Importance: Smoking prevalence remains alarmingly high among low-income adults, who face disproportionate barriers to cessation and experience unique smoking lapse triggers.

Objective: To compare the efficacy of the Smart-T smartphone intervention, featuring tailored, just-in-time adaptive interventions, with the National Cancer Institute QuitGuide intervention in supporting smoking cessation among adults with low income.

Design, Setting, And Participants: This randomized clinical trial was conducted from August 2019 to November 2023 among US adults with household incomes below 200% of the federal poverty line.

Assessing Daily Antihypertensive Medication Compliance Among Black Adults Using Smartphone-Based Ecological Momentary Assessment: A Feasibility Study.

Lower compliance to antihypertensive medication among the Black population, the gold standard for hypertension management, increases their risk of uncontrolled hypertension and serious health complications. One effective strategy for improving compliance with hypertension self-management involves real-time assessment of behavior using ecological momentary assessment in a person's natural environment. This allows for the determination of self-management behavioral patterns such as medication compliance, as well as overcoming the limitations of recall bias common in retrospective cross-sectional data.

Associations of physical activity, sedentary behavior, and sleep patterns with cognitive function among middle-aged and older adults.

Background: Despite the established evidence that physical activity, sedentary behavior, and sleep affect cognitive function individually, less is known about the combined effects of these movement behaviors. The study aimed to identify movement patterns of physical activity, sitting time, and sleep and to examine the association of movement patterns with cognitive function.

Methods: This cross-sectional study included 1,240 participants aged ≥ 55 years participating in the Cooper Center Longitudinal Study who visited the Cooper Clinic, Dallas (2016-2019) for preventive health care.

Development of an Age-Appropriate Household Dysfunction Measure and its Concurrent Validity With Multiple Outcomes Among Middle School Adolescents in Southeast Texas.

Existing adverse childhood experience (ACE) measures include a limited number of household dysfunction (HD) items and the use of adult-oriented language that is not always appropriate for middle schoolers. We developed an age-appropriate 10-item HD measure informed by previously validated ACE measures and tested its concurrent validity with dating violence (DV) perpetration, lifetime substance use, and mental health outcomes among middle schoolers in Southeast Texas. This cross-sectional study used the baseline data from a DV prevention intervention program for sixth graders ( = 126), Me & You Tech.

Adapting a Mobile Health App for Smoking Cessation in Black Adults With Anxiety Through an Analysis of the Mobile Anxiety Sensitivity Program Proof-of-Concept Trial: Qualitative Study.

Background: At least half of smokers make a serious quit attempt each year, but Black adults who smoke are less likely than White adults who smoke to quit smoking successfully. Black adults who smoke and have high anxiety sensitivity (an individual difference factor implicated in smoking relapse and culturally relevant to Black adults) are even less successful. The Mobile Anxiety Sensitivity Program for Smoking (MASP) is a smoking cessation smartphone app culturally tailored to Black adults who smoke to increase smoking cessation rates by targeting anxiety sensitivity.

Detecting Deception and Ensuring Data Integrity in a Nationwide mHealth Randomized Controlled Trial: Factorial Design Survey Study.

Background: Social behavioral research studies have increasingly shifted to remote recruitment and enrollment procedures. This shifting landscape necessitates evolving best practices to help mitigate the negative impacts of deceptive attempts (eg, fake profiles and bots) at enrolling in behavioral research.

Objective: This study aimed to develop and implement robust deception detection procedures during the enrollment period of a remotely conducted randomized controlled trial.

Associations between cannabis use and same-day health and substance use behaviors.

Objective: Cannabis use has increased in the United States as states have legalized/decriminalized recreational and/or medicinal use. The primary aim of this study was to examine daily associations between cannabis use and health (physical activity [PA]) and substance use (alcohol consumption, cigarette use) behaviors.

Method: Data from a 28-day nationwide study that prompted daily ecological momentary assessments (EMAs) were used to assess daily cannabis use, moderate-to-vigorous PA (MVPA), alcohol containing drinks consumed, and cigarettes smoked.

Impact of prenatal exposure to delta 9-tetrahydrocannabinol and cannabidiol on birth size and postnatal growth trajectories.

Background: Prenatal exposure to cannabis (or more specifically, delta 9-tetrahydrocannabinol [Δ9-THC]) has been consistently linked to low birthweight. Animal models further show that Δ9-THC is associated with rapid postnatal growth. Whether this association is modified by breastfeeding is unknown.

Associations of Muscle-Strengthening Activity and Cognitive Function in Community-Dwelling Middle-Aged and Older Adults.

Objective: To determine the associations between muscle-strengthening activity (MSA) and cognitive function among middle-aged and older adults.

Methods: This cross-sectional study included 2973 participants aged ≥55 in the Cooper Center Longitudinal Study. Participants self-reported leisure-time physical activity.

Functional Concurrent Regression Mixture Models Using Spiked Ewens-Pitman Attraction Priors.

Functional concurrent, or varying-coefficient, regression models are a form of functional data analysis methods in which functional covariates and outcomes are collected concurrently. Two active areas of research for this class of models are identifying influential functional covariates and clustering their relations across observations. In various applications, researchers have applied and developed methods to address these objectives separately.

Problematic social media use and vaping among Mexican-American college students.

Introduction: Social media use and vaping nicotine are highly prevalent in the daily lives of young adults, especially among Mexican-American college students. The excessive and compulsive use of social media platforms, coupled with the urge to stay continuously connected, can lead to problematic social media use. To date, no studies have explored the impact of problematic social media use on the daily patterns of vaping among this vulnerable population.

The Impact of Household Dysfunction on Dating Violence Perpetration Among Adolescents in the United States: A Scoping Review.

Adverse childhood experiences, such as household dysfunction (HD), play a central role in how adolescents establish, experience, and navigate the challenges of relationship formation, maintenance, and dissolution. HD exposures have been independently associated with dating violence (DV) perpetration in both adolescents and adults. However, research examining the association between the concurrent effect of HD on DV perpetration, especially among adolescents remains scarce.

Financial Incentives for Smoking Cessation Among Socioeconomically Disadvantaged Adults: A Randomized Clinical Trial.

Importance: Socioeconomically disadvantaged individuals (ie, those with low socioeconomic status [SES]) have difficulty quitting smoking and may benefit from incentive-based cessation interventions.

Objectives: To evaluate the impact of incentivizing smoking abstinence on smoking cessation among adults with low SES.

Design, Setting, And Participants: This study used a 2-group randomized clinical trial design.

Does the Relationship between Affect and Social Interactions among Adults Experiencing Homelessness Differ during Moments when at a Shelter versus Not?

The prevalence of alcohol use disorders is higher amongst adults experiencing homelessness (AEH) compared with domiciled adults. Greater exposure to heavy drinkers increases personal risk for heavy alcohol use. AEH spend substantial periods of time at shelters and report greater pressure to use alcohol when near shelter locations, as well as greater negative affect when near a shelter.

Mobile Health Interventions for Substance Use Disorders.

Substance use disorders (SUDs) have an enormous negative impact on individuals, families, and society as a whole. Most individuals with SUDs do not receive treatment because of the limited availability of treatment providers, costs, inflexible work schedules, required treatment-related time commitments, and other hurdles. A paradigm shift in the provision of SUD treatments is currently underway.

Associations between morning affect and later-day smoking urges and behavior.

Objective: Affective experiences are associated with smoking urges and behavior. Few studies have examined the temporal nature of these associations within a day, such as whether positive and negative affect in the morning are associated with smoking urges and behavior later in the day.

Method: Participants ( = 63; = 50 years, 48% female; 60% White) were randomized into one of three smoking cessation interventions and answered up to five daily ecological momentary assessments for 28 days during a quit attempt ( = 21.

Nicotine dependence among young adults: Comparing exclusive ENDS users to exclusive cigarette smokers.

Purpose: No studies of young adults have compared symptoms of nicotine dependence among exclusive past 30-day (P30D) ENDS users versus exclusive P30D cigarette smokers.

Methods: Participants at Wave 14 (Fall 2021) of The Texas Adolescent and Tobacco Marketing Surveillance System (TATAMS) (n = 2,341; mean age = 20.95 years old) who reported P30D exclusive ENDS use (n = 212) and P30D exclusive cigarette smoking (n = 46).
