Analysis of combined probability and nonprobability samples: A simulation evaluation and application to a teen smoking behavior survey.

In scientific studies with low-prevalence outcomes, probability sampling may be supplemented by nonprobability sampling to boost the sample size of desired subpopulation while remaining representative to the entire study population. To utilize both probability and nonprobability samples appropriately, several methods have been proposed in the literature to generate pseudo-weights, including ad-hoc weights, inclusion probability adjusted weights, and propensity score adjusted weights. We empirically compare various weighting strategies via an extensive simulation study, where probability and nonprobability samples are combined.

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.

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

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.

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.

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.

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

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.

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.

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.

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.

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).

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).

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.

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