Risk perceptions, an important determinant of positive behavioral change, are often conceptualized as additive or multiplicative index two concepts: susceptibility to and severity a health risk. Susceptibility is the possibility experiencing risk, whereas its seriousness harmfulness. This article challenged current theorization risk perceptions. To demonstrate differential perceptions severity, self-report studies (N = 70, each) one reaction time study 476) provided data on 50 conditions...
<h3>Background:</h3> Patient access to their medical records through patient portals (PPs) facilitates information exchange and provision of quality health care. Understanding factors that characterize patients with limited use PPs is needed. <h3>Methods:</h3> Data were from the 2017–2018 Health Information National Trends Survey 5, Cycles 1 2, a nationally representative survey US adults ≥ 18 years old (n = 6789). Weighted multivariate logistic regressions modeled associations between...
Abstract Purpose Although telehealth access and utilization have increased during the pandemic, rural low‐income disparities persist. We sought to assess whether or willingness use differed between non‐rural non‐low‐income adults measure prevalence of perceived barriers. Methods conducted a cross‐sectional study using COVID‐19's Unequal Racial Burden (CURB) online survey (December 17, 2020‐February 2021), which included 2 nationally representative cohorts Black/African American, Latino,...
Objective Under US law, tobacco product marketing may claim lower exposure to chemicals, or risk of health harms, only if these claims do not mislead the public. We sought examine impact such about potential modified products (MRTPs). Methods Participants were national samples 4797 adults and 969 adolescent smokers non-smokers. provided information a MRTP (heated product, electronic cigarette snus). Experiment 1 stated that was as harmful cigarettes less (lower claim). 2 exposed users...
Background Smart lighters track cigarette smoking episodes, which can help identify patterns and intervention approaches to promote cessation. We gauged the acceptability of smart among individuals with low socioeconomic status (SES), a target population for newly developed cessation mobile intervention, evaluate their potential use during pre-quit period. Methods Twelve virtual focus group discussions were conducted 38 current smokers, 18–29 years old, who not 4-year college-educated nor...
Introduction Accumulating evidence suggests that preconception epigenetic changes elevate the risk for obesity throughout lifespan. Little is known about how parents may react to learning parent-child transmission of risk. Further, it unclear trust in science moderate these responses. Methods We compared perceptions, behavioral intentions, perceived control, and information-focused ratings 322 with higher weight status who were randomized read an article role epigenetics intergenerational...
Examine racial/ethnic differences in smoking susceptibility among US youth nonsmokers over time and age.We used nationally representative samples of youths who never tried cigarettes (N = 143 917; age, 9-21, mean, 14.01 years) from National Youth Tobacco Survey, 1999 to 2014. We time-varying effect modeling examine nonlinear trends adjusted for demographics, living with smokers, exposure tobacco advertising.Compared non-Hispanic whites (NHWs), Hispanics were more susceptible 2014 (highest...
Community-based participatory research is an effective tool for improving health outcomes in minority communities. Few community-based studies have evaluated methods of optimizing smartphone apps technology-enabled interventions African Americans.This study aimed to utilize focus groups (FGs) gathering qualitative data inform the development app that promotes physical activity (PA) among American women Washington, DC.We recruited a convenience sample (N=16, age range 51-74 years) from...
Current hypertension guidelines fail to provide a recommendation on when-to-treat, thus disregarding relevant circadian rhythms that regulate blood pressure (BP) level and 24 h patterning medication pharmacokinetics pharmacodynamics. The ideal purpose of ingestion-time (chronopharmacology, i.e. biological rhythm-dependent effects the kinetics dynamics medications, chronotherapy, timing pharmaceutical other treatments optimize efficacy safety) trials should be explore potential impact...

To examine prevalence and correlates of five mutually exclusive tobacco-use patterns among US youth tobacco users.A nationally representative sample users (N = 3202, 9-17 years) was classified into product-use patterns. Weighted multinominal multivariate logistic regression models were used to by gender, race ethnicity, grade level; associations between perceived accessibility products, exposure receptivity pro-tobacco marketing, social benefits smoking, tobacco-associated risks.Dual use...
Background: Few studies have examined differences in product consumption patterns and nicotine tobacco-specific nitrosamines (TSNA) exposure between single versus dual- poly-tobacco users. We applied the Tobacco Product Use Patterns (T-PUPs) model to fill this gap literature.Methods: Data from adults (age ≥18 years) who used any tobacco products during 5 days prior participating 1999-2012 National Health Nutrition Examination Survey (NHANES) were analyzed. Participants classified into seven...
We examined trends in seven mutually exclusive tobacco product use patterns (T-PUPs) nationally representative samples of U.S. youth over time and age. used varying effect modeling on National Youth Tobacco Surveys, 1999–2014 (N = 38662, 9–17 years, M 15.02). Regression coefficients were estimated as a non-parametric function time. T-PUPs cigarette only, non-cigarette combustible noncombustible dual, POLY (i.e. cigarettes, combustibles, noncombustibles) use. Among users, only was the...
Introduction A mixed-method, co-design approach to studying the adoption of mobile health (mHealth) technology among African-American (AA) women has not been fully explored. Qualitative data may contextualise existing knowledge surrounding perceptions mHealth AA as part formative work for designing a physical activity application (app). Methods convenience sample 16 completed an informatics survey prior participating in focus groups exploring their use and apps. Survey responses provided...
Background The use of mobile technologies to deliver behavioral health interventions, including smoking cessation support, has grown. Users’ perceptions are important determinants the adoption and new technologies. However, little is known about users’ as aids, particularly among disadvantaged individuals who smoke. Objective This study aimed examine acceptance for young adults with low socioeconomic status Methods In total, 38 current cigarette smokers, 18 29 years old, wanted quit did not...
Susceptibility to future smoking among youth never smokers has not changed in the past 20 years, although experimental cigarette decreased. We assessed how susceptibility and tobacco industry-related marketing influenced initiation.
Background Ecological models emphasise multilevel influences on health behaviours. While studies show that exposure to price promotions is associated with smoking behaviour and its antecedents, less known about whether these associations differ by macro-level factors such as national promotion policies. Methods Current former smokers ( N =4698) from the International Tobacco Control Policy Evaluation Project four-country cohort were included in weighted multivariate logistic regression...
Behavior change apps have the potential to provide individual support on a population scale at low cost, but they face numerous barriers implementation. Electronic health records (EHRs) in acute care hospitals valuable resource for identifying patients risk, who may benefit from behavior apps. A novel, emerging implementation strategy is use digital technologies not only providing help-seeking individuals also signposting risk services (also called proactive referral United States).
Text-messaging programs for smoking cessation improve abstinence outcomes in the general population. However, little is known about engagement and among African Americans text-messaging programs. The current study compares between Blacks Whites National Cancer Institute's SmokefreeTXT program.Data were from (n = 1333) 7154) who enrolled 6-week program August 2017 June 2018.
