INTRODUCTION/BACKGROUND:Tobacco smoke exposure (TSE) among individuals who do not smoke has declined in the USA, however, gaps remain in understanding how TSE patterns across indoor venues-including in homes, cars, workplaces, hospitality venues, and other areas-contribute to TSE disparities by income level. METHODS:We obtained data on adults (ages 18+, N=9909) and adolescents (ages 12-17, N=2065) who do not smoke from the National Health and Nutrition Examination Survey, 2013-2018. We examined the prevalence of self-reported, venue-specific TSE in each sample, stratified by poverty income ratio (PIR) quartile. We used linear regression models with a log-transformed outcome variable to explore associations between self-reported TSE and serum cotinine. We further explored the probability of detectable cotinine among individuals who reported no recent TSE, stratified by PIR. RESULTS:Self-reported TSE was highest in cars (prevalence=6.2% among adults, 14.2% among adolescents). TSE in own homes was the most strongly associated with differences in log cotinine levels (β for adults=1.92, 95% CI=1.52 to 2.31; β for adolescents=2.37 95% CI=2.07 to 2.66), and the association between home exposure and cotinine among adults was most pronounced in the lowest PIR quartile. There was an income gradient with regard to the probability of detectable cotinine among both adults and adolescents who did not report recent TSE. CONCLUSIONS:Homes and vehicles remain priority venues for addressing persistent TSE among individuals who do not smoke in the USA. TSE survey measures may have differential validity across population subgroups.

Medical mistrust as a construct often places the onus of blame for adverse health outcomes on individuals rather than on social structures. In this study, we aimed to determine if medical mistreatment and access to transgender care were potential determinants of medical mistrust. We used longitudinal survey data from 193 transgender women of colour living in New York City. We measured medical mistrust using the Group-Based Medical Mistrust (GBMM) scale. Additionally, we analysed and coded open-ended survey data from participants regarding their trust towards medical institutions to identify potential determinants of medical mistrust. From the quantitative analysis, we found that individuals who experienced mistreatment in healthcare and those who reported poor access to transgender care had higher GBMM scores. Qualitative findings suggested that negative experiences within the healthcare system and historical trauma were key factors contributing to mistrust in medical institutions. Addressing medical mistrust should not occur at the individual level, but rather at the structural level. Potential interventions include improving access to gender affirming care and training health professionals.

The degree to which alcohol use is associated with the risk of all-cause mortality and hepatic decompensation after hepatitis C (HCV) diagnosis, treatment, and cure remains unknown. We sought to address this question among patients achieving sustained virologic response (SVR) after direct-acting antiviral treatment in the largest HCV health system in the United States. We extracted data on alcohol use, HCV treatment, SVR, HIV co-infection, demographics, risk behaviours, hepatic decompensation, and mortality from all patients in the 1945 to 1965 VA Birth Cohort. Alcohol use categories were generated using responses to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questionnaire and diagnostic codes for alcohol use disorder (AUD): abstinent without a history of AUD, abstinent with a history of AUD, current lower-risk consumption, current moderate-risk consumption, and current high-risk consumption with or without AUD. Cox proportional hazard models were used to examine associations between alcohol category and the risk of hepatic decompensation and all-cause mortality. Among 50,581 patients in the analytic cohort, compared to current drinkers exhibiting lower risk alcohol consumption (referent), current high-risk consumption with or without AUD was associated with increased risk of all-cause mortality (aHR: 1.40, 95% CI: 1.21-1.63) and hepatic decompensation (HR: 2.15, 95% CI: 1.60-2.89) as was abstinence with a history of AUD diagnosis (mortality aHR: 1.63, 95% CI: 1.41-1.89; hepatic decompensation aHR: 1.85, 95% CI: 1.36-2.51). AUD and high-risk alcohol consumption are associated with the risk of hepatic decompensation and all-cause mortality among Veterans who have achieved SVR, including those categorised as being currently abstinent. Interventions for alcohol consumption and use disorder among individuals treated for HCV infection may reduce morbidity and mortality in this population.

Medical mistrust, clinical trial knowledge, and clinical trial risk impact research participation, yet are rarely studied among racial and ethnic groups. Data were from a cross-sectional survey (n = 1,794). Multinomial logistic regression models examined associations of medical mistrust, clinical trial knowledge, and clinical trial risk with willingness to participate in health research (Yes, No, Unsure) among Chinese, Korean, South Asian, Haitian, North American Latiné, South American Latiné, and Southwest Asian and North African (SWANA) NYC residents with one model per group. Overall, 46.0% of participants reported willingness to participate, ranging from 35.8% (Chinese participants) to 58.7% (South Asian participants). Increased mistrust was associated with less willingness among Chinese (OR: 1.06, 95%CI: 1.00, 1.12) and South American Latiné (OR: 1.15, 95%CI: 1.02, 1.30) participants; more willingness among Haitian participants (OR: 0.87, 95%CI: 0.81, 0.94); more uncertainty among Korean (OR: 1.13, 95%CI: 1.05, 1.22), South Asian (OR: 1.06 95%CI: 1.01, 1.12), and North American Latiné (OR: 1.18, 95%CI: 1.10, 1.28) participants; and less uncertainty among Haitian (OR: 0.91, 95%CI: 0.84, 0.99) and SWANA (OR: 0.91, 95%CI:0.86, 0.97) participants. Knowledge was associated with more willingness for Haitian participants (OR: 2.77, 95%CI: 1.15, 6.65), less willingness for Chinese participants (OR: 0.55, 95%CI: 0.34, 0.88), and more uncertainty among South Asian (OR: 2.09, 95%CI: 1.07, 4.07) and SWANA (OR: 2.71, 95%CI: 1.21, 6.03) participants. Some risk and more willingness were linked for South American Latiné participants (OR: 0.13, 95%CI: 0.02, 0.82). Associations varied by group. Studying multiple racial and ethnic groups advances equitable research representation.

BACKGROUND:The COVID-19 pandemic had a significant impact on healthcare delivery. Older adults with multimorbidities were at risk of healthcare disruptions for the management of their chronic conditions. OBJECTIVE:To characterize healthcare disruptions during the COVID-19 healthcare shutdown and recovery period (March 7, 2020-October 6, 2020) and their effects on disease management among older adults with multimorbidities who were patients of NYC Health + Hospitals (H + H), the largest municipal safety-net system in the United States. DESIGN/METHODS:Observational. PATIENTS/METHODS:Patients aged 50 + with hypertension or diabetes and at least one other comorbidity, at least one H + H ambulatory visit in the six months before COVID-19 pandemic onset (March 6, 2020), and at least one visit in the post-acute shutdown period (October 7, 2020 to December 31, 2023). MAIN MEASURES/METHODS:We characterized disruption in care (defined as no ambulatory or telehealth visits during the acute shutdown) and estimated the effect of disruption on blood pressure control, hemoglobin A1c (HbA1c), and low-density lipoprotein (LDL) cholesterol using difference-in-differences models. KEY RESULTS/RESULTS:Out of 73,889 individuals in the study population, 12.5% (n = 9,202) received no ambulatory or telehealth care at H + H during the acute shutdown. Low pre-pandemic healthcare utilization, Medicaid insurance, and self-pay were independent predictors of care disruption. In adjusted analyses, the disruption group had a 3.0-percentage point (95% CI: 1.2-4.8) greater decrease in blood pressure control compared to those who received care. Disruption did not have a significant impact on mean HbA1c or LDL. CONCLUSIONS:Care disruption was associated with declines in blood pressure control, which while clinically modest, could impact risk of cardiovascular outcomes if sustained. Disruption did not affect HbA1c or LDL. Telehealth mitigated impacts of the pandemic on care disruption and subsequent disease management. Targeted outreach to those at risk of care disruption is needed during future crises.

Transgender women of color (TWOC) are disproportionately impacted by psychological distress. Though gender-affirming care (GAC) has been recommended to alleviate this distress, research examining associations between perceived access to GAC, specific gender-affirming medical interventions (GAMIs), and mental health among TWOC in the United States remains limited. In this study, we examine cross-sectional and longitudinal associations between perceived access to GAC, completion of specific GAMIs, and psychological distress among TWOC, using modified Poisson regression and multilevel linear modeling. Data came from the Trying to Understand Relationships, Networks and Neighborhoods Among Transgender Women of Color (TURNNT) Cohort Study. In multivariable analyses, increased access to GAC was associated with reduced psychological distress risk. All assessed GAMIs suggested protective effects against psychological distress (aRR < 1), with statistical significance found for breast augmentation and facial feminization surgery. On average, those with unmet GAMI needs experienced higher distress risk than those without. Longitudinally, those experiencing reduced access to GAC over 6 months faced the highest distress risk among all trajectory groups (aRR: 1.40, 95% CI, 1.08-1.82). Our findings support the need for further inquiry in this area and suggest that policies protecting and increasing access to GAC may improve mental health among TWOC.

BACKGROUND:Community-clinical linkage models (CCLM) display significant potential to address the unique, multi-level type 2 diabetes risk factors facing minoritized communities, such as South Asian Americans. However, there lacks a systematic, longitudinal evaluation of how such tailored CCLMs can be better implemented in dynamic, real-world settings. This study aims to leverage multi-partner insights, collected in real time, to explore the barriers and facilitators to implement a South Asian American diabetes management and prevention intervention (the DREAM intervention). METHODS:The DREAM intervention, a two-arm randomized controlled trial, was implemented from 2019-2022; partners involved in its implementation were interviewed annually to understand their experiences of the program. Implementation partners included community health workers (CHWs), participating healthcare providers, community advisory board (CAB) partners, and research staff. The interview guide and subsequent deductive qualitative analysis was informed by the Consolidated Framework for Implementation Research (CFIR). RESULTS:Overall, 78 interviews were conducted across four waves (2019-2022) with 5 research staff, 8 CHWs, 18 providers/clinic staff, and 12 CAB partners. CHWs adapted intervention characteristics by tailoring curriculum and implementation to patient needs, including personalized goal setting and shifting to remote delivery with COVID-19-related content. At the individual level, participants' occupations, family dynamics, and technological capacity shaped engagement, while changing social, financial, and health contexts over time required CHWs to continually adjust support. Within the inner setting, partner roles and resource availability fluctuated, yet structured and consistent meetings facilitated communication and problem-solving. Outer setting influences, including shifting government and universities policies and the COVID-19 pandemic, required repeated adaptations, while CAB partnerships expanded community connections and services over time. Process-related findings underscored the evolving role of CHWs and research staff in planning and fidelity, with training shifting toward peer mentorship to build capacity. CONCLUSION/CONCLUSIONS:Findings revealed the pivotal role of programmatic adaptability and robust partner engagement in navigating dynamic contexts to support the diabetes needs of minoritized communities. The real-time, longitudinal approach taken for data collection and analysis was crucial in understanding how intervention changes were implemented and experienced, providing a model for similar implementation assessments.

BACKGROUND:levels. However, it remains unclear whether the CARE program also improves diabetes self-efficacy and psychosocial outcomes in the same study sample. OBJECTIVE:This is a secondary analysis to examine the potential efficacy of the CARE program on secondary outcomes, including diabetes self-efficacy, self-care activities, beliefs in diabetes self-care activities, and diabetes distress among Chinese Americans with T2D. METHODS:level of 7% or higher. Participants were recruited from various health care settings in New York City, including community health centers, private primary care providers, and NYU Langone Health and its affiliates, and were randomly assigned to either the CARE intervention group (n=30) or a waitlist control group (n=30). The intervention consisted of 2 culturally and linguistically tailored educational videos per week for 12 weeks, covering diabetes self-care topics such as healthy eating, physical activity, and medication adherence. These videos were delivered via the WeChat app. In addition, community health workers provided support calls to assist them in setting goals, problem-solving, and addressing social determinants of health barriers every 2 weeks. Secondary outcomes included patient self-reported diabetes self-efficacy, self-care activities, beliefs in diabetes self-care activities, and diabetes distress. Outcomes were assessed at baseline, 3 months, and 6 months. RESULTS:Participants had a mean age of 54.3 (SD 11.5) years and 62% (37/60) were male, 78% (47/60) were married, 58% (35/60) were employed, 70% (42/60) had a high school education or lower, and 88% (53/60) reported limited English proficiency. Intervention participants demonstrated statistically significant improvements in self-efficacy at 3 months (estimated difference in change: 8.47; 95% CI 2.44-14.5; adjusted P=.02), diabetes distress at 6 months (estimated difference in change: -0.43; 95% CI -0.71 to -0.15; adjusted P=.009), and adherence to a healthy diet at both 3 months (estimated difference in change: 1.61; 95% CI 0.46-2.75; adjusted P=.02) and 6 months (estimated difference in change: 1.64; 95% CI 0.48-2.81; adjusted P=.02). CONCLUSIONS:The culturally and linguistically tailored intervention showed promise in improving self-efficacy and diabetes self-care activities among Chinese Americans with T2D, warranting validation through a large-scale randomized controlled trial.
