RESUMO

Much remains unknown about the etiology of compulsion-like alcohol drinking, where consumption persists despite adverse consequences. The role of the anterior insula (AIC) in emotion, motivation, and interoception makes this brain region a likely candidate to drive challenge-resistant behavior, including compulsive drinking. Indeed, subcortical projections from the AIC promote compulsion-like intake in rats and are recruited in heavy-drinking humans during compulsion for alcohol, highlighting the importance of and need for more information about AIC activity patterns that support aversion-resistant responding. Single-unit activity was recorded in the AIC from 15 male rats during alcohol-only and compulsion-like consumption. We found three sustained firing phenotypes, sustained-increase, sustained-decrease, and drinking-onset cells, as well as several firing patterns synchronized with licking. While many AIC neurons had session-long activity changes, only neurons with firing increases at drinking onset had greater activity under compulsion-like conditions. Further, only cells with persistent firing increases maintained activity during pauses in licking, suggesting roles in maintaining drive for alcohol during breaks. AIC firing was not elevated during saccharin drinking, similar to lack of effect of AIC inhibition on sweet fluid intake in many studies. In addition, we observed subsecond changes in AIC neural activity tightly entrained to licking. One lick-synched firing pattern (determined for all licks in a session) predicted compulsion-like drinking, while a separate lick-associated pattern correlated with greater consumption across alcohol intake conditions. Collectively, these data provide a more integrated model for the role of AIC firing in compulsion-like drinking, with important relevance for how the AIC promotes sustained motivated responding more generally.

RESUMO

Emotionally salient experiences are encoded and remembered more strongly, an effect that can be amplified by hormones like cortisol. Such memories can in turn profoundly influence later behavior. However, little is known about the link between amplified salience encoding and subsequent behavior. This pathway may be particularly important for risky alcohol drinking, which has been linked to sensitized salience responses, memory, and cortisol. To test this possibility, we integrated pharmacology using a double-blind cross-over design with fMRI, cognitive, and motivation assays across a range of healthy male and female social drinkers. As anticipated, cortisol enhanced memory for salient alcohol-related events; critically, this bias was in turn associated with later alcohol motivation. Increased alcohol motivation was particularly pronounced in more susceptible risky drinkers, for whom cortisol enhanced brain salience responses to alcohol. These sensitized salience responses predicted both memory biases and alcohol motivation. Together, these findings reveal maladaptive consequences of enhanced salience encoding.

RESUMO

The adverse psychological and social impacts of COVID-19 pandemic are well characterized, but the role of composite, modifiable lifestyle factors that may interact to mitigate these impacts is not. The effect of socioeconomic deprivation on these lifestyle risks also remains unclear. Based on a nationally representative, longitudinal cohort, we assessed the association between a combination of pre-pandemic lifestyle factors and mental health conditions during pandemic, and the contribution of deprivation to it. Composite lifestyle factors included BMI, smoking status, alcohol consumption, physical activity, sedentary time, sleep duration, and fruit and vegetable intake, with lifestyle scores and lifestyle categories calculated for each participant. Symptoms of depression and anxiety, and personal well-being were assessed by validated scales during the pandemic. Socioeconomic deprivation was characterized by both individual-level (income, wealth, and education) and group-level factors (Index of Multiple Deprivation). Of the 5049 eligible participants (mean [SD] age, 68.1 [10.9] years; 57.2% were female) included in the study, 41.6% followed a favorable lifestyle, 48.9% followed an intermediate lifestyle, and 9.5% followed an unfavorable lifestyle. Compared with favorable lifestyle category, participants in the intermediate and unfavorable lifestyle category were at increased risk of mental health conditions, with the hazard ratio (HR) for trend per increment change towards unfavorable category of 1.17 (95% CI 1.09-1.26) for depression, 1.23 (1.07-1.42) for anxiety, and 1.39 (1.20-1.61) for low well-being. A significant trend of lower risk for mental health conditions with increasing number of healthy lifestyle factors was observed (P < 0.001 for trend). There were no significant interactions between lifestyle factors and socioeconomic deprivation for any of the outcomes, with similar HRs for trend per one increment change in lifestyle category observed in each deprivation group. Compared with those in the least deprived group with favorable lifestyle, participants in the most deprived group adherent to unfavorable lifestyle had the highest risk of mental health outcomes. These results suggest that adherence to a broad combination of healthy lifestyle factors was associated with a significantly reduced risk of mental health conditions during the COVID-19 pandemic. Lifestyle factors, in conjunction with socioeconomic deprivation, independently contribute to the risk of mental health issues. Although further research is needed to assess causality, the current findings support public health strategies and individual-level interventions that provide enhanced support in areas of deprivation and target multiple lifestyle factors to reduce health inequalities and promote mental well-being during the ongoing COVID-19 pandemic.

RESUMO

In this narrative review, we draw from historical and contemporary literature to explore the impact of alcohol consumption on brain and behavior among women. We examine three domains: 1) the impact of alcohol use disorder (AUD) on neurobiobehavioral outcomes, 2) its impact on social cognition/emotion processing, and 3) alcohol's acute effects in older women. There is compelling evidence of alcohol-related compromise in neuropsychological function, neural activation, and brain structure. Investigations of social cognition and alcohol effects in older women represent emerging areas of study. Initial analyses suggest that women with AUD show significant deficits in emotion processing, a finding also observed in older women who have consumed a moderate dose of alcohol. Critically, despite the long-recognized need for programmatic interrogation of alcohol's effect in women, studies with sufficient numbers of women for meaningful analysis represent a small proportion of the literature, constraining interpretation and generalization.

RESUMO

The cognitive impairments that are often observed in patients with alcohol use disorder (AUD) partially contribute to the extremely low rates of treatment initiation and adherence. Brain acetylcholine receptors (AChR) mediate and modulate cognitive and reward-related behavior, and their distribution can be altered by long-term heavy drinking. Therefore, AChRs are promising pharmacotherapeutic targets for treating the cognitive symptoms of AUD. In the present study, the procognitive efficacy of two AChR agonists, xanomeline and varenicline, were evaluated in group-housed monkeys who self-administered ethanol for more than 1 year. The muscarinic AChR antagonist scopolamine was used to disrupt performance of a serial stimulus discrimination and reversal (SDR) task designed to probe cognitive flexibility, defined as the ability to modify a previously learned behavior in response to a change in reinforcement contingencies. The ability of xanomeline and varenicline to remediate the disruptive effects of scopolamine was compared between socially dominant and subordinate monkeys, with lighter and heavier drinking histories, respectively. We hypothesized that subordinate monkeys would be more sensitive to all three drugs. Scopolamine dose-dependently impaired performance on the serial SDR task in all monkeys at doses lower than those that produced nonspecific impairments (e.g., sedation); its potency did not differ between dominant and subordinate monkeys. However, both AChR agonists were effective in remediating the scopolamine-induced deficit in subordinate monkeys but not in dominant monkeys. These findings suggest xanomeline and varenicline may be effective for enhancing cognitive flexibility in individuals with a history of heavy drinking. SIGNIFICANCE STATEMENT: Procognitive effects of two acetylcholine (ACh) receptor agonists were assessed in group-housed monkeys who had several years' experience drinking ethanol. The muscarinic ACh receptor agonist xanomeline and the nicotinic ACh receptor agonist varenicline reversed a cognitive deficit induced by the muscarinic ACh receptor antagonist scopolamine. However, this effect was observed only in lower-ranking (subordinate) monkeys and not higher-ranking (dominant monkeys). Results suggest that ACh agonists may effectively remediate alcohol-induced cognitive deficits in a subpopulation of those with alcohol use disorder.

RESUMO

BACKGROUND: Machine learning could predict binge behavior and help develop treatments for bulimia nervosa (BN) and alcohol use disorder (AUD). Therefore, this study evaluates person-specific and pooled prediction models for binge eating (BE), alcohol use, and binge drinking (BD) in daily life, and identifies the most important predictors. METHODS: A total of 120 patients (BN: 50; AUD: 51; BN/AUD: 19) participated in an experience sampling study, where over a period of 12 months they reported on their eating and drinking behaviors as well as on several other emotional, behavioral, and contextual factors in daily life. The study had a burst-measurement design, where assessments occurred eight times a day on Thursdays, Fridays, and Saturdays in seven bursts of three weeks. Afterwards, person-specific and pooled models were fit with elastic net regularized regression and evaluated with cross-validation. From these models, the variables with the 10% highest estimates were identified. RESULTS: The person-specific models had a median AUC of 0.61, 0.80, and 0.85 for BE, alcohol use, and BD respectively, while the pooled models had a median AUC of 0.70, 0.90, and 0.93. The most important predictors across the behaviors were craving and time of day. However, predictors concerning social context and affect differed among BE, alcohol use, and BD. CONCLUSIONS: Pooled models outperformed person-specific models and the models for alcohol use and BD outperformed those for BE. Future studies should explore how the performance of these models can be improved and how they can be used to deliver interventions in daily life.

RESUMO

OBJECTIVES: As part of a wider study describing the impact of a breast cancer diagnosis on lifestyle behaviours, this paper describes the impact of a breast cancer diagnosis on alcohol consumption and factors influencing consumption. METHODS: Cross-sectional online survey of 140 people (138 women) and interviews with 21 women diagnosed with breast cancer in the last 10 years. RESULTS: Of the 100 survey participants who drank alcohol 25% were drinking at increasing or higher risk levels and 17% strongly wanted to change their drinking behaviour. The habitual aspects of alcohol consumption were the strongest predictor of current alcohol consumption behaviours. Social norms and perceptions about conflicting information were substantial barriers to change. CONCLUSIONS: Breast cancer survivors need accurate information about the risks of alcohol consumption and guidelines in order to make informed decisions about making changes to their behaviour. Interventions to support breast cancer survivors to reduce alcohol consumption need to focus on the development of healthy habits and may benefit from a focus which includes partners and friends.

RESUMO

BACKGROUND: Stress is a common part of college students' daily lives that may influence their physical activity (PA) and alcohol use. Understanding features of daily stress processes that predict health behaviors could help identify targets for just-in-time interventions. PURPOSE: This study used intensive longitudinal data to examine whether prior day stress processes predict current day PA or alcohol use. METHODS: Participants (N=58, Mage=20.5, 59% women, 70% White) were 18-to-25-year-old students who engaged in binge drinking at least twice monthly and used cannabis or tobacco in the past year. They wore activity (activPAL4) and alcohol (Secure Continuous Remote Alcohol Monitor) monitors for 11 days to assess daily PA (e.g., step counts) and alcohol use (e.g., drinking day), and completed daily surveys about yesterday's stress, including number of stressors (i.e., frequency), stressor intensity (i.e., severity), and frequency of affective states (e.g., guilt). Multilevel models examined prior day stress predicting current day PA or alcohol use. RESULTS: Participants had higher odds of current day drinking (odds ratio=1.21) and greater area under the curve (B=0.08) when they experienced greater than usual stress severity the prior day. Participants had higher current day peak transdermal alcohol concentration (B=0.12) and area under the curve (B=0.11) when they more frequently experienced guilt due to stressors the prior day. CONCLUSIONS: College students' unhealthy response of increasing alcohol use due to stress could adversely impact health outcomes. There is a critical need for interventions addressing students' ability to effectively manage and respond to the stress-inducing, daily demands of student life.


College students experience stress regularly, which may influence their physical activity (PA) and drinking behaviors. Understanding how daily stress predicts health behaviors could be useful for stress-reduction interventions. This study examined whether prior day stress predicted current day PA or alcohol use. Participants (N = 58) were 18- to 25-year-old college students who binge drank at least twice per month and used cannabis or tobacco in the past year. They wore PA and alcohol sensors for 11 days to assess daily PA and alcohol use, and completed daily surveys about yesterday's stress, including the number of stressors experienced (i.e., frequency), stressor intensity (i.e., severity), and mood responses related to stress (anger, anxiety, guilt, sadness). Participants were 21% more likely to drink and drank at higher intensity when they experienced greater than usual stress severity the prior day. Participants had higher current day alcohol use intensity when they more frequently experienced guilt due to stressors the prior day. College students' unhealthy response of increasing alcohol use due to stress could negatively impact short- and long-term health outcomes. There is a critical need for interventions addressing students' ability to effectively manage and respond to the stress-inducing, daily demands of student life.

RESUMO

BACKGROUND: Solitary drinking is a risky drinking pattern associated with increased substance use and psychosocial problems. However, very little is known regarding the associations between drinking alone and broader health status and behaviors. PURPOSE: Accordingly, this study examined the relationship between health metrics and solitary drinking among individuals who currently drink (N = 99, 46.46% female, 88.89% White). METHODS: U.S. participants between 21 and 40 years old were recruited. Measures included self-reported diet, physical activity, sleep, cannabis use, general and solitary alcohol use, and objective anthropomorphic measures (e.g., body mass index [BMI]) using data from both a baseline appointment and 30 days of daily diary responses. Adjusting for general alcohol use, age, and gender, associations at baseline were assessed through regression analyses, while daily data were analyzed via mixed effects models. RESULTS: Several health measures were associated with solitary drinking. Specifically, solitary drinking was related to consuming fewer servings of fruits and vegetables and greater quantities of alcohol based on daily data. Baseline data showed an association between solitary drinking and higher BMIs, poorer sleep quality, greater sugar consumption, and hazardous drinking. CONCLUSIONS: These findings suggest that beyond substance and psychosocial problems associated with solitary drinking, this drinking behavior may be a warning sign for health risks and, subsequently, broader health problems.


Associations between health metrics and lifetime solitary drinking were examined among individuals who currently drink alcohol (N = 99, 46.46% female, 88.89% White). Solitary drinking was related to less fruit and vegetable consumption, greater sugar consumption, more hazardous drinking, poorer sleep quality, and higher body mass index. Findings suggest that solitary drinking may be a warning sign for health risks and, subsequently, broader health problems.

RESUMO

BACKGROUND AND PURPOSE: Minority stressors have been linked with alcohol use among transgender and gender diverse (TGD); however, no ecological momentary assessment studies have examined daily links between minority stress and alcohol use specifically among TGD. This study examined gender minority stressors and resilience as predictors of same-day or momentary alcohol-related outcomes. Feasibility and acceptability of procedures were evaluated. METHODS: Twenty-five TGD adults (mean age = 32.60, SD = 10.82; 88% White) were recruited Canada-wide and participated remotely. They completed 21 days of ecological momentary assessment with daily morning and random surveys (assessing alcohol outcomes, risk processes, gender minority stressors, resilience), and an exit interview eliciting feedback. RESULTS: Gender minority stress had significant and positive within-person relationships with same-day alcohol use (incidence risk ratio (IRR) = 1.12, 95% confidence interval [CI] [1.02, 1.23]), alcohol-related harms (IRR = 1.14, 95% CI [1.02, 1.28]), and coping motives (IRR = 1.06, 95% CI [1.03, 1.08]), as well as momentary (past 30-min) alcohol craving (IRR = 1.32, 95% CI [1.18, 1.47]), coping motives (IRR = 1.35, 95% CI [1.21, 1.51]), and negative affect (IRR = 1.28, 95% CI [1.20, 1.36]). Gender minority stress indirectly predicted same-day drinking via coping motives (ab = 0.04, 95% CI [0.02, 0.08]). Resilience was positively associated with same-day alcohol use (IRR = 1.25, 95% CI [1.03, 1.51]) but not harms. CONCLUSIONS: TGD adults may use alcohol to cope with gender minority stress, which can increase the risk for alcohol-related harms. Interventions are needed to eliminate gender minority stressors and support adaptive coping strategies.


Many transgender and gender diverse (TGD) adults experience discrimination and victimization related to their minoritized gender, referred to as minority stress. Minority stress may put TGD adults at risk of drinking more alcohol and experiencing related harms in order to cope. To examine this possibility, we recruited 25 TGD adults and asked them to complete surveys multiple times per day (i.e., once daily in the morning, and two additional surveys at random times) on their personal cell phones. Using multilevel models, we examined the relations between experiencing minority stressors as well as resilience factors on alcohol-related outcomes. In doing so, we identified that gender minority stress was related to increased alcohol use, alcohol-related harms, negative mood, and drinking to cope motives. Furthermore, it appeared that the increased alcohol use following minority stress could be partly explained by desiring to drink to cope. Resilience did not protect TGD adults from increased alcohol use or harms, and in some cases was related to increased alcohol use. The results support that TGD adults may use alcohol to cope with gender minority stress, which can increase the risk for alcohol-related harms. Interventions are needed to eliminate gender minority stressors and support healthier coping strategies.

RESUMO

Social events and stressful settings can be catalysts for alcohol consumption. Motivational enhancement therapy (MET) and cognitive behavioral therapy (CBT) are widely used in alcohol interventions. We assessed how alcohol consumption varied across three types of days (positive/social, negative/stressful, and neutral) among hazardous alcohol users living with HIV in Vietnam. We further evaluated how those consumption patterns changed after two MET/CBT alcohol reduction interventions versus the standard of care (SOC). The 'combined' intervention offered 6 individual sessions and 3 group sessions; the 'brief' intervention offered 2 individual sessions and 2 phone calls. A 30-day timeline follow-back was administered at study visits, detailing daily drinks and events. Days were categorized as neutral, positive/social, or negative/stressful; negative binomial models and generalized estimating equations were used to estimate drinks consumed by type of day at baseline and 12 months. Prior to intervention, more drinks were consumed on positive/social days (5.2 drinks; 95% Confidence Interval [CI]:4.8, 5.7) than negative/stressful (1.5; 95% CI:1.3, 1.9) and neutral days (2.2; 95% CI: 1.9, 2.5). After the brief intervention, drinks consumed decreased on neutral days (ratio: 0.5: 95% CI: 0.4, 0.7). After the combined intervention, drinks consumed decreased on neutral days (ratio: 0.4; 95% CI: 0.3, 0.6), positive/social days (ratio: 0.6; 95% CI: 0.5, 0.7) and negative/stressful days (ratio: 0.3; 95% CI: 0.2, 0.6). No reductions in consumption were observed in the SOC group. Social/positive days had the highest alcohol consumption prior to intervention, and the combined intervention showed the greatest decrease in consumption on those days. CLINICAL TRIAL REGISTRATION: The study is registered at clinicaltrials.gov (NCT02720237).

RESUMO

In Sub-Saharan Africa, efficacy trials of brief interventions to reduce unhealthy drinking among persons living with HIV (PLWH) have yielded mixed results. A better understanding of the perceptions of drinking, especially by PLWH, and how drinking is talked about at HIV treatment clinics in this setting, may guide more optimal designs for future trials. We conducted a qualitative study at an HIV treatment clinic in South Western Uganda to better understand perceptions of drinking, how drinking is talked about, and perceptions of interventions, especially a protocolled screening and brief intervention (SBI) for unhealthy drinking among PLWH. We conducted in-depth interviews with 17 PLWH who engaged in unhealthy drinking and 6 health workers, and one focus group discussion with 3 community advisory-board members. We performed manual preliminary data analysis and computer-assisted detailed thematic analysis to identify emergent themes. Four themes emerged: perceptions of alcohol use in the general population; perceptions of alcohol use in PLWH; interaction between PLWH and health workers about alcohol use; perceptions of interventions for unhealthy drinking including SBI. Unhealthy drinking was seen as a problem in the general population and among those with HIV, where it was negatively perceived. Communication about drinking was done by counselors, but doctors participated in screening for unhealthy alcohol use. Messages about drinking covered reduction and abstinence. Participants expressed positive attitudes towards SBI and preference for person-delivered SBI over technological alternatives. A protocolled SBI for unhealthy alcohol use among PLWH would be well-received but successful implementation may depend on mode of delivery.

RESUMO

Alcohol use is an important factor in achieving and maintaining viral suppression and optimal mental health among persons with HIV (PWH), however, the effect of age at first regular drinking on viral suppression and depression remains poorly understood. Here, using secondary data from the Alcohol Drinkers' Exposure to Preventive Therapy for Tuberculosis (ADEPT-T) study, we used logistic regression analyses to explore whether there is an association between age at first regular drinking and viral suppression (< 40 copies/ml), or presence of depressive symptoms (Center for Epidemiologic Studies Depression, CES-D ≥ 16) among 262 PWH. The median age at first regular drinking was 20.5 years (IQR: 10), with high proportions starting under age 12 (12.2%) and as teens (13.4%). The majority had an undetectable viral load (91.7%) and 11% had symptoms of probable depression. We found no significant association between age at first regular drinking and viral suppression (i.e., child (aOR = 0.76 95%CI: 0.18, 3.26), adolescent (aOR = 0.74 95%CI: 0.18, 2.97) and young adult (aOR = 1.27 95%CI: 0.40, 3.97)) nor with depressive symptoms (i.e., child (aOR = 0.72 95%CI: 0.19, 2.83), adolescent (aOR = 0.59 95%CI: 0.14, 2.50) and young adult (aOR = 0.57 95%CI: 0.22, 1.53)). Age at first regular drinking among PWH did not appear to be associated with either viral suppression or the presence of depressive symptoms, suggesting interventions may best be focused on the harmful effects of current alcohol use.

RESUMO

Although alcohol use is associated with depression, it is unclear if brief alcohol reduction interventions can ameliorate depression and psychological distress among people with HIV (PWH). We use data from a two-arm randomised controlled trial to examine this question. PWH on antiretroviral treatment (ART) were randomly assigned to receive a brief intervention or treatment as usual (n = 622). Screening was done with the Alcohol Use Disorders Identification Test (AUDIT), AUDIT-C, Centre for Epidemiological Studies Depression inventory and Kessler Psychological Distress Scale, at baseline and at 3- and 6-months post-baseline. Changes in depression and psychological distress was assessed using analysis of covariance models with baseline measures of alcohol consumption, sex and age included as covariates and adjusting for baseline symptom severity. Changes in alcohol consumption between baseline and follow-up were included in the analysis to establish if this affected outcomes. For both the intervention and control groups, there were significant reductions in symptom severity at 3-months and 6-months for depression and psychological distress, but no significant between group differences were observed. Reductions in alcohol consumption were significantly associated with reductions in depression and psychological distress, supporting the hypothesis that alcohol use is linked to depression among PWH.Trial Registration Pan African Clinical Trials Register, PACTR201405000815100.nh.

RESUMO

We evaluated the feasibility, acceptability, and preliminary efficacy of an economic and relationship-strengthening intervention to reduce heavy alcohol use among couples living with HIV in Malawi (Mlambe). Mlambe consisted of training on financial literacy and relationship skills, combined with 1:1 matched savings accounts to invest in an income-generating activity. In a randomized controlled trial, we compared Mlambe to enhanced usual care (EUC). We enrolled 78 married couples having a partner on antiretroviral therapy (ART) who reported heavy alcohol use based on the AUDIT-C. Using targets of 75%, primary outcomes included retention rates at 10 and 15-months, session attendance rates, and satisfaction with Mlambe. Exploratory outcomes were heavy alcohol use (AUDIT-C and/or PEth positive), number of drinking days in the past month, AUDIT-C score, optimal adherence to ART (95% or higher), and viral suppression. We exceeded our targets for feasibility and acceptability metrics. Retention rates were 96% at 15-months. Session attendance and satisfaction levels were both 100%. From baseline to 15-months, Mlambe participants reported decreases in mean number of drinking days (from 6.8 to 2.1) and AUDIT-C scores (from 7.5 to 3.1); while ART adherence rates improved across the same period (from 63.2 to 73.9%). Participants in Mlambe, as compared to those in EUC, had lower rates of heavy alcohol use (89.5% vs. 97.2%) and higher rates of viral suppression (100% vs. 91.9%) at 10-months. Differences between arms were not statistically significant in this small pilot study. Mlambe was highly feasible and acceptable, and shows promise for reducing heavy alcohol use and viral non-suppression among couples with HIV in a larger efficacy study.

RESUMO

U.S. Veterans and people living with HIV (PWH) experience higher rates of unhealthy alcohol and tobacco/nicotine use than non-Veterans and people without HIV (PWoH). Both groups are susceptible to adverse health outcomes associated with alcohol and tobacco/nicotine use. We explored awareness of alcohol- and tobacco/nicotine-related cancer and immune health risks among Veterans Health Administration (VA) patients with and without HIV. Among a sample of 41 (46% PWH; 73% male; 39% Black) purposively-selected VA patients receiving care 2020-2021 we conducted semi-structured interviews via telephone; interviews were recorded, transcribed and analyzed using a Rapid Assessment Process. Purposive selection was based on HIV status, alcohol and/or tobacco/nicotine use, and demographics. Among participants, 66% reported current smoking, and most screened positive for unhealthy alcohol use. Participants had high awareness of cancer and other health risks related to smoking but low awareness of synergistic risks and cancer risks associated with alcohol use despite awareness of a range of other alcohol-related risks. Awareness of alcohol and/or tobacco/nicotine's impacts on the immune system was variable. Findings did not distinctly differ between PWH and PWoH. Low awareness of alcohol-related cancer risk, risks of co-occurring use, and varying awareness of the impacts of alcohol and tobacco/nicotine on the immune system suggest a need for improved messaging regarding substance use-related cancer and immune risk. This may be especially important among PWH, for whom the prevalence and adverse effects of alcohol and tobacco use, and immune dysfunction are higher.

RESUMO

Adverse childhood experiences (ACEs) and financial hardship are associated with increased likelihood of heavier alcohol use and health challenges in adulthood among persons living with HIV (PWH). We examined whether retrospectively captured lifetime drinking trajectories are a pathway through which childhood hardships affect current health in a sample of 365 adult PWH. Childhood economic hardship and ACEs were used as main predictors. Measures of alcohol use included age at first drink and lifetime drinking trajectories. Health indicators included health-related quality of life, frailty, number of comorbidities, and symptoms of anxiety, depression, and post-traumatic stress disorder (PTSD). Structural equation modeling (SEM) was applied to estimate both direct and indirect pathways between childhood hardship and physical and mental health. Participants were mostly male; Black (84%); and averaged 48 years of age. SEM results supported both direct and indirect pathways between childhood experiences and adult health. ACEs were connected to physical health directly and mental health both directly and indirectly through age at first drink and drinking heaviness during ages 10-20. Childhood economic hardship related to mental health indirectly through higher drinking levels during ages 10-20. Childhood adverse experiences, economic hardship, and early drinking patterns appear to accumulate, resulting in later life physical and mental health concerns for PWH. Findings support taking a life course approach to health. This includes considering individual trauma histories in HIV care engagement and taking preventative approaches which support the economic and social well-being of vulnerable children to improve health in subsequent decades.

RESUMO

Multilevel factors (individual and structural) influence adherence to antiretroviral therapy, particularly in high HIV prevalence areas such as South Africa. The present study examined the relative importance of structural barriers to HIV care and behavioral health factors, depression and alcohol use, in Khayelitsha, Cape Town, South Africa. People receiving HIV care in six primary care clinics in Khayelitsha (N = 194) completed the Center for Epidemiologic Studies Depression Scale, the Alcohol Use Disorders Identification Test, the Structural Barriers to Medication Taking questionnaire, and a qualitative rating of past-two-week adherence. Correlations were employed to examine associations among these variables, and hierarchical regression analysis was used to examine the unique effects of structural barriers over and above depression and alcohol use as predictors of adherence. Participants were primarily Black South African (99%) women (83%), and 41 years old on average. All four variables were significantly correlated. The hierarchical regression analysis showed that among behavioral health predictors, alcohol use alone significantly predicted ART adherence (b = -.032, p = .002). When structural barriers was added to the model, it was the only significant unique predictor of ART adherence (b = -1.58, p < .001). Findings highlight the need to consider structural vulnerabilities in HIV care in South Africa when developing behavioral health interventions.

RESUMO

BACKGROUND: Relapse remains the major challenge in treatment of alcohol use disorder (AUD). Aberrant decision-making has been found as important cognitive mechanism underlying relapse, but factors associated with relapse vulnerability are unclear. Here, we aim to identify potential computational markers of relapse vulnerability by investigating risky decision-making in individuals with AUD. METHODS: Forty-six healthy controls and fifty-two individuals with AUD were recruited for this study. The risk-taking propensity of these subjects was investigated using the balloon analog risk task (BART). After completion of clinical treatment, all individuals with AUD were followed up and divided into a non-relapse AUD group and a relapse AUD group according to their drinking status. RESULTS: The risk-taking propensity differed significantly among healthy controls, the non-relapse AUD group, and the relapse AUD group, and was negatively associated with the duration of abstinence in individuals with AUD. Logistic regression models showed that risk-taking propensity, as measured by the computational model, was a valid predictor of alcohol relapse, and higher risk-taking propensity was associated with greater risk of relapse to drink. CONCLUSION: Our study presents new insights into risk-taking measurement and identifies computational markers that provide prospective information for relapse to drink in individuals with AUD.

RESUMO

BACKGROUND: The activation of permissive beliefs is a cognitive mechanism through which individuals permit themselves to engage in pleasurable, yet potentially unregulated activities. Existing measures are heterogenous, focusing either on specific behaviors or on particular licensing mechanisms. The new Permissive Beliefs Questionnaire (PBQ) seeks to integrate self-licensing mechanisms from various research domains and to be applicable to different behaviors. METHODS: Study 1 aimed at exploring the factor structure and reduce the number of items. In study 2, we used confirmatory factor analysis and tested convergent and discriminant validity in three subsamples of individuals playing videogames (n = 489), shopping online (n = 506), and drinking alcohol (n = 511). We tested the hypothesis whether individuals who experience a self-regulatory conflict show a greater expression of permissive beliefs. RESULTS: The final version of the PBQ consists of 12 items which represent two factors: Deserving Reward and Defensive Optimism. The PBQ exhibited robust model fit indices and internal consistencies in the three samples. Permissive beliefs were heightened among individuals intending to downregulate their gaming, shopping, or drinking behaviors as compared to individuals without this intention. CONCLUSION: The PBQ is a valid measure of permissive beliefs for gaming, online shopping, and drinking alcohol. It serves an ecologic and psychometrically valid tool to address empirical research questions regarding the functioning of permissive beliefs. Additionally, it may be used in clinical settings to measure and raise an understanding for permissive beliefs in clients.
