Everyday discrimination indirectly influences smoking cessation through post-quit self-efficacy

Pain Severity in Relation to Smoking Cessation Problems and Self-Efficacy for Quitting among Latinx Individuals Who Smoke Cigarettes: The Moderating Role of Perceived Discrimination

Background: Latinx individuals experience significant tobacco cigarette smoking-related diseases and illnesses. Although most Latinx smokers report a desire to quit smoking, evidenced-based cessation treatments are underutilized in this group, which may partially be due to lower likelihood of receiving advice from a healthcare professional. Further, there are a lack of cessation treatments that account for comorbid symptoms/conditions (e.g., co-occurring pain) and social determinants of health (e.g., perceived discrimination). Extant work has established the reciprocal relation between pain and smoking trajectories. Additionally, although social determinants, such as perceived racial/ethnic discrimination, have demonstrated clinical relevance to a variety of health-related behaviors, limited work has examined the role of perceived discrimination in pain-smoking relations. The current study examined the effects of perceived discrimination and pain severity in relation to smoking cessation problems and self-efficacy for quitting among Latinx cigarette smokers. Method: Participants included 226 (Mage = 34.95 years, SD = 8.62; 38.5% female) adult Latinx daily cigarette smokers. Results: Results indicated that the interaction of pain and perceived discrimination was predictive of greater quit problems (p = 0.041) as well as greater confidence in the ability to refrain from smoking in response to internal (p < 0.001) and external stimuli (p < 0.001). Conclusions: Overall, this work provides a more nuanced understanding of the psychosocial contexts in which Latinx smokers may encounter problems related to quitting, and this data is important for future smoking cessation research and treatment.

Perceived racial/ethnic discrimination and cigarette smoking behaviors among a sample of people with HIV

This study was a secondary analysis of baseline data from a clinical trial of an intensive group-based smoking cessation treatment for people with HIV (PWH) who smoke. It examined the cross-sectional relationship between perceived ethnic discrimination (PED) and cigarette smoking variables (i.e., nicotine dependence, motivation to quit smoking, self-efficacy to quit smoking) among PWH and explored whether depressive symptoms mediated the relationship between PED and smoking variables. Participants (N = 442; Mage = 50.6; 52.8% Male; 56.3% Black, non-Hispanic; 6.3% White, non-Hispanic; 13.3% Hispanic; 87.7% unemployed; 81.6% single) completed measures of demographics, cigarette smoking, depressive symptoms, and PED. Greater PED was related to lower self-efficacy to quit smoking, greater perceived stress, and greater depressive symptoms. In addition, depressive symptoms mediated the relationship between PED and two cigarette smoking variables (i.e., nicotine dependence, self-efficacy to quit smoking). Findings highlight the need for smoking interventions to target PED, self-efficacy, and depressive symptoms to improve smoking cessation variables among PWH.

Does the Chronic Stress of Everyday Discrimination or Race Itself Better Predict AD Onset Risk?

Using evidence from the Health and Retirement Study, we explore racial disparities in Alzheimer's Disease (AD) onset risk. From a stress process perspective, there is substantial evidence in the literature that everyday discrimination is a chronic strain for Black individuals that acts as a social determinant of illness. However, few studies have examined specific relationships between this social stressor, race, and AD onset risk. Using Cox Proportional Hazard Models, we examined racial differences in exposure and vulnerability to everyday discrimination. Findings suggest that everyday discrimination predicts AD onset risk, and Black individuals experience more frequent exposure to everyday discrimination as a chronic strain. However, contrary to the stress process model, Black respondents were not more vulnerable to the effect of everyday discrimination on AD onset risk. Racial bias from medical professionals during the diagnostic process and mortality selection bias may explain this effect. Overall, the results of this study provide further evidence that discrimination is a key factor in predicting AD while also considering that many racial minorities with high rates of this type of social stress may not receive an unbiased diagnosis and/or survive to late life to develop AD.

Perceived discrimination and smoking lapse among Mexican Americans: An ecological momentary assessment study

OBJECTIVE

Racial/ethnic minorities face unique stressors, including perceived discrimination (PD), that may increase the difficulty of quitting smoking relative to the general population of smokers. The current study examines the impact of acute PD on smoking lapse during a quit attempt, as well as potential mechanisms linking PD to lapse among Spanish-speaking Mexican Americans.

METHOD

Participants (N = 169) were Spanish-speaking Mexican Americans living in the United States who completed ecological momentary assessments (EMAs) multiple times per day for 21 days postquit. A multilevel structural equation model decomposed the effect of PD on smoking lapse into indirect effects through negative affect, positive affect, smoking urge, motivation to quit, and self-efficacy.

RESULTS

Results indicated that PD operated indirectly through negative affect, positive affect, and urge to smoke, above and beyond other mechanisms, to increase risk for smoking lapse.

CONCLUSIONS

Findings have direct implications for intervention development among this population, including the potential for developing strategies to buffer the impact of PD, as well as skills to directly manage increased negative affect and urge to smoke. Just-in-time adaptive interventions (JITAIs) might be particularly useful, given they are designed to deliver treatment in real-time (e.g., delivery of strategies to build resilience and implement coping strategies) that could counter the impact of PD on smoking lapse.

Associations between Perceived Racial Discrimination and Tobacco Cessation among Diverse Treatment Seekers

Objectives

This study investigated a) racial/ethnic differences in past-year discrimination experiences and b) associations between discrimination and smoking abstinence.

Design

Prospective, longitudinal analysis of smoking status. Perceived past-year discrimination was assessed at baseline. ANCOVAs and intent-to-treat hierarchical logistic regressions were conducted.

Setting

Dual-site (Tampa, FL and Miami, FL) randomized controlled trial testing the effects of a group cessation intervention plus pharmacotherapy.

Participants

Treatment-seeking adult smokers (N=347; non-Hispanic White, non-Hispanic African American/Black, or Hispanic).

Main Outcome Measures

Biochemically verified 7-day point prevalence abstinence (7-day ppa) was assessed immediately post-intervention and at 6-month follow-up.

Results

After controlling for covariates, African Americans/Blacks reported greater perceived discrimination compared with non-Hispanic Whites (P=.02), and Hispanics (P=.06). Non-Hispanic Whites and Hispanics did not differ in perceived racial/ethnic discrimination experiences over the past year. Irrespective of race/ethnicity, past-year perceived discrimination was inversely associated with 7-day ppa, both post-intervention (AOR=.97, CI: .95-.99) and at 6-months (AOR=.98, CI: .96-.99). Among African Americans/Blacks, past-year perceived discrimination was inversely associated with 7-day ppa, both post-intervention (AOR=.95, CI: .92-.97) and at 6-months (AOR=.97, CI: .94-.99). Perceived discrimination was unrelated to 7-day ppa among Hispanics. Among non-Hispanic Whites, past-year perceived discrimination was inversely associated with post-intervention 7-day ppa (AOR=.95, CI: .91-.99), but not 6-months.

Conclusions

Perceived racial/ethnic discrimination was greater among African American/Black smokers compared with non-Hispanic Whites. Perceived discrimination was negatively associated with tobacco cessation in the full sample, and for African Americans at 6-months post-intervention. These data have implications for intervention delivery and health disparities.

Darker skin color is associated with a lower likelihood of smoking cessation among males but not females

Darker skin color is associated with discrimination and unfair treatment and may contribute to persisting health disparities. This study examined whether darker skin color was associated with smoking cessation and whether this association was moderated by sex and race. This study also explored whether biological and psychosocial factors, including nicotine and cotinine concentrations, discrimination, distrust, and neuroticism, mediated this association. The data for this study came from a prospective smoking cessation intervention that included 224 Black and 225 White adults from Kansas City, Missouri. Skin color was assessed using a DermaSpectrometer to measure melanin contained within the skin. Point prevalence smoking abstinence was biochemically-verified and assessed at weeks 4 and 26. Hierarchical logistic regression analyses were conducted to evaluate hypothesized relations between skin color and smoking cessation. Interactions between race and sex with skin color were also evaluated. While skin color was not associated with smoking cessation in the overall sample or among Blacks only, results indicated that sex moderated the effect of skin color on smoking cessation after adjusting for race and other covariates. Among males, darker skin color was associated with lower odds of achieving smoking abstinence at weeks 4 (OR = 0.60 [95% CI = 0.36, 0.99]) and 26 (OR = 0.52 [95% CI = 0.29, 0.91]). Skin color did not predict smoking cessation among females. Skin color was positively correlated with discrimination (r = 0.15, p = 0.02), cynicism/distrust (r = 0.14, p = 0.03) and neuroticism (r = 0.24, p < 0.01) among males only. However, these factors did not mediate the association between skin color and smoking cessation. Skin color may contribute to cessation-related health disparities among Black males, but more research is needed to understand the psychosocial and biological mechanisms through which skin color influences tobacco cessation.
