PURPOSE: Indicators of poor mental health increased during the COVID-19 pandemic among emerging adults aged 18-24 years, a group already at elevated risk. This study explores associations between contextual and personal stressors with symptoms of emerging adults' anxiety and depression, assessing both multidimensional and distinct measures of stress. METHODS: Using Census Household Pulse Surveys from emerging adults aged 18 to 24 years (N = 71,885) and administrative data from April 23, 2020 to March 29, 2021, we estimated logistic regression models adjusted for state and wave fixed effects. RESULTS: Rates of elevated anxiety and depressive symptoms rose dramatically among emerging adults during the first year of the COVID-19 pandemic. Results indicate that potential contextual stressors-state COVID-19 rates and state COVID-19 mitigation policies limiting social interactions (stay-at-home orders, restaurant closures, large gathering restrictions, and mask mandates)-were not significantly associated with symptoms. In contrast, personal economic stressors (nonemployment, household income loss, food insecurity, housing insecurity, lacking health insurance) and disruptions to education were associated significantly with elevated anxiety and depressive symptoms, with greater numbers of stressors associated with worse well-being. DISCUSSION: Emerging adults reported persistently high levels of elevated anxiety and depressive symptoms during the first year of the pandemic, outcomes associated not with COVID-19 rates or mitigation policies, but with economic inequities, and other personal stressors heightened by the pandemic. Providing targeted support for young adults, including ensuring access to mental health supports, health care, and economic relief, is critical.

BACKGROUND: States have recently enacted tobacco-related age and flavour restrictions in addition to federal T21 laws. Little is known about the independent effects of these policies on young adult tobacco use. METHODS: Linking 2011-2022 Behavioural Risk Factor Surveillance System data on 2 696 870, 18-59 years from 50 states and DC with policy data, we conducted probit regression models to evaluate the associations between state and federal T21 laws and state flavour restrictions with cigarettes, electronic nicotine delivery system (ENDS) and smokeless tobacco use. Models were adjusted for sociodemographics, additional tobacco policies, COVID-19-related factors, year and state. We tested two-way and three-way interactions between age, state T21 and federal T21 laws. RESULTS: Although we did not find evidence that state T21 laws were associated with cigarette, smokeless tobacco or ENDS use overall, the federal T21 law was associated with lower use of all three tobacco products by 0.39-0.92 percentage points. State flavour restrictions were associated with lower use of cigarettes by 0.68 (-1.27 to -0.09) and ENDS by 0.56 (-1.11 to -0.00) percentage points, but not with smokeless tobacco. A three-way interaction revealed that state and federal T21 laws together were associated with a lower prevalence of ENDS use among 18-20 years, but there were no differences in cigarette use from both policies combined versus either alone. CONCLUSION: State and federal T21 laws are broadly effective at reducing adult tobacco use, while state flavour restrictions specifically lower use of cigarettes and ENDS.
RESUMO
OBJECTIVE: The aim of the study is to examine the associations between mandatory access prescription drug monitoring programs (PDMPs), pain management clinic (PMC) laws, and doctor shopping (DS) laws with adolescent nonmedical use of prescription medications (NUPM). METHODS: We linked 2011-2015 Youth Risk Behavior Survey data on 364,103 adolescents across 40 states with PDMP, PMC laws, and DS laws. We conducted a 2-way fixed effects logistic regression model to examine the associations between state drug laws and adolescent self-reported NUPM. RESULTS: We found some evidence that implementation of a mandatory access PDMP was associated with a decrease in nonmedical use of prescription drugs at the P = 0.079 level (average marginal effect: -0.017, 95% confidence interval = -0.036 to 0.002), while there were no associations with the implementation of PMC and DS laws. CONCLUSIONS: Our findings suggest that current state drug laws to combat NUPM are inadequate for adolescents.

RATIONALE: The COVID-19 pandemic led to dramatic increases not only in physical illness, but also in mental health symptoms and disorders among U.S. adults. Although the introduction of COVID-19 vaccines dramatically lowered rates of physical illness and death, little is known about the effects of vaccines on mental health. OBJECTIVES: We assessed both individual and spillover effects of COVID-19 vaccination on mental health disorders, and whether effects of individual vaccination varied based on contextual risks indicated by state infection rates and state vaccination rates. METHODS: Using data from the Household Pulse Survey, we assessed 448,900 adults surveyed within approximately the first six months of the U.S. vaccine rollout (February 3 - August 2, 2021). Coarsened exact matching balanced vaccinated and non-vaccinated participants on demographic and economic characteristics. RESULTS: Logistic regression analyses found 7% lowered odds of depression among vaccinated individuals, but no significant difference in anxiety. Reflecting potential spillover effects, state vaccination rates predicted lowered odds of anxiety and depression (1% decrease in odds for each additional 1% of the state population vaccinated). Although state COVID-19 infection rates did not moderate effects of individual vaccination on mental health outcomes, significant interactions indicated that effects of individual vaccination on mental health were stronger in contexts of lower state vaccination rates, and links between state vaccination rates and mental health problems were stronger among unvaccinated individuals. CONCLUSIONS: Results suggest that COVID-19 vaccinations improved the mental health of adults in the U.S., with lower rates of self-reported mental health disorders both among vaccinated individuals themselves and among other individuals living in the same state, particularly when those individuals were not themselves vaccinated. These direct and spillover effects on mental health expand our understanding of the benefits of COVID-19 vaccination for the wellbeing of adults in the U.S.

Background: Tobacco control policies have been adapted to address rising levels of adolescent e-cigarette use. Despite new restrictions, adolescents are continuing to access e-cigarettes. Methods: We linked 2015-2019 Youth Risk Behavior Survey data on 503,154 14-18-year-olds from 40 states with state-level e-cigarette minimum legal sales age (MLSA) laws, taxes, and smoke-free legislation. Using two-way fixed effects probit regression models, we first examined the associations between these statewide e-cigarette policies and adolescent use and, second, with access to e-cigarettes. We subsequently tested interactions between age and each policy and present average marginal effects as percentage point (pp) changes. Results: While MLSA laws for e-cigarettes were associated with slight increases in e-cigarette use (2.72 pp; 1.29, 4.15), associations were no longer significant after at least 1-year post-implementation. MLSA laws were also associated with decreases in e-cigarette purchases in stores (-9.50 pp; -18.21, -0.79) and increases in acquiring them from someone else (13.26 pp; 4.10, 22.42), particularly among 18-year-olds. E-cigarette taxes were associated with decreases in use (-9.18 pp; -11.63, -6.73), but there were limited associations with e-cigarette access. While smoke-free legislation prohibiting e-cigarettes was associated with slight increases in use (1.87 pp; 0.23, 3.50), after at least 1-year post-implementation, they were associated with decreases in use. Smoke-free legislation was also associated with decreases in purchases in stores by 14-year-olds, but increases in online purchases by 18-year-olds. Conclusion: Understanding the immediate and longer-term consequences of e-cigarette policies is essential to influence adolescent e-cigarette use. Adolescents will continue acquiring e-cigarettes across varying sources if measures are not taken to address access alongside policies aimed at reducing use.
RESUMO
Objectives. To examine the impact of school shootings on indicators of adolescent school safety in the United States. Methods. We linked 2009-2019 Youth Risk Behavior Survey data on 211 236 adolescents aged 14 to 18 years from 24 school districts with data on high school shootings from the Center for Homeland Defense and Security. We conducted 2-way fixed-effects logistic regression models to assess the impact of shootings on self-report of 3 indicators of school safety: avoiding school because of feeling unsafe, carrying a weapon at school, and being threatened or injured with a weapon at school. Results. High school shootings were associated with adolescents having 20% greater odds of avoiding school because of feeling unsafe (adjusted odd ratio [AOR] = 1.20; 95% confidence interval [CI] = 1.11, 1.29) than those who had not. Findings were slightly attenuated in sensitivity analyses that tested exposure to shootings at any school in the district or state. High school shootings were associated with a statistically nonsignificant (P = .08) elevated risk of carrying a weapon at school (AOR = 1.11; 95% CI = 0.99, 1.25). Conclusions. The negative ramifications of school shootings extend far beyond the event itself to adolescents' concerns about school safety.

Despite mounting evidence on the health effects of natural gas development (NGD), including hydraulic fracturing ("fracking"), existing research has been constrained to high-producing states, limiting generalizability. To expand the scope of previous research, we examined the associations between prenatal exposure and NGD production activity in 28 states on birth outcomes overall and by race/ethnicity. We linked 2005-2018 county-level microdata natality files on 33,849,409 singleton births from 1984 counties in 28 states with nine-month county-level averages of NGD production by both conventional and unconventional production methods, based on month/year of birth. We estimated linear regression models for birth weight and gestational age and probit models for the dichotomous outcomes of low birth weight, preterm birth, and small-for-gestational age. We subsequently examined interactions between women's race/ethnicity and NGD production. We found that 53.8% of counties had NGD production activity. A 10% increase in NGD production in a county was associated with a decrease in mean birth weight by 1.48 g (95% CI = -2.60, -0.37), with reductions of 10.19 g (-13.56, -6.81) for infants born to Black women and 2.76 g (-5.05, -0.46) for infants born to Asian women. A 10% increase in NGD production in a county was associated with an increased risk of infants born low birth weight (0.0008; 95% CI = 0.0006, 0.0010) or small-for-gestational age (0.0018; 95% CI = 0.0015, 0.0022), particularly among infants born to Black women. In sum, NGD for energy production has negative impacts on the health of infants, with greatest effects in infants born to minoritized women.
RESUMO
OBJECTIVES: The COVID-19 pandemic has led to severe mental health repercussions. We examined rates of anxiety and depression in the United States during the pandemic by demographic characteristics, individual stressors, and COVID-19 infection rates and policy contexts. METHODS: We merged data from the April 2020-March 2021 US Household Pulse Survey with state-level data on COVID-19 rates and mitigation policies, including stay-at-home orders, face mask mandates, and restaurant closures. We estimated weighted logistic regression models to assess correlates of anxiety and depression. RESULTS: Rates of anxiety and depression peaked in late 2020 at 39% and 32%, respectively. Food insecurity and disrupted medical care were associated with more than twice the odds of anxiety and depression (food insecurity: odds ratio [OR] = 2.58 for anxiety and 2.61 for depression; disrupted medical care: OR = 2.40 and 2.27). Being not employed (OR = 1.32 for anxiety and 1.45 for depression), uninsured (OR = 1.30 and 1.38), housing insecure (OR = 1.41 and 1.34), and experiencing disruptions in education (OR = 1.28 and 1.25) were linked to 25% to 45% increased odds of anxiety and depression. Increases in state COVID-19 infection rates were associated with significantly heightened odds of anxiety and depression (OR = 1.01 for anxiety and depression), but state mitigation policies were not. CONCLUSIONS: Levels of anxiety and depression rose during the pandemic, particularly among economically vulnerable individuals and those experiencing economic and service disruptions. Future research should assess the effectiveness of policies targeting COVID-19 economic and service disruptions.

BACKGROUND: There have been long-standing debates about the potential health consequences of hate crimes over and above other types of crimes. Besides the direct consequences for victims, less is known about whether hate crimes have spillover effects onto the health of local residents. METHODS: We drew data on cardiovascular disease risk factors from middle-aged Americans in the National Longitudinal Survey of Youths 1979 and on hate crimes from the FBI's Uniform Crime Reports. Employing multivariable logistic regression, we estimated the associations between changes in state/county-level all and group-specific hate crime rates from 2000 to 2006 and incident individual-level diabetes, hypertension, obesity and depressive symptoms from 2008 to 2016. All models controlled for individual-level sociodemographic factors and financial strain, county-level and state-level changes in the total crime rate, the percentage of non-Hispanic Black and Hispanic/Latino residents, and median household income, as well as state-level changes in the percentage of residents aged 65 years or older and the unemployment rate. RESULTS: 1-SD increases in state-level all and race/ethnicity-based hate crime rates were associated with 20% (OR 1.20, 95% CI 1.05 to 1.35) and 15% higher odds (OR 1.15, 95% CI 1.01 to 1.31) of incident diabetes, respectively. At the county level, a 1-SD increase in the all hate crime rate was linked to 8% higher odds (OR 1.08, 95% CI 1.00 to 1.16) of obesity, while a 1-SD increase in the race/ethnicity-based hate crime rate was associated with 8% higher odds (OR 1.08, 95% CI 1.01 to 1.15) of obesity and 9% higher odds (OR 1.09, 95% CI 1.02 to 1.17) of hypertension. We found no significant associations for depressive symptoms, and no interactions between race/ethnicity-based hate crime rates and individual-level race/ethnicity. CONCLUSION: Living in areas with higher hate crime rates may confer higher odds of hypertension, diabetes and obesity.

BACKGROUND: The Patient Protection and Affordable Care Act (ACA) required new private insurance plans to provide breast pumps with no cost sharing beginning August 2012, and in January 2014 expanded this requirement to Marketplace plans and expanded Medicaid coverage. We first examined the associations between the ACA reforms in 2012 and 2014 with rates of breast pump claims between Medicaid enrollees and those with private insurance. We next examined the associations between the monthly rate of breast pump claims with breastfeeding initiation and duration by insurance type. METHODS: Using 2011-2015 public and private health insurance claims in All-Payer Claims Databases from Massachusetts, Maine, and New Hampshire, we conducted a linear regression model to evaluate the associations between the 2012 and 2014 ACA health insurance reforms with rates of breast pump claims by health insurance status. We then linked the monthly rates of breast pump claims per 1,000 live births to the Pregnancy Risk Assessment Monitoring System with self-reported breastfeeding initiation and duration. We estimated probit regression models to examine the associations between monthly rates of breast pump claims per state, insurance type, age group, and breastfeeding outcomes. RESULTS: For the 2012 ACA reform, breast pump claims increased by 183.4 (143.7-223.1) per 1,000 live births for women with private insurance, but decreased for Medicaid enrollees (-99.3 [-139.0 to -59.6]). For the 2014 ACA reforms, the opening of health insurance Marketplaces had no effect on breast pump claims for women with private insurance (8.3 [-43.6 to 60.2]), whereas Medicaid expansion increased claims by 119.4 (67.5-171.3) per 1,000 live births for Medicaid enrollees. Every additional 10 breast pump claims per 1,000 live births was associated with a 1.08 percentage point increase in breastfeeding initiation among women with private insurance (0.108 [0.018-0.198]), but not Medicaid enrollees (0.076 [-0.078 to 0.230]). In contrast, every additional 10 breast pump claims per 1,000 live births was associated with a 1.79 percentage point increase in breastfeeding for 4 or more weeks for women with private insurance (0.179 [0.063-0.294]) and a 2.05 percentage point increase among women with public insurance (0.205 [0.033-0.376]). Interaction analysis revealed no significant differences in associations by insurance type across breastfeeding outcomes. CONCLUSIONS: The ACA breastfeeding coverage requirements fill a gap for women wanting to obtain a breast pump to support breastfeeding. The monthly rate of breast pump claims, as an indicator of access, translated into higher levels of breastfeeding for women with private and public insurance with the potential to reduce socioeconomic disparities.

The COVID-19 pandemic has led to rising morbidity, mortality, and social and economic disruption, likely impairing mental health. The purpose of this study was to track trends in mental health symptoms, use of services, and unmet need for services among US adults, and to delineate variation across demographic strata. Data were drawn from the 2020 US Household Pulse Survey from repeated cross-sectional online surveys collected between April 23 and November 23, 2020 from 1,302,455 US adults, weighted to represent the US population. Survey respondents self-reported their symptoms of anxiety and depression, use of medication and counseling services, and unmet need for services. Reports of probable anxiety and depression rose significantly through the study period, to prevalence rates of 37% and 29%, respectively, by November, 2020, rates more than four times higher than early 2019 US norms. Use of prescription medication, counseling services, and unmet need for mental health services also rose significantly. Prevalence rates of probable mental health disorders were highest among young, less educated, single parent, female, Black and multi-racial respondents, with some vacillation in such disparities over cohorts. Young, female, and moderately educated respondents also reported higher unmet needs for services. Disparities in estimates of mental health disorders and mental health treatment indicate a striking disequilibrium between the potential need for and the use of mental health services during the COVID-19 pandemic. Rising mental health challenges are being borne largely by young, less advantaged people of color and women, with the potential for expanded interruptions to optimal functioning and societal recovery from COVID-19.
The myriad stressors imposed by the COVID-19 pandemic have impaired mental health and wellbeing. Although evidence from early in the pandemic revealed elevated rates of mental health conditions, research has not documented whether psychological disorders have continued to rise as the pandemic has persisted. In this research, we assess data from over 1.3 million US adults who participated in cross-sectional surveys between April and November, 2020 to track trends in mental health disorder symptoms and services. Our results show that reports of anxiety and depression rose significantly from April to November, 2020 to rates more than four-times higher than in 2019. We also found evidence of growing unmet need for mental health services. Rising mental health challenges are being borne largely by young, less advantaged people of color and women. Growing disparities in mental health disorders and treatment raise concerns for psychological, social, and economic recovery from COVID-19.

PURPOSE: We examined associations between the 2010 Affordable Care Act (ACA) provisions, 2011 Advisory Committee on Immunization Practices (ACIP) recommendation, and 2014 ACA-related health insurance reforms with HPV vaccine initiation rates by sex and health insurance type. METHODS: Using 2009-2015 public and private health insurance claims for 551,764 males and females aged 9-26 years (referred to as youth) from Maine, New Hampshire, and Massachusetts, we conducted linear regression models to examine the associations between three policy changes and HPV vaccine initiation rates by sex and health insurance type. RESULTS: In 2009, HPV vaccine initiation rates for males and females were 0.003 and 0.604 per 100 enrollees, respectively. Among males, the 2010 ACA provisions and ACIP recommendation were associated with significant increases in HPV vaccine uptake among those with private plans (0.207 [0.137, 0.278] and 0.419 [0.353, 0.486], respectively) and Medicaid (0.157 [0.083, 0.230] and 0.322 [0.257, 0.386], respectively). Among females, the 2010 ACA provisions were associated with significant increases in HPV vaccine uptake among Medicaid enrollees only (0.123 [0.033, 0.214]). The ACA-related health insurance reforms were associated with significant increases in HPV vaccine uptake for male and female Medicaid enrollees (0.257 [0.137, 0.377] and 0.214 [0.102, 0.327], respectively), but no differences among privately insured youth. By 2015, there were no differences in HPV vaccine initiation rates between males (0.278) and females (0.305). CONCLUSIONS: Both ACA provisions and the ACIP recommendation were associated with significant increases in HPV vaccine initiation rates among privately and publicly insured males in three New England states, closing the gender gap. In contrast, females and youth with private insurance did not exhibit the same changes in HPV vaccine uptake over the study period.

The purpose of this study was to track trends in mental health symptoms, use of services, and unmet need for services among U.S. adults and to delineate variation across demographic strata. Data were drawn from the 2020 U.S. Household Pulse Survey from repeated cross-sectional online surveys collected between April 23 and November 23, 2020 from 1,483,378 US adults, weighted to represent the U.S. population. Survey respondents self-reported their symptoms of anxiety and depression, use of medication, counseling services, and unmet need for services. Reports of probable anxiety and depression rose significantly through the study period, to prevalence rates of 50% and 44%, respectively, by November 2020, rates six times higher than early 2019 U.S. norms. Use of prescription medication, counseling services, and unmet need for mental health services also rose significantly. Prevalence rates of probable mental health disorders were highest among young, less educated, single, female, Black and Hispanic respondents, with age and education disparities growing over cohorts.

BACKGROUND: Although all 11- or 12-year-olds in the US were recommended to receive a 3-dose series of the human papillomavirus (HPV) vaccine within a 12-month period prior to 2016, rates of completion of the HPV vaccine series remained suboptimal. The effects of the Affordable Care Act (ACA), including private insurance coverage with no cost-sharing and health insurance expansions, on HPV vaccine completion are largely unknown. The aim of this study was to examine the associations between the ACA's 2010 provisions and 2014 insurance expansions with HPV vaccine completion by sex and health insurance type. METHODS: Using 2009-2015 public and private health insurance claims from Maine, New Hampshire, and Massachusetts, we identified 9-to-26-year-olds who had at least one HPV vaccine dose. We conducted a logistic regression model to examine the associations between the ACA policy changes with HPV vaccine completion (defined as receiving a 3-dose series within 12 months from the date of initiation) as well as interactions by sex and health insurance type. RESULTS: Over the study period, among females and males who initiated the HPV vaccine, 27.6 and 28.0%, respectively, completed the series within 12 months. Among females, the 2010 ACA provision was associated with a 4.3 percentage point increases in HPV vaccine completion for the privately-insured (0.043; 95% CI: 0.036-0.061) and a 5.7 percentage point increase for Medicaid enrollees (0.057; 95% CI: 0.032-0.081). The 2014 health insurance expansions were associated with a 9.4 percentage point increase in vaccine completion for females with private insurance (0.094; 95% CI: 0.082-0.107) and a 8.5 percentage point increase for Medicaid enrollees (0.085; 95% CI: 0.068-0.102). Among males, the 2014 ACA reforms were associated with a 5.1 percentage point increase in HPV vaccine completion for the privately-insured (0.051; 95% CI: 0.039-0.063) and a 3.4 percentage point increase for Medicaid enrollees (0.034; 95% CI: 0.017-0.050). In a sensitivity analysis, findings were similar with HPV vaccine completion within 18 months. CONCLUSIONS: Despite low HPV vaccine completion overall, both sets of ACA provisions were associated with increases in completion among females and males. Our results suggest that expanding Medicaid across the remaining states could increase HPV vaccine completion among publicly-insured youth and prevent HPV-related cancers.

Retroviral insertional mutagenesis (RIM) is both a relevant risk in gene therapy and a powerful tool for identifying genes that enhance the competitiveness of repopulating hematopoietic stem and progenitor cells (HSPCs). However, focusing only on the gene closest to the retroviral vector insertion site (RVIS) may underestimate the effects of RIM, as dysregulation of distal and/or multiple genes by a single insertion event was reported in several studies. As a proof of concept, we examined the common insertion site (CIS) Bcl-xL, which revealed seven genes located within ±150 kb from the RVIS for our study. We confirmed that Bcl-xL enhanced the competitiveness of HSPCs, whereas the Bcl-xL neighbor Id1 hindered HSPC long-term repopulation. This negative influence of Id1 could be counteracted by co-expressing Bcl-xL. Interestingly, >90% of early reconstituted myeloid cells were found to originate from transduced HSPCs upon simultaneous overexpression of Bcl-xL and Id1, which implies that Bcl-xL and Id1 can collaborate to rapidly replenish the myeloid compartment under stress conditions. To directly compare the competitiveness of HSPCs conveyed by multiple transgenes, we developed a multiple competitor competitive repopulation (MCCR) assay to simultaneously screen effects on HSPC repopulating capacity in a single mouse. The MCCR assay revealed that multiple genes within a CIS can have positive or negative impact on hematopoiesis. Furthermore, these data highlight the importance of studying multiple genes located within the proximity of an insertion site to understand complex biological effects, especially as the number of gene therapy patients increases.

PURPOSE: Given the rapid expansion of recreational marijuana legalization (RML) polices, it is essential to assess whether such policies are associated with shifts in the use of marijuana and other substances, particularly for adolescents, who are uniquely susceptible to negative repercussions of marijuana use. This analysis seeks to provide greater generalizability, specificity, and methodological rigor than limited prior evidence. METHODS: Youth Risk Behavior Survey data from 47 states from 1999 to 2017 assessed marijuana, alcohol, cigarette, and e-cigarette use among adolescents (14-18+ years; N = 1,077,938). Associations between RML and adolescent past-month substance use were analyzed using quasi-experimental difference-in-differences zero-inflated negative binomial models. RESULTS: Controlling for other state substance policies, year and state fixed effects, and adolescent demographic characteristics, models found that RML was not associated with a significant shift in the likelihood of marijuana use but predicted a small significant decline in the level of marijuana use among users (incidence rate ratio = .844, 95% confidence interval [.720-.989]) and a small increase in the likelihood of any e-cigarette use (odds ratio of zero use = .647, 95% confidence interval [.515-.812]). Patterns did not vary over adolescent age or sex, with minimal differences across racial/ethnic groups. CONCLUSIONS: Results suggest minimal short-term effects of RML on adolescent substance use, with small declines in marijuana use and increase in the likelihood of any e-cigarette use. Given the delayed rollout of commercial marijuana sales in RML states and rapid expansion of RML policies, ongoing assessment of the consequences for adolescent substance use and related health and behavioral repercussions is essential.
