population that often experiences high levels of loneliness associated with poor mental and physical health outcomes. However, designing effective interventions can be hindered by the complexity and interdependence of loneliness risk and protective factors. A scoping review was conducted to map the scientific understanding of loneliness risk and protective factors for LGBTQ+ adults to theoretical frameworks that p…
Adult Loneliness Narratives Recount Exposure to Relational Loss, Rejection, Emotional Absence, and Excessive Labor
The U.S. Surgeon General's 2023 advisory on America's loneliness epidemic defines loneliness as a discrepancy in relationship quality linked to higher risk for severe mental illness. It is unclear what is meant by relationship quality and how these qualities would scale large enough to produce a loneliness epidemic. Methods: We used a critical realist approach to thematic analysis, to examine quality in social interactions and underlying causes, …
Marginalization and Intersectionality in Adults' Relationship to Society Explain Increasing Loneliness
Loneliness epidemics affecting roughly 10% to 40% of adult populations do not have sufficient guidance for public health experts or governments to adequately address. To improve guidance, we developed an interdisciplinary approach to deepen explanation of underlying causes of loneliness using a critical realist lens. Using theory about social connection as a human basic need to frame our analysis, we first conducted thematic narrative inquiry to …
US Hospital Service Availability and New 340B Program Participation
The finding of the cohort study indicate that participation in the 340B program was associated with an increase in unprofitable services among newly participating public hospitals. Nonprofit hospitals were largely unaffected. These findings suggest that public hospitals responded to 340B savings by improving patient access, whereas nonprofits did not. This heterogeneous response should be considered when evaluating the eligibility criteria for th…
Enhancing Methodological Approaches for Studying Health Effects of High-Concentration THC Products
For public health protection, informed decision-making relies on having a robust foundation of evidence concerning risks and their prevention. Application of an evidence-based framework depends on the availability of pertinent, scientifically sound data generated by well-directed and valid research endeavors. In this essay, we address the current state of research in humans and the evidential base concerning high-concentration delta-9-tetrahydroc…
Health Effects of High-Concentration Cannabis Products
Background. The concentration of pharmacologically active tetrahydrocannabinol (THC) in cannabis products has been increasing over the past decade. Concerns about potential harmful health effects of using these increasingly higher-concentration products have led some states to consider regulation of cannabis product THC concentration. We conducted a scoping review of health effects of high-concentration cannabis products to inform policy on wheth…
Impact of cannabis legalization on healthcare utilization for psychosis and schizophrenia in Colorado
A qualitative study of effective collaboration among nurse home visitors, healthcare providers and community support services in the United States
Collaboration across sectors is needed to improve community health, but little is known about collaborative activities among public health prevention programs. Using the Nurse-Family Partnership® (NFP) home visiting program as context, this qualitative study aimed to describe effective collaboration among nurse home visitors, healthcare providers and community support services to serve families experiencing social and economic adversities. We use…
A case study of care co‐ordination between primary care providers and nurse home visitors to serve young families experiencing adversity in the Northwestern United States
Nurse home visitors in Nurse-Family Partnership® (NFP) work with mothers experiencing social and economic adversities to improve their and their children's health. Collaboration between nurse home visitors and primary care providers (PCPs: healthcare providers and social workers embedded within obstetrics, paediatrics and family medicine practices) can improve service delivery for families experiencing the greatest adversities. However, little is…
Risk assessment practices among home visiting nurses and child protection caseworkers in Colorado, United States
Nurses and caseworkers engage in assessments with the families they serve. Nurse home visitors from Nurse-Family Partnership (NFP) improve maternal-child health outcomes with first-time low-income mothers through care, education and support. In the United States, Child Protective Services (CPS) are state-level governmental agencies that protect children, including responding to reports of child maltreatment. This paper aimed to characterise simil…
Gun Retailers' Willingness to Provide Gun Storage for Suicide Prevention
Objectives: We examined factors grounded in the theory of planned behavior that influence gun retailers' willingness to provide temporary, voluntary firearm storage for suicide prevention. Methods: We conducted a cross-sectional survey of gun retailers in the US mountain west. Analyses included descriptive statistics and ordered logistic regression. Results: Ninety-five gun retailers responded to the survey (25% response rate) and 67.6% (95% CI: …
Law Enforcement and Gun Retailers as Partners for Safely Storing Guns to Prevent Suicide
Objectives. To examine the extent to which law enforcement agencies (LEAs) and gun retailers are willing to offer voluntary, temporary storage as a part of an overall suicide prevention effort. Methods. We invited all LEAs and gun retailers in 8 US states to respond to questionnaires asking about their willingness to offer temporary gun storage and their recommendations to gun owners about safe storage. Results. We collected data in 2016 from 448…
Political Factors Affecting the Enactment of State-Level Clean Indoor Air Laws
Objectives. We examined the effects of key political institutional factors on the advancement of state-level clean indoor air laws. Methods. We performed an observational study of state-level clean indoor air law enactment among all 50 US states from 1993 to 2010 by using extended Cox hazard models to assess risk of enacting a relevant law. Results. During the 18-year period from 1993 to 2010, 28 states passed a law covering workplaces, 33 states…
Creating Smoke-Free Places Through the UN Convention on the Rights of Persons With Disabilities
In some high-, middle-, and low-income countries, law has been employed to limit individuals’ secondhand smoke exposure. Innovative legal tools are still needed, especially in low- and middle-income countries where smoking prevalence continues to rise. For some persons with severe respiratory conditions, the presence of secondhand smoke is intolerable and prevents their entrance into restaurants and other venues. With its adoption of the Conventi…
Competing Initiatives
To describe how the tobacco and gaming industries opposed clean indoor air voter initiatives in 2006, we analyzed media records and government and other publicly available documents and conducted interviews with knowledgeable individuals. In an attempt to avoid strict “smoke free” regulations pursued by health groups via voter initiatives in Arizona, Ohio, and Nevada, in 2006, the tobacco and gaming industries sponsored competing voter initiative…
