Projecting the economic burden of health impacts of aircraft noise: a case study of Baltimore Washington International Thurgood Marshall Airport.

BACKGROUND: While the Next Generation Air Transportation System (NextGen) in the United States optimizes flight patterns, it has led to the unintended consequence of increasing aircraft noise exposure in some communities near airports. Despite the evidence that chronic exposure to high noise levels produces detrimental health effects, potential adverse health consequences due to increased noise in the affected communities have not been adequately considered in aviation policy discussions. OBJECTIVE: We assessed the long-term health and associated economic burden of increased aircraft noise caused by NextGen near the Baltimore-Washington Thurgood Marshall International (BWI) airport in Maryland. METHODS: A probabilistic Markov model projected the incremental health and associated economic burden over 30, 20, and 10 years, comparing post-NextGen noise exposure levels to pre-NextGen levels. Health outcomes included cardiovascular disease (CVD), anxiety disorders, noise annoyance, and low birth weight (LBW). Noise exposure was categorized into four levels (<55 dB DNL, 55-60 dB DNL, 60-65 dB DNL, >65 dB DNL). A Monte Carlo simulation with 2000 iterations was run to obtain incremental burden estimates and uncertainty intervals. One-way sensitivity analyses for noise effect parameters were conducted. RESULTS: Increased aircraft noise exposure was estimated to produce (discounted) incremental mortality costs of $362 million, morbidity costs of $336 million, and losses of 15,326 Quality-Adjusted Life Years (QALYs) over the next 30 years. Sensitivity analyses revealed the greatest uncertainty for CVD outcomes. IMPACT: NextGen is a system that can increase the operational efficiency of airports by optimizing flight patterns. While operational efficiency is beneficial in many ways, changes in flight patterns and volume can also produce noise pollution, a major public health concern that should be considered in policy decision-making. This study quantifies the long-term health and economic implications of increased aircraft noise exposure following the implementation of NextGen in communities near the Baltimore-Washington International Airport. Our findings underscore the importance of considering public health consequences of noise pollution.

Educational Mobility, Pace of Aging, and Lifespan Among Participants in the Framingham Heart Study.

Importance: People who complete more education live longer lives with better health. New evidence suggests that these benefits operate through a slowed pace of biological aging. If so, measurements of the pace of biological aging could offer intermediate end points for studies of how interventions to promote education will affect healthy longevity. Objective: To test the hypothesis that upward educational mobility is associated with a slower pace of biological aging and increased longevity. Design, Setting, and Participants: This prospective cohort study analyzed data from 3 generations of participants in the Framingham Heart Study: (1) the original cohort, enrolled beginning in 1948; (2) the Offspring cohort, enrolled beginning in 1971; and (3) the Gen3 cohort, enrolled beginning in 2002. A 3-generation database was constructed to quantify intergenerational educational mobility. Mobility data were linked with blood DNA-methylation data collected from the Offspring cohort in 2005 to 2008 (n = 1652) and the Gen3 cohort in 2009 to 2011 (n = 1449). Follow-up is ongoing. Data analysis was conducted from June 2022 to November 2023 using data obtained from the National Institutes of Health database of Genotypes and Phenotypes (dbGaP). Exposure: Educational mobility was measured by comparing participants' educational outcomes with those of their parents. Main Outcomes and Measures: The pace of biological aging was measured from whole-blood DNA-methylation data using the DunedinPACE epigenetic clock. For comparison purposes, the analysis was repeated using 4 other epigenetic clocks. Survival follow-up was conducted through 2019. Results: This study analyzed data from 3101 participants from the Framingham Heart Study; 1652 were in the Offspring cohort (mean [SD] age, 65.57 [9.22] years; 764 [46.2%] male) and 1449 were in the Gen3 cohort (mean [SD] age, 45.38 [7.83] years; 691 [47.7%] male). Participants who were upwardly mobile in educational terms tended to have slower pace of aging in later life (r = -0.18 [95% CI, -0.23 to -0.13]; P < .001). This pattern of association was similar across generations and held in within-family sibling comparisons. There were 402 Offspring cohort participants who died over the follow-up period. Upward educational mobility was associated with lower mortality risk (hazard ratio, 0.89 [95% CI, 0.81 to 0.98]; P = .01). Slower pace of aging accounted for approximately half of this association. Conclusions and Relevance: This cohort study's findings support the hypothesis that interventions to promote educational attainment may slow the pace of biological aging and promote longevity. Epigenetic clocks have potential as near-term outcome measures of intervention effects on healthy aging. Experimental evidence is needed to confirm findings.

The Effect of the Earned Income Tax Credit on Physical and Mental health-Results from the Atlanta Paycheck Plus Experiment.

Policy Points The Paycheck Plus randomized controlled trial tested a fourfold increase in the Earned Income Tax Credit (EITC) for single adults without dependent children over 3 years in New York and Atlanta. In New York, the intervention improved economic, mental, and physical health outcomes. In Atlanta, it had no economic benefit or impact on physical health and may have worsened mental health. In Atlanta, tax filing and bonus receipt were lower than in the New York arm of the trial, which may explain the lack of economic benefits. Lower mental health scores in the treatment group were driven by disadvantaged men, and the study sample was in good mental health. CONTEXT: The Paycheck Plus experiment examined the effects of an enhanced Earned Income Tax Credit (EITC) for single adults on economic and health outcomes in Atlanta, GA and New York City (NYC). The NYC study was completed two years prior to the Atlanta study and found mental and physical benefits for the subgroups that responded best to the economic incentives provided. In this article, we present the findings from the Atlanta study, in which the uptake of the treatment (tax filings and EITC bonus) were lower and economic and health benefits were not observed. METHODS: Paycheck Plus Atlanta was an unblinded randomized controlled trial that assigned n = 3,971 participants to either the standard federal EITC (control group) or an EITC supplement of up to $2,000 (treatment group) for three tax years (2017-2019). Administrative data on employment and earnings were obtained from the Georgia Department of Labor and survey data were used to examine validated measures of health and well-being. FINDINGS: In Atlanta, the treatment group had significantly higher earnings in the first project year but did not have significantly higher cumulative earnings than the control group overall (mean difference = $1,812, 95% CI = -150, 3,774, p = 0.07). The treatment group also had significantly lower scores on two measures of mental health after the intervention was complete: the Patient Health Questionnaire 8 (mean difference = 0.19, 95% CI = 0.06, 0.32, p = 0.005) and the Kessler 6 (mean difference = 0.15, 95% CI = 0.03, 0.27, p = 0.012). Secondary analyses suggested these results were driven by disadvantaged men, but the study sample was in good mental health. CONCLUSIONS: The EITC experiment in Atlanta was not associated with gains in earnings or improvements in physical or mental health.

Futureproofing Social Support Policies for Population Health.

Policy Points In America, wages appear to be growing relative to purchasing power over time. However, while the ability to purchase consumer goods has indeed improved, the cost of basic survival needs such as health care and education has increased faster than wages have grown. America's weakening social policy landscape has led to a massive socioeconomic rupture in which the middle class is disappearing, such that most Americans now cannot afford basic survival needs, such as education and health insurance. Social policies strive to rebalance societal resources from socioeconomically advantaged groups to those in need. Education and health insurance benefits have been experimentally proven to also improve health and longevity. The biological pathways through which they work are also understood.

Willingness-to-pay tuition and risk-taking proclivities among public health students.

Objective: To quantify students' risk tolerance for in-person classes and willingness-to-pay for online-only instruction during the COVID-19 pandemic. Participants: 46 Columbia University public health graduate students. Methods: We developed a survey tool with a "standard gamble" exercise administered online by an interactive chat bot with full anonymity by students. Students were asked to trade between the risk of infection with COVID-19 and: (1) attending classes in-person, and (2) attending community parties. We also assessed willingness-to-pay for online-only tuition. Results: Students accepted a 23% (standard error [SE]: 4%) risk of infection to attend classes in-person and 15% of them expressed willingness to attend community parties even if the COVID-19 prevalence were high. Students were willing-to-pay only 48% (SE: 3%) of the regular, in-person tuition fees for online instruction. Conclusions: Public health students with a strong knowledge of COVID-19 transmission were willing to accept a significant risk of infection for in-person instruction.Trial registration:NA.

Self-reported anxiety and depression problems and suicide ideation among black and latinx adults and the moderating role of social support.

Suicide is a critical public health problem. Over the past decade, suicide rates have increased among Black and Latinx adults in the U.S. Though depression is the most prevalent psychiatric contributor to suicide risk, Black and Latinx Americans uniquely experience distress and stress (e.g., structural adversity) that can independently operate to worsen suicide risk. This makes it important to investigate non-clinical, subjective assessment of mental health as a predictor of suicide ideation. We also investigate whether social support can buffer the deleterious impact of poor mental health on suicide ideation.We analyzed data from 1,503 Black and Latinx participants of the Washington Heights Community Survey, a 2015 survey of residents of a NYC neighborhood. Multivariable logistic regression was conducted to examine the effect of subjectively experienced problems with anxiety and depression on suicide ideation independent of depression diagnosis, and the role of social support as a moderator.Estimated prevalence of past two-week suicide ideation was 5.8%. Regression estimates showed significantly increased odds of suicide ideation among participants reporting moderate (OR = 8.54,95% CI = 2.44-29.93) and severe (OR = 16.84,95% CI = 2.88-98.46) versus no problems with anxiety and depression, after adjustment for depression diagnosis. Informational support, i.e., having someone to provide good advice in a crisis, reduced the negative impact of moderate levels of anxiety and depression problems on suicide ideation.Findings suggest that among Black and Latinx Americans, subjective feelings of anxiety and depression account for a significant portion of the suicide ideation risk related to poor mental health. Further, social support, particularly informational support, may provide protection against suicide ideation.

The relationship between voting restrictions and COVID-19 case and mortality rates between US counties.

BACKGROUND: Since the 2010 election, the number of laws in the U.S. that create barriers to voting has increased dramatically. These laws may have spillover effects on population health by creating a disconnect between voter preferences and political representation, thereby limiting protective public health policies and funding. We examine whether voting restrictions are associated with county-level COVID-19 case and mortality rates. METHODS: To obtain information on restricted access to voting, we used the Cost of Voting Index (COVI), a state-level measure of barriers to voting during a U.S. election from 1996 to 2016. COVID-19 case and mortality rates were obtained from the New York Times' GitHub database (a compilation from multiple academic sources). Multilevel modeling was used to determine whether restrictive voting laws were associated with county-level COVID-19 case and mortality rates after controlling for county-level characteristics from the County Health Rankings. We tested whether associations were heterogeneous across racial and socioeconomic groups. RESULTS: A significant association was observed between increasing voting restrictions and COVID-19 case (ß = 580.5, 95% CI = 3.9, 1157.2) and mortality rates (ß = 16.5, 95% CI = 0.33,32.6) when confounders were included. CONCLUSIONS: Restrictive voting laws were associated with higher COVID-19 case and mortality rates.

The cost-effectiveness of standalone HEPA filtration units for the prevention of airborne SARS CoV-2 transmission.

OBJECTIVE: Airborne infection from aerosolized SARS-CoV-2 poses an economic challenge for businesses without existing heating, ventilation, and air conditioning (HVAC) systems. The Environmental Protection Agency notes that standalone units may be used in areas without existing HVAC systems, but the cost and effectiveness of standalone units has not been evaluated. STUDY DESIGN: Cost-effectiveness analysis with Monte Carlo simulation and aerosol transmission modeling. METHODS: We built a probabilistic decision-analytic model in a Monte Carlo simulation that examines aerosol transmission of SARS-CoV-2 in an indoor space. As a base case study, we built a model that simulated a poorly ventilated indoor 1000 square foot restaurant and the range of Covid-19 prevalence of actively infectious cases (best-case: 0.1%, base-case: 2%, and worst-case: 3%) and vaccination rates (best-case: 90%, base-case: 70%, and worst-case: 0%) in New York City. We evaluated the cost-effectiveness of improving ventilation rate to 12 air changes per hour (ACH), the equivalent of hospital-grade filtration systems used in emergency departments. We also provide a customizable online tool that allows the user to change model parameters. RESULTS: All 3 scenarios resulted in a net cost-savings and infections averted. For the base-case scenario, improving ventilation to 12 ACH was associated with 54 [95% Credible Interval (CrI): 29-86] aerosol infections averted over 1 year, producing an estimated cost savings of $152,701 (95% CrI: $80,663, $249,501) and 1.35 (95% CrI: 0.72, 2.24) quality-adjusted life years (QALYs) gained. CONCLUSIONS: It is cost-effective to improve indoor ventilation in small businesses in older buildings that lack HVAC systems during the pandemic.

Impact of aeroplane noise on mental and physical health: a quasi-experimental analysis.

OBJECTIVES: Historically, departures at New York City's LaGuardia airport flew over a large sports complex within a park. During the US Open tennis games, flights were diverted to fly over a heavily populated foreign-born neighbourhood for roughly 2 weeks out of the year so that the tennis match was not disturbed (the 'TNNIS' departure). In 2012, the use of the TNNIS departure became year-round to better optimise flight patterns around the metropolitan area. METHODS: We exploited exogenously induced spatial and temporal variation in flight patterns to examine difference-in-difference effects of this new exposure to aircraft noise on the health of individual residents in the community relative to individuals residing within a demographically similar community that was not impacted. We used individual-level Medicaid records, focusing on conditions associated with noise: sleep disturbance, psychological stress, mental illness, substance use, and cardiovascular disease. RESULTS: We found that increased exposure to aeroplane noise was associated with a significant increase in insomnia across all age groups, but particularly in children ages 5-17 (OR=1.64, 95% CI=1.12 to 2.39). Cardiovascular disease increased significantly both among 18-44-year-old (OR=1.45, 95% CI=1.41 to 1.49) and 45-64-year-old Medicaid recipients (OR=1.15, 95% CI=1.07 to 1.25). Substance use and mental health-related emergency department visits also increased. For ages 5-17,rate ratio (RR) was 4.11 (95% CI=3.28 to 5.16); for ages 18-44, RR was 2.46 (95% CI=2.20 to 2.76); and for ages 45-64, RR was 1.48 (95% CI=1.31 to 1.67). CONCLUSION: We find that increased exposure to aeroplane noise was associated with an increase in diagnosis of cardiovascular disease, substance use/mental health emergencies and insomnia among local residents.

Social mobility and biological aging among older adults in the United States.

Lower socioeconomic status is associated with faster biological aging, the gradual and progressive decline in system integrity that accumulates with advancing age. Efforts to promote upward social mobility may, therefore, extend healthy lifespan. However, recent studies suggest that upward mobility may also have biological costs related to the stresses of crossing social boundaries. We tested associations of life-course social mobility with biological aging using data from participants in the 2016 Health and Retirement Study (HRS) Venous Blood Study who provided blood-chemistry (n = 9,255) and/or DNA methylation (DNAm) data (n = 3,976). We quantified social mobility from childhood to later-life using data on childhood family characteristics, educational attainment, and wealth accumulation. We quantified biological aging using 3 DNAm "clocks" and 3 blood-chemistry algorithms. We observed substantial social mobility among study participants. Those who achieved upward mobility exhibited less-advanced and slower biological aging. Associations of upward mobility with less-advanced and slower aging were consistent for blood-chemistry and DNAm measures of biological aging, and were similar for men and women and for Black and White Americans (Pearson-r effect-sizes ∼0.2 for blood-chemistry measures and the DNAm GrimAge clock and DunedinPoAm pace-of-aging measures; effect-sizes were smaller for the DNAm PhenoAge clock). Analysis restricted to educational mobility suggested differential effects by racial identity; mediating links between educational mobility and healthy aging may be disrupted by structural racism. In contrast, mobility producing accumulation of wealth appeared to benefit White and Black Americans equally, suggesting economic intervention to reduce wealth inequality may have potential to heal disparities in healthy aging.

Neighborhood disparities in COVID-19 outcomes in New York city over the first two waves of the outbreak.

PURPOSE: To assess the association of neighborhood demographic and socioeconomic characteristics with COVID-19 incidence and mortality in New York City (NYC) over the first two waves of outbreak. METHODS: This retrospective study used neighborhood-level data from 177 modified ZIP code tabulation areas in NYC between March 01, 2020 and April 30, 2021. RESULTS: Neighborhoods that were most severely impacted in wave 1 were also more affected in wave 2. Neighborhoods with a higher percentage of seniors (≥75 years), males, Black and Hispanic population, and large-size households had higher incidence rates of COVID-19 in wave 1 but not in wave 2. Neighborhoods with higher percentage of Black and Hispanic population and lower insurance coverage had higher death rate per capita and case fatality ratio in wave 1, and neighborhoods with higher percentage of Black and Asian population had elevated case fatality ratio in wave 2. Median household income was negatively associated with incidence rate and death rate per capita but not associated with case fatality ratio in both waves. Neighborhoods with more seniors had higher death rate and case fatality ratio in both waves. CONCLUSIONS: Neighborhood disparities in COVID-19 incidence and mortality across NYC neighborhoods were dynamic during the first two waves of outbreak.

Medicaid Social Risk Adjustment in Oregon: Perspectives from Stakeholders.

Health care providers are often evaluated on patient health outcomes and quality of care measures. The social determinants of health play an outsized role in determining patient outcomes regardless of the quality of care delivered. As a result, providers caring for poor and underserved patients tend to receive lower value-adjusted payments, which exacerbates disparities in access to care. We conducted semi-structured interviews with 30 researchers, health policy constituents, and Medicaid payer and practice leaders in Oregon to better assess how to use social factors in risk adjustment modeling. While all 30 respondents agreed with the importance of social risk adjustment, we find that the experts have divergent perspectives on how to approach individual and community social risk. Moreover, many respondents felt dismayed because the data required are plagued by fragmentation and outdated privacy protection frameworks. Our findings suggest that alternative payment models must be better developed for low-income and underserved communities.

Effect of Expanding the Earned Income Tax Credit to Americans Without Dependent Children on Psychological Distress.

Antipoverty policies have the potential to improve mental health. We conducted a randomized trial (Paycheck Plus Health Study Randomized Controlled Trial, New York, New York) to investigate whether a 4-fold increase in the Earned Income Tax Credit for low-income Americans without dependent children would reduce psychological distress relative to the current federal credit. Between 2013 and 2014, a total of 5,968 participants were recruited; 2,997 were randomly assigned to the treatment group and 2,971 were assigned to the control group. Survey data were collected 32 months postrandomization (n = 4,749). Eligibility for the program increased employment by 1.9 percentage points and after-bonus earnings by 6% ($635/year), on average, over the 3 years of the study. Treatment was associated with a marginally statistically significant decline in psychological distress, as measured by the 6-item Kessler Psychological Distress Scale, relative to the control group (score change = -0.30 points, 95% confidence interval (CI): -0.63, 0.03; P = 0.072). Women in the treated group experienced a half-point reduction in psychological distress (score change = -0.55 points, 95% CI: -0.97, -0.13; P = 0.032), and noncustodial parents had a 1.36-point reduction (95% CI: -2.24, -0.49; P = 0.011). Expansion of a large antipoverty program to individuals without dependent children reduced psychological distress for women and noncustodial parents-the groups that benefitted the most in terms of increased after-bonus earnings.

Financial Barriers to Mental Healthcare Services and Depressive Symptoms among Residents of Washington Heights, New York City.

Objectives: In the United States, Hispanics are more likely to experience financial barriers to mental health care than non-Hispanics. We used a unique survey to study the effect of these financial barriers on the severity of depressive symptoms among Hispanics who had previously been diagnosed as having depression. Methods: This cross-sectional study used data from the 2015 Washington Heights Community Survey, administered to 2,489 households in Manhattan, New York City. Multiple regression models and propensity score matching were used to estimate the association between financial barriers to mental health care and depressive symptoms and the likelihood of being clinically depressed. Results: Among those diagnosed with depression, those with financial barriers to mental health services or counseling had significantly higher (ß = 0.36, 95% CI = 0.03, 0.70) depressive symptoms. When propensity score matching was utilized, those with financial barriers to mental health services had significantly greater depressive symptoms (ß = 0.63, 95% CI = 0.37, 0.89) and were significantly more likely to be currently depressed (OR = 2.38, 95% CI = 1.46, 3.89), in comparison to those who had access. Conclusions: Making mental health care more affordable and therefore more accessible to Hispanics is one step toward mitigating the burden on mental illness and decreasing health disparities.

The cost-effectiveness of common strategies for the prevention of transmission of SARS-CoV-2 in universities.

BACKGROUND: Most universities that re-open in the United States (US) for in-person instruction have implemented the Centers for Disease Prevention and Control (CDC) guidelines. The value of additional interventions to prevent the transmission of SARS-CoV-2 is unclear. We calculated the cost-effectiveness and cases averted of each intervention in combination with implementing the CDC guidelines. METHODS: We built a decision-analytic model to examine the cost-effectiveness of interventions to re-open universities. The interventions included implementing the CDC guidelines alone and in combination with 1) a symptom-checking mobile application, 2) university-provided standardized, high filtration masks, 3) thermal cameras for temperature screening, 4) one-time entry ('gateway') polymerase chain reaction (PCR) testing, and 5) weekly PCR testing. We also modeled a package of interventions ('package intervention') that combines the CDC guidelines with using the symptom-checking mobile application, standardized masks, gateway PCR testing, and weekly PCR testing. The direct and indirect costs were calculated in 2020 US dollars. We also provided an online interface that allows the user to change model parameters. RESULTS: All interventions averted cases of COVID-19. When the prevalence of actively infectious cases reached 0.1%, providing standardized, high filtration masks saved money and improved health relative to implementing the CDC guidelines alone and in combination with using the symptom-checking mobile application, thermal cameras, and gateway testing. Compared with standardized masks, weekly PCR testing cost $9.27 million (95% Credible Interval [CrI]: cost-saving-$77.36 million)/QALY gained. Compared with weekly PCR testing, the 'package' intervention cost $137,877 (95% CrI: $3,108-$19.11 million)/QALY gained. At both a prevalence of 1% and 2%, the 'package' intervention saved money and improved health compared to all the other interventions. CONCLUSIONS: All interventions were effective at averting infection from COVID-19. However, when the prevalence of actively infectious cases in the community was low, only standardized, high filtration masks clearly provided value.

Perceived Discrimination and Increased Odds of Unmet Medical Needs Among US Children.

Our study examines the association between perceived discrimination due to race and unmet medical needs among a nationally representative sample of children in the United States. We used data from the 2016-2017 National Survey of Children's Health, a population-based cross-sectional survey of randomly selected parents or guardians in the United States. We compared results from the coarsened exact matching (CEM) method and survey-weighted logistic regression to assess the robustness of the results. Using self-reported measures from caregivers, we find that ∼2.7% of US children have experienced racial discrimination with prevalence varying significantly by race. While <1% of non-Hispanic whites have experienced some measure of racism, this increases to 8.8% among non-Hispanic blacks. Perceived discrimination was associated with significantly greater odds of unmet medical needs in the adjusted, survey-weighted multivariate-adjusted model (adjusted odds ratio [OR] = 2.4 and 95% confidence interval [CI] = 1.2, 4.9) as well as in the CEM-model estimate (OR = 2.8 and 95% CI = 1.8, 4.0). Children who have experienced perceived discrimination had higher odds of unmet medical needs. Awareness of discrimination among children may help inform future intervention development that addresses unmet medical needs during childhood.

Psychological Distress Among the First Quarantined Community in the United States: Initial Observations From the Early Days of the COVID-19 Crisis.

This study assesses distress and anxiety symptoms associated with quarantine due to COVID-19 exposure among the first quarantined community in the United States and identifies potential areas of intervention. All participants were directly or peripherally related to "patient 1,"-the first confirmed community-acquired case of COVID-19 in the New York Area. As such, this is a historically significant sample whose experiences highlight a transitional moment from a pre-pandemic to a pandemic period in the United States. In March 2020, an anonymous survey was distributed to 1,250 members of a NYC area community that was under community-wide quarantine orders due to the COVID-19 outbreak. Distress was measured using the Subjective Units of Distress Scale (SUDS) and symptoms of anxiety were measured using the Beck Anxiety Inventory (BAI). A variety of psychosocial predictors relevant to the current crisis were explored. Three hundred and three individuals responded within forty-eight hours of survey distribution. Mean levels of distress in the sample were heightened and sustained, with 69% reporting moderate to severe distress on the SUDS and 53% of the sample reported mild, moderate, or severe anxiety symptoms on the BAI. The greatest percentage of variance of distress and anxiety symptoms was accounted for by modifiable factors amenable to behavioral and psychological interventions.
