Drinking context and intimate partner violence: evidence from the California community health study of couples

Proximity to Alcohol Sellers and Dose Response Relationship Between Alcohol Consumption With Intimate Partner Violence in Rural Southwestern Uganda

Introduction: Intimate partner violence (IPV) is associated with several adverse public health outcomes and alcohol use is one of its risk factors. Proximity to alcohol selling points could be linked with problem drinking and IPV. We aimed to determine whether proximal location to alcohol and intensity of alcohol consumption are associated with IPV in rural southwest Uganda.Methods: We conducted a cross-sectional study in rural southwest Uganda with structured interviews at household level. We used the alcohol use disorders identification test (AUDIT) and the Conflict Tactics Scale to measure past year alcohol consumption and IPV (perpetration and victimization). We estimated Euclidean distances between participants' households and nearest alcohol outlets using geographic information systems. We used generalized estimating equation models to calculate adjusted odds ratios (aOR) for the factors associated with IPV.Results: We enrolled 742 participants and median age was 41 years (inter-quartile range or IQR 32-53) and 52.2% of respondents were male. The overall prevalence of IPV in the past year was 52.2%. In a multivariable regression model, women (aOR = 2.24, 95%CI 1.28, 3.91) compared to men, those living proximal to an alcohol selling point (OR = 1.77, 95% CI 1.38, 2.27) were more likely to experience IPV. There was a dose-response relationship between alcohol consumption and IPV. With non-drinkers as the reference category, the aORs were 4.54 (95% CI 2.04, 10.08) for casual drinkers, 10.53 (95% CI 4.15, 26.77) for hazardous drinkers and 15.31 (95% CI 4.73, 49.54) for alcohol dependent drinkers.Conclusion: IPV is very common and has a dose-response relationship with alcohol consumption and drinking outlet proximity. There is an urgent need for IPV and alcohol interventions programs in these rural communities. Policy to restrict proximity of alcohol outlets to residential locations should be examined as an intervention for alcohol consumption and IPV perpetration.

Can Emerging Adults' Dating Psychological Aggression be Explained by Family-of-Origin Psychological Aggression, Emotion Dysregulation, and Drinking?

Intimate partner violence (IPV) impacts the lives of millions of individuals; nearly 1 in 4 women and 1 in 7 men report experiencing IPV during their lifetime. Previous studies frequently cite family-of-origin aggression as a risk factor for later experiences with IPV. Research with adults who engage in IPV finds an association with childhood exposure to family violence, but the strength of that association may vary. Psychological aggression often pre-dates more severe IPV and college students are a particular risk group for IPV. Additionally, previous literature has revealed gender differences in response to childhood experiences of family violence. As such, the current study sought to identify factors that explain and moderate risk for dating psychological aggression (DPA) in college adults, and sex differences in those associations. Participants (464 women, 142 men), who were in a current romantic relationship lasting at least 3 months, completed measures of past psychological aggression in the family-of-origin (PAF), current emotion dysregulation, risky drinking, and DPA perpetrated in current dating relationships. Emotion dysregulation mediated the relationship between PAF and current DPA; however, differences among specific types of PAF and sex were noted. Results support an intergenerational transmission of PAF and suggest that parent-child sex dyads influence this process. The findings also provide evidence that higher levels of drinking are associated with increased emotion dysregulation. These results contrast with the alcohol expectancy for stress relief and support public messaging that alcohol use does not relieve stress. Clinical and research implications for prevention of the intergenerational transmission of aggression are discussed.

Alcohol Use Frequencies and Associated Problems Across Drinking Contexts

OBJECTIVE

To better quantify the impact of specific on- and off-premise drinking contexts on population-level alcohol-related problems, we evaluated context-specific risks relative to frequency of use of each context.

METHOD

We surveyed 860 adult (21-100 years) past-year drinkers in the California East Bay, sampled in areas of high versus low median household income and off-premise alcohol outlet densities. We examined associations of context-specific drinking frequencies in seven on- and off-premise drinking locations with individual and area characteristics using negative binomial regression. Next, we used heteroscedastic ordered logistic regression to relate context-specific drinking frequencies and continued volumes to five drinking-related problems (Alcohol Use Disorders Identification Test scores, physiological problems, risky sex, social problems, and driving after drinking too much). To estimate population-level effects, we assessed drinking frequencies relative to mean past-year use of each drinking context.

RESULTS

Higher individual annual income (>$60,000) was associated with more frequent drinking in all on-premise drinking contexts (bars/clubs, restaurants, and stadiums). Heavier overall drinking was associated with drinking more frequently at bars. Drinking more frequently in respondents' own homes and heavier drinking at friends'/relatives' homes were associated with most drinking-related problems. The population-level effects of physiological problems and driving after drinking too much were highest for parties and friends'/relatives' homes, whereas that of risky sex outcomes was highest for bars.

CONCLUSIONS

Assessing context-specific risks related to heavy and/or frequent drinking, in combination with scaling these risks to determine population-level impacts, can help tailor interventions to reduce alcohol-related problems across different on- and off-premise contexts.

The role of alcohol outlet visits derived from mobile phone location data in enhancing domestic violence prediction at the neighborhood level

Domestic violence (DV) is a serious public health issue, with 1 in 3 women and 1 in 4 men experiencing some form of partner-related violence every year. Existing research has shown a strong association between alcohol use and DV at the individual level. Accordingly, alcohol use could also be a predictor for DV at the neighborhood level, helping identify the neighborhoods where DV is more likely to happen. However, it is difficult and costly to collect data that can represent neighborhood-level alcohol use especially for a large geographic area. In this study, we propose to derive information about the alcohol outlet visits of the residents of different neighborhoods from anonymized mobile phone location data, and investigate whether the derived visits can help better predict DV at the neighborhood level. We use mobile phone data from the company SafeGraph, which is freely available to researchers and which contains information about how people visit various points-of-interest including alcohol outlets. In such data, a visit to an alcohol outlet is identified based on the GPS point location of the mobile phone and the building footprint (a polygon) of the alcohol outlet. We present our method for deriving neighborhood-level alcohol outlet visits, and experiment with four different statistical and machine learning models to investigate the role of the derived visits in enhancing DV prediction based on an empirical dataset about DV in Chicago. Our results reveal the effectiveness of the derived alcohol outlets visits in helping identify neighborhoods that are more likely to suffer from DV, and can inform policies related to DV intervention and alcohol outlet licensing.

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 (β = .008, SE = .003, p < .01), and volume consumed in public places was associated negatively with this outcome (β = -.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.

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.

Investigating Relationships Between Drinking Venues, Drinking Companions, and Corporal Punishment of Children

Limited evidence suggests that how much a parent drinks in a particular venue, such as a bar, restaurant, or a friend's home, is associated with use of corporal punishment. However, these relationships could differ depending on their drinking companions (e.g., spouse or friends). In this study, weighted zero-inflated Poisson models were used to examine whether the relationships between venue-specific drinking frequency, heavier drinking, and corporal punishment are moderated by drinking companions in a mixed-mode sample of parents ( n = 1,599). The relationships between drinking frequency, heavier drinking, and corporal punishment varied by drinking companions, with some combinations being protective and others conferring risk. While most alcohol screening tools focus on individual alcohol use, more nuanced assessment examining where and with whom parents are drinking could be helpful in understanding risk of physical discipline.

Violent crime redistribution in a city following a substantial increase in the number of off-sale alcohol outlets: A Bayesian analysis

INTRODUCTION AND AIMS

This study examined whether the introduction of a large number of off-premise alcohol outlets into a city over a brief period of time could affect rates of violent crime.

DESIGN AND METHODS

The study analysed annual counts of violent crime across 172 US Census block groups in Lubbock, Texas from 2006 through 2011. Spatial Poisson models related annual violent crime counts within each block group to off-premise and on-premise alcohol outlets active during this time period as well as neighbourhood socio-demographic characteristics. The effects of alcohol outlets were assessed both within block groups and across adjacent block groups.

RESULTS

On-premise outlets had a small, significant positive association with violence within a given block group. A similar well-supported local effect for off-premise outlets was not found. However, the spatially lagged effect for off-sale premises was well-supported, indicating that greater densities of these outlets were related to greater rates of violent crime in adjacent areas.

DISCUSSION AND CONCLUSIONS

While these analyses confirmed a previous time-series analysis in finding no city-wide effect of the increase in off-premise outlets, they do suggest that such outlets in a local area may be related to violence in nearby geographic areas. They indicate the importance of examining neighbourhood-specific effects of alcohol outlets on violence in addition to the city-wide effects. They also present further evidence supporting the need to examine the differential effects of on-sale and off-sale premises.

Neighborhood Predictors of Intimate Partner Violence: A Theory-Informed Analysis Using Hierarchical Linear Modeling

Due to high prevalence rates and deleterious effects on individuals, families, and communities, intimate partner violence (IPV) is a significant public health problem. Because IPV occurs in the context of communities and neighborhoods, research must examine the broader environment in addition to individual-level factors to successfully facilitate behavior change. Drawing from the Social Determinants of Health framework and Social Disorganization Theory, neighborhood predictors of IPV were tested using hierarchical linear modeling. Results indicated that concentrated disadvantage and female-to-male partner violence were robust predictors of women's IPV victimization. Implications for theory, practice, and policy, and future research are discussed.

Sexual-orientation differences in drinking patterns and use of drinking contexts among college students

BACKGROUND

Evidence suggests there are important sexual-orientation differences in alcohol consumption, particularly among women. Little is known about where gay/lesbian and bisexual college students drink or differences in drinking patterns derived from graduated frequency measures between heterosexual, gay/lesbian, and bisexual students. The goal of this analysis was to examine patterns of alcohol consumption-including drinking prevalence, quantity, frequency, and contexts of use-by sexual orientation.

METHODS

Data on sexual identity, gender, drinking behaviors, and drinking contexts were examined from repeated cross-sectional samples of undergraduate students attending 14 public California universities from 2003-2011 (n=58,903). Multivariable statistical techniques were employed to examine sexual-orientation differences stratified by gender.

RESULTS

Gay males, lesbians, and bisexual females were significantly more likely to report drinking alcohol in the current semester than their same-gender heterosexual peers (relative risks ranged from 1.07 to 1.10, p-values <0.01). Among current drinkers, bisexual females consumed 7 or more drinks and lesbians consumed 10 or more drinks on significantly more days than heterosexual females. On the other hand, gay male drinkers consumed 8 or more drinks on significantly fewer days than heterosexual male drinkers. Compared to their same-gender heterosexual peers: lesbian/gay and bisexual students drank less frequently at Greek parties (incidence rate ratios [IRRs] ranged from 0.52 to 0.73, p-values <0.01); lesbians (IRR=0.84, p=0.043) and bisexual males (IRR=0.82, p=0.009) drank less frequently at off-campus parties; and gay males drank more frequently outdoors (IRR=1.63, p<0.001) and at bars/restaurants (IRR=1.21, p=0.013).

CONCLUSIONS

Alcohol prevention programs and future research should consider sexual-orientation differences in drinking patterns and use of drinking contexts.

Reducing HIV Risks in the Places Where People Drink: Prevention Interventions in Alcohol Venues

Apart from individual alcohol drinking behavior, the context or places where people drink play a significant role in HIV transmission risk. In this paper, we review the research that has been conducted on alcohol venues to identify the social and structural factors (e.g., social norms, sexual behavior) that are associated with HIV risk in these places, to review HIV prevention interventions based in alcohol venues, and to discuss appropriate methodologies for alcohol venue research. Alcohol venues are defined here as places that sell or serve alcohol for onsite consumption, including bars, bottle stores, nightclubs, wine shops, and informal shebeens. Despite the many established HIV risk factors at play in alcohol venues, limited prevention strategies have been implemented in such places. A total of 11 HIV prevention interventions or programs were identified. HIV prevention interventions in alcohol venues may be conducted at the individual, social, or structural level. However, multilevel interventions that target more than one level appear to lead to the most sustainable behavior change. Strategies to incorporate alcohol venues in biomedical prevention strategies including antiretroviral therapy for alcohol users are also discussed.

Differences in alcohol use and alcohol-related problems between transgender- and nontransgender-identified young adults

BACKGROUND

Little is known about differences in alcohol use and alcohol-related problems between transgender- and nontransgender-identified populations. Using data from a large-scale health survey, we compare the drinking patterns and prevalence of alcohol-related problems of transgender-identified individuals to nontransgender-identified males and females. For transgender-identified people, we examine how various forms of victimization relate to heavy episodic drinking (HED).

METHODS

Cross-sectional surveys were completed by 75,192 students aged 18-29 years attending 120 post-secondary educational institutions in the United States from 2011 to 2013. Self-reported measures included alcohol use, alcohol-related problems, victimization, and sociodemographics, including 3 gender-identity groups: transgender-identified individuals; nontransgender-identified males; and nontransgender-identified females.

RESULTS

Compared to transgender-identified individuals, nontransgender-identified males were more likely to report HED in the past 2 weeks (relative risk=1.42; p=0.006); however, nontransgender-identified males and females reported HED on fewer days than transgender-identified people (incidence-rate ratios [IRRs] ranged from 0.28 to 0.43; p-values<0.001). Compared to transgender-identified people, nontransgender-identified males and females had lower odds of past-year alcohol-related sexual assault and suicidal ideation (odds ratios ranged from 0.24 to 0.45; p-values<0.05). Among transgender-identified people, individuals who were sexually assaulted (IRR=3.21, p=0.011) or verbally threatened (IRR=2.42, p=0.021) in the past year had greater HED days than those who did not experience those forms of victimization.

CONCLUSIONS

Compared to transgender-identified people, nontransgender-identified males and females: have fewer HED occasions (despite nontransgender-identified males having greater prevalence of HED); and are at lower risk for alcohol-related sexual assaults and suicidal ideation. Experiences of sexual assault and verbal threats are associated with greater HED occasions for transgender-identified people.

Alcohol outlet density, drinking contexts and intimate partner violence: a review of environmental risk factors

Alcohol use is a robust predictor of intimate partner violence (IPV). A critical barrier to progress in preventing alcohol-related IPV is that little is known about how an individual's specific drinking contexts (where, how often, and with whom one drinks) are related to IPV, or how these contexts are affected by environmental characteristics, such as alcohol outlet density and neighborhood disadvantage. The putative mechanism is the social environment in which drinking occurs that may promote or strengthen aggressive norms. Once these contexts are known, specific prevention measures can be put in place, including policy-oriented (e.g., regulating outlet density) and individually oriented (e.g., brief interventions to reduce risk for spousal aggression) measures targeting at-risk populations. This paper reviews applicable theories and empirical research evidence that links IPV to drinking contexts and alcohol outlet density, highlights research gaps, and makes recommendations for future research.

Discrepant Patterns of Heavy Drinking, Marijuana Use, and Smoking and Intimate Partner Violence: Results From the California Community Health Study of Couples

This study analyzed whether discrepant (husband or wife use only) or concordant (both partners use) patterns of heavy drinking, marijuana use, and smoking are associated with increased risk for male-to-female partner violence and female-to-male partner violence among adult couples. Based on a geographic sample of married or cohabiting couples residing in 50 California cities, logistic regression analyses were conducted using dyadic data on past-year partner violence, binge drinking and frequency of intoxication, marijuana use, and smoking. When all substance use patterns were included simultaneously, wife-only heavy drinking couples were at elevated risk for male-to-female partner violence, as were concordant marijuana-using couples. Husband-only marijuana discrepant couples were at increased risk for female-to-male partner violence. Further research is needed to explore the processes by which discrepant and concordant substance use patterns may contribute to partner aggression.

The role of alcohol policies in preventing intimate partner violence: a review of the literature

OBJECTIVE

This article summarizes existing research on the relationship between alcohol policies and intimate partner violence (IPV). Because alcohol use represents an important risk factor for IPV, interventions and policies aimed at decreasing problem drinking may also lead to reductions in IPV.

METHOD

Electronic databases were searched to identify relevant peer-reviewed journal articles on alcohol policies and IPV, as well as reference sections of appropriate articles. Only policies that have been studied specifically for their impact on IPV were included.

RESULTS

Three alcohol policy areas (outlet density, hours and days of sale, and pricing/taxation) have been studied in relation to IPV outcomes. Research on outlet density has the most consistent findings, with most studies indicating that higher densities of alcohol outlets are associated with higher rates of IPV. Fewer studies have been conducted on pricing policies and policies restricting hours/days of sale, with most studies suggesting no impact on IPV rates.

CONCLUSIONS

A higher density of alcohol outlets appears to be associated with greater rates of IPV. However, there is limited evidence suggesting that alcohol pricing policies and restrictions on hours and days of sale are associated with IPV outcomes. Knowledge about the impact of alcohol-related policies on IPV and violence in general is limited by several significant research gaps. Additional research is needed to assess the impact of alcohol policies on IPV and other forms of violence.

Alcohol interventions, alcohol policy and intimate partner violence: a systematic review

BACKGROUND

Intimate partner violence (IPV) is a significant global public health issue. The consistent evidence that alcohol use by one or both partners contributes to the risk and severity of IPV suggests that interventions that reduce alcohol consumption may also reduce IPV. This study sought to review the evidence for effects on IPV of alcohol interventions at the population, community, relationship and individual levels using the World Health Organization ecological framework for violence.

METHODS

Eleven databases including Medline, PsycINFO, CINAHL and EMBASE were searched for English-language studies and grey literature published 1 January 1992 - 1 March 2013 investigating whether alcohol interventions/policies were associated with IPV reduction within adult (≥ 18) intimate relationships. Eleven studies meeting design criteria for attributing effects to the intervention and ten studies showing mediation of alcohol consumption were included in the review. The heterogeneity of study designs precluded quantitative meta analysis; therefore, a critical narrative approach was used.

RESULTS

Population-level pricing and taxation studies found weak or no evidence for alcohol price changes influencing IPV. Studies of community-level policies or interventions (e.g., hours of sale, alcohol outlet density) showed weak evidence of an association with IPV. Couples-based and individual alcohol treatment studies found a relationship between reductions in alcohol consumption and reductions in IPV but their designs precluded attributing changes to treatment. Randomized controlled trials of combined alcohol and violence treatment programs found some positive effects of brief alcohol intervention as an adjunct to batterer treatment for hazardous drinking IPV perpetrators, and of brief interventions with non-dependent younger populations, but effects were often not sustained.

CONCLUSIONS

Despite evidence associating problematic alcohol use with IPV, the potential for alcohol interventions to reduce IPV has not been adequately tested, possibly because studies have not focused on those most at risk of alcohol-related IPV. Research using rigorous designs should target young adult populations among whom IPV and drinking is highly prevalent. Combining alcohol and IPV intervention/policy approaches at the population, community, relationship and individual-level may provide the best opportunity for effective intervention.

Drinking context-specific associations between intimate partner violence and frequency and volume of alcohol consumption

AIMS

To quantify two specific aspects of drinking in various venues (past-year frequency of drinking in each venue and volume consumed per venue) and assess their relationships with intimate partner violence.

DESIGN, SETTING AND PARTICIPANTS

A geographic sample of married or cohabiting couples residing in 50 medium-to-large cities in California, USA (n = 1585 couples) was obtained. Cross-sectional survey data were collected via confidential telephone interviews.

MEASUREMENTS

Each partner in the couple provided information about past-year male-to-female and female-to-male intimate partner violence (IPV), drinking contexts and psychosocial and demographic factors. Frequency of drinking in six contexts and volume consumed in those contexts were used in censored Tobit models to evaluate associations between IPV and male and female drinking contexts.

FINDINGS

Risks for IPV differed among drinking contexts and were sometimes related to heavier volumes consumed. In fully adjusted models, male partners' frequency of drinking at parties at another's home {β [standard error (SE) 0.130 (0.060]; P = 0.030} was associated with risk for male-to-female IPV and frequency of drinking during quiet evenings at home was associated with risk for female-to-male IPV [β (SE) 0.017 (0.008); P = 0.033]. Female partners' frequency of drinking with friends at home [β (SE) -0.080 (0.037); P = 0.030] was associated with decreased male-to-female IPV, but volume consumed was associated with increased risk [β (SE) 0.049 (0.024); P = 0.044].

CONCLUSIONS

The social context in which drinking occurs appears to play a role in violence against partners, with male violence being linked to drinking away from home and female violence being linked to drinking at home.
