Race, Coping Style, and Substance Use Disorder Among Non-Hispanic African American and White Young Adults in South Florida

C-reactive protein moderates associations between racial discrimination and ventromedial prefrontal cortex activation during attention to threat in Black American women

Prior research has shown that racial discrimination (RD) impacts activation in threat network regions, including the ventromedial prefrontal cortex (vmPFC) and middle occipital cortex during attention to threat-relevant stimuli. However, little is known about the biological mechanisms that may modulate these effects; inflammation may be a pathway linking RD and threat network activation. As such, the current study aimed to explore whether systemic inflammation, measured by C-reactive protein (CRP) levels, may moderate the relationship between RD and activation in the vmPFC and middle occipital cortex during attention to threat. Blood samples for inflammatory marker (CRP) assays were obtained from forty Black American women (mean [SD] age, 39.93 [9.97] years; range, 22-58 years) recruited from an ongoing trauma study; participants also viewed threat-relevant stimuli as part of an attention task during fMRI. We found that CRP moderated the relationship between RD and vmPFC activation during attention to threat, such that participants with relatively higher concentrations of CRP ( ≥ 23.97 mg/L) demonstrated significant positive associations between RD and vmPFC activation [β = 0.18, CI (0.04, 0.32), t = 2.65, p = 0.01]. No significant associations were observed for participants who showed moderate (10.89 mg/L) or low (0.20 mg/L) CRP concentrations. CRP did not moderate the relationship between RD and middle occipital cortex activation. Our data present a mechanism through which RD may influence immune system activation and, in turn, threat network activation. Inflammation may contribute to brain health vulnerabilities in Black Americans via its effects on threat circuits; this merits further investigation in large-scale studies.

The role of substance use disorders in the transition from suicide attempt to suicide death: a record linkage study of a Swedish cohort

BACKGROUND

Suicidal behavior and substance use disorders (SUDs) are important public health concerns. Prior suicide attempts and SUDs are two of the most consistent predictors of suicide death, and clarifying the role of SUDs in the transition from suicide attempt to suicide death could inform prevention efforts.

METHODS

We used national Swedish registry data to identify individuals born 1960-1985, with an index suicide attempt in 1997-2017 (N = 74 873; 46.7% female). We assessed risk of suicide death as a function of registration for a range of individual SUDs. We further examined whether the impact of SUDs varied as a function of (i) aggregate genetic liability to suicidal behavior, or (ii) age at index suicide attempt.

RESULTS

In univariate models, risk of suicide death was higher among individuals with any SUD registration [hazard ratios (HRs) = 2.68-3.86]. In multivariate models, effects of specific SUDs were attenuated, but remained elevated for AUD (HR = 1.86 95% confidence intervals 1.68-2.05), opiates [HR = 1.58 (1.37-1.82)], sedatives [HR = 1.93 (1.70-2.18)], and multiple substances [HR = 2.09 (1.86-2.35)]. In secondary analyses, the effects of most, but not all, SUD were exacerbated by higher levels of genetic liability to suicide death, and among individuals who were younger at their index suicide attempt.

CONCLUSIONS

In the presence of a strong predictor of suicide death - a prior attempt - substantial predictive power is still attributable to SUDs. Individuals with SUDs may warrant additional suicide screening and prevention efforts, particularly in the context of a family history of suicidal behavior or early onset of suicide attempt.

Coping strategies as mediating mechanisms between adolescent polysubstance use classes and adult alcohol and substance use disorders

Adolescent polysubstance use is a robust predictor of substance use in adulthood and can be exacerbated by poor coping with stress over time. We examined whether latent classes of adolescents' polysubstance use predicted alcohol use disorder and substance use disorder diagnoses in adulthood via multiple stress coping strategies. Self-reported frequency of past 3-month alcohol, tobacco, and marijuana use in 792 adolescents (aged 16/17) were used to form latent classes of polysubstance use. Self-reported aggressive, reactive, substance use and cognitive coping strategies (ages 18/19, 22/23, 23/24) were examined as multiple mediators of polysubstance use classes and alcohol use disorder and substance use disorder in adulthood (age 26/27) controlling for demographic covariates. Latent class analysis resulted in High, Experimental, and Low polysubstance use classes. Those in high and experimental polysubstance use classes, compared to those in the low polysubstance use class, had greater use of aggressive and reactive coping strategies, which respectively predicted greater substance use disorder and alcohol use disorder in adulthood. Across all comparisons (high vs low, experimental vs low, and high vs experimental), higher polysubstance use was associated with greater substance use coping, which predicted both alcohol and substance use disorder. Greater polysubstance use, even experimental use, in adolescence is a significant risk factor for developing alcohol use disorder and substance use disorder in adulthood and this occurs, in part, via maladaptive stress coping strategies.

Racial Disparities in Avoidant Coping and Hypertension Among Midlife Adults

While associations between stress and hypertension have been documented, little research has examined the association between coping and hypertension, especially in the context of understanding racial disparities. Utilizing data from the CHDS-DISPAR study, we examine the association between avoidant coping and hypertension among adults age 50 while assessing for potential differences across (1) coping in response to the general stress and discrimination and (2) African American and White racial groups. Coping was measured using a 9-item scale with an avoidant coping subscale (e.g., drinking alcohol). Mean avoidance coping scores were calculated for both general stress and discrimination. No racial differences in avoidant coping were found. Within our sample (n = 414), there was a high burden of hypertension among African American respondents compared to White respondents (50.3% vs. 22.6%). Models assessed associations between avoidant coping and hypertension adjusted for sociodemographic factors, obesity, and either experience of stress or discrimination depending on the coping domain examined. Avoidant coping in response to the general stress and discrimination was associated with increased hypertension among White respondents (PR: 1.63 [95%CI 1.01, 2.24]; PR: 1.69 [95%CI 1.12, 2.26], respectively) and no associations among African American respondents (PR: 0.83 [95%CI 0.57, 1.09]; PR: 0.82 [95%CI 0.52, 1.12], respectively). This research suggests that racial disparities in hypertension may not be attributable to individual-level coping behaviors.

Impairment, Disability, and Substance Use Disorder

According to the social model of disability, it is not individuals' impairments, but societal barriers that cause these impairments to be disabling. Impairment refers to the "loss or abnormality of psychological, physiological, or anatomical structure or function," whereas disability is socially constructed and refers to the inability to independently complete one or more everyday tasks at a "normal" level of functioning. Existing research finds that disability serves as a chronic stressor, and those with disabilities report higher rates of substance use than their able-bodied counterparts. Therefore, this research will be among the first to combine the social model of disability with the stress process framework. It will examine the relationship between impairment and substance use and how disability, as a measure of chronic stress, may affect this relationship. More specifically, using data from the 2019 National Survey on Drug Use and Health (N = 42,739), this article examines the following two research questions: (1) What is the relationship between impairment and substance use disorder? and (2) Does disability, as a measure of chronic stress, mediate the relationship between impairment and substance use disorder? Findings reveal that those with an impairment have significantly greater odds of having a substance use disorder. However, the relationship between impairment and substance use disorder is fully mediated by disability. These findings indicate that disability or the chronic stress one faces living in an inaccessible society, not one's impairments, are what accounts for the increased likelihood of substance use disorder among individuals with disabilities.

Association between maternal psychological factors and offspring executive function: analysis of African-American mother-child dyads

BACKGROUND

Executive function (EF) develops throughout childhood and adolescence; however, little is known about whether and how early life factors are associated with EF during these two stages. This secondary analysis examined the associations between maternal psychological characteristics at 2 years after childbirth and offspring EF at 6 and 18 years.

METHODS

Data were from the 18-year New Mothers' Study in Memphis, TN. Women who self-identified as African-American were included (mother-child dyads: N = 414). Maternal psychological characteristics (e.g., depressive symptoms, self-esteem) were assessed using standardized questionnaires; offspring EF at 6 (i.e., working memory, response inhibition) and 18 years (e.g., working memory, sustained attention) were assessed using age-appropriate cognitive tasks. Statistical analyses included principal component analysis (PCA) and regression models.

RESULTS

PCA reduced the correlated psychological characteristics to two factors: emotionality (depressive symptoms, emotional instability) and psychological resources (self-esteem, mastery, active coping). After controlling for maternal IQ, maternal emotionality was associated with worse working memory and response inhibition (marginally significant) at 6 years. Maternal psychological resources were marginally associated with better working memory at 6 years.

CONCLUSIONS

Maternal psychological characteristics may be associated with later EF in offspring. Future studies are needed to replicate these findings and to explore potential mediators.

IMPACT

African-American mothers' depressive symptoms and emotional instability at 2 years after childbirth were associated with offspring executive function at 6 and 18 years. African-American mothers' psychological resources at 2 years after childbirth were marginally associated with offspring working memory at 6 years. Maternal IQ attenuated all of the associations observed between maternal psychological status and offspring executive function.

COVID-19 Pandemic and Stress: Coping with the New Normal

COVID-19 is the new face of pandemic. Since the discovery of COVID-19 in December 2019 in Wuhan, China, it has spread all over the world and the numbers are increasing day by day. Anyone can be susceptible to this infection but children, older adults, pregnant women, and people with comorbidity are more vulnerable. The spread of coronavirus resulted in closures of schools, businesses, and public spaces worldwide and forced many communities to enact stay at home orders, causing stress to all irrespective of their age, gender, or socioeconomic status. The sudden and unexpected changes caused by the outbreak of coronavirus are overwhelming for both adults and children, causing stress and evoking negative emotions like fear, anxiety, and depression, among different populations. The aim of the paper is to ascertain how stress during this pandemic inculcates various psychological health issues like depression anxiety, OCD, panic behavior, and so on. Further, the paper is an attempt to identify different general as well as population specific coping strategies to reduce the stress level among individuals and prevent various stress-induced psychological disorders with reference to different theories and research articles.

Puff, puff, drink: The association between blunt and alcohol use among African American adolescents and young adults

Although African Americans report lower levels of alcohol use relative to their White counterparts, they experience higher rates of alcohol-related problems (e.g., alcohol dependence). One understudied connection between alcohol use and dependence is the dual use of illicit drugs, especially marijuana use. It is speculated that blunt use in combination with alcohol will have more adverse alcohol-related consequences among African Americans than alcohol use alone or alcohol and nonblunt marijuana use. The current study uses pooled data from the 2011-2014 National Survey on Drug Use and Health to examine the odds of alcohol dependence based on alcohol and marijuana typology in comparison to alcohol only users. Among 11,124 African American adolescents (12-17) and young adults (18-25) who consumed alcohol in the past year, 57.5%, 36.8%, and 5.7% reported alcohol use alone and in combination with blunt use and nonblunt marijuana use, respectively. Relative to alcohol users only, youth who used alcohol and blunts had increased odds of having alcohol dependence. This association was not found among youth who reported alcohol and nonblunt marijuana use. The increased rates of alcohol dependence highlight the public health concern of dual alcohol and a specific type of marijuana use (i.e., blunts) among African American youth.
