Richards VL, Glenn SD, Turrisi RJ, Mallett KA, Ackerman S, Russell MA. Transdermal alcohol concentration features predict alcohol-induced blackouts in college students. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2024; 48:880-888. [PMID: 38639884 PMCID: PMC11114374 DOI: 10.1111/acer.15290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/31/2024] [Accepted: 02/18/2024] [Indexed: 04/20/2024]
Abstract
BACKGROUND Alcohol-induced blackouts (AIBs) are common in college students. Individuals with AIBs also experience acute and chronic alcohol-related consequences. Research suggests that how students drink is an important predictor of AIBs. We used transdermal alcohol concentration (TAC) sensors to measure biomarkers of increasing alcohol intoxication (rise rate, peak, and rise duration) in a sample of college students. We hypothesized that the TAC biomarkers would be positively associated with AIBs. METHODS Students were eligible to participate if they were aged 18-22 years, in their second or third year of college, reported drinking 4+ drinks on a typical Friday or Saturday, experienced ≥1 AIB in the past semester, owned an iPhone, and were willing to wear a sensor for 3 days each weekend. Students (N = 79, 55.7% female, 86.1% White, Mage = 20.1) wore TAC sensors and completed daily diaries over four consecutive weekends (89.9% completion rate). AIBs were assessed using the Alcohol-Induced Blackout Measure-2. Logistic multilevel models were conducted to test for main effects. RESULTS Days with faster TAC rise rates (OR = 2.69, 95% CI: 1.56, 5.90), higher peak TACs (OR = 2.93, 95% CI: 1.64, 7.11), and longer rise TAC durations (OR = 4.16, 95% CI: 2.08, 10.62) were associated with greater odds of experiencing an AIB. CONCLUSIONS In a sample of "risky" drinking college students, three TAC drinking features identified as being related to rising intoxication independently predicted the risk for daily AIBs. Our findings suggest that considering how an individual drinks (assessed using TAC biomarkers), rather than quantity alone, is important for assessing risk and has implications for efforts to reduce risk. Not only is speed of intoxication important for predicting AIBs, but the height of the peak intoxication and the time spent reaching the peak are important predictors, each with different implications for prevention.

Holmes J, Sasso A, Hernández Alava M, Borges Neves R, Stevely AK, Warde A, Meier PS. How is alcohol consumption and heavy episodic drinking spread across different types of drinking occasion in Great Britain: An event-level latent class analysis. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 127:104414. [PMID: 38588637 DOI: 10.1016/j.drugpo.2024.104414] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 02/23/2024] [Accepted: 03/29/2024] [Indexed: 04/10/2024]
Abstract
BACKGROUND This paper aimed to (i) update a previous typology of British alcohol drinking occasions using a more recent and expanded dataset and revised modelling procedure, and (ii) estimate the average consumption level, prevalence of heavy drinking, and distribution of all alcohol consumption and heavy drinking within and across occasion types. METHODS The paper uses a cross-sectional latent class analysis of event-level diary data that includes characteristics of 43,089 drinking occasions in 2019 reported by 17,821 adult drinkers in Great Britain. The latent class indicators are characteristics of off-trade only (e.g. home), on-trade only (e.g. bar) and mixed trade (e.g. home and bar) drinking occasions. These describe companions, locations, purpose, motivation, accompanying activities, timings, consumption volume in units (1 UK unit = 8g ethanol) and beverages consumed. RESULTS The analysis identified four off-trade only, eight on-trade only and three mixed-trade occasion types (i.e. latent classes). Mean consumption per occasion varied between 4.4 units in Family meals to 17.7 units in Big nights out with pre-loading. It exceeded ten units in all mixed-trade occasion types and in Off-trade get togethers, Big nights out and Male friends at the pub. Three off-trade types accounted for 50.8% of all alcohol consumed and 51.8% of heavy drinking occasions: Quiet drink at home alone, Evening at home with partner and Off-trade get togethers. For thirteen out of fifteen occasion types, more than 25% of occasions involved heavy drinking. Conversely, 41.7% of Big nights out and 16.4% of Big nights out with preloading were not heavy drinking occasions. CONCLUSIONS Alcohol consumption varies substantially across and within fifteen types of drinking occasion in Great Britain. Heavy drinking is common in most occasion types. However, moderate drinking is also common in occasion types often characterised as heavy drinking practices. Mixed-trade drinking occasions are particularly likely to involve heavy drinking.

Abstract
INTRODUCTION The state of Victoria experienced more stringent public health measures than other Australian states during the COVID-19 pandemic. This study investigated how these public health measures impacted: (i) total alcohol consumption; (ii) location-specific consumption; and (iii) consumption among different pre-pandemic drinking groups, in Victoria compared to the rest of Australia during the first year of the pandemic. METHOD A longitudinal study with six survey waves was conducted between April and December 2020. A total of 775 adults completed data on alcohol use, including detailed consumption location information. Based on their 2019 consumption, participants were classified into low, moderate or high-risk groups. Data were analysed descriptively. RESULTS There was no difference in total alcohol consumption from 2019 levels among Victorians and those from the other Australian states when Victoria was the only state in lockdown. Location-specific consumption was relatively similar for Victoria and the rest of Australia, with an increase in home drinking, and a decrease in consumption in someone else's home, licensed premises and public spaces during lockdown compared with 2019. Participants in the high-risk group reported a reduction of two standard drinks per day in November 2020 compared with 2019. In contrast, consumption remained relatively stable for participants in the low and moderate-risk groups once accounting for regression to the mean. DISCUSSION AND CONCLUSION Contrary to expectations, restrictions on licensed premises appeared to impact high-risk drinkers more than low and moderate-risk drinkers. Reducing availability of on-premise alcohol may be an effective way to reduce consumption in heavier drinkers.

THE AMERICAN JOURNAL OF DRUG AND ALCOHOL ABUSE 2023; 49:818-826. [PMID: 38011681 PMCID: PMC10826455 DOI: 10.1080/00952990.2023.2272035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Accepted: 10/13/2023] [Indexed: 11/29/2023]
Abstract
Background: Protective behavioral strategies (PBS) are specific harm reduction behaviors which mitigate alcohol-related consequences among young adults. Prior work indicates PBS utilization varies according to drinking context and gender, suggesting a need for further research assessing whether young adults employ unidentified PBS according to such factors.Objectives: This study examined alcohol PBS young adults suggest using across drinking contexts and gender to inform alcohol-related harm reduction interventions.Methods: An online survey with 514 young adult heavy drinkers (n = 269 female, Mage = 22.36 years) assessed PBS use generally, and across 12 physical and social contexts. We utilized qualitative content analysis methods to code and derive themes from open-ended responses from a prompt asking participants to state additional PBS used per context. The frequency of each theme's appearance was calculated across the overall sample, by gender, and within each context.Results: PBS endorsement varied across context and gender within each theme. Young adults who reported PBS use most frequently endorsed utilizing strategies related to drink content (18.30%), social support (12.36%), and engaging in other activities (10.34%). Participants infrequently endorsed strategies related to awareness of time (0.23%), standards of behavior (0.78%) and avoiding environments (0.87%).Conclusions: Young adults endorse utilizing additional PBS in varying frequency according to drinking context and gender. Given PBS are often a key component of alcohol harm reduction interventions, monitoring trends in young adult PBS use is crucial to ensure continued relevance and efficacy of such interventions to minimize harms associated with young adult heavy alcohol use.

Longitudinal examination of high-risk drinking contexts: Daytime drinking, pregaming, and drinking games linked to high-risk alcohol use and negative consequences in young adults. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2023; 47:1364-1376. [PMID: 37128660 PMCID: PMC10760786 DOI: 10.1111/acer.15095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 04/20/2023] [Accepted: 04/23/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND The contexts in which young adults drink alcohol play a salient role in alcohol-related outcomes and negative consequences at an event-level, but less is known about longitudinal risks. We collected longitudinal monthly data across 2 years on (a) daytime drinking, (b) pregaming/pre-partying, and (c) playing drinking games. We then examined associations between drinking in these contexts and within-person variability in alcohol consumption, consequences, and simultaneous alcohol and marijuana (SAM) use in a given month. We also examined the extent to which drinking in these contexts predicted hazardous drinking (using Alcohol Use Disorders Identification Test (AUDIT) scores) at a distal follow-up timepoint, controlling for baseline AUDIT scores. METHOD A community sample of 759 young adults (Mage = 21.1 years; 56.4% female) completed monthly surveys for 24 consecutive months and a distal 30-month follow-up. Multilevel models estimated within- and between-person associations between drinking context frequencies (daytime drinking, pregaming, drinking games) and alcohol-related outcomes (weekly consumption, consequences, SAM use). A single-level negative binomial regression tested associations between drinking context frequency averages across a two-year period and changes in AUDIT scores from baseline to a follow-up 2.5 years later. RESULTS Over 75% of the sample of non-abstaining young adults reported drinking in each of the three contexts at least once during the 24-month period. Within-persons, young adults reported greater consumption, more negative consequences, and increased likelihood of SAM use during months that they drank in these contexts more often than usual. Each context was associated with negative consequences, even when controlling for alcohol use frequency. More frequent daytime drinking and pregaming, but not drinking games, were associated with increases in AUDIT scores at the 30-month follow-up, suggesting that there are potential long-term risks of drinking in these contexts. CONCLUSIONS Findings suggest that daytime drinking, pregaming, and playing drinking games are high-risk contexts in terms of month-to-month and long-term risks. Additional research is needed on the various contexts in which young adults drink alcohol and the extent to which contextual factors interact with one another to amplify/reduce risks and harms.

Abstract
BACKGROUND Young adults often decide to engage in heavy drinking. Learning more about the real-time factors that predict decisions to initiate a drinking episode and how much is consumed in any single drinking episode is necessary in developing our understanding of momentary alcohol use and discrete decisions surrounding alcohol use. METHODS The current study examined the association between contextual factors and decisions to initiate and consume alcohol in 104 young adult individuals over 2 weeks via mobile daily diary. Participants responded to daily notifications about decisions to drink or not and the contextual factors surrounding each event. The contextual factors included the situation (e.g., bar setting and pregaming) and incentives (e.g., alcohol, social, and mood enhancement). RESULTS Multilevel analyses revealed that incentives predicted both the initiation of drinking and the amount consumed. Event-based alcohol and mood incentives predicted the initiation of drinking, while alcohol, mood, and social/party incentives predicted how much was consumed at a specific event. However, context had a more complex association with drinking outcomes. Being in a bar, alone, or at a residence predicted decisions to initiate drinking, while being in a bar, pregaming situation, or other party situation with others who are drinking predicted how much a person drank. CONCLUSIONS The results highlight the importance of studying event-specific predictors of drinking decisions and the complex association between context/location and the type of drinking decision or outcome.

Abstract
INTRODUCTION The 21st century has seen wide-ranging changes in drinking locations in Great Britain, with on-trade alcohol sales decreasing and off-trade sales increasing. To better understand the underlying time-trends in consumer behaviour, we examine age-period-cohort (APC) effects related to changes in the share of individuals' drinking occasions taking place in: (i) on-trade versus off-trade locations; and (ii) specific on-trade or off-trade locations, that is traditional/community pubs, modern pubs/bars/café bars, nightclubs/late-night venues, restaurants/pub restaurants, social/working men's clubs, golf/other sports clubs/venues, at home (social setting) and at home (non-social setting). METHODS Repeat cross-sectional 1-week drinking diary data, collected 2001-2019. APC analysis via negative binomial regression models for each gender (N = 162,296 men, 138,452 women). RESULTS A smaller/declining proportion of occasions took place in on-trade compared to off-trade locations. Recent cohorts tended to have a larger share of on-trade occasions than previous cohorts, driven by their larger share of occasions in modern pubs/bars/café bars and nightclubs/late-night venues. Meanwhile, occasions in social/working men's clubs, golf/other sports clubs/venues and traditional/community pubs tended to be popular among older men, but have declined. Finally, the growth of off-trade drinking appears to be driven by a growth of off-trade drinking in non-social settings, in particular by older people/cohorts. DISCUSSION AND CONCLUSION Our findings highlight the declining prominence of certain on-trade locations, and increasing prominence of home drinking in non-social settings, within British drinking practices. While rising non-social home drinking is concerning, it is positive from a public health perspective that it does not appear to be shared by recent cohorts.

Abstract
Background: Research has shown that specific contexts are associated with alcohol related problems in adults, but less is known about adolescents. Objectives: We examined how frequencies of drinking in different contexts and the amount of alcohol consumed in these contexts may be related to different alcohol-related problems among adolescent drinkers. Methods: Data were collected through a cross-sectional survey with 377 adolescents (13 to 18 years old) who reported past-6-month alcohol use, sampled from California households. Outcome measures included the breadth of alcohol-related problems participants experienced in the past 6-months overall and in 4 domains (physical, personal, social, and driving under the influence of alcohol or riding with a drunk driver [DUI/RDD]). We also assessed socio-demographics, the number of days adolescents drank alcohol in five contexts (restaurants, own homes, others' homes, outdoors, and fraternities/sororities) and the typical number of drinks they had in each context. Context-specific dose-response models were used to analyze data. Results: In adjusted models, drinking more frequently in outdoor venues was associated with greater number of alcohol-related problems. Drinking frequency in others' homes and in fraternities/sororities was positively associated with a greater number of physical problems. Drinking frequencies in outdoor venues and in others' homes were associated with greater number of personal problems. Finally, drinking more frequently in outdoor venues was associated with greater number of social problems and DUI/RDD. Conclusions/Importance: Results suggest the importance of considering drinking contexts independent of heavier drinking in the context, and they can be used to inform prevention interventions targeting specific risks in relation to alcohol use in specific contexts.KEY POINT SUMMARYThe associations between contexts and drinking problems among adolescents cannot be fully explained by heavier drinking in these contexts.Adolescents' drinking frequencies in specific contexts are uniquely associated with different types of alcohol-related problems.Results inform prevention interventions targeting specific risks in relation to alcohol use in specific contexts among adolescents.

Abstract
BACKGROUND Drinking events are characterized by social and physical contexts that are associated with level of alcohol consumption. Ecologically valid data is needed to delineate aspects of the drinking context that are most likely to precipitate excessive alcohol consumption. METHODS We utilized event-level data from a longitudinal study that included repeated daily surveys administered in two 28-day bursts. Data from 341 college student past-month alcohol and cannabis users (Mage=19.79; 53 % women; 74 % White) produced a total of 4107 alcohol use days. Generalized linear mixed effects models were used to predict drinking level (moderate: 1-3/1-4 for women/men; heavy-episodic drinking (HED): 4-7/5-9; high-intensity drinking (HID), 8+/10+) by social (e.g., with friends) and physical (e.g., at a party) contexts. We conducted analyses for the first and last drink reported, controlling demographic and study characteristics. RESULTS Being at a party, friend's house, or with strangers at the last drink reported were associated with HID compared to HED, while being at home, alone, or with family were protective for HID. No first drink contexts were associated with HID relative to HED. Witnessing others who were intoxicated was consistently associated with HID. CONCLUSIONS Social settings such as parties and those with intoxicated persons were associated with risk for HID. The context of drinks at the end of an event are salient signals of level of alcohol consumption. Preventive interventions, particularly those that deliver strategies in real time, should consider accounting for contextual risk factors to reduce harms associated with excessive alcohol consumption.

The impact of changes in COVID-19 lockdown restrictions on alcohol consumption and drinking occasion characteristics in Scotland and England in 2020: an interrupted time-series analysis. Addiction 2022; 117:1622-1639. [PMID: 35108758 PMCID: PMC9302640 DOI: 10.1111/add.15794] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 12/13/2021] [Indexed: 01/25/2023]
Abstract
BACKGROUND AND AIMS Early evidence suggests that COVID-19 lockdown restrictions affect alcohol consumption. However, existing studies lack data on how drinking practices changed as restrictions disrupted people's work, family life and socializing routines. We examined changes in consumption and drinking occasion characteristics during three periods of changing restrictions in Scotland/England. DESIGN Interrupted time-series analysis of repeat cross-sectional market research data (assessing step-level changes). SETTING Scotland/England, January 2009-December 2020. PARTICIPANTS Scotland: 41 507 adult drinkers; England: 253 148 adult drinkers. MEASUREMENTS Three intervention points: March 2020 lockdown, July 2020 easing of restrictions and October 2020 re-introduction of some restrictions. PRIMARY OUTCOME mean units consumed per week (total/off-trade/on-trade; 1 unit = 8 g ethanol). SECONDARY OUTCOMES drinking > 14 units per week, heavy drinking, drinking days per week, solitary drinking, drinking with family/partners, drinking with friends/colleagues, own-home drinking, drinking in someone else's home and drinking start times. FINDINGS In Scotland, March 2020's lockdown was associated with a 2.32 [95% confidence interval (CI) = 0.61, 4.02] increase in off-trade (i.e. shop-bought) units per week, a -2.84 (95% CI = -3.63, -2.06) decrease in on-trade (i.e. licensed venues) units per week, but no statistically significant change in total units per week. July 2020's easing of restrictions was associated with a 1.33 (95% CI = 0.05, 2.62) increase in on-trade units per week, but no statistically significant total/off-trade consumption changes. October 2020's re-introduction of some restrictions was not associated with statistically significant consumption changes. Results for England were broadly similar. Lockdown restrictions were also associated with later drinking start times, fewer occasions in someone else's home and with friends/colleagues, more own-home drinking and (in Scotland only) more solitary drinking. CONCLUSIONS Reductions in on-trade alcohol consumption following COVID-19 lockdown restrictions in Scotland/England in 2020 were mainly offset by increased own-home drinking. This largely persisted in periods of greater/lesser restrictions. The shift towards off-trade drinking involved significant changes in the characteristics of drinking occasions.

Abstract
This paper compares drinking patterns of Whites and Hispanics who after crossing the U.S./Mexico border drink and do not drink in Mexico. Data came from a household survey of 1,209 adults 18 to 39 years of age in California. Residence near the US/Mexico border increases the likelihood of drinking in Mexico (AOR = 4.57; 95%CI = 2.45-8.52; p < .001). Hispanics (AOR = 1.91; 95%CI = 1.26-2.90; p < .01), those who drink more frequently (AOR = 1.05; 95%CI = 1.02-1.09; p < .01) and those who drink six or more drinks in day (AOR = 1.91; 95%CI = 1.26-2.29; p < .01) are more likely than Whites and lighter drinkers to report this behavior. Crossing the U.S./Mexico border to drink is influenced by living close to the border, Hispanic ethnicity, and drinking many drinks in a day.

Boyd J, Bambra C, Purshouse RC, Holmes J. Beyond Behaviour: How Health Inequality Theory Can Enhance Our Understanding of the 'Alcohol-Harm Paradox'. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:6025. [PMID: 34205125 PMCID: PMC8199939 DOI: 10.3390/ijerph18116025] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 05/24/2021] [Accepted: 06/02/2021] [Indexed: 11/16/2022]
Abstract
There are large socioeconomic inequalities in alcohol-related harm. The alcohol harm paradox (AHP) is the consistent finding that lower socioeconomic groups consume the same or less as higher socioeconomic groups yet experience greater rates of harm. To date, alcohol researchers have predominantly taken an individualised behavioural approach to understand the AHP. This paper calls for a new approach which draws on theories of health inequality, specifically the social determinants of health, fundamental cause theory, political economy of health and eco-social models. These theories consist of several interwoven causal mechanisms, including genetic inheritance, the role of social networks, the unequal availability of wealth and other resources, the psychosocial experience of lower socioeconomic position, and the accumulation of these experiences over time. To date, research exploring the causes of the AHP has often lacked clear theoretical underpinning. Drawing on these theoretical approaches in alcohol research would not only address this gap but would also result in a structured effort to identify the causes of the AHP. Given the present lack of clear evidence in favour of any specific theory, it is difficult to conclude whether one theory should take primacy in future research efforts. However, drawing on any of these theories would shift how we think about the causes of the paradox, from health behaviour in isolation to the wider context of complex interacting mechanisms between individuals and their environment. Meanwhile, computer simulations have the potential to test the competing theoretical perspectives, both in the abstract and empirically via synthesis of the disparate existing evidence base. Overall, making greater use of existing theoretical frameworks in alcohol epidemiology would offer novel insights into the AHP and generate knowledge of how to intervene to mitigate inequalities in alcohol-related harm.

Alcohol Clin Exp Res 2021; 45:630-637.

Abstract
BACKGROUND Alcohol consumption is influenced by the characteristics of drinking occasions, for example, location, timing, or the composition of the drinking group. However, the relative importance of occasion characteristics is not yet well understood. This study aims to identify which characteristics, and combinations of characteristics, are associated with units consumed within drinking occasions. It also tests whether accounting for occasion characteristics improves the prediction of consumption compared to using demographic information only. METHODS The data come from a cross-sectional, nationally representative, online market research survey. Our sample includes 18,409 British drinkers aged 18 + who recorded the characteristics of 46,072 drinking occasions using 7-day retrospective drinking diaries in 2018. We used decision tree modeling and nested linear regression to predict units consumed in occasions using information on drinking location/venue, occasion timing, company, occasion type (e.g., a quiet night in), occasion motivation, drink type and packaging, food eaten and entertainment/ other activities during the occasion. We estimated models separately for 6 age-sex groups and controlled for usual drinking frequency, and social grade in nested linear regression models. Open Science Framework preregistration: https://osf.io/42epd. RESULTS Our 6 final models accounted for between 55% and 71% of the variance in drinking occasion alcohol consumption. Beyond demographic characteristics (1 to 9%) and occasion duration (24 to 60%), further occasion characteristics and combinations of characteristics accounted for 31 to 70% of the total explained variance. The characteristics most strongly associated with heavy alcohol consumption were long occasion duration, drinking spirits as doubles, and drinking wine. Spirits were also consumed in light occasions, but as singles. This suggests that the serving size is an important differentiator of light and heavy occasions. CONCLUSIONS Combinations of occasion duration and drink type are strongly predictive of alcohol consumption in adults' drinking occasions. Accounting for characteristics of drinking occasions, both individually and in combination, substantially improves the prediction of alcohol consumption.

Abstract
Young adults are at high risk for sexual harassment and sexual assault. Although attention has been given to prevention on college campuses, the need for prevention may be at least as high for young adults who do not attend college as for young adults who do. In October 2019, we administered a nationally representative survey of 893 adults to measure sexual harassment and sexual assault victimization during a recall period defined as "during college years" for respondents who had enrolled in college at any time or "ages 18-24" for respondents not in college. Reported rates of sexual harassment (32.7%) and sexual assault (24.6%) during early adulthood were similar for respondents who reported having ever enrolled in college and for respondents who reported never attending college. Women were more likely than men to report both sexual harassment (37.4% vs 22.4%) and sexual assault (36.0% vs 16.0%) during early adulthood. Compared with respondents aged ≥30, respondents aged 18-29 were 105% more likely to report sexual harassment and 65% more likely to report sexual assault. Moreover, sexual harassment experiences predicted sexual assault victimization (adjusted odds ratio = 18.1). This study highlights the importance of attending to sexual harassment and sexual assault risks for young adults through research, policy, and criminal justice structures beyond institutions of higher education. Evidence that sexual harassment is strongly associated with sexual assault victimization of young adults highlights the importance of naming and stemming early behavioral transgressions across the US population.
