Introduction: Black people are disproportionately burdened by tobacco-related diseases and are less successful at cigarette cessation with current treatments. We know little about the effectiveness of e-cigarettes as a smoking cessation method compared to currently approved methods in Black adults who smoke. Many Black adults report experiencing racial discrimination in health care, but if discrimination is related to utilization of smoking cessation aids including e-cigarettes and success with smoking cessation in this population is unclear.

Article Synopsis
  • - The study analyzed 685 Black adults aged around 57 to see how loneliness and income affect accelerated aging using a new DNA-methylation index called DunedinPACE.
  • - Findings showed that as people aged, their rate of physiological aging increased, and changes in loneliness and income significantly impacted this aging over an 11-year period.
  • - Importantly, while smoking behavior was also linked to aging, loneliness and income still had strong effects even after controlling for other factors like smoking and alcohol use.

Article Synopsis
  • Excessive alcohol consumption (EAC) is linked to serious health outcomes and epigenetic aging (EA), but self-reported measures of EAC often show inconsistent results, highlighting the need for better assessment tools.
  • New DNA methylation indices like the Alcohol T Score (ATS) and Methyl DetectR (MDR), along with the carbohydrate deficient transferrin (CDT), were tested to evaluate their effectiveness in measuring EAC's impact on EA in a study with 437 young Black American adults.
  • Findings revealed that non-self-report indices (ATS, MDR, and CDT) had significant correlations with EA and immune cell counts, while self-reports showed weak connections; notably, the ATS demonstrated a strong predictive capacity

Introduction: Black communities are targeted by more cigarette advertisements than White communities and racial discrimination among Black people is related to cigarette use. However, little is known about these factors with non-cigarette tobacco product use among Black adults. Therefore, this study assessed the association of non-cigarette advertisement exposure and racial discrimination with use of non-cigarette tobacco products among Black adults.

Objective: The objective of this study was to investigate racial centrality as a mediator of the association between Black adolescents' racial discrimination experiences and their cigarette use in early adulthood.

Methods: The data were drawn from the Family and Community Health Study, which is a longitudinal study of Black American families that began in 1996. Families with a child in 5th grade who identified as Black or African American were recruited from Iowa and Georgia.

Smoking and Heavy Alcohol Consumption (HAC) are established risk factors for myriad complex disorders of ageing. Yet many prior studies of Epigenetic Ageing (EA) have shown only modest effects of smoking and drinking on accelerated ageing. One potential reason for this conundrum might be the reliance of some prior EA studies on self-reported substance use, which may be unreliable in many samples.

We expand upon prior work (Gibbons et al., ) relating childhood stressor effects, particularly harsh childhood environments, to risky behavior and ultimately physical health by adding longer-term outcomes - deoxyribonucleic acid (DNA) methylation-based measures of accelerated aging (DNA-aging). Further, following work on the effects of early exposure to danger (McLaughlin et al.

Evolving patterns of nicotine and cannabis use by adolescents require new tools to understand the changing epidemiology of these substances. Here we describe the use of a novel epigenetic biomarker sensitive to both tobacco and cannabis smoke in a longitudinal sample of high-risk adolescents. We examine risk factors for positivity for this epigenetic biomarker in comparison to positivity for conventional serum biomarkers of nicotine and cannabis use.

Objective: Numerous studies have found evidence of a link between perceived discrimination and unhealthy behavior, especially substance use. Within this body of literature, however, several studies have found unexpected evidence of a positive relation between perceived racial discrimination among African Americans-mostly women-and certain types of healthy behavior, primarily exercise and healthy eating. The current study further examined this positive relation, including an anticipated moderator: optimism.

Mortality assessments are conducted for both civil and commercial purposes. Recent advances in epigenetics have resulted in DNA methylation tools to assess risk and aid in this task. However, widely available array-based algorithms are not readily translatable into clinical tools and do not provide a good foundation for clinical recommendations.

The initiation of adolescent smoking is difficult to detect using carbon monoxide or cotinine assays. Previously, we and others have shown that the methylation of cg05575921 is an accurate predictor of adult smoking status. But the dose and time dependency of the demethylation response to smoking initiation in adolescents is not yet well understood.

Epigenetic aging (EA) indices are frequently used as predictors of mortality and other important health outcomes. However, each of the commonly used array-based indices has significant heritable components which could tag ethnicity and potentially confound comparisons across racial and ethnic groups. To determine if this was possible, we examined the relationship of DNA methylation in cord blood from 203 newborns (112 African American (AA) and 91 White) at the 513 probes from the Levine PhenoAge Epigenetic Aging index to ethnicity.

The prospective relations between perceived racial discrimination (PRD), assessed at 4 different time periods from childhood through adolescence, along with assessments of PRD from the police ("hassling"), and self-reports of arrest and incarceration at a mean age of 24.5 years, were examined in a sample of 889 African Americans from the Family and Community Health Study. Multiple covariates were included in the analyses (e.

Early identification of smoking, essential for the successful implementation of interventions, arrests the escalation of smoking and smoking-associated risk behaviors in adolescents. However, because nascent smoking is typically episodic and infrequent, enzyme-linked immunoassay reagent-based approaches that detect cotinine, a key nicotine metabolite, are not effective in identifying adolescents in the earliest stages of smoking. Epigenetic methods may offer an alternative approach for detecting early-stage smokers.

Article Synopsis
  • Chronic inflammation and a specific gene are important factors in how cancer develops and gets worse. This study looks at how these two factors are connected and what influences them in people's lives.
  • Researchers studied African Americans to see how things like racial discrimination and having supportive friends or religious beliefs affect inflammation and the gene’s behavior.
  • The results showed that more discrimination leads to more inflammation and less gene activity, while religious beliefs and supportive friends do the opposite. This suggests that managing stress and improving social environments could help reduce cancer risk!

Women and children belonging to a racial/ethnic minority bear a disproportionate burden of psychosocial stress that increases their vulnerability to adverse health outcomes. Hair cortisol has been rapidly advanced as a biomarker of the intensity and course of the stress response over time and may provide an opportunity to increase our understanding of the role of psychological stress in health. However, research on the link between hair cortisol levels and subjective measures of maternal and child stress among low-income and minority individuals is limited.

We examined the prospective relations between a cultural risk factor, perceived racial discrimination (PRD), and subsequent negative affect and health behavior (smoking) in a panel of 889 African American children (part of the Family and Community Health Study). Cultural moderators (protective factors) of these relations were also examined. PRD was assessed six times from ages 10.

Affirming one's racial identity may help protect against the harmful effects of racial exclusion on substance use cognitions. This study examined whether racial versus self-affirmation (vs. no affirmation) buffers against the effects of racial exclusion on substance use willingness and substance use word associations in Black young adults.

Objective: The goal of the study was to examine differential mediation of long-term effects of discrimination on health behaviour and health status by internalising (anxiety and depression) and externalising (hostility and anger), and to explore moderation of these effects, specifically, by the presence of support networks and coping tendencies.

Design: The current analyses employed structural equation modelling of five waves of data from Black female participants of the Family and Community Health Study over 11 years (M age 37-48).

Main Outcomes Measures: The main outcome variables were health status and alcohol use (frequency and problematic consumption).

  • This study looked at how impulsive teenagers react to movie scenes that show drinking in good or bad ways.
  • Teens who were more impulsive were more likely to think positively about drinking when they watched scenes showing fun and social situations.
  • The study found that impulsive teens were quicker to respond to alcohol-related words, which meant they were more willing to drink after seeing the positive clips.

Smoking is the largest preventable cause of morbidity and mortality in the world. Although there are effective pharmacologic and behavioral treatments for smoking cessation, our inability to objectively quantify smokers' progress in decreasing smoking has been a barrier to both clinical and research efforts. In prior work, we and others have shown that DNA methylation at cg05575921, a CpG residue in the aryl hydrocarbon receptor repressor (AHRR), can be used to determine smoking status and infer cigarette consumption history.
