A time-varying effect model of the dynamic association between alcohol use and consequences over the first two years of college

Examining Demographic & Socio-Cultural Factors as Predictors of Alcohol Consumption Among African American Male College Students Attending an Urban Historically Black College and University

Alcohol consumption among college students continues to be a significant public health concern for colleges and universities across the country. However, a preponderance of research primarily included White samples from predominantly white institutions. Unsurprisingly, this practice limits what is known regarding alcohol consumption among African American male college students on historically Black campuses. Notably, as a "rite of passages" from childhood to adulthood, early exposure to alcohol consumption has been viewed as a cultural norm in African American families. The negative consequences associated with alcohol abuse, early exposure to alcohol, and the prevalence of problem drinking among college students in general, mandated further research facilitating a better understanding of this public health concern on historically Black campuses. This study examined alcohol use among African American male college students, investigating relationships between demographics and socio-cultural factors as predictors of alcohol consumption among African American male college students who drink. A convenience sample of 94 students was used. A multiple regression was conducted to test whether demographics and socio-cultural factors were predictors of alcohol consumption. Findings from this study will advance social work research and stimulate discussions about substance abuse disparities among African American male college students who consume alcohol. Furthermore, this research highlights the public health issue, prompting the development of prevention and intervention programs aimed at addressing the social problem of alcohol consumption among African American male college students at historically Black universities.

Evaluating the association between lifestyle factors and heel bone mineral density in different inflammatory states

Rationale

It is unclear whether lifestyle factors affect bone mineral density (BMD) during different inflammatory states.

Objective

This study investigated the effects of coffee consumption, vitamin D (VD) intake, smoking, and alcohol consumption on heel BMD in adults with different inflammatory states.

Methods

The phenotypic data from 249,825 participants were analyzed using the UK Biobank cohort. The inflammatory status was evaluated using C-reactive protein (CRP) levels and the systemic immune-inflammation index. Linear regression analysis was used to examine the association between coffee consumption, VD, smoking, alcohol consumption, and heel BMD in adults with different inflammatory states. Linear regression models were used to analyze the interaction between inflammation and the four lifestyle factors with respect to their influence on heel BMD in adults.

Results

Our findings revealed that VD was positively associated with adult heel BMD (β = 2.41 × 10-2, SE = 5.14 × 10-3, P = 2.72 × 10-6), while alcohol consumption and smoking were negatively associated with adult heel BMD. Coffee was negatively associated with adult heel BMD in low inflammatory states (β = -1.27 × 10-2, SE = 4.79 × 10-3, P = 8.00 × 10-3), while there was no association between coffee and adult heel BMD in high inflammatory states. Overall, it was found that these four lifestyle factors interacted negatively with inflammatory states.

Conclusion

Our study suggests that VD is positively associated with adult heel BMD and that alcohol consumption and smoking are negatively associated with adult heel BMD. Coffee may reverse the adverse effects of inflammation on BMD when the patient is in a highly inflammatory state, thus acting as a protective agent against heel BMD in adults.

Where do heavy drinking college students experience alcohol consequences and where are they perceived to be normative?

High levels of alcohol consumption are common among college students and associated with endorsing negative alcohol-related consequences. Research suggests both drinking norms and location are strong predictors of drinking behavior in college students. Yet, normative perceptions of consequences, and whether they are location-specific, are less well-studied. We tested the hypotheses that college students who drink would have the highest levels of descriptive and injunctive norms for negative consequences, and would self-report the greatest number of negative consequences, at large gatherings/parties relative to someone's home/dorm and/or bars/clubs. Additionally, we explored whether specific acute consequences were more likely in some drinking locations versus others. Participants were 96 full-time undergraduate students who engaged in high-risk drinking. At baseline, participants reported descriptive and injunctive norms for negative consequences in three locations (home/dorm, large gathering/party, bar/club). Over a 28-day period, participants self-reported daily experiences of five alcohol-related consequences in these same locations. With repeated measures analyses of variance, we found that participants perceived their peers experienced more negative consequences and were more approving of negative consequences at large gatherings/parties and small gatherings at someone's home/dorm relative to bars/clubs. Likewise, nonparametric analyses demonstrated that the total number of consequences over the 28-day assessment period also differed by location, with participants reporting more consequences at home/dorm and large gathering/party locations than at bars/clubs. Future research is needed to better understand how the impact of norms on behavior differs across drinking location, and whether location-specific intervention content (e.g., normative correction) would be useful.

Australian first-year university college residents’ alcohol consumption and alcohol-related harms

Aim: The study sought to develop an understanding of Australian first-year university residential college students’ alcohol consumption, their experience of alcohol-related harms and their alcohol knowledge. Method: Students were surveyed during Orientation Week in 2015 (N = 84, men 36%) and again in 2017 (N = 97, men = 45%) using the Alcohol Use Disorders Identification Test (AUDIT) to measure alcohol consumption, and purpose-designed measures of alcohol-related harms and alcohol knowledge. Results: The mean AUDIT score across the two cohorts was 10.79, placing these first-year college residents at much riskier consumption levels than their Australian undergraduate and international peers. Three-quarters were consuming alcohol at hazardous/harmful levels. They reported frequent occurrence of alcohol-related harms and, given the higher levels of drinking, these were for the most part more pronounced than in other studies: vomiting (73%), memory loss (55%), regretting their actions when drinking (41%), not having enough money because of money spent on alcohol (31%), doing something dangerous just for fun (29%), being injured (27%), poor performance at work (22%), poor physical health (21%), loss of consciousness (20%), and having sexual encounters they later regretted (19%). Poor knowledge of standard drink measures, particularly in relation to blood alcohol concentration, was also indicated. Conclusions: The study highlights the worrying occurrence of hazardous/harmful drinking in Australian first-year university residential college students and high levels of alcohol-related harms experienced by these residents. It also highlights poor alcohol knowledge and the need for early intervention prior to and within university college residences to minimise harm.

A Comparison Between Ecological Momentary Assessment and the Adapted-Quick Drinking Screen: Alcohol Mixed With Energy Drinks

Aims

To compare alcohol consumption and risk-taking behaviours on alcohol mixed with energy drink (AMED) and alcohol-only (AO) drinking occasions collected via ecological momentary assessment (EMA) versus retrospective survey methods (adapted-Quick Drinking Screen: a-QDS).

Methods

Completing participants were 52 university students who reported AMED consumption during the 30-day data collection period. Alcohol consumption and risk-taking behaviours were captured for recreational AMED and AO consumption occasions using a smartphone-based app across 30 days. Data were aggregated for comparison with the a-QDS conducted at the end of data collection.

Results

Irrespective of data collection method, alcohol was consumed more frequently and at higher quantities on the heaviest drinking occasions when consumed alone compared with when it was mixed with energy drinks. Consistent with this finding, more risk-taking behaviours were experienced on AO occasions compared with AMED occasions. Compared with the a-QDS, the quantity of alcohol consumed on the average and heaviest drinking occasion was significantly higher when reported via EMA. This was consistent across both AO and AMED drinking occasions.

Conclusion

EMA provides a more valid measure of consumption quantity compared with retrospective recall, which was susceptible to under-reporting, although this was not differentially affected across consumption occasions. In line with previous research, this study demonstrated that mixing alcohol with energy drinks does not increase alcohol consumption or risk-taking behaviours.

When are alcohol-related blackout Tweets written in the United States?

BACKGROUND

Alcohol use varies throughout the year and often peaks on weekends or during celebrations (e.g., New Year's). There is not a perfect correlation between alcohol use and negative consequences, and the extent to which one particularly risky consequence-an alcohol-related blackout-is more common during certain times of the year is unknown. Identifying when blackouts occur may help identify which periods are associated with more risk and be critical in designing public health campaigns. Thus, we examined Twitter data to ascertain whether alcohol-related blackouts occur more during certain holidays/celebrations than typical weekends and whether they differed in timing from general alcohol-related Tweets.

METHODS

We used a Twitter-sponsored platform to access unique Tweets written in the United States referencing blackouts (e.g., "blackout") and alcohol generally (e.g., "drunk").

RESULTS

The final dataset included 3.5 million blackout Tweets and 591 million alcohol Tweets (written between 2009 and 2020). Both blackout and alcohol Tweets were written in the late evening, on weekends, and during certain holidays (New Years, St. Patrick's). However, relative to typical weekends, only blackout Tweets were more common during Thanksgiving and only general alcohol-related Tweets were more common during Cinco de Mayo.

CONCLUSION

While blackout and alcohol-related Tweets were similar in time of day (peaking in the evening) and day of week (peaking on weekends), they differed during certain celebrations/holidays, suggesting that while alcohol use may be more common during some celebrations, others are more associated with serious harms.

Dynamic models of stress-smoking responses based on high-frequency sensor data

Self-reports indicate that stress increases the risk for smoking; however, intensive data from sensors can provide a more nuanced understanding of stress in the moments leading up to and following smoking events. Identifying personalized dynamical models of stress-smoking responses can improve characterizations of smoking responses following stress, but techniques used to identify these models require intensive longitudinal data. This study leveraged advances in wearable sensing technology and digital markers of stress and smoking to identify person-specific models of stress and smoking system dynamics by considering stress immediately before, during, and after smoking events. Adult smokers (n = 45) wore the AutoSense chestband (respiration-inductive plethysmograph, electrocardiogram, accelerometer) with MotionSense (accelerometers, gyroscopes) on each wrist for three days prior to a quit attempt. The odds of minute-level smoking events were regressed on minute-level stress probabilities to identify person-specific dynamic models of smoking responses to stress. Simulated pulse responses to a continuous stress episode revealed a consistent pattern of increased odds of smoking either shortly after the beginning of the simulated stress episode or with a delay, for all participants. This pattern is followed by a dramatic reduction in the probability of smoking thereafter, for about half of the participants (49%). Sensor-detected stress probabilities indicate a vulnerability for smoking that may be used as a tailoring variable for just-in-time interventions to support quit attempts.

An Ecological Momentary Assessment of Affect, Mental Health Symptoms, and Decisions to Drink Among First-Year College Women: A Pilot Study

College women experience more consequences (e.g., blacking out, unprotected/unwanted sex) on days when they engage in their heaviest drinking. To inform prevention efforts, research is needed to understand decision-making processes that influence women's drinking behaviors at the event level. The present study used ecological momentary assessment (EMA) methods to examine: (1) associations between positive affect (PA) and negative affect (NA) and decision-making processes on days leading up to, during, and following heavy drinking events; and (2) mental health symptoms as moderators of these associations. Female undergraduate drinkers (N = 57) completed a 14-day EMA protocol on their smartphones, which included three daily assessments of PA, NA, and willingness and intentions to drink. Trait anxiety and depressive symptoms were measured before the EMA protocol and assessed as moderators. Time-varying effect models were used to examine covariation among PA, NA, and willingness and intentions to drink on the days leading up to participants' heaviest drinking events, the day of the event itself, and the days following the event. Results revealed PA was positively associated with willingness to drink the 2 days before, the day of, and the day after the heaviest drinking event. Similar effects were observed for PA and intentions to drink. Trait anxiety moderated the association between PA and intentions to drink. Findings underscore that positive affect may influence drinking-related decision-making processes surrounding heavy drinking events, particularly in those college women low in anxiety. Results identify potential entry points for real-time intervention efforts targeting college women during times of elevated PA.

Marijuana use is associated with alcohol use and consequences across the first 2 years of college

College entry is associated with marijuana initiation, and co-use of alcohol and marijuana is associated with problematic outcomes, including alcohol-related consequences. The present study explored if: (a) use of marijuana on a given day would be associated with greater alcohol use within the same day; (b) use of marijuana within a given week would be associated with increased alcohol-related consequences in that same week; and (c) the association between marijuana use and alcohol consumption and consequences varies across time or by precollege level of problematic alcohol use. Participants (N = 488 college student drinkers, 59% female) completed assessments of marijuana use, alcohol use, and alcohol consequences across 2 years. Analyses revealed: (a) daily marijuana use predicted greater number of daily drinks and estimated breath alcohol concentration; (b) weekly marijuana use predicted more weekly positive and negative alcohol consequences; (c) the effect of daily marijuana use on alcohol use strengthened over time, while the effect of weekly marijuana use on positive alcohol consequences reduced over time; and (d) precollege level of problematic alcohol use moderated the association between daily marijuana and alcohol use and weekly marijuana use and negative consequences. This study provides the first longitudinal evidence of the association between marijuana use and greater alcohol use and consequences in college students. Future research examining event-level measurement of alcohol and marijuana co-use is important for the prevention of alcohol-related consequences.

Wonderland and the rabbit hole: A commentary on university students' alcohol use during first year and the early transition to university

For new students, university can be a wonderland of opportunity. But the first few weeks of the university experience are also typified by change, stress and uncertainty. From a health promotion perspective, the first few weeks of the university experience present an important yet understudied opportunity for alcohol misuse prevention. In this narrative review, we distinguish students' alcohol use during their first year at university from what is known about their use in the first few weeks on campus. First, we outline the developmental context of the first year experience and the descriptive epidemiology of alcohol use and consequences. Second, we highlight how distinctly different the first few weeks of the university experience are relative to the rest of the academic year and overview the limited research on alcohol use and consequences during the first few weeks. Third, we overview the limited number of strategies that have focused on reducing alcohol use during the transition to university. Finally, we offer a number of suggestions for future research. A better understanding of the nature and determinants of alcohol use and consequences during the transition to university is critical to designing effective prevention and intervention strategies.
