Associations of Impulsivity and Risky Decision-Making with E-Cigarette-Related Outcomes Among Adolescents with Congenital Heart Disease: Variable- and Person-Oriented Approaches.

Adolescents with congenital heart disease (CHD) have elevated risk for acquired cardiovascular complications, increasing their vulnerability to e-cigarette-related health harms. Impulsivity and risky decision-making have been associated with adolescent substance use, but the relationships between these factors and e-cigarette-related outcomes among cardiovascular at-risk adolescents with CHD are unknown. This cross-sectional study aimed to (a) determine the associations of impulsivity and risky decision-making with e-cigarette-related outcomes (i.e. susceptibility, ever use, perceptions of harm and addictiveness) via variable-oriented analysis (logistic regression), (b) identify groups of adolescents with similar profiles of impulsivity and risky decision-making via exploratory person-oriented analysis (latent profile analysis; LPA), and (c) examine differences on e-cigarette-related outcomes between profile groups. Adolescents aged 12 to 18 years with CHD (N = 98) completed a survey assessing impulsivity facets (Short UPPS-P) and e-cigarette-related outcomes and were administered a risky decision-making task (Iowa Gambling Task, Version 2; IGT2). In variable-oriented analyses, impulsivity facets (negative urgency, positive urgency, lack of premeditation) but not risky decision-making were associated with e-cigarette susceptibility and ever use. The exploratory LPA identified two groups with similar patterns of responding on the Short UPPS-P and IGT2 labeled "Low Impulsivity" and "High Impulsivity," which were primarily characterized by significant differences in negative and positive urgency. Adolescents in the High Impulsivity group had increased odds of e-cigarette susceptibility but not ever use compared to the Low Impulsivity group. This work indicates that strategies to prevent e-cigarette use among adolescents with CHD may be enhanced by addressing impulsivity, particularly negative and positive urgency.

Geometric framework for statistical analysis of eye tracking heat maps, with application to a tobacco waterpipe study.

Health warning labels have been found to increase awareness of the harmful effects of tobacco products. An eye tracking study was conducted to determine the optimal placement and type of a health warning label on tobacco waterpipes. Participants viewed images that contained one of (1) four waterpipes, (2) three different types of warning labels, (3) placed in three locations. Typically, statistical analysis of eye tracking data is conducted based on summary statistics such as total dwell time, duration score, and number of visits to an area of interest. However, these summary statistics fail to capture the complete variability in a participant's eye movement. Instead, we propose to estimate heat maps defined on the entire image domain using the raw two-dimensional coordinates of eye movement via kernel density estimation. For statistical analysis of heat maps, we adopt the Fisher-Rao Riemannian geometric framework, which enables computationally efficient comparisons of heat maps, statistical summarization and exploration of variability in a sample of heat maps, and metric-based hierarchical clustering. We apply this framework to eye tracking data from the tobacco waterpipe study and comment on the results in the context of the optimal placement and type of health warning labels on tobacco waterpipes.

The racial disparity of severe maternal morbidity across weeks of gestation: a cross-sectional analysis of the 2019 National Inpatient Sample.

BACKGROUND: Severe maternal morbidity is increasing in the United States. Black women experience the highest rates of severe maternal morbidity and also of preterm births, which are associated with severe maternal morbidity. The racial disparity of severe maternal morbidity across weeks of gestation has not been well-studied. OBJECTIVE: This study aimed to evaluate differences in severe maternal morbidity between Black and White birthing people by week of gestation. Differences may indicate periods of pregnancy when Black women are particularly vulnerable to severe maternal morbidity and may require additional interventions. STUDY DESIGN: This was a cross-sectional study using the National Inpatient Sample from 2019. We used International Classification of Diseases codes from Centers for Disease Control and Prevention guidelines to identify severe maternal morbidity from delivery hospitalizations. We examined the rates of severe maternal morbidity in Black vs White women by week of gestation to evaluate periods of pregnancy when Black women experience additional risks of severe maternal morbidity while adjusting for age, region, medical comorbidities, and Medicaid enrollment. Severe maternal morbidity was analyzed while both including and excluding cases for which blood transfusion was the only indicator of severe maternal morbidity. RESULTS: Overall, Black birthing people had twice the rate of severe maternal morbidity births compared with White birthing people (2.7% vs 1.3%; P<.0001) and were more likely to deliver preterm (14.7% vs 9.4%; P<.0001). The racial disparity of severe maternal morbidity was present throughout all weeks of gestation, with the largest gap observed at extremely and moderately preterm gestations (22-33 weeks). Rates of severe maternal morbidity for Black women peaked at 22 to 33 weeks' gestation and were lowest at term (≥37 weeks). Black women had a greater proportion of severe maternal morbidity cases due to blood transfusion (68.3% vs 64.5%; P<.01) and acute renal failure (11.1% vs 8.5%; P<.001). CONCLUSION: Black women experience a substantially higher rate of severe maternal morbidity at preterm gestations (22-36 weeks) in addition to higher rates of preterm delivery. Even when accounting for age, medical comorbidities, and social determinants, Black birthing people have higher odds of severe maternal morbidity throughout pregnancy.

Untargeted Metabolomics and Body Mass in Adolescents: A Cross-Sectional and Longitudinal Analysis.

Obesity in children and adolescents has increased globally. Increased body mass index (BMI) during adolescence carries significant long-term adverse health outcomes, including chronic diseases such as cardiovascular disease, stroke, diabetes, and cancer. Little is known about the metabolic consequences of changes in BMI in adolescents outside of typical clinical parameters. Here, we used untargeted metabolomics to assess changing BMI in male adolescents. Untargeted metabolomic profiling was performed on urine samples from 360 adolescents using UPLC-QTOF-MS. The study includes a baseline of 235 subjects in a discovery set and 125 subjects in a validation set. Of them, a follow-up of 81 subjects (1 year later) as a replication set was studied. Linear regression analysis models were used to estimate the associations of metabolic features with BMI z-score in the discovery and validation sets, after adjusting for age, race, and total energy intake (kcal) at false-discovery-rate correction (FDR) ≤ 0.1. We identified 221 and 16 significant metabolic features in the discovery and in the validation set, respectively. The metabolites associated with BMI z-score in validation sets are glycylproline, citrulline, 4-vinylsyringol, 3'-sialyllactose, estrone sulfate, carnosine, formiminoglutamic acid, 4-hydroxyproline, hydroxyprolyl-asparagine, 2-hexenoylcarnitine, L-glutamine, inosine, N-(2-Hydroxyphenyl) acetamide glucuronide, and galactosylhydroxylysine. Of those 16 features, 9 significant metabolic features were associated with a positive change in BMI in the replication set 1 year later. Histidine and arginine metabolism were the most affected metabolic pathways. Our findings suggest that obesity and its metabolic outcomes in the urine metabolome of children are linked to altered amino acids, lipid, and carbohydrate metabolism. These identified metabolites may serve as biomarkers and aid in the investigation of obesity's underlying pathological mechanisms. Whether these features are associated with the development of obesity, or a consequence of changing BMI, requires further study.

Effects of "Tobacco Free" Language in Warning Labels on Perceptions of Electronic Cigarettes and Nicotine Pouches among Young Adult Men: A Randomized Trial.

Background: Manufacturers of Puff Bar electronic cigarettes (e-cigarettes) and Fre nicotine pouches claim that their products contain synthetic nicotine. The packages for Puff Bar and Fre have modified versions of the warning labels required by the Food and Drug Administration (FDA) for tobacco products, which specify that Puff Bar and Fre products contain "tobacco free" or "non-tobacco" nicotine, respectively. We evaluated whether exposure to these "tobacco free" warning labels was associated with differing perceptions about the products. Method: N = 239 young adult men who were enrolled in a cohort study completed a short online experiment. Participants were randomly assigned to view either packages of Puff Bar and Fre nicotine pouches with the standard FDA warning or packages with the standard FDA warning + the tobacco free descriptor. We compared harm and addictiveness perceptions and products' perceived substitutability for cigarettes and smokeless tobacco (SLT) by exposure to a "tobacco free" warning. Results: Viewing a Puff Bar package with a "tobacco free" warning label was associated with increased perceived substitutability of the product for cigarettes and smokeless tobacco (p's<.05). Viewing a Fre package with a "non-tobacco" warning label was associated with thinking the product was less harmful than SLT (p<.01). Conclusions: "Tobacco free" descriptors in warning labels for e-cigarettes and nicotine pouches affect young adults' perceptions of the products. To date, it is unclear whether the FDA will continue to permit "tobacco free" descriptors in warning labels. As e-cigarettes and nicotine pouches are increasingly marketed with "tobacco free" language, urgent action is needed.

Examining trends in health care access measures among low-income adult smokers in Ohio: 2012-2019.

Smokers are more likely to be low-income with limited access to health services. Although Medicaid expansion under the Patient Protection and Affordable Care Act improved access to care for low-income adults, long-term trends in health care access among low-income smokers remain uncharacterized. The study evaluated changes in five access measures among low-income nonelderly (19-64) adults (N = 28976) across smoking status using pooled data from a statewide survey in Ohio covering pre- (i.e., 2012) and post-Medicaid expansion periods (2015, 2017, and 2019) guided by a comprehensive framework of health care access. We found improvements in some, but not all, health care access measures among low-income smokers in the post-Medicaid-expansion period compared to the pre-expansion period. Compared to 2012, the odds for unmet dental care needs declined in 2015 (aOR = 0.67, 95 % CI = 0.45-1.01), 2017 (aOR = 0.53, 95 % CI = 0.35-0.81), and 2019 (aOR = 0.65, 95 % CI = 0.40-1.05) (p trend < 0.001). Similarly, the odds for unmet other health care needs (i.e., medical exams and supplies) were lower in 2015 (aOR = 0.64, 95 % CI = 0.39-1.06), 2017 (aOR = 0.56, 95 % CI = 0.34-0.93), and 2019 (aOR = 0.47, 95 % CI = 0.27-0.83) (p trend < 0.001). Difficulty paying medical bills was also significantly lower in 2015 (aOR = 0.62, 95 % CI = 0.43-0.89), 2017 (aOR = 0.57, 95 % CI = 0.39-0.83) and 2019 (aOR = 0.57, 95 % CI = 0.37-0.87) (p trend < 0.001). While there was notable progress in measures of affordability (i.e., paying medical bills) as well as care availability and accommodation (i.e., unmet needs), there were no meaningful changes in the approachability of care (i.e., having a usual source of care).

The Association of Global and Disease-Related Stress With Susceptibility to and Use of E-Cigarettes and Marijuana Among Adolescents With Congenital Heart Disease.

OBJECTIVE: Adolescents with congenital heart disease (CHD) are exposed to disease-related stressors and have elevated risk for cardiovascular and cognitive complications that are exacerbated by e-cigarettes and marijuana. The aims of this cross-sectional study are to: (1) identify the association between perceived global and disease-related stress and susceptibility to e-cigarettes and marijuana, (2) determine if the association between stress and susceptibility differs by gender, and (3) explore the association between stress and ever use of e-cigarettes and marijuana among adolescents with CHD. METHODS: Adolescents with CHD (N = 98; aged 12-18 years) completed self-report measures of susceptibility to/ever use of e-cigarettes and marijuana and global and disease-related stress. RESULTS: Susceptibility to e-cigarettes and marijuana was reported by 31.3% and 40.2% of adolescents, respectively. Ever use of e-cigarettes and marijuana was reported by 15.3% and 14.3% of adolescents, respectively. Global stress was associated with susceptibility to and ever use of e-cigarettes and marijuana. Disease-related stress was associated with susceptibility to marijuana. Females reported more global and disease-related stress than males, but the association of stress with susceptibility to e-cigarettes and marijuana did not differ by gender. CONCLUSIONS: Susceptibility to e-cigarettes and marijuana is common among adolescents with CHD and is associated with stress. Future work to examine the longitudinal associations between susceptibility, stress, and use of e-cigarettes and marijuana is warranted. Global stress may be an important consideration in the development of strategies to prevent these risky health behaviors among adolescents with CHD.

Relation Between Smoking Status and Subjective Cognitive Decline in Middle Age and Older Adults: A Cross-Sectional Analysis of 2019 Behavioral Risk Factor Surveillance System Data.

BACKGROUND: Smoking status may influence subjective cognitive decline (SCD); however, few studies have evaluated this association. OBJECTIVE: To assess whether smoking status is associated with SCD among middle age and older adults, and to determine if this association is modified by sex at birth. METHODS: A cross-sectional analysis was conducted using data from the 2019 Behavioral Risk Factor Surveillance System (BRFSS) survey to analyze the relationship between SCD and smoking status (current, recent former, and remote former). Eligible respondents included participants 45 years of age or older who responded to the SCD and tobacco questions of interest. Survey-weighted Poisson regression models were employed to estimate the crude and adjusted prevalence ratios (cPR/aPR) and corresponding 95% confidence intervals (CI) of the association between smoking status and SCD. A Wald test was computed to determine the significance of the interaction term between smoking status and sex (α= 0.05). RESULTS: There were 136,018 eligible respondents, of which approximately 10% had SCD. There was a graded association between smoking and SCD, with the greatest prevalence of SCD among current smokers (aPR = 1.87; CI: 1.54, 2.28), followed by recent former smokers (aPR = 1.47; 95% CI: 1.02, 2.12), and remote former smokers (aPR = 1.11; 95% CI: 0.93, 1.33) each compared to never smokers. There was no evidence of effect modification by sex (p interaction = 0.73). CONCLUSION: The consistency of smoking as a risk factor for objective and subjective cognitive decline supports the need for future studies to further the evidence on whether changes to smoking status impacts cognition in middle age.

Adherence to COVID-19 Protective Measures in a Longitudinal Sample of Male Youth.

BACKGROUND: Adherence to COVID-19 protective measures is lowest for young people and males. The current study investigated characteristics associated with adherence to COVID-19 protective measures among male youth during the early months of the pandemic. METHOD: The study used data from a prospective cohort study among male youth with baseline assessment in 2015/2016 and follow-up measurements in 2019 and summer 2020. Attrition-weighted multivariable ordinal logistic and log-binomial regression models were used to assess factors associated with adherence to overall and specific adherence measures, respectively. RESULTS: Among 571 male youth (mean age 18.5), overall adherence was higher for those who were older (OR: 1.15; 95% CI: 1.03-1.30), non-White (OR: 1.96; 95% CI: 1.20-3.32), and residing in an urban area (OR: 2.06; 95% CI: 1.46-3.01). Overall adherence was lower for those who had a history of being drunk (OR: 0.65; 95% CI: 0.42-0.99). For outdoor mask-wearing, adherence was higher for youth with attention-deficit disorder or attention-deficit/hyperactivity disorder (RR: 1.58; 95% CI: 1.16-1.97) and lower for youth who currently used tobacco products (RR: 0.42; 95% CI: 0.21-0.70). Before a statewide mask mandate was issued, non-White youth were more likely to report wearing masks in outdoor spaces than their non-Hispanic White peers (RR: 2.34; 95% CI: 1.75-3.23). CONCLUSION: The study identified demographic, psychosocial, and behavioral factors associated with adherence to COVID-19 protective behaviors among male youth. The findings illustrate characteristics that could be leveraged for targeted preventive efforts during the ongoing pandemic and future outbreaks in a low-compliance group.

Case-case-control study of risk factors for carbapenem-resistant Enterobacterales infections among hospitalized patients.

Objective: To identify important risk factors for carbapenem-resistant Enterobacterales (CRE) infections among hospitalized patients. Design: We utilized a case-case-control design that compared patients with CRE infections to patients with carbapenem-susceptible Enterobacterales (CSE) infections and randomly selected controls during the period from January 2011 through December 2016. Setting: The study population was selected from patients at a large metropolitan tertiary-care and instructional medical center. Patients: Cases of CRE were defined as initial admission of adults diagnosed with a bacterial infection of an Enterobacterales species resistant clinically or through sensitivity testing to carbapenems 48 hours or more after admission. Cases of CSE were selected from the same patient population as the CRE cases within a 30-day window for admission, with diagnostic pathogens identified as susceptible to carbapenems. Controls were defined as adult patients admitted to any service within a 30-day window from a CRE case for >48 hours who did not meet either of the above case definitions during that admission. Results: Antibiotic exposure within 90 days prior to admission and length of hospital stay were both associated with increased odds of CRE and CSE infections compared to controls. Patients with CRE infections had >18 times greater odds of prior antibiotic exposure compared to patients with CSE infections. Conclusions: Antibiotic exposure and increased length of hospital stay may result in increased patient risk of developing an infection resistant to carbapenems and other ß-lactams.

Geographic Differences in JUUL Use and Risk Perceptions.

PURPOSE: The aim of this study was to compare prevalence of JUUL use and JUUL risk perceptions between adolescents living in an urban area versus Appalachian areas of the U.S. METHODS: Data were drawn from a prospective cohort study of adolescent males (the Buckeye Teen Health Study, or BTHS); our cross-sectional analysis used data from one timepoint, collected between January and December 2019 (N = 873). Chi-square tests and multivariable logistic regression compared JUUL use prevalence and risk perceptions between participants in an urban Ohio county and nine predominantly rural Appalachian Ohio counties. RESULTS: Over a quarter of the sample (29.2%) had ever used JUUL. In the unadjusted model, prevalence of JUUL use was similar between regions but Appalachian participants perceived JUUL as more harmful (p < .001) and more addictive (p = .04) than urban participants. In the adjusted model, region was not significantly related to current JUUL use (OR: 1.20, 95% CI: 0.77, 1.87) or ever JUUL use (OR: 1.15, 95% CI: 0.83, 1.60). CONCLUSIONS: JUUL use was similar between urban and Appalachian participants despite regional differences in risk perceptions. Interventions that only target risk perceptions may not be sufficient to prevent adolescent e-cigarette use, particularly in rural communities.

Testing if attitudes mediate the association between advertising exposure and adolescent tobacco use.

INTRODUCTION: A growing body of evidence indicates that exposure to tobacco advertising among adolescents increases the likelihood of subsequent tobacco use. It is important to understand the process by which this occurs, in order to appropriately target factors for intervention. The objective of this study was to test whether attitudes towards tobacco advertising mediates the impact of advertising exposure on tobacco use. METHODS: From an ongoing prospective cohort study of male adolescents (aged 11-16 at baseline), we recruited a subset of tobacco users and non-users to participate in an additional ecological momentary assessment (EMA) project (N = 164). Adolescents completed smartphone-based surveys 2-3 times/day over a 10-day period with items assessing their exposures and attitudes towards tobacco-related advertising. If participants reported exposure to tobacco advertising, they were asked about their attitudes toward it (how much they enjoyed it, liked it, and found it appealing). RESULTS: Adolescents who reported a greater amount of advertising exposure during the EMA period were more likely to report past-30-day tobacco use at their next cohort follow-up (6-12 months later). Moreover, the impact of advertising exposure on subsequent use was mediated by attitudes toward the tobacco advertisements, as reported during the EMA. This effect remained after controlling for baseline tobacco use. CONCLUSIONS: By pairing EMA with long-term follow-up, we identified attitudes as a mediator between adolescent advertising exposure and subsequent tobacco use. Interventions to lessen adolescents' positive attitudes toward tobacco advertisements may help disrupt this impact.

Prospective associations between attitudes toward alcohol advertisements and alcohol use behaviors among adolescent boys.

Objectives: Earlier initiation of alcohol use and problematic drinking among adolescents are linked with adverse health outcomes. Exposure to alcohol advertisements is associated with drinking among adolescents, but the association between the attitudes toward alcohol advertisements and drinking behaviors is understudied. We evaluated the association between attitudes towards alcohol advertisements and initiation of alcohol use among adolescent boys. Methods: Adolescent boys from urban and Appalachian Ohio enrolled in a prospective study and reported whether they had ever consumed alcohol or been drunk at baseline (N = 1220; ages 11-16 years) and at the 24-month follow up (N = 891). Attitudes toward alcohol advertisements were measured at baseline following a brief advertisement viewing activity. Adjusted logistic regression models were used to estimate associations between attitudes toward advertisements and initiating alcohol use or drunkenness at the 24-month follow-up. Results: Adolescent boys reporting any positive attitudes toward alcohol advertisements had higher odds of initiating alcohol use (aOR = 2.00, 95% CI [1.16, 3.44]), and attitudes were marginally associated with incident drunkenness (aOR = 2.20, 95% CI [0.94, 5.12]). Increasing age, higher household income, ever use of tobacco, and frequency of visiting alcohol retailers were also associated with greater odds of incident alcohol use and/or drunkenness. Conclusions: Attitudes toward alcohol advertisements at baseline were associated with alcohol drinking behaviors 24-months later among adolescent boys. Results highlight the importance of media literacy interventions targeted to adolescents.

Efficacy of an acceptance and commitment therapy-based smartphone application for helping rural populations quit smoking: Results from the iCanQuit randomized trial.

Limited access to evidence-based smoking cessation interventions among rural populations contributes to high rates of cigarette smoking and poor cessation outcomes. Yet, accessible digital interventions for cessation focusing on rural populations are lacking. In a secondary analysis, we determined the acceptability and efficacy of an Acceptance and Commitment Therapy (ACT)-based smartphone application (iCanQuit) relative to a U.S. Clinical Practice Guidelines (USCPG)-based smartphone application (QuitGuide) for smoking cessation among rural participants enrolled in the two-arm randomized iCanQuit trial. Participants were enrolled between May 2017 and September 2018 and randomized to either receive iCanQuit or QuitGuide for 12-months. Rural residence was determined by sub-county level Rural-Urban Commuting Area codes. A total of 550 rural participants were recruited from 43 U.S. states. Self-reported complete-case 30-day point-prevalence abstinence was 15% (33/226) for iCanQuit vs. 9% (22/253) for QuitGuide at 3-months (OR = 1.83; 95% CI: 1.03, 3.25) and 29% (66/231) for iCanQuit vs. 25% (64/288) for QuitGuide at 12-months (OR = 1.19 95% CI: 0.80, 1.79). Retention rate was 89% at 12-months and did not differ by arm. iCanQuit vs. QuitGuide participants were significantly more engaged and satisfied with the iCanQuit application. Increased acceptance of internal cues to smoke mediated the effect of treatment on cessation. Findings suggest that iCanQuit had significantly higher short-term quit rates, descriptively higher long-term quit rates, and operated through its hypothesized mechanisms of action relative to QuitGuide. Future larger studies are needed to further evaluate the efficacy of and methods for disseminating the iCanQuit application for smoking cessation among U.S. rural adults nationwide.
