Association of Cannabis Use and At-Risk Alcohol Use With Intimate Partner Violence in an Urban ED Sample.

INTRODUCTION: Urban ED patients have elevated rates of substance use and intimate partner violence. The purpose of this study is to describe the risk profiles for intimate partner violence among urban ED patients who report at-risk alcohol use only, cannabis use only, or both types of substance use. METHODS: Cross-sectional survey data were collected from study participants (N = 1037; 53% female; ages 18-50) following informed consent. We measured participants' past-year at-risk drinking (women/men who had 4+/5+ drinks in a day), cannabis use, psychosocial and demographic characteristics, and past-year physical intimate partner violence (assessed with the Revised Conflict Tactics Scale). We used bivariate analysis to assess whether rates of intimate partner violence perpetration and victimization differed by type of substance use behavior. Multivariate logistic regression models were estimated for each intimate partner violence outcome. All analyses were stratified by gender. RESULTS: Rates of intimate partner violence differed significantly by type of substance use behavior and were highest among those who reported both at-risk drinking and cannabis use. Multivariate analysis showed that women who reported at-risk drinking only, cannabis use only, or both types of substance use had increased odds for intimate partner violence perpetration and victimization compared with women who reported neither type of substance use. Men's at-risk drinking and cannabis use were not associated with elevated odds of intimate partner violence perpetration or victimization. DISCUSSION: Brief screening of patients' at-risk drinking and cannabis use behaviors may help identify those at greater risk for intimate partner violence and those in need of referral to treatment.

Adverse childhood experiences are associated with at-risk drinking, cannabis and illicit drug use in females but not males: an Emergency Department study.

BACKGROUND: Adverse childhood experiences (ACEs) are associated with adult substance use in the general population. Given pervasive health disparities among underserved populations, understanding how ACEs are associated with substance use among urban Emergency Department (ED) patients could help inform design of effective screening, brief interventions, and referral to treatment. OBJECTIVES: To estimate gender differences in prevalence of separate and cumulative ACEs among a sample of urban ED patients, and assess its association with at-risk drinking (4+/5+ drinks for females/males), cannabis, and illicit drug use. We hypothesized that the association between ACEs and each outcome would be stronger among females than males. METHODS: Cross-sectional survey data were obtained from 1,037 married/partnered ED patients (53% female) at a public safety-net hospital. Gender-stratified logistic regression models were estimated for each substance use outcome. RESULTS: One+ ACEs were reported by 53% of males and 60% of females. Females whose mother was a victim of domestic violence had greater odds of at-risk drinking compared to females who did not report this ACE (AOR = 1.72; 95% CI 1.03, 2.88). Females' cumulative ACEs were associated with cannabis use (OR = 2.26, 95% CI 1.06, 4.83) and illicit drug use (OR = 3.35; 95% CI 1.21, 9.30). Males' separate and cumulative ACEs were not associated with increased likelihood for any of the outcomes. CONCLUSION: ACEs are associated with greater odds of substance use among female than male ED patients. The prevalence of ACE exposure in this urban ED sample underscores the importance of ED staff providing trauma-informed care.

Alcohol outlet density and intimate partner violence-related emergency department visits.

BACKGROUND: Previous research has identified risk factors for intimate partner violence (IPV) severity, injury, and emergency department (ED) visits. These risk factors have been shown at both the individual level (heavy drinking and other substance use on the part of 1 or both partners) and the neighborhood level (residence in an area characterized by poverty and social disadvantage). Alcohol outlet density has been linked with assaultive violence in community settings, but has not been analyzed in relation to IPV-related ED visits. This study examined the effects of outlet densities on IPV-related ED visits throughout California between July 2005 and December 2008. METHODS: Half-yearly counts of ED visits related to IPV (E-code 967.3) were computed for each zip code from patient-level public data sets. Alcohol outlet density measures, calculated separately for bars, off-premise outlets, and restaurants, were derived from California Alcohol Beverage Control records. Census-based neighborhood demographic characteristics previously shown to be related to health disparities and IPV (percent black, percent Hispanic, percentage below 150% of poverty line, percent unemployed) were included in models. This study used Bayesian space-time models that allow longitudinal analysis at the zip code level despite frequent boundary redefinitions. These spatial misalignment models control for spatial variation in geographic unit definitions over time and account for spatial autocorrelation using conditional autoregressive (CAR) priors. The model incorporated data from between 1,686 (2005) and 1,693 (2008) zip codes across California for 7 half-year time periods from 2005 through 2008 (n = 11,836). RESULTS: Density of bars was positively associated with IPV-related ED visits. Density of off-premise outlets was negatively associated with IPV-related ED visits; this association was weaker and smaller than the bar association. There was no association between density of restaurants and IPV-related ED visits. CONCLUSIONS: Further research is needed to understand the mechanisms by which environmental factors, such as alcohol outlet density, affect IPV behaviors resulting in ED visits.

Food Service Employee Alcohol Use, Hangovers and Norms During and After Work Hours.

AIMS: This paper presents analyses of norms and behavior concerning drinking before, during, and after work hours among U.S. bar-restaurant chain employees, with a focus on hangovers at work and their correlates. METHODS: A mixed method approach combined qualitative analysis of 64 face-to-face interviews held with randomly chosen service, managerial and kitchen staff and quantitative analyses (including multivariable linear regression and bivariate analyses) of data drawn from 1,286 completed telephone surveys (response rate 68%) with 18-29 year old employees. RESULTS: Relatively few survey respondents reported past-year drinking in the hour prior to work (5%) or during work hours (2.7%), but extensive drinking in non- work hours (85.5%), and 36.5% of respondents reported coming to work with a hangover at least once. Correlates of hangover at work were past year intoxication and holding positive norms for hangovers. These findings were elaborated by interview data describing heavy drinking after work at nearby bars, restaurants and employee homes. CONCLUSIONS: The findings illustrated that employee drinking during work hours was not normative. However, study results portrayed widely-shared norms for heavy drinking outside of work, with hangovers and related harms appearing as the primary work time repercussions of after-work alcohol consumption.

Alcohol outlets, neighborhood characteristics, and intimate partner violence: ecological analysis of a California city.

Neighborhood indicators of social disadvantage, such as poverty and unemployment, are associated with intimate partner violence (IPV). Despite the well-established link between heavy drinking and IPV, few studies have analyzed the contribution of alcohol outlet density to the occurrence of IPV. Greater numbers of alcohol outlets in a community may be a sign of loosened normative constraints against violence, promote problem drinking among at-risk couples, and provide environments where groups of persons at risk for IPV may form and mutually reinforce IPV-related attitudes, norms, and problem behaviors. This study used ecological data to determine if alcohol outlet density (number of bars, restaurants serving alcohol, and off-premise outlets per unit area) is related to rates of IPV-related police calls and IPV-related crime reports in Sacramento, California. Separate analyses for IPV calls and crime reports were conducted using Bayesian space-time models adjusted for area characteristics (poverty rate, unemployment rate, racial/ethnic composition). The results showed that each additional off-premise alcohol outlet is associated with an approximate 4% increase in IPV-related police calls and an approximate 3% increase in IPV-related crime reports. Bars and restaurants were not associated with either outcome. The findings suggest that alcohol outlet density, especially off-premise outlets, appear to be related to IPV events. Further research is needed to understand the mechanisms by which neighborhood factors, such as alcohol outlet density, affect IPV behaviors. Understanding these mechanisms is of public health importance for developing environmental IPV prevention strategies, such as changes in zoning, community action, education, and enforcement activities.

Measuring intimate partner violence among male and female farmworkers in San Diego County, CA.

Although there are over one million farmworkers in the United States, little is known about intimate partner violence (IPV) among this population. Given the particular demands of agricultural labor, however, farmworkers and their partners are highly susceptible to a host of occupation-specific stressors that may result in relationship conflict, and thereafter IPV. In cases where one or both members of the dyad engage in problematic drinking, the likelihood of violence increases exponentially. The purpose of this exploratory quantitative study was to estimate the prevalence of IPV among a mixed gender sample of farmworkers in San Diego County, California, and assess the association of potential correlates (acculturation- and work-related stress, problem drinking, and impulsivity) to IPV. Bilingual interviewers conducted survey data collection by using standardized instruments (e.g., Revised Conflict Tactics Scale; Migrant Farm Work Stress Inventory; AUDIT). Nearly all participants (n = 100) were Mexican born. Results showed that approximately 16% of female individuals (n = 61) and 32% of male individuals (n = 37) reported partner violence perpetration, victimization, or both, in the past year. Significant correlates of IPV were problem drinking (among males) and impulsivity (among females). This study demonstrates the feasibility of conducting IPV research among male and female farmworkers. Additional research is warranted to more fully explore the role of acculturation- and work-related stress, drinking, and other personal characteristics and environmental factors in precipitating couple conflict and thereafter IPV.

The relationship of alcohol problems to the risk for unidirectional and bidirectional intimate partner violence among a sample of blue-collar couples.

Understanding how each partner's alcohol problems may contribute to the risk of male-to-female only, female-to-male only, or bidirectional partner violence is important for the prevention and treatment of these problems. Multinomial regression analysis was conducted using data from 848 blue-collar couples. Findings suggest that male alcohol problems are linked to male-to-female and bidirectional partner violence but not with female-to-male partner violence. Female alcohol problems do not appear to be related to any type of partner aggression. Each partner's level of impulsivity was associated with bidirectional partner violence. Male impulsivity was associated with male-to-female violence, and female impulsivity was associated with female-to-male violence. Prevention of male alcohol problems and promotion of nonconfrontational conflict-solving techniques may help reduce partner aggression among couples in the general household population.

Interrelationships of Economic Stressors, Mental Health Problems, Substance Use, and Intimate Partner Violence among Hispanic Emergency Department Patients: The Role of Language-Based Acculturation.

We analyzed the interrelationships of economic stressors, mental health problems, substance use, and intimate partner violence (IPV) among a sample of Hispanic emergency department patients and probed if Spanish language preference, which may represent low acculturation and/or immigrant status, had a protective effect, in accordance with the Hispanic health paradox. Study participants (n = 520; 50% female; 71% Spanish speakers) provided cross-sectional survey data. Gender-stratified logistic regression models were estimated for mental health problems (PTSD, anxiety, depression), substance use (risky drinking, cannabis, illicit drug use), and IPV. Results showed that economic stressors were linked with mental health problems among men and women. Among men, PTSD was associated with greater odds of cannabis and illicit drug use. Men who used cannabis and illicit drugs were more likely to report IPV. Male Spanish speakers had lower odds of anxiety and cannabis use than English speakers. Female Spanish speakers had lower odds of substance use and IPV than English speakers. The protective effect of Spanish language preference on some mental health, substance use, and IPV outcomes was more pronounced among women. Future research should identify the mechanisms that underlie the protective effect of Spanish language preference and explore factors that contribute to the observed gender differences.

Racial/Ethnic Discrimination and Intimate Partner Violence Perpetration in Latino Men: The Mediating Effects of Mental Health.

PURPOSE: Intimate partner violence (IPV) is a serious public health problem that disproportionately affects racial/ethnic minorities in the U.S. This study examines risk factors for IPV perpetration that are salient for racial/ethnic minorities; specifically, we test if racial/ethnic discrimination among Latino men is associated with IPV perpetration, if poor mental health (MH) mediates this link, and whether relationships differ by immigrant status. METHODS: Using National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-II) Wave 2 (2004-2005) data, multigroup structural equation modeling compared immigrant (N = 1187) and U.S.-born (N = 1077) Latinos on a mediation model whereby discrimination increases IPV risk via poor MH (anxiety, depression, post-traumatic stress (PTSS); alcohol dependence (AD) and drug dependence (DD)). RESULTS: For U.S.-born Latinos, discrimination increased anxiety (ß = 0.24, p < 0.001), depression (ß = 0.16, p < 0.001), PTSS (ß = 0.09, p < 0.001), AD (ß = 0.11, p < 0.001) and DD (ß = 0.16, p < 0.001); anxiety (ß = 0.16, p < 0.001), AD (ß = 0.19, p < 0.001) and DD (ß = 0.09, p < 0.01) increased IPV risk. Among Latino immigrants, discrimination increased anxiety (ß = 0.07, p < 0.001), depression (ß = 0.16, p < 0.001), PTSS (ß = 0.08, p < 0.001) and DD (ß = 0.03, p < 0.001); PTSS (ß = 0.16, p < 0.001), AD (ß = 0.21, p < 0.001) and DD (ß = 0.05, p < 0.01) increased IPV risk. CONCLUSIONS: Among Latino men, discrimination is associated with poorer MH and contributes to IPV perpetration; MH risk factors vary by immigrant status.

Co-Occurrence of Multiple Risk Factors and Intimate Partner Violence in an Urban Emergency Department.

INTRODUCTION: Urban emergency departments (ED) provide care to populations with multiple health-related and overlapping risk factors, many of which are associated with intimate partner violence (IPV). We examine the 12-month rate of physical IPV and its association with multiple joint risk factors in an urban ED. METHODS: Research assistants surveyed patients regarding IPV exposure, associated risk factors, and other sociodemographic features. The joint occurrence of seven risk factors was measured by a variable scored 0-7 with the following risk factors: depression; adverse childhood experiences; drug use; impulsivity; post-traumatic stress disorder; at-risk drinking; and partner's score on the Alcohol Use Disorders Identification Test. The survey (N = 1037) achieved an 87.5% participation rate. RESULTS: About 23% of the sample reported an IPV event in the prior 12 months. Logistic regression showed that IPV risk increased in a stepwise fashion with the number of present risk factors, as follows: one risk factor (adjusted odds ratio [AOR] [3.09]; 95% confidence interval [CI], 1.47-6.50; p<.01); two risk factors (AOR [6.26]; 95% CI, 3.04-12.87; p<.01); three risk factors (AOR = 9.44; 95% CI, 4.44-20.08; p<.001); four to seven risk factors (AOR [18.62]; 95% CI, 9.00-38.52; p<001). Ordered logistic regression showed that IPV severity increased in a similar way, as follows: one risk factor (AOR [3.17]; 95% CI, 1.39-7.20; p<.01); two risk factors (AOR [6.73]; 95% CI, 3.04-14.90; p<.001); three risk factors (AOR [10.36]; 95%CI, 4.52-23.76; p<.001); four to seven risk factors (AOR [20.61]; 95% CI, 9.11-46.64; p<001). CONCLUSION: Among patients in an urban ED, IPV likelihood and IPV severity increase with the number of reported risk factors. The best approach to identify IPV and avoid false negatives is, therefore, multi-risk assessment.

Problem Drinking and Marijuana Use as Risks for Unidirectional and Bidirectional Partner Violence.

Despite evidence that most who perpetrate intimate partner violence (IPV) also report victimization, little is known about bidirectional IPV among Emergency Department (ED) patients and its association with problem drinking and marijuana use. We conducted an observational, cross-sectional survey among low- and moderate-acuity patients at a Northern California safety-net ED. Physical IPV was measured with the Revised Conflict Tactics Scale (CTS2). We recorded patient's frequency of intoxication and marijuana use. Spouse/partner's problem drinking and marijuana use were measured dichotomously. Odds Ratios [ORs] and 95% confidence intervals [CIs] were estimated using multinomial logistic regression models of unidirectional and bidirectional IPV. Among 1,037 patients (53% female), perpetration only, victimization only, and bidirectional IPV were reported by 3.8%, 6.2%, and 13.3% of the sample, respectively. Frequency of intoxication was associated with perpetration (OR 1.50; 95% CI 1.18 to 1.92) and bidirectional IPV (OR=1.34; 95% CI 1.13 to 1.58). Days of marijuana use were associated with bidirectional IPV (OR=1.15; 95% CI 1.03 to 1.28). Patients whose partners were problem drinkers were at risk for victimization (OR=2.56; 95% CI=1.38, 4.76) and bidirectional IPV (OR=1.97; 95% CI 1.18, 3.27). Among patients who reported any past-year IPV, most experienced bidirectional aggression. ED staff should consider asking patients who are married, cohabiting, or in a dating relationship about their experience with past-year IPV and inquire about their substance use patterns and those of their romantic partner, to share information about potential linkages. Medical and recreational marijuana legalization trends underscore the importance of further research on IPV and marijuana.

Frequency of Intimate Partner Violence among an Urban Emergency Department Sample: A Multilevel Analysis.

Intimate partner violence (IPV) is a pervasive public health problem. Within the U.S., urban emergency department (ED) patients have elevated prevalence of IPV, substance use, and other social problems compared to those in the general household population. Using a social-ecological framework, this cross-sectional study analyzes the extent to which individual, household, and neighborhood factors are associated with the frequency of IPV among a socially disadvantaged sample of urban ED patients. Confidential survey interviews were conducted with 1037 married/partnered study participants (46% male; 50% Hispanic; 29% African American) at a public safety-net hospital. Gender-stratified multilevel Tobit regression models were estimated for frequency of past-year physical IPV (perpetration and victimization) and frequency of severe IPV. Approximately 23% of participants reported IPV. Among men and women, impulsivity, adverse childhood experiences, substance use, and their spouse/partner's hazardous drinking were associated with IPV frequency. Additionally, household food insufficiency, being fired or laid off from their job, perceived neighborhood disorder, and neighborhood demographic characteristics were associated with IPV frequency among women. Similar patterns were observed in models of severe IPV frequency. IPV prevention strategies implemented in urban ED settings should address the individual, household, and neighborhood risk factors that are linked with partner aggression among socially disadvantaged couples.

Drinking Context-Specific Dose-Response Models of Intimate Partner Violence Among an Urban Emergency Department Sample.

OBJECTIVE: This cross-sectional study evaluates the association between physical intimate partner violence (IPV) and frequencies of drinking and volume consumed in six different contexts among a sample of urban emergency department (ED) patients. METHOD: We obtained survey data from 1,037 married, cohabiting, or partnered patients (53% female; 50% Hispanic; 29% African American) at a Northern California safety-net hospital. Past-year physical IPV was measured with the Revised Conflict Tactics Scale. We asked patients about frequency of drinking and usual number of drinks consumed at bars, restaurants, homes of friends or relatives, own home, public places such as street corners or parking lots, and community centers or large events. Gender-stratified dose-response models were estimated for frequencies of IPV perpetration and victimization, with adjustment for sociodemographic and psychosocial factors, marijuana use, and spouse/partner problem drinking. RESULTS: None of the women's context-based frequency and volume measures were associated with frequency of IPV victimization. Women's volume of alcohol consumed at home was associated positively with frequency of their IPV perpetration (ß = .008, SE = .003, p < .01), and volume consumed in public places was associated negatively with this outcome (ß = -.023, SE = .010, p < .05). Among men, none of the context-based frequency and volume measures were associated with frequency of either IPV outcome. Spouse/partner's problem drinking was associated with each gender's IPV victimization, and with IPV perpetration by men. CONCLUSIONS: Frequency of drinking and volume consumed in specific contexts do not substantively contribute to frequency of IPV perpetration or victimization in this sample of urban ED patients.

Association of occupational and substance use factors with burnout among urban transit operators.

Burnout is a special type of prolonged occupational stress that is linked with numerous psychosomatic and psychological sequelae and negative job consequences. The purpose of this study is to estimate the contribution of occupational and substance use factors to burnout among a multiethnic sample of urban transit operators (n = 1231). Survey and medical exam data were obtained from participants in the 1993-1995 San Francisco MUNI Health & Safety Study. Burnout was measured with the Maslach Burnout Inventory emotional exhaustion subscale. Occupational factors included frequency of job problems (e.g., equipment, passengers, and traffic), years driving, full or part-time work status, and ergonomic problems (e.g., adjusting the seat, back support, vibration, and rocking or bouncing of seat). Substance use measures were alcohol consumption and smoking status (i.e., current, former, and never smokers). The results of multivariable linear regression analysis showed that job problems (beta = 0.426, p < 0.001), ergonomic problems (beta = 0.138, p < 0.001), and full-time work status (beta = 0.070, p < 0.01) were associated with burnout. Smoking was not significant, but alcohol consumption was positively associated with burnout (beta = 0.067, p < 0.01). Age was negatively correlated with burnout (beta = -0.106, p < 0.001), which may reflect a healthy worker effect. Because aspects of the psychosocial and physical work environments can be modified, the findings have important implications for the prevention of burnout among municipal transit operators.

Dimensions of problem drinking among young adult restaurant workers.

BACKGROUND: Nationwide surveys identify food service workers as heavy alcohol users. OBJECTIVES: This article analyzes dimensions and correlates of problem drinking among young adult food service workers. METHODS: A telephone survey of national restaurant chain employees yielded 1,294 completed surveys. RESULTS: Hazardous alcohol consumption patterns were seen in 80% of men and 64% of women. Multivariate analysis showed that different dimensions of problem drinking measured by the AUDIT were associated with workers' demographic characteristics, smoking behaviour, and job category. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: These findings offer evidence of extremely high rates of alcohol misuse among young adult restaurant workers.

Agreement on intimate partner violence among a sample of blue-collar couples.

This study assessed agreement level about the occurrence of past-year male-to-female partner violence (MFPV) and female-to-male partner violence (FMPV) among a sample of 897 blue-collar couples. Intimate partner violence (IPV) was measured with the Physical Assault subscale of the revised Conflict Tactics Scales (CTS2). Agreement level was assessed with Cohen's kappa statistic. Lower-bound estimates (based on couple agreement that an IPV event occurred) and upper-bound estimates (based on uncorroborated reports from either partner that an IPV event occurred) were calculated. Results indicated low agreement for most IPV behaviors (kappa < .40). Estimated lower- and upper-bound rates for MFPV were 6.7% and 21.2%, for FMPV, 7.1% and 24.2%, and for any IPV, 10.1% and 30.2%. Findings suggest that single-point IPV prevalence estimates are biased; lower- and upper-bound estimates using collateral reports should be calculated when possible. In addition, findings underscore the importance of conducting IPV research among understudied populations, such as working-class couples, that may be at elevated IPV risk.

Intimate partner violence among hispanic men and women: the role of drinking, neighborhood disorder, and acculturation-related factors.

Using secondary data analysis, this study assessed the contribution of drinking, neighborhood disorder, and acculturation-related factors to past-year intimate partner violence (IPV) risk among a national sample of married or cohabiting Hispanic men (n = 1,148) and women (n = 1,399) who participated in the 2000 National Household Survey on Drug Abuse. Drinking measures were past-year alcohol abuse, past-month binge drinking, and number of past-year drinking days. Neighborhood disorder was measured by perceived level of neighborhood problems. Acculturation-related factors were nativity and survey interview language preference (Spanish vs. English). Similar proportions of men and women reported IPV perpetration (6.1% vs. 6.5%) and IPV victimization (8.8% vs. 7.8%). Logistic regression results indicated that for men, neighborhood disorder was associated with IPV perpetration (odds ratio [OR] = 1.55) and victimization (OR = 1.36). For women, neighborhood disorder (OR = 1.34) and their alcohol abuse (OR = 10.26) were associated with IPV victimization, but not IPV perpetration. Acculturation-related factors were not associated with IPV perpetration or victimization for men or women. The findings suggest that IPV prevention efforts should address deleterious neighborhood conditions in addition to individual-level factors that place couples at risk for IPV.

Gender Differences in Smoking Among an Urban Emergency Department Sample.

BACKGROUND: Urban emergency department (ED) patients have elevated smoking and substance use compared with the general population. We analyzed gender differences in smoking among an urban ED sample and assessed the contribution of substance use, demographic, and couple factors. METHODS: We conducted a secondary analysis of data obtained from a cross-sectional, observational survey (N = 1037 participants) on drinking, drug use, and intimate partner violence (IPV). Gender-specific logistic regression models for current (past 30-day) smoking and multinomial regression models for smoking intensity (light: ⩽5 cigarettes per day [CPD]; moderate: 6 to 10 CPD; heavier: >10 CPD) were estimated. RESULTS: Smoking prevalence was higher among men than women (35.5% vs 18.9%; P < .001). Substance use (frequency of intoxication, marijuana, amphetamine, and cocaine use), demographic (food insufficiency, unemployment), and couple-related factors (having a spouse/partner who smoked, IPV involvement, being in a same-gender couple) were differentially associated with current smoking and level of intensity among men and women. CONCLUSIONS: Emergency department staff should consider the impact of polysubstance use, food insufficiency, unemployment, and whether both partners in the couple smoke when screening patients for smoking and formulating cessation treatment plans. Women in same-gender relationships and those who have experienced IPV involvement may require additional referral.

Drinking and Intimate Partner Violence Severity Levels Among U.S. Ethnic Groups in an Urban Emergency Department.

BACKGROUND: Emergency departments (EDs) provide care to ethnically diverse populations with multiple health-related risk factors, many of which are associated with intimate partner violence (IPV). This paper examines ethnic-specific 12-month rates of physical IPV by severity and their association with drinking and other sociodemographic and personality correlates in an urban ED sample. METHODS: Research assistants surveyed patients at an urban ED regarding IPV exposure as well as patterns of alcohol and drug use, psychological distress, adverse childhood experiences (ACEs), and other sociodemographic features. RESULTS: The survey (N = 1,037) achieved an 87.5% participation rate. About 23% of the sample reported an IPV event in the past 12 months. Rates were higher (p < 0.001) among blacks (34%), whites (31%), and multiethnic (46%) respondents than those among Asians (13%) and Hispanics (15%). Modeled results showed that black respondents were more likely than Hispanics (reference) to report IPV (adjusted odds ratio [AOR] = 1.69, 95% confidence interval [CI] = 1.98-2.66, p < 0.05) and that respondents' partner drinking was associated with IPV (AOR = 1.85, 95% CI = 1.25-2.73, p < 0.01) but respondents' drinking was not. Use of illicit drugs, younger age, impulsivity, depression, partner problem drinking, ACEs, and food insufficiency were all positively associated with IPV. CONCLUSIONS: There was considerable variation in IPV rates across ethnic groups in the sample. The null results for the association between respondents' drinking and IPV was surprising and may stem from the relatively moderate levels of drinking in the sample. Results for ethnicity, showing blacks as more likely than Hispanics to report IPV, support prior literature.

Prevalence and Correlates of Current and Former Smoking among Urban Transit Workers.

Transit workers constitute a blue-collar occupational group that have elevated smoking rates relative to other sectors of employed adults in the United States. This study analyzed cross-sectional tobacco survey data from 935 workers (60% African American; 37% female) employed at an urban public transit agency in California. Prevalence of current and former smoking was 20.3% and 20.6%, respectively. Younger workers were less likely than older workers to be current or former smokers. Having a complete home smoking ban was associated with decreased likelihood of being a smoker [odds ratio (OR) = 0.04, 95% confidence interval (CI) = 0.01-0.17], as were neutral views about whether it is easy for a smoker to take a smoking break during their shift (OR = 0.50, 95% CI 0.28-0.88). Current smoking among the sample is > 50% higher than the adult statewide prevalence. Potential points of intervention identified in this study include perceived ease of worksite smoking breaks and establishing home smoking bans. Tailored cessation efforts focusing on older transit workers more likely to smoke are needed to reduce tobacco-related disparities in this workforce.
